Bax factor that promotes cell death is also involved in regulating mitochondria behavior

New research led by UC Davis scientists provides insight into why some body organs are more susceptible to cell death than others and could eventually lead to advances in treating or preventing heart attack or stroke.

Contagious cancer repairs own genetic mutations

A curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science.

Slowing engines of mitochondria could extend life

In making your pro-longevity resolutions, like drinking more red wine and maintaining a vibrant social network, here's one you likely forgot: dialing down your mitochondria. It turns out that slowing the engines of these tiny cellular factories could extend your life-an observation relevant not only to aging research but to our understanding of how cells communicate with each another.

Scientists perform surgery on single cell to extract and examine mitochondria

Medical researchers who crave a means of exploring the genetic culprits behind a host of neuromuscular disorders may have just had their wish granted by a team working at the National Institute of Standards and Technology, where scientists have performed surgery on single cells to extract and examine their mitochondria.

AMPK activates autophagy by activating ATG1 enzyme

Researchers at the Salk Institute for Biological Studies have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free up essential molecular building blocks in times of need.

Researchers discover new molecular mechanism of Alzheimer's disease through protein interaction

Through a complex analysis of protein interactions, researchers from IRB Barcelona and the Joint Programme IRB-BSC have discovered new molecular mechanisms that may be involved in the development of Alzheimer's disease.

Over expression of transcription factor improves neurological function in HD transgenic mice models

Over expressing a transcription factor that promotes the increase in number of mitochondria greatly improves the neurological function of transgenic mice models for Huntington's disease, researchers today told the American Society of Cell Biology's 50th Annual Meeting in Philadelphia.

Research programs embody the promise of anti-aging medicine.

Sometimes the value of research lies as much in exposing false remedies as in discovering true breakthroughs. Scientists at the country's first school of gerontology and in laboratories around the University of Southern California do both, mindful of their responsibility to a society focused on healthful aging.

NIH awards Scripps Research $2.35M to study new treatment for obesity

The Scripps Research Institute has been awarded a $2.35 million grant from the National Institutes of Health to study a new way of treating obesity as part of a national consortium with the Dana-Farber Cancer Institute.

Reason behind recurrence of CLL in lymph nodes and bone marrow after chemotherapy

In research to be presented at the American Society of Hematology (ASH) annual meeting, investigators at Dana-Farber Cancer Institute in Boston offer a new explanation of why chronic lymphocytic leukemia (CLL) tends to recur in the lymph nodes and bone marrow after being cleared from the bloodstream by chemotherapy. Their findings will be reported during in an oral session on Monday, Dec. 6, at 4:45 p.m. in room 315 of the Orange County Convention Center.

Mitochondrial brain changes contribute to risk of Alzheimer's disease: Research

What are the earliest brain changes associated with the risk of developing Alzheimer's disease. A scientific report published in the October Journal of Alzheimer's Disease finds reduced activity of an energy-generating enzyme in deceased young adult brain donors who carry a common genetic risk factor for Alzheimer's disease.

Research could lead to new drug treatment for metabolic diseases

A team of Harvard School of Public Health (HSPH) scientists report finding a molecular "switch" that can "turn off" some cellular processes that are protective against aging and metabolic diseases. While more research is needed, the findings may open doors for new drug treatments to halt or slow development of metabolic diseases like type 2 diabetes or heart disease. The research findings appear in the December 1, 2010 issue of Cell Metabolism.

Mitochondrial dysfunction observed in children with full syndrome autism

Preliminary research has found that children with autism are more likely to have impaired mitochondrial function (structures within cells responsible for energy production) and mitochondrial DNA abnormalities than typically developing children, according to a study in the December 1 issue of JAMA.

Scientists create couch potato mouse model to study muscle function

Daniel Kelly, M.D., and his colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) at Lake Nona have unveiled a surprising new model for studying muscle function: the couch potato mouse.

Stealth Peptides introduces Bendavia clinical candidate at AHA Scientific Sessions

Stealth Peptides, a privately held biopharmaceutical company developing innovative mitochondrial therapies for diseases with significant unmet medical needs, introduced its lead clinical candidate, Bendavia, a novel compound that targets the mitochondrion, at the 2010 American Heart Association's (AHA) Scientific Sessions, Resuscitation Science Symposium.

Exhausted neurons die prematurely and trigger disease symptoms

We all know that living a stressful lifestyle can take its toll, making us age faster and making us more susceptible to the cold going around the office.

New findings could help scientists devise optimal therapies for Friedreich's ataxia

Scripps Research Institute scientists have taken a step closer to understanding the cause of Friedreich's ataxia, a debilitating neurological condition that affects tens of thousands of people worldwide, and so far has no cure.

New findings on mitochondrial haplogroups associated with successful aging to be presented at ASHG Meeting

Thousands of the world's top scientists and clinicians in the human genetics field will convene to present their latest research findings at the American Society of Human Genetics (ASHG) 60th Annual Meeting, on November 2-6, 2010, in Washington, D.C.

Lactic acid levels in brain linked to aging process

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the CNS.
