LIMK1 and congestive heart failure: To further investigate the effect of miR-93 targeting LIMK1 gene on cardiomyocyte AI in rats with CHF, the results showed that in contrast to the miR-93 mimics + OE-NC group, the cardiomyocyte AI in the miR-93 mimics + OE-LIMK1 group was obviously increased (P < 0.05; Figure 8A–8B).
