  Welcome to the p53Lab
The p53 lab is focusing on the development of new therapies, new diagnostics and new discoveries in the p53 pathway. 11 Million people living with cancer have specific mutations in the p53 gene leading to the production of a faulty p53 protein. This is half the cases of human cancer. In those that have an apparently normal p53 gene we believe that there are faults in the p53 pathway. We are using a variety of approaches to translate this extraordinary finding into clinical benefit. We work closely with many other groups both in Singapore and in the rest of the world to acheive this. We are using biochemical, biophysical, cell biological and genetic approaches in our work and offer an outstanding international training environment.
