Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment

以抗体阻断integrin ？3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞，发现在JA处理下的OC-2，其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少，利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ？3，使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。
