Reconnaissance of candidate genes involved in human immunodeficiency virus (HIV) pathogenesis and targeted by antiretroviral therapy

The expression levels of many genes change after treatment of human immunodeficiency virus (HIV)-infected subjects by antiretroviral drugs. High-throughput analysis of tremendous datasets led to the discovery of genes that are implicated in the treatment pathways. In this study, we performed a gene-enrichment analysis after determining the differentially expressed genes (DEGs) between untreated HIV-positive and HIV-negative subjects and also between treated HIV-positive subjects with antiretroviral therapy (ART; who receiving nucleoside reverse transcriptase inhibitor-based ART) and untreated HIV-positive cases in the peripheral blood mononuclear cells (PBMCs), adipose, and muscle tissues. In sum, the genes that activate inflammatory, immune response, proliferation, metabolism, and viral involvement pathways have different expression patterns in the untreated HIV-positive subjects and treated HIV-positive cases. Moreover, the expression levels of the genes including ACLY, ALDH18A1, HADHA, and YARS in the PBMCs tissue and HBEGF, PKN3, DEGS2, and EDN3 in the fat tissue were found to be different in the HIV-infected patients, which can be considered as new biomarkers for HIV infection.
