Yang et al (40) report that KCNQ1OT1 is highly expressed in patients with diabetic cardiomyopathy and that silencing KCNQ1OT1 successfully inhibits cell apoptosis by increasing the expression of miR-214-3p and then downregulating its target gene by acting as a ceRNA in vivo. The gene discussed is KCNQ1OT1; the disease is diabetic cardiomyopathy.
