A: High salt intake increased the level of miR-429. * P<0.05 vs. LS. LS, low salt; HS, high salt. (n=5). B: miR-429 decreased luciferase activity when the luciferase gene was constructed with the 3′-UTR segment of PHD2. RMIC cells were co-transfected with rat PHD 2 3′-UTR luciferase reporter constructs RmiT or control 3′-UTR CmiT, and miR-429 precursor (miR-429) or scrambled miRNA precursor (Ctrl). * P<0.05 vs. cells treated with CmiT. ** P<0.05 vs. cells treated with RmiT and Ctrl. RmiT, construct of luciferase reporter with 3′-UTR of rat PHD2; CmiT, construct of luciferase reporter with scrambled 3′-UTR; Ctrl, scrambled miRNA precursor; miR-429, miRNA-429 precursor (n=4–6).
