Sun exposure may have an anti-melanoma effect

Italian researchers have found a link between vitamin D and the risk of developing a melanoma and they say that individuals with certain variants in a vitamin D-related gene, called BsmI, may be at an increased risk of developing melanoma.

Early antiretroviral treatment for people with HIV/TB coinfection could reduce mortality by half

People with HIV/tuberculosis coinfection who began antiretroviral treatment within six months of starting TB treatment had a 55% lower mortality rate than people with HIV/TB coinfection who did not begin antiretroviral therapy until after they had finished a six-month TB treatment course, according to a study conducted by researchers at the University of KwaZulu-Natal, Business Day reports (Kahn, Business Day, 9/18).

Researchers turn plant cells into medical factories

VTT Technical Research Centre of Finland will coordinate the large EU research project called SmartCell. The four-year project focuses on developing methods for production of valuable pharmaceutical compounds using plant cells as a production host in an effective and controlled manner.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

Squirrels may know a cure for cancer!

Scientists in the United States believe they have discovered a previously unknown anti-cancer mechanism in some rodents.

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.

Discovery of promising new chemotherapy target for a deadly form of leukemia

Cancer researchers at the Stanford University School of Medicine have discovered a promising new chemotherapy target for a deadly form of leukemia. Their discovery hinges on a novel "double agent" role for a molecular signal that regulates cell growth.

Muscle stem cell identity confirmed

A single cell can repopulate damaged skeletal muscle in mice, say scientists at the Stanford University School of Medicine, who devised a way to track the cell's fate in living animals. The research is the first to confirm that so-called satellite cells encircling muscle fibers harbor an elusive muscle stem cell.

Flies reveal immune cell response to tumour and tissue damage

Research with fruit flies has revealed more in common between simple cuts and scratches and the growth of tumours than might have been expected.

Prostate cancer genes behave like those in embryo

Gene activity in prostate cancer is reminiscent of that in the developing fetal prostate, providing further evidence that all cancers are not equal, Johns Hopkins researchers report. The finding could help scientists investigate how to manipulate the genetic program to fight a disease whose biology remains poorly understood despite more than half a century of investigation.

Geron issued U.S. patent for cardiomyocytes from human embryonic stem cells

Geron Corporation has announced the issuance of U.S. Patent No. 7,425,448, with broad claims to cardiomyocytes derived from human embryonic stem cells (hESCs). The patent runs until at least April 2025 (subject to any patent term extension that may be available). Geron's GRNCM1 program is developing hESC-derived cardiomyocytes for the treatment of heart disease.

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.

New results help predict treatment response in colorectal cancer

Genetic testing can identify a group of patients with advanced colorectal cancer who are likely to survive on average twice as long if treated with the drug cetuximab, late breaking results show.

Benefits of combined treatments against cancer

In cancer therapy, the best results are often achieved by combining treatments such as chemotherapy, radiotherapy and surgery. This multidisciplinary approach is the focus of special symposia at the meetings of the European Society for Medical Oncology (ESMO) and the European Society for Therapeutic Radiology (ESTRO) taking place in Sweden this month.

Carbon nanotube coating improves electrical stimulation therapy used for Parkinson's, depression, chronic pain

Researchers at UT Southwestern Medical Center have designed a way to improve electrical stimulation of nerves by outfitting electrodes with the latest in chemically engineered fashion: a coating of basic black, formed from carbon nanotubes.

Breast cancer vaccine could protect against aggressive HER2-positive breast tumours

Women with a certain type of breast cancer have been given hope in the form of a vaccine which promises to eliminate the cancer tumours.

Study identifies immune response that enables TB bacteria to multiply, provides new target for TB drugs

Researchers have identified an immune system response to tuberculosis that enables TB bacteria to spread through the lungs, providing a new target for TB drug development, according to a study published Sunday in Nature Immunology, AFP/Washington Times reports.
