Focused Treatment For Childhood Cancer

...that increased activity of Sonic Hedgehog (SHH), a signaling molecule crucial to brain development, is linked t...oped compounds that can block the uncontrolled SHH signaling found in the tumors could potentially be used as a therapy in children with medulloblastoma. Researc...

Scientists locate key hormone involved in appetite control

...relin is believed to be part of the body's natural signaling system which informs the brain when it's time to eat. In both mice and humans, ghrelin levels increase naturally in response to weight loss or reduced caloric intake and the hormone diminishes in response to food intake. The scientists used a method...

Brain Enzyme Found To Regulate Weight

...leptin because its works more directly on appetite signaling at the end of the biochemical pathway in the brain. However researchers say clinical trials on human patients will take years to complete....

New Hair in 15 Days Could Now Be A Possibility Say Researchers

...owth. Previous work has implicated Wnt/?-catenin signaling in embryonic hair follicle development, postnatal ...e researchers could transiently activate ?-catenin signaling at will. To test the effect of ?-catenin signaling on adult hair growth, the researchers shaved th...

New Drug Effective for Low Blood Pressure

...of the autonomic ganglion, which has minimal nerve signaling traffic when lying down. When standing up, however, nerve signaling traffic in the autonomic ganglion increases. Researchers theorized a drug that affects the autonomic...

Another Cause of Thyroid Cancer Discovered

...nvolved. The fusion of these genes results in BRAF signaling normal cells to transform into malignant cells. This is a new discovery of cause for patients with thyroid tumors. Researchers conclude saying the discovery of the chromosomal rearrangement is remarkable and they add that their findings represent a ...

The Link Between Weight Loss and Heart Failure

...methods, they showed angiotensin II inhibits IGF-1 signaling in skeletal muscle, which in turn, leads to skeletal muscle loss. They also found a complete reversal of angiotensin-related weight loss in mice that were genetically engineered to produce more than the normal amount of IGF-1. Thus researchers belie...

Ruboxistaurin (RBX) may prevent vision loss in diabetic patients

...etic complications of the eye. a- PKC is the major signaling pathway which is stimulated by high blood glucose levels. In animal studies it was found that the abnormal activation of a-PKC decreases the blood flow to the retina. The research team has found oral administration of 32 milligrams/day of Ruboxista...

Proteinomics Research holds Key to Stomach Cancer

... time a connection between stomach cancer and this signaling pathway has been made.” It is found that these basic research findings demonstrates that by lowering the Stat3 hyperactivity, we can suppress stomach cancer formation, importantly without affecting Stat3’s other important roles in the body. Add to ...

Toll-like Receptor (Tlr3) Attachment Leads To Lethal Encephalitis

...ovided by results suggesting that TNF-a receptor I signaling downstream of Tlr3 promotes WNV entry into the brain. Sporadic outbreaks of WNV infection of humans have become increasingly common over the past 5 years, particularly in North America and Europe. This new work identifying Tlr3 as the receptor allowi...

New Insight Gained For Allergic Reactions

...ely prompted the production of inflammatory immune signaling molecules and accumulation of inflammatory cells, a downstream event common to lung and other type of allergic inflammations. By contrast, ragweed pollen extract from which NADPH oxidase had been removed produced no reactive oxygen species, and resul...

Turmeric Found To Slow Down Melanoma Growth

...tosis, IKK. However, it did not suppress two other signaling pathways associated with melanomas and tumor proliferation, B-Raf/MEK/ERK and Akt pathways. Based on the studies, we conclude the curcumin is a potent suppressor of cell viability and inducer of apoptosis in melanoma cell lines and future investigat...

And now its super mice for longer memory

... created with a gene that blocks the function of a signaling protein called calcineurin in the brain. Calcineurin is thought to be a natural constraint on long-term memory. It speeds up the rate at which electrical signals in the brain die away, so that the messages they carry are not stored for long periods. ...

Good News For Those Of You Suffering From Rheumatoid Arthritis

... a protein called tumor necrosis factor (TNF) from signaling the release of joint-damaging substances. Adalimumab is approved for the treatment of moderate to severe rheumatoid arthritis in adults who do not respond to other treatments. Addressing future research priorities, long-term efficacy and safety stu...

New Study Offers Hope For Balding Men

...ir re-growth is by controlling the timing of a key signaling pathway. Bald mice that were genetically engineered to produce the Hairless protein were able to re-grow a thick fur. Lacking Hairless is a rare genetic disorder and is not the only reason why a person becomes bald. But the findings could help ...

PET scans may help deciding surgery for epilepsy

...t PET imaging with a marker that shows deficits in signaling for the neurotransmitter serotonin is more sensitive than the traditional PET measurement of brain glucose. When drugs fail to control epilepsy, brain surgery is often the only remaining therapeutic option. However, identifying the correct spot for...

Synthetic protein found to relieve arthritis symptoms in animal model

...ll surface receptor and prevents a needed chemical signaling pathway from functioning correctly. In ALPS, the signal pathway interrupted by PLAD leads to disease symptoms. But, the scientists reasoned, PLAD might also be able to block a related cell surface receptor one involved in passing signals, leading to ...

Novel protein found to enhance effect of Vitamin E and suppress prostate cancer
