Summary

Caution, this is an AI generated summary based on literature. This may have errors.

MIR627 is a microRNA that is downregulated under hypoxic conditions, as shown by a ChIP assay using an antibody against H3K9ac (histone H3 acetylation) [PMC8317525]. The decreased acetylation of histone H3 across the MIR627 promoter region correlates with the downregulation of MIR627 expression [PMC8317525]. Conversely, the knockdown of HDAC3, a histone deacetylase, leads to increased acetylation levels and expression of MIR627 [PMC8317525]. The regulation of MIR627 by hypoxia is found to be HIF-1α-dependent but not through direct binding to the hypoxia response element (HRE) sites on the MIR627 gene promoter region [PMC8317525'>PMC8317525]. Additionally, it is shown that HDAC3-mediated histone deacetylation in the promoter region of MIR627 plays a critical role in hypoxia-mediated repression of miR-627-5p [PMC8317525]. ChIP assay using an antibody against H3K9ac confirms decreased histone H3 acetylation across the MIR627 promoter region under hypoxic conditions and this repression can be reversed by HDAC3 knockdown [PMC8317525]. Furthermore, it is noted that variants in the mature miRNA sequence can result in altered target specificity, as demonstrated by a variant in the seed sequence of MIR627 [PMC4756848].
