E. miR-10b mimic regulates 5'UTR Luciferase reporters of some splicing factors genes bearing wild type (WT), but not mutated (Mut) miR-10b binding sites. Statistical significance of the differences was determined by Student's t test, with p-values < 0.05 indicated by asterisks, p < 0.01 by two asterisks, and p< 0.001 by three asterisks. Numbers of replicates and exact P-values are included in Appendix Table S4.
