BACKGROUND: The polyphenol resveratrol (Rev) has been reported to exhibit
cardioprotective effects, such as inhibition of TAC (transverse aortic
constriction) or isoprenaline (ISO)-induced hypertrophy. MicroRNA-155 (miR-155)
was found to be decreased in hypertrophic myocardium, which could be further
reduced by pretreatment of Rev. The study was designed to investigate the
molecular effects of miR-155 on cardiac hypertrophy, focusing on the role of
breast cancer type 1 susceptibility protein (BRCA1). METHODS AND RESULTS: We
demonstrated that Rev alleviated severity of hypertrophic myocardium in a mice
model of cardiac hypertrophy by TAC treatment. Down-regulation of miR-155 was
observed in pressure overload- or ISO-induced hypertrophic cardiomyoctyes.
Interestingly, administration of Rev substantially attenuated miR-155 level in
cardiomyocytes. In agreement with its miR-155 reducing effect, Rev relieved
cardiac hypertrophy and restored cardiac function by activation of BRCA1 in
cardiomyoctyes. Our results further revealed that forkhead box O3a (FoxO3a) was a
miR-155 target in the heart. And miR-155 directly repressed FoxO3a, whose
expression was mitigated in miR-155 agomir and mimic treatment in vivo and
in vitro. CONCLUSIONS: We conclude that BRCA1 inactivation can increase
expression of miR-155, contributing to cardiac hypertrophy. And Rev produces
their beneficial effects partially by down-regulating miR-155 expression, which
might be a novel strategy for treatment of cardiac hypertrophy.
