The Role of HIV-1-Encoded microRNAs in Viral Replication.

ABSTRACT: microRNAs (miRNAs) are small non-coding RNAs (sncRNAs) that play an important role in the life cycle of human viruses. We sought to characterize human immunodeficiency virus 1 (HIV-1)-encoded miRNAs and determine their role in viral replication. Initially, a bioinformatic analysis was used to predict HIV-1-encoded miRNAs. Next, a representative number of these predicted sequences were verified using a miRNA microarray chip, reverse transcription PCR (RT-PCR), and the deep sequencing of RNA extracted from HIV-1-infected cells. Eight HIV-1-encoded sncRNA sequences conforming to the criteria that define miRNAs were identified in HIV-1-infected immortalized T cells and human primary CD4+ lymphocytes; five of the eight sequences have not been previously reported. Deep sequencing validated the p
