Lee Rannals for redOrbit.com — Your Universe Online Boosting the activity of a particular enzyme can help block tumors from growing, according to research published in Nature Chemical Biology. Cancer cells use up most of their energy by reproducing themselves, but in order to do this they must produce new cellular building blocks like DNA, carbohydrates and lipids. Biologists found that jacking up the activity of the enzyme pyruvate kinase can disrupt the production of tumors...

Researchers find that optimal length of mitochondria in neurons is essential to preventing onset of Alzheimer's and other tau-related diseases Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the...

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease. For more than 60 years,...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

The popular belief that "cancer originates due to DNA mutations” is wrong” according to Samil Ozavar, who is the President of GEMM Research Ltd. Malignant transformation actually takes place due to an excessive build up of ATP in the cell that force a premature and uncontrolled cell division. A structural damage to the mitochondrial membrane channels that regulate the ATP flow to the cytosol are responsible for the excessive energy build that may lead to the formation of a...

Tracked step for step ATP splitting in membrane protein dynamically measured for the first time RUB researchers report in the Journal of Biological Chemistry How a transport protein obtains its driving force from the energy storage molecule ATP, has been tracked dynamically by RUB researchers. Using time-resolved infrared spectroscopy, they measured the structural changes in the bacterial membrane protein MsbA and its interaction partner ATP. The researchers led by Prof. Dr. Eckhard...

Scientists from Queen Mary, University of London have discovered a mechanism that controls the way that organisms breathe or photosynthesize, potentially paving the way for improved biofuel production. Writing in the journal PNAS, Dr Lu-ning Lu and Professor Conrad Mullineaux from Queen Mary's School of Biological and Chemical Sciences report that by exposing cells to different light conditions, they have changed the way in which electrons are transported. Professor Mullineaux explains:...

Milk Ingredient Protects Against Obesity
2012-06-06 05:11:23

Connie K. Ho for redOrbit.com Milk ads have long proclaimed that milk does the body good. Now, there may be research that backs this idea of milk as having particular attributes to boost a healthy body. Researchers found that a natural ingredient in milk can help protect against obesity, even when mice consume foods that are high in fat. The findings, published in the June issue of Cell Metabolism, believe that the milk ingredient is similar to a new type of vitamin. The discovery of NR...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
