The role of proteostasis imbalance in the pathogenesis of Chronic Obstructive Lung Disease (COPD):

Proteostasis regulates the functional properties of the proteome. Derailed proteostasis leads to protein misfolding and aggregation that is the underlying origin of many devastating human diseases including COPD. A molecular chaperone named valosin containing protein (VCP) plays a critical role in coordinating the proteostasis machinery which mediates protein degradation and the processing of protein aggregates. Our structural and functional studies have shown that VCP plays a critical role in the maintenance of proteostasis by facilitating proteasoma degradation and aggresome formation. We are currently investigating the mechanism underlying the disruption in the biological function of VCP which occurs in the lungs of COPD patients as a result of exposure to cigarette smoke, and smoke components including cadmium. We believe this research should contribute to the development of novel therapeutic strategies for the treatment of COPO.
