TGF-β信号通路的组成性激活是前列腺癌(PCa)骨转移的重要机制。MicroRNAs(miRNAs)通过靶向TGF-β信号通路的下游组分,对TGF-β信号通路的激活起着重要作用。在这里,我们报告了miR-19 a-3 p在骨转移性PCa组织和细胞中下调。miR-19 a-3 p的上调在体外抑制PCa细胞的侵袭、迁移并在体内抑制骨转移。相反,沉默miR-19 a-3 p产生相反的效果。我们的研究结果进一步证明miR-19 a-3 p通过靶向TGF-β信号传导的下游效应子SMAD 2和SMAD 4抑制PCa细胞的侵袭和迁移能力,导致TGF-β信号传导失活。因此,我们的研究结果揭示了miR-19 a-3 p在PCa骨转移中诱导的抑制作用的新机制,这将有助于开发有效的癌症治疗方法。
Constitutive activation of TGF-β signaling pathway is a well-documented mechanism responsible for the bone metastasis of prostate cancer (PCa). MicroRNAs (miRNAs) have been reported to be crucial for the activation of TGF-β signaling via targeting downstream components of TGF-β signaling pathway. Here, we report that miR-19a-3p is downregulated in bone metastatic PCa tissues and cells. Upregulation of miR-19a-3p suppresses invasion, migration in vitro and inhibits bone metastasis in vivo in PCa cells. Conversely, silencing miR-19a-3p yields the opposite effect. Our results further demonstrate that miR-19a-3p inhibits invasion and migration abilities of PCa cells via targeting downstream effectors of TGF-β signaling, SMAD2 and SMAD4, resulting in the inactivation of TGF-β signaling. Therefore, our results uncover a novel mechanistic understanding of miR-19a-3p-induced suppressive role in bone metastasis of PCa, which will facilitate the development of effective cancer therapy methods against PCa.
