Dr Cunningham is an expert in the use of quantitative proteomics techniques to characterise regulatory phosphorylation events and protein-protein interactions that occur during cell signalling.

Qualifications

PhD Biochemistry, University College London

BSc (Hons) Biomedical Sciences, University of Wolverhampton

Biography

Dr Cunningham began her scientific career in the pharmaceutical company Rhone-Poulenc Rorer, investigating the pharmacokinetics of novel compounds. She was then awarded a CASE award from the MRC to carry out a collaborative PhD at the National Institute of Medical Research, Mill Hill and GlaxoSmithKline during which she used biophysical techniques to investigate the enzymatic properties of a Rho GTPase-activating protein. Dr Cunningham remained at GlaxoSmithKline to carry out her first post-doctoral research position, developing assays to identify inhibitors of protein-protein interactions.

In 2002, Dr Cunningham came to the University of Birmingham to work in Professor John Heath’s lab investigating Fibroblast Growth Factor signalling in cancer. She is currently a Lecturer within the Molecules, Cells, Signalling and Health theme in the School of Biosciences and her research interests focus around the use of quantitative proteomics techniques to characterise cellular signalling networks.

Postgraduate supervision

Dr Cunningham is currently supervising four PhD students.

Dr Cunningham is interested in supervising doctoral research students in the following areas:

  • Characterisation of aberrant signalling events in cancer cells reliant on growth factor signalling for survival.
  • Understanding signalling pathways downstream of the metabolic fibroblast growth factor, FGF21.
  • Regulation of cellular metabolism by LAR phosphatase.

Research

In response to extra- and intra- cellular signals, post-translational modifications (PTMs) on proteins can be altered to modulate protein activity, stability, spatial localisation and interaction with other molecules. Phosphorylation is a key PTM involved in the transduction of cell signalling events, and aberrant phosphorylation is linked to human disease. Thus, a better understanding of the global phosphorylation events within a cell during signalling is crucial. A major focus of Dr Cunningham’s research is to obtain a ‘systems-wide’ understanding of phosphorylation events in signalling networks. Using state of the art mass spectrometry based proteomic techniques allows for a global analysis of pathway components and the changes in phosphorylation of these components on perturbation of the system. Stable isotope labelling by amino acids in cell culture (SILAC) coupled to high resolution mass spectrometry is used to identify global or targeted phosphorylation events, and protein-protein interactions that occur during signalling. Bioinformatic, biochemical and molecular cell biology methods techniques are used to investigate the functional relevance of regulated proteins and specific phosphorylation events identified from these quantitative proteomic experiments.

Growth Factor Signalling

Activation of signal transduction by the receptor tyrosine kinases, fibroblast growth factor receptor (FGFR) and platelet-derived growth factor receptor (PDGFR), results in a cascade of protein-protein interactions that rely on the occurrence of specific phosphorylation events. Unregulated activation of these receptors can lead to oncogenic manifestations in certain cell types. Utilising recent phosphoproteomics data, current research involves the study of novel proteins downstream of FGFR and PDGFR, and their role in regulating biological processes involved in cancer.

LAR Phosphatase

Leukocyte common antigen-related protein (LAR) is a member of the LAR subfamily of receptor-like protein tyrosine phosphatases (RPTPs). Recent proteomic and phosphoproteomic studies have significantly expanded our understanding of signalling events and biological processes downstream of LAR. Current research is aimed at further characterising the role of LAR in regulating cell adhesion and cellular metabolism.
