Increased expression of programmed death ligand 1 (PD-L1) in human pituitary tumors [PDF]

open access: yes, 2016
PURPOSE: Subsets of pituitary tumors exhibit an aggressive clinical courses and recur despite surgery, radiation, and chemotherapy. Because modulation of the immune response through inhibition of T-cell checkpoints has led to durable clinical responses ...

The role of stereotactic radiosurgery in the multimodal management of growth hormone–secreting pituitary adenomas [PDF]

open access: yes, 2010
Growth hormone (GH)–secreting pituitary adenomas represent a common source of GH excess in patients with acromegaly. Whereas surgical extirpation of the culprit lesion is considered first-line treatment, as many as 19% of patients develop recurrent ...

Pituitary Tumors [PDF]

open access: yesEndocrinology and Metabolism Clinics of North America, 2015
Pituitary tumors are commonly encountered intracranial neoplasms that are invariably benign. Classic oncogene mutations are not encountered in these tumors, and disrupted cell cycle control and growth factor signaling likely contribute to pathogenesis and natural history.

Vascular endothelial growth factor production and regulation in rodent and human pituitary tumor cells in vitro [PDF]

open access: yes, 2001
Angiogenesis, the formation of a new blood supply, is an essential step in tumorigenesis. Although vascular endothelial growth factor (VEGF) is known to be a very potent angiogenic factor in most solid tumors, little is known about its production and ...
