New kind of on-off switch for cortisol release in the brain discovered

After we sense a threat, our brain center responsible for responding goes into gear, setting off a chain of biochemical reactions leading to the release of cortisol from the adrenal glands.

NK cells play an important role in rejection of porcine chondrocytes transplantation

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have studied for the first time the response of human NK cells (Natural Killer) against porcine chondrocytes (cartilage cells).

Researchers discover how mTOR protein leads to cancer metastasis

Uncovering the network of genes regulated by a crucial molecule involved in cancer called mTOR, which controls protein production inside cells, researchers at the University of California, San Francisco (UCSF) have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer.

Study examines abdomyosarcoma growth in mouse models of muscular dystrophy

Inflammation, cell division and cell differentiation that occur during skeletal muscle regeneration may provide an ideal environment for the highly malignant tumor, rhabdomyosarcoma to arise. These are the findings from a Nationwide Children's Hospital study that examined rhabdomyosarcoma growth in mouse models of muscular dystrophy.

Insight into relationship between two types of suppressors in cancerous tumors

The University of Kentucky has announced that Dr. Daret St. Clair, the James Graham Brown Endowed Chair and professor of toxicology, has published the first comprehensive study that provides insight into the relationship between two types of suppressors in cancerous tumors. The results will enhance the understanding of transcriptional mechanisms in carcinogenesis.

Targeting versican protein may help stop breast cancer metastasis

Oncologists have known that in order for cancer cells to spread, they must transform themselves so they can detach from a tumor and spread to a distant organ. Now, scientists at Weill Cornell Medical College have revealed critical steps in what happens next -- how these cells reverse the process, morphing back into classical cancer that can now grow into a new tumor.

Allergan's cell-based assay for botulinum toxin type A products receives positive opinions

Allergan is pleased to announce the company has received two positive opinions regarding its fully in vitro, cell-based assay for use in the stability and potency testing of BOTOX and VISTABEL (Allergan's botulinum toxin type A products).

Study reveals how mutation shuts down DJ-1 protein's neuroprotective abilities

Purdue University researchers revealed how a mutation in a protein shuts down a protective function needed to prevent the death of neurons in Parkinson's disease, possibly opening the door to new drug strategies to treat the disorder.

Researchers discover mechanism of thermostat protein

Johns Hopkins and National Taiwan University researchers have discovered more details about how an energy sensing "thermostat" protein determines whether cells will store or use their energy reserves.

Link between brain dominance and laterality of cell phone use

If you're a left brain thinker, chances are you use your right hand to hold your cell phone up to your right ear, according to a new study from Henry Ford Hospital in Detroit.

VTT participates in two new EU projects that focus on type 2 diabetes

VTT is participating in two new European projects focusing on type 2 diabetes. The projects aim at identifying new therapeutic choices and strategies for preventing the disease. Focus is on obtaining information on cellular dysfunction in diabetes and the effects of changes in lifestyle. The goal includes planning individual lifestyle instructions for people at high risk of diabetes and exploiting the results in a major European health insurance system.

OGF-OGFr axis discovery provides new insights into ovarian cancer

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the presence and integrity of the opioid growth factor receptor (OGFr), which mediates the inhibitory action of opioid growth factor (OGF) on cell proliferation, is a key to understanding the progression and treatment of human ovarian cancer.

New chemical compound to treat brain damage from stroke

Researchers at the University of Copenhagen have designed, produced and patented a new chemical compound for the possible treatment of brain damage caused by stroke. The compound binds 1,000 times more effectively to the target protein in the brain than the potential drug currently being tested on stroke victims.

Mitochondria may be promising new target for cancer treatment

Mitochondria, tiny structures within each cell that regulate metabolism and energy use, may be a promising new target for cancer therapy, according to a new study. Manipulation of two biochemical signals that regulate the numbers of mitochondria in cells could shrink human lung cancers transplanted into mice, a team of Chicago researchers report in the journal FASEB.

Insulin production may persist for decades after onset of type 1 diabetes

Massachusetts General Hospital (MGH) research has found that insulin production may persist for decades after the onset of type 1 diabetes. Beta cell functioning also appears to be preserved in some patients years after apparent loss of pancreatic function. The study results appear in the March issue of Diabetes Care.

DANSR/FORTE assay more effective in diagnosing Edwards and Down syndrome

Using a noninvasive test on maternal blood that deploys a novel biochemical assay and a new algorithm for analysis, scientists can detect, with a high degree of accuracy, the risk that a fetus has the chromosomal abnormalities that cause Down syndrome and a genetic disorder known as Edwards syndrome.

Electronic properties of DNA can play a role in early diagnosis of cancer-causing mutations

Scientists have discovered that cancer-causing genetic mutations have better-disguised electronic signatures than other mutations - a trait which could help them fly under the radar of the body's defence mechanisms.

Key regulator of lens development also controls mechanosensory neuron development

A gene known to control lens development in mice and humans is also crucial for the development of neurons responsible for mechanosensory function, as neurobiologists of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have now discovered.
