New centre launched to investigate link between human sugars and disease

A multidisciplinary centre launched today will promote a far broader understanding of the role sugars play in human disease, scientists say.

Molecular models advance the fight against malaria

Research from Dartmouth Medical School, demonstrating how malaria parasites form mutations that make them stubbornly resistant to drug therapy, may hold the key to a new treatments for a disease that afflicts more than half a billion people worldwide.

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

Using X-ray crystallography, researchers have "seen" the structural basis for antibiotic resistanc

Using X-ray crystallography, researchers at Yale have "seen" the structural basis for antibiotic resistance to common pathogenic bacteria, facilitating design of a new class of antibiotic drugs, according to an article in Cell.

Propensity for obesity, diabetes may occur in utero

The adage "You are what you eat" should be rephrased to include "and so are your children," based on metabolic research pioneered by researchers at the University at Buffalo.

Enzyme that helps trigger the development of leukemia

Scientists at the University of North Carolina at Chapel Hill have identified an enzyme that helps trigger the development of leukemia, a cancer of blood cells.

First time video capture of chemical signals that traverse human cells messaging

Researchers at UCSD and UC Irvine have captured on video for the first time chemical signals that traverse human cells in response to tiny mechanical jabs, like waves spreading from pebbles tossed into a pond. The scientists released the videos and technical details that explain how the visualization effect was created as part of a paper published in the April 21 issue of Nature.

Have a laugh a day, it will do you good !

It used to be an apple a day which kept the doctor away now scientists at University College London have found that being happy might be equally beneficial.

Short segments of sugar chains useful in search for new drugs for Alzheimer's

Heparansulfate, which is needed for normal fetal development among other things, is also important for the build-up of amyloid, morbid protein deposits that appear in several serious diseases. This is shown by Uppsala scientists in an article published in the Proceedings of the National Academy of Science.

Scientists reveal the shape of a protein that helps retroviruses break into cells

Retroviruses are among the trickier and more malicious disease agents, causing AIDS and cancers such as leukemia. The viruses manage to sneak into cells with the help of special protein assemblies scattered all over their surfaces. These retrovirus surface proteins cause the membrane envelope of the virus to fuse with the membrane of the cell, spilling virus RNA into the cell to wreak damage.

Scientists use transcription factors to increase insulin production in diabetic mice

A group of Japanese scientists has used gene therapy to deliver three insulin transcription factors, MafA, PDX-1, and NeuroD, to the livers of diabetic mice. As a result, the mice experienced an increase in insulin gene expression and insulin production, raising the possibility that this could eventually be used to treat diabetes.

Bugs in the gut could help doctors develop individualised healthcare

The success of personalised healthcare hinges on a better understanding of how microbes in the gut interact with different medicines report scientists from Imperial College London and Astra Zeneca.

Protein that regulates cholesterol levels may lead to new drug targets in the fight against obesity

A protein that regulates cholesterol levels in the body also is responsible for maintaining a healthy balance between fat storage and fat burning, according to a UT Southwestern Medical Center study that may lead to new drug targets in the fight against obesity.

Findings will stir new research in bacterial evolution

Bacteria acquired up to 90 percent of their genetic material from distantly related bacteria species, according to new research from The University of Arizona in Tucson.

Genetic testing could bolster radiotherapy's effectiveness against cancer

Obtaining a genetic picture of how a tumor will react to the many treatment techniques available could help doctors prescribe therapies customized for individual cancer patients' needs, suggests a Purdue University research team.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Method of gene therapy accurately corrects mutations in disease-causing genes

Harnessing the strength of a natural process that repairs damage to the human genome, a researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes.

Alteration of steroid receptor genes creates fat burning muscle

The Salk Institute scientist who earlier discovered that enhancing the function of a single protein produced a mouse with an innate resistance to weight gain and the ability to run a mile without stopping has found new evidence that this protein and a related protein play central roles in the body's complex journey to obesity and offer a new and specific metabolic approach to the treatment of obesity related disease such as Syndrome X (insulin resistance, hyperlipidemia and atherosclerosis).
