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.

Mutations in a crucial gene responsible for chemotherapy failure in some blood cancer patients

Mutations in a crucial gene are the key reason that chemotherapy fails in some patients with blood cancer, a study by Nanyang Technological University, Singapore (NTU Singapore) and Singapore General Hospital (SGH) has found.

New study uncovers a mechanism of sleep in zebrafish

Why do humans spend a third of their lives sleeping? Why do animals sleep? Throughout evolution sleep has remained universal and essential to all organisms with a nervous system, including invertebrates such as flies, worms, and even jellyfish.

Scientists identify new gene that contributes to type 1 diabetes progression

When the pro-inflammatory pair, a receptor called CCR2 and its ligand CCL-2, get together, it increases the risk of developing type 1 diabetes, scientists report.

New application makes it possible to monitor the symptoms of people at risk for psychosis

A team from the UNIGE has developed an application that makes it possible to monitor the frequency and intensity of the symptoms of people at risk for psychosis on a daily basis, in order to be able to adapt their medical follow-up and determine the cause of the appearance of symptoms.

Rutgers study links genetic disorders to walking patterns

Rutgers researchers have linked the genetic disorders Fragile X and SHANK3 deletion syndrome – both linked to autism and health problems – to walking patterns by examining the microscopic movements of those wearing motion-sensored sneakers.

Research reveals the mechanisms of cardiac sex disparities at an early stage

Males and females differ in prevalence, treatment responses, and survival rates for a variety of diseases. For cardiac disease, women almost uniformly fare far worse than men. There are likely many reasons for this, and scientists at the University of North Carolina at Chapel Hill and Princeton University seemed to have found one deep inside cells before we're even born.

Researchers reveal the mechanism of artificial chromosome formation in C. elegans' embryos

A research team led by Dr Karen Wing Yee YUEN, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) formation in the embryos of the model organism Caenorhabditis elegans, a 1-mm long, transparent nematode.
