Xi-Long Zheng is a tenured Professor in the Department of Biochemistry and Molecular Biology and Department of Physiology and Pharmacology at the Cumming School of Medicine, University of Calgary. He holds additional appointments as a Member of the Libin Cardiovascular Institute and Associate Member of both the Snyder Institute for Chronic Diseases and Arnie Charbonneau Cancer Institute. His research focuses on vascular smooth muscle biology and its role in cardiovascular diseases.
- Doctor of Medicine, Hunan Medical University (1986)
- M.S. in Pharmacology, Hunan Medical University (1989)
- Doctor of Philosophy in Pharmacology, University of Calgary (1997)
Dr. Zheng's research centers on vascular smooth muscle cell differentiation, proliferation, and phenotypic switching in vascular diseases. His laboratory investigates mechanisms of vascular smooth muscle dedifferentiation in atherosclerosis, abdominal aortic aneurysms, and vascular stiffness. Current work explores ferroptosis, epigenetic regulation (particularly BRD4), and PCSK9 functions in vascular pathologies. His studies integrate molecular, cellular, and in vivo approaches to identify novel therapeutic targets for cardiovascular diseases.
Analysis of his recent publications reveals strong emphasis on cell death mechanisms (ferroptosis, cuproptosis), epigenetic regulation, lipid metabolism, and immune-vascular interactions in atherosclerosis. His work demonstrates increasing focus on translational applications targeting vascular smooth muscle phenotypic switching and plaque stability.

Dr. Zheng serves on grant panels for Canadian Institutes of Health Research and Heart and Stroke Foundation of Canada. He is an editorial board member for Biochemical Journal and other scholarly publications. His laboratory receives funding from CIHR and NSERC for projects including smooth muscle PCSK9 in abdominal aortic aneurysm pathogenesis, smooth muscle autophagy in vascular aging, and epigenetic regulation of smooth muscle plasticity. The Zheng Lab investigates vascular smooth muscle functions across multiple organ systems including blood vessels, gastrointestinal tract, bladder, and uterus.
His research has established critical mechanisms in vascular smooth muscle differentiation and cell cycle regulation, contributing over 100 peer-reviewed publications in high-impact journals including PNAS, ATVB, Diabetologia, JBC, and Hypertension.
