HGF and cancer: Piceatannol exhibits greater inhibitory effects on cancer cells compared to normal cells. The IC50 values for cancer cell lines were 63 μM for HSC-2, 232 μM for HSC-3, 373 μM for HSG, and 11 μM for HL-60 cells. In contrast, the IC50 values for normal cells were 367 μM for HGF, 414 μM for HPC, and >1000 μM for HPLF cells.
