Background: The mechanism of post-stroke cognitive impairment (PSCI) has not been explained. We aimed to investigate whether miR-let-7i participates in the PSCI and illuminates its underlying role in oxygen-glucose deprivation (OGD)-induced cell apoptosis.
Methods: Blood samples from 36 subjects with PSCI and 38 with post-stroke cognitive normality (Non-PSCI) were collected to evaluate the differential expression of miR-let-7 family members, using qRT-PCT analysis.
It has been well established that the mitochondrial ATP-sensitive potassium channel (mitoK(ATP)) opener, diazoxide, has protective effects on the heart and brain following ischemia/reperfusion injury. However, the mechanism of the neuroprotective effects of diazoxide remains unclear. This study highlights the anti-apoptotic effects of the drug, which are mediated by specific regulation of apoptosis-inducing factor (AIF) in the process of oxygen and glucose deprivation (OGD)-induced apoptosis in SH-SY5Y cells.
