Roche, ATCC partner to research real-time endogenous GPCR function with xCELLigence System

G-coupled protein receptors (GPCRs), also known as 7-transmembrane proteins, constitute the single largest class of therapeutic targets for clinical and investigational drugs. There are ~800 predicted members of this class in the human genome, involved in diverse signaling pathways in a wide array of cells and tissue types. Modulation of GPCR function has proven to have therapeutic benefit in a wide variety of diseases in immunology, neurology, cardiology, and oncology.

Discovery of new class of compounds may help fight hepatitis C

Stanford University School of Medicine scientists have discovered a novel class of compounds that, in experiments in vitro, inhibit replication of the virus responsible for hepatitis C. If these compounds prove effective in infected humans as well, they may dramatically accelerate efforts to confront this virus’s propensity to rapidly acquire drug resistance, while possibly skirting some of the troubling side effects common among therapies in current use and in late-stage development.

Green tea prevents the development of hepatic fibrosis in rat model of DMN-induced liver fibrosis

Several studies have shown that lipid peroxidation stimulates collagen production in fibroblasts and hepatic stellate cells (HSC), and plays an important role in the development of liver fibrosis. Hepatoprotective effects of green tea against carbon tetrachloride, cholestasis and alcohol induced liver fibrosis were reported in many studies. However, the hepatoprotective effect of green tea in dimethylnitrosamine (DMN)-induced models has not been studied.

Health policy research round up - Medicare and Massachusetts

Robert Wood Johnson Foundation: The Secrets of Massachusetts' Success - "By the summer of 2008, less than two years after Massachusetts' health reform law became effective, only 2.6 percent of state residents were uninsured—the lowest proportion ever recorded for any state." This study by the RWJF-funded State Health Access Reform Evaluation (SHARE) initiative "explains how national reforms can use similar methods to avoid the pitfalls that have plagued other coverage expansions."

CDC expected to revise estimated number of U.S. H1N1 deaths

Ahead of the anticipated CDC release of revised U.S. H1N1 (swine flu) death toll estimates, Reuters examines how the agency and WHO measure the impact of the virus, after both organizations "stopped trying to count actual cases months ago, once it became clear that H1N1 was a pandemic that would infect millions."
