SIRT6‑specific inhibitor OSS‑128167 exacerbates diabetic cardiomyopathy by aggravating inflammation and oxidative stress.

ABSTRACT: Diabetic cardiomyopathy (DCM) is a serious complication of diabetes, which importantly contributes to the increased mortality of patients with diabetes. The development of DCM is accompanied by numerous pathological mechanisms, including oxidative stress and chronic inflammation. Accordingly, the present study aimed to determine the effects of the sirtuin 6 (SIRT6) inhibitor OSS‑128167 on DCM using a mouse model of streptozotocin (STZ)‑induced diabetes and high glucose (HG)‑treated cardiomyocytes. C57BL/6 mice were intraperitoneally injected with STZ for 5 days to simulate the diabetic cardiomyopathy model. Mice with STZ‑induced diabetes (STZ‑DM1) were orally administered OSS‑128167 (20 or 50 mg/kg) through gavage every other day. The expression of SIRT6 in myocardial tissue was detected u
