My research group is interested in the role of epigenetic mechanisms in musculoskeletal tissues homeostasis, specifically the aspects related to decline of muscle, cartilage and tendon function and regenerative potential. We use in vitro and in vivo model systems to study the functional aspects of dysregulation of epigenetic mechanisms during ageing and disease. Our aim is to establish novel biomarkers and therapeutics against age-related disorders of the musculoskeletal tissues. More recently, we have been investigating microRNAs as potential therapeutic for muscle wasting during cancer cachexia and amyotrophic lateral sclerosis.
Our research is funded by BBSRC, Dunhill Medical Trust, Orthopaedic Research UK, CIMA, IRC.

microRNAs as potential therapeutics for muscle wasting in ageing and disease
Irreversible muscle loss due to ageing (sarcopenia) or disease such as cancer (cachexia) or critical illness such as sepsis, is a major socio-economic and healthcare burden that will increase with our ageing population and in the light of the current health care challenges. Muscle loss leads to frailty, hospitalisation and is prognostic of morbidity and mortality. Patients, e.g. cancer or critically ill, with lower muscle mass show worse recovery and even response to the therapy. Despite progress in understanding muscle loss, no effective therapies exist. Exercise can delay, but not reverse, muscle loss in a small group of patients.
Based on our work demonstrating that during ageing and disease, microRNAs levels are altered and microRNAs can be modified to regulate alternative set of genes and inhibiting pathogenic miRs improves muscle size and strength in vivo, we hypothesise that imiR-based approcahes can provide an alternative, effective therapy against muscle loss.
The project will use a combination of discovery-driven omics and bioinformatics to characterise changes in microRNAs during muscle wasting. Functional studies in models of muscle loss will validate the crucial role of miRs in muscle wasting and provide evidence for the use of oxi-miR inhibitors to improve muscle mass and strength.
