Qian Chen, PhD
Dr. Qian Chen is a Research Assistant Professor in the Department of Pathology, Microbiology,
Immunology and Forensic Medicine after two and half years of postdoctoral training
at PCOM. Dr. Chen currently collaborates with Dr. Young and has made substantial contributions
in sequestering NIH grant funding, authoring peer-reviewed publications/poster presentations
and training graduate/D.O. students. She received her PhD in Cardiology from the Xi'an
Jiao Tong University College of Medicine in 2001 in China. Dr. Chen is a member of
Neuroscience Society and Sigma Xi Scientific Research Society.
Dr Chen's research interest is to understand the pathological changes in vascular
endothelial dysfunction under various disease conditions, such as myocardial infarction,
stroke and diabetes. Because vascular endothelial dysfunction is one of earliest events
occurring in many diseases, the clarification of the related mechanisms can provide
a new strategy for treatment. Protein kinase C is very important for regulating vascular
endothelial function. However, the function and changes of different PKC isoforms
in different diseases are still unclear. Currently, she is conducting experiments
to understand the role of different PKC isoforms in regulating leukocyte-endothelium
interactions in vivo by using intravital microscopy. She is also planning to combine
intravital microscopy with measurement of free radicals to relate the oxidative stress
in leukocyte-endothelial interactions under pathological conditions, such as hyperglycemia.
