Bioinformatic 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 کاملDifferential expression of menin in sporadic pituitary adenomas.
Pituitary adenomas represent one of the key features of multiple endocrine neoplasia type 1. The gene involved in this syndrome (MEN1) is a putative tumor suppressor, that codes for a 610-amino acid nuclear protein termed 'menin'. Analyses of sporadic pituitary adenomas have so far failed to reveal MEN1 mutations or defects in MEN1 transcription in these tumors. In the present study we detected...
متن کاملDifferential expression of folate receptor in pituitary adenomas.
Pituitary adenomas cause significant morbidity caused by compression of regional structures or the inappropriate expression of pituitary hormones. However, little is known about the molecular changes that contribute to the development of these tumors. To investigate these changes, we recently used cDNA microarray analysis to identify several genes with altered expression patterns in pituitary a...
متن کاملDifferential expression of microRNAs in GH-secreting pituitary adenomas
BACKGROUND The purpose of this study was to (1) identify specific miRNAs in growth hormones (GH)-secreting pituitary adenomas; (2) determine the relationship between the expression of these miRNAs and tumor size, somatostatin analogs treatment, and responsiveness to somatostatin analogs (SSA). METHODS Fifteen GH-secreting adenomas patients were treated with lanreotide for 4 months before surg...
متن کاملGene expression profiling analysis of MENX-associated rat pituitary adenomas contributes to understand molecular mechanisms of human pituitary adenomas
The present study aimed to screen potential genes associated with pituitary adenomas to obtain further understanding with regard to the pathogenesis of pituitary adenomas. The microarray GSE23207 dataset, containing 16 pituitary adenoma samples from multiple endocrine neoplasia syndrome-associated rats and 5 normal pituitary tissue samples, was downloaded from Gene Expression Omnibus. The Linea...
