Described as a crucial regulator in some cancers, MIR22HG has not yet been studied in laryngocarcinoma and therefore the underlying regulatory role of MIR22HG in laryngocarcinoma is worth detecting. In this study, MIR22HG expression in laryngocarcinoma cells was confirmed to be down-regulated, and up-regulated MIR22HG expression led to suppressive effects on laryngocarcinoma cell proliferation and migration. Molecular mechanism assays revealed that MIR22HG sponges miR-5000-3p in laryngocarcinoma cells. Besides, decreased expression of miR-5000-3p suppressed laryngocarcinoma cell proliferation and migration. Moreover, FBXW7 was testified to be a downstream target gene of miR-5000-3p in laryngocarcinoma cells. More importantly, rescue assays verified that FBXW7 depletion or miR-5000-3p up-regulation countervailed the repressive effects of MIR22HG overexpression on laryngocarcinoma progression. What's more, E2F6 was proved to be capable of inhibiting MIR22HG transcription in laryngocarcinoma cells. To sum up, E2F6-induced down-regulation of MIR22HG promotes laryngocarcinoma progression through miR-5000-3p/FBXW7 axis.

Recent studies have revealed that (i) RIN is indispensable for full ripening but not for the induction of ripening and (ii) the rin mutation, which produces non-ripening fruits that never turn red or soften, is not a null mutation but instead converts the encoded transcriptional activator into a repressor. Here, we have uncovered aspects of RIN function by characterizing a series of allelic mutations within
