Ahmed Lab

We are primarily interested in the role of Wnt mediated signal transduction and gene transcription in stem cells and in cancer. Our research hypothesis is that cell electrical potential is a key regulator of gene transcription. A translational objective is to convert the mechanistic knowledge about Wnt signalling into regenerative medicine and cancer therapies and biomarkers.

Wnts are conserved, cysteine-rich secreted protein ligands, acting as close-range signalling molecules. Wnt signal transduction pathway, with free intracellular calcium ([Ca2+]i) and β-catenin, a 92 kDa transcription factor co-activator as two key intracellular transducers, is critical in stem cell homeostasis and in diseases like cancers (e.g. colon, breast, prostate).

We have shown that Wnt ligands control cell membrane electrical potential (Ashmore, et al, 2019). This discovery of a novel mechanism of Wnt signal transduction underpins our approach towards identifying membrane potential regulating compounds (MPRCs) as inhibitors of Wnt signalling that could be developed as safe and cost-effective therapy for cancers.

We also employ quantitative expression of Wnt transcription targets in human tissue, combined artificial intelligence techniques, to develop robust biomarkers for diagnosis and prognostication of carcinomas and other rare diseases.

Our partners

We collaborate with pathologists (Prof. Rui Henrique, University of Porto), clinicians (Mr A Muneer, UCLH and Mr N Johal, GOSH) and scientists (Dr C Thrasivoulou, Prof. J Ashmore UCL and Prof. C Fry, University of Bristol) and experts in artificial intelligence (Prof. K Ahmad, Trinity College, Dublin) on various projects. We also collaborate with clinicians around the world including Nigeria, Germany, India, Pakistan and USA. We also collaborate with SME’s like Sophion (Denmark), manufacturers of automated patch clamp.
