Vaccine against HER2-positive breast cancer offers complete protection in lab

Researchers at Wayne State University have tested a breast cancer vaccine they say completely eliminated HER2-positive tumors in mice - even cancers resistant to current anti-HER2 therapy - without any toxicity.

Inherited one-hit gene mutation provides new opportunity for colon cancer prevention

More than 30 years ago, Alfred Knudson Jr., M.D., Ph.D., revolutionized the field of cancer genetics by showing that a person must lose both their paternal and maternal copies of a particular class of cancer-inhibiting genes, called tumor-suppressor genes, in order to develop cancer.

Scientists identify kidney failure susceptibility gene

Scientists at Johns Hopkins schools of Public Health and Medicine have, for the first time, identified variants in the gene MYH9 that are associated with increased risk for non-diabetic end stage renal disease (ESRD,) which is the near-loss of kidney function leading to either dialysis of transplant. MYH9, located on the 22 chromosome, is the first gene identified for common forms of kidney disease.

Significant benefits in non-small-cell lung cancer from customizing erlotinib treatment

Lung cancer patients whose tumors carry specific genetic mutations can achieve significantly longer survival when treated with targeted therapies such as erlotinib, Spanish researchers report.

Scientists discover common variants in the human genome conferring risk of bladder cancer

Scientists at deCODE genetics and colleagues at Radboud University Medical Center in the Netherlands today report the discovery of two common single-letter variants in the human genome (SNPs) that confer increased risk of urinary bladder cancer.

Key component of chronic obstructive pulmonary disease identified

For the first time, researchers have demonstrated a close correlation between the decline in a key component of the lung's antioxidant defense system and the progression of chronic obstructive pulmonary disease (COPD) in humans.

Phase I trial for new tuberculosis vaccine

This week, a new vaccine "VPM1002" has entered the clinical phase I trial in Neuss, Germany, where it is being tested for safety on voluntary subjects. VPM1002 is based on a vaccine that has been in use since 1921, and has been genetically engineered to prevent infection with tuberculosis bacteria much more effectively than its predecessor.

Risk of breast cancer mutations underestimated for Asian women, Stanford study shows

Oncologist Allison Kurian, MD, and her colleagues at the Stanford University School of Medicine were perplexed. Computer models designed to identify women who might have dangerous genetic mutations that increase their risk of breast and ovarian cancer worked well for white women. But they seemed to be less reliable for another ethnic group.

Drug-resistant plague - A bioterrorism concern?

The bacterium responsible for the "Black Plague," which led to the deaths of over 75 million people worldwide in the 14th century, may have other nasty tricks. Yersinia pestis can normally be treated and cured with a course of antibiotics, if caught within a few days of the symptoms.

Genetic mutation prevents fetal malaria transmission, study says

A genetic mutation of the fetal gene sFlt1 might protect fetuses of first-time pregnant women from contracting malaria, according to a study published online Sept. 8 in Proceedings of the National Academy of Sciences, ANI/Thaindian News reports.

The underdevelopment of a specific brain region may cause schizophrenia

The underdevelopment of a specific region in the brain may lead to schizophrenia in individuals. According to research published today in BioMed Central's open access journal Molecular Brain, dentate gyrus, which is located in the hippocampus in the brain and thought to be responsible for working memory and mood regulation, remained immature in an animal model of schizophrenia.
