DNA News and Research

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).

Genomes of two E. coli bacteria strains sequenced and analyzed

An international team of researchers from the United States, Korea, and France has sequenced and analyzed the genomes of two important laboratory strains of E. coli bacteria, one used to study evolution and the other to produce proteins for basic research or practical applications. The findings will help guide future research and will also open a window to a deeper understanding of classical research that is the foundation of our understanding of basic molecular biology and genetics.

First high-throughput analysis of Salmonella Typhi gene

For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armouries.

UNC scientists receive GO grant to study the human genome blueprint

Ever since the first genome sequence was published in 2001, scientists have been working to figure out what the sequence means. An analogy is walking across a desert and finding a large book in a language you don't know, then trying to figure out what the book is saying.

Discovery may yield better understanding of protective gut-dwelling bacteria

Medical researchers have long suspected that obscure bacteria living within the intestinal tract may help keep the human immune system in balance. An international collaboration co-led by scientists at NYU Langone Medical Center has now identified a bizarre-looking microbial species that can single-handedly spur the production of specialized immune cells in mice.

Immune-related proteins are potential drug targets for gastric inflammation and cancer

A research team from South Korea studied the complex reaction of gastric inflammation induced by Helicobacter pylori (H pylori) in a systematic manner using a protein interaction network. Their study will be published on September 28, 2009 in the World Journal of Gastroenterology.

New chromosomal abnormality in acute lymphoblastic leukemia

Researchers identified a new chromosomal abnormality in acute lymphoblastic leukemia (ALL) that appears to work in concert with another mutation to give rise to cancer. This latest anomaly is particularly common in children with Down syndrome.

DKC establishes link between genetic mutation affecting telomerase function and human disease

The human genetic disease dyskeratosis congenita (DKC) is an autosomal dominant disease that leads to abnormalities in tissues with a rapid cell turnover - the skin, nails, bone marrow, lungs and gut. Patients with DKC experience life-threatening symptoms. Bone marrow failure increases their risk of fatal infections and cancer. Many die before the age of 30 and management of the disease is limited to trying to treat its symptoms.
