Fisetin in murine xenograft pancreatic cancer PANC‐1 cells inhibits PANC‐1 cell proliferation, enhances AMPK/mTOR signaling pathway and stress‐induced transcription factor p8, induces autophagy (Figure 1), and increases the ATF4 and ATF6 (Jia et al., 2019). Here, MTOR is linked to pancreatic neoplasm.
