Researchers map signaling networks that control neuron function

01-28-2008 · EurekAlert!

In the first large-scale proteomics study of its kind, researchers at the University of California-San Diego School of Medicine have mapped thousands of neuronal proteins to discover how they connect into complex signaling networks that guide neuron function. Their research -- using quantitative mass spectrometry, computational software and bioinformatics to match the proteins to their cellular functions -- may lead to a better understanding of brain development, neurodegenerative diseases, and spinal cord regeneration.

    University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate -- and are apparently evolving -- in animals in response to climate change. The map will allow researchers to narrow their focus to identify specific genes that control the seasonal development of animals.

  4. New research discovers independent brain networks control human walking
    08-07-2007 · EurekAlert!
    In a study published in the August issue of Nature Neuroscience, researchers at the Kennedy Krieger Institute in Baltimore, Md., found that there are separate adaptable networks controlling each leg and there are also separate networks controlling leg movements, e.g., forward or backward walking. These findings are contrary to the currently accepted theory that leg movements and adaptations are directed by a single control circuit in the brain.

  5. Scientists discover new role for miRNA in leukemia
    12-09-2007 · EurekAlert!
    Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia from its more treatable chronic phase to a life-threatening phase, called blast crisis.Furthermore, they discovered an entirely new function for these molecules. The researchers show that microRNAs can sometimes directly control a protein’s function -- not just whether or not the protein is made by the cell, as has been believed.

    04-20-2007 · EurekAlert!
    Yale School of Medicine and University of Crete School of Medicine researchers report in Cell April 20 the first evidence of a molecular mechanism that dynamically alters the strength of higher brain network connections involved in working memory. This discovery may help the development of drug therapies for the cognitive deficits of normal aging, and for cognitive changes in schizophrenia, bipolar disorder, or attention deficit hyperactivity disorder (ADHD).

  9. U-M scientists find new causes for neurodegeneration
    10-24-2007 · EurekAlert!
    Diseases that cause neurons to break down, such as Alzheimer's, continue to be elusive to scientists and resistant to treatments. A new finding from University of Michigan researchers demonstrates an unpredicted link between a virtually unknown signaling molecule and neuron health. In a study released in PNAS this week, Lois Weisman connects the loss of this molecule to massive neurodegeneration in the brain, which plays a key role in the survival of nervous system cells.

  10. Researchers Uncover Critical Player In Cell Communication
    10-06-2006 · ScienceDaily
    Johns Hopkins researchers have teased out the function of a protein implicated in Williams-Beuren syndrome, a rare cognitive disorder associated with overly social behavior and lack of spatial awareness. Called TFII-I, or TF "two eye," the protein long known to help control a cell's genes also controls how much calcium a cell takes in, a function critical for all cells, including nerves in the brain. The study will be published this week in Science.
