Research description

Proteins destined for secretion or for insertion into the cell membrane are first folded within the endoplasmic reticulum. The process of protein folding can become defective in malignancy. When the level of misfolded proteins within the endoplasmic reticulum increases, the cell is said to experience “endoplasmic reticulum stress”.

We wish to understand the cellular consequences of endoplasmic reticulum stress; in particular its effects on tissue growth and cell survival. In doing so, we hope to identify targets for the development of novel therapies.
