Solanine Inhibits Immune Escape Mediated by Hepatoma Treg Cells via the TGFβ/Smad Signaling Pathway

Figure 2

Liver cancer cells release more TGFβ than normal stem cells. (a) Compared with normal liver cells (LO2) and liver cancer cells (HepG2, SMMC-7721, Hep3B, BEL-7402, and H22), TGFβ content was detected. (b) Structural formula of solanine. (c) Solanine treats liver cancer cells and inhibits TGFβ. and .
