FDA grants IND for AEZS-130 Phase 2A trial in cancer cachexia

Aeterna Zentaris Inc. today announced that the U.S. Food and Drug Administration has granted Jose M. Garcia, MD, PhD, Assistant Professor, Division of Diabetes Endocrinology and Metabolism, Departments of Medicine and Molecular and Cell Biology, Baylor College of Medicine and Michael I. DeBakey Veterans Administration Medical Center, in Houston Texas, an Investigational New Drug approval for the initiation of a Phase 2A trial to assess the safety and efficacy of repeated doses of the Company's ghrelin agonist, AEZS-130, in patients with cancer cachexia.

Scientists decode how Machado-Joseph disease arises

Neurodegenerative diseases represent one of the greatest challenges of our aging society. However, investigation into these diseases is made particularly difficult due to the limited availability of human brain tissue. Scientists from the Life & Brain Research Center and Neurology Clinic of Bonn University have now taken a roundabout path: They reprogrammed skin cells from patients with a hereditary movement disorder into so-called induced pluripotent stem cells (iPS cells) and obtained functional nerve cells from them.

Dendritic cells play a novel protective role in pancreas

NYU Langone Medical Center researchers have discovered the novel protective role dendritic cells play in the pancreas. The new study, published in the November issue of journal Gastroenterology, shows dendritic cells can safeguard the pancreas against acute pancreatitis, a sudden dangerous swelling and inflammation of the pancreas gland.

Eurozone cancer researchers praise AICR for vital grants

AS the ripples from the ongoing crisis in the eurozone continue to spread, cancer researchers in the countries worst affected warned today that their work would have stalled without vital grants from a Scottish charity.

Researchers identify protein that affects production of extracellular vesicles

Researchers at NYU Langone Medical Center have discovered a protein called TAT-5 that affects the production of extracellular vesicles, small sacs of membrane released from the surface of cells, capable of sending signals to other cells.

New stem cell technique hopes to replace damaged cells in Parkinson's

Australian scientists have developed a new technique using stem cells, in the hope to replace damaged cells in Parkinson's disease. The technique could be developed for application in other degenerative conditions.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

Study reveals what causes lysosome to overflow in Batten disease

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood.

Cypin protein may prevent long-term brain damage after stroke

One of two proteins that regulate nerve cells and assist in overall brain function may be the key to preventing long-term damage as a result of a stroke, the leading cause of disability and third leading cause of death in the United States.

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

Study uncovers mTOR's complex signaling pathway

Even yeast understand austerity. A finely tuned system evolved early on to help cells survive in a world where good times come as fast as they go. The system, a molecular switch found in organisms from yeast to humans, involves a nutrient-sensing protein that turns growth on in times of plenty and shuts it off when times are lean.
