Identification of human microRNA-like sequences embedded within the protein-encoding genes of the human immunodeficiency virus.

ABSTRACT:

Background

MicroRNAs (miRNAs) are highly conserved, short (18-22 nts), non-coding RNA molecules that regulate gene expression by binding to the 3' untranslated regions (3'UTRs) of mRNAs. While numerous cellular microRNAs have been associated with the progression of various diseases including cancer, miRNAs associated with retroviruses have not been well characterized. Herein we report identification of microRNA-like sequences in coding regions of several HIV-1 genomes.

Results

Based on our earlier proteomics and bioinformatics studies, we have identified 8 cellular miRNAs that are predicted to bind to the mRNAs of multiple proteins that are dysregulated during HIV-infection of CD4+ T-cells in vitro. In silico analysis of the full length and mature sequences of these 8 miRNAs
