Study says protein p53 weeds out mutations

San Diego scientists have identified a protein in embryonic stem cells that helps weed out mutations as the cells proliferate. Its action may protect a developing embryo from DNA damage that could lead to cancer later in life.

The number of mutated genes driving cancer development is greater than previously thought, research shows.

Researchers have discovered a  genetic mutation that causes an aggressive form of childhood  leukemia and said on Thursday it may mean that drugs being  developed for Alzheimer's disease could also provide a better  treatment for the cancer.

A painstaking scan of the DNA of tumor cells shows hundreds of previously unsuspected genes are involved in cancer, researchers said on Wednesday in a finding that offers new ways to fight the disease.

A genetic test that grades breast- cancer aggressiveness also identifies low-risk women who don&#39;t need chemotherapy, potentially sparing 50,000 each year from a toxic treatment that doesn&#39;t help them, researchers said.

In the battle against cancer, saving two patients out of 17 may seem modest enough. But researchers see hope that using genetically altered immune cells to attack tumors -- as was done in this study -- may hold the key to eventually defeating various cancers.

MONDAY, Nov. 15 (HealthDayNews) -- Data on nearly a million families suggest that mutations in BRCA1 and BRCA2 genes -- which are strongly linked to some breast cancers -- may also confer a slight increase in risk for pancreatic, prostate and stomach cancers.

Researchers say they have eliminated leukemia cells in mice by shutting off a molecule necessary for the cancer cells&#39; survival.

Researchers say they have found a way to reverse resistance to one of the most effective anti-cancer drugs.

Scientists say they have found two genetic mutations that could triple the risk of developing bowel cancer.

Proteins found on the outside of cancer cells could be targeted by a drug &quot;guidance system&quot; which seeks out and destroys the disease, scientists have said.

By restoring tiny bits of genetic material missing from breast tumors in mice, U.S. researchers said on Wednesday they were able to block the cancer's ability to spread.

Professionally led support groups may ease anxiety and depression in women who carry gene mutations linked to breast and ovarian cancers, a new study suggests.

WEDNESDAY, Sept. 1 (HealthDayNews) -- A protein called Stat3 sets skin cancer development in motion, says a study by researchers at the University of Texas M.D. Anderson Cancer Center.

Loss of a tumor suppresser gene called Rb may be the first step in the development of prostate cancer, according to findings from experiments in mice.
