CircABCB10 targeted the regulation of miR-670-3p expression in HCC cell lines. a Starbase predicts putative targeting sites for circABCB10 and miR-670-3p. b Analysis of luciferase activity in Huh7 and HepG2 cells co-transfected with miR-670-3p mimic and pmirgLO-circABCB10-WT or pmirgLO-circABCB10-Mut vector. P < 0.01 by t-test. c miR-670-3p expression levels in Huh7 and HepG2 cells with circABCB10 knockdown or overexpression. P < 0.01 by t-test. d, e Expression level of miR-670-3p in HCC tissues and adjacent normal tissues in our cohort (n = 40) or TCGA data from UALCAN (http://ualcan.path.uab.edu). P < 0.01 and P < 0.001 by Wilcoxon test and t-test, respectively. f Spearman correlation analysis of circABCB10 and miR-670-3p in HCC tissues (n = 40) (Spearman r = − 0.4723; P < 0.01).**P < 0.01, *** P < 0.001
