Description

We analyzed miRNA profiles in normal liver and identified miR-709, a highly abundant miRNA in this tissue. Through microarray analysis, gene targets were identified. Thirty-six genes were significantly down-regulated >2-fold in the miR-709-treated relative to the control group, and at least three of them, including Ras-related protein 11b (Rab11b), phosphatidylcholine transfer protein (Pctp), and carboxylesterase 1g (Ces1g), are direct targets. miR-709 regulates genes implicated in cytoskeleton organization, extracellular matrix attachment, cell proliferation and fatty acid metabolism, suggesting a coordinated response during cell division, when cytoskeleton remodeling requires substantial changes in gene expression.
