Protein blend intake following resistance exercise may build muscles

Today at Experimental Biology 2012, Dr. Blake Rasmussen and colleagues presented a new and first-of-its-kind clinical study: "Effect of Protein Blend vs. Whey Protein Ingestion on Muscle Protein Synthesis Following Resistance Exercise." The results of this study suggest that a protein blend (combination of soy, whey and casein) may be best to consume post-workout for building muscle. Specifically, the blend of proteins in this study showed an increase in a person's "anabolic window."

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Vaccination most promising against asthma

Asthma is a chronic inflammatory and respiratory disease caused by an abnormal reactivity to allergens in the environment. Of the several avenues of exploration that are currently being developed, vaccination appears to be the most promising approach.

UV light-activated on-off switch for Morpholinos

University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers.

Aberrations in translation regulators linked with hormone receptor-positive breast cancer survival

Four proteins involved in translation, the final step of general protein production, are associated with poor prognosis in hormone-receptor-positive breast cancer when they are dysregulated, researchers reported at the AACR Annual Meeting 2012.

Study explains how rapamycin also causes insulin resistance

A Penn- and MIT-led team explained how rapamycin, a drug that extends mouse lifespan, also causes insulin resistance. The researchers showed in an animal model that they could, in principle, separate the effects, which depend on inhibiting two protein complexes, mTORC1 and mTORC2, respectively.

Scientists uncover new layer of information in the genetic code

A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells - including the speed with which proteins are made.

Study reveals how Bdnf gene mutation contributes to severe obesity

Researchers at Georgetown University Medical Center have revealed how a mutation in a single gene is responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain. What results is obesity caused by a voracious appetite.

FoxO protein plays a significant role in regulation of skeletal muscle mass

If you want big muscles without working out, there's hope. In the March 2012 print issue of the FASEB Journal, scientists from the University of Florida report that a family of protein transcription factors, called "Forkhead (Fox0)" plays a significant role in the regulation of skeletal muscle mass.

Study examines mRNA transcripts in the sperm of fruitflies and humans

It had long been assumed that the human sperm cell's mission in life ended once it had transferred its freight of parental DNA to the egg. More recently however, other components of sperm have been implicated in fertilization, and perhaps even in subsequent embryonic development.

Researchers discover how mTOR protein leads to cancer metastasis

Uncovering the network of genes regulated by a crucial molecule involved in cancer called mTOR, which controls protein production inside cells, researchers at the University of California, San Francisco (UCSF) have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer.

Complex computer program helps analyze RNA structural motifs

Computer engineers may have just provided the medical community a new way of figuring out exactly how one of the three building blocks of life forms and functions.

Ability of the brain to rehearse is critical to make newly acquired memory more permanent

Edmonton-University of Alberta researchers have established that the ability of the brain to rehearse or repeat electrical impulses may be absolutely critical in order to make a newly acquired memory more permanent.

MSC-mediated RNAi transfer holds promise for Huntington's disease

A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington's disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death.

Hydrogen sulfide decreases manufacture of kidney scarring matrix proteins

Hydrogen sulfide, a gas notorious for its rotten-egg smell, may have redeeming qualities after all. It reduces high glucose-induced production of scarring proteins in kidney cells, researchers from The University of Texas Health Science Center San Antonio report in the Journal of Biological Chemistry.

KCC Director recognized for distinguished contributions to cancer care

Richard Pestell, M.D., Ph.D., FACP, Director of the Kimmel Cancer Center at Jefferson (KCC), has been named a 2011 Fellow of the American Association for the Advancement of Science.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Researchers reveal stress-induced machinery of protein synthesis involved in bacterial cell death

Researchers at the Hebrew University of Jerusalem and the University of Vienna have revealed for the first time a stress-induced machinery of protein synthesis that is involved in bringing about cell death in bacteria.

Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.
