Chromosome 4 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 4, one copy inherited from each parent, form one of the pairs. Chromosome 4 spans more than 191 million DNA building blocks (base pairs) and represents more than 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 4 likely contains between 1,300 and 1,600 genes.

Genes on chromosome 4 are among the estimated 20,000 to 25,000 total genes in the human genome.

SORT1 pathway holds promise as new target for therapeutic intervention for LDL cholesterol reduction

The true power of genomic research lies in its ability to help scientists understand biological processes, particularly those that - when altered - can lead to disease. This power is demonstrated dramatically in a pair of papers published today in the journal Nature. In the first, a global team of researchers describes 95 different variations across the genome that contribute in different degrees to alterations in blood cholesterol and triglyceride levels in multiple human populations. In the second report, close examination of just one of these common variants not only reveals the involvement of an unexpected genetic pathway in lipid metabolism but also provides a blueprint for using genomic findings to unravel biological connections between lipid levels and coronary heart disease.

People insensitive to quinine's bitter taste may have varied absorption, metabolization capabilities: Study

Some people find quinine to be bitter while others can drink it like water. Now, scientists from the Monell Center and collaborators report that individual differences in how people experience quinine's bitterness are related to underlying differences in their genes.The findings, published online in the journal Human Molecular Genetics, demonstrate that genetic variation in regions of DNA that encode bitter taste receptors predicts a person's perception of bitterness from quinine.

Genetics research team discovers new recurrent translocations

A genetics research team based at The Children's Hospital of Philadelphia continues to discover recurrent translocations—places in which two chromosomes exchange pieces of themselves. As many as 1 in 600 persons carry balanced chromosome translocations, which involve no loss or gain of DNA. Most such people appear healthy, but may have a child with abnormal chromosome composition and disabilities resulting from disrupted, extra or missing copies of genes.

Study on link between SNP and concentrations of serum creatinine

Scientists at deCODE genetics and colleagues at Radboud University in the Netherlands today describe how the impact of a single letter variation in the sequence of the human genome conferring risk of kidney disease varies with age and with the onset of other diseases. The study provides independent confirmation of the association made in an earlier study between a version of the the SNP, located on chromosome 16p12, and risk of chronic kidney disease. It also confirmed the link between the SNP and concentrations of serum creatinine, a key indicator of kidney function.

Scientists identify new targets to develop treatment for HD

Scientists at the Buck Institute for Age Research have discovered that a particular family of enzymes are involved in the breakdown of proteins that modify the production of toxic fragments that lead to the pathology of Huntington's disease. These enzymes, matrix metalloproteinases, provide new targets for drug therapies for the disease - targets that have already been shown to respond to cancer drugs currently in clinical development.

Researchers discover new gene regulation, DNA behavior of breast cancer cells

Cancer researchers have discovered a previously unknown type of gene regulation and DNA behavior in breast cancer cells that may lead to better insight about environmental exposure to estrogen-like compounds. A new study, published in the journal Genome Research by researchers at The Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James), provides the first evidence that cells can regulate many genes at once by looping their DNA, contributing to cancer when it goes awry. In this study, the gene regulation was discovered in breast cancer cells as a response to the hormone estrogen and resulted in the silencing of 14 genes at one time.

AMPK may regulate epigenetic mechanism: Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

Scientists identify potential disease genes in humans and mice

An international consortium of scientists of Helmholtz Zentrum München and the University of Toronto has identified previously unknown potential disease genes in humans and mice. Genes on the X chromosome, which regulate embryonic development, are the focus of the current publication in the renowned journal Genome Research. Men have only one X chromosome, and therefore mutations on this chromosome disproportionately affect males, frequently leading to serious diseases such as hemophilia, muscular dystrophy and mental retardation.
