MIR200A is a regulatory gene that is involved in epithelial cell function [PMC7948487]. In a study conducted on A549 cells, the state of H3K36 methylation was examined on the regulatory regions of various epithelial genes, including CDH1, MIR200A, CGN, and the unrelated GAPDH gene [PMC7948487]. In another study involving mesangial cells treated with high glucose and kidneys in diabetic mice models, it was observed that MIR200A was downregulated [PMC5590408]. This downregulation of MIR200A was accompanied by an upregulation of miR-377 and a downregulation of miR-141 [PMC5590408]. These findings suggest that MIR200A may play a role in the regulation of gene expression in epithelial cells and may be involved in diabetic kidney disease [PMC5590408]. Further research is needed to fully understand the mechanisms by which MIR200A influences gene expression and its potential implications for disease pathology.
