miR21, miR146a, and miR155 expression levels in GG and peritumoral cortex. a Quantitative real-time PCR of miR21, miR146a, and miR155 in GG (n = 26; formalin-fixed, paraffin-embedded, FFPE material) and peritumoral cortex (ctx; n = 15; FFPE material). Data are expressed relative to the levels observed in control ctx (n = 5, FFPE); miRNAs expression was normalized to that of the U6B small nuclear RNA gene (Rnu6B). The error bars represent SEM; statistical significance: *p < 0.05; **p < 0.01. b Schematic representation of miR21, miR146a, and miR155 changes in GG and peritumoral ctx
