Metastatic dissemination is the main cause of mortality in cancer patients. Highly motile and invasive cells appear at different stages of tumour evolution, disseminate from the primary site and give rise to the secondary tumours. These motile tumour-initiating cells have properties of stem cells and are generated by abnormal activation of embryonic genetic programs termed Epithelial-Mesenchymal Transitions (EMT).

When EMT programs are activated in primary carcinomas, the affected cells lose their epithelial polarity, acquire a motile mesenchymal phenotype and escape from the original tumour. Several proteins belonging to ZEB, SNAIL or TWIST transcription factors families have been characterised as master regulators of EMT (EMT-TFs). EMTs are reversible, and modulations in the expression and the activity of EMT-TFs result in flexible changes in tumour cell phenotype.

My research is focused on tumour cell plasticity and, in particular, on how EMT affects cytoskeletal remodelling, cell morphology and motility. I use cancer xenograft models in Zebrafish for studying cell migration and invasion (collaboration with Dr Jonathan McDearmid, Leicester) (Fig.1). 

Figure 1

Gross alterations in gene expression patterns are molecular basis of EMT; and proteins of the S100 family are important EMT markers. I continue my research on the effect of S100 proteins on myosin dynamics and their implication in the development of EMT programs (Fig.2).

In collaboration with Dr Eugene Tulchinsky, I initiated a new project investigating the role of the receptor tyrosine kinase AXL in bladder cancer. AXL is activated in in vitro EMT models and overexpressed in EMT/stem-like subtypes of some cancers including transitional cell carcinoma of the bladder. Downregulation of AXL in bladder cancer cells significantly decreases cell invasion highlighting AXL as a potential therapeutic target molecule in bladder cancer (Fig.3).

Congratulations from the LCRC to Bethan Rogoyski and Aleksandra Bzura.

Bethan won best oral presentation at the AMS Midlands Academy of Medical Sciences Festival held on 27th March 2019 for her presentation on "Redeployment: The potential of repurposed drugs in preventing mesothelioma".

Aleks won the University PGR poster fair competition on 18th March 2019 for her poster entitled "New hope for treating mesothelioma cancer using PARP inhibitors".

Also, a huge well done to Grandezza Aburido who was in the semi-finals of the PGR poster fair.  


Congratulations to Noura Alibrahim who passed her PhD viva recently.  Well done!


In a recent exercise undertaken by the NCRI’s Clinical and Translational Radiotherapy Research Working Group (CTRad) Leicester was rated as internationally competitive/leading in the Radiation Biology Research domain, one of just four centres in the UK to achieve this rating in that domain.
