Chromosome 7 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 7, one copy inherited from each parent, form one of the pairs. Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 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 7 likely contains about 1,150 genes.

Genes on chromosome 7 are among the estimated 20,000 to 25,000 total genes in the human genome.

MGH study points toward potential strategy for treating X-linked disorders

A study from a team of Massachusetts General Hospital (MGH) investigators points toward a potential strategy for treating X-linked disorders - those caused by mutations in the X chromosome - in females.

Study illustrates the role of alcohol in causing damage to DNA and increased cancer risk

A new study conducted by a group of researchers at MRC Laboratory of Molecular Biology, Cambridge revealed the significant role of alcohol in causing damage to DNA in stem cells and thereby increasing cancer risks. The study was funded by Cancer Research UK and the results were published in Nature.

$Study uncovers genomic targets in refractory neuroblastoma$

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.

Novartis announces FDA approval of its first and only CML therapy with TFR data in product label

Novartis announced today that the US Food and Drug Administration (FDA) approved the inclusion of Treatment-free Remission (TFR) data in the Tasigna® (nilotinib) US product label.

Having older brothers may increase the likelihood of being gay

Scientists have found a distinct pattern that having older brothers raise the chances of the younger sibling being gay. This effect has been termed the “fraternal birth order effect”. They explain the biological reason behind this propensity in their new study that was published this week in the journal PNAS.

Simple molecular test may help predict presence of high-grade pancreatic cancers

A report in The Journal of Molecular Diagnostics, describes a new simple molecular test to detect chromosomal abnormalities -- biomarkers known as telomere fusions--in pancreatic tumor specimens and pancreatic cyst fluids.

SLU scientists provide promising approach in designing new drugs for DMD

In a paper published in the Nature journal Scientific Reports, Saint Louis University researchers report that a new drug reduces fibrosis (scarring) and prevents loss of muscle function in an animal model of Duchenne muscular dystrophy (DMD), providing a promising approach in designing new medications for those suffering from DMD.

Study shows how interplay between two key enzymes promotes brain tumor growth

Study results revealed previously unknown interplay between two key enzymes and a novel understanding of how brain cancer tumors form and spread, according to researchers at The University of Texas MD Anderson Cancer Center.

Research shows how cells rebuild nucleus, organize genome after division

University of Bristol research has revealed how cells rebuild their nucleus and organise their genome when they divide - a discovery which could have major implications for understanding cancer and degeneration.

Leishmania genome study reveals the parasites adaptation to the environment

A new study, conducted by researchers from the Institut Pasteur in Paris and the Centre for Genomic Regulation (CRG) in Barcelona, have revealed that Leishmania adaptation is a consequence of reversible and frequent chromosomal amplifications.

Leishmania adaptation to environmental changes results from frequent chromosomal amplifications

Leishmaniasis is an important human and veterinary disease caused by Leishmania parasites that affect 12 million people in over 98 endemic countries. The disease is now emerging in Europe due to climate change and massive population displacement.

OBD presents results of immunotherapy studies at FNIH Biomarker Consortium Cancer Steering Committee’s annual meeting

Oxford BioDynamics Plc, a biotechnology company focused on the discovery and development of epigenetic biomarkers based on regulatory genome architecture, for use within the pharmaceutical and biotechnology industry, presented its latest results at the annual meeting of the Foundation for National Institute for Health Biomarker Consortium Cancer Steering Committee, held in Washington, DC on 6-7 November 2017.

New technique may reveal clues about role of centromeres in Down syndrome, other birth defects

Some scientists call it the "final frontier" of our DNA -- even though it lies at the center of every X-shaped chromosome in nearly every one of our cells.

Aging tests disagree with one another

Whether it's an on-line quiz, a $300 chromosome test or an $800 blood panel, a lot of people seem to be interested in whether they're aging faster or slower than their chronological age would suggest.

Russian scientists uncover previously unknown effect of leukemia drug

Researchers from RUDN University and Institute of Biomedical Chemistry of the Russian Academy of Sciences have identified an alternative mechanism for the effective antitumor drug -- an enzyme called L-asparaginase.

KU Leuven researchers unravel how cell division timer works

Human cells use a timer to divide: each cell gets at least 30 minutes to divide its genetic material between the nuclei of two daughter cells.

Research casts light on how chromosomes 'cheat' for chance to get into a sex cell

Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete -- a sperm or an egg -- each copy has a 50-50 shot at being passed on. But the reality isn't so clearcut.

Scientists identify treatments that may restore brain function to autism patients

Scientists have identified a pair of treatments that may restore brain function to autism patients who lack a gene critical to maintaining connections between neurons, according to a study from the Peter O'Donnell Jr. Brain Institute at UT Southwestern Medical Center.

Our chromosomes also wrinkle with age, research shows

Grey hair, wisdom, and wrinkles on our skin mark us as we age, but it's the more subtle changes beneath the surface that make us old. Now, researchers have discovered that our chromosomes also wrinkle with age, changing how our immune system renews itself.
