CD82/KAI1是tetraspanin超家族的成员,是一种转移抑制因子,CD82通过下调几种卷曲(FZD)亚型抑制典型Wnt信号,导致细胞膜上β-catenin的积累。在本研究中,我们通过检测microRNAs (miRNAs)的作用来研究CD82抑制FZD表达的机制。miRanda算法从FZD序列中预测了11个mirna。其中,与对照细胞相比,CD82导致miR-203上调(2.095倍),miR-338-3p下调(0.354倍)。转染miR-203和miR338-3p模拟物或抑制剂后发现,miR-203下调FZD2 mRNA(0.268倍)和蛋白表达(0.701倍)。此外,转染miR-203模拟物也能抑制细胞迁移。因此,这些发现提示CD82可增强miR-203的表达,并直接下调FZD2的表达,通过抑制Wnt信号通路抑制肿瘤转移。
CD82/KAI1, a member of the tetraspanin superfamily, is a suppressor of metastasis and CD82 inhibits canonical Wnt signaling via downregulation of several Frizzled (FZD) isoforms, resulting in accumulation of β-catenin at the cell membrane. In this study, we investigated the mechanism through which CD82 inhibited FZD expression by examining the effects of microRNAs (miRNAs). The miRanda algorithm predicted 11 miRNAs from FZD sequences. Among these miRNAs, CD82 caused upregulation of miR-203 (by 2.095-fold) and downregulation of miR-338-3p (by 0.354-fold) as compared with control cells. Transfection with miR-203 and miR338-3p mimics or inhibitors revealed that miR-203 downregulated FZD2 mRNA (by 0.268-fold) and protein expression (by 0.701-fold). Moreover, transfection with the miR-203 mimic also inhibited cell migration. Therefore, these findings suggested that CD82 enhanced the expression of miR-203 and directly downregulate FZD2 expression, suppressing cancer metastasis by inhibition of the Wnt signaling pathway.
