Objective:To investigate the effect of vitality, invasion, cell cycle, apoptosis, DNA fragment and relative proteins expression in gastric cancer SGC-7901 and pancreatic cancer PANC-1 cell line by sulforaphane(SFN)derived from broccoli, to provide reference for daily diet and supply experiment data for treatment gastric cancer and pancreatic cancer. Methods:Analyzed vitality and invasion of SGC-7901 and PANC-1 cells treated with sulforaphane by cell counting kit (CCK8) and transwell, then measure the half maximal (50%) inhibitory concentration (IC50) of sulforaphane for SGC-7901 and PANC-1 cells. The cells cycle, apoptosis and DNA fragment were analyzed using Flow Cytometry Analysis and agarose electrophoresis, TNF-α, TGF-β and NF-κB were analyzed by western blot and immunohistochemistry after treatment with sulforaphane. Results:Results showed that SGC-7901 and PANC-1 cells proliferate and invade were inhibited by sulforaphane with a dose-dependent manner, IC50 of sulforaphane was 4.5μg/mL(SGC-7901,24h) and 5.5μg/mL (PANC-1,24h), and the cell cycle were arrested at G0/G1 phase. 4.5μg/mL and 5.5μg/mL sulforaphane induced apoptosis, DNA fragment, decreased the expression of TNF-α, TGF-β and NF-κB in SGC-7901 and PANC-1 cells. Conclusion: Sulforaphane inhibited proliferation and invasion of gastric cancer SGC-7901 and pancreatic cancer PANC-1 cells in vitro, decreased the expression of inflammation proteins, maybe a novel chemotherapy for gastric cancer and pancreatic cancer.
