Project description:Background: There are more than 1 million persons living with HIV/AIDS (PLWHA) in the United States and approximately 40% of them have a history of alcohol use disorders (AUD). Chronic heavy alcohol consumption and HIV/AIDS both result in reduced lean body mass and muscle dysfunction, increasing the incidence of comorbid conditions. Previous studies from our laboratory using rhesus macaques infected with Simian immunodeficiency Virus (SIV) demonstrated that chronic binge alcohol (CBA) administration in the absence of antiretroviral therapy exacerbates skeletal muscle (SKM) wasting at end-stage SIV disease. The aim of this study was to characterize how CBA alters global gene regulatory networks that lead to SKM wasting at end-stage disease. Administration of intragastric alcohol or sucrose to male rhesus macaques began 3 months prior to SIV infection and continued throughout the duration of study. High-output array analysis was used to determine CBA-dependent changes in mRNA expression, miRNA expression, and promoter methylation status of SKM at end-stage disease (~10 months post-SIV) from healthy control (control), sucrose-administered, SIV-infected (SUC/SIV), and CBA-administered/SIV-infected (CBA/SIV) macaques. Results: In addition to previously reported effects on the extracellular matrix and the promotion of a pro-inflammatory environment, we found that CBA adversely affects gene regulatory networks that involve universal cellular functions, protein homeostasis, calcium and ion homeostasis, neuronal growth and signaling, and satellite cell growth and survival. Conclusions: The results from this study provide an overview of the impact of CBA on gene regulatory networks involved in biological functions, including transcriptional and epigenetic processes, illustrating the genetic and molecular mechanisms associated with CBA-dependent SKM wasting at end-stage SIV infection.

Project description:Effective antiretroviral therapy (ART) has significantly reduced mortality of people living with HIV (PLWH). Increased survival and aging of PLWH is associated with increased incidence of at-risk alcohol use and of metabolic comorbidities; and in women, menopause may be an additional factor contributing to metabolic dysregulation, particularly in adipose tissue. We examined the differential effects of chronic binge alcohol (CBA) administration and ovariectomy (OVX) on the omental adipose tissue (OmAT) proteome of simian immunodeficiency virus (SIV) infected macaques. Quantitative discovery-based proteomics identified 1429 differentially expressed proteins. Ingenuity Pathway Analysis calculated z-scores, or activation predictions for a disease or functional pathway. Results revealed functional pathways associated with protein changes centered around the “OmAT metaboproteome profile”. CBA did not affect functional pathways of metabolic disease; but dysregulated proteins involved in AMPK signaling and lipid metabolism. Based on IPA’s calculated z-score, OVX-mediated proteome changes promote pathways associated with glucose and lipid associated metabolic disease. Additionally, OVX was predicted to promote apoptosis, necrosis and reactive oxygen species (ROS) pathways, while CBA was predicted to inhibit these OVX-associated changes. These results provide evidence for the role of ovarian hormone loss in mediating OmAT metaboproteome dysregulation in HIV/SIV and suggest that CBA modifies OVX-associated changes. In the context of OVX, CBA administraton produced larger metabolic and cellular effects; which we speculate may reflect a protective role of estrogen against CBA-mediated adipose tissue injury in female SIV-infected macaques.

Project description:HIV-associated neurocognitive disorder is prevalent despite wide-spread use of effective anti-retroviral therapy (ART). Alcohol use disorders (AUDs) exacerbate neurocognitive dysfunction in HIV+ patients. Previously we have shown that chronic binge alcohol administration (CBA, 13 – 14 g EtOH/kg/wk) starting 3 months prior to simian immunodeficiency virus (SIV) infection in rhesus macaques unmasks behavioral deficits. The underlying mechanisms of neurocognitive alterations due to alcohol and SIV are not known. The aim of this study was to explore the alterations in hippocampal gene expression of CBA administered, SIV-infected (CBA/SIV+; N=2) macaques and isocaloric sucrose administered, SIV-infected (SUC/SIV+; N=2) macaques in contrast to uninfected (SIV-; N=2) macaques. Transcriptomes of hippocampal samples dissected from brains obtained at necropsy (16 months post-SIV inoculation) were analyzed using Illumina Custom algorithm to determine differentially expressed genes (p-value filter of ≤ 0.05; either ≥ 1.3 fold change or ≤ 0.76 fold change) between SUC/SIV+ and SIV-, CBA/SIV+ and SIV-, and CBA/SIV+ and SUC/SIV+. We used Gene Codis to determine enrichment of specific Gene Ontology Biological Processes from both the SUC/SIV+ and CBA/SIV+ gene lists. Gene Codis analysis revealed over-representation of genes involved in neurodevelopment, neurotransmission, interferon-signaling, and antigen presentation in the CBA/SIV+ group. Further analysis of differentially expressed genes between SIV- and CBA/SIV+ showed predominantly up-regulation of immune function genes and down-regulation of nervous system development and synaptic transmission genes in CBA/SIV+ animals. These findings provide insight into the potential mechanisms by which CBA may enhance neurobehavioral deficits.
