DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Mesenchymal multipotency of adult human periosteal cells demonstrated by single-cell lineage analysis

Inflammation, cartilage and bone erosions, joint destruction--that's the typical progression of arthritis and most rheumatic diseases.

Study demonstrates the importance of familial factors in the general development of cancer

Studying thousands of people, researchers at The University of Texas M. D. Anderson Cancer Center have documented a 25 percent increased risk of developing one of a number of cancers in first-degree relatives of lung cancer patients who have never smoked compared to families of people who neither smoke nor have lung cancer.

Weill Cornell experts publish review of genetic medicine

In an article published in the April issue of Nature Reviews Genetics, two experts at the Weill Medical College of Cornell University sum up the achievements, challenges and promise of a burgeoning field: genetic medicine.

Omega-3 fatty acids inhibit the growth of liver cancer cells

Two new studies by a University of Pittsburgh research team suggest that omega-3 fatty acids - substances that are found in high concentrations in fish oils and certain seeds and nuts - significantly inhibit the growth of liver cancer cells.

Scientists use bacteria found naturally in soil to produce new antibiotics in the fight against drug-resistant "Super-bugs"

Antibiotic resistance is a major problem worldwide and there is an urgent need for new antibiotics to be developed. Potential new drugs are usually made in the lab which is complicated and time-consuming.

Custom made nanoparticles will transform cancer diagnosis and treatment

Researchers have developed "custom" nanoparticles that promise to provide a more targeted and effective way of delivering anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles.

Mouse Brain Gene Expression Map at St. Jude - powerful new tool for studying brain development

Scientists at St. Jude Children's Research Hospital have given investigators around the world free access to a powerful tool for studying brain development.

Study on fruit flies offers new approach to understand human response to viral infections

A research team led by UC Riverside scientists has shown that the common fruit fly can serve as an excellent model for studying the immunity animals are born with for fighting viral infections.

Researchers develop new tool to find gene control regions

Researchers at the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function.

RNAi-based inhibitors for created for nearly every human and mouse gene - available to all genetic researchers

An international public-private research team led by scientists at the Broad Institute of MIT and Harvard announced today the construction and availability of an extensive library of molecular reagents to silence most human and mouse genes.

Tobacco plants being used to produce human albumin

Human serum albumin (HSA) is the intravenous protein most commonly used in the world for therapeutic ends. It is employed to stabilise blood volume and to avoid risk of a heart attack, its administration in operating theatres being almost a daily occurrence.

Light activated anticancer drug targeted to DNA using cisplatin like sub-units: Coupling light absorbers to reactive metal centers

One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair. However, it also kills healthy tissue. Many scientists are creating alternative drugs or cisplatin analogs in attempts to find treatments without side effects.

Zinc's role in Alzheimer's disease

Zinc may be a familiar dietary supplement to millions of health-conscious people, but it remains a mystery metal to scientists who study zinc's role in Alzheimer's disease, stroke and other health problems.

Remaining 80% of breast cancer genes may soon be discovered

We are closer to finding the missing 80% of breast cancer genes than ever before thanks to the success of the COSMIC database (Catalogue Of Somatic Mutations In Cancer) the 5th European Breast Cancer Conference (EBCC-5) was told today.

Increase in Vitamin E tied to fewer in utero deaths

Manipulating the in utero environment may alter the onset of cancers that appear later in the lives of mammals, according to a new University of Toronto study published in the journal Carcinogenesis.

23 Mar 2006

Scientists create new molecule that holds promise in fighting disease via gene therapy

Inherited diseases, as well as many cancers and cardiovascular diseases, may eventually be helped by this approach, which delivers therapeutic genes directly to cells. These genes can correct genetic defects, for example, or help the body's immune system fight cancer cells.
