Studies have shown that the NRF-2 /HO-1 pathway participates in myocardial ischemic reperfusion injury (MI/R) and that Geniposide (GEN) could protect the myocardial against MI/R. This study aims to examine the protective effects of GEN on MI/R in diabetic rats and further explore the possible mechanism of action. During MI/R in rats, NRF-2 /HO-1signals changed significantly including NRF-2 and HO-1up-regulation, resulting in heart dysfuction, histological damage and increasing oxidative stress and cell apoptosis. Treatment with GEN can significantly improve the general condition and heart function in diabetic rats with decreasing the expression of cTnI, CK-MB, blood glucose, MDA, ROS, cell apoptosis and pathological damage in MI/R. In addition, GEN precondition can also significantly increase the weight of rats and the activity of SOD, CAT and GPx with up-regulating the expression of NRF-2 and HO-1 in MI/R. This study implied that Geniposide has a protective effect on myocardial ischemia reperfusion injury in diabetic rats, and its mechanism is associated with activating NRF2/HO-1 signaling pathway to suppress oxidative stress.

Type 2 diabetes mellitus (T2DM) adversely affects various organs, including the brain and its blood barrier. In addition to the brain, hyperglycemia damages the testes. The testes possess blood-tissue barriers that share common characteristics and proteins with the blood-brain barrier (BBB), including breast cancer-resistant protein (BCRP).

The chronic inflammation and matrix metalloprotease (MMP)-induced tissue degradation significantly disrupt re-epithelization and delay the healing process of diabetic wounds. To address these issues, we produced nanofibrils from Antheraea pernyi (Ap) silk fibers via a facile and green treatment of swelling and shearing. The integrin receptors on the cytomembrane could specifically bind to the Ap nanofibrils (ApNFs) due to their inherent Arg-Gly-Asp (RGD) motifs, which activated platelets to accelerate coagulation and promoted fibroblast migration, adhesion and spreading.

Objectives: This study aimed to determine the effect of 8-week high-intensity interval training (HIIT) on oxidative stress and apoptosis in the hippocampus of male rats with type 2 diabetes (T2D). The study focused on examining the role of proliferator-activated receptor gamma co-activator 1α (PGC1α)/Kelch-like ECH-associated protein Keap1/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway.
Materials And Methods: Twenty-eight 8-week-old Wistar rats were randomly assigned to one of four groups (n=7): control (Con), type 2 diabetes (T2D), exercise (Ex), and exercise + type 2 diabetes (Ex+T2D).

Objectives: While ketone bodies are not the main heart fuel, exercise may increase their uptake. Objectives: This study aimed to investigate the effect of 6-week endurance training and Pyruvate dehydrogenase kinase 4 )PDK4( inhibition on ketone bodies metabolism in the heart of diabetic rats with emphasis on the role of Peroxisome proliferator-activated receptor-gamma coactivator PGC-1alpha (PGC-1α).
Materials And Methods: Sixty male Wistar rats were divided into eight groups: healthy control group (CONT), endurance training group (TRA), diabetic group (DM), DM + EX group, Dichloroacetate (DCA) group, DM + DCA group, TRA + DCA group, and DM + TRA + DCA group.
