Drinkers with the ADH1C gene at greater risk of colorectal cancer

Chronic drinking is a risk factor for colorectal cancer, possibly through the effects of acetaldehyde, which is created by the alcohol dehydrogenase (ADH) enzyme.

Trial looks at new treatment for solid cancer tumors and non-Hodgkin's lymphoma

Researchers at The Cancer Institute of New Jersey (CINJ) have opened a clinical trial, which aims to evaluate a new treatment for solid cancer tumors and non-Hodgkin's lymphoma (NHL) in combination with a chemotherapy agent called cyclophosphamide.

Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer

A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene.

New insights into cellular senescence

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Researchers find that when cells shut down they also spew proteins into their surrounding environment

Cells shut down and stop dividing when their DNA is damaged, in a process known as cellular senescence, so as to prevent damaged DNA from leading to unregulated cell division and therefore cancer.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Does hormone treatment predispose patients to breast cancer?

Breast cancer, the leading cause of death among women in France, is the most commonly occurring cancer in women.

Researchers reveal a new aspect of tumor development

The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses.

Bionovo to present phase 1B trial results of BZL101 in metastatic breast cancer

Bionovo, Inc. has announced the company will present results from the Phase 1B clinical trial of their lead drug candidate for advanced metastatic breast cancer, BZL101, at the Society for Integrative Oncology's Fifth International Conference in Atlanta, Georgia.

Grape seeds could ward off Alzheimer's

Australian scientists are suggesting that grape seeds may be a potential treatment in warding off Alzheimer's disease.

Calcitriol - active form of vitamin D - may protect us from radiation

Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body's main protections against damage from low levels of radiation.

Sunesis Pharmaceuticals presents data of Voreloxin in patients with acute myeloid leukemia and ovarian cancer

Sunesis Pharmaceuticals, Inc. presented data from three clinical trials of the company's lead drug candidate, voreloxin (formerly SNS-595), at the Chemotherapy Foundation Symposium held in New York on November 4-8.

Scientists discover how a well-known protein repairs broken DNA ends

During the life cycle of our cells, a minefield of environmental and biological assaults can lead to double-stranded DNA breaks, the most lethal and dangerous form of DNA damage. Now, in research published online this week in Nature, Rockefeller University scientists reveal that when these breaks occur, a protein called 53BP1 helps repair them by mobilizing their dangly DNA ends - findings that uncover a previously unknown aspect of how double-stranded breaks can get fixed.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

Breast feeding lowers breast cancer risk

Experts say women who breastfeed for a year over the course of their lifetime are less likely to develop breast cancer.

Antidepressants can affect male fertility

Researchers in the United States have linked commonly used antidepressants to a reduction in some men's fertility.

No such thing as a 'safe' suntan

Three review papers from leading researchers in the fields of cell biology, dermatology and epidemiology have looked closely at the effects on skin of UV radiation, including that from indoor tanning beds.

New drug might make tumor cells more sensitive to therapy

Scientists at St. Jude Children's Research Hospital have shown that it might be possible to make tumor cells more sensitive to irradiation and some types of chemotherapy by treating them with a drug that cripples their ability to repair DNA damage caused by these therapies.
