Project description:The human adrenal glands are highly dynamic endocrine organs that are involved in the secretion of various hormones such as steroids and catecholamines. Here we present a single-nuclei and spatial transcriptomic analysis of healthy adult human adrenal glands to provide a complete adrenal gland atlas. With this, we show how such an atlas can be taken advantage when studying adrenocortical diseases, such as adrenocortical adenomas (ACA). Using nornal adrenal as reference, we showed a high intra-tumoural heterogeneity in the single-nuclei transcriptome of ACA, revealing the presence of specific cell populations associated with cortisol secretion and genetic background.

Project description:Aldosterone-producing adenomas (APA) are heterogeneous. The objectives of this study were to compare the transcriptional profiles in APA and normal adjacent adrenal gland (AAG). This was done through the Illumina beadchip analysis of RNA from eight paired APA-AAG. Other tissues (phaeochromocytoma, cushing, and hyperplastic adrenals) were included as controls.

Project description:To determine miRNA profiles in rat adrenals from animals treated with vehicle, ACTH, 17M-NM-1-ethinyl estradiol (17M-NM-1-E2) or dexamethasone (DEX). miRNA expression profiling was performed using AffymetrixM-BM-. GeneChipM-BM-. miRNA 2.0 Arrays. Together with qRT-PCR, several adrenal miRNAs have been identified, whose expression is subject to regulation by one or more than one hormone. RNA was extracted from four group rat adrenal gland and miRNA profiles were established using microarray using AffymetrixM-BM-. GeneChipM-BM-. miRNA 2.0 Arrays and confirmed with qRT-PCR. The microarray data were analyzed using PartekM-BM-. Genome Suite software, version 6.3 CopyrightM-BM-) 2008 (Partek Inc., St. Louis, MO, USA) to comprehensively evaluate the differential expression level of the various samples.

Project description:<p><i>Summary</i></p> <p>The purpose of this study is to perform the first long-term follow up study both of adolescents and young adults with a history of prenatal treatment with dexamethasone and of their mothers and to test for adverse medical or behavioral side effects. The emphasis will be on the outcome of this prenatal treatment in those fetuses who are not affected with steroid 21-hydroxylase deficiency (21OHD) form of congenital adrenal hyperplasia (CAH) and are either heterozygotes or homozygote-unaffected.</p> <p>Prenatal treatment of 46,XX fetuses with 21OHD (via administration of dexamethasone to the pregnant mother) has been shown to reduce the masculinization of the genitalia and, thereby, the later need for 'corrective' feminizing genital surgery and potential impairment of sexual functioning. Along with the suppression of excess prenatal androgen production and reduction of prenatal masculinization of the genitalia in 46,XX fetuses with 21OHD, prenatal dexamethasone treatment may reduce the behavioral masculinization that is well documented in untreated 46, XX patients with 21OHD. Those fetuses who are partially treated until diagnosis of an unaffected status (heterozygous or homozygous-unaffected) will be studied as well. This latter group is of importance because these fetuses are being unnecessarily treated, but we have no way of diagnosing the unaffected status before the 8th week of gestation when treatment must begin for the female fetus who is affected. As treatment is necessary only until term in the female fetus affected with classical CAH, male fetuses and unaffected or heterozygous female fetuses do not require treatment. Thus, only one out of eight fetuses will require prenatal treatment until term. Findings of adverse effects of glucocorticoid treatment in non-human mammals [1, 2] have raised concerns among other clinicians and investigators about potential adverse side effects of such treatment on the developing human. Thus, this study will address this concern and investigate the potential adverse side effects of prenatal treatment.</p> <p><i>Detailed Description </i></p> <p>Females with classical CAH owing to 21-hydroxylase deficiency are born with ambiguous genitalia due to the production of excess androgens in utero. Prenatal treatment with dexamethasone was inaugurated in 1978 by Maguelone Forest and has been the standard of practice in the United States since 1986. Dexamethasone, which crosses the placental barrier, suppresses the fetal adrenal gland production of androgens, thus preventing ambiguous genitalia in the affected female. Children of both sexes are prenatally treated as soon as pregnancies at risk are confirmed. Treatment in females with 21OHD continues to term, but is discontinued in males and unaffected females. To date, 685 pregnancies have been diagnosed, of which 366 fetuses were treated. These investigators will study prenatally treated adolescents and adults 12 years and older with respect to medical and behavioral outcomes (see Table 5). In addition, mothers of children prenatally treated for varying periods of time for suspected 21OHD will be studied for long-term side effects of dexamethasone treatment administered during pregnancy. The long-term outcome in these children and their mothers has never before been studied.</p>

Project description:Despite the ubiquitous function of macrophages across the body, the diversity, origin, and function of adrenal gland macrophages remain largely unknown. We defined the heterogeneity of adrenal gland immune cells using single-cell RNA sequencing and used genetic models to explore the developmental mechanisms yielding to macrophage diversity. We defined populations of monocyte-derived and embryonically seeded adrenal gland macrophages and identified a female-specific subset with low MHC-II expression. In adulthood, monocyte recruitment dominated adrenal gland macrophage maintenance in female mice, while self-proliferation was more important in males. Adrenal gland macrophage sub-tissular distribution followed a sex-dimorphic pattern, with MHC-IIlow macrophages located at the border between the cortex and the medulla. Macrophage sex dimorphism depended on the presence of the cortical Xzone. Forcing X-zone maintenance in males, or its degradation in females, directly impacted the presence of MHC-IIlow macrophages. Adrenal gland macrophage depletion resulted in altered tissue homeostasis, modulated lipid- metabolism and decreased local aldosterone production during stress exposure. Overall, these data explain the heterogeneity of adrenal gland macrophages and point toward sexrestricted distribution and functions of these cells.

Project description:The extracellular matrix (ECM) comprises macromolecules that shape a complex three-dimensional network. Filling the intercellular space and playing a crucial role in the structure and function of tissues, ECM regulates essential cellular processes such as adhesion, differentiation, and cell signaling. In the human adrenal gland, composed of cortex and medulla surrounded by a capsule, the ECM has not yet been directly described, although its impact on the processes of proliferation and steroidogenesis of the adrenal cortex is recognized. This study proposes a comprehensive analysis aims to comprehensively analyze the ECM of the adult human adrenal cortex, which is separated into outer fraction (OF) and inner fraction (IF), by comparing their proteomic profiles. The study discusses the composition, spatial distribution, and relevance of differentially expressed ECM signatures of the adrenal cortex matrisome on adrenal structure and function. The findings were validated through database analysis (cross-validation), histochemical, and immunohistochemical approaches. A total of 121 ECM proteins were identified and categorized into glycoproteins, collagens, ECM regulators, proteoglycans, ECM-affiliated proteins, and secreted factors. Thirty-one ECM proteins were identified only in OF, 9 only in IF, and 81 were identified in common with both fractions. Additionally, 106 ECM proteins were cross-validated using Human matrisome DB 2.0 and the proteins differentially expressed in OF and IF, were identified. This study provides significant insights into the composition and regulation of the ECM in the human adrenal cortex, shedding light on the adrenal microenvironment and its role in the functioning, maintenance, and renewal of the adrenal gland.
