CYP11A1 and pituitary gland adenoma: Among the genes overexpressed in the rat pituitary adenomas, predicted to be up-regulated in at least 2 of the 3 human expression array studies by data mining (Supplementary Table 2, in bold), and never before associated with pituitary adenomas, are Cyp11a1 and Nusap1. Thus, these two genes were selected for further analyses.
