AFAP1 and nasopharyngeal carcinoma: Real-time PCR showed that FOSL2 was also overexpressed in those 32 NPC clinical samples compared with nontumor nasopharyngeal epithelial samples and tightly positively associated with the TNM stages, the T stages, and lymphoma metastasis in patients with NPC (Fig. 6a), positively correlated with the AFAP1-AS1 expression (Fig. 6b) while negatively correlated with miR-423-5p (Fig. 6c).
