Expression levels of miR-200a and CD47 in NPC. Notes: the expression of miR-200a was lower (a) and that of CD47 (b) was higher in NPC tissues than in nasopharyngitis samples. (c) Based on Spearman's correlation analysis, miR-200a expression was negatively correlated with CD47 levels. The expression of miR-200a was lower (d) while that of CD47 was higher (e) in NPC cells than in NP69 cells. ^∗P < 0.05 vs. the NP69 group. Abbreviations: CD47: cluster of differentiation 47; NC: negative control.
