Accentuated skeletal muscle loss in patients with non-communicable diseases such as Chronic Obstructive Pulmonary Disease (COPD) is a strong independent predictor of hospitalisation and mortality. Exercise training remains the most powerful intervention for reversing in part muscle wasting in these patients. However, a proportion of patients experience limited clinical outcomes, even when exercise training has been adequately performed.
As skeletal muscle function and regenerative capacity are facilitated by a population of muscle stem cells (satellite cells) the project will investigate (1) biochemical and biological effect of exercise training on promoting satellite cell proliferation and muscle hypertrophy and (2) the pathological effect of COPD on satellite cell function and muscle hypertrophy.
This project is multi-disciplinary including physiological, molecular biological and cellular techniques, image analysis, cell culture, immunostaining and gene expression. The project benefits from access to a Biobank of human skeletal muscle samples of well-characterized cohort of cachectic and non-cachectic patients and in vitro facilities to study human satellite cells. Additionally the project will benefit form an experience supervisory team including Dr. Davina C M Simoes, Prof. Steve Todryk and Prof Mihalis Panagiotidis.
