Ubiquitin protein may treat variety of diseases from Parkinson's to diabetes

A tiny protein called ubiquitin - so named because it is present in every cell of living things as dissimilar as hollyhocks and humans - may hold the key to treatment for a variety of diseases from Parkinson's to diabetes.

Researchers say hCNT1 protein may affect cancer cells physiology, apart from transport function

The protein hCNT1, which plays a major role in nucleoside transport, may have other biological functions that may affect cancer cells physiology, apart from their transport function. This is the main conclusion of the new scientific work published on the journal Cell Death and Disease.

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.

GSA selects five early career researchers as recipients of fall 2013 DeLill Nasser Award

The Genetics Society of America is pleased to announce the selection of five early career researchers - one graduate student and four postdoctoral researchers - as recipients of a fall 2013 DeLill Nasser Award for Professional Development in Genetics.

Researchers discover potential target for cancer-fighting drugs

As tumors grow, their centers are squeezed of oxygen. And so tumors must flip specific genetic switches to survive in these hypoxic environments.

Human Argonautes directly cuts messenger RNA

Human Argonautes (hAgo), are key proteins involved in a process known as RNA interference. RNAi, as it is often called, is a mechanism that cells use to regulate gene expression.

Scientists discover new function of an enzyme that disposes of superfluous proteins

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbr-ck Center for Molecular Medicine Berlin-Buch as well as Professor Michael Glickman and Professor Aaron Ciechanover of Technion, the Technical University of Israel in Haifa, have now discovered a new function of an enzyme that is involved in this vital process.

$2 million grant to provide instrumentation, core facilities devoted to synthetic biology

The Roy J. Carver Charitable Trust has awarded a $2 million grant to the Institute for Genomic Biology at the University of Illinois at Urbana-Champaign. Under the leadership of Principal Investigator Dr. Huimin Zhao and co-Principal Investigator Dr. Christopher Rao, the grant will be disbursed over two years to provide instrumentation and core facilities for a new research theme devoted to the new scientific subdiscipline of synthetic biology.

Researchers create complete visual map of telomerase enzyme

Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.

Protein with key job in muscle function moonlights in nucleus to help regulate genes

A key building block of life, actin is one of the most abundant and highly conserved proteins in eukaryotic cells.

UMDNJ biochemist to research into mechanisms that control gene expression in mitochondria

Dmitry Temiakov, PhD, a biochemist at the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine, has received a five-year, $1.5 million grant from the National Institutes of Health (NIH) to fund research into the molecular mechanisms that control gene expression in mitochondria, the organelles that are the "power plants" of cellular activity.

UPC develops new system for electroporation of cell cultures

Researchers from the Polytechnic University of Catalonia have developed a technique that improves and cuts the cost of a technique called electroporation, which involves opening pores in cell membranes using an electric field to introduce substances like drugs and DNA. Current methods are aggressive and expensive whereas the new system manages to apply low voltage electroporation with a small printed circuit board, which costs less than a Euro per unit and does not damage cells.

Simple and inexpensive method to cut DNA could transform genetic medicine

A simple, precise and inexpensive method for cutting DNA to insert genes into human cells could transform genetic medicine, making routine what now are expensive, complicated and rare procedures for replacing defective genes in order to fix genetic disease or even cure AIDS.

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.

Scientists sequence complete genome of leeches

Leeches, despite the yuck factor, have captured the hearts of two University of California, Berkeley, scientists who are part of a team that this week is publishing the leech's complete genome sequence.

CNIO creates 2 new databases to study the human genome

Scientists from the Structural Computational Biology Group at the Spanish National Cancer Research Centre (CNIO), led by Alfonso Valencia, together with French and American researchers, have published recently two articles in the journal Nucleic Acid Research (NAR) that introduce two new databases for studying the human genome.

Research team identifies turbo switch in the vital calcium pump in our body's cells

A Danish-British research team has discovered a turbo switch in the vital calcium pump in our body's cells. In studies at the X-ray source DORIS at Deutsches Elektronen-Synchrotorn DESY in Hamburg and the European Synchrotron Radiation Facility ESRF in Grenoble the team discovered that the on-off switch of the pump has a previously unknown third position, which switches the pump into a turbo gear.

Researchers obtain first detailed and complete picture of PRC2 protein

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).

UCP2 uncoupling protein occurs mainly in cells of the immune system

When uncoupling proteins are active, mitochondria produce heat instead of ATP. This may be useful under certain circumstances, such as when an animal is hibernating. But non-hibernating animals also have them. Particularly poorly understood is the uncoupling protein UCP2. Elena Pohl and colleagues at the University of Veterinary Medicine, Vienna, show that the protein occurs mainly in cells of the immune system.
