Deficient DNA Repair Capacity Associated With Increased Risk Of Breast Cancer

...s analyzed cell lines generated from blood samples taken from pairs of sisters in which one sister had been diagnosed with breast cancer and the other had not. They found that DNA repair capacity was lower in breast cancer patients than in the control subjects. Deficient DNA repair capacity was associated...

Neuronal 'traffic jam' marks early Alzheimer's disease
