Fig. 3. ADAR1-dependent A-to-I editing of canonical miR-3144-3p in liver cancer.
a Representative integrative genomics viewer (IGV) image of A-to-I edited sites in the primary mir-3144 (upper) sequence and seed region of mature miR-3144 (lower) in liver cancer patients. Red indicates a major editing site in precursor mir-3144. b Direct sequencing analyses after ADAR1 knockdown in liver cancer cell lines with high ADAR1 expression. c RNA immunoprecipitation assay with ADAR1-overexpressing cells. The fold enrichment of primary mir-3144 was measured by qRT-PCR and normalized to the level of GAPDH. d Direct sequencing analyses of miR-3144-3p in wild-type or mutant ADAR1-overexpressing cells. All data are shown as the mean ± SEM; *P < 0.05, ***P < 0.001 by unpaired Student’s t-test.
