Deficiency in p53 anti-tumor protein delays DNA repair after radiation

Researchers at Moffitt Cancer Center have found that a deficiency in an important anti-tumor protein, p53, can slow or delay DNA repair after radiation treatment. They suggest that this is because p53 regulates the expression ...
