One of the most universal characteristics of cancer cells is their immortality. We study the mechanisms by which tumour cells are immortal and normal cells are mortal. Over 95% of all types of human cancers exhibit the enzyme telomerase, absent in normal cells in the body. Telomeres, nucleoprotein complexes at the ends of chromosomes, are essential for chromosome protection and genomic stability. Their progressive shortening as the organism ages leads to ageing. If telomeres are altered, the regenerative capacity of adult stem cells is maimed.
Our research focuses on:
Mouse models to validate telomeres and telomerase as therapeutic targets for cancer and age-related diseases.
Interplay between telomeres and DNA repair pathways.
Role and regulation of non-coding telomeric RNAs (TERRA).
Telomerase gene therapy in telomere syndromes and age-related diseases.
Role of telomerase and telomeres in:
adult stem cell biology
nuclear reprogramming of differentiated cells to induced pluripotent stem cells (iPS cells).
