Scientists develop new method to directly identify miRNA targets in cells

Human cells are thought to produce thousands of different microRNAs (miRNAs)-small pieces of genetic material that help determine which genes are turned on or off at a given time. miRNAs are an important part of normal cellular function, but they can also contribute to human disease-some are elevated in certain tumors, for example, where they promote cell survival.

Novel stem cell transplantation holds promise for HIV prevention

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

Study sheds light on cellular mechanisms involved in flu resistance

Scientists from the University of Utah School of Medicine have discovered that a mouse protein called IFITM3 contributes to the body's defense against some types of viral infections by binding to an enzyme responsible for regulating the pH of a cell's waste disposal system.

Study provides new information on why A-T disease attacks the brain

Rutgers scientists think they have found a way to prevent and possibly reverse the most debilitating symptoms of a rare, progressive childhood degenerative disease that leaves children with slurred speech, unable to walk, and in a wheelchair before they reach adolescence.

Aurora-A protein blocks proper functioning of tumor-suppressor p73

A protein abundantly found in treatment-resistant cancers holds an important tumor-suppressor out of the cell nucleus, where it would normally detect DNA damage and force defective cells to kill themselves, a team of scientists reports in the current Cancer Cell.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Scientists discover extremely long-lived proteins in aging rats

One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.

Study finds protein's entwined arm movements may control fate of potentially toxic payload

Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else.

Methylation also plays a significant role outside the nucleus

The same mechanism that stabilises the DNA in the cell nucleus is also important for the structure and function of vertebrate muscle cells. This has been established by RUB-researchers led by Prof. Dr. Wolfgang Linke (Institute of Physiology) in cooperation with American and German colleagues.

New imaging technology may pinpoint subtle aberrations in molecular biosignature of cancer

Despite advances in both the diagnosis and treatment of breast cancer, the disease remains a leading worldwide health concern.

Cardiff University technique could help predict IVF embryos with best success chances

A new technique successfully used in mice to identify embryos likely to result in a successful pregnancy could be used in humans, potentially boosting IVF success rates and helping to reduce the number of multiple births, according to Cardiff University scientists.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

Access partners to exploit CobaCyte and CobOral technology for targeted RNAi therapeutic delivery

ACCESS PHARMACEUTICALS, INC., a biopharmaceutical company leveraging its proprietary drug-delivery platforms to develop treatments in areas of oncology, cancer supportive care and diabetes, announced it has entered into an agreement with a major player in RNAi industry to exploit its CobaCyte and CobOral technology for the targeted delivery of RNAi therapeutics.

Researchers show how nuclear receptors battle each other during fruit fly metamorphosis

Growing up just got more complicated. Thomas Jefferson University biochemistry researchers have shown for the first time that the receptor for a major insect molting hormone doesn't activate and repress genes as once thought. In fact, it only activates genes, and it is out-competed by a heme-binding receptor to repress the same genes during the larval to pupal transition in the fruit fly.

Protein that allows Ebola virus to attack cells discovered

A U.S. research team has discovered a protein called Niemann-Pick C1 (NPC1), which they found was responsible for allowing Ebola virus to enter and replicate within cells.

Researchers discover NPC1 protein as crucial for Ebola virus to enter host cells

Although outbreaks are rare, Ebola virus, the cause of Ebola hemorrhagic fever (EHF), is one of the deadliest known viruses affecting humans. According to the World Health Organization (WHO), approximately 1,850 EHF cases with more than 1,200 deaths have been documented since the virus was identified in 1976.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

New protein discovery could help develop intracellular biologic drugs

Permeon Biologics, a biopharmaceutical company pioneering a novel class of intracellular protein biologics, today announced the discovery of an entirely new class of naturally occurring human supercharged proteins called Intraphilins-.
