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.
Array Companies Upgrade H1N1 Flu Chips Despite Uncertain Market Opportunity
While companies selling array-based tests, including CombiMatrix, Arrayit, and Veredus Labs, are keen to make their platforms available to laboratories for identifying the flu strain, the FDA has only given emergency use authorization for a PCR-based test. Moreover, companies that sell flu chips are unlikely to see their technology adopted unless the current swine flu strain mutates, according to some sources.
