High avidity of bone metastasis is an important characteristic in prostate cancer
(PCa). Downexpression of miR-133b has been reported to be implicated in the
development, progression and recurrence in PCa. However, clinical significance
and biological roles of miR-133b in bone metastasis of PCa remain unclear. Here
we report that miR-133b is downregulated in PCa tissues and further decreased in
bone metastatic PCa tissues. Downexpression of miR-133b positively correlates
with advanced clinicopathological characteristics and shorter bone
metastasis-free survival in PCa patients. Upregulating miR-133b inhibits
invasion, migration in vitro and bone metastasis in vivo in PCa cells.
Mechanistically, we find that miR-133b suppresses activity of TGF-? signaling via
directly targeting TGF-? receptor I and II, which further inhibits bone
metastasis of PCa cells. Our results further reveal that overexpression of REST
contributes to miR-133b downexpression via transcriptional repression in PCa
tissues. Importantly, silencing miR-133b enhances invasion and migration
abilities in vitro and bone metastasis ability in vivo in REST-silenced PCa
cells. The clinical correlation of miR-133b with TGFBRI, TGFBRII, REST and TGF-?
signaling activity is verified in PCa tissues. Therefore, our results uncover a
novel mechanism of miR-133b downexpression that REST transcriptionally inhibits
miR-133b expression in PCa cells, and meanwhile support the notion that
administration of miR-133b may serve as a rational regimen in the treatment of
PCa bone metastasis.
