UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

Study finds novel function of non-protein coding RNA

While studying Parkinson's disease, an international research group made a discovery which can improve industrial protein synthesis for therapeutic use. They managed to understand a novel function of non-protein coding RNA: the protein synthesis activity of coding genes can be enhanced by the activity of the non-coding one called "antisense."

Study sheds light on fundamental cellular process

Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes-and revealing new clues as to what happens when this process goes awry.

MiR-34a plays a key role in obesity

Scientists have identified a key molecular player in a chain of events in the body that can lead to fatty liver disease, Type II diabetes and other metabolic abnormalities associated with obesity. By blocking this molecule, the researchers were able to reverse some of the pathology it caused in obese mice.

UCSF-led research team targets physiological factors that lead to asthma attack

A new study that identifies ways to reduce the factors that lead to an asthma attack gives hope to asthma sufferers. A UCSF researcher and his colleagues believe they have found a way to help asthma sufferers by impeding the two most significant biological responses that lead to an asthma attack.

RNA researcher to receive 2012 Pearl Meister Greengard Prize from The Rockefeller University

Joan A. Steitz, Ph.D., a pioneer in the field of RNA biology whose discoveries involved patients with a variety of autoimmune diseases, will be awarded the 2012 Pearl Meister Greengard Prize from The Rockefeller University. The prize, which honors female scientists who have made extraordinary contributions to biomedical science and carries an honorarium of $100,000, will be presented at a ceremony on Thursday, November 29 at Rockefeller University's Caspary Auditorium.

Eliminating jnk3 enzyme leads to 90% reduction in Alzheimer's plaque-forming compounds

Scientists have found that eliminating an enzyme from mice with symptoms of Alzheimer's disease leads to a 90 percent reduction in the compounds responsible for formation of the plaques linked to Alzheimer's disease.

DEAD-box proteins function as recycling nanopistons when unwinding RNA

AUSTIN, Texas-Molecular biologists at The University of Texas at Austin have solved one of the mysteries of how double-stranded RNA is remodeled inside cells in both their normal and disease states. The discovery may have implications for treating cancer and viruses in humans.

Abnormalities in mitochondrial length promote development of neurodegenerative 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 development of neurodegenerative diseases such as Alzheimer's.

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Similar molecular pathways involved in intellectual disability due to Fragile X and Down syndromes

Intellectual disability due to Fragile X and Down syndromes involves similar molecular pathways report researchers in The EMBO Journal. The two disorders share disturbances in the molecular events that regulate the way nerve cells develop dendritic spines, the small extensions found on the surface of nerve cells that are crucial for communication in the brain.

Researchers identify six genes with driving mutations in melanoma

It's been a burning question in melanoma research: Tumor cells are full of ultraviolet (UV)-induced genetic damage caused by sunlight exposure, but which mutations drive this cancer? None have been conclusively tied to melanoma. The sheer abundance of these passenger mutations has obscured the search for genetic driver mutations that actually matter in melanoma development and progression.

Read-through molecule improves muscle function in DMD

A compound that results in a read-through on nonsense mutations in messenger RNA restores dystrophin expression in an animal model of Duchenne muscular dystrophy, research shows.

Exercise-related hormones do not play an influential role in building muscle

New research from scientists at McMaster University reveals exercise-related testosterone and growth hormone do not play an influential role in building muscle after weightlifting, despite conventional wisdom suggesting otherwise.

Hepatocytes can create new liver system in mouse models

Researchers in Japan have found that hepatocytes, cells comprising the main tissue of the liver and involved in protein synthesis and storage, can assist in tissue engineering and create a "new liver system" in mouse models when donor mouse liver hepatocytes are isolated and propagated for transplantation.

Aminoacyl-tRNA synthetases important targets for development of new drugs against major diseases

Researchers at the University of Gothenburg, Sweden, are working to develop substances that can prevent parasites, bacteria and fungi from producing essential proteins, research that could, in the long term, lead to new drugs for several major diseases.

PERK protein necessary to maintain behavioral flexibility

Researchers have identified a protein necessary to maintain behavioral flexibility, which allows us to modify our behaviors to adjust to circumstances that are similar, but not identical, to previous experiences. Their findings, which appear in the journal Cell Reports, may offer new insights into addressing autism and schizophrenia—afflictions marked by impaired behavioral flexibility.
