Additionally, molecular analysis suggested that sh-circUBAP2 notably reduced the expression of circUBAP2 and SOX4, but elevated miR-361-3p expression in tumor masses compared with the sh-NC group (Fig. 6d, e), revealing circUBAP2 knockdown suppressed CC tumor growth in vivo by regulating miR-361-3p and SOX4 expression. This evidence concerns the gene SOX4 and neoplasm.
