LIF and liver cancer: Our results showed that Raloxifene did not inhibit the phosphorylation of STAT3 induced by LIF (Figure 2A), or affect the level of STAT1 phosphorylation induced by IFN-γ (Figure 2B) and IFN-α (Figure 2C), and had no effect on STAT6 phosphorylation induced by IL-4 (Figure 2D) in Hep-3B liver cancer cells.
