New study reveals PTPN2 gene loss causes bone cancer

In patients with leukemia, the formation of white blood cells in the bone marrow is disrupted. This makes leukemia patients particularly susceptible to infections, because properly functioning white blood cells ensure protection against intruders such as viruses and bacteria.

PROVENGE receives FDA approval for treatment of CRPC

Dendreon Corporation today announced that the U.S. Food and Drug Administration has approved PROVENGE (sipuleucel-T), an autologous cellular immunotherapy for the treatment of asymptomatic or minimally symptomatic metastatic, castrate-resistant (hormone-refractory) prostate cancer.

New theory on muscle and bone diseases

Traditionally, doctors and clinicians thought diseases that affect muscles or bones affected those areas specifically. For example, bone diseases only affect bones, or muscle diseases only concerned muscles. But recent evidence supports the notion that bones and muscles are more interconnected than previously thought.

Study: Cigarette smoking, fructose consumption can worsen NAFLD

Recent studies suggest that modifiable risk factors such as cigarette smoking and fructose consumption can worsen nonalcoholic fatty liver disease. With NAFLD, fat accumulates in the liver of overweight individuals despite drinking little alcohol, causing in some cases liver scarring that can lead to liver failure.

ADDF grants Signum Biosciences $270,000 for evaluating PP2A-modulatory compounds as AD therapeutics

The Alzheimer's Drug Discovery Foundation (ADDF) announced today that it is providing a grant of $270,000 to Signum Biosciences, Inc. (Princeton, NJ) to evaluate small-molecule, orally delivered Protein Phosphatase 2a (PP2A)-modulatory compounds as disease-modifying therapeutics for Alzheimer's disease.

Working of master regulator protein phosphatase 1

Protein phosphorylation is a process by which proteins are flipped from one activation state to another. It is a crucial function for most living beings, since phosphorylation controls nearly every cellular process, including metabolism, gene transcription, cell-cycle progression, cytoskeletal rearrangement and cell movement.

TB's mechanism to evade body's immune system identified

Indiana University School of Medicine researchers have identified a mechanism used by the tuberculosis bacterium to evade the body's immune system and have identified a compound that blocks the bacterium's ability to survive in the host, which could lead to new drugs to treat tuberculosis.

Study could lead to non-surgical alternatives for tonsillectomies

Children with obstructive sleep apnea (OSA) may one day be able to have an injection or use a throat spray instead of getting their tonsils removed to cure their snoring, according to a new study from the University of Chicago, which found that a specific gene product may be responsible for the proliferation of adenotonsillar tissue that can cause pediatric OSA.

Breakthrough findings could lead to new treatments for prostate, brain and skin cancers

Researchers at the Lady Davis Institute for Medical Research of the Jewish General Hospital and McGill University in Montreal have discovered a previously unsuspected link between two different genetic pathways which suppress the growth of cancer tumours.

GIVI scientists discover anti-HIV molecule that enhances infection, reduces transmission

Scientists at the Gladstone Institute of Virology and Immunology (GIVI) have discovered a new agent that might inhibit the infectivity of HIV. The agent, surfen, impairs the action of a factor in semen that greatly enhances the viral infection.

Phosphatases can prevent inflammation and formation of blood clots

Polyphosphate from blood platelets plays a key role in inflammation and the formation of blood clots, scientists from the Swedish medical university Karolinska Institutet have shown. The study, which is presented in the prestigious scientific journal Cell, describes how this mechanism can be used in treatment.

Positive results from Isis Pharmaceuticals' ISIS 113715 Phase 2 study in type 2 diabetes patients

Isis Pharmaceuticals, Inc. today announced positive top-line results from a Phase 2 study evaluating the safety and efficacy of ISIS 113715 in patients with type 2 diabetes. ISIS 113715 is a novel insulin sensitizer that reduces the expression of protein tyrosine phosphatase-1B (PTP-1B). The study showed consistent and statistically significant reductions in multiple short and intermediate measures of glucose control.

PP5 enzyme decrease in neurons can cause cell death in Alzheimer's disease patients

A Purdue University researcher has discovered that the amount of an enzyme present in neurons can affect the mechanism thought to cause cell death in Alzheimer's disease patients and may have applications for other diseases such as stroke and heart attack.

Genetic factors play an important role in the development of type 1 diabetes

Under the direction of Prof. Dr. Anette Ziegler, scientists of the Diabetes Research Group at Helmholtz Zentrum München and Technische Universität München investigated the formation of antibodies to a zinc transporter in children with elevated risk for type 1 diabetes. The study provided indications of an early onset of the disease when specific antibodies in the blood and specific variants of the associated zinc transporter are present in the genome.
