In this proof-of-concept study, ginger-derived nanoparticles (GDNP) were used to examine a role for GDNP-supplemented diet in amelioration of high-fat diet (HFD) induced insulin resistance. Using multiple lines of inquiry, this study revealed that oral administration of GDNP to HFD mice improved host glucose tolerance and insulin response via (1) regulating VAMP7 induction, (2) enhanced the exosomal accumulation of microRNA miR-375 culminating in (3) the inhibition of arylhydrocarbon receptor (AhR) expression and signaling
Hardesty JE, Wahlang B, Prough RA, Head KZ, Wilkey D, Merchant M, Shi H, Jin J, Cave MC. Effect of Epidermal Growth Factor Treatment and Polychlorinated Biphenyl Exposure in a Dietary-Exposure Mouse Model of Steatohepatitis. Environ Health Perspect. 2021 Mar;129(3):37010. doi: 10.1289/EHP8222. Epub 2021 Mar 31. PMID: 33788613; PMCID: PMC8011667
Impact Statement: Our initial research demonstrated that some PCBs bind to the Epidermal Growth Factor Receptor (EGFR) and terminate its activation of normal gene expression in liver. We sought to establish whether co-treatment with epidermal growth factor, a ligand activator for EGFR, would reverse this inhibition by PCBs. While EGR did reverse the action of PCBs as proposed, there were other downstream effects caused by EGR suggesting the growth factor probably wouldn't serve as a therapeutic agent to prevent PCB toxicity due to its side effects.

Impact Statement: In this paper, we showed that deletion of chemokine receptor (CCR2), which is responsible for migration of inflammatory macrophages to the tumor sites, significantly reduced colon tumor burden and progression and increased overall survival of colon cancer mice. In addition, we also identified novel role for CCR2 in migration of Th17 cells (known to promote colonic inflammation and colon tumors) into tumors, where deletion of CCR2 significantly reduced these cells and promoted tumor killing CD8+ T cells. Therefore, targeting CCR2 in colon cancer patients potentially reduce tumor burden and benefit the patients.

Impact Statement: Rodent diabetic models, used to understand the pathophysiology of diabetic cardiomyopathy (DCM), remain several limitations. Engineered cardiac tissue (ECT) with 3D in vitro heart model was used to investigate the structural and functional effect of advanced glycation end-products (AGEs), as the most important pathogenic factor for DCM’s development; This study shows the first time that AGEs-treated murine ECTs recapitulate the key features of DCM's functional, structural, cellular, and molecular pathogenesis as observed in the heart of diabetic mice. This approved that this ex vivo model can be used to investigate cellular structure-function relationships, signaling pathways relevant to DCM and pharmaceutical intervention strategies.

Potential Crosstalk between Sonic Hedgehog-Wingless-related Integration Site Signaling and Neurovascular Molecules: Implications for Blood Brain Barrier Integrity in Autism Spectrum Disorder. J Neurochem. 2021 Jun 25. doi: 10.1111/jnc.15460. Epub ahead of print. PMID: 34169527.
Impact Statement: Autism spectrum disorder (ASD) is a neurodevelopmental disease and its pathogenesis may be attributed to gene-environment interactions. There are no definitive mechanisms explaining how environmental triggers can lead to ASD although brain inflammation, immunity, and oxidative stress are involved. The blood brain barrier (BBB) plays a critical role in controlling brain homeostasis and immune response. The permissive BBB opens the ‘gate’ for environmental ‘saboteurs’ and trigger the pathological events in ASD. In this review, the authors examined the current knowledge on Sonic Hedgehog/Wingless-related integration site (Shh/Wnt) pathways and their roles in BBB function in ASD. The interactions between Wnt-b-catenin and Shh pathways are critical to maintain BBB integrity in the mature brain to prevent influx of pathogens and inflammatory cells. Disruption of the Shh/Wnt crosstalk may compromise the BBB development and function. The ASD patients with genetic mutations of key components of these pathways show severe ASD symptoms. Mechanisms involving ASD-related mutations of Shh/Wnt signaling cause BBB leaks and neuroinflammation, suggesting the BBB integrity plays a vital role in gene-environment interactions in ASD pathogenesis.

PMID: 34142028; PMCID: PMC8188359.
Impact Statement: Since most of the probiotic bacteria currently available in the market belong to the genera Lactobacillus and overcoming bile salt damage to probiotics is a great challenge. In this study, a tiny nanoparticle called exosomes-like nanoparticles (ELNs) isolated from lemon significantly increased the percentage of lactobacillaceae in the presence of bile. This finding is significant because we daily consume a variety of plant-derived products which contain ELNs in our diet. Our findings provide a foundation to further determine whether other types of ELNs also contribute to enhance the survivability of probiotics in gut in general.

Impact statement: Although fibroblast growth factor 1 (FGF1) protects against nonalcoholic fatty liver disease in type 2 diabetic and obese mice, but its clinically translational study was limited mainly because its hyperproliferation has potentially tumorigenic risk, to overcome which, we engineered an FGF1 (i.e., FGF1ΔHBS) that dramatically diminished it’s proliferative potential, yet maintains full metabolic activity of wild-type FGF1. This new FGF1ΔHBS is approved effective for preventing and reversing liver steatosis and steatohepatitis by activating AMPK via hepatocyte FGFR4, and also potentially applied towards clinical use.

Toxicol Appl Pharmacol. 2021 Jul 13:115647. doi: 10.1016/j.taap.2021.115647. Epub ahead of print. PMID: 34271065.
Impact Statement: Exposure to acrolein is linked with cardiopulmonary toxicity and cardiovascular disease (CVD) risk in humans, yet the mechanisms by which acrolein exposure confers CVD risk is unclear. This study showed that acrolein in isolated blood vessels is vasorelaxant at low levels (physiological) yet vasotoxic at high levels (toxicological), while the major metabolite of acrolein, 3-hydroxypropyl mercapturic acid (3HPMA), was weakly vasoactive and non-toxic indicating it likely does not directly account for vascular injury. These findings support the continued use of 3HPMA as a biomarker of acrolein exposure and warrant further research on mechanisms of acrolein-induced vascular injury to develop interventions that can protect human health.

Impact Statement: This is a commentary for a recent study that has brought us many hopes for the potential gene therapy for diabetic cardiomyopathy (DCM). The authors first noticed the significant increase in O-GlcNAc modified proteins in the heart tissues of patients with diabetes, which was positively and inversely correlated with their HbA1c or blood glucose levels and with cardiac ejection fraction, respectively. Then the authors transferred O-GlcNAcase gene with adeno-associated viral vector to diabetic mice with diastolic dysfunction, a typical early feature of DCM. The gene therapy significantly reduced diabetes-increased expression of O-GlcNAc proteins and expressions of pro-fibrotic genes coding the proteins involved in fibrosis, and interstitial and perivascular type I and type III collagen deposition and improved diastolic dysfunction. Therefore, this is a milestone study to confirm the potential therapeutic reversion of DCM by correcting the balance of O-GlcNacylation in the diabetic heart, even though there remain some unanswered issues.

Impact statement: Clinical trials with survival endpoints are typically designed to enroll patients for a specified number of years, (usually 2-3 years) with another specified duration of follow-up (usually 2-3 years). With random accrual time and follow-up time lead to complex censoring patterns. Conflicting findings were observed for comparing cardiovascular events in patients who took Rofecoxib (Vioxx). Here, using extensive simulation studies, we assess the impact of such censorings on statistical procedures for comparing two treatment groups. Clinical studies with survival outcome should be properly designed to maintain power by considering the censoring patterns.

Impact Statement: Levels of fine particulate matter (PM2.5) air pollution are associated with chronic cardiovascular disease in humans; however, understanding of the early changes that foster chronic vascular disease is incomplete. Because perivascular adipose tissue (PVAT) inflammation is implicated in chronic vascular diseases, we investigated early changes in aortic PVAT following short-term air pollution exposure in mice. We found that PM2.5-exposed mice had changes consistent with oxidative stress, vascular dysfunction and insulin resistance in aortic PVAT. The PM2.5-induced changes were absent in mice with overexpression of extracellular superoxide dismutase in the lungs implicating pulmonary oxidative stress as necessary in detrimental vascular changes in PM2.5-exposed mice. As our study connects inhaled PM2.5 and pulmonary oxidative stress with vascular derangement, we expect future research will test potential interventions that may protect public health from the deleterious cardiovascular effects of air pollution exposure.

Serological assessment of SARS-CoV-2 infection during the first wave of the pandemic in Louisville Kentucky. Sci Rep. 2021 Sep 14;11(1):18285. doi: 10.1038/s41598-021-97423-z. PMID: 34521900; PMCID: PMC8440627.
Impact Statement: Serological assays intended for diagnosis, sero-epidemiologic assessment, and measurement of protective antibody titers upon infection or vaccination are essential for managing the SARS-CoV-2 pandemic. We developed an Enzyme-linked Immunosorbent Assay (ELISA) methods for measuring IgG, IgA, and IgM responses to SARS-CoV-2, Spike (S), receptor binding domain (RBD), and nucleocapsid (N) proteins. Our analyses demonstrate a broad immune response among individuals and suggest some non-RBD specific S IgG and IgA antibodies neutralize SARS-CoV-2.

Impact Statement: Our study shows another level of genetic regulation to accomplish the task of frequency discrimination in chick cochlea. We found that many genes involved in sound sensing and processing undergo progressively different alternative splicing along the tonotopic axis. This differentiated transcriptome along the tonotopic axis suggests that the cochlea expresses different combinations of proteins depending on cochlear location, although encoded in the same set of genes, to have unique functional properties suitable for sensing different sound frequencies.

Impact Statement: Benzene is a ubiquitous environmental pollutant. Recent population-based studies suggest that benzene exposure is associated with an increased risk for cardiovascular disease. However, it is unclear whether benzene exposure by itself is sufficient to induce cardiovascular toxicity. We examined the effects of benzene inhalation (50 ppm, 6 h/day, 5 days/week, 6 weeks) or HEPA-filtered air exposure on the biomarkers of cardiovascular toxicity in male C57BL/6J mice. Together, these data suggest that benzene exposure induces endothelial injury, enhances platelet activation and inflammatory processes; and circulatory levels of endothelial cell and platelet-derived microparticles and platelet-leukocyte aggregates are excellent biomarkers of cardiovascular toxicity of benzene.

Impact Statement: Li et. al. demonstrated p38 and ERK MAPK-dependent proteasomal degradation of the anti-fibrotic protein NF-E2 in TGF-β treated human renal proximal (HK-11) cells. Moreover, activation of the proteasome and loss of NF-E2 expression, induced JNK activation and CTGF expression. In contrast, proteasomal inhibition and NF-E2 over-expression, inhibited TGF-β-induced JNK activation an CTGF expression HK-11 cells and type 1 diabetic kidneys. Thus, NF-E2 could serve as a therapeutic target to generate therapies to prevent progression of renal fibrosis, chronic kidney disease, and renal failure associated with diabetes.

Impact Statement: The goal of this work is to highlight the role of a report back process in prompting health behavior change. Report back is active sharing of research findings with participants to prompt behavior change. In particular, research on a theory-driven report back process for environmental risk reduction is limited. Our research team sought to evaluate the impact of a stage-tailored report back process with participants who had high home radon and/or air nicotine levels. We found that tailored report back of research findings to individual participants reduced radon exposure and changed the health behavior necessary to remediate radon and SHS exposure.

Impact Statement: Vinyl chloride (VC) is an organochlorine mainly used to manufacture its polymer polyvinyl chloride, which is extensively used in the manufacturing of consumer products. Recent studies suggest that chronic low dose VC exposure affects glucose homeostasis in high fat diet-fed mice. Our data suggest that even in the absence of high fat diet, exposure to VC (0.8 ppm, 6 h/day, 5 day/week, for 12 weeks) induces glucose intolerance (1.0 g/kg, i.p.) in male C57BL/6 mice.

Impact Statement: This is an editorial from the Editor-in-chief and the 7 Associate Editors of the American Journal of Physiology Heart and Circulatory Physiology that states our expectation that males and females be incorporated into all studies unless a very strong rationale prevents the authors from doing so, starting in 2023. Some examples of rationale include examining processes that occur only in one sex (i.e. cardiovascular complications of pregnancy), or testing the effects of oral contraceptives on cardiovascular health. By including studies utilizing both sexes/genders, this will result in a more complete, unbiased and reliable data set that more accurately mirrors the population.

Impact Statement: Kentucky ranks among the highest in the nation for attention-deficit/hyperactivity disorder (ADHD) prevalence in children aged 4 to 17 years. In 2011, the American Academy of Pediatrics (AAP) released a clinical practice guideline based on the DSM-IV. A guideline revision based on the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) was released in October 2019. In this study, we assessed and described a sample of Kentucky pediatric providers' ADHD practices using the 2011 guideline and DSM-5 diagnostic criteria. Although pediatricians in the KY AAP that responded adhere to the DSM-5 criteria for diagnosing ADHD, pediatric providers' practices would benefit from education in improvements in pharmacotherapy titration, surveillance of coexisting conditions associated with ADHD, discussion of psychosocial interventions, and school support strategies.

Impact Statement: Alcohol consumption and obesity are known risk factors of steatohepatitis. In this paper, Dr. Wenke Feng, Professor of Medicine, and his collaborators, including some in the CIEHS, demonstrated that deficiency of CRAMP is against a high-fat diet plus acute alcohol-induced liver injury. These results suggest that targeting CRAMP could be an effective approach for the prevention/treatment of high-fat diet plus alcohol consumption-induced steatohepatitis.

Impact Statement: Differential Expression (DE) analysis in presence of noises from different sources remains a key challenge in Single-cell RNA-sequencing (scRNA-seq) studies. Earlier practices for addressing this involved borrowing methods from bulk RNA-seq, which are based on non-zero differences in average expressions of genes across cell populations. We evaluate the performance of 19 widely used methods in terms of 13 performance metrics on 11 real scRNA-seq datasets. Our findings suggest that some bulk RNA-seq methods are quite competitive with the single-cell methods, but their performance depends on the underlying models. However, the multi-criteria and combined-data analysis indicates that DECENT and EBSeq are the best options for DE analysis. Our evaluation provides proper guidelines for selecting the proper tool which performs best under particular experimental settings in the context of the scRNA-seq.

Impact Statement: Analysis of images derived from various neuroimaging modalities involves some common goals such as dimension reduction, denoising, and feature extraction. However, since these modalities have vastly different data characteristics, the current analysis is usually performed using distinct analytical tools that are only suitable for a specific imaging modality. In this paper, we present a Distributional Independent Component Analysis (DICA) that represents a new approach that performs decomposition on the distribution level, providing a unified framework for extracting features across imaging modalities with different scales and representations.

Impact Statement: Breast cancer is the most common female cancer diagnosed in the U.S. and the second most common cause of cancer death in women. Chemotherapeutics used to treat breast cancer often have side effects, which are sometimes life-threatening. Moreover, the tumors can develop resistance over time, making breast cancer treatment challenging. In this paper, we show that the oral administration of colored pigments isolated from bilberry/blueberry, called anthocyanidins (Anthos), significantly decrease tumor volume, inhibit the growth and metastasis of breast cancer, sensitize drug-resistant tumor cells, and exhibit a lower rate of lymph node and lung metastasis, compared to control. These mechanistic insights are expected to be valuable for clinical translation of berry Anthos, either alone or as adjuvant to chemotherapy, for the treatment of breast cancer patients.

Impact Statement: The majority of human genes encode multiple protein isoforms. The isoforms are produced from mRNA isoforms edited from the primary transcripts by alternative splicing. This manuscript uses a model cell culture system to show that exposure to an inorganic arsenic compound that naturally contaminates drinking water in many parts of the world markedly disrupts the alternative splicing producing many errant mRNAs, and that the mRNA isoforms produced change over time with chronic exposure. One of the targets of the arsenic appears to be the splicing factor network itself.

Impact Statement: Chronic exposure to inorganic arsenic leads to an increase in both the onset and progression of several human diseases targeting multiple organs (liver, kidney, bladder, skin, intestines, and central nervous system), which is referred to as ‘arsenicosis’. Gut microbial Urolithin A is derived from ellagic acid and ellagitannins (major poly phenolic components in berries and pomegranate) by gut commensal bacteria. The current study reports the beneficial effects of Urolithin A against adverse effects of trivalent arsenic on human gut epithelia, where treatment with Urolithin A protected against arsenic-induced gut epithelial damage. These studies will pave a pathway for preventive and therapeutic applications to mitigate arsenic-elicited adverse health effects, which are currently unavailable.

Impact Statement: In this study, we identify the formation of 2 toxicants, acrolein and glycidol, from the e-cigarette solvent vegetable glycerin. This finding may improve public health via use of a potential biomarker of e-cigarette use such that e-cigarette use can be quantified. Subsequently, the amount of e-cigarette use can be associated with biomarkers of harm including those that reflect cardiorespiratory injury. Overall, this finding may allow us to better predict health risks of chronic use of e-cigarettes.

Impact Statement: Modern society produces and uses huge amounts of plastics and a large percentage of these ultimately accumulate in water systems and landfills, where they eventually degrade into particles of smaller size. While emerging evidence has documented that these microplastics are abundant in water supplies and the food chain where their human consumption is inevitable, the health consequences of such consumption are not completely known. In this study, we supplied mice with drinking water containing different sizes and doses of polystyrene beads and found that they developed obesity and showed early signs of insulin resistance/diabetes. Thus, the consumption of microplastics may promote early cardiovascular disease.

Impact Statement: Aberrant protein glycosylation is a hallmark of cancer, but few drugs targeting cancer glycobiomarkers are currently available. CIEHS members assisting the lab of Nobuyuki Matoba, Ph.D. (UL Department of Pharmacology & Toxicology and Brown Cancer Center) showed that a fusion protein termed a ‘lectibody’ comprised of the high-mannose glycan-binding lectin Avaren and human immunoglobulin G1 (IgG1) Fc (AvFc) selectively recognizes a range of cell lines derived from lung, breast, colon, and blood cancers at nanomolar concentrations. Proteomics studies identified specific AvFc interaction with epidermal growth factor receptor (EGFR) and insulin-like growth factor 1 receptor (IGF1R). AvFc blocked EGFR and IGF1R signaling in cell culture models of cancer and induced potent Fc-mediated cytotoxic effects and significantly restricted A549 and H460 tumor growth in severe combined immunodeficiency (SCID) mice. These findings provided evidence that increased abundance of high-mannose glycans in the glycocalyx of cancer cells can be a druggable target, and AvFc may provide a new tool to probe and target this tumor-associated glycobiomarker.

Impact Statement: In this paper, we develop a hybrid forecasting model that can generate real-time out-of-sample forecasts of COVID-19 outbreaks for five profoundly affected countries, namely the USA, Brazil, India, the UK, and Canada. A novel hybrid approach based on the Theta method and autoregressive neural network (ARNN) model, named Theta-ARNN (TARNN) model. Daily new cases of COVID-19 are nonlinear, non-stationary, and volatile; thus, a single specific model cannot be ideal for future prediction of the pandemic. The proposed method outperforms traditional univariate and hybrid forecasting models for the test datasets on an average.

Impact Statement: Several studies have reported testicular impairments caused by cadmium (Cd) or obesity alone, therefore, this study examined the combined effect of Cd and obesity on the testes and its underlying mechanism remains unclear. demonstrated that exposure to Cd or HFD alone significantly disrupted testicular structure and increased germ cell apoptosis at both 10 and 24 weeks. However, co-exposure to Cd and HFD did not induce the toxic effects that were induced by either alone, which was associated with the activation of the JAK/STAT pathway. These unexpected results need to be further investigated in the future study.

However, the genotoxic and carcinogenic effects of Nano-Ni and the underlying mechanisms are still unclear. This study unraveled the mechanisms underlying Nano-Ni-induced cell malignant transformation. The combined effects of Nano-Ni-induced DNA damage and DNA repair defects through HIF-1α/miR-210/Rad52 pathway probably contribute to Nano-Ni-induced genomic instability and ultimately cell transformation. Our findings will provide information to further elucidate the molecular mechanisms of Nano-Ni-induced genotoxicity and carcinogenicity.

Impact Statement: Histone deacetylases (HDACs) and Sirtuins (SIRT) may have an important role on the N-acetyltransferase 1 (NAT1) acetylation status, affecting its catalytic capacity and having an impact on the downstream functions of this protein. We investigated the contribution of Lysine deacetylases (KDAC) in the catalytic activity of NAT1 using two different breast cancer cell lines: MDA-MB-231 (ER-, PR-, HER2-) and ZR-75-1 (ER+, PR+, HER2+) and tested the ability of Sirtuin and HDAC inhibitors to impact the transcription, translation and function of NAT1. We transiently knocked down (KD) Sirtuin 1/2 and evaluated the role of these specific proteins in the same experimental outcomes. The results show that the acetylation status of NAT1 is an important factor that might have a relevant role in the progression of cancer.

Deletion of arylamine N-acetyltransferase 1 in MDA-MB-231 human breast cancer cells reduces primary and secondary tumor growth in vivo with no significant effects on metastasis. Mol Carcinog. 2022 Feb 8. doi: 10.1002/mc.23392. Epub ahead of print. PMID: 35133049.
Impact Statement: Previous studies showed that inhibition or depletion of N-acetyltransferase (NAT1) in human breast cancer cells diminishes anchorage-independent growth in culture, suggesting that NAT1 contributes to breast cancer growth and metastasis. Metastasis of parental and NAT1 knockout (KO) cells was investigated in vivo in a mouse xenograft model. NAT1 KO MDA-MB-231 cells produced primary tumors smaller than those formed by parental cells, which was contributed by an increased rate of apoptosis in KO cells. The frequency of lung metastasis, however, was not altered in NAT1 KO cells suggesting that NAT1 contributes to primary and secondary tumor growth in vivo in MDA-MB-231 breast cancer cells but does not appear to affect its metastatic potential.

Impact Statement: Early detection of adult and pediatric CKD and detailed mechanistic understandings of the kidney damage may be helpful in delaying or curtailing disease progression. Clinically, serum creatinine and albumin levels can be indicative of CKD, but often are a lagging indicator only significantly affected once kidney function has severely diminished. The evolution of proteomics and mass spectrometry technologies has begun to provide a powerful research tool in defining these mechanisms and identifying novel biomarkers of CKD. This review addresses the potential for improving the clinical toolkit toward better treatment of pediatric kidney diseases aided by current and future development of proteomic applications.

Epub 2021 Oct 15. PMID: 35256941; PMCID: PMC8897044.
Impact Statement: The role of ferroptosis in the pathogenesis of diabetic cardiomyopathy (DCM) was comprehensively examined by examining the expression of key regulators of ferroptosis in type 2 diabetic mice with cardiomyopathy and a new ex vivo DCM model. Diabetes or AGEs was found to induce ferroptosis, reflected through increased levels of Ptgs2 and lipid peroxides and decreased ferritin and SLC7A11 levels and typically morphological changes in cardiomyocytes, and inhibition of ferroptosis with ferrostatin-1 and deferoxamine, as well as Nrf2 activator, sulforaphane, prevented cardiac remodeling and dysfunction. These findings suggest that ferroptosis plays an essential role in the pathogenesis of DCM; sulforaphane prevents ferroptosis and associated pathogenesis via AMPK-mediated NRF2 activation.

Impact Statement: A recent meta-analysis reported N-acetyltransferase 2 (NAT2) slow and intermediate phenotypes had a significantly increased risk of lung cancer. NAT2 activity in humans is thought to be restricted to liver and gastrointestinal tract, and no studies to our knowledge have reported the expression of NAT2 activity in immortalized human lung epithelial cells. Given the importance of NAT2 in cancer and inhalation of various carcinogens directly into the lungs, we investigated NAT2 activity and documented that it is expressed and functional in human lung epithelial cells.

Impact Statement: Following recombinant expression in bacteria, yeast, and mammalian cells, we report significant differences in affinity between human N-acetyltransferase 1 (NAT1) and N-acetyltransferase 2 (NAT2) for its required co-factor acetyl coenzyme A, as well as for N-hydroxy-arylamines activated via O-acetylation. The findings provide important information to understand the relative contribution of human NAT1 vs NAT2 towards N-acetylation and O-acetylation reactions in human hepatic and extrahepatic tissues.

Impact Statement: Human arylamine N-acetyltransferase 1 (NAT1) catalyzes the N-acetylation of arylamine carcinogens such as 4-aminobiphenyl (ABP), and following N-hydroxylation, the O-acetylation of N-hydroxy-arylamine carcinogens such as N-hydroxy-ABP (N-OH-ABP). The effects of individual single nucleotide polymorphisms (SNPs) in the NAT1 coding exon on Michaelis-Menten kinetic constants was assessed for ABP N-acetyltransferase and N-OH-ABP O-acetyltransferase activity following transfection of human NAT1 into COS-1 cells. 560G>A (rs4986782) (R187Q) significantly reduced the apparent Km for ABP and N-OH-ABP a finding that was not observed with any of the other NAT1 SNPs tested. These findings suggest that the role of the 560G>A (rs4986782) (R187Q) SNP cancer risk assessment may be modified by exposure level to aromatic amine carcinogens such as ABP.

In vivo deep network tracing reveals phosphofructokinase-mediated coordination of biosynthetic pathway activity in the myocardium. J Mol Cell Cardiol. 2022 Jan;162:32-42. doi: 10.1016/j.yjmcc.2021.08.013. Epub 2021 Sep 3. PMID: 34487754; PMCID: PMC8766935.
Impact Statement: This study tested how phosphofructokinase-1 (PFK1) activity controls the fate of glucose-derived carbon in murine hearts in vivo. PFK1 activity was regulated by cardiac-specific overexpression of kinase- or phosphatase-deficient 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase transgenes in mice (termed GlycoLo or GlycoHi mice, respectively). Stable isotope (C13) labeled glucose and deep network metabolic tracing revealed that low rates of PFK1 activity, potentially regulated by physical channeling, promoted selective routing of glucose-derived carbon to the purine synthesis pathway to form 5-aminoimidazole-4-carboxamide ribonucleotide. Additionally, PFK1 influenced glucose-derived carbon deposition in glycogen, but did not affect hexosamine biosynthetic pathway activity. These studies demonstrate the utility of deep network tracing to identify metabolic channeling and changes in biosynthetic pathway activity in the heart in vivo and present new potential mechanisms by which metabolic branch point reactions modulate biosynthetic pathways.

Impact Statement: Using the pre-existing large data, we have devolved model to predict onset of early- stage of lung cancer in heavy smokers. The mean age (in years) to make the transition into the preclinical state was 70.94 or 71.15 for male and female heavy smokers respectively. About 90% of heavy smokers who are at risk for lung cancer would enter the preclinical state in age interval (55.7, 85.8) for males and (54.2, 87.7) for females, and the transition peaked around age 69 for both genders. Based on the result, low-dose CT should be started at age 55 and ended before 85 for heavy smokers. This provided important information to policy makers.

Impact Statement: We study the predictors of thrombosis in cancer patients treated with bevacizumab using a single center comprehensive retrospective cohort. The thrombotic events occurred in 24/116 (20.7%) of the hypertension cohort compared to 8/87 (9.2%) of the normotensive patients (p = 0.026) and in 15/52 (28.8%) of hyperlipidemic patients vs 17/151 (11.3%) of those with normal lipids (p = 0.003). The Khorana score was not a significant predictor in this population. In further analyzing our data, we found increasing thrombotic events with each addition of the most telling predictors of thromboses in our population: hypertension, hyperlipidemia, and greater than trace proteinuria, such that patients with all three risk factors present vs none had an odds ratio of 6.786 (p = 0.004). Incorporating these three risk factors into a clinical risk score may help stratify patients into lower and higher risk categories which may assist clinicians in making decisions about the use of prophylactic anticoagulation in this population.

Impact Statement: As an environmental pollutant, cadmium (Cd) has been widely reported to induce male infertility due to its gonadotoxicity. This study found for the first time that exposure to 5 ppm Cd significantly decreased the expression of SLC7A11, a marker of ferroptosis in mice, along with the expression of SLC40A1 mRNA and ferritin heavy chain (FTH) protein, whereas there was no obvious change in the mRNA expression of Tfrc, ZIP8, ZIP14, and NCOA4, suggesting that 5 ppm Cd exposure increased testicular ferroptosis, probably due to the reduction of stored iron export potency.

Impact Statement: Endothelial progenitor cells (EPCs) play a critical role in repairing damaged vessels and triggering ischemic angiogenesis, but their number is reduced, and function is impaired under diabetic conditions. Improving EPC function has been considered a promising strategy to ameliorate diabetic vascular complications. In the present study, we showed that CXCR7 agonist TC14012 can prevent EPCs from high level of glucose-induced dysfunction and apoptosis, improve eNOS activity and NO production via CXCR7/Akt signal pathway, and promote EPC mobilization and diabetic ischemia angiogenesis.

Impact Statement: Developing advanced methods to isolate nanoscale and microscale cell-derived extracellular vesicle (EV) types and subtypes are of significant interest to the EV research community in general given their functional, diagnostic and therapeutic potential. The elasto-inertial focusing system developed in the manuscript is a novel compact microfluidic device that mechanistically works like gold standard differential ultracentrifugation for EV isolation. Because of its compact size, it can potentially be integrated with other microfluidic lab-on-a-chip and similar technologies to enable scalable, continuous separation of small microliter to milliliter volume limited samples upstream or downstream on EV chip-based detection and capture devices.

Impact Statement: Elderly adults are at higher risk for developing diabetic complications including diabetic nephropathy (DN), contributing to excess morbidity and mortality in elderly individuals. A non-mitogenic variant of fibroblast growth factor 1 (FGF1ΔHBS) was found to prevent DN in an early-stage (2-month-old) type 2 diabetes (T2D) mouse model. The present study demonstrated that FGF1ΔHBS was also able to delay the progression of renal dysfunction likely through activating PPARα to prevent renal tubule cell death in late-stage T2D, exhibiting a promising translational potential in treating DN in elderly T2D individuals by ameliorating renal inflammation, fibrosis, and apoptosis.

Impact Statement: Copper oxide nanoparticles (Nano-CuO) are widely used in medical and industrial fields and our daily necessities. However, the biosafety assessment of Nano-CuO is far behind their rapid development. Our study demonstrated that Nano-CuO exposure caused mitochondrial ROS generation, MAPKs activation, and MMP-3 upregulation. Nano-CuO exposure also caused cells to undergo EMT, which was through Nano-CuO-induced dysregulation of ROS/MAPKs/MMP-3 pathway. Our findings will provide further understanding of the potential mechanisms involved in metal nanoparticle-induced various toxic effects including EMT and pulmonary fibrosis.

Impact Statement: Our research sheds direct light on the most accepted explanation for the mode of action of arsenic carcinogenicity in arsenic’s major target organ, skin. Arsenic is known to induce DNA breaks without directly interacting with DNA. We have discovered that a major signaling protein for DNA break repair, ataxia telangiectasia-mutated (ATM), has reduced activation in human keratinocytes chronically exposed to inorganic arsenic. ATM plays an important role in DNA repair by activating enzymes that can fix DNA strand breaks in cells, preventing the accumulation of mutations in cells and carcinogenesis. Thus, it could be hypothesized that arsenic-induced tumors may be more sensitive to certain cancer treatments that induce DNA damage or inhibit DNA repair, such as radiotherapy or PARP inhibitors, respectively. Based on these findings, additional studies are needed determine whether arsenic-induced tumors are sensitive to specific chemotherapeutic regimens. Results from these future studies could be used to design new strategies to treat arsenic-induced cancers.

Exp Biol Med (Maywood). 2022 Apr 27:15353702221090457. doi: 10.1177/15353702221090457. Epub ahead of print. PMID: 35475383.
Impact statement: Methadone (MTD) is a common medication treatment for opioid use disorder (OUD) during pregnancy. In this study, pregnant rats were administrated a dosing approximately equivalent to the OUD treatment and the effects of passive in utero and postnatal MTD exposure on myelin development was investigated in neonatal rat brain. The findings reveal the potential mechanism(s) underlying the association between myelin impairment and antenatal opioid exposure. Our study alongside others concerns for fetal brain development when using MTD to manage the OUD during pregnancy. Improved understanding of the effects of opioid exposure will allow us to design treatments for OUD during pregnancy that minimize effects on the fetal brain or target postnatal treatment to mitigate the effects of antenatal opioid exposure.

Epub ahead of print. PMID: 35654045.
Impact Statement: The gut microbiome has recently revealed itself to be a major player in human health and disease. Here, Drs. Huang-Ge Zhang and collaborators including CIEHS members Michael Merchant and Jun Won Park, show that a small metabolite, isoamylamine (IAA) produce by the bacteria Ruminococcaceae is enriched in aged mice and elderly people. Interestingly a bacteriophage belonging to the Myoviridae family that infects Ruminococcaceae are reduced in these settings. IAA induced cognitive declines in young mice is reversed by Myoviridae phage administration. IAA promoted apoptosis of microglial cells through a p53 dependent mechanism. Our results linked microbiome metabolites to direct transcriptional co-regulation of genomic DNA. These findings suggest a molecular mechanism connecting gut metabolism to gene expression in the brain with implications for disease development.

Impact Statement: Metabolomics has emerged as a powerful method to provide insight into cancer progression, including separating patients into low- and high-risk groups for overall (OS) and progression-free survival (PFS). This proof-of-concept study evaluates metabolites as biomarkers obtained directly from tumor core biopsies along with covariates age, sex, pathological stage at diagnosis (I/II vs. III/VI), histological subtype, and treatment vs. no treatment. A prediction model is developed to stratify patients into low- and high-risk groups based on log-transformed intensities of key metabolites. Risk scores based on 10 metabolites for OS and 5 metabolites for PFS were significant predictors of survival. Risk scores were validated with SPLS-DA classification model (AUROC 0.868 for OS and AUROC 0.755 for PFS, when combined with covariates. Thus, metabolomic analysis of lung tumor core biopsies has the potential to differentiate patients into low- and high-risk groups based on OS and PFS events and probability.

Epub ahead of print. PMID: 35730646.
Impact Statement: To identify histidyl dipeptide-mediated responses in the heart, we used an integrated triomics approach, which involved genome-wide RNA sequencing, global proteomics, and unbiased metabolomics to identify the effects of cardiospecific transgenic overexpression of the carnosine synthesizing enzyme, carnosine synthase (Carns), in mice. Our result showed that higher myocardial levels of histidyl dipeptides were associated with extensive changes in the levels of several microRNAs, which target the expression of contractile proteins, β-fatty acid oxidation, and citric acid cycle (TCA) enzymes. Global proteomic analysis showed enrichment in the expression of contractile proteins, enzymes of β-fatty acid oxidation, and the TCA in the Carns transgenic heart. Integration of multiple data sets suggested that β-fatty acid oxidation and TCA pathways exhibit correlative changes in the Carns transgenic hearts at all 3 levels. Conclusions Taken together, these findings reveal a central role of histidyl dipeptides in coordinated regulation of myocardial structure, function, and energetics.

Impact Statement: Liver disease associated with long-term heavy drinking of alcoholic beverages is a major health problem with no FDA-approved therapies. In this paper, we describe a previously unknown mediator of alcohol’s adverse effects on the liver: the alpha4 subunit of nicotinic acetylcholine receptors. These neurotransmitter receptors are known to be important in the brain, where they are involved in the reward pathways activated by both nicotine and alcohol. The discovery that they are also expressed in the liver and contribute to some of the earliest manifestations of alcohol-associated liver disease points to a new target for potential therapeutic interventions.
