IL1B and diabetic cardiomyopathy: Similarly, mRNA expression of caspase-1 and IL-1b was significantly reduced and miR-214-3p expression was elevated in mouse hearts following MIAT knockdown or caspase-1 inhibitor application, suggesting that MIAT may affect cellular pyroptosis in diabetic cardiomyopathy by targeting miR-214-3p to regulate the expression of caspase-1 and IL-1b process.
