Gene mutation may increase the risk of prostate cancer up to three times in African-American

Researchers have identified a gene mutation that may increase the risk of prostate cancer up to three times in African-American men with a family history of the disease.

Dual association of beta-carotene with risk of tobacco-related cancers

A new study of French women has found that high beta-carotene intake--through a combination of diet or supplementation--is associated with a higher risk of tobacco-related cancers in smokers, but the risk of these cancers decreases with increasing beta-carotene intake in nonsmokers.

Change in gene may be underlying molecular defect in some colorectal cancers

Inactivation of a DNA repair gene may be an early step in the development of sporadic colorectal tumors, and detection of the molecular basis for this inactivation may ultimately be useful in risk assessment for colorectal cancer, according to a new study in the September 21 issue of the Journal of the National Cancer Institute.

Significant death risk linked to airborne particles

Experts may be significantly underestimating air pollution's role in causing early death, according to a team of American and Canadian researchers, who studied two decades' worth of data on residents of the Los Angeles metro area.

Suppression of FOXO1a gene might kill resistant alveolar rhabdomyosarcoma (ARMS) tumors

FOXO1a caused death of tumor cells in laboratory study by triggering expression of caspase-3, which blocks cell division and causes cells to undergo apoptosis, according to St. Jude.

O-GlcNAc sugar is a critical regulator of cells' natural life cycle

The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. The findings are described in the Sept. 23 issue of the Journal of Biological Chemistry, available online now.

Link between tissue tension and tumor formation

Most investigations into cancer have focused on chemical signals, but a new research study provides rare insight into how mechanical force can regulate cellular behavior.

Gaps in the intestinal barrier could be a cause of inflammatory diseases of the gut such as Crohn's Disease

Their research, led by Professor Alastair Watson in the University's Faculty of Medicine, could have important implications for the treatment of patients with diseases like Crohn's - an inflammatory bowel disorder that causes severe ulceration in the intestine, leading to pain, bleeding and diarrhoea.

PUMA protein offers critical insights for developing new anti-cancer drugs

The discovery of how the activities of the protein p53 initiate signals that trigger cell suicide offers critical insights for developing new anti-cancer drugs, according to investigators from St. Jude Children's Research Hospital.

Liverpool scientists have found a way of identifying families at high risk of pancreatic cancer

The team has developed a novel means of testing for pancreatic cancer that will enable doctors to treat the killer disease at its earliest stages. They are also now able to show how the risk of cancer for these patients changes with age.

Survey of general surgeons suggests that the amount of education and training they receive in palliative care is limited

Previous studies have indicated that surgeons receive little training in palliative surgical intervention, the objective of which is to relieve symptoms and improve quality of life rather than cure disease or extend survival, according to background information in the article.

Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence

Using a recently developed mouse model of breast cancer, a team from the University of Pennsylvania School of Medicine has shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

High-fat fare increases risk of heart disease for hospital staff and visitors

Nutrition scientists with the Physicians Committee for Responsible Medicine (PCRM) have conducted a nationwide survey to determine if hospital cafeterias and restaurants are meeting the need for low-fat, cholesterol-free foods that can help people maintain a healthy weight and prevent heart disease, diabetes, and some cancers.

PSA remains the best measure of the likelihood of prostate cancer recurrence after surgery

Despite recent claims by some urologists that measuring the blood protein prostate-specific antigen (PSA) may not be effective in predicting risk of prostate cancer, a Johns Hopkins study of more than 2,000 men confirms that PSA remains the best measure of the likelihood of cancer recurrence after surgery.

Approximately 25 percent of how a person ages is inherited from parents

According to professor Thomas Kirkwood of the University of Newcastle, there is no single gene for ageing. Throughout time, Humans have used energy to get food, produce offspring and survive danger - not to repair and maintain cells. So the maintenance system in the body slowly breaks down.

Possible new target for treating obesity and diabetes

The new target, a molecule called hVps34, is activated by amino acids (nutrients) entering the cell. This molecule triggers the activation of an enzyme, S6 Kinase 1 (S6K1), whose function UC researchers linked last year to obesity and insulin resistance.

Injury prevention could save Maryland at least $700 million per year

In 2003, the total estimated cost of injuries in Maryland due to lost productivity and premature mortality was $1.9 billion dollars.

Carbon nanotubes as transport agents for antimycotics (antifungal agents)

Putting pharmaceutical agents into the body isn't hard, but getting them into targeted areas can be problematic. If drugs aren't taken up by a large enough proportion of cells, a suitable "transport agent" must be used.

Study points to importance of MYC gene in cancer progression

The cancer gene MYC is among the most commonly overexpressed oncogenes in human cancers. Most human cancers demonstrate high levels of MYC or its biological partners, including those of the breast, ovaries, lung, prostate, and skin, as well as leukemias and lymphomas.
