Abstract
My research focus is on studying the mechanisms of cardiomyocyte apoptosis and how estrogen protects the heart from ischemia-related injury.

Ischemic heart disease (IHD) is the leading cause of morbidity and mortality in the United States. It has been known that women have a significantly lower incidence of IHD until menopause, after which point the incidence accelerates to equal that in men. Furthermore, a better prognosis is observed in women than men following acute coronary syndrome.

Although the ability of hormone replacement therapy to reduce cardiovascular mortality is currently controversial, it is clear that premenopausal women are better protected from IHD. While the mechanism behind this observation is poorly understood, overwhelming data from studies of various molecular, cellular, and animal models collectively implicate estrogen to have beneficial cardiovascular effects.

After a period of prolonged ischemia or sudden reperfusion, the function of the heart can be compromised by loss of cardiomyocytes through a death process of apoptosis. Estrogen is anti-apoptotic in many cell types, including cardiomyocytes. However, details behind the estrogen-driven protection from apoptosis are not clear.

In our previous work, we have shown that cytoprotective effects of estrogen involve inhibition of a stress-induced kinase, p38alpha, and activation of the pro-survival isoform, p38beta. This, in turn, reduces mitochondrial generation of the reactive oxygen species (ROS), a known trigger of apoptosis. However, it remains unclear how the p38 kinases affect the death process initiated by ROS. An attractive downstream target of the kinase is p53, a well-known mediator of apoptosis.

We propose that the cytoprotective actions of estrogen involve regulation of p53 via p38. Our goal is to investigate the specific interaction between the two p38 isoforms and p53 in the estrogen-mediated protection of cardiomyocytes following ischemia-related injury, using a comprehensive approach of molecular, cellular and whole-animal models.
