INS and hepatocellular carcinoma: To better characterize the role of miR-155 in regulating insulin sensitivity in liver and SM, we performed in vitro glucose uptake assays [i.e., 18F-FDG (fluoro-D-glucose) uptake assays] using human hepatocellular carcinoma 7402 cells, and murine hepa1-6 and C2C12 cell lines.
