Cornell researchers identify a weak link in cancer cell armour

The seeming invincibility of cancerous tumours may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves. Researchers at the Cornell University College of Veterinary Medicine have discovered that inactivation of a DNA repair gene called Hus1 efficiently kills cells lacking p53 - a gene mutated in the majority of human cancers...
