New treatment could stop progression of ALS

Researchers at Oregon State University announced today that they have essentially stopped the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, for nearly two years in one type of mouse model used to study the disease - allowing the mice to approach their normal lifespan.

Study could open door for new treatment targets to help Parkinson's disease patients walk more easily

Two secrets of one of the brain's most enigmatic regions have finally been revealed. In a pair of new studies, scientists from the Gladstone Institutes have discovered a specific neural circuit that controls walking, and they found that input to this circuit is disrupted in Parkinson's disease.

Scientists trace one of the causes of ischemia renal failure

Every year acute renal failure affects over 13 million people and leads to 1.7 million deaths across the globe. It often develops when an insufficient supply of oxygen reaches the kidneys, a condition called ischemia.

DNA imprinting defect may affect children diagnosed with osteosarcoma

Children diagnosed with osteosarcoma may be impacted by a DNA imprinting defect also found in parents, according to new research from the Masonic Cancer Center, University of Minnesota. DNA imprinting is a phenomenon in which just one of the two inherited genes is active while the other is present but inactive.

Synaptic plasticity alterations responsible for memory impairment in Alzheimer's disease

Neurons communicate with one another by synaptic connections, where information is exchanged from one neuron to its neighbor. These connections are not static, but are continuously modulated in response to the ongoing activity (or experience) of the neuron. This process, known as synaptic plasticity, is a fundamental mechanism for learning and memory in humans as in all animals.

E-cigarettes suppress immune defenses, alter inflammation and boost bacterial virulence

Researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System report data suggesting that e-cigarettes are toxic to human airway cells, suppress immune defenses and alter inflammation, while at the same time boosting bacterial virulence.

Blocking class II MHC molecules on graft endothelium limits acute rejection

A limitation of organ transplant is acute rejection of the graft by the host immune system. Graft rejection is mediated by the development of CD8+ cytotoxic T cells that target donor MHC class I molecules, and in animal models, these cells have been shown to develop in secondary lymphoid organs.

Combination of PARP inhibitors and c-MET may benefit breast cancer patients

Findings from a new study reveal that PARP inhibitors, an emerging class of drugs being studied in cancer clinical trials, may be enhanced by combining them with inhibitors targeting an oncogene known as c-MET which is overexpressed in many cancers.

UConn-led researchers identify specific gene linked to Hajdu-Cheney syndrome

Fragile bones are usually an old person's affliction, but sometimes children are born with them. Now, a team of researchers led by UConn professor Ernesto Canalis has shown in mice that a specific gene can cause the disease, called Hajdu-Cheney syndrome. Overabundant bone-absorbing cells may be causing the disorder's characteristic bone loss, and the researchers hope to find a potential treatment.

Novel drug shows promise against metastatic breast cancer in mouse models

A doctor treating a patient with a potentially fatal metastatic breast tumor would be very pleased to find, after administering a round of treatment, that the primary tumor had undergone a change in character - from aggressive to static, and no longer shedding cells that can colonize distant organs of the body.

Excess folic acid intake causes lowered immune function in aged mice

Previous studies have shown an association between high folic acid intake and a reduction in the immune system defenses needed to fight viral infections and cancer. In a new study in mice published in the Journal of Nutritional Biochemistry, scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University set out to determine if excess folic acid intake caused adverse changes in the immune system.

Research could lead to new treatment for Rett Syndrome, other forms of autism

Penn State scientists have discovered a novel drug target and have rescued functional deficits in human nerve cells derived from patients with Rett Syndrome, a severe form of autism-spectrum disorder.

Salk Institute scientists find new target for glioblastoma multiforme treatment

Glioblastoma multiforme is a particularly deadly cancer. A person diagnosed with this type of brain tumor typically survives 15 months, if given the best care. The late Senator Ted Kennedy succumbed to this disease in just over a year.

Small differences in specific genetic variant could alter nicotine consumption

Nicotine is an addictive substance and genetic factors are known to play a role in smoking behaviors. Recently, a team of researchers at Penn State and the University of Colorado determined how small differences in a particular region of the mouse genome can alter nicotine consumption.

Interpretation of images starts in the retina

Tübingen researchers have shown that image processing in the eye is more extensive than previously thought. They investigated the channels that transmit information from the eye to the brain.

Scientists reveal underlying mechanisms that lead to more difficult-to-treat symptoms of schizophrenia

Scientists at Columbia University's Mortimer B. Zuckerman Mind Brain Behavior Institute, Columbia University Medical Center, and the Université Paris Descartes have found that deficits in social memory--a crucial yet poorly understood feature of psychiatric disorders such as schizophrenia--may be due to a decrease in the number of a particular class of brain cells, called inhibitory neurons, in a little-explored region within the brain's memory center.

UF researchers reveal link between chronic stress and fat metabolism

In cell and mouse model experiments, University of Florida Health researchers have discovered that chronic stress stimulates production of betatrophin, a protein that then goes on to inhibit an enzyme involved in fat metabolism.

Researchers link idiopathic congenital nystagmus to a defect in neurocomputation

Botond Roska and his group at the Friedrich Miescher Institute for Biomedical Research implicate a clearly defined neuron type and its circuit in the retina in the pathophysiology of idiopathic congenital nystagmus.

Scientists successfully create fully-functional pancreatic cells from human skin cells

Scientists at the Gladstone Institutes and the University of California, San Francisco have successfully converted human skin cells into fully-functional pancreatic cells. The new cells produced insulin in response to changes in glucose levels, and, when transplanted into mice, the cells protected the animals from developing diabetes in a mouse model of the disease.
