MIR1264: MIR1264 is a microRNA that is downregulated in response to treatment with UA-Exos, as shown by RT-qPCR analysis [PMC7974330]. It has been identified as a direct target of circRNA-0006896, which contains a putative binding site for MIR1264 in its 3'-UTR [PMC7974330]. Co-transfection of wild-type circRNA-0006896 with MIR1264 mimics leads to a significant reduction in fluorescence intensity, indicating the specific function of circRNA-0006896 as a sponge for MIR1264 [PMC7974330]. The upregulation of circRNA-0006896 in UA-Exos upregulates the expression levels of 122 mRNA molecules by reducing the expression of MIR1264 [PMC7974330]. Additionally, MIR1264 has been identified as a direct target of DNMT1, which can bind to the 3'-UTR of DNMT1 transcript to inhibit its expression [PMC7974330]. The upregulation of circRNA_0006896 in HUVECs is accompanied by downregulated expression of MIR1264 and upregulated expression of DNMT1 mRNA [PMC9953235]. The sponging effect of hsa_circ_0060927 on MIR1264 leads to an increase in DNMT1 transcripts and subsequent hypermethylation of SOCS3 gene, which may contribute to uterine leiomyoma pathology [PMC7171336]. Overall, these findings highlight the regulatory role and potential implications of MIR1264 and its interactions with circRNAs and target genes.
