Jun Zhang, PhD
Instructor/Research
Dr. Jun Zhang's research focuses on free radicals produced by mitochondrial activity can damage cellular components and macromolecules, including lipids, proteins and DNA, leading to aging. Cardiolipin is a mitochondrial membrane phospholipid required for oxidative phosphorylation and mitochondrial biogenesis. In contrast to other phospholipids, the biological function of cardiolipin is determined by its acyl composition, which is dominated by linoleic acid in healthy metabolic tissues, such as heart, liver, and skeletal muscle. Oxidized cardiolipin serves as a new source of ROS, initiating a chain of events of oxidative stress and CL oxidation known as “CL peroxidation” which is implicated in the mitochondrial dysfunction of aging and age-related diseases. Our research work focuses on the molecular mechanisms of pathological cardiolipin remodeling and mitochondrial dysfunction in aging and the onset of aging-related diseases, including diabetes, obesity, cardiovascular diseases and neurodegenerative diseases. We are also uncovering the molecular regulation roles of mitochondrial function and mitochondrial phospholipids in several cellular processes, including autophagy, apoptosis, inflammation and innate immune response.
