The effect of Fufangkushen on gastric cancer cell killing by lines SGC-7901 human γδT cell

Objective To explore the effect of Fufangkushen on gastric cancer cell killing by human γδT cells. Methods Isopentenyl pyrophosphate method was used to amplify human peripheral blood γδT cells in vitro. Fufangkushen at various concentrations was used to induce γδT cells and gastric cancer cell lines SGC-7901 for 24 hours, MTr assays was used to detect inhibitory effect of Fufangkushen on these cell lines, LDH assays was used to measure the cytotoxic activity of γδT cells, and flow cytometry was used to detect apoptosis of γδT cells and SGC-7901 before and after the treatment. Results Ten days after cultivation, proliferation ra-tio of γδT cells increased from 4.21% to 70.35% and CD44 was up to 94.0%. Inhibitory rate of Fufangkush-en on SGC-7901 at various concentrations was significantly higher than that on γδT cells (22.3% vs-22.4%, P<0.05). The negative inhibitory ratio on γδT cells showed a dose-dependent manner with Fufangkushen's concentrations ranging from 1/5 to 1/400. γδT cells cytotoxic activity to SGC-7901 induced by Fufangkushen for 24 h was higher than control group, (83.6% vs 71.2%, P<0.05). Apoptotic rate was significantly lower in γδT cells than in SGC-7901 (4.64% vs49.23%, P<0.05). Conclusion Fufangkushen, within routine concentration ranges, can promote γδT cells' proliferation, inhibit tumor cell growth and enhance γδT cells' cytotoxic activity. This may be beneficial to tumor adoptive immunotherapy and provide evidence for the appli-cation of Fufangkushen in the treatment of tumors.
