Activation of the cannabinoid CB2 receptor increases renal perfusion.

Physiol Genomics 2019 Feb 1. Epub 2019 Feb 1.

Pharmaceutical Sciences, University of Tennessee Health Sciences Center, United States.

Acute kidney injury (AKI) is an increasing problem clinically and is associated with chronic kidney disease progression. Cannabinoid type 2 receptor activation has been shown to mitigate some of the deleterious tubular effects due to AKI, but its role on the renal vasculature has not been fully described. In this study, we investigated the effects of our novel cannabinoid CB2 receptor agonist, SMM-295, on renal vasculature by assessing cortical perfusion using laser Doppler flowmetry and changes in luminal diameter using isolated afferent arterioles.

The Role of Gut Metabolism of Adrenal Corticosteroids and Hypertension - Clues Gut Cleansing Antibiotics Give Us.

Physiol Genomics 2019 Jan 25. Epub 2019 Jan 25.

Pediatric Nephrology, Rhode Island Hospital, United States.

Intestinal bacteria can metabolize sterols, bile acids, steroid hormones, dietary proteins, fiber, foodstuffs, and short chain fatty acids (SCFCs). The metabolic products generated by some of these intestinal bacteria have been linked to a number of systemic diseases including obesity with type 2 diabetes mellitus, some forms of inflammation, and more recently, systemic hypertension. In this review, we primarily focus on the potential role selected gut bacteria play in metabolizing the endogenous glucocorticoids corticosterone and cortisol. Read More

Differential circRNA expression profiles in latent human cytomegalovirus infection and validation using clinical samples.

Physiol Genomics 2019 Feb 21;51(2):51-58. Epub 2018 Dec 21.

Department of Clinical Laboratory, the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University , Wenzhou, Zhejiang , China.

Human cytomegalovirus (HCMV) is an opportunistic prototypic beta-herpesvirus that can cause severe and even fatal diseases in immune-naive newborns and immunocompromised adults. Host-virus interactions occurring at the transcriptional and posttranscriptional levels are critical for establishing an HCMV latent or lytic infection, but the mechanisms remain poorly understood. Herein, we investigated the expression of circRNAs in human leukemia monocytes (THP-1 cells) latently infected with HCMV and explored the diagnostic value of circRNAs in children with HCMV infection.

Identification of molecular signatures of cystic fibrosis disease status with plasma-based functional genomics.

Physiol Genomics 2019 Jan 12;51(1):27-41. Epub 2018 Dec 12.

Division of Endocrinology, Department of Pediatrics, Medical College of Wisconsin , Milwaukee, Wisconsin.

Although cystic fibrosis (CF) is attributed to dysfunction of a single gene, the relationships between the abnormal gene product and the development of inflammation and progression of lung disease are not fully understood, which limits our ability to predict an individual patient's clinical course and treatment response. To better understand CF progression, we characterized the molecular signatures of CF disease status with plasma-based functional genomics. Peripheral blood mononuclear cells (PBMCs) from healthy donors were cultured with plasma samples from CF patients ( n = 103) and unrelated, healthy controls ( n = 31). Read More

School of Health and Life Sciences, Federation University Australia , Victoria , Australia.

Background And Aims: Fetal and postnatal growth restriction cause a predisposition to cardiovascular disease (CVD) in adulthood. Telomeres are repetitive DNA-protein structures that protect chromosome ends, and the loss of these repeats (a reduction in telomere length) is associated with CVD. As exercise preserves telomere length and cardiovascular health, the aim of this study was to determine the effects of growth restriction and exercise training on cardiac telomere length and telomeric genes.

Natriuretic peptides (NPs) exert diverse effects on several biological and physiological systems, such as kidney function, neural and endocrine signaling, energy metabolism, and cardiovascular function, playing pivotal roles in the regulation of blood pressure (BP) and cardiac and vascular homeostasis. NPs are collectively known as anti-hypertensive hormones and their main functions are directed toward eliciting natriuretic/diuretic, vasorelaxant, anti-proliferative, anti-inflammatory, and anti-hypertrophic effects, thereby, regulating the fluid volume, BP, and renal and cardiovascular conditions. Interactions of NPs with their cognate receptors display a central role in all aspects of cellular, biochemical, and molecular mechanisms that govern physiology and pathophysiology of BP and cardiovascular events.

Neuronal (pro)renin receptor regulates deoxycorticosterone-induced sodium intake.

Physiol Genomics 2018 Oct 24;50(10):904-912. Epub 2018 Aug 24.

Pharmacology and Department of Physiology and Cell Biology, University of Nevada, Reno, School of Medicine , Reno, Nevada.

Increased sodium appetite is a physiological response to sodium deficiency; however, it has also been implicated in disease conditions such as congestive heart failure, kidney failure, and salt-sensitive hypertension. The central nervous system is the major regulator of sodium appetite and intake behavior; however, the neural mechanisms underlying this behavior remain incompletely understood. Here, we investigated the involvement of the (pro)renin receptor (PRR), a component of the brain renin-angiotensin system, in the regulation of sodium intake in a neuron-specific PRR knockout (PRRKO) mouse model generated previously in our laboratory.

Gut microbiota are associated with a variety of complex polygenic diseases. The usage of broad-spectrum antibiotics by patients affected by such diseases is an important environmental factor to consider, because antibiotics, which are widely prescribed to curb pathological bacterial infections, also indiscriminately eliminate gut commensal microbiota. However, the extent to which antibiotics reshape gut microbiota and per se contribute to these complex diseases is understudied. Read More

Global transcriptional differences in myokine and inflammatory genes in muscle of mature steer progeny are related to maternal lactation diet and muscle composition.

Physiol Genomics 2018 Oct 3;50(10):884-892. Epub 2018 Aug 3.

Department of Animal Sciences, Purdue University , West Lafayette, Indiana.

Steer progeny suckled by cows fed a dried distillers grains and solubles (DDGS) diet the first 3 mo of lactation were heavier during feedlot finishing and had significantly lower marbling and larger longissimus muscles than steers suckled by cows fed a control diet (CON). These differences were profound in that progeny were managed and fed identically from weaning until finishing, and findings suggest that the suckling period established the developmental program of muscle composition. Here transcriptomes of longissimus muscle were measured by next-generation sequencing to investigate whether there were any developmental clues to the differences in marbling scores and muscle content between steers suckled by DDGS ( n = 5) vs. Read More

Exploring miRNA-mRNA regulatory network in cardiac pathology in Na/H exchanger isoform 1 transgenic mice.

Physiol Genomics 2018 Oct 20;50(10):846-861. Epub 2018 Jul 20.

Department of Pediatrics, University of California San Diego , La Jolla, California.

Numerous studies have demonstrated that Na/H exchanger isoform 1 (NHE1) is elevated in myocardial diseases and its effect is detrimental. To better understand the involvement of NHE1, we have previously studied cardiac-specific NHE1 transgenic mice and shown that these mice develop cardiac hypertrophy, interstitial fibrosis, and cardiac dysfunction. The purpose of current study was to identify microRNAs and their mRNA targets involved in NHE1-mediated cardiac injury. Read More

High-throughput profiling of the circulating proteome suggests sexually dimorphic corticosteroid signaling following ischemic stroke.

Physiol Genomics 2018 Oct 20;50(10):876-883. Epub 2018 Jul 20.

Valtari Bio Incorporated, Morgantown, West Virginia.

Increasing evidence suggests that there are innate differences between sexes with respect to stroke pathophysiology; however, the molecular mechanisms underlying these differences remain unclear. In this investigation, we employed a shotgun approach to broadly profile sex-associated differences in the plasma proteomes of a small group of male ( n = 6) and female ( n = 4) ischemic stroke patients. Peripheral blood was sampled during the acute phase of care, and liquid chromatography electrospray ionization mass spectrometry was used to quantify plasma proteins. Read More

R213G polymorphism in SOD3 protects against bleomycin-induced inflammation and attenuates induction of proinflammatory pathways.

Physiol Genomics 2018 Sep 13;50(9):807-816. Epub 2018 Jul 13.

Developmental Lung Biology and Cardiovascular Pulmonary Research Laboratories, Departments of Pediatrics and Medicine, University of Colorado, Anschutz Medical Campus, Aurora, Colorado.

Extracellular superoxide dismutase (EC-SOD), one of three mammalian SOD isoforms, is the sole extracellular enzymatic defense against superoxide. A known human single nucleotide polymorphism (SNP) in the matrix-binding domain of EC-SOD characterized by an arginine-to-glycine substitution at position 213 (R213G) redistributes EC-SOD from the matrix into extracellular fluids. We previously reported that knock-in mice harboring the human R213G SNP (R213G mice) exhibited enhanced resolution of inflammation with subsequent protection against fibrosis following bleomycin treatment compared with wild-type (WT) littermates.

Persistent pulmonary hypertension alters the epigenetic characteristics of endothelial nitric oxide synthase gene in pulmonary artery endothelial cells in a fetal lamb model.

Physiol Genomics 2018 Oct 13;50(10):828-836. Epub 2018 Jul 13.

Division of Neonatology, Department of Pediatrics, Medical College of Wisconsin , Milwaukee, Wisconsin.

Decreased expression of endothelial nitric oxide synthase (eNOS), a key mediator of perinatal transition, characterizes persistent pulmonary hypertension of the newborn (PPHN) in neonates and a fetal lamb model; the mechanisms are unclear. We investigated whether increased DNA CpG methylation at the eNOS promoter in estrogen response elements (EREs) and altered histone code together contribute to decreased eNOS expression in PPHN. We isolated pulmonary artery endothelial cells (PAEC) from fetal lambs with PPHN induced by prenatal ductus arteriosus constriction from 128 to 136 days gestation or gestation-matched twin controls.

Division of Nutritional Sciences, Cornell University , Ithaca, New York.

Primary human muscle progenitor cells (hMPCs) are commonly used to understand skeletal muscle biology, including the regenerative process. Variability from unknown origin in hMPC expansion capacity occurs independently of disease, age, or sex of the donor. We sought to determine the transcript profile that distinguishes hMPC cultures with greater expansion capacity and to identify biological underpinnings of these transcriptome profile differences.

Influenza virus infection modulates the death receptor pathway during early stages of infection in human bronchial epithelial cells.

Physiol Genomics 2018 Sep 29;50(9):770-779. Epub 2018 Jun 29.

Allergy and Clinical Immunology Branch, Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention , Morgantown, West Virginia.

Host-viral interaction occurring throughout the infection process between the influenza A virus (IAV) and bronchial cells determines the success of infection. Our previous studies showed that the apoptotic pathway triggered by the host cells was repressed by IAV facilitating prolonged survival of infected cells. A detailed understanding on the role of IAV in altering the cell death pathway during early-stage infection of human bronchial epithelial cells (HBEpCs) is still unclear. Read More

A mini review: Proteomics approaches to understand disused vs. exercised human skeletal muscle.

Physiol Genomics 2018 Sep 29;50(9):746-757. Epub 2018 Jun 29.

Division of Cardiology, Department of Medicine, University of California San Diego , La Jolla, California.

Immobilization, bed rest, or denervation leads to muscle disuse and subsequent skeletal muscle atrophy. Muscle atrophy can also occur as a component of various chronic diseases such as cancer, AIDS, sepsis, diabetes, and chronic heart failure or as a direct result of genetic muscle disorders. In addition to this atrophic loss of muscle mass, metabolic deregulation of muscle also occurs. Read More

Genetics of guanylyl cyclase pathways in the cochlea and their influence on hearing.

Physiol Genomics 2018 Sep 29;50(9):780-806. Epub 2018 Jun 29.

Department of Biomedical Sciences, University of Minnesota Medical School , Duluth, Minnesota.

Although hearing loss is the most common sensory deficit in Western societies, there are no successful pharmacological treatments for this disorder. Recent experiments have demonstrated that manipulation of intracellular cyclic guanosine monophosphate (cGMP) concentrations can have both beneficial and harmful effects on hearing. In this review, we will examine the role of cGMP as a key second messenger involved in many aspects of cochlear function and discuss the known functions of downstream effectors of cGMP in sound processing.

Identification of nine novel loci related to hematological traits in a Japanese population.

Physiol Genomics 2018 Sep 29;50(9):758-769. Epub 2018 Jun 29.

Department of Human Functional Genomics, Advanced Science Research Promotion Center, Mie University, Tsu, Mie , Japan.

Recent genome-wide association studies have identified various genetic variants associated with hematological traits. Although it is possible that quantitative data of hematological traits are varied among the years examined, conventional genome-wide association studies have been conducted in a cross-sectional manner that measures traits at a single point in time. To address this issue, we have traced blood profiles in 4,884 Japanese individuals who underwent annual health check-ups for several years. Read More

Proteomic determination of the lysine acetylome and phosphoproteome in the rat native inner medullary collecting duct.

Physiol Genomics 2018 Sep 22;50(9):669-679. Epub 2018 Jun 22.

Epithelial Systems Biology Laboratory, Systems Biology Center, National Heart, Lung, and Blood Institute, National Institutes of Health , Bethesda, Maryland.

Phosphorylation and lysine (K)-acetylation are dynamic posttranslational modifications of proteins. Previous proteomic studies have identified over 170,000 phosphorylation sites and 15,000 K-acetylation sites in mammals. We recently reported that the inner medullary collecting duct (IMCD), which functions in the regulation of water-reabsorption, via the actions of vasopressin, expresses many of the enzymes that can modulated K-acetylation.

GNAI2 polymorphic variance associates with salt sensitivity of blood pressure in the Genetic Epidemiology Network of Salt Sensitivity study.

Physiol Genomics 2018 Sep 15;50(9):724-725. Epub 2018 Jun 15.

Department of Pharmacology & Experimental Therapeutics and The Whitaker Cardiovascular Institute, Boston University School of Medicine , Boston, Massachusetts.

Salt sensitivity of blood pressure (BP) increases hypertension risk and associated adverse cardiovascular outcomes. At present, there are no validated rapid tests or diagnostic markers to identify salt sensitivity of BP in clinical practice. Based on our prior animal studies that report a role for brain Gαi proteins in the salt sensitivity of BP and evidence that GNAI2 single nucleotide polymorphisms (SNPs) associate with hypertension risk, we investigated the hypothesis that GNAI2 SNPs associate with salt sensitivity of BP in humans.

Feed-efficient pigs exhibit molecular patterns allowing a timely circulation of hormones and nutrients.

Physiol Genomics 2018 Sep 15;50(9):726-734. Epub 2018 Jun 15.

Institute of Genome Biology, Leibniz Institute for Farm Animal Biology (FBN), Dummerstorf, Germany.

Feed efficiency (FE) is a measure of the rate between feed intake and body weight gain and is subject to constant progress in pigs, based on extensive performance tests and analyses of physiological parameters. However, endocrine regulatory circuits that comprise the sensation and perception of intrinsic requirements and appropriate systemic responses have not yet been fully elucidated. It is hypothesized that the gut-brain axis, which is a network of hierarchical anterior regulatory tissues, contributes largely to variations in FE. Read More

Muscle miRNAome shows suppression of chronic inflammatory miRNAs with both prednisone and vamorolone.

Physiol Genomics 2018 Sep 8;50(9):735-745. Epub 2018 Jun 8.

Center for Genetic Medicine Research, Children's National Medical Center , Washington, District of Columbia.

Corticosteroids are highly prescribed and effective anti-inflammatory drugs but the burden of side effects with chronic use significantly detracts from patient quality of life, particularly in children. Developing safer steroids amenable to long-term use is an important goal for treatment of chronic inflammatory diseases such as Duchenne muscular dystrophy (DMD). We have developed vamorolone (VBP15), a first-in-class dissociative glucocorticoid receptor (GR) ligand that shows the anti-inflammatory efficacy of corticosteroids without key steroid side effects in animal models.

Research Institute for Sport & Exercise Sciences, Liverpool John Moores University, Liverpool, United Kingdom.

We investigated whether single nucleotide polymorphisms (SNPs) within genes encoding the alpha-1 chain of type I ( COL1A1, rs2249492 ; rs1800012 ), type II ( COL2A1, rs2070739 ), and type V (COL5A1, rs12722 ) collagen were associated with the variable response to exercise-induced muscle damage (EIMD). Knee extensor muscle strength and soreness were assessed pre-, post-, and 48 h post-EIMD (120 maximal eccentric knee extensor contractions) in 65 young healthy participants, who were genotyped for the aforementioned SNPs. We found that COL1A1 (minor) T-allele carriers ( rs1800012 ) and (major) T-allele homozygotes ( rs2249492 ) were generally weaker ( P ≤ 0. Read More
