Insulin-like growth factor I (IGF-I) is an important survival growth factor that has been shown to inhibit apoptosis, but the effects of IGF-I on apoptotic signaling remain largely unknown. To investigate IGF-I actions on apoptosis of H9C2 cardiac muscle cells, we have defined the effects of IGF-I on Bcl-2, Bax, caspase 3, DNA fragmentation, and cell survival. The abundance of Bcl-2 and Bax was...
Excess catecholamine levels are suggested to be cardiotoxic and to underlie stress-induced heart failure. The cardiotoxic effects of norepinephrine and epinephrine are well recognized. However, although cardiac and circulating dopamine levels are also increased in stress cardiomyopathy patients, knowledge regarding putative toxic effects of excess dopamine levels on cardiomyocytes is scarce. We...
Aspalathin (ASP) can protect H9c2 cardiomyocytes against high glucose (HG)-induced shifts in myocardial substrate preference, oxidative stress, and apoptosis. The protective mechanism of ASP remains unknown. However, as one of possible, it is well known that phytochemical flavonoids reduce oxidative stress via nuclear factor (erythroid-derived 2)-like 2 (Nrf2) activation resulting in up-regulat...
Cardiovascular incidences are markedly higher in men than in pre-menstrual women. However, this advantage in women declines with aging and therefore can be correlated with the sex hormone 17β-Estradiol (E2) which is reported to protect heart cells by acting though estrogen receptors (ERs). In this study we have determined the effect of E2/ERβ against ISO induced cellular hypertrophy in H9c2 car...
miRNAs have been implicated in processing of cardiac hypoxia/reoxygenation (H/R)-induced injury. Recent studies demonstrated that miR-19a might provide a potential cardioprotective effect on myocardial disease. However, the effect of miR-19a in regulating myocardial ischemic injury has not been previously addressed. The present study was to investigate the effect of miR-19a on myocardial ischem...
Doxorubicin (Dox) has been used for more than four decades to treat cancer, particularly solid tumours and haematological malignancies. However, the administration of this drug is a matter of concern in the clinical community, since Dox therapy is commonly associated with dose-dependent cardiotoxicity. Attempts at alleviating drug generated cardiac damage using naturally occurring compounds wit...
Naoxintong (NXT) is an empirical formula based on the principle of traditional Chinese medicine, which has been approved by China Food and Drug Administration (CFDA) and is widely used for treatment of patients with cerebrovascular and cardiovascular diseases in China. The aim of this study is to investigate the protective mechanism of NXT on H9c2 cells (cardiogenic cell line) in response to H2...
