Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 8, one copy inherited from each parent, form one of the pairs. Chromosome 8 spans about 146 million DNA building blocks (base pairs) and represents between 4.5 percent and 5 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 8 likely contains between 700 and 1,100 genes.
Genes on chromosome 8 are among the estimated 20,000 to 25,000 total genes in the human genome.
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.
Researchers studying the common genetic disorder chromosome 22q.11 deletion syndrome have identified key proteins that act together to regulate early embryonic development. One protein is essential to life; in animal studies, embryos without the protein do not survive past the first few days of gestation.
Although genome-wide analysis identified two genetic variations associated with Alzheimer disease, these variations did not improve the ability to predict the risk of AD, according to a study in the May 12 issue of JAMA.
By analyzing the genomes of patients with schizophrenia, genetics researchers have discovered numerous copy number variations—deletions or duplications of DNA sequences—that increase the risk of developing schizophrenia. Significantly, many of these variations occur in genes that affect signaling among brain cells.
Researchers at UT Southwestern Medical Center have discovered how the genetic mutation that causes Fragile X syndrome, the most common form of inherited mental retardation, interferes with the "pruning" of nerve connections in the brain. Their findings appear in the April 29 issue of Neuron.
Scientists at the University of Kentucky Markey Cancer Center have identified a key molecular mechanism in breast cancer that enables tumor cells to spread to adjacent or distant parts of the body in a process called metastasis.
An international consortium of scientists, led by researchers at Johns Hopkins University has identified two genes that when altered are closely associated with cleft lip and/or cleft palate. Cleft lip and cleft palate are among the world's most common congenital malformations and occur in one in every 700 births. The finding is the result of the largest family-based, genome-wide study of cleft lip and/or cleft palate conducted to date. The results were published online by the journal Nature Genetics.
The density of transposable (jumping) elements between sex chromosomes in primates may have important consequences for the studies of human genetic diseases, say Penn State University researchers.
China Medical Technologies, Inc., a leading China-based advanced in-vitro diagnostic company, today announced that it received approval for its AUTOMAGLIA 90 fully-automated ECLIA analyzer as well as Down Syndrome screening kit from the State Food and Drug Administration of China.
Hana Biosciences, a biopharmaceutical company focused on strengthening the foundation of cancer care, today announced that the Company has completed a pre-New Drug Application (NDA) meeting with the U.S. Food and Drug Administration (FDA) related to its lead product candidate, Marqibo for the treatment of relapsed/refractory adult Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL).
Scientists may be one step closer to being able to generate any type of cells and tissues from a patient's own cells. In a study that will appear in the journal Nature and is receiving early online release, investigators from the Massachusetts General Hospital Center for Regenerative Medicine (MGH-CRM) and the Harvard Stem Cell Institute (HSCI), describe finding that an important cluster of genes is inactivated in induced pluripotent stem cells (iPSCs) that do not have the full development potential of embryonic stem cells.
Cigarette smoking is a major cause of illness and death worldwide. But it is a complex behavior, and how much people smoke, how hard they find it to quit, and the impact of long-term smoking on health varies greatly among individuals. A substantial portion of this variability is genetic. Two years ago, deCODE discovered the first common, single-letter variation in the sequence of the human genome, on chromosome 15q25, associated with nicotine addiction and risk of lung cancer.
Knocking genes out of action allows researchers to learn what genes do by seeing what goes wrong without them. University of Utah biologists pioneered the field. Mario Capecchi won a Nobel Prize for developing knockout mice. Kent Golic found a way to cripple fruit fly genes. Now, biologist Erik Jorgensen and colleagues have devised a procedure for knocking out genes in nematode worms.
