TNFAIP3 and nasopharyngeal carcinoma: We then performed colony formation assays by co-transfecting miR-19b-3p inhibitor and siR-TNFAIP3 into NPC cell lines, which showed that decreased expression of TNFAIP3 restored the significant improvement in radiosensitivity by downregulating miR-19b-3p expression [AUC 3.585 (CNE1.inhibitor plus siRNA) vs 2.857 (CNE1.inhibitor plus siRNA.NC), RPF = 1.25 AUC 2.99 (CNE1.inhibitor plus siRNA) vs 2.54 (CNE1.inhibitor plus siRNA.NC), RPF = 1.18; p < 0.05] (Fig. 7e).
