RETN and hepatocellular carcinoma: In the present study, we have demonstrated that (a) resistin has no inhibitory effects on the viability of SK-Hep1 cells (see Additional file 1) and (b) resistin has capability to induce the adhesion of SK-Hep1 cell to the endothelial cells and hence we have speculated that resistin might be an important mediator for initiating the HCC metastasis.
