An organoid model of the human adrenal cortex identifies drivers of steroidogenesis and zonation [scRNA-seq]

ABSTRACT: The adrenal cortex is the main source of steroid hormones including aldosterone, cortisol and androgens. These hormones play a crucial part in maintaining blood pressure, regulating metabolism and sexual development, respectively. The growth factors and transcriptional networks governing adrenal zonation remain poorly understood. Here, we established organoids derived from primary developing human adrenal cortex tissue. These tissue-resident stem cell-derived organoids display longevity and are composed of mature cells producing different steroid hormones. We use spatial transcriptomics to identify zonated growth factors in tissue, and explore the role of 42 different molecules in controlling cell identity and steroidogenesis using organoids. We find that a combination of WNT, cAMP, BMP/TGFβ and nuclear receptors can regulate cell states representing the different cortical zones. Together, human adrenal cortex organoids represent a complex cellular model to study adrenal biology and disease.

Reconstitution of human adrenocortical specification and steroidogenesis using induced pluripotent stem cells [scRNA-seq]

Project description:The adrenal cortex produces vital steroid hormones that maintain homeostasis. While steroid hormones produced from the fetal zone adrenal cortex are essential for both fetal development and maintenance of pregnancy, the molecular mechanisms leading to human adrenal cortex development and steroid synthesis remain poorly understood due to the paucity of model systems. Through progressive generation of fetal zone adrenal cortex-like cells (FZLCs) from human induced pluripotent stem cells through posterior intermediate mesoderm-like, adrenogenic coelomic epithelium and adrenal primordium-like states, we provide the first in vitro reconstitution of human adrenocortical fetal specification. Generation of FZLCs faithfully recapitulates human embryonic adrenal cortex specification as evidenced by histomorphological and ultrastructural analysis, transcriptional profiles and delta-5 steroid biosynthesis and occurs in an adrenocorticotropic hormone (ACTH)-independent manner, consistent with clinical observations. Furthermore, we demonstrate that FZLC generation is promoted by SHH and inhibited by NOTCH, ACTIVIN and WNT signaling and that steroid synthesis is amplified by ACTH/PKA signaling and blocked by pharmacologic inhibitors of delta 5 steroid synthesis enzymes. Finally, NR5A1 appear to self-stabilize its promoter activity and promote FZLC survival and steroidogenesis. Together, these findings provide a framework for understanding and reconstituting human adrenocortical development in vitro and pave the way for future cell-based therapies of adrenal insufficiency.

A spatiotemporal regulatory network for steroidogenesis of human fetal adrenal glands and gonads

Project description:Human fetal adrenal glands are huge endocrine organ, produce prodigious quantities of dehydroepiandrosterone and its sulfate (DHEA/DHEAS), which is the most prominent precursor for steroid hormones, adrenal gonads dysfunction leads to states of virilization or effemination. However, for a long time the function of fetal adrenal in initial sex differentiation is unclear. Herein, we draw out a single-cell transcriptional landscape of human fetal adrenals and gonad from 6 to 14 gestational weeks (GW). We found that the adrenal glands begin to express CYP17A1 steroid-related enzyme much early than testis, subsequent testis steroid express pattern support de novo or halfway testosterone synthesis. Excepted steroidogenic cell, notably, the immune cells or neurocyte shows steroid metabolism or regulation ability, such as CD5L+ macrophage interacted with steroidogenic cell and SRD5A1+ AKR1C2+ chromaffin cells synthesis active testosterone DHT through backdoor pathway. Sex different were found at adrenal glands and gonad development: there is a small HSD3B2 peak occurs only in female adrenal glands around 10-12 GW within the time window of sex differentiation. SST expression levels or SST+ cells quantity in adrenal glands and gonads are different in two gender. Our research indicates that a sex different in spatial and temporal disparities steroidogenic regulatory networks in adrenal glands and gonads, facilitating further exploration of development and physiology of human adrenal glands.

HIF-1α CUT&Tag binding profile reveals a multifaceted regulation of steroidogenesis

Project description:The production of steroid hormones by the adrenal cortex is essential for maintaining homeostasis in response to stress. Disruptions to this process have been linked to various diseases, including congenital defects in steroid synthesis, Cushing syndrome, and adrenal tumors. Therefore, proper regulation of steroid hormone levels is essential for maintaining physiological balance and overall health. Hypoxia is a key regulator of adrenal steroidogenesis acting via the stabilization of HIF-1α transcription factors. We recently identified HIF-1α as a regulator of adrenal steroidogenesis through its control of specific microRNAs (miRNAs) that target key steroidogenic enzymes. However, the mechanisms by which HIF-1α influences miRNA expression remain unclear. To address this, we used the Cleavage Under Targets & Tagmentation (CUT&Tag) technique to map HIF-1α binding sites across the genome in a murine adrenocortical cell line. Our analysis of the HIF-1α binding profile revealed putative binding sites not only in classic steroidogenic gene loci, including Cyp11a1, but also in miRNA loci involved in steroid regulation. Crucially, HIF-1α-bound regions included genes involved in miRNA biogenesis and function, such as nuclear microprocessor and cytoplasmic RNA-induced silencing complex (RISC) components. Subsequent analysis of hypoxic transcriptomic profiles demonstrated widespread repression of these miRNA biogenesis and function genes by hypoxia, that could be modulated by HIF-1α. Based on our previous identification of HIF-1α as a regulator of adrenal steroidogenesis, our current findings further support its dual role in directly controlling steroidogenic gene expression via both transcriptional and posttranscriptional mechanisms. These results reinforce the HIF pathway as a master regulator of steroid hormone output under hypoxic conditions.

HIF1α is an essential regulator of steroidogenesis in the adrenal gland

Project description:Hormones produced by the adrenal cortex are absolutely essential for numerous processes in living animals. Our research group investigated to what extend the central regulators of deprived oxygen, hypoxia inducible factors (HIFs), contribute to this steroidogenesis. For this, we developed a set of new transgenic mouse lines displaying modified HIF1α and HIF2α levels in cortical cells and revealed that HIF1α exclusively regulates the transcription of a majority of enzymes responsible for the production of glucocorticoids and mineralocorticoids as well as a consequent inflection of cytokines in circulation. These novel tools will be helpful to understand how sustained and chronic changes in adrenocortical hormones can impact during health and disease.

In vivo verification of the pathophysiology of lipoid congenital adrenal hyperplasia in the adrenal cortex

Project description:Our study showed that the steroidogenic capacity firstly decreased without tissue change (the first hit) and secondarily declined with tissue change (the second hit) in the adrenal cortex of lipoid congenital adrenal hyperplasia. The key feature of the secondary decline of steroidogenic capacity might be the decreased gene expression related to steroid biosynthesis following the lipid accumulation exacerbated by ACTH hypersecretion.

Compound-induced NR5A1 exon-skipping and circular-RNA expression show impaired steroidogenesis in adrenocortical cancer cells

Project description:Despite the intensive search for an effective drug to treat steroid-producing adrenocortical carcinomas, there are few therapeutic options. We sought whether splicing modifying compounds are effective on this devastating disease. Here, we show that a chemical compound in clinical trial, CX-4945, suppressed the expression of NR5A1 through aberrant multiple exon skipping leading to suppressed steroidogenesis and induced dysfunctional autophagy and progression to ER-stress-related apoptosis. A circular RNA of NR5A1 exons with an IRE1α-cleavage site on the ligated ends (circAd4BP HAC1-type ex1-6 RNA) is expressed in normal adrenal cortex but not in H295R adrenocortical cancer cells, and CX-4945 induced a different circular RNA of NR5A1 exons (circAd4BP ex2-4 RNA). This potential pharmacological control of abnormal steroidogenesis through NR5A1 aberrant splicing and interplay with its circAd4BP makes CX-4945 a strong candidate novel drug for the treatment of adrenocortical carcinomas.

Adrenal Abcg1 controls cholesterol flux and steroidogenesis

Project description:Cholesterol is the precursor of all steroids, but how cholesterol flux is controlled in steroidogenic tissues is poorly understood. The cholesterol exporter ABCG1 is an essential component of the reverse cholesterol pathway and its systemic inactivation results in neutral lipid redistribution to macrophages. However, the function of ABCG1 in steroidogenic organs is not explored. To model this question, we inactivated the ortholog Abcg1 gene in the mouse adrenal cortex. Abcg1 disruption led to an adrenal-specific increase in transcripts involved in cholesterol uptake and de novo synthesis, and to an 80% increase in corticosterone production. Importantly, this phenotype was not recapitulated by inactivation of the cholesterol exporter Abca1. The absence of any change in lipid profile suggested that adrenal Abcg1 is not involved in cholesterol export to a clinically relevant extent.
