Cellular survival after radiation exposure depends on the specific protein behavior – News-Medical.Net

Exposure to radiation can wreak indiscriminate havoc on cells, tissues, and organs. Curiously, however, some tissues are more vulnerable to radiation damage than others.
Scientists have known these differences involve the protein p53, a well-studied tumor-suppressor protein that initiates a cell’s auto-destruct programs. Yet, levels of this sentinel protein are often similar in tissues with vastly different sensitivities to radiation, posing the question: How is p53 involved?
A new study by researchers…
