Zusammenfassung
Background/Aims: Far upstream element (FUSE) binding protein (FBP)-1 and FBP-2 are potent regulators of hepatocellular carcinoma (HCC) cell proliferation and cell motility, respectively. In this study we aimed to analyze the expression, functional relevance, and regulation of FBP-3, another FBP family member in human hepatocarcinogenesis. Methods: Expression of FBP-3 was analyzed in normal livers, dysplastic nodules and HCCs. Functional consequences after RNAi-mediated reduction of FBP-3 on HCC cell proliferation, viability, and migration were analyzed. In order to identify potential upstream regulators of FBP-3…
