NCAM1 and nasopharyngeal carcinoma: We found one isoform of NCAM1 at 60KDa, which was significantly decreased by the miR-27a mimic and increased by the miR-27a inhibitor (p < 0.05) in NPC (Fig. 4b and Supplementary Figs. 3, 4) The main isoform of NCAM1 at 180KDa was also increased by the miR-27a inhibitor (p < 0.05) but not decreased by miR-27a mimics in U251 (Fig. 4b and Supplementary Fig. 5).
