a Whole miRNA expression profile differentiate pituitary oncocytoma, recurrent oncocytoma and normal tissue. b Significant miRNAs between pituitary oncocytoma, recurrent oncocytoma and normal tissue. c Pituitary oncocytoma and normal pituitary samples were separated by gene expression profile. d Significant differentially expressed genes in pituitary oncocytoma compared to normal tissue (with a fold change cut-off:2 and p < 0.05 after FDR adjustment). N normal pituitary, O spindle cell onocytoma, R recurrent oncocytoma
