MGMT, Ki-67, and p53 protein immunohistochemistry. A prolactinoma tissue demonstrates weak (a) and strong (b) nuclear staining of MGMT. The endothelial cell (arrow) acts as an internal positive control (original magnification 400×). Negative (c) and positive (d) staining of Ki-67, and negative (e) and positive (f) staining of p53 protein are shown in prolactinoma specimens (original magnification 400×)
