We explored the role of disordered pituitary cell proliferation control in the pathogenesis of these invariably benign adenomas, studying the mechanisms underlying pituitary aneuploidy, premature proliferative arrest (senescence), markers of cell proliferation and tumorigenesis in single, double or triply mutant transgenic mice with mutations of Rb, Pttg and/or p21.
