Abstract

[...]metastasis-preventing strategies are less effective, and metastasis is the leading cause of death amongst patients [1]. [...]reducing metastasis is urgent for improving breast cancer treatment outcomes. Furthermore, we investigated the role of miR-133b in breast cancer cells by using various functional assays and revealed their underlying mechanism in vitro. [...]we confirmed miR-133b suppressed breast cancer metastasis through targeting TIMM17A in the mouse xenograft model. RIP assays performed on MCF-7 and MDA-MB-231 cell extracts using antibodies against Ago2 further demonstrated that NEAT1 and miR-133b were all enriched in Ago2-immunoprecipitation (Ago2-IP) relative to the control (IgG-IP; Figure 2B). [...]NEAT1 overexpression decreased the levels of miR-133b while NEAT1 knockdown increased the levels of miR-133b in MCF-7 and MDA-MB-231 cells (Figure S1A and Figure 2C). In most cases, lncRNAs generally have expression patterns that are opposite to their target miRNAs [2,18]. [...]we then investigated whether NEAT1 expression is also inversely correlated with miR-133b expression in breast cancer cells and clinical specimens.
