Toxic levels of Alzheimer's clusters in brain determined

Scientists have long suspected that Alzheimer's disease (AD) is caused by a small protein called the amyloid β-protein (Aβ). This protein clumps or binds to itself, eventually changing chemically to create brain protein deposits (plaques) that are characteristic of AD.

Easy-to-swallow drug restores autoimmune function in diabetics

Found in 30% of all human cancer tumors, the Ras protein literally "drives cells crazy," says Prof. Yoel Kloog, the dean of the Faculty of Life Sciences at Tel Aviv University. Prof. Kloog was the first in the world to develop an effective anti-Ras drug against pancreatic cancer, currently in clinical trials. Now, new research published in the June issue of the European Journal of Pharmacology shows that the drug might be able to slow the progression of diabetes as well.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

New molecule blocks lymphangiogenesis

Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.

Eiger Biopharmaceuticals starts CLEAN-1 HCV phase 1B trial

Eiger BioPharmaceuticals, Inc., a biotechnology company developing antiviral therapies, announced today that the first patients have been dosed in an innovative clinical trial in patients chronically infected with the hepatitis C virus (HCV). The trial, run in centers in Australia and New Zealand, will investigate the antiviral effect of clemizole monotherapy in the absence of interferon.

Estrogen-dependent switch tempers killing activity of immune cells

The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells (CTLs), which are known to attack tumor cells and cells infected by viruses. The key player in this process is a cytotoxic T cell molecule which has been known for a long time and which scientists have named EBAG9.

Array Biopharma reports Q4 and full year 2009 financials

Array reported revenue of $5.5 million for the fourth quarter of fiscal 2009, compared to revenue of $6.1 million for the same period in fiscal 2008. Array invested $21.3 million in proprietary research and development for the quarter to advance its seven wholly-owned drugs in clinical development and select discovery programs.

Chemists rationally design inhibitors against an RNA molecule that causes myotonic muscular dystrophy

Chemists at the University at Buffalo have used rational drug design to synthesize small, cell-permeable molecules that are effective in vitro against two common types of myotonic muscular dystrophy, a result that has implications for potentially curing muscular dystrophy, as well as other diseases.

NIH stimulus funding supports Emory - grants to advance research, create jobs, support students

At least 50 research projects so far, supported by more than $10 million in stimulus grants from the National Institutes of Health, are expected to lead to new discoveries at Emory University that will improve medical treatment, create new jobs, and provide additional educational opportunities for students. Emory has received half of all the NIH ARRA grants awarded to Georgia academic institutions thus far.

Scientists find key to strengthening immune response to chronic infection

A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.

Bellicum Pharmaceuticals starts phase I/II trial of novel advanced prostate cancer vaccine

Bellicum Pharmaceuticals, Inc. today announced dosing of the first patient in a Phase I/II clinical trial of BP-GMAX-CD1, a novel pharmacologically regulated dendritic cell vaccine for the treatment of prostate cancer. The disease-specific trial is being conducted under a Bellicum Investigational New Drug application allowed by the FDA in 2008. The company anticipates reporting initial results of the study in 2010.

Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Aptamers offer unique therapeutic advantages

A novel class of drugs composed of single strands of DNA or RNA, called aptamers, can bind protein targets with a high strength and specificity and are currently in clinical development as treatments for a broad range of common diseases, as described in a comprehensive review article published online ahead of print in Oligonucleotides.
