Researchers identify new biological pathway of H1N1 transmission to human population

A new biological pathway by which the H1N1 flu virus can make the jump from swine to humans has been discovered by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. Early test results indicate that a heretofore unknown mutation in one of the H1N1 genes may have played an important role in transmitting the virus into humans.

Comprehensive investigation employing FRET to study amino acid transporter GAT1 reported

In the December 2009 issue of the Journal of General Physiology (www.jgp.org), Moss et al. report a comprehensive investigation employing F-rster resonance energy transfer (FRET) to study the {gamma}-amino acid (GABA) transporter GAT1, a member of the family that includes transporters for neurotransmitters dopamine (DAT), serotonin (SERT), norepinephrine (NET) and glycine (GlyT).

Cells protect themselves against viruses and bacteria with novel non-genetic mechanism

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.

Shire submits a MAA for velaglucerase alfa in Europe

Shire plc, the global specialty biopharmaceutical company, today announced that it has submitted a MAA to the European Medicines Agency for velaglucerase alfa, the company's enzyme replacement therapy in development for the treatment of Type 1 Gaucher disease.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

Scientists determine how insulin resistant drugs alter core biochemical pathways through systems biology approach

Researchers from the University of California, San Diego recently offered the sharpest-yet picture of how core biochemical pathways in skeletal muscle cells and fat cells are altered in people who suffer from insulin resistance-a primary defect in type 2 diabetes and obesity. Taking a systems biology approach, the bioengineers and medical researchers also determined how a common class of drugs for treating insulin resistance-TZDs-alter these same core pathways.

Mutated IDH1 gene has novel enzyme activity consistent with cancer-causing gene: Study

Agios Pharmaceuticals today announced that its scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene. This breakthrough discovery shows that the mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate (2HG), which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers.

Raptor Pharmaceutical announces Phase 2b results of DR Cysteamine trial

Raptor Pharmaceutical Corp., today announced results from a Phase 2b clinical trial of its proprietary delayed-release cysteamine bitartrate ("DR Cysteamine") in patients with nephropathic cystinosis ("cystinosis"). The trial, conducted at the University of California, San Diego ("UCSD") General Clinical Research Center, evaluated safety, tolerability, pharmacokinetics and pharmacodynamics of a single dose of DR Cysteamine in nine cystinosis patients.
