People with Ala12 gene variant need to watch out for high fat in their diets

New evidence in mice bolsters the notion that a version of a gene earlier shown to protect lean people against weight gain and insulin resistance can have the opposite effect in those who eat a high-fat diet and are heavier, reveals a report in the January 7th issue of the journal Cell Metabolism, a Cell Press publication.

Discovery of new way for bacteria to transfer toxic genes to unrelated bacterial species

In a laboratory experiment, the scientists from NYU School of Medicine discovered that Staphylococcus aureus, a notorious bacterium that causes toxic shock syndrome and many other types of infections and is the scourge of hospitals nationwide due to its growing antibiotic resistance, could co-opt viral parasites as secret pipelines for transferring toxin genes to vastly different bacterial species.

Discovery of 'on switch' for cell death signaling mechanism

Scientists at Burnham Institute for Medical Research (Burnham) have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex (DISC), which is responsible for triggering apoptosis (programmed cell death).

Why prostate cancer patients fail hormone deprivation therapy

The hormone deprivation therapy that prostate cancer patients often take gives them only a temporary fix, with tumors usually regaining their hold within a couple of years.

Matrix fragments trigger fatal excitement

Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org).

Long-term gene therapy used to reverse heart damage in heart failure

Long-term gene therapy resulted in improved cardiac function and reversed deterioration of the heart in rats with heart failure, according to a recent study conducted by researchers at Thomas Jefferson University's Center for Translational Medicine.

FDA approves injectable drug degarelix for advanced prostate cancer

The U.S. Food and Drug Administration recently approved the injectable drug degarelix, the first new drug in several years for prostate cancer.

Targeted nanoparticles deliver therapeutic DNA to cancer cells

Given that cancer is a disease caused by gene mutations, cancer researchers have been striving to develop gene therapies aimed at correcting these mutations. However, these efforts have been hobbled by the difficulty in safely and efficiently delivering anticancer genes to tumors. Nanoparticles, however, may solve these delivery issues, and two recently published studies, using two different types of nanoparticles, lend credence to that hypothesis.

Researchers look at processes asbestos fibers use to trigger cancer in human cells

Ohio State University scientists believe they are the first in the world to study the molecular underpinnings of cancer by probing individual bonds between an asbestos fiber and human cells.

Receptor for prostaglandin-E2 plays key role in atherosclerosis development

Atherosclerosis - a disease that includes the buildup of fatty, cholesterol-laden lumps of cells inside the artery wall - is the underlying cause of heart attacks and strokes.

Fruits, vegetables and fiber may cut risk of breast cancer recurrence in women without hot flashes

A secondary analysis of a large, multicenter clinical trial has shown that a diet loaded with fruits, vegetables and fiber and somewhat lower in fat compared to standard federal dietary recommendations cuts the risk of recurrence in a subgroup of early-stage breast cancer survivors - women who didn't have hot flashes - by approximately 31 percent.

Researchers solve failed vaccine mystery

Research led by Johns Hopkins Children's Center scientists has figured out why a respiratory syncytial virus vaccine used in 1966 to inoculate children against the infection instead caused severe respiratory disease and effectively stopped efforts to make a better one.

GUMC researchers find gene inactivated in two aggressive cancers

Researchers at Georgetown University Medical Center have found a gene they say is inactivated in two aggressive cancers - malignant melanoma, a form of skin cancer, and glioblastoma multiforme, a lethal brain tumor.
