Project description:By comparing the transcriptome of TART with fetal- and adult- testis and adrenal tissues, this study aimed to unravel the origin of TART. Sixteen TART samples were previously obtained from patients with CAH (n=7) or recurrent Cushing’s Disease (n=1). Adult adrenal (n=11), adult testis (n=10), fetal adrenal (n=13), and fetal testis (n=5) tissues were obtained.

Project description:BackgroundTesticular adrenal rest tumors (TART) are a common complication of unknown cellular origin in patients with congenital adrenal hyperplasia (CAH). These benign tumors have both adrenal and testicular characteristics and are hypothesized to either derive from cells of adrenal origin from the fetal adrenogonadal primordium or by atypical differentiation of adult Leydig-progenitor cells.ObjectiveThis study aims to unravel the identity and etiology of TART.MethodsCo-expression of adrenal-specific CYP11B1 and Leydig cell-specific HSD17B3 in TART was studied using immunohistochemistry. We studied the possibility of TART being derived from atypical differentiation of adult Leydig-progenitor cells by the quantification of adrenal-specific enzyme expression upon adrenocorticotrophic hormone (ACTH)-like stimulation of ex vivo cultured platelet-derived growth factor receptor alpha-positive cells. By comparing the transcriptome of TART (n = 16) with the transcriptome of fetal adrenal (n = 13), fetal testis (n = 5), adult adrenal (n = 11), and adult testis (n = 10) tissues, we explored the identity of TART.ResultsWe demonstrate co-expression of adrenal-specific CYP11B1 and testis-specific HSD17B3 in TART cells, indicating the existence of a distinct TART cell exhibiting both adrenal and testicular characteristics. Ex vivo cultured adult Leydig-progenitor cells did not express the ACTH-receptor MC2R but did express CYP11B1 upon stimulation. Unsupervised clustering of transcriptome data showed that TART was most similar to adult adrenal tissue, followed by adult testis tissue, and least similar to either fetal tissue.ConclusionOur data suggest that TART is induced - most likely via activation of a cAMP/protein kinase A-dependent receptor - from a progenitor cell into a unique mature adrenal-like cell type, sometimes exhibiting both adrenal and testicular features.

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.

Project description:Testicular adrenal rest tumours (TARTs) are benign adrenal-like testicular tumours that frequently occur in male patients with congenital adrenal hyperplasia. Recently, GATA transcription factors have been linked to the development of TARTs in mice. The aim of our study was to determine GATA expression in human TARTs and other steroidogenic tissues. We determined GATA expression in TARTs (n?=?16), Leydig cell tumours (LCTs; n?=?7), adrenal (foetal (n?=?6)?+?adult (n?=?10)) and testis (foetal (n?=?13)?+?adult (n?=?8)). We found testis-like GATA4, and adrenal-like GATA3 and GATA6 gene expressions by qPCR in human TARTs, indicating mixed testicular and adrenal characteristics of TARTs. Currently, no marker is available to discriminate TARTs from LCTs, leading to misdiagnosis and incorrect treatment. GATA3 and GATA6 mRNAs exhibited excellent discriminative power (area under the curve of 0.908 and 0.816, respectively), while immunohistochemistry did not. GATA genes contain several CREB-binding sites and incubation with 0.1?mM dibutyryl cAMP for 4?h stimulated GATA3, GATA4 and GATA6 expressions in a human foetal testis cell line (hs181.tes). Incubation of adrenocortical cells (H295RA) with ACTH, however, did not induce GATA expression in vitro Although ACTH did not dysregulate GATA expression in the only human ACTH-sensitive in vitro model available, our results do suggest that aberrant expression of GATA transcription factors in human TARTs might be involved in TART formation.

Project description:ContextTesticular adrenal rest tumors (TART) are a common complication in males with classic 21-hydroxylase deficiency (21OHD). TART are likely to contribute to the androgen excess in 21OHD patients, but a direct quantification of steroidogenesis from these tumors has not been yet done.ObjectiveWe aimed to define the production of 11-oxygenated 19-carbon (11oxC19) steroids by TART.MethodsUsing liquid chromatography-tandem mass spectrometry, steroids were measured in left (n = 7) and right (n = 4) spermatic vein and simultaneously drawn peripheral blood (n = 7) samples from 7 men with 21OHD and TART. For comparison, we also measured the peripheral steroid concentrations in 5 adrenalectomized patients and 12 age- and BMI-matched controls. Additionally, steroids were quantified in TART cell- and adrenal cell-conditioned medium, with and without adrenocorticotropic hormone (ACTH) stimulation.ResultsCompared with peripheral blood from 21OHD patients with TART, the spermatic vein samples displayed the highest gradient for 11β-hydroxytestosterone (11OHT; 96-fold) of the 11oxC19 steroids, followed by 11-ketotestosterone (47-fold) and 11β-hydroxyandrostenedione (11OHA4; 29-fold), suggesting production of these steroids in TART. TART cells produced higher levels of testosterone and lower levels of A4 and 11OHA4 after ACTH stimulation compared with adrenal cells, indicating ACTH-induced production of testosterone in TART.ConclusionIn patients with 21OHD, TART produce 11oxC19 steroids, but in different proportions than the adrenals. The very high ratio of 11OHT in spermatic vs peripheral vein blood suggests the 11-hydroxylation of testosterone by TART, and the in vitro results indicate that this metabolism is ACTH-sensitive.

Project description:Transcription factor GATA6 is expressed in the fetal and adult adrenal cortex and has been implicated in steroidogenesis. To characterize the role of GATA6 in adrenocortical development and function, we generated mice in which Gata6 was conditionally deleted using Cre-LoxP recombination with Sf1-cre. The adrenal glands of adult Gata6 conditional knockout (cKO) mice were small and had a thin cortex with thickened capsule. Cytomegalic changes were evident in the adrenal glands of fetal and adult cKO mice, and chromaffin cells were ectopically located at the periphery of the glands. The secretion of corticosterone in response to exogenous ACTH was blunted in cKO mice. Cells expressing gonadal-like markers, including Gata4, Amhr2, and Tcf21, accumulated in the adrenal capsule and subcapsule of cKO mice, suggesting aberrant adrenocortical progenitor/stem cell differentiation. Gonadectomy triggered the overexpression of sex steroidogenic differentiation markers, such as Lhcgr and Cyp17, in the adrenal glands of male and female cKO mice. Nulliparous female and orchiectomized male cKO mice lacked an adrenal X-zone. Microarray hybridization identified Pik3c2g as a novel X-zone marker that is downregulated in the adrenal glands of nulliparous female Gata6 cKO mice. Our findings offer genetic proof of the longstanding hypothesis that GATA6 regulates the differentiation of steroidogenic progenitors into corticoid-producing cells. 3 replicates from both conditional knockout of Gata6 in the adrenal gland and control adrenal glands from non-knockout mice were compared

Project description:ContextPatients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes.ObjectiveTo identify biomarkers of disease control and long-term complications in 21OHD.Setting and participantsCross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center.MethodsWe correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones.ResultsTotal adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11β-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001).Conclusion11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.
