How mitochondrial genes are passed from mother to child

How mitochondrial genes are passed from mother to child

This finding helps answer some long-standing questions about how mitochondria-linked gene mutations are inherited. Gene mutations in cell mitochondria can cause several diseases, including forms of cancer, diabetes, infertility and neurodegenerative di…

Novel regulatory molecules called mirror-microRNAs control multiple aspects of brain function

Novel regulatory molecules called mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are — from the color of our hair to our vulnerability to certain diseases — but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of mole…

Fried food risks: Toxic aldehydes detected in reheated oil

| February 22, 2012

Researchers have been the first to discover the presence of certain aldehydes in food, which are believed to be related to some neurodegenerative diseases and some types of cancer. These toxic compounds can be found in some oils, such as sunflower oil,…

Neurodegenerative diseases: Ring-like structure found in ‘elongator’ protein complex

Neurodegenerative diseases: Ring-like structure found in ‘elongator’ protein complex

| February 20, 2012

A ring-like structure found in a protein complex called ‘Elongator’ provides new clues to its tasks inside the cell and to its role in neurodegenerative diseases. It is the first three-dimensional structure of part of this complex.

New class of potential drugs inhibits inflammation in brain

New class of potential drugs inhibits inflammation in brain

| February 14, 2012

Scientists have identified a new group of compounds that may protect brain cells from inflammation linked to seizures and neurodegenerative diseases. The compounds block signals from EP2, one of the four receptors for prostaglandin E2, which is a hormo…

Why do cells age? Discovery of extremely long-lived proteins may provide insight into cell aging and neurodegenerative diseases

Why do cells age? Discovery of extremely long-lived proteins may provide insight into cell aging and neurodegenerative diseases

One of the big mysteries in biology is why cells age. Now scientists report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.
