Novel strategy for characterizing RNAs transported from nerve cell to synapse

Despite decades of research, relatively little is known about the identity of RNA molecules that are transported as part of the molecular process underpinning learning and memory.

UCSB researchers examine role played by Rhs proteins in bacterial intercellular competition

There's an epic battle taking place that's not on the national radar: intercellular competition. While it's not an Olympic event, new research from UC Santa Barbara demonstrates that this microscopic rivalry can be just as fierce as humans going for the gold.

Metallothioneins play major role in virulence of Cryptococcus neoformans

Metallothioneins, proteins able to capture metal ions, play a major role in the virulence of Cryptococcus neoformans, a fungal pathogen which causes severe infections in immunodeficient and immunocompetent individuals (AIDS patients, transplant receivers, etc.)

Research provides better understanding of microbiological factors of periodontitis

Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition.

Insight into how protein synthesis and degradation help regulate delicate ballet of cell division

Biochemists at the University of Massachusetts Amherst including assistant professor Peter Chien recently gained new insight into how protein synthesis and degradation help to regulate the delicate ballet of cell division. In particular, they reveal how two proteins shelter each other in "mutually assured cleanup" to insure that division goes smoothly and safely.

tRNA synthetases play unexpected and critical role in cancer metastasis

Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected - and critical - additional role in cancer metastasis in a study conducted collaboratively in the labs of Karen Lounsbury, Ph.D., University of Vermont professor of pharmacology, and Christopher Francklyn, Ph.D., UVM professor of biochemistry.

MID1 complex binds with messenger RNA and controls synthesis of defective Huntingtin

Huntington's disease, also known as Huntington's chorea, is a hereditary brain disease causing movement disorders and dementia. In Germany, there are about 8,000 patients affected by Huntington's disease, with several hundred new cases arising every year. The disease usually manifests between the ages of 35 and 50.

Scientists identify enigmatic aggregates linked to neurodegenerative diseases

The proteins that have now been identified shouldn't actually exist. Nevertheless, they build the core of cellular aggregates whose identity has been enigmatic until now. These aggregates are typically associated with hereditary neurodegenerative diseases including variants of frontotemporal dementia (FTD), also known as frontotemporal lobar degeneration (FTLD), and amyotrophic lateral sclerosis (ALS). They are likely to be damaging and might be a target for therapy.

Study demonstrates new fragile genomic sites responsible for chromosomal alterations in tumors

Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease. In this context, chromosomes tend to lose or duplicate entire regions, although, the mechanisms that initiate these chromosomal abnormalities are not fully understood.

SINEUP allows scientists to target individual genes in cells to increase protein production

One of the most innovative biotechnologies of the last decade has recently been developed. SINEUP allows scientists, for the first time, to target individual genes in cells to knockup, or increase, the amount of protein they make. The technique will improve Protein manufacture, analyse the function of genes and engineer improved cell function.

MiR-182 deeply involved in memory formation within the amygdala brain structure

It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins in cells, may play a far more important role in memory formation than previously thought.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

Ractopamine can boost pork production, does not affect meat quality or taste

Animal scientists in Brazil have found that a small dose of the feed additive ractopamine can boost pork production without changing how pork looks or tastes.

Consuming protein blend after exercise can promote muscle protein synthesis

A new study published in The Journal of Nutrition demonstrates the benefits of consuming a protein blend for muscle protein synthesis after exercise. This study is a first-of-its-kind, conducted by researchers at the University of Texas Medical Branch, and utilizes the proteins from soy, whey and casein consumed after an acute bout of resistance exercise. These proteins have complementary amino acid profiles and different digestion rates (amino acid release profiles).

Lack of TDP-43 protein can lead to frontotemporal dementia/ALS

Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

Scientists evaluate two different strategies to treat Usher syndrome

After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the repair of mutated genes or the deactivation of the genetic defects using agents.

Crucial link between protein synthesis and autism spectrum disorders

Researchers from McGill University and the University of Montreal have identified a crucial link between protein synthesis and autism spectrum disorders (ASD), which can bolster new therapeutic avenues.

UPR pathway helps tumor cells escape apoptosis during development of lymphoma

A pathway called the "Unfolded Protein Response," or UPR, a cell's way of responding to unfolded and misfolded proteins, helps tumor cells escape programmed cell death during the development of lymphoma.

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."
