ACTH-independent macronodular adrenocortical hyperplasia (AIMAH)

ABSTRACT: ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a clinically and genetically heterogeneous disorder that can be associated with aberrant hormone receptors. Whole-genome expression profiling was analyzed in samples of different nodules from a patient with AIMAH. Total RNA obtained from adrenal nodules were compared to those samples obtained normal adrenal pools

Activation of cyclic AMP signaling leads to different pathway alterations in lesions of the adrenal cortex caused by germline PRKAR1A defects versus those due to somatic GNAS mutations

Project description:PRKAR1A inactivating mutations are responsible for primary pigmented nodular adrenocortical disease (PPNAD) whereas somatic GNAS activating mutations cause macronodular disease in the context of McCune-Albright syndrome (MAS), ACTH-independent hyperplasia (AIMAH) and, rarely, cortisol-producing adenomas (CPA). The whole-genome expression profile (WGEP) of normal (pooled) adrenals, PRKAR1A- (3) and GNAS-mutant (3) was studied. Total RNA obtained from adrenal tumors were compared to those samples obtained from normal adrenal pools

Affymetrix SNP6 array data for ACTH-Independent Macronodular Adrenal Hyperplasia (AIMAH) samples

Project description:AIMAH is an ACTH-independent bilateral enlargement of the adrenal cortex occuring during adulthood. The enlargment is related to the growth of multiple benign nodules. This condition is associated with various degrees of cortisol hypersecretion. The occurence of several nodules in both adrenals, and the existence of familial forms, suggest the existence of a germline genetic predisposition. To find the gene(s), the aim of the project was to look for recurrent chromosomal alterations in the AIMAH nodules. Extensive mapping of somatic gains, losses and copy-neutral loss of heterozygosity (LOH) was performed with Affymetrix SNP6 arrays. A copy neutral LOH of 16p, occuring in 7 of 26 patients, was one of the only recurrent alterations, pointing towards a candidate gene in this region. Of note this condition differs from the congenital adrenal hyperplasias, related to genetic alterations of steroidogenesis (the latter is an ACTH dependent adrenal hyperplasia). Affymetrix SNP6 arrays were performed according to the manufacturer's directions on DNA extracted from cryopreserved tumor samples or peripheral blood samples. Copy number and LOH analysis of Affymetrix SNP6 arrays was performed for AIMAH nodules from 26 patients, including 18 with paired leucocyte and nodules (1 to 4 nodules per patient), and 8 with a single nodule (no paired leucocyte available)

Genome-wide analysis of adult adrenocortical cells gene expression after 48 h ACTH treatment

Project description:Analysis of ACTH-regulation on adrenocortical cells at gene expression level. The hypothesis tested in the present study was that ACTH increases chronic cell growth and steroidogenesis in adrenal glands by changing the gene expression profile. Results provide important information of the response of adrenocortical cells gene expression to chronic ACTH treatment. Total RNA obtained from primary cultured adult adrenal cells subjected to 48 hours in vitro treatment of ACTH compared to untreated control cell.

Alternate protein kinase A activity identifies a unique population of stromal cells in adult bone

Project description:We investigated the Prkar1a+/- mice when bred with Prkaca+/- genetic backgrounds. Prkar1a+/-Prkaca+/- mice not only continued to develop bone lesions but also demonstrated a significant increase in both the number and the severity of the lesions, as well as a reduction in the age of first appearance of any bone abnormality. Histological analysis of bone from Prkar1a+/-Prkaca+/- mice showed that lesions had similarity to tumors from humans with CNC and some resemblance (but also differences) from humans and mice with fibrous dysplasia (FD). Prkar1a+/- and Prkar1a+/-Prkaca+/- mouse lesions always involved a particular sub-population of cells that could be identified as belonging to the osteoblastic lineage, that were initially located on the endosteal surface of the periosteum and nearby trabecular bone proximal to the growth plate of the long bones and vertebrae, and resembled bone stromal cells (BSCs). The bone lesions expressed high level of mesenchymal proteins like n-cadherin, vimentin, snail1, twist1, mmp2 and mmp9 when compared to WT bone. On top of this, bone lesions from Prkar1a+/-Prkaca+/- mice also showed an increased expression of keratin related genes, which are involved in hair follicle and epithelial differentiation, when compared to lesions from Prkar1a+/- mice. Total RNA obtained from bone lesions from Prkar1a+/- and Prkar1a+/-Prkaca+/- mice were compared to those obtained from WT and Prkaca+/- mice.

DH06 Adrenal ACTH Sus scrofa

Project description:Large White and Meishan pigs were either non-treated or injected with mammalian 1-24 ACTH (Immediate Synachten, Novartis France) at the dose of 250 µg per animal. Pigs were sacrificed either immediately after capture from their home cage (non-treated animals) or 1 hour following ACTH injection. Adrenal glands were immediately collected from pigs and frozen on dry ice and then stored at -80°C until RNA isolation. Keywords: stress response, adrenal, gene expression, pig
