Tang et al. found that circ_SETD3 competitively adsorbs to miR-615-5p and miR-1538 and negates their inhibitory effects on microtubule-associated protein RP/EB family member 1 (MAPRE1) mRNA, thereby upregulating the expression of MAPRE1 and enhancing the invasion and migration capabilities of nasopharyngeal carcinoma (NPC) cells [132]. Here, MAPRE1 is linked to nasopharyngeal carcinoma.
