Figure 4. miR-17-92 cluster members differentially target the 3′-UTR sequences of voltage-gated potassium channels and modulatory subunits.

Figure 4

(a) List of voltage-gated potassium channel subunits predicted as miR-17-92 target genes; these subunits were reportedly downregulated in a previous microarray study of SNL20. Parenthesized targeting miRNAs represent predicted miRNAs not validated by a luciferase assay. (b) Activities of luciferase with voltage-gated potassium channel subunit 3′-UTRs or mutated 3′-UTRs in HEK293 cells co-transfected with control or miR-17-92 cluster member-expressing plasmid vector. Numbers of cell cultures are indicated at the base of each bar. Error bars are s.e.m. *P<0.05, **P<0.01 and ***P<0.001 (Kcna1, P<0.001 for miR-18a and P=0.004 for miR-92a; Kcna4, P<0.001 for miR-19a and P<0.001 for miR-19b; Kcnc4, P<0.001 for miR-19a, P<0.001 for miR-19b and P<0.001 for miR-92a; Kcnd3, P=0.021 for miR-18a; Kcnq5, P=0.008 for miR-19a and P=0.008 for miR-19b; Dpp10, P=0.006 for miR-92a; Scn1b, P<0.001 for miR-19a and P<0.001 for miR-19b) compared with control plasmid, unpaired t-test or Dunnett’s test.
