Gene therapy shows effect in heart patients

The first double-blind, placebo-controlled randomized trial of VEGF gene injections into the heart muscle of patients with coronary artery disease with the intention of spurring growth of new blood vessels showed significant effects on heart wall motion, although blood flow was not significantly better in treated patients, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

DNA packaging linked with cancer

New laboratory findings at the University of Illinois at Chicago suggest that what lies outside cancer cells is at least as important as the genes inside in explaining a tumor's malignancy.

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.

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.

Genomics and proteomics to increase the efficiency of drug discovery and development

While the United Sates is still the world leader, Europe is having a good deal of success in the field of advanced genomics and proteomics research. Significant government funding together with the presence of large pharmaceutical companies has made Europe a major competitor in the efforts to deploy genomics and proteomics as vital tools in drug discovery and development.

Pair of cancer genes found to drive both cell migration and division

Johns Hopkins researchers have found that two genes already known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell.

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).

Certain combinations of genes increase the risk of developing cervical cancer

Certain combinations of genes that encode receptors on innate immune cells increase the risk of developing cervical cancer, according to a study by Mary Carrington and colleagues in the April 4 issue of The Journal of Experimental Medicine.

Step toward a potential treatment for Huntington's disease

Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntington's disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the disease.

Chronic inflammation caused by too little stomach acid leads to gastric cancer

When it comes to gastric cancer, too little stomach acid can be just as dangerous as too much, according to scientists at the University of Michigan Medical School. Both extremes create inflammatory changes in the stomach lining and a condition called chronic atrophic gastritis, which over time often leads to cancer.

Why smokers lung is resistant to steroid treatment

UK researchers think they are close to finding the first effective treatment to fight one of the biggest killer diseases in the UK. Professor Peter Barnes will present the work at the British Endocrine Societies 2005 meeting in Harrogate.

Mutations in the HFE gene directly associated with chronic joint disease

Mutations in the HFE gene, which is involved in iron regulation, seem to be directly associated with chronic joint disease (or haemophilic arthropathy) among haemophilic patients, claim a team of Portuguese scientists in the April issue of the journal Blood.

New chemicals to inhibit HIV infection

In corporation with peers from the Mount Sinai School of Medicine, New York University, researchers from the University of Science and Technology of China (USTC), a CAS affiliate, have come up with new chemical inhibitors against HIV reproduction, marking a significant progress in the development of anti-AIDS drugs based on natural host resistance.

Autistic children found to have abnormal metabolic profile

Autism, a neurodevelopment disorder which has increased tenfold over the last 15 years, now affects 30 of every 10,000 children in the United States.

Potential therapeutic role for the ataxin-3 protein for Machado-Joseph disease

The repetition of three little "letters" within the gene that codes for the ataxin-3 protein is both the cause of and perhaps a solution to Machado-Joseph disease and an entire family of similar genetic disorders, according to researchers at the University of Pennsylvania.

Scientists identify novel regulator of telomere homeostasis

Each of our 46 chromosomes is capped by a telomere – a long stretch of repeated DNA (TTAGG). Telomeres play a key protective function in our cells, and now Dr. In Kwon Chung and colleagues at Yonsei University (Seoul, Korea) and the University of Central Florida reveal a novel mechanism to modulate telomere length.

Location on chromosome 2 that may contain one or more genes that contribute to dyslexia

Researchers trying to tease out the genetic basis of dyslexia have discovered a location on chromosome 2 that may contain one or more genes that contribute to the reading disorder and make it difficult for people to rapidly pronounce pseudowords.

Exposure to organochlorine compounds increases the risk of suffering colorectal cancer

A team of researchers at the Universitat Autònoma de Barcelona, The Catalan Institute of Oncology and the Higher Council for Scientific Research (CSIC) have published a study indicating that exposure to organochlorine compounds, which we ingest in our diets, increases the risk of suffering colorectal cancer.

New miniature sensors for analysing DNA

The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain.
