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).

Animal model of Parkinson's disease reveals striking sensitivity to common environmental toxins

In findings that support a relationship between agricultural chemicals and Parkinson's disease, two groups of researchers have found new evidence that loss of DJ-1, a gene known to be linked to inherited Parkinson's disease, leads to striking sensitivity to the herbicide paraquat and the insecticide rotenone.

British Heart Foundation gene research helped by thousands of brothers and sisters

An unusual British Heart Foundation (BHF) 'DNA database' from brothers and sisters across the UK has enabled researchers to pinpoint six genetic 'hotspots' that can double the risk of developing early heart disease.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Chinese scientists clone a goat

It was released on August 24, 2005 by Prof. Chen Dayuan (Da-Yuan Chen) from the CAS Institute of Zoology that the first success in cloning Asian Yellow Goat by nuclear transfer had recently been achieved in east China's Shandong Province.

DNA research: learning the language of genes

Griffith University's Dr Christine Wells is one of just a handful of women scientists in the global FANTOM consortium which has announced a major breakthrough in unraveling the mammalian genome.

Genetic hot spots double the risk of early heart disease

According to researchers in the UK there are six genetic "hotspots" that can double the risk of developing early heart disease.

Genome of mammals is much more complex than previously thought

More than 100 scientists from Australia, Asia, Europe and the US have been probing the genome of the mouse in a joint study lasting several years.

New recommendations for screening for BRCA1 and BRCA2 gene mutations

The United States Preventive Services Task Force issues new recommendations for screening for BRCA1 and BRCA2 gene mutations in the Sept. 6, 2005, issue of Annals of Internal Medicine.

Researchers discover one of the reasons why melanoma is so ruthless

About 60,000 Americans will be diagnosed with melanoma this year, says the American Cancer Society, and 10,000 of those cases will be fatal. If not caught in the early stages, melanoma can be a particularly virulent form of cancer, spreading through the body with an efficiency that few tumors possess.

New findings suggest balancing Chk1 activity will produce less toxic cancer drugs

A study published by The Burnham Institute in the September edition of Molecular Cell reports that a cell-cycle checkpoint protein, known to be activated by an important class of anticancer drugs, may play crucial roles in both the hampering of therapeutic actions and aiding cancer cells to "recover" and start dividing again after treatment with these drugs.

UK fertility specialist and broadcaster says embryonic stem cell research promises are hyped up

According to a well known fertility specialist and broadcaster in the UK, the promise of embryonic stem cell research has been oversold by scientists.

Rett Syndrome gene discovery

Adrian Bird of the University of Edinburgh and colleagues report in the online issue of Molecular Cell that the "Rett Syndrome protein", MeCP2, only binds to genes with a specific sequence of nucleotide bases. This knowledge will aid in the identification of the genes that are regulated by the gene MECP2

Overall genome landscape between chimps and humans can be attributed to large segmental duplications

A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome.

Potential new way to fight HIV

Researchers have confirmed for the first time the benefit of an innate defense system present in the few patients who remain healthy after years of infection with HIV despite receiving no treatment, according to an article published in the September edition of the Journal of Virology.

Scientists demonstrate power of new generalized screen to find function of noncoding RNAs

A team of investigators at The Scripps Research Institute and the Genomics Institute of the Novartis Research Foundation (GNF) have discovered a way to screen hundreds and potentially thousands of "noncoding" RNA molecules to discover their functions within cells.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."
