Follicle-Stimulating Hormone Receptors in Oocytes?

Ectopic expression of follicle-stimulating hormone receptors in thyroid tumors

INTRODUCTION In normal conditions follicle-stimulating hormone receptors (FSHR) are expressed in the ovary and the testis. They can also be expressed in gonadal tumors. However, recently we have found FSHR immunostaining in pituitary adenomas, adrenal tumors and neuroendocrine tumors (carcinoids). The aim of this study was to determine whether the same occurs in thyroid tumors. MATERIAL AND M...

Novel C1- Currents Elicited by Follicle Stimulating Hormone and Acetylcholine in Follicle-enclosed Xenopus Oocytes

Voltage-clamp techniques were used to study the membrane currents elicited by follicle stimulating hormone (FSH) and acetylcholine (ACh) in follicleenclosed oocytes of Xenopus laevis (follides). Both agonists caused complex responses that were more evident when the follicles were in hypotonic Ringer solution (HR; 190.4 mosM). In this medium, currents activated by FSH regularly showed three phas...

Follicle-stimulating hormone receptors: a new immunohistochemical marker in cancers?

PURPOSE Follicle-stimulating hormone receptors (FSHR) have been reported in ovarian cancer and prostate cancer cells, but recent studies have highlighted their presence in the endothelium of blood vessels belonging to multiple neoplasias. Current research attempts to determine the role of FSHR in neoplastic proliferation and possible therapeutic or diagnostic implications. This paper aimed to a...
