Epidemiology of Functioning Pituitary Adenomas [PDF]
Pituitary adenomas (PAs) are defined as benign monoclonal tumors in the pituitary gland that cause symptoms due to either hormonal hypersecretion or a space-occupying effect, and are classified as functioning or non-functioning.

Targeted treatment with somatostatin analogues: widening horizons of clinical practice
Targeted treatment with somatostatin analogues (SA) in acromegaly and neuroendocrine neoplasms may have some benefits compared to curative treatments, because these agents decrease excessive hormone secretion and exert a tumor-suppressive effect ...

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

Sex differences in the pituitary TGFβ1 system: the role of TGFβ1 in prolactinoma development [PDF]
Prolactinomas are the most frequent functioning pituitary adenomas, and sex differences in tumor size, behavior and incidence have been described. These differences have been associated with earlier diagnosis in woman, as well as with serum estradiol ...

Order-of-mutation effects on cancer progression: models for myeloproliferative neoplasm [PDF]
We develop a modeling framework for cancer progression that distinguishes the order of two possible mutations. Recent observations and information on myeloproliferative neoplasms are analyzed within our framework. In some patients with myeloproliferative neoplasms, two genetic mutations can be found, JAK2 V617F and TET2.
