Abstract:
The GH secretagogue (GHS) receptor (GHS-R) has been characterized and cloned. It is a member of a family of seven transmembrane receptors and is closely related to the neurotensin and TRH receptors. To determine the expression of this receptor in normal anterior pituitary and in 24 human pituitary adenomas, we analyzed GHS-R messenger ribonucleic acid (mRNA) using a RT-PCR assay. We found that normal human pituitary was positive for the GHS-R signal. In addition, all GH-secreting adenomas and the one TSH-secreting adenoma demonstrated the presence of GHS-R mRNA.

Abstract:
Despite the fact that pituitary adenomas are among the most frequent brain tumours, TSH-secreting pituitary adenomas (thyrotropinomas) are less than 1% of all adenomas. Due to the increase in the free fractions of thyroid hormones at normal or elevated TSH levels, the majority of patients with these pituitary adenomas have a long anamnesis of thyrotoxicosis which requires a differential diagnosis with thyroid pathology (Graves’ disease, toxic adenoma, autonomously functioning thyroid nodules). The diagnosis of the thyrotropinoma is quite challenging for clinicians. This article describes the c

Abstract:
Thyrotoxicosis, which characteristics are increased excitability, emotional lability, tachycardia episodes, increasing of free fractions of tetraiodothyronine (T4) and triiodothyronine (T3) is one of the most common endocrinological syndromes. However, during the interpretation of thyroid status it is very important to take into account the possibility that a patient has TSH-secreting pituitary adenoma. Timely diagnosis of TSH-secreting adenomas plays prominent role in guiding the treatment course since it is associated with an improvement of long-term prognosis and an increase of the patient’

Introduction: TSH-secreting pituitary adenomas (TSH-sPAs) or thyrotropinomas are very rare forms of pituitary adenomas (PAs).

Plurigormonal tumors occur in less than 1% of all pituitary adenomas. The most common form of mixed secretion adenoma in this patient population, derived from the Pit-1 cell line, produces various combinations of hormones: growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH).

Abstract:
ABSTRACT Adenomas can develop from each cell type of the anterior pituitary. In the normal pituitary, three of these cell types, the GH-, prolactin- and TSH-secreting cells, express the transcription factor Pit-1/GHF-1 which is responsible for prolactin and GH (and probably TSH) cell commitment, differentiation, probably proliferation and gene expression. We have analysed the expression of Pit-1/GHF-1 in a panel of human pituitary adenomas. All GH-, prolactin- and TSH-expressing adenomas studied expressed the Pit-1/GHF-1 factor, as demonstrated by in-situ hybridization and immunocytochemistry.

Abstract:
Thyrotoxicosis most often occurs due to autoimmune diseases of the thyroid gland or a multi-nodular toxic goiter, but it can also be caused by TSH-secreting pituitary adenomas. In the presence of these adenomas, the levels of circulating free T3 and T4 increase in the absence of suppression, even with elevated TSH levels. Incorrect interpretation of results from studies that only measure TSH can lead to erroneous diagnoses and management strategies for patients, including unnecessary surgery or radioactive iodine therapy. This can contribute to the growth of pituitary tumors. Various tests hav

Abstract:
Pituitary tumors usually show a particular benign nature, with a slow growth potential. Despite these characteristics, they can cause severe complications due to their excessive hormone secretion. Still, further investigations are needed to understand the molecular mechanisms implicated in their development in detail. AHRR (Aryl Hydrocarbon Receptor (AHR) Repressor) and HSP90 (Heat Shock Protein 90) are good candidates for playing a role in pituitary tumorigenesis due to their tumorigenic role reported in different types of tumors and their action in the metabolism of endocrine disruptors (EDs

Prolactinomas are pituitary adenomas that are prolactin-secreting and can lead to galactorrhea, amenorrhea, and infertility. These symptoms often cause women to present earlier than their male counterparts, who are more likely to develop headaches and visual field deficits. Hyperprolactinemia warrants a thorough workup, which should include pregnancy testing, a thyroid-stimulating hormone level, and a thorough review of the patient’s medications.
