We demonstrated that let-7d mimics induced DRD3 repression in a transcriptional manner.
Let-7d mimics induced DRD3 transcription and was associated to the recruitment of AGO2.
Let-7d mimics induced DRD3 transcriptional repression via DNMT1 and DNMT3b dependent DNA methylation.
H3K9me2 is involved in the let-7d induced DRD3 transcriptional gene silencing.
