Diagnosis of pituitary gonadotroph adenomas in reproductive-aged women.
OBJECTIVE To describe the clinical symptoms associated with the diagnosis of pituitary gonadotroph adenoma in premenopausal women. DESIGN Report of three separate cases. SETTING University medical center. PATIENT(S) Three patients: a 31-year-old woman with primary infertility, recurrent adnexal masses, and highly elevated estradiol level; a 30-year-old woman with recurrent multicystic ova...
متن کاملBioinformatic analysis of gene expression profiles of pituitary gonadotroph adenomas
The aim of the present study was to identify genes, microRNAs (miRNAs/miRs) or pathways associated with the development of pituitary gonadotroph adenomas. The array data of GSE23207, which included 16 samples of multiple endocrine neoplasia-associated rat pituitary homozygous mutations and 5 pituitary tissue samples from healthy rats, were downloaded from the Gene Expression Omnibus database. D...
متن کاملAbsence of activating mutations in the GnRH receptor gene in human pituitary gonadotroph adenomas.
The monoclonal origin of gonadotropin-secreting pituitary adenomas has been well demonstrated but only few molecular abnormalities have so far been recognized in these tumors. For many years, several authors have suggested a role for GnRH and/or GnRH receptors (GnRH-R) in the development of these pituitary adenomas. To test the hypothesis that mutant genes encoding a constitutively activated Gn...
متن کاملSSTR3 is a putative target for the medical treatment of gonadotroph adenomas of the pituitary.
Gonadotroph pituitary adenomas (GPAs) often present as invasive macroadenomas not amenable to complete surgical resection. Radiotherapy is the only post-operative option for patients with large invasive or recurrent lesions. No medical treatment is available for these patients. The somatostatin analogs (SSAs) octreotide and lanreotide that preferentially target somatostatin receptor type 2 (SST...
متن کاملLineage-Specific Restraint of Pituitary Gonadotroph Cell Adenoma Growth
Although pituitary adenomas are usually benign, unique trophic mechanisms restraining cell proliferation are unclear. As GH-secreting adenomas are associated with p53/p21-dependent senescence, we tested mechanisms constraining non-functioning pituitary adenoma growth. Thirty six gonadotroph-derived non-functioning pituitary adenomas all exhibited DNA damage, but undetectable p21 expression. How...
