The present study is the first to show clearly that miR-655 targets ZEB1 and TGFBR2 inducing inactivation of the TGF-b signaling pathway, involving the miR-200-ZEB1-E-cadherin axis, strongly suggesting a potential role for miR-655 as a prognostic marker and therapeutic agent in human cancers. Here, TGFBR2 is linked to cancer.
