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.
