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.

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.

Current state of knowledge and experience with vascular birthmarks

The September/October issue of Archives of Facial Plastic Surgery contains several articles on the current state of knowledge and experience with vascular birthmarks, which are caused by blood vessels that do not form correctly.

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.

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.

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.

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.

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.

Compounds found in broccoli, cauliflower, and watercress block lung cancer progression

A family of compounds found in cruciferous vegetables, such as broccoli, cauliflower, and watercress, blocked lung cancer progression in both animal studies and in tests with human lung cancer cells, report researchers from Georgetown University Medical Center and the Institute for Cancer Prevention.

Molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage

Scientists from Maryland and New Jersey have identified a molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage.

Does surgery induce angiogenesis in dormant breast cancer?

Analysis of breast-cancer relapse patterns from two independent databases provides indirect evidence for the theory that surgery to remove the primary tumor may initiate formation of a new blood supply (angiogenesis) in formerly dormant metastases, accounting for a pattern of early relapse in younger women.

New and unusual class of genes plays an important role in the development of chronic lymphocytic leukemia

The study found that the loss of two genes for producing small molecules known as microRNAs enables damaged cells to survive, rather than normally self-destructing before they become cancerous.

Cellular mechanism discovery could lead to new treatments for rheumatoid arthritis, multiple sclerosis and Crohn's disease

A major finding by researchers at the La Jolla Institute for Allergy & Immunology (LIAI) has identified a previously unknown cellular mechanism that acts as an off switch for immune system function.

Combining radiation, chemotherapy and liver transplantation increases survival in bile duct cancer patients

A new treatment for patients with a type of bile duct cancer promises a greater chance at survival by combining radiation, chemotherapy and liver transplantation, Mayo Clinic physicians report in the September issue of the Annals of Surgery.

Discovery of mechanism linking color vision and cancer genes

Biologists at New York University have discovered a system by which a random choice between two distinct cellular fates in the fruit fly eye becomes firmly established.

Depression may hasten the progression of heart disease

In a study of 32 people with heart failure, the 14 patients who felt the most depressed had nearly twice the levels of this protein in their blood.

Letrozole following tamoxifen may benefit women with breast cancer

Switching to the drug letrozole following 5 years of treatment with tamoxifen reduces the risk of hormone-dependent breast cancer recurrence, but not overall survival, among postmenopausal women, according to a new study in the September 7 issue of the Journal of the National Cancer Institute.

3D gradient-echo MRI examinations useful in detecting most lethal of all major cancers

The study included 57 patients who had clinical symptoms of pancreatic cancer. All had contrast enhanced 3D gradient-echo MRI examinations.

Profile of immune cells in axillary lymph nodes predicts disease-free survival in breast cancer

Breast cancer often spreads through the lymph nodes in the arm pits (so-called axillary lymph nodes), and whether these lymph nodes are tumor-free or contain small metastases is an important factor in the decision of how aggressively to treat a patient.
