STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

Importance of PSA testing in high-risk men, stressed by National Comprehensive Cancer Network

The National Comprehensive Cancer Network (NCCN) recently updated the NCCN Guidelines for Prostate Cancer Early Detection incorporating the results of the recent ERSPC trial that assessed the benefit of PSA screening. The NCCN Guidelines contend that PSA screening does save lives when performed intelligently in men at high-risk of developing the disease.

Don't smoke, exercise and eat sensibly to reduce risk of chronic disease

Four healthy lifestyle factors - never smoking, maintaining a healthy weight, exercising regularly and following a healthy diet - together appear to be associated with as much as an 80 percent reduction in the risk of developing the most common and deadly chronic diseases, according to a report in the August 10/24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Cases of depression and other mental illnesses nearly doubled between 1996 and 2006

The number of Americans under care for depression and other mental illnesses nearly doubled between 1996 and 2006, and the overall cost of treating them jumped by nearly two-thirds, according to the latest News and Numbers from HHS’ Agency for Healthcare Research and Quality.

Recruitment of new neurons slows when old brain cells kept from dying

Recruitment of new neurons slows when old brain cells kept from dying. Like clockwork, brain regions in many songbird species expand and shrink seasonally in response to hormones.

New class of molecules capable of blocking formation of tau protein fibrils

A new class of molecules capable of blocking the formation of specific protein clumps that are believed to contribute to Alzheimer’s disease pathology has been discovered by researchers at the University of Pennsylvania School of Medicine. By assaying close to 300,000 compounds, they have identified drug-like inhibitors of AD tau protein clumping, as reported in the journal Biochemistry.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Childhood cancer survivors treated with radiation may have an increased risk of diabetes

Childhood cancer survivors treated with total body or abdominal radiation may have an increased risk of diabetes, according to a report in the August 10/24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. This correlation does not appear to be related to patients’ body mass index or physical inactivity.

New molecule blocks lymphangiogenesis

Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.

Widespread general use of fluoroquinolones is creating drug-resistant tuberculosis

Use of a common antibiotic may be undercutting its utility as a first-line defense against drug-resistant tuberculosis (TB). Fluoroquinolones are the most commonly prescribed class of antibiotics in the U.S. and are used to fight a number of different infections such as sinusitis and pneumonia. They are also an effective first line of defense against TB infections that show drug resistance. New research shows, however, that widespread general use of fluoroquinolones may be creating a strain of fluoroquinolone-resistant TB.

French DEET research has little relevance and is irresponsible

“Reports of a French study to examine the effects of DEET on the nervous system of insects has little relevance for the widely-used repellent ingredient’s effects on humans, according to independent scientific experts, including those at the U.S. National Pesticide Information Center,” said Susan Little, director of the DEET Education Program, Washington, D.C.
