High expression of circ-FOXM1 and low expression of miR-143-3p were observed in melanoma tissues and cells. a, b The expression level of circ-FOXM1 in melanoma tissues and cells and matched normal tissues and cells was determined by qRT-PCR. c, d The expression level of miR-143-3p in melanoma tissues and cells and matched normal tissues and cells was determined by qRT-PCR. e The correlation between circ-FOXM1 and miR-143-3p was analyzed by Spearman’s correlation coefficient analysis. *P < 0.05
