Published in advance in Nucleic Acids Research this week, the University of Texas Southwestern Medical Center's Scott Younger and David Corey present their computational method to identify potential miRNA target sites within gene promoters. The researchers tested 10 candidate miRNAs, which are predicted to target the human progesterone receptor gene promoter, for their ability to modulate gene expression, and found evidence of chromatin-level silencing by an RNA mimic.
