To further determine whether miR-19b-3p regulates the translation of TNFAIP3, we transfected CNE1 and CNE2 cells with miR-19b-3p mimic and NC mimic, whereas NPC cells were transfected with miR-19b-3p inhibitor and NC inhibitor. The gene discussed is TNFAIP3; the disease is nasopharyngeal carcinoma.
