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.

Additional chromosomal abnormalities prognostic for CML

Additional chromosomal abnormalities can be used to create two prognostic groups of patients with chronic myeloid leukaemia, suggests research published in Blood.

Researchers determine mutations in RERE gene can cause many features linked with 1p36 deletions

One in 5,000 babies is born missing a small amount of genetic material from the tip of chromosome 1, a region called 1p36. Missing genes in the 1p36 region is a relatively common cause of intellectual disability.

Putative male-determining gene discovery could help develop strategies to combat malaria

A group of scientists, including one from the University of California, Riverside, have discovered a long-hypothesized male determining gene in the mosquito species that carries malaria, laying the groundwork for the development of strategies that could help control the disease.

Embryos with abnormalities in initial stages of pregnancy may grow into healthy babies

Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down's syndrome, suggests new research carried out in mice at the University of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing - and in many cases completely fixing - the embryo.

Researchers use novel technology to sequence Y chromosome in malaria spreading mosquitoes

A team of researchers with the Fralin Life Science Institute at Virginia Tech, working with a large international consortium, has sequenced the Y chromosome--the genetic driver of sex-determination and male fertility-- in a family of malaria spreading mosquitoes.

Shugoshin protein maintains proper gene expression in subtelomeres

A research group discovered a new function of the chromosomal terminus, which may lead to the clarification of the mechanism for developing abnormal telomere structure such as multiple malformation and mental retardation.

UT Southwestern scientists discover mutation that causes X-linked reticulate pigmentary disorder

UT Southwestern Medical Center researchers have discovered a mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

SLU scientist describes several tactics that can help cells overcome lesions

In a recent review paper published in Nature Structural & Molecular Biology, SLU scientist Alessandro Vindigni, Ph.D., describes the strategies cells use when their DNA faces replication stress, challenges that may derail a cell's ability to reproduce.

Genetic syndrome may underlie some Parkinson's cases

Rare deletions at chromosome 22q11.2 are present at an increased rate in patients with Parkinson's disease, researchers report in The Lancet Neurology.

Study uncovers role of small RNAs in fine-tuning egg development

All multicellular organisms that reproduce sexually rely on eggs to support early life. Researchers at University of California, San Diego School of Medicine and Ludwig Cancer Research used the tiny roundworm C. elegans as a model to better understand how eggs enable embryonic development, using only the materials already present in them.

Scientists identify gene associated with cleft lip and palate

Leading scientists have identified an important gene that is associated with cleft lip and palate.Experts say the discovery is a step closer to understanding how this birth defect arises, and will help in the development of medical approaches to prevent the disfiguring condition.

Virus-generated DNA lurking between human genes, show research

Think your DNA is all human? Think again. And a new discovery suggests it's even less human than scientists previously thought.

Researchers elucidate how cells are blind to chromosome cohesion defects

Research led by Raquel Oliveira, group leader at Instituto Gulbenkian de Ciência, has elucidated how cells are almost blind to chromosome cohesion defects.

Research: X and Y DNA swapping may occur more often than previously thought

It turns out that the rigid "line in the sand" over which the human sex chromosomes---the Y and X--- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often.

PERK inhibition can be a promising therapeutic strategy for neurodegenerative diseases

A major challenge in the field of neurodegeneration is the unclear understanding of neuronal dysfunction. Elucidation of these patho-mechanisms could result in the identification of novel therapeutic targets. In this article, Bell et al. present an exhaustive literature review highlighting the endoplasmic reticulum (ER) kinase PERK as a crucial contributor to systemic and neurodegenerative disorders.

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.

Researchers identify new mutation responsible for spinocerebellar ataxia

Using the genetic information of two different families with three generations of disease, researchers have identified a new mutation responsible for a degenerative and ultimately fatal movement disorder. Through induced pluripotent stem cell techniques, researchers also grew neurons from one patient in the laboratory to be used in future experiments.

15 Mar 2016

Researchers develop new technique to create naïve pluripotent stem cells

Scientists at the University of Cambridge have for the first time shown that it is possible to derive from a human embryo so-called 'naïve' pluripotent stem cells - one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.

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.
