Pancreatic cancer cells know a way to sidestep chemotherapy, reveal Fox Chase researchers

Pancreatic cancer is one of the deadliest forms of the disease. The American Cancer Society's most recent estimates for 2014 show that over 46,000 people will be diagnosed with pancreatic cancer and more than 39,000 will die from it. Now, research led by Timothy J. Yen, PhD, Professor at Fox Chase Cancer Center, reveals that one reason this deadly form of cancer can be so challenging to treat is because its cells have found a way to sidestep chemotherapy.

Penn scientists explore potential therapeutic target for cerebral cavernous malformations

Tens of millions of people around the world have abnormal, leak-prone sproutings of blood vessels in the brain called cerebral cavernous malformations (CCMs). These abnormal growths can lead to seizures, strokes, hemorrhages, and other serious conditions, yet their precise molecular cause has never been determined.

Study leads to discovery of rare genetic disorder

Recently, a grassroots effort initiated by families and clinicians led to the discovery of a human genetic disorder with severe consequences that is linked to a mutation in the human NGLY1 gene. In a big step towards understanding the effects of this mutation, research by scientists at the RIKEN-Max Planck Joint Research Center in Japan implicates the enzyme ENGase as the factor responsible for deficient protein degradation that occurs in the absence of mouse Ngly1 gene expression.

TSRI researchers identify enzyme that produces inflammatory lipid molecules in the brain

A team led by scientists at The Scripps Research Institute has identified an enzyme that produces a class of inflammatory lipid molecules in the brain. Abnormally high levels of these molecules appear to cause a rare inherited neurodegenerative disorder, and that disorder now may be treatable if researchers can develop suitable drug candidates that inhibit this enzyme.

Researchers identify a single protein as root cause of multiple allergic reactions

Johns Hopkins and University of Alberta researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, they say, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV

TSRI scientists identify 'mechanoreceptor' protein that mediates sense of touch in mammals

A team led by biologists at The Scripps Research Institute has solved a long-standing mystery in neuroscience by identifying the "mechanoreceptor" protein that mediates the sense of touch in mammals.

New single-cell genetic profiling techniques help uncover variation in pluripotent stem cells

Stem cells offer great potential in biomedical engineering due to their pluripotency, which is the ability to multiply indefinitely and also to differentiate and develop into any kind of the hundreds of different cells and bodily tissues. But the precise complexity of how stem cell development is regulated throughout states of cellular change has been difficult to pinpoint until now.

Fenofibrate benefits in diabetic retinopathy mediated through PPARα

Peroxisome proliferator–activated receptor α exerts protective effects on retinal pericytes, shows research that explains why fenofibrate is protective against diabetic retinopathy.

MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

TSRI study points way to potential therapies for hereditary spastic paraplegia

Scientists at The Scripps Research Institute have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The TSRI researchers found large droplets of triglycerides within the neurons of mice modeling the disease.

Studies explore role of STXBP5 gene in development of cardiovascular disease

Two independent groups of researchers led by Sidney (Wally) Whiteheart, PhD, of the University of Kentucky, and Charles Lowenstein, MD, of the University of Rochester, have published important studies exploring the role that a gene called STXBP5 plays in the development of cardiovascular disease.

New potential therapeutic targets for treatment of pulmonary arterial hypertension

Two new potential therapeutic targets for the treatment of pulmonary arterial hypertension, a deadly disease marked by high blood pressure in the lungs, have been identified by researchers at the University of Illinois at Chicago.

New evidence puts into doubt the long-held depression belief

New evidence puts into doubt the long-standing belief that a deficiency in serotonin - a chemical messenger in the brain - plays a central role in depression. In the journal ACS Chemical Neuroscience, scientists report that mice lacking the ability to make serotonin in their brains (and thus should have been "depressed" by conventional wisdom) did not show depression-like symptoms.

Researchers take major step forward in developing real ALS treatments

A series of studies begun by Harvard Stem Cell Institute scientists eight years ago has lead to a report published today that may be a major step forward in the quest to develop real treatments for amyotrophic lateral sclerosis, ALS, or Lou Gehrig's disease.

Mice lacking specific protein live longer lives with fewer age-related illnesses

While developing a new cancer drug, researchers at The Wistar Institute discovered that mice lacking a specific protein live longer lives with fewer age-related illnesses.

Loss of p62 protein in cells and tissue surrounding a tumor can influence tumor growth

A team of scientists from Sanford Burnham Medical Research Institute has found that the loss of a protein called p62 in the cells and tissue surrounding a tumor can enhance the growth and progression of tumors.

genOway to provide EUCOMM conditional knockout mouse models to study human diseases

genOway, the biotechnology company dedicated to the development of genetically modified animal models, the Wellcome Trust Sanger Institute (UK) and Helmholtz Zentrum München (Germany), members of the EUCOMM Program (European Conditional Mouse Mutagenesis Program) and its successor program EUCOMMTOOLS (EUCOMM: Tools for functional annotation of the mouse genome) announce today the signing of a license enabling genOway to provide industry scientists with conditional knockout (KO) models developed by EUCOMM.
