Thus, PANDA depletion leads to senescence phenotypes by derepression of p21 due to disruption of SAFA-PANDA-PRC interactions.
In this study, we determined that H19 competitively binds to miR-200a, suggesting that H19-mediated derepression of [beta]-catenin is a potential mechanism by which this lncRNA promotes cell proliferation in CRC.
Over the past several years, increasing studies are focusing on the lncRNA-miRNA-mRNA regulatory mechanism that lncRNAs may serve as competing endogenous RNAs (ceRNAs), namely, miRNA sponges or antagomirs, to negatively regulate miRNAs, eventually resulting in the derepression of miRNA targets [21].
Notably, when these regulatory lncRNAs are repressed the result can be a concomitant activation of their protein-coding counter parts expression as a result of derepression of the lncRNA-targeted locus.

The consequence of such derepression would lead to reduction of Chop/CHOP and Atf3/ATF3 mRNA and protein expression.
Derepression of c-Fos caused by microRNA139 down-regulation contributes to the metastasis of human hepatocellular carcinoma.
(64) However, gene deprivation of EZH2 did not induce derepression of HoxA9 expression unlike that of ASXL1 despite the fact that EZH2 and ASXL1 collaborate in repressing gene expression through EZH2-mediated H3K27me3.
