Fig. 3: Differential expression levels and the correlation of circ-GRB10 and miR-328-5p.

a The expression of circ-GRB10 in NP tissues was measured in 20 patients and 20 controls using qRT-PCR (***P < 0.001). b The expression of miR-328-5p was significantly upregulated in degenerative NP tissues (***P < 0.001). c circ-GRB10 expression was significantly negative correlated with miR-328-5p expression
