Absence of Shp-2 enzyme near cartilage cells can lead to multiple benign cartilage tumors in mice

Rhode Island Hospital researchers have found that the absence of the Shp-2 enzyme near specialized cartilage cells can lead to the development of multiple benign cartilage tumors in mice, a model that recapitulates the rare human tumor syndrome metachondromatosis.

Scientists take important step toward pharmacologic development of treatment for fatal brain disorders

A team of researchers from Case Western Reserve University School of Medicine have identified a mechanism that can prevent the normal prion protein from changing its molecular shape into the abnormal form responsible for neurodegenerative diseases. This finding, published in the July 18 issue of Cell Reports, offers new hope in the battle against a foe that until now has always proved fatal.

Soy peptide injection dramatically reduces colon cancer metastasis in mice

After a recent University of Illinois study showed that injection of the soy peptide lunasin dramatically reduced colon cancer metastasis in mice, the researchers were eager to see how making lunasin part of the animals' daily diet would affect the spread of the disease.

Probiodrug to present studies on PQ912 for treatment of Alzheimer's disease at AAIC meeting

Probiodrug AG (Probiodrug) announced that it will be making two poster and two oral presentations at the upcoming Alzheimer's Association International Conference in Boston, MA July 13 - 18, 2013.

Tiny RNA molecules work as powerful regulators of immune response in mammals

A team led by scientists at The Scripps Research Institute (TSRI) has identified a family of tiny RNA molecules that work as powerful regulators of the immune response in mammals. Mice who lack these RNA molecules lose their normal infection-fighting ability, whereas mice that overproduce them develop a fatal autoimmune syndrome.

New approaches to regenerate insulin-producing cells for type I diabetes

They have also shown that any pancreatic β cells can be regenerated several times and that chemically-induced diabetes in mice can thus be "treated" repeatedly. The challenge for the researchers is now to show that these procedures can be applied to humans.

Caspase-2 protein contributes to cognitive decline associated with Alzheimer's disease

Researchers at Columbia University Medical Center have demonstrated that a protein called caspase-2 is a key regulator of a signaling pathway that leads to cognitive decline in Alzheimer's disease.

Chemical hormone released due to stress can trigger mechanism for late onset of Alzheimer's disease

A chemical hormone released in the body as a reaction to stress could be a key trigger of the mechanism for the late onset of Alzheimer's disease, according to a study by researchers at Temple University.

Diapocynin antioxidant protects neurobehavioral function in mice with Parkinson's disease

Diapocynin, a synthetic molecule derived from a naturally occurring compound (apocynin), has been found to protect neurobehavioral function in mice with Parkinson's Disease symptoms by preventing deficits in motor coordination.

Mannitol could prevent aggregation of toxic proteins in the brain, says Tel Aviv University researcher

Mannitol, a sugar alcohol produced by fungi, bacteria, and algae, is a common component of sugar-free gum and candy. The sweetener is also used in the medical field - it's approved by the FDA as a diuretic to flush out excess fluids and used during surgery as a substance that opens the blood/brain barrier to ease the passage of other drugs.

Scientists develop new tool for analyzing and characterizing aspects of the brain's neural circuitry

Scientists at the University of Massachusetts Medical School have developed a novel transgenic system which allows them to remotely activate individual brain cells in the model organism Drosophila using ambient temperature.

HEXIM1 gene makes heart healthier, suppresses breast cancer metastasis

Researchers at Case Western Reserve University have found that a single gene poses a double threat to disease: Not only does it inhibit the growth and spread of breast tumors, but it also makes hearts healthier.

Scientists find that mice develop age-related progressive motor symptoms of Parkinson's disease

The presence of Lewy bodies in nerve cells, formed by intracellular deposits of the protein α-synuclein, is a characteristic pathologic feature of Parkinson's Disease (PD). In the quest for an animal model of PD that mimics motor and non-motor symptoms of human PD, scientists have developed strains of mice that overexpress α-synuclein.

Findings have implications for potential gene therapies for autism spectrum disorders

A gene linked to autism spectrum disorders that was manipulated in two lines of transgenic mice produced mature adults with irreversible deficits affecting either learning or social interaction.

People with narcolepsy have increased number of neurons that produce histamine

A new study provides surprising evidence that people with narcolepsy have an increased number of neurons that produce histamine, suggesting that histamine signaling may be a novel therapeutic target for this potentially disabling sleep disorder.

Findings could lead to better understanding of learning and memory

Students preparing for final exams might want to wait before pulling an all-night cram session - at least as far as their neurons are concerned. Carnegie Mellon University neuroscientists have discovered a new intermediate phase in neuronal development during which repeated exposure to a stimulus shrinks synapses.

Potential new treatment approaches for liver diseases

By discovering the new mechanism by which estrogen suppresses lipid synthesis in the liver, UC Irvine endocrinologists have revealed a potential new approach toward treating certain liver diseases.

RIKEN researchers visualize memory formation for first time in zebrafish

In our interaction with our environment we constantly refer to past experiences stored as memories to guide behavioral decisions. But how memories are formed, stored and then retrieved to assist decision-making remains a mystery.

Kinase inhibitors: an interview with Jan Hoflack, CSO of Oncodesign

Kinase inhibitors are molecules that block the activity of kinases. Kinases are a specific class of enzymes. They are extremely important in signal transduction processes in the human body meaning that they actually regulate most of the physiological processes that take place in the body.

Scientists create animal models by altering specific genes associated with a given disease

Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.
