RAD51-mediated homologous recombination is a pro-tumour driver pathway - Oncogene Oncogene - RAD51-mediated homologous recombination is a pro-tumour driver pathway

Plot twist: homologous recombination actually promotes the development of cancer!

This discussion has been started in the hope that it will be useful, see the link:

Genome rearrangements induced by the stimulation of end-joining of DNA double strand breaks through multiple phosphorylation of MRE11 by the kinase PKB/AKT1 Abstract. Genetic instability is a major hazard threatening the fate of cells and ultimately of organisms. DNA double-strand break (DSB) is a highly toxic

The hyper-activation of DNA double-strand break repair by the AKT1/PKB oncogene generates genetic instability.
(A new role for the oncogene AKT1: the phosphorylation of MRE11).
