Background: Calcium overload plays an important role in ischemia/reperfusion injury during ischemic brain damage and is mediated by calmodulin (CaM). However, the understanding of the regulatory mechanisms of CaM expression at the gene level is limited. The expression levels of miR-26b change significantly during ACI, and bioinformatic analyses predict that miR-26b would be a potential regulator of calmodulin (CALM1) mRNA. This study aimed to determine the expression of miR-26b and CaM in the plasma of patients with ACI and investigate the impact of miR-26b on CALM1 expression. Methods: CaM an...
