Researchers find gene mutation mechanism that cause mitochondrial diseases

Scientists have discovered a new cause of spastic ataxia, and believe this cause is also a trigger for other mitochondrial diseases neurological disorders that can lead to serious coordination, growth, visual, speech, and muscle defects.

Research on Reaper protein provides new treatment strategies for cancer

Our cells live ever on the verge of suicide, requiring the close attention of a team of molecules to prevent the cells from pulling the trigger. This self-destructive tendency can be a very good thing, as when dangerous precancerous cells are permitted to kill themselves, but it can also go horribly wrong, destroying brain cells that store memories, for instance. Rockefeller University scientists are parsing this perilous arrangement in ever finer detail in hopes that understanding the basic mechanisms of programmed cell death, or apoptosis, will enable them eventually to manipulate the process to kill the cells we want to kill and protect the ones we don't.

Drugs that restore mitochondria function may treat Alzheimer's disease at early stages: Research

Before Alzheimer's patients experience memory loss, the brain's neurons have already suffered harm for years. A new study in mouse models by researchers at Columbia University Medical Center has found that the brain's mitochondria, the powerhouses of the cell, are one of the earliest casualties of the disease. The study, which appeared in the online Early Edition of PNAS, also found that impaired mitochondria then injure the neurons' synapses, which are necessary for normal brain function.

Study finds boosting mitochondria may delay onset of Parkinson's disease

In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating effects on brain cells, which consume roughly 20 percent of the body's energy despite making up only 2 percent of body weight.

Parkinson’s disease pathology breakthrough

Researchers have found that brain cells of people with early Parkinson's disease have damaged powerhouses. In a new study they have identified 10 groups of gene sets related to the energy production problems in the brain cells of these people.

Amino acid mixture increases survival in mice

When mice are given drinking water laced with a special concoction of amino acids, they live longer than your average mouse, according to a new report in the October issue of Cell Metabolism, a Cell Press publication. The key ingredients in the supplemental mixture are so-called branched-chain amino acids, which account for 3 of the 20 amino acids (specifically leucine, isoleucine, and valine) that are the building blocks of proteins.

Neuro-Biotech introduces biomarker for progressive clinical investigation on Alzheimer's Disease

Neuro-Biotech Corporation introduces a Neuro-biomarker which is linked to a series of Neuro-Bio tests. This will permit to understand the science behind them and how they each will contribute to a progressive clinical investigation involving the input and output of the brain.

UCLA receives contract to study proteins involved in cardiovascular disease development

UCLA has received a five-year, $12.5 million contract award from the National Heart, Lung and Blood Institute to spearhead an international consortium of medical experts that will study proteins that may be involved in the development of cardiovascular disease.

Study reveals molecular steps for pneumonia therapy

A structural molecule and the cellular pump that regulates its levels influence the severity of pneumonia and could provide new ways of treating the lung infection, which is a leading cause of hospitalization and death, according to scientists at the University of Pittsburgh and the University of Iowa. Their findings are available online in Nature Medicine.

Alpha-synuclein protein in Parkinson's disease inhibits autophagy: Research

A protein linked to Parkinson's disease may cause neurodegeneration by inhibiting autophagy-the process in which cells digest some of their contents-according to a study in the September 20 issue of the Journal of Cell Biology

Researches discover reducing tau protein level can prevent Αβ protein transport in Alzheimer’s disease

Amyloid beta (Αβ) proteins, widely thought to cause Alzheimer's disease (AD), block the transport of vital cargoes inside brain cells. Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that reducing the level of another protein, tau, can prevent Aβ from causing such traffic jams.

Cachexia reduces function and changes muscle structure of heart in mice with colon cancer

The wasting disease associated with some cancers that is typically seen affecting skeletal muscles can also cause significant damage to the heart, new research in mice suggests.

Estradiol prevents vascular permeability following hemorrhagic shock: Study

A study published in the September 2010 issue of SHOCK by Dr. Ed W. Childs and colleagues at Scott & White Healthcare looks at how female versus male rats fared after suffering a trauma and subsequent hemorrhagic shock who were given Estradiol (estrogen). In the study, the Estradiol prevented vascular permeability following hemorrhagic shock.

Critical mechanistic link between mutant protein and disease pathogenesis in ALS uncovered

New research uncovers what may be a primary neuron-damaging insult that occurs in an inherited form of a devastating neurodegenerative disorder. The study, published by Cell Press in the August 26th issue of the journal Neuron, describes a critical mechanistic link between a mutant protein and disease pathogenesis in an animal model of amyotrophic lateral sclerosis (ALS).

Scientists create novel map of lipid locations in single cell

In real estate, location is everything. The same might be said of lipids - those crucial cellular fats and oils that serve as building blocks for cells and as key energy sources for the body.In a paper published in the September issue of the Journal of Lipid Research, a team of scientists, led by researchers at the University of California, San Diego School of Medicine, has mapped for the first time the actual locations of specific lipids within a single cell.

NCF announces formal disease model for Chronic Fatigue Syndrome

The National CFIDS Foundation Inc., of Needham Mass, has announced its formal disease model for Chronic Fatigue Syndrome (CFS) also known as Chronic Fatigue Immune Dysfunction Syndrome (CFIDS) as well as Myalgic Encephalomyelitis (ME). According to the NCF, a subgroup of patients with CFS fit a unique disease profile based on a model for a radioactive toxin.

Scientists identify role of PNPASE in regulating RNA import into mitochondria

Researchers at UCLA's Jonsson Comprehensive Cancer Center and the departments of Chemistry and Biochemistry and Pathology and Laboratory Medicine have uncovered a role for an essential cell protein in shuttling RNA into the mitochondria, the energy-producing "power plant" of the cell. The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria remain poorly understood.
