New role uncovered for 'oldest' tumor suppressor gene
Scientists have revealed a brand new function for one of the first cancer genes ever discovered -- the retinoblastoma gene -- in a finding that could open up exciting new approaches to treatment. The retinoblastoma gene is defective in many cancers and is known to play a central role in stopping healthy cells from dividing uncontrollably. This study has found that the gene also has another important function, in helping to 'glue' severed strands of DNA back together.

The CNIO develops an anti-obesity treatment in animal models
The study has been conducted on obese mice and monkeys, using a drug which inhibits the activity of the PI3K enzyme. The body weight loss was exclusively due to a reduction in fat mass and no toxic effects have been noted. The study also found an improvement in the symptoms of diabetes and hepatic steatosis (fatty liver disease). Obesity is one of the top risk factors within the spectrum of serious diseases that constitute metabolic syndrome.

Promising drug target identified in medulloblastoma
Scientists at Dana-Farber/Boston Children's Cancer and Blood Disorders Center have identified a protein critical to both the normal development of the brain and, in many cases, the development of medulloblastoma, a fast-growing brain tumor that usually strikes children under 10. As reported in Developmental Cell, when the researchers cut the level of the protein Eya1 in half in mice prone to develop medulloblastoma, the animals' risk of dying from the disease dropped dramatically.

Fitness level associated with lower risk of some cancers, death in men
Men with a high fitness level in midlife appear to be at lower risk for lung and colorectal cancer, but not prostate cancer, and that higher fitness level also may put them at lower risk of death if they are diagnosed with cancer when they're older, according to a study published online by JAMA Oncology.

Researchers solve science behind scalp cooling and the reasons for hair loss in cancer treatment
HAIR loss is one of the most distressing side-effects of cancer treatment and can even deter some patients from undergoing life-saving chemotherapy. But researchers at the University of Huddersfield are establishing the scientific basis for a rapidly-advancing scalp cooling technology that can ensure hair retention in a vast number of cases.

Could a tampon one day help predict endometrial cancer? Mayo Clinic researchers say yes
Researchers at Mayo Clinic have shown that it is possible to detect endometrial cancer using tumor DNA picked up by ordinary tampons. The new approach specifically examines DNA samples from vaginal secretions for the presence of chemical 'off' switches -- known as methylation -- that can disable genes that normally keep cancer in check.

Why some HPV infections go away and others become cancer
A Duke study finds that the body's ability to clear an infection by the cancer-causing human papilloma virus (HPV) may be largely due to unpredictable division patterns in HPV-infected stem cells, rather than the strength of the person's immune response as previously thought.

New insights into survival outcomes of Asian-Americans diagnosed with cancer
Numerous studies have documented racial differences in deaths from cancer among non-Hispanic whites and African-Americans, but little has been known about survival outcomes for Asian-Americans who have been diagnosed with cancer, until now. A new study from Brigham and Women's Hospital examined cancer patients in eight different Asian-American subgroups and found their cancer-specific mortality was substantially lower than that of non-Hispanic white patients.
