Gene News and Research RSS Feed - Gene News and Research

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

New mouse model shows how mutated gene impairs neuronal development in individuals with autism

New mouse model shows how mutated gene impairs neuronal development in individuals with autism

Geneticists at Heidelberg University Hospital's Department of Molecular Human Genetics have used a new mouse model to demonstrate the way a certain genetic mutation is linked to a type of autism in humans and affects brain development and behavior. [More]
Researchers identify molecular switch that controls inflammatory processes in aging-related disorders

Researchers identify molecular switch that controls inflammatory processes in aging-related disorders

A study led by Massachusetts General Hospital (MGH) investigators has identified what appears to be a molecular switch controlling inflammatory processes involved in conditions ranging from muscle atrophy to Alzheimer's disease. [More]
Study: Hedgehog cell signaling pathway may play role in breast cancer metastasis

Study: Hedgehog cell signaling pathway may play role in breast cancer metastasis

Molecules called long non-coding RNAs (lncRNAs) have been implicated in breast cancer but exactly why they cause metastasis and tumor growth has been little understood…until now. [More]
New study shows that brain’s ability to manage stress depends on brain protein

New study shows that brain’s ability to manage stress depends on brain protein

The brain's ability to effectively deal with stress or to lack that ability and be more susceptible to depression, depends on a single protein type in each person's brain, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published November 12 in the journal Nature.

Genetic testing, risk factor assessment could improve prevention strategies for breast cancer

Genetic testing, risk factor assessment could improve prevention strategies for breast cancer

Scientists used mathematical models to show that analysing genetic data, alongside a range of other risk factors, could substantially improve the ability to flag up women at highest risk of developing breast cancer. [More]
Rare gene mutation linked to lower cholesterol levels, reduced risk of heart attack

Rare gene mutation linked to lower cholesterol levels, reduced risk of heart attack

Rare mutations that shut down a single gene are linked to lower cholesterol levels and a 50 percent reduction in the risk of heart attack, according to new research from Washington University School of Medicine in St. Louis, the Broad Institute at Massachusetts Institute of Technology and Harvard, and other institutions.

Estrogen plays key role in regulating blood pressure, LDL cholesterol levels

Estrogen plays key role in regulating blood pressure, LDL cholesterol levels

What makes some women more susceptible to heart disease than others? To help answer that question, researchers at Western University's Robarts Research Institute have identified that an estrogen receptor, previously shown to regulate blood pressure in women, also plays an important role in regulating low-density lipoprotein (LDL) cholesterol levels.
