Regulation and Function of miR-218 in Gastric Cancer Metastasis
Tie, Pan et al., PLoS Genetics
Researchers describe a negative feedback system between Robo1, a Slit receptor, and miR-218, wherein “decreased miR-218 levels eliminate Robo1 repression, which activates the Slit-Robo1 pathway through the interaction between Robo1 and Slit2, thus triggering tumor metastasis.” The authors suggest that the restoration of miR-218 supresses Robo1 espression and inhibits tumor cell invasion.
Medco Acquires DNA Direct to Expand PGx Offerings with Genetic Education, Testing Decision Support
Already a pioneer in incorporating pharmacogenetic testing into its PBM programs, Medco's decision to buy DNA Direct signals its intent to be a "one-stop shop" for payors and employers interested in using genetically guided medicine to make healthcare more efficient and lower costs.
