Mechanism of miR-423-5p-induced silencing of PR. (A) Methylation specific PCR of the PR promoter after treatment with miR-423-5p. U, unmethylated. M, methylated. (B) Bisulphite sequencing of the PR promoter following addition of miR-423-5p. Open circles, unmethylated CpG. Closed circles, methylated CpG. Circles represent individual CpG dinucleotides. (C) Timecourse of PR inhibition by miR-423-5p. miRNA mimics were added to cells at 25 nM.
