Brief career history
My group is using molecular and cellular approaches to understand the biology of the adhesion receptor dystroglycan. We are focussed on modulating dystroglycan signalling as a therapeutic route to treat Duchenne muscular dystrophy. We are also investigating the functions of dystroglycan in organising and stabilising the nuclear lamina, in cancer and in muscular dystrophies.
Regulation of dystroglycan function in muscular dystrophy and cancer
The laminin binding protein dystroglycan plays multiple roles in cell adhesion, signalling and membrane cytoskeleton stability. Perturbation of dystroglycan function underlies several muscular dystrophies and is also a secondary consequence of adenocarcinoma progression. Changes to the post-translational modification of dystroglycan are crucial in directing the associations, cellular localisation and ultimately degradation of dystroglycan. Our aim is to elucidate the mechanisms and consequences of these post-translational modifications in order to better understand dystroglycan function and to identify potential therapeutic targets for the treatment of muscular dystrophy or cancer.
We employ in vitro, in/ex vivo fish and mouse genetic models with clinically relevant archival tissue samples or immortalised cell lines. Dystroglycan function is dissected through the use of molecular cell biology approaches, and potential therapeutic targets are assessed in vitro and in vivo. Recently we have developed a novel therapeutic approach for the treatment of Duchenne muscular dystrophy using inhibitors of tyrosine phosphorylation and proteasomal degradation. Through the use of zebrafish screening and phenotypic analysis in mdx mice and human DMD myoblasts we are in the process of validating the potential for repurposed drugs as a precursor to initiating clinical trials. Physiological analysis is carried out I collaboration with Nic Wells at the RVC London.
In vitro models of prostate cancer have revealed a role for the post-translational proteolytic processing and nuclear targeting of dystroglycan. Current efforts are centred around characterising a role as part of the LINC complex in the inner nuclear membrane. These studies form part of an ongoing collaboration with Bulmaro Cisneros, CINVESTAV Mexico City.
