Summary

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

MIR627 is a microRNA whose expression is influenced by the cellular environment, particularly under hypoxic conditions, as observed in hepatocellular carcinoma (HCC) cells [PMC8317525]. Research using ChIP assays with an H3K9ac antibody revealed that hypoxia leads to a decrease in H3 acetylation at the MIR627 promoter region, which correlates with the downregulation of MIR627 [PMC8317525]. This downregulation of MIR627 under hypoxia is dependent on HIF-1α; however, it does not occur through direct binding of HIF-1α to hypoxia-response elements (HRE) in the MIR627 promoter [PMC8317525]. Additionally, it was found that knockdown of HDAC3, an enzyme involved in histone deacetylation, results in increased acetylation and expression of MIR627, suggesting that HDAC3 plays a critical role in the repression of miR-627-5p during hypoxic conditions [PMC8317525'>PMC8317525]. Despite potential binding sites for HIF-1α on the MIR627 promoter region being identified and tested using ChIP and luciferase assays, no direct transcriptional activation by HIF-1α through these sites was observed [PMC8317525]. This indicates that miR-627-5p repression is mediated by mechanisms other than direct interaction with its promoter's HRE sites during hypoxia [PMC8317525].
