Chromosome 11 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 11, one copy inherited from each parent, form one of the pairs. Chromosome 11 spans about 134 million DNA building blocks (base pairs) and represents between 4 percent and 4.5 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 11 likely contains about 1,500 genes. More than 150 of these genes provide instructions for making olfactory receptors, which are proteins that are used to detect different smells.

Genes on chromosome 11 are among the estimated 20,000 to 25,000 total genes in the human genome.

Variations in genome’s 'dark matter' region can make patients susceptible to inflammatory diseases

A study led by researchers at the Babraham Institute in collaboration with the Wellcome Sanger Institute has uncovered how variations in a non-protein coding 'dark matter' region of the genome could make patients susceptible to complex autoimmune and allergic diseases such as inflammatory bowel disease.

Cardiovascular and Alzheimer's disease share common genetics in some individuals, study shows

Genetics may predispose some people to both Alzheimer's disease and high levels of blood lipids such as cholesterol, a common feature of cardiovascular disease, according to a new study by an international team of researchers led by scientists at UC San Francisco and Washington University School of Medicine in St. Louis.

MGH researchers explore how genetic abnormality in Ewing sarcoma unleashes tumor growth

A Massachusetts General Hospital research team has used epigenome editing tools to investigate how the genetic abnormality that drives Ewing sarcoma - the second most common bone cancer in children and young adults - unleashes tumor growth.

$Study uncovers genomic targets in refractory neuroblastoma$

Study uncovers genomic targets in refractory neuroblastoma

Neuroblastoma (NB) is the most common solid tumor found in children. It starts in some very early forms of nerve cells found in the embryo or fetus.

Duke researchers map evolution of sex chromosomes in fungus linked to human disease

Biologically speaking, nearly every species on Earth has two opposite sexes, male and female. But with some fungi and other microbes, sex can be a lot more complicated.

Northwestern Medicine scientists identify targeted molecular therapy that halts childhood leukemia

Northwestern Medicine scientists have discovered the genetic driver of a rare and lethal childhood leukemia and identified a targeted molecular therapy that halts the proliferation of leukemic cells.

Researchers create first mouse model for common form of infant leukemia

After nearly two decades of unsuccessful attempts, researchers from the University of Chicago Medicine and the Cincinnati Children's Hospital Medical Center have created the first mouse model for the most common form of infant leukemia.

Anti-anxiety drug reduces autistic features in Jacobsen syndrome mice

About half of children born with Jacobsen syndrome, a rare inherited disease, experience social and behavioral issues consistent with autism spectrum disorders. Researchers at University of California, San Diego School of Medicine and collaborators developed a mouse model of the disease that also exhibits autism-like social behaviors and used it to unravel the molecular mechanism that connects the genetic defects inherited in Jacobsen syndrome to effects on brain function.

Discovery could lead to better therapies for people with obsessive compulsive disorder

Research led by investigators in veterinary and human medicine has identified genetic pathways that exacerbate severity of canine compulsive disorder in Doberman pinschers, a discovery that could lead to better therapies for obsessive compulsive disorder in people.

Researchers identify first gene that causes common form of mitral valve prolapse

An international research collaboration led by Massachusetts General Hospital investigators has identified the first gene in which mutations cause the common form of mitral valve prolapse (MVP), a heart valve disorder that affects almost 2.5 percent of the population.

Understanding genetic machinery that drives malignant pediatric adrenocortical tumors

In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the "genomic landscape" of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.

Study could lead to potential therapeutic targets to treat Ewing Sarcoma

A University of Colorado Cancer Center study published in the journal PLoS One finds alterations in expression of genes PIK3R3 and PTEN, more commonly observed in adult tumors, in the rare, young-adult bone cancer Ewing Sarcoma, potentially offering ways to improve therapy.

4 Feb 2015

Research findings may lead to new treatment strategies for Ewing sarcoma

The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes - both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing. These findings by Massachusetts General Hospital investigators, published in the November issue of Cancer Cell, may lead to new therapies targeting these aberrant mechanisms.

UCSB researchers explore genetic underpinnings of nerve-cell spacing

The functional organization of the central nervous system depends upon a precise architecture and connectivity of distinct types of neurons.

Pediatric Cancer Genome Project identifies genetic alteration in brain tumor ependymoma

The St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project has identified the most common genetic alteration ever reported in the brain tumor ependymoma and evidence that the alteration drives tumor development. The research appears February 19 as an advanced online publication in the scientific journal Nature.
