Research Topic

We investigate cellular signals that regulate the functions of the heart and vessels. In particular, our research focuses on the study of calcium microdomains and how their perturbation in cardiac muscle and smooth muscle often results in cardiac and vascular wall diseases, leading cause of death in the modern world. Currently, we are studying the newly discovered intracellular calcium sensors, Stromal Interaction Proteins (STIM1 and STIM2) which are crucial components of these cellular microdomains. We employ high definition confocal microscopy, electrophysiology, and isolated heart technique to characterize the calcium signaling generated in the microdomains and how this travel into the nucleus to start a pathological gene transcription program. We also use animal models of cardiovascular diseases to mimic the human disease process and the calcium signal disarray that undermine such disease in order to explore new therapeutic strategies against cardiovascular disorders.

Postdoc Opportunities

We are always seeking enthusiastic, self-motivated candidates who are excited to tackle a biologically-intriguing and medically-important disease and be a collaborative member of our laboratory. Ideal candidates will have a MD and/or PhD in biology, biochemistry, chemistry, or related fields. Experience in molecular biology, live cell imaging, and/or animals surgery desired. Excellent English written and spoken skills are necessary.

Graduate Students Opportunities

We are keen to hear from talented students wishing to pursue graduate studies in my lab. Future PhD projects involve researching molecular basis of cardiac diseases and hypertension. Interested individuals should email Prof. Mancarella outlining any research experience and details of classes taken during their undergraduate degree. Potential graduate students can apply through the UTHSC PhD program. Students enrolled in the UTHSC PhD program should also contact Prof Mancarella if they wish to undertake a lab rotation.
