MiR-145-5p decreases PTPRF which leads to lower STAT1 phosphorylation through direct binding of STAT1. (A) Expression of PTPRF by Western blot upon Allstars or miR-145-5p expression in different cell lines. Shown is one representative experiment. (B) Quantification of PTPRF expression normalized by GAPDH expression relative to AllStars control of each cell line (N = 3). (C) Two non-canonical coding sequence (CDS) binding sites, site #1 and site #2, in the PTPRF mRNA for miR-145-5p were identified. (D) Relative luciferase activity of two PTPRF-CDS-binding-site-reporters was measured. Results for both potential non-canonical binding sites, site #1 and site #2, are depicted in AllStars (Control) and miR-145-5p-mimic (miR-145)-transfected cells. ns: non-significant.
