MicroRNAs help control HIV life cycle
Published in AIDS Weekly, July 13th, 2009
Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells. In particular, miR29 plays a key role in controlling the HIV life cycle. The study suggests that HIV may have co-opted this cellular defense mechanism to help the virus hide from the immune system and antiviral drugs. The research was published in the journal Molecular Cell.
Tariq Rana, Ph.D., director of the Program for RNA Biology at Burnham, and colleagues, found that the microRNA miR29 suppresses translation of the HIV-1 genome by transporting the HIV mRNA...
