Discovery: VPS4A enzyme plays a key role in release of HIV particles

Human Immunodeficiency Virus - which causes AIDS - invades human immune cells and causes them to produce new copies of the virus, which can then infect new cells.

TREK1 activity offers a key target for fluoxetine and other antidepressant drugs

Using a unique and relatively simple cell-based fluorescent assay they developed, scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley have identified a means by which fluoxetine, the active ingredient in Prozac, suppresses the activity of the TREK1 potassium channel.

Study: Fluorescent probe may serve as useful tool in future surgeries to repair injured nerves

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered.

Immune protein exacerbates skin cancer due to sun exposure: Study

An unexpected immune protein exacerbates cancer due to sun exposure, report researchers in the January 27th issue of Nature. The study suggests that drugs blocking the protein might halt tumor growth in skin cancer patients.

Vasopressin in the brain maintains size of vasopressin neurons even when body fluid becomes more diluted

The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis.

Population of highly active neurons could provide insight into neocortex

Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks.

Odyssey Thera granted U.S. Patent for high-throughput screening of proteins

Odyssey Thera, Inc. announced today that the United States Patent and Trademark Office granted U.S. Patent No. 7,855,167. The invention describes technologies and high-throughput methods for identifying bimolecular interactions in vivo based on protein-fragment complementation assays.

Researchers discover new way to prevent spread of cancer

Scientists now know that some cancer cells spread, or metastasize, throughout the body the old-fashioned way -- by using their feet. But researchers at Duke Cancer Institute have discovered a way to short-circuit their travels by preventing the development of these feet, called invadopodia. This discovery is even more important because preventing the development of these "feet" also eliminates the action of proteins present in the feet that burn through intact tissue and let cancer cells enter new cells.

Cellectis bioresearch licenses fluorescent proteins from Evrogen

Cellectis bioresearch, the specialist in genome customization and subsidiary of Cellectis, today announced that it has signed a non-exclusive agreement with Evrogen (Moscow, Russia) for access to its fluorescent proteins. This license allows Cellectis bioresearch to incorporate these proteins into its own products and will expand the company's offering of genome engineering tools.

New cell-based assay for reliable testing of HIV inhibitors

EASY-HIT is a new cell-based assay system for simple and reliable testing of HIV inhibitors. This system was developed under the leadership of Professor Ruth Brack-Werner at the Institute of Virology.

State-of-the-art imaging system helps locate and count myriad connections between brain nerve cells

Researchers at the Stanford University School of Medicine, applying a state-of-the-art imaging system to brain-tissue samples from mice, have been able to quickly and accurately locate and count the myriad connections between nerve cells in unprecedented detail, as well as to capture and catalog those connections' surprising variety.

New stem cell-infused patch improves heart function after myocardial infarction

University of Cincinnati (UC) researchers have found that applying a stem cell-infused patch together with overexpression of a specific cell instruction molecule promoted cell migration to damaged cardiac tissue following heart attack and resulted in improved function in animal models.

Researchers improvise fruit fly as a model system to study brain development, disorders

VIB researchers attached to the K.U.Leuven have improved the fruit fly as a model for studying the connections between brain cells. The researchers developed a specific marker for a part of the fly's nerve cell which had previously been difficult to distinguish. Their discovery will not only contribute to gaining a better insight into brain development but also makes the fruit fly into a better model system for studying brain development and brain disorders.

Menopausal estrogen replacement therapy speeds growth of ovarian cancer

Estrogen therapy used by menopausal women causes a type of ovarian cancer to grow five times faster, according to a new study by researchers at the University of Colorado Cancer Center.

First in vivo screening system for complete human nuclear hormone receptor family

The InDanio screening system can be used, for example, to functionally characterize 'orphan' receptors - those for which their natural ligands or specific function are unknown - and thus qualify them as potential targets for drug discovery. The system can also be used to screen compound libraries in order to identify and refine potential new drugs that target NR proteins.

Takeda, Envoy enter three-year research alliance to develop schizophrenia drug

Takeda Pharmaceutical Company Limited, a global pharmaceutical company, and Envoy Therapeutics Inc., a recently formed drug discovery company, today announced that they have formed a three-year research alliance aimed at discovering drugs for schizophrenia that will have greater efficacy and safety compared to current therapies.

UIC develops new technique to anchor teeth back in jaw using stem cells

A new approach to anchor teeth back in the jaw using stem cells has been developed and successfully tested in the laboratory for the first time by researchers at the University of Illinois at Chicago.

Neurons that control sexual behavior mapped

How the bundles of neurons in the brain controls behaviour remains an ongoing mystery. Researchers from the Institute of Molecular Pathology (IMP), in Vienna, Austria, and the Laboratory of Molecular Biology (LMB/MRC), Cambridge, United Kingdom, have mapped neurons of the fruit fly, Drosophila, that controls sexual behavior. "We literally untangled the mess of wires in the fly brain and laid the ground plans for investigating a complex behavior in a simple organism," says Jai Yu, whose doctoral work is published in Current Biology.

Research on adult mammary stem cells may help to cure breast cancer

For the first time, researchers at Fred Hutchinson Cancer Research Center have identified and isolated adult mammary stem cells in mice. Long-term implications of this research may include the use of such cells to regenerate breast tissue, provide a better understanding of the role of adult stem cells in breast cancer development, and develop potential new targets for anti-cancer drugs.

New TRIM5α-based treatments can knock out HIV in humans: Research

Using a $225,000 microscope, researchers have identified the key components of a protein called TRIM5α that destroys HIV in rhesus monkeys.The finding could lead to new TRIM5α-based treatments that would knock out HIV in humans, said senior researcher Edward M. Campbell, PhD, of Loyola University Health System.
