Chromosome 3 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 3, one copy inherited from each parent, form one of the pairs. Chromosome 3 spans almost 200 million base pairs (the building blocks of DNA) and represents approximately 6.5 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 3 likely contains between 1,100 and 1,500 genes.

Genes on chromosome 3 are among the estimated 20,000 to 25,000 total genes in the human genome.

Scientists develop new mathematical model to understand CML better

Doctors can now understand better chronic myeloid leukaemia (CML), including how it responds to therapy, thanks to a new mathematical model for the disease, developed by scientists in Portugal, Belgium and the United States. The work, to be published in the June edition of the journal Haematologica, also reveals that current therapies - which are not believed to cure CML - with the right protocol can actually get rid of the disease, and provides guidelines on how to do that.

Cancer genomes: Distinguishing between 'driver' and 'passenger' mutations

A new study of mutations in cancer genomes shows how researchers can begin to distinguish the 'driver' mutations that push cells towards cancer from the 'passenger' mutations that are a by-product of cancer cell development. The study also shows that at least one in nine genes can be removed without killing human cells.

Most genetic abnormalities shared across multiple cancers

An international team of researchers has created a genome-scale map of 26 different cancers, revealing more than 100 genomic sites where DNA from tumors is either missing or abnormally duplicated compared to normal tissues. The study, the largest of its kind, finds that most of these genetic abnormalities are not unique to one form of cancer, but are shared across multiple cancers. The work appears in the February 18 issue of the journal Nature.

Study analyzes genome and exome sequence data from hunter-gatherer participants of South Africa

In a study published online today in Nature, a team of researchers from Penn State University and the University New South Wales present the complete genome sequences of an indigenous hunter-gatherer from the Kalahari Desert and a Bantu from southern Africa, along with three additional whole exome sequences of Kalahari hunter-gatherers.

Novartis' Tasigna capsules granted priority review by FDA for treatment of adult patients with Ph+ CML

Novartis announced today that Tasigna® (nilotinib) 200 mg capsules has been granted priority review by the US Food and Drug Administration for the treatment of adult patients with newly diagnosed Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML) in chronic phase.

Johns Hopkins Kimmel Cancer Center scientists develop genome-based blood tests for cancer

Scientists at the Johns Hopkins Kimmel Cancer Center have used data from the whole genome sequencing of cancer patients to develop individualized blood tests they believe can help physicians tailor patients' treatments. The genome-based blood tests, believed to be the first of their kind, may be used to monitor tumor levels after therapy and determine cancer recurrence.

Researchers have traced protein that stops cells from becoming cancerous

In the dominoes that make up human cells, researchers at the University of Michigan Comprehensive Cancer Center have traced another step of the process that stops cells from becoming cancerous.

Researchers find new risk factor for early-onset dementia

Examining brain tissue from over 500 individuals in 11 countries, researchers from the University of Pennsylvania School of Medicine and the Children's Hospital of Philadelphia, and colleagues found a new risk factor for the second-most-common cause of early-onset dementia after Alzheimer's disease.

New research finds sensory cortex develops late in fragile X syndrome defect

Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch - even from their parents?

Scientists uncover new gene that could help save sight of patients with inherited blindness

The international research team led by the University of Leeds found that the TSPAN12 gene is faulty in patients with a disease known as FEVR (Familial Exudative Vitreoretinopathy), which affects the development of the eye.

Study shows cellular circuitry is more complex than previously thought

Using an elaborate sleuthing system they developed to probe how cells manage their own division, Johns Hopkins scientists have discovered that common but hard-to-see sugar switches are partly in control.

Results validating performance of GSN’s proprietary Parental Support technology published

Gene Security Network, Inc (GSN) today announced that Human Reproduction published results validating the exceptional performance of GSN’s proprietary Parental SupportTM technology over existing methods to detect chromosome abnormalities during in vitro-fertilization (IVF).

Defective chromosome cause of severe obesity

A new cause of obesity due to a defect on chromosome 16 has just been discovered. It is thought to explain close to 1% of obesity cases. For carriers of the defect, the risk of becoming overweight is 50 times higher. This research is the result of close cooperation between the team of Professor Froguel, a CNRS researcher, in Lille, and colleagues at Imperial College in London and Vaudois University Hospital in Lausanne, with the support of ten other European research groups. The findings of the study are to be published in Nature on February 4, 2010.

New research shows tumor suppressor p53 prevents cancer progression in cells

Cells missegregate a chromosome approximately once every hundred divisions. But don't be too alarmed: new research in the Journal of Cell Biology shows that the tumor suppressor p53 limits the growth of cells with incorrect numbers of chromosomes and prevents their progression toward cancer.

CAMH signs licensing agreement to develop and market genetic test for degenerative muscle disorder

The Centre for Addiction and Mental Health (CAMH) has signed a licensing agreement with a Massachusetts firm to develop and market an innovative genetic test for a recently identified degenerative muscle disorder. The disorder tends to strike adults in their early 30s.

Down Syndrome, menopause, dementia and death

Women experiencing an early onset of menopause could develop dementia at a younger age. Research by Tonnie Coppus of Erasmus MC has indicated this. She studied women with Down Syndrome, who are known to have an early onset of menopause. The results of her research can be translated to apply to the general population. Her results will be published in the Journal of Alzheimer Disease today.
