Our current understanding of cellular signalling and disease is based on ensemble measurements over a cellular or molecular population. While these measurements have provided valuable information on the molecular circuitry required for cellular function, there is a lack of detail on the spatio-temporal dynamics of signal initiation and propagation at the single molecule and single cellular level.

While these measurements have provided valuable information on the molecular circuitry required for cellular function, there is a lack of detail on the spatio-temporal dynamics of signal initiation and propagation at the single molecule and single cellular level. Single particle (molecule or cell) approaches offer the advantage of being able to detect individual processes including rare events that would be lost in an ensemble measurement. Moreover single particle approaches provide dynamic-kinetic information that does not rely on synchronising a population of molecules or cells. In this proposal we aim to build on our combined expertise in EGF-EGFR signalling, biophysics, biosensors, quantum dot nanotechnology and single molecule spectroscopy to learn more about how EGFR cellular signalling works and how it is impaired in cancer. This project will provide basic information that could lead to the design of more effective drugs directed agaisnt this therapeutic target.Read moreRead less

Summary
The prevalence of cancer and, in particular, cancer that spreads throughout the body has risen over the past twenty years in the human population and causes significant human mortality. A correlation between some of a cancerous cell's surface componentary and the ability of this cell to spread throughout the body has been established. This research project will provide a range of chemical entities (probes) that will intervene in this spreading process (metastasis).

A correlation between some of a cancerous cell's surface componentary and the ability of this cell to spread throughout the body has been established. This research project will provide a range of chemical entities (probes) that will intervene in this spreading process (metastasis). These probes will be the basis for a drug discovery programme that targets a particular aspect of the spreading process. Through molecular modelling, drug candidate synthesis and evaluation of these compounds in relevant test tube (in vitro) assays it is envisaged that a number of candidate compounds will then be evaluated in an animal model (in vivo assay). The technology to be used in this project is comparable to that which we used in the discovery of the recently approved influenza drug, Relenza?.Read moreRead less

Summary
The prevalence of the disease Cholera still causes significant human mortality, in particular in underdevloped countries. The process that enables the cholera toxin to cause signficant damage is now partly understood. This research project will provide a range of chemical entities (probes) that have the potential of intervening in this process .

These probes will be the basis for a drug discovery programme that targets toxin binding. Through molecular modelling based on protein structural information, drug candidate synthesis and evaluation of these compounds in relevant test tube (in vitro) assays it is envisaged that a number of candidate compounds will be then further optimised for eventual pre-clinical investigation.
