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.
A protein known as WWP2 appears to play a key role in tumor survival, a research team headed by a scientist at The University of Texas MD Anderson Cancer Center reports in an advance online publication of Nature Cell Biology.
A protein associated with Alzheimer's disease clogs several motors of the cell transport machinery critical for normal cell division, leading to defective neurons that may contribute to the memory-robbing disease, University of South Florida researchers report.
Researchers have developed an effective technique that uses gene therapy on stem cells to correct chronic granulomatous disease in cell culture, which could eventually serve as a treatment for this rare, inherited immune disorder, according to a study published in Blood, the Journal of the American Society of Hematology.
Gene Security Network announced today that they have received a $2 million grant from the National Institutes of Health to conduct a clinical trial applying Parental Support technology for non-invasive prenatal diagnosis.
Dana-Farber Cancer Institute scientists have discovered new details of how cancer cells escape from tumor suppression mechanisms that normally prevent these damaged cells from multiplying. They also demonstrated a potential link between this cell proliferation control mechanism and the cognitive deficits caused by Down syndrome.
Max Planck scientists uncover surprising genetic links. Scientists from the Max Planck Institute for Psychiatry in Munich have compared the genomes of a total of 4,088 patients and 11,001 healthy control subjects from all over the world and identified a new risk gene variant for depression.
A study of DNA rearrangements in roundworm chromosomes may offer new insight into large-scale genome duplications that occur in developing tumors.
In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality.
Whitehead Institute Director David Page has been named a recipient of the 2011 March of Dimes Prize in Developmental Biology. The prize honors Page's groundbreaking body of research on the human Y chromosome.
Researchers at the University of Pennsylvania School of Medicine are delving into the details of the complex structure at the ends of chromosomes.
According to the latest study in the journal Nature, researchers from Imperial College London and the University of Washington, Seattle found that after making specific genetic changes to a few mosquitoes and then allowing them to breed could eventually dramatically reduce the spread of the deadly disease malaria.
Two new studies highlight the power of sequencing cancer patients' genomes as a diagnostic tool, helping doctors decide the best course of treatment and researchers identify new cancer susceptibility mutations that can be passed from parent to child.
Scientists have carried out the first ever genome scan for womb cancer and discovered a genetic region that reduces risk of the disease, according to a study published in Nature Genetics.
An enzyme essential for DNA replication and repair in humans works in a way that might be exploited as anti-cancer therapy, say researchers at The Scripps Research Institute and Lawrence Berkeley National Laboratory.
A Short Comparative Genomic Hybridisation method has been developed to carry out preimplantation genetic screening by analysing all chromosomes and transferring selected embryos to the recipient uterus in the same in vitro fertilisation cycle. This eliminates the need to freeze them.
For years, researchers in genome stability have observed that several neurodegenerative diseases-including Huntington's disease-are associated with cell-killing proteins that are created during expansion of a CAG/CTG trinucleotide repeat.
DNA's role as the master blueprint of the cell means that even small sequence changes can have catastrophic consequences. For this reason, much of our understanding of cancer development comes from studying how cells copy DNA and repair sequence errors--and how these processes can go wrong.
Researchers have zoomed in on mouse chromosomes to map hotspots of genetic recombination - sites where DNA breaks and reforms to shuffle genes. The findings of the scientists at the National Institutes of Health and Uniformed Services University of Health Sciences (USU) have the potential to improve the detection of genes linked to disease and to help understand the root causes of genetic abnormalities.
Tumor suppressor genes normally control the growth of cells, but cancer can spring up when these genes are silenced by certain chemical reactions that modify chromosomes.
Researchers at the University of Michigan Comprehensive Cancer Center have identified a genetic anomaly that may drive the aggressive spread of a rare subset of prostate cancers.
