QMUL Directory


As Lead for the Centre for Molecular Oncology, I oversee a range of research themes from solid tumour genomics and bioinformatics, molecular diagnostics and biological therapies to, more recently, DNA repair and genome stability.

We are particularly focussed on pancreatic, lung, prostate and ovarian cancers as areas of high unmet clinical need, working closely with colleagues in oncology at Barts Cancer Centre to translate discoveries into patient benefit.

 

Research Details

The current research projects within my group originate from our initial identification of LIMD1 as a specific pRB (retinoblastoma protein) binding partner (Sharp TV et al. PNAS 2004).  LIMD1 is on chromosome 3p21.3, often deleted in epithelial cancers. We have also shown that LIMD1 is a bona fide lung cancer tumour suppressor (Sharp TV et al PNAS 2008) and also that loss of LIMD1 expression correlates with poor patient prognosis and decreased survival with respect to breast cancer (Spendlove et al 2008).


The full molecular characterization of this novel tumour suppressor is therefore the main focus of my group’s continued research. By understanding the function(s) of LIMD1 and indeed its family member proteins (Ajuba and WTIP); we can begin to understand how loss of this important tumour suppressor(s) contributes to disease pathogenesis and specifically tumorigenesis.

PhD Studentships within the Sharp Group

Candidates interested in joining the lab to work in this research area can contact Dr Sharp by sending an email to t.sharp@qmul.ac.uk.

Currently positions are only available to self-funded students. QMUL Principal's Postgraduate Research Studentships are available to international students of any nationality and provide funding for up to 3 years of PhD study.

For more information on studentships for both home and international students, please visit here.

Profile

I obtained my PhD from St. Georges, University of London. After two postdoctoral positions in The Netherlands and USA, I retuned to take up a Senior Research Fellow position at the Institute of Cancer Research in London and then UCL. I then moved to the University of Nottingham to set up my independent research group in 2005. From there I relocated to BCI. My group studies the role of the LIM domain family of adaptor proteins and their role in regulating microRNA mediates gene silencing and the hypoxic response and how deregulation of these proteins and pathways contribute to disease states including cancer.
