New insight into age-related macular degeneration

Age-related macular degeneration is the leading cause of blindness in older adults, yet researchers are still in the dark about many of the factors that cause this incurable disease.

Multiple rare mutations within a single gene may increase risk for autism

While debate still rages over the 'cause' of autism, mounting evidence suggests that genetic factors play a major role in the disease.

Plant toxins in the diets of early humans drove the evolution of taste

Plant toxins in the diets of early humans drove the evolution of a bitter taste receptor better able to detect them, suggests new genetic research by scientists at University College London, Duke University Medical Center, and the German Institute of Human Nutrition.

Study offers a unique perspective on the beginnings of the alcohol experience and usage patterns of 12-year-olds

Clues looking into the root causes of alcoholism are emerging from new findings that center on the genetic patterns of young drinkers, with particular focus on why adolescents are more likely to drink large quantities of alcohol even if they need more alcohol to get the effects they desire.

Researchers have identified 23 new longevity genes

Researchers have identified 23 new longevity genes by screening the genome of Caenorhabditis elegans, a small worm that is used as a model organism in genetics studies. The findings are reported in the inaugural issue of PLoS Genetics.

Potential new target for stomach cancer therapy

It started several years ago with the observation that a large group of seemingly unconnected genes were behaving differently in patients with stomach cancer.

Discovery of a receptor that appears to function as one "lock" that HSV opens to allow it to enter human cells

It's one of the most common viruses in America, and one that causes the most guilt and shame. It can get inside almost any kind of human cell, reproduce in vast numbers, and linger for years in the body, causing everything from recurrent genital blisters to sores around the mouth. Its complications can kill, and it may increase susceptibility to many nerve and brain disorders.

New clues for the understanding of dementia

Researchers at the Medical Research Council MRC Prion Unit and the Department of Neurodegenerative Disease at the Institute of Neurology, University College London - in collaboration with groups from Copenhagen, Aarhus, Lund and Cambridge - have identified a gene that, when mutated, causes an early onset dementia.

Hidden secrets on the nature and timing of genome evolution in mammals revealed

Breakages in chromosomes in mammalian evolution have occurred at preferred rather than random sites as long thought, and many of the sites are involved in human cancers, an international team of 25 scientists has discovered.

Role of IL-24 in regulating the immune system

Researchers at Introgen Therapeutics and their collaborators at The University of Texas M. D. Anderson Cancer Center have published new findings on the role of IL-24 in regulating the immune system in the current online issue of the Journal of Leukocyte Biology.

Crucial molecular link between a hepatitis B virus (HBV) and hepatocellular carcinoma (HCC)

Researchers at The University of Texas M. D. Anderson Cancer Center have uncovered a crucial molecular link between a viral infection and development of a common and fatal form of liver cancer. In the process, they have identified a possible way to treat this disease as well as a number of other cancers.

21 Jul 2005

Biological breakthrough that could offer new hope in the fight against liver cancer

Professor John Mayer and Dr Simon Dawson, in collaboration with colleagues at Japan's Kyoto University, have discovered the function of a new liver oncoprotein - or cancer causing protein - which could be the first step to finding effective new treatments for the deadly illness.

Maintaining a healthy weight in children may be one good way to keep a healthy blood lipid profile and a happy heart

A study of 400 high school age children with a variety of fitness and fatness levels showed that fatter youths had unfavorable lipid profiles, including higher levels of triglycerides and higher ratios of total cholesterol to the protective HDL cholesterol or high density lipoprotein.

Fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta

"What we found is that the beta estrogen receptor plays a role in moving the egg outside the ovary so it can be fertilized," said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. "We never knew before what function this receptor played in reproduction."

University of Florida researcher finds way to explore role of microRNAs in specific tissue

University of Florida researchers have learned how to selectively shut down a flyweight-sized genetic molecule that packs a heavyweight punch, a discovery that may help doctors better understand cancer, birth defects and other health problems.

SIRT1 gene suppresses longevity

Researchers have determined that a gene present in mouse cells limits the number of times that a cell can divide. The gene is involved in a process, called senescence, which is thought to ensure that aging cells do not pass on harmful mutations.

20 Jul 2005

One of the first studies to define how unique we are on the genetic level

We all share the same genetic code, but a team from the Institute of Food Research (IFR) has found that the way our genes function varies significantly between individuals, particularly in some key areas including the immune system.

Variant of a common protein plays a primary role in Type 2 diabetes and obesity

Scientists in France and the United States report that a variant of a common protein plays a primary role in Type 2 diabetes and obesity, key features of the "insulin resistance syndrome" that affects more than 50 million people in this country and a similar number in Europe.

Two regions of the human genome that appear to explain variation in IQ

It may be that IQ tests are not the only way to measure human intelligence. Scientists at The Queensland Institute of Medical Science (QIMR) have identified two regions of the human genome that appear to explain variation in IQ. Their work was published this week in the American Journal of Human Genetics and has drawn world-wide interest.

Important find will help design appropriate screening and therapy for women carrying fetuses impaired in their growth

In her research, Dr. Andree Gruslin encountered many pregnant women who could not carry their fetuses to term because the placenta, and in turn the fetus, were too small. In once case, she followed a woman who had had eight consecutive miscarriages due to this condition. Thanks to this latest discovery, she now understands why.
