Investigating the Dystrophin-Glycoprotein Complex to Protect Muscles from Wasting Conditions

Project Details

The dystrophin-glycoprotein complex (DGC) is a multi-protein structure required to maintain integrity of the muscle fibre membrane and to transmit force, by linking the actin cytoskeleton with the extracellular matrix. Importantly, we and others have shown the DGC also plays a critical role in the signalling mechanisms that maintain muscle homeostasis and membrane localisation of dystrophin is perturbed in muscles wasting because of cancer cachexia, sepsis, unloading, denervation and advanced ageing, which are all associated with low level, chronic inflammation.

Identifying therapeutic approaches to restore the DGC at the muscle fibre membrane is essential for improving clinical outcomes for patients whose muscles are wasting and seemingly unresponsive to other treatments.

This project will test the hypothesis that loss of DGC integrity at the fibre membrane is implicated in multiple wasting conditions and that post-translational modification modulates these DGC interactions to preserve and protect muscles in different muscle wasting states.
