Why don't tumors respond to radiation?

A tightly controlled system of checks and balances ensures that a powerful tumor suppressor called p53 keeps a tight lid on unchecked cell growth but doesn't wreak havoc in healthy cells. Scientists now show just how finely tuned the system is and how little it takes to tip the balance.

What happens to p53 after DNA damage?

One view holds that after DNA damage occurs, enzymes directly modify p53 and that those modifications change the structure of p53 in such a way that neither Mdm2 nor Mdmx are able to bind. In an alternative scenario the same enzymes—kinases that attach phosphate groups to proteins—modify the negative regulators, accelerating their degradation and freeing p53 of their antagonists. Of course, it may well be that both views are correct, but the extent to which each contributes to p53 control remains an important unanswered question.

Does P53 stop cancer cells from dividing?

As a powerful tumor suppressor, p53 turns on genes that either halt cell division to allow time for repair of damaged DNA or, when all rescue attempts prove futile, to prevent cells with genetic defects from dividing, as this would fuel the development of cancer. Consequently, before any tumor cell can start proliferating willfully, it needs to escape from p53's iron fist.

Does p53 protect against cancer?

Since p53 also protects against wayward cell proliferation caused by oncogenes such as c-myc, the researchers permanently activated c-myc in the B cell lineage to mimic human endemic Burkitt's lymphomas. They observed that mice with defective Mdmx developed very aggressive lymphomas at a very young age. Thus, control by Mdmx is critical to balance the severity of the response to DNA damaging agents, while also preventing induction of cancer by activated oncogenes.
