BMAL1 and myocardial ischemia: The above studies indicate that cardiomyocyte death is closely related to BMAL1, which is involved in regulating the expression of cardiomyocyte death-related proteins, and that understanding the intrinsic molecular mechanisms of cardiomyocyte death may reduce the degree of myocardial injury after myocardial ischemia and improve its prognosis (Table 1).
