摘要: 目的:探讨皖南蝮蛇毒抑瘤组分-I(agkistrodon halys venom antitumor component-I, AHVAC-I)抑制胃癌细胞迁移的生物学活性。方法:组织块培养法和胰酶消化法分离培养人原代胃癌相关成纤维细胞(GCAFs);CCK8实验根据半数抑制浓度(IC50)确定AHVAC-I实验浓度;收集AHVAC-I作用GCAFs后的上清液(GCAFs-CMAHVAC-I),划痕实验法和Transwell检测GCAFs-CMAHVAC-I抑制胃癌细胞株MKN-28迁移的能力;用ELISA、RT-PCR检测AHVAC-I作用后GCAFs分泌产生的趋化因子CXCL12。结果:AHVAC-I可显著抑制人原代GCAFs分泌的CXCL12(P<0.05),AHVAC-I作用后生成的GCAFs-CMAHVAC-I明显抑制了胃癌细胞MKN-28的迁移能力(P<0.05)。 结论:AHVAC-I能够通过抑制GCAFs分泌生成的CXCL12抑制胃癌细胞MKN-28的迁移能力,逆转胃癌肿瘤微环境中的GCAFs的促进胃癌细胞转移的作用。

Abstract: AIM: To explore whether Agkistrodon Halys venom antitumor component-I (AHVAC-I) affects the migration of gastric cancer cells by human primary gastric cancer-associated fibroblast (GCAFs).  METHODS: Tissue block culture and trypsin digestion were used to separate and culture human primary gastric cancer-associated fibroblasts (GCAFs);  the GCAFs-CMAHVAC-I  was collected after AHVAC-I treatment to culture the MKN28 cells. Migration was evaluated by wound-healing and Transwell assay. ELISA and RT-PCR were used to verify wether AHVAC-I can play a role in the production of CXCL12 from GCAFs.RESULTS: AHVAC-I can decrease the CXCL12 production from GCAFs (P<0.05). Cultured with GCAFs-CMAHVAC-I , the migration of MKN28 cells were significantly inhibited (P<0.05). CONCLUSION: AHVAC-I can inhibit the migration ability of gastric cancer cells MKN-28 by decreasing CXCL12 production from GCAFs, and is valuable for gastric cancer therapy.

Key words: agkistrodon halys venom antitumor component-I, gastric cancer-associated fibroblast, gastric cancer cell migration, chemokine CXCL12
