MiR-93 and TGFβR2 were clinically associated with NPC aggressiveness. (A) The detection of miR-93 expression by qRT-PCR in an additional set of primary NPC samples. As showed in the plot diagrams, the miR-93 expression was positively correlated with T, N classification and clinical staging. Values represent mean ± SD, *p < 0.05 (B) qRT-PCR analysis of TGFβR2 mRNA expression showed a negative correlation of TGFβR2 expression with T and N classifications and clinical staging in scatter plot diagrams. Values represent mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001.
