In addition, CNCbl significantly decreased both apoptosis and necrosis in the hippocampus CA1 ( <0.01). CNCbl improves memory impairment following ischemia injury by decreasing neuronal cell death via its antioxidant properties.

Physical exercise has emerged as an effective therapy to mitigate cardiac remodelling in diabetic cardiomyopathy (DCM). The results of our previous studies revealed mammalian sterile 20-like kinase 1 (Mst1) is a key regulator of the progression of DCM. However, the precise molecular mechanism of physical exercise-induced cardiac protection and its association with Mst1 inhibition remain unclear. Wildtype and Mst1 transgenic mice were challenged with streptozotocin (STZ) to induce experimental diabetes and were divided into sedentary and exercise groups. The DCM phenotype was evaluated by echocardiography, Masson's trichrome staining, TUNEL and immunoblotting analyses. The exercise-regulated miRNAs targeting Mst1 were predicted by bioinformatic analysis and later confirmed by RT-qPCR, immunoblotting, and dual-luciferase reporter assays. In addition, cultured neonatal mouse cardiomyocytes were subjected to simulate diabetes to elucidate the underlying mechanisms. Compared to the sedentary diabetic control, physical exercise inhibited Mst1 and alleviated cardiac remodelling in mice with DCM, as evidenced by decreases in the left ventricular end-systolic internal dimension (LVESD) and left ventricular end-diastolic internal dimension (LVEDD), increases in the left ventricular ejection fraction (LVEF) and left ventricular fracti
