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.

Scientists identify more aggressive chemotherapy treatment for childhood brain cancer

Down syndrome may hold important clues to onset of Alzheimer's disease

At first glance, Down syndrome and Alzheimer's disease, two severe brain abnormalities, may seem to have little in common. Down syndrome is a hereditary disease, the source of which has long been recognized--a triplication of chromosome 21.

Researchers sequence two selfish genes in the fungus Neurospora intermedia

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful.

Genetic link to erectile dysfunction discovered

According to a new study there may be a genetic link to erectile dysfunction. This is the first time that such as connection has been made and this could mean that newer avenues of treatment could be explored for erectile dysfunction, explain the researchers.

Study highlights opposite effects of gene following different types of environmental events

Researchers have discovered that the same gene which increases your risk of depression following financial stress as you grow older also reduces your chance of depression associated with friendship and relationships stresses when young- your social network.

Research reveals how critical oocyte quality control process works

Females are born with a finite number of eggs that are steadily depleted throughout their lifetime. This reserve of eggs is selected from a much larger pool of millions of precursor cells, or oocytes, that form during fetal life.

New framework combines three existing methods to find cancer cell mutations

Cancer cells often have mutations in their DNA that can give scientists clues about how the cancer started or which treatment may be most effective. Finding these mutations can be difficult, but a new method may offer more complete, comprehensive results.

Family genetic background essential for understanding autism progression

Whether an individual develops a neurodevelopmental disorder like autism or ADHD and the severity of that disorder depends on genetic changes beyond a single supposedly disease-causing mutation.

Researchers describe novel mechanism that links epigenetic change to translational control

Understanding how memories form and are retrieved has applications to psychiatric, neurological and neurodegenerative disorders, and may be helpful to attenuate maladaptive memories in psychiatric disorders.

Short telomeres could be independent risk factor for age-related functional decline

Elderly people with short chromosome caps, or telomeres, are more likely to have difficulty performing daily activities such as carrying groceries, climbing stairs and walking, finds a new study of more than 1,200 people from five European countries.

Novel method using big data tools shows promising routes for research

A group of researchers affiliated to the University of São Paulo - campus Ribeirão Preto, Brazil, used big data tools such as data mining and network analysis to develop a method to help scientists and companies identify technological routes, trends and partnerships in any knowledge area. For this purpose, it collected information from patent databases around the world.
