Key to treating neurodegenerative prion diseases may lie in ribosome, shows research

New research results from Uppsala University, Sweden, show that the key to treating neurodegenerative prion diseases such as mad cow disease and Creutzfeldt-Jakob disease may lie in the ribosome, the protein synthesis machinery of the cell. The results were recently published in the Journal of Biological Chemistry.

Synthetic biology technology could lead to new antibiotics, modified protein-generators

Synthetic biology researchers at Northwestern University, working with partners at Harvard Medical School, have for the first time synthesized ribosomes -- cell structures responsible for generating all proteins and enzymes in our bodies -- from scratch in a test tube.

Berkeley Lab scientists create atomic-scale structure of ribosome

This may look like a tangle of squiggly lines, but you're actually looking at a molecular machine called a ribosome. Its job is to translate DNA sequences into proteins, the workhorse compounds that sustain you and all living things.

Researchers produce first genome-wide investigation of cap-independent translation

Because of their central importance to biology, proteins have been the focus of intense research, particularly the manner in which they are produced from genetically coded templates-a process commonly known as translation. While the general mechanism of translation has been understood for some time, protein synthesis can initiate by more than one mechanism. One of the least well understood mechanisms is known as cap-independent translation.

New study sheds light on DEAD-box proteins

Proteins, the workhorses of the body, can have more than one function, but they often need to be very specific in their action or they create cellular havoc, possibly leading to disease.

Researchers identify defective gene responsible for isolated congenital asplenia

The spleen is rarely noticed, until it is missing. In children born without this organ, that doesn't happen until they become sick with life-threatening bacterial infections.

Nine Nobel laureates to present their research at American Chemical Society meeting

At least nine Nobel laureates have research that will be presented here this week during the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.

SRSF1 protein can prevent cancerous proliferation by stabilizing p53

Some cellular proteins have multiple, and occasionally opposing, functions. Professor Adrian Krainer and colleagues at Cold Spring Harbor Laboratory demonstrate in a paper published online today in Molecular Cell that the oncogenic protein SRSF1 can also trigger a stop in cell growth and prevent cancerous proliferation by stabilizing p53, the powerful tumor-suppressor protein.

Researchers discover genetic defect that can halt cell growth

A Melbourne-based research team has discovered a genetic defect that can halt cell growth and force cells into a death-evading survival state.

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.

Researchers identify molecular mechanism that regulates autophagy

Researchers at the University of California, San Diego School of Medicine have identified a molecular mechanism regulating autophagy, a fundamental stress response used by cells to help ensure their survival in adverse conditions.

Scientists determine structure of Ltn1 protein

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells of all plants, fungi and animals.

Hepatitis C virus takes over invaded cell by hijacking protein making machinery

Researchers at the University of Colorado School of Medicine have figured out intimate details of how the hepatitis C virus takes over an invaded cell, a breakthrough that could point to way for new treatments for the virus.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

Research reveals surprisingly complex protein-coding capacity of human cytomegalovirus

New findings reveal the surprisingly complex protein-coding capacity of the human cytomegalovirus, or HCMV, and provide the first steps toward understanding how the virus manipulates human cells during infection. The genome of the HCMV was first sequenced over 20 years ago, but researchers have now investigated the proteome-the complete set of expressed proteins-of this common pathogen as well.

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."

NCI identifies method by which cancerous mRNA escapes the body's safeguards

In innumerable spy movies, the hero or a villain imprints a key in clay in order to later make an exact copy. In the body, the clay is messenger RNA, or mRNA, which imprints a gene and transfers the plans to a ribosome, where the mRNA's code is manufactured into a protein - the shady shop where the clay imprint becomes a key.

Researchers discover smallest and fastest-known RNA switches

A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.

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.

CYCLOPS genes may serve as targets for cancer therapies

The genomic tumult within tumor cells has provided scientists at Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard with clues to an entirely new class of genes that may serve as an Achilles' heel for many forms of cancer.
