“…In diabetic mice, both circulating and myocardial H 2 S levels are inhibited, while H 2 S mitigates diabetes-induced cardiomyopathy in these mice (Barr et al, 2015). Similarly, STZ-induced rats displayed a conspicuous reduction in cardiac H 2 S concentration (Palamarchuk et al, 2020). These results underscored the crucial role of endogenous H 2 S in DCM progression.…”
