AIP and MEN1 mutations and AIP immunohistochemistry in pituitary adenomas in a tertiary referral center. [PDF]

, 2019
Background: Pituitary adenomas have a high disease burden due to tumor growth/ invasion and disordered hormonal secretion. Germline mutations in genes such as MEN1 and AIP are associated with early onset of aggressive pituitary adenomas that can be ...

Mathematical Modelling of Hypothalamus-Pituitary-Adrenal Axis Dynamics: A Review, a Novel Approach, and Future [PDF]

arXiv, 2023
A novel mathematical model for the hypothalamic pituitary adrenal (HPA) axis is proposed to comprehend the oscillations observed in hormone concentration and potential dysfunction within the HPA axis in stressful situation. This model integrates impact of hippocampal receptors on the secretion of corticotropin-releasing hormone (CRH), an additional ...

The pathophysiology of pituitary adenomas

Best Practice & Research Clinical Endocrinology & Metabolism, 2009
The pathogenesis of tumour formation in the anterior pituitary has been intensively studied, but the causative mechanisms involved in pituitary cell transformation and tumourigenesis remain elusive. Most pituitary tumours are sporadic, but some arise as a component of genetic syndromes such as the McCune-Albright syndrome, multiple endocrine neoplasia ...
