description

COX-2 enhances insulin signaling. Finally, the relationship between COX-2 and the miRNAs was confirmed in NAS. Conclusions: COX-2 represses the expression of miRNAs implicated in the insulin signaling pathway via a PI3K/p300-dependent upregulation of DDX5, and by modulating the activity of the Drosha complex. Our study proposes a novel miRNA-dependent mechanism through which COX-2 promotes insulin signaling in liver cells.
