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.
A novel, free, public online database opening this week should greatly speed efforts to find genes linked to increase risk of bipolar disorder.
Xenomics, Inc. has announced the issuance of its first European patent "Methods for detection of nucleic acid sequences in urine", EP 1634966 A2 that covers use of its proprietary transrenal nucleic acid technology in the area of prenatal diagnostics and genetic testing.
Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example.
In a dividing cell, chromosomes interact with cellular scaffolding - called spindle microtubules - in order to move themselves to opposite ends of the cell, ensuring that both daughter cells receive an exact copy of their parent cell's genetic material.
Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer.
Imagine the day when a routine visit to the family doctor includes a simple blood test to predict the risk for developing Alzheimer's disease (AD).
A new model for understanding how autism is acquired has been developed by a team of researchers led by Cold Spring Harbor Laboratory (CSHL) and Albert Einstein College of Medicine.
St. Jude investigators have used the lowly yeast to gain insights into how a dividing human cell ensures that an identical set of chromosomes gets passed on to each new daughter cell.
Scientists have moved a step closer to understanding how our genetic make-up can lead us to develop heart disease and to predicting who is most at risk.
Scientists at deCODE genetics ( NASDAQ:DCGN ) in collaboration with colleagues from Emory University today report the discovery of the first variant in the sequence of the human genome ever linked to risk of Restless Legs Syndrome (RLS) and Periodic Limb Movements (PLMs).
Pediatrics researchers at The Children's Hospital of Philadelphia and McGill University in Montreal have identified a gene variant that raises a child's risk for type 1 diabetes, formerly called juvenile diabetes.
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired.
The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.
Researchers have identified a new gene mutation linked to frontotemporal dementia, according to a study published in the July 10, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.
A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.
Chromosome disorders in sex cells cause infertility, miscarriage and irregular numbers of chromosomes (aneuploidy) in neonates.
A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.
Researchers at the Ontario Institute for Cancer Research and Cancer Care Ontario have successfully identified a specific genetic variation on chromosome 8 that is associated with colorectal cancer.
New treatments for childhood asthma could be in the pipeline following the discovery of a gene associated with the condition.
In a large-scale study conducted with 2,643 children, international researchers with the participation of the Department of Experimental Pneumology of Ruhr-University Bochum (RUB), Germany (Prof. Dr. Albrecht Bufe), have discovered a gene variant that contributes significantly to the risk of childhood asthma.
