The relationship among circ-FOXM1, miR-149-5p, and ATG5. (a and b) The expression of ATG5 was determined in H1581 cells transfected with sh-circ-NC, sh-circ-FOXM1, sh-circ-FOXM1 + Anti-miR-NC, or sh-circ-FOXM1 + Anti-miR-149-5p, respectively; ANOVA followed via Tukey’s test was performed for statistical analysis. (c and d) The expression of ATG5 was detected in A549 cells transfected with Vector, circ-FOXM1, circ-FOXM1 + miR-NC, or circ-FOXM1 + miR-149-5p, respectively; ANOVA followed via Tukey’s test was performed for statistical analysis. *P < 0.05
