Inhibition of PR by miR-423-5p requires seed sequence complementarity. (A) Alignment of miR-423-5p with ncRNA overlapping the PR promoter (seed sequence shown in lower case). (B) PhastCons conservation analysis of the miR-423-5p target site within the PR promoter (seed sequence target site underlined, sequence listed 3′ to 5′). (C) Alignment of mutant miR-423-5p mimics with ncRNA overlapping the PR promoter (mismatched bases underlined). (D) RT–qPCR measuring PR mRNA expression following treatment with mutant miR-423-5p mimics. (E) RT–qPCR measuring PR mRNA expression following treatment with a DNA analog of miR-423-5p. Duplexes were added to cells at 25 nM. Error bars indicate SD (n = 3). P-values were calculated using the two-tailed unpaired Student's t-test with equal variances. **P < 0.01.
