Enhanced skin cancer risk linked to defects in cellular aging controls

...gmentation. Researchers from Spain investigated the molecular mechanisms underlying skin cell telomere dysfunction using a mouse model of Xeroderma pigmentosum (XP), a disease in which patients have increased sensitivity to ultraviolet (UV) radiation. Their studies revealed that these mice have impaired skin ...

Skin Cancer Risk Increases With Ultraviolet-B Radiation Exposure

...s the commonest cause of skin cancer and is responsible for breaking DNA strands in exposed skin cells. Patients who have a condition called xeroderma pigmentosum are unable to repair these broken strands and hence are at increased risk of developing skin cancer. Li-E Wang, M.D., and Qingyi Wei, M.D., Ph.D., of ...
