Abstract
Human Immunodeficiency Virus type-1 (HIV-1) causes persistent and life-threatening infection, leading to progressive disease. MicroRNAs (miRNAs) are regulators of gene expression which can be found in circulating human blood samples. hsa-miR-29a-3p has been identified as a potential regulator of the Negative Regulatory Factor (Nef) gene from the HIV-1 viral genome. In this study, we aimed to compare the serum levels of hsa-miR-29a-3p with HIV-1 viral load in a substantial number of infected individuals. We collected serum samples from a total of 48 participants, including 36 untreated HIV-positive patients, and 12 HIV-negative individuals as a control group, matched for age and sex. The HIV-1 viral load in both the case and control groups was confirmed using qRT-PCR. Subsequent qRT-PCR analysis of circulating hsa-miR-29a-3p levels revealed lower miRNA expression in the groups with higher viral loads. A negative correlation (r = −0.58) was calculated between hsa-miR-29a-3p levels and HIV-1 viral load. These findings suggest that the expression level of hsa-miR-29a-3p may serve as an indicator of HIV-1 viral load in human serum samples. Additionally, this miR may hold promise as a potential tool for enhancing HIV-1 treatment strategies.
