Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 6, one copy inherited from each parent, form one of the pairs. Chromosome 6 spans about 171 million base pairs (the building blocks of DNA) and represents between 5.5 percent and 6 percent of the total DNA in cells.
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 6 likely contains between 1,100 and 1,600 genes.
Genes on chromosome 6 are among the estimated 20,000 to 25,000 total genes in the human genome.
Dasatanib, a medication currently approved as treatment for drug-resistant chronic myeloid leukemia, provided patients with quicker, better responses as a first therapy than the existing front-line drug, according to researchers at The University of Texas MD Anderson Cancer Center.
Scientists have identified a region of DNA that appears to be involved in the development of pre-cancerous bowel growths (polyps) and that may contain a gene involved in the progression of bowel cancer.
Ablexis, LLC, a biotechnology company dedicated to developing an innovative, next-generation platform for antibody drug discovery, announced today that it has completed a $12 million Series A financing. The round was led by Third Rock Ventures and included Pfizer Venture Investments. Proceeds from the financing will be used to continue advancing Ablexis' proprietary AlivaMab Mouse transgenic mouse platform for the discovery of human therapeutic antibodies.
Many tumor cells would not be viable due to aberrant chromosome distribution if they had not developed a special trick. Scientists from the German Cancer Research Center have investigated which genes are responsible for this survival strategy of cancer cells.
Scientists from Singapore, China and USA have identified three new susceptibility genes in a genome-wide association study of nasopharyngeal carcinoma (NPC). The study, led by the Genome Institute of Singapore (GIS), a biomedical research institute of the Agency for Science, Technology and Research (A*STAR), and the Sun Yat-Sen University Cancer Centre, identified genetic risk factors of NPC that advance the understanding of the important role played by host genetic variation in influencing the susceptibility to this cancer.
Writing the latest pages of an anthropological mystery, scientists propose in this month's Archives of Neurology that it is highly possible that Auguste Deter, the first identified Alzheimer disease patient, carried the N141I presenilin-2 mutation—the same one as in present-day U.S. families descended from German emigrants who settled near the river Volga in Russia.
Although congenital heart disease represents the most common major birth defect, scientists have not previously identified the common variation in the genes that give rise to it. Now genetics and cardiology researchers, two of them brothers, have discovered a genetic variant on chromosome 5 that strongly raises the risk of congenital heart disease.
Scientists have discovered a gene that could lead to more effective treatments for a form of childhood brain cancer called paediatric high grade glioma.
The most comprehensive analysis yet of the genetic imbalances at the heart of childhood brain tumors known as high-grade gliomas (HGGs) identified a cancer gene that is unusually active in some tumors and is now the focus of a St. Jude Children's Research Hospital clinical trial.
Pfizer Oncology will present new data highlighting the company's focused approach to cancer drug development through the identification and validation of molecular targets. These results will be presented at the 46th Annual American Society of Clinical Oncology meeting in Chicago from June 4-8.
Researchers at the J. Craig Venter Institute (JCVI), a not-for-profit genomic research organization, published results today describing the successful construction of the first self-replicating, synthetic bacterial cell. The team synthesized the 1.08 million base pair chromosome of a modified Mycoplasma mycoides genome.
Researchers have identified an important cancer gene that could lead to more effective drugs being developed to fight paediatric high grade glioma, a disease which currently has a poor prognosis.
New research discovers a combination of drugs that may prove to be a more effective treatment for a lethal form of leukemia. The study, published by Cell Press in the May issue of the journal Cancer Cell, reports that the new therapeutic strategy effectively targets notoriously intractable leukemia stem cells that often escape standard treatment and are a main factor in disease relapse.
Tufts University's School of Arts and Sciences has received a $9.5 million grant to create research space that will house a Collaborative Cluster in Genome Structure and Developmental Patterning in Health and Disease.
The ability of yeast cells to convert sugar to alcohol, the key process in the production of beer and wine, can be attributed to a remarkable evolutionary process. The genes that allow yeast to digest sugars in fruits and grains have been duplicated several times over the course of time - allowing for optimal conversion of different types of sugars (such as sucrose and maltose) into alcohol.
Chromosome 22q11 deletion syndrome (also known as DiGeorge syndrome) is the most common human chromosome deletion syndrome, having an estimated incidence of at least one in 4,000 live births.
Oxygen levels in the lab can permanently alter human embryonic stem (ES) cells, specifically inducing X chromosome inactivation in female cells, according to Whitehead Institute researchers. Human ES cells have been routinely created and maintained at atmospheric levels of oxygen, which is about 20%. Cells in the body are usually exposed to only 1-9% oxygen.
Hana Biosciences Inc.,, a biopharmaceutical company focused on strengthening the foundation of cancer care, today reported financial results for the first quarter ended March 31, 2010, and provided a corporate update.
Whitehead Institute researchers have determined a key part of how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division.
An international consortium of genetics experts has issued a consensus statement recommending chromosomal microarray (CMA) as the new standard practice for genetic evaluation of children with unexplained developmental delay, autism or birth defects.
