Treatment of clinically nonfunctioning pituitary adenomas with dopamine agonists.
OBJECTIVE Clinically nonfunctioning pituitary adenoma (NFPA) remains the only pituitary tumor subtype for which no effective medical therapy is available or recommended. We evaluated dopamine agonist (DA) therapy for preventing growth of postsurgical pituitary tumor remnants. DESIGN The study design included historical cohort analysis of clinical results at two pituitary referral centers with...
متن کاملHeterogeneous dopamine D2 receptor subtype messenger ribonucleic acid expression in clinically nonfunctioning pituitary adenomas.
Little is known about differences in the expression, localization, and function of the two dopamine D2 receptor subtypes, D2short and D2long (D2s and D2l), in either normal or adenomatous pituitary. We investigated the messenger RNA (mRNA) expression of the D2 receptor (D2R) subtypes in clinically nonfunctioning pituitary adenomas by in situ hybridization using subtype-specific oligonucleotides...

15 صفحه اولNonfunctioning giant pituitary adenomas: Invasiveness and recurrence
BACKGROUND We report our surgical series of 35 patients with giant nonfunctioning pituitary adenomas (GNFPA). We analyzed the rule of Ki-67 antigen expression in predicting recurrence. METHODS Thirty-five patients were operated between 2000 and 2010. Suprassellar extension of the tumors were classified according to Hardy and Mohr based on magnetic resonance (MR) studies. Pituitary endocrine f...
متن کاملMethylation Status of H19/IGF2 Differentially Methylated Region in in vitro Human Blastocysts Donated by Healthy Couples
Backgrund: Imprinted genes are a unique subset of few genes, which have been differentially methylated region (DMR) in a parental origin-dependent manner during gametogenesis, and these genes are highly protected during pre-implantation epigenetic reprogramming. Several studies heve shown that the particular vulnerability of imprinting genes during suboptimal pre- and peri-conception microenvir...
