We observed a potent induction of STAT3 phosphorylation upon exposure of mucoepidermoid carcinoma cells (UM-HMC-3A,-3B) to endothelial-conditioned medium, which was partially blocked in a dose-dependent manner with increasing concentrations of tocilizumab (Figure 4F and 4G). This evidence concerns the gene STAT3 and mucoepidermoid carcinoma.
