Plymouth Proteomics Research Group

Centre of expertise in proteomics for biomedical applications
membrane protease, syn/degradation
The Plymouth Proteomics Research Group develops and applies advanced proteomic technologies to study human diseases addressing various research questions ranging from biomarker diagnostics to disease mechanisms.
Our key research areas are aligned with following core themes
  • Infection, immunity and inflammation
  • Clinical neuroscience
  • Cancer
We are involved in various internal and external projects with our expertise. If you are interested in proteomics service or a research collaboration, please contact Dr Vikram Sharma 
 

Role of epigenetic modifications in cancer

Research work led by Dr Vikram Sharma focuses on post-translational modifications of histone/non-histone proteins and screening of novel epigenetic inhibitors in various cancer models.
Nucleosome, molecular model. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins. Histone protein: smooth molecular surface model; DNA: cartoon model.
