Using a combination of methodologies, including mass spectrometry, protein biochemistry, cell biology, genetics, proteomics, and molecular biology, the Wells laboratory studies the role of PTMs (primarily O-glycosylation) in a variety of pathophysiological processes including cancer, diabetes, viral infection, neurological disorders, and congenital muscular dystrophy. Their research is aimed at increasing our understanding of how increased functional diversity leads to finer control of biological processes. The hope is that by understanding the role of PTMs, they will not only more accurately describe fundamental biological processes but will also elucidate novel therapeutic targets in disease states where these processes have become dysregulated.
