This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. My main research focus during the past year and since joining the COBRE has been to study the pathophysiology of abnormal cardiac excitation-contraction (E-C) coupling and impaired cell survival/signaling in diabetes, hypertension, obesity, and aging. My work focuses on whole heart, single ventricular myocyte function, cell culture, intracellular calcium homeostasis and various subcellular signaling pathways related to nitric oxide and various kinds of cell stress. Cellular physiology combined with molecular biology, transgene and gene transfer techniques are used to understand the mechanisms of action under these disease states.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。在过去的一年里，我的主要研究重点是自从加入COBRE以来，一直在研究糖尿病，高血压，肥胖和衰老中异常心脏兴奋-收缩（E-C）偶联和受损细胞存活/信号传导的病理生理学。我的工作主要集中在整个心脏，单个心室肌细胞功能，细胞培养，细胞内钙稳态和各种亚细胞信号通路相关的一氧化氮和各种细胞应激。细胞生理学结合分子生物学、转基因和基因转移技术用于了解这些疾病状态下的作用机制。
