Description

Homo sapiens hsa-mir-125b-1 precursor miRNA

Summary

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

MIR125B1 is a miRNA gene that has been reported as dysregulated in Alzheimer's disease (AD) brains [PMC4861808]. Ten CpG sites, including cg03891346, overlap with miRNA genes that have been previously reported as dysregulated in AD brains, such as MIR34B/C, MIR9-1, MIR34A, MIR146B, MIR124-1, MIR181C/D, MIR451, and MIR9-3 [PMC4861808]. Specifically, cg03891346 annotated to MIR125B1 has been associated with the expression level of miR-100-5p [PMC7056871]. These findings suggest a potential role of dysregulated miRNA genes in the pathogenesis of AD [PMC4861808]. Further research is needed to understand the specific mechanisms by which these dysregulated miRNAs contribute to the development and progression of AD [PMC4861808].
