The ROCK isoforms differentially regulated the pathways of RhoA/ROCK1/p-MLC and RhoA/ROCK2/p-cofilin in a coordinate fashion to modulate breast cancer cell motility in a substrate stiffness-dependent manner through integrin β1-activated FAK signaling.
The aim of this study is to evaluate the TGF-β1 action model for induction of EMT and the action of metformin and ROCK-1 inhibitor (Y27632) in EMT process in breast cancer cell lines.
In conclusion, our results confirmed that the <i>CCR2</i> 3'UTR acts as a metastasis suppressor by acting as a ceRNA for STARD13 and thus inhibiting RhoA-ROCK1-MLC-F-actin pathway in breast cancer cells.This article has an associated First Person interview with the first author of the paper.
Over-expression of key genes such as c-MYC and CTNNB1 (encoding β-catenin) in Wnt/β-catenin-dependent and ROCK1 in Wnt/β-catenin-independent signaling pathways (Rho/Rho-associated kinase (ROCK) signaling pathway) has already been identified as the hallmarks of many tumors, and their role in breast cancer has also been investigated and confirmed. miR-340 characterization as an onco-suppressor miRNA has been previously reported.
Our findings indicate that miR-145 acts as a tumor suppressor and its downregulation in tumor tissues may contribute to the progression of breast cancer through a mechanism involving ROCK1, suggesting miR-145 as a potential new diagnostic and therapeutic target for the treatment of breast cancer.
