Calcitriol-Mediated Hypercalcemia, Somatostatin Receptors Expression and 25-Hydroxyvitamin D3-1α- Hydroxylase in GIST Tumors [PDF]

Frontiers in Endocrinology, 2022
Hypercalcemia is a common complication in cancer patients Mainly caused by Parathyroid hormone-related protein (PTHrP) secretion and metastasis. Calcitriol secretion is a rare source of hypercalcemia in solid tumors, especially in gastrointestinal ...

Cryo-EM structure of the human somatostatin receptor 2 complex with its agonist somatostatin delineates the ligand-binding specificity

eLife, 2022
Somatostatin is a peptide hormone that regulates endocrine systems by binding to G-protein-coupled somatostatin receptors. Somatostatin receptor 2 (SSTR2) is a human somatostatin receptor and is highly implicated in hormone disorders, cancers, and ...

Molecular targets in acromegaly

Frontiers in Endocrinology, 2022
Molecular therapeutic targets in growth hormone (GH)-secreting adenomas range from well-characterized surface receptors that recognize approved drugs, to surface and intracellular markers that are potential candidates for new drug development.

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1-5 and Therapeutic Implications in Neuroendocrine and Non-Neuroendocrine Malignancies. [PDF]

Int J Cancer
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Somatostatin and somatostatin receptors in retinal diseases [PDF]

European Journal of Endocrinology, 2000
Somatostatin is a small neuropeptide that is producedin the central nervous system, where it acts as aneurotransmitter. This neuropeptide also has animportant role in the neuroendocrine system as aninhibitor of hormone release, the most strikingexample of which is the inhibition of growth hormonerelease.

Detection of somatostatin receptors in human osteosarcoma

World Journal of Surgical Oncology, 2008
Background The location of osteosarcoma in the metaphysis as well as the age of the patients during the most rapid tumour growth suggest that factors related to skeletal growth are involved in the pathogenesis of this tumour.

Evaluation of the expression of somatostatin receptors by immunohistochemistry in neuroendocrine tumors of the small intestine

Polish Journal of Pathology, 2020
Most neuroendocrine neoplasms (NEN) are characterized by the presence of somatostatin receptors (SSTR) which we use in location diagnostics and treatment.

Somatostatin receptors

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2003
In 1972, Brazeau et al. isolated somatostatin (somatotropin release-inhibiting factor, SRIF), a cyclic polypeptide with two biologically active isoforms (SRIF-14 and SRIF-28). This event prompted the successful quest for SRIF receptors. Then, nearly a quarter of a century later, it was announced that a neuropeptide, to be named cortistatin (CST), had ...

Activation of Muscarinic Acetylcholine Receptor Subtype 4 is Essential for Cholinergic Stimulation of Gastric Acid Secretion - Relation To D Cell/Somatostatin -

Frontiers in Pharmacology, 2016
Background/Aim: Muscarinic acetylcholine receptors exist in five subtypes (M1~M5), and they are widely expressed in various tissues to mediate diverse autonomic functions, including gastric secretion.
