Expression of let-7a and HMGA2 in NPC clinical samples. (A-B) Let-7a was downregulated and HMGA2 was upregulated in NPC (n = 48) compared with normal nasopharyngeal epithelial tissues (n = 20). Data is presented as the mean ± SD, and P values were calculated with the Student t-test. (C) Significant correlations between the expression of let-7a and HMGA2 in NPC (n = 48) were demonstrated using the Pearson’s correlation coefficient analysis (r = −0.385, P = 0.007).
