MIR138-1 is a microRNA that has been studied in various contexts [PMC4468152]. It has been found that there is no overt SC differentiation deficit in MIR138-1 cKO nerves [PMC5830491]. Mendelian randomization analysis has identified DNA methylation levels of two CpGs in the transcription activator DLX2 and micro-RNA MIR138-1, which may have causal effects on iCHD [PMC8501606]. Additionally, two CpGs near DLX2 and MIR138-1 have been identified with putative causal effects on iCHD [PMC8501606]. MIR138-1 is one of the brain-enriched microRNA-coding lncRNAs, along with precursors for MIR4500, MIR2113, MIR137, MIR548N, and MIR9-3 [PMC4468152]. The miRBase database provides information on the genes for both MIR138-1 and its homologous gene, MIR138-2 [PMC7376782]. In a study comparing brain regions, it was found that the expression of several miRNAs including MIR656, MIR29B2CHG, and ENSSTOG00000034702 decreased significantly in LT and Ar compared to IBA [PMC7848201]. This also included a decrease in expression of miR101-1 and ENSSTOG00000034702 [PMC7848201]. The genomic context of several abundant microRNAs including let7b and mir26b was explored to determine if it influenced their accumulation [PMC4057207]. It was found that let7b and mir26b displayed clusters of adenylation for mMtr4KD [PMC4057207].
