More importantly, transfection with the miRNA-3163 inhibitor rescued the tumor suppressive effects of MEX3A knockdown in NPC cells (P < 0.05, 0.01 or 0.001, Fig. 6G–J), indicating that miRNA-3163 is a downstream regulator of MEX3A. The gene discussed is MEX3A; the disease is nasopharyngeal carcinoma.
