2DGE-based comparative proteomics was used to analyze proteome variations from controls (n = 8; 3 to 5 gel images per sample) versus each NFPA type, including NF- (n = 3; 3 gel images per sample), LH- (n = 3; 3 gel images per sample), FSH- (n = 3; 3 gel images per sample), and LH/FSH- (n = 3; 3 gel images per sample) adenoma tissues. Here, BRD2 is linked to adenoma.
