Disruption of the normal cell cycle is one of the most frequent alterations in tumour cells, contributing to uncontrolled cell proliferation during tumour development. The CDK inhibitor p27 plays a pivotal role in controlling cell proliferation during development and tumourigenesis, and has been implicated in tumorigenesis in rats. Previous studies have demonstrated changes in p27 protein expression, in human pituitary tumours,especially in corticotroph tumours, where p27 prot...

MIF (Macrophage Migration Inhibitory Factor) is over-expressed in the nucleus of pituitary adenoma cells

MIF can override the anti-inflammatory actions of glucocorticoids during immune response, and thus is an important pro-inflammatory factor. The presence of MIF in the cytoplasm of adenomatous cells of the anterior pituitary has been described, and high levels of MIF in other rapidly-proliferating tissues have been demonstrated. It is hypothesized that MIF release from these cells is influenced by the hypothalamo-pituitary-adrenal axis, and that ACTH and MIF are released simult...
