India Finds New Use for an Old Bug

...re built up in Delhi University for sequencing the chromosome number 11 of rice, as part of the global rice genome project, is used for cracking the genome of Mw, says Hasnain, who is coordinating the project. The sequencing of Mw and a large-scale clinical trial with the Mw vaccine are two parts of a study f...

New Genetic Test Predicts Eye-Cancer Patients' Futures

A Novel Technique That Detects "Cancer Genes" From The Breath Of Smokers

...tial oncogene, are located close to one another on chromosome 21. When fused, TMPRSS2 drives over-expression of the ERG gene. According to Perner, fusion can occur when the piece of DNA separating the genes breaks off and the genes merge (a process described as "fusion through deletion"), or if parts of each ge...

Fighting cancer - Multiple Myeloma with long-term therapy

...re not as successful, and those who did not have a chromosome 13 deletion.This chromosomal abnormality is found in about 15-20 percent of patients with multiple myeloma and is associated with a poorer prognosis. 'Thalidomide shows great promise for keeping multiple myeloma in check after chemotherapy,' said...

Proteins in lungs of patients with cystic fibrosis

... (palate, lung and nasal epithelium clone) gene to chromosome 20. A genetic locus in this region directs the production of a family of at least 10 proteins. Some of the proteins are short, referred to as "SPLUNCs," while others are long, referred to as "LPLUNCs." Researchers have found that these proteins loc...

Understanding Sleeping Sickness

...demiology, were developed in order to identify the chromosome regions and/or DNA mutations involved in the development of the disease. The researchers used association techniques in order to determine the influence of certain mutations on the DNA of genes coding for particular immune system proteins (cytokines)...

Researchers Uncover Critical Player in Cell Communication

... and is caused by a deletion of a small section of chromosome 7 that contains several genes, including the gene that encodes the TFII-I protein. The discovery came after Desiderio and his team used biochemical “bait” to fish for candidate proteins that physically bind to TFII-I. The fishing expedition returne...

Williams Syndrome, the Brain, and Music

... set of about 20 genes is deleted from one copy of chromosome seven, catapulting the carrier of the deletion into a world where people make much more sense than objects do. “Williams syndrome is a perfect example where a genetic predisposition interacts with the environment to sculpt the brain in unique ways...

Gene Transfer Using Mutant Form of Good Cholesterol Cuts Vascular Plaque and Inflammation

...plant from male mice. Because male DNA carries a y chromosome and female DNA does not, the gender mismatch enabled the researchers to precisely track the donor bone marrow. To deliver the gene to the arterial wall, the researchers used a “signal molecule” when they put the genes into the bone marrow. The sign...

Researchers Locate Genetic Link for Nicotine Dependence Among African Americans

...hout the world. Their results revealed a region on chromosome 10 that showed a significant linkage to smoking quantity and other measures of smoking dependence. They also identified three other regions that met the criteria for linkage to at least one ND measure. Some of these regions have been linked to smokin...

Metastasis Of Ocular Melanoma To Liver Can Now Be Calculated

AMD influenced by Variation in 3 Genes

...rom alleles at these three genes, including CFH on chromosome 1, complement factor B (BF) and complement component 2 (C2) genes on chromosome 6, and the LOC gene on chromosome 10. They estimate that genotypes related to five variants in these...

Toxic Strand Of RNA Causes Myotonic Muscular dystrophy

...h myotonic muscular dystrophy has that mutation on chromosome 19, which is now part of a genetic, diagnostic test for myotonic dystrophy. In their latest research, Mahadevan and colleagues created a new type of mouse model with many extra copies of the CTG repeats, each attached to DNA for a protein that glow...

Gene variants hold clues about vulnerability to cardiovascular disease

... such a region: a small section of the long arm of chromosome 3 where GATA2 is located. Chromosome 3 is one of the 23 pairs of chromosomes that comprise the human genome. In a separate study led by David Seo, M.D., assistant professor of medicine, another group of Duke researchers found that GATA2 was turned...

Human Embryonic Stem Cells Could Be Later Used In Therapeutic Cloning

...enetic events leading to the inactivation of one X chromosome in female cells. Failure to establish a normal pattern of DNA methylation during embryogenesis can cause immunological deficiencies, mental retardation and other abnormalities such as Rett, Prader-Willi, Angelman and Beckwith-Wiedemann syndromes.

Obsessive-Compulsive Disorder Is Familial

...t found signs of OCD-related genetic variations on chromosome 9, in the area of SLC1A1. Since that time, they have been zeroing in on the gene and its nearby stretches of DNA, using analyses of single nucleotide polymorphisms that look at specific differences between individuals within the gene. At the same t...
