Cannabinoid cell surface receptor plays a tumor-suppressing role in human colorectal cancer

CB1 is well-established for relieving pain and nausea, elevating mood and stimulating appetite by serving as a docking station for the cannabinoid group of signaling molecules. It now may serve as a new path for cancer prevention or treatment.

Chronic exposure to estrogen impairs some cognitive functions

University of Illinois researchers report this week that chronic exposure to estradiol, the main estrogen in the body, diminishes some cognitive functions. Rats exposed to a steady dose of estradiol were impaired on tasks involving working memory and response inhibition, the researchers found.

Variation in TNFAIP3 gene - cutting the brakes on the immune system

Your immune system may have more in common with a Corvette than you thought. When a virus or bacteria enters a human body, the immune system revs up to fight and expel the invader. Once the invader is gone, the body puts on the brakes to stop the immune response.

Researchers discover novel kind of learning gene

Scientists at the Freie Universität Berlin have come one step closer to unraveling the molecular basis of learning. A team led by neurobiologist Bjorn Brembs has discovered the first gene for operant conditioning in the fruit fly Drosophila.

Genetic defect in skin cells leads to neurodermatitis, hay fever and asthma

New knowledge points to the fact that a genetically induced lack of filaggrin, a key protein of the skin barrier, plays a decisive role in the origin of allergies.

Scientists develop ultra-sensitive optical protein sensor, a first for a salivary diagnostic test

For people who dislike needles, medical tests that require a drop of saliva instead of a vial of blood will one day make a trip to a doctor or dentist much easier. But as scientists now construct the first of these saliva tests for early signs of cancer and other diseases, they continue to push the technological envelope in interesting ways.

Inherited form of hearing loss stems from gene mutation

Pat Phalin learned she had hearing loss at 30, when she volunteered to give hearing tests at her local school. The pupils heard sounds she could not hear.

Scientists discover how a tiny protein senses all the communications in a cell

Cells rely on calcium as a universal means of communication. For example, a sudden rush of calcium can trigger nerve cells to convey thoughts in the brain or cause a heart cell to beat. A longstanding mystery has been how cells and molecules manage to appropriately sense and respond to the variety of calcium fluctuations within cells.

Mechanism for postpartum depression found in the brains of mice

Researchers have pinpointed a mechanism in the brains of mice that could explain why some human mothers become depressed following childbirth. The discovery could lead to improved treatment for postpartum depression.

An unsuspected weakness in tuberculosis - potential drug target

With antibiotic resistance on the rise, tuberculosis is emerging as a bigger global health threat than ever before.

New oral vaccine combats various versions of the plague

A University of Central Florida researcher may have found a defense against the Black Plague, a disease that wiped out a third of Europe's population in the Middle Ages and which government agencies perceive as a terrorist threat today.

Eroded telomeres are behind dyskeratosis congentia aging syndrome

Each time a cell divides, the protective caps at the ends of chromosomes shorten - and when these caps are gone, so are we. Now, by using an unconventional strategy to shorten telomeres in mice, researchers at Rockefeller University have not only created the first faithful mouse model for studying a rare yet fatal premature aging syndrome, but they have revealed the molecular defect behind the disease.

Rember, new Alzheimer's drug offers hope to sufferers

An experimental drug to treat Alzheimer's disease has had some promising results in early trials with patients.

Corn protein, zein being researched for drug delivery

The key to a better drug delivery method for cancer patients may be growing all across the Midwest, South Dakota State University research suggests.

ISU researchers find possible alternative adjuvant for alum to boost the effectiveness of vaccines

On the rocky road of cancer research, Indiana State University scientists have made important discoveries.

Estrogen treatments may sharpen mental performance in some women

Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs.

Sleep gene - search is on!

While scientists and physicians know what happens if you don't get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep.

Cell mechanism discovery may lead to new treatments for cystic fibrosis, other inherited diseases

Researchers in Japan and Canada have discovered a key component of the quality control mechanism that operates inside human cells - sometimes too well. The breakthrough has significant implications for the development of new treatments for cystic fibrosis (CF) and some other hereditary diseases, the researchers say. Their results were published July 25 in the journal Science.

Australian Alzheimer's trial published in the Lancet

Prana Biotechnology Limited announced today the publication of the results of its Phase 2a clinical trial on Alzheimer's disease patients in The Lancet Neurology journal.

Markers in blood and spinal fluid, and a new imaging agent, show promise for early detection of Alzheimer's

With the continued aging of the population and the growing epidemic of Alzheimer's, early detection of the disease is crucial for risk assessment, testing new therapies, and eventual early intervention with better drugs, once they are developed. Four studies reported today at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008) in Chicago bring us closer to that goal of early detection by describing advances in biomarkers.
