[PMID: 39051498 PMCID: PMC11336057 DOI: 10.1049/syb2.12096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 06/24/2024] [Accepted: 07/04/2024] [Indexed: 07/27/2024] Open
Abstract
EMT dysfunction is a dominant mechanisms of hypospadias. Thus, identification of EMT-related lncRNAs based on transcriptome sequencing data of hypospadias might provide novel molecular markers and therapeutic targets for hypospadias. First, the microarray data related to hypospadias were downloaded from Gene Expression Omnibus (GEO). Besides, the differentially expressed lncRNAs and messenger RNAs (mRNAs) related to EMT were screened to construct lncRNA-mRNA co-expression interaction pairs. In addition, the microRNA (miRNA) prediction analysis was performed through bioinformatics methods to construct a ceRNA network. Moreover, function prediction and function enrichment and pathway analyses were also performed. Finally, the core EMT-related lncRNAs were verified based on mRNA expression changes and cell functions. A total of 6 EMT-related lncRNAs were identified and 123 mRNA-lncRNA co-expression interaction pairs were screened in this study. Additionally, a ceRNA regulatory network comprising 17 mRNAs, 4 lncRNAs, and 28 miRNAs was constructed based on the prediction of hypospadias-related miRNAs. The validation results of the dataset GSE121712 revealed that only BEX1 was positively correlated with the expression of the lncRNA GNAS-AS1 (r = 0.874, P < 0.01), both of which had high expression. The cell experiment results demonstrated that interfering with the expression of GNAS-AS1 significantly promoted the proliferation, migration, and EMT of cells. Importantly, it was confirmed that GNAS-AS1 can serve as a ceRNA and play an important role in the EMT of hypospadias. Hence, it may be considered as a potential target in the treatment of this disease.

Abstract
PURPOSE Urethral hypospadias, a common congenital malformation in males, is closely linked with disruptions in uroepithelial cell (UEC) processes. Evidence exists reporting that urine-derived exosomes (Urine-Exos) enhance UEC proliferation and regeneration, suggesting a potential role in preventing hypospadias. However, the specific influence of Urine-Exos on urethral hypospadias and the molecular mechanisms involved are not fully understood. This study focuses on investigating the capability of Urine-Exos to mitigate urethral hypospadias and aims to uncover the underlying molecular mechanisms. METHODS Bioinformatics analysis was performed to identify key gene targets in Urine-Exos potentially involved in hypospadias. Subsequent in vitro and in vivo experiments were conducted to validate the regulatory effects of Urine-Exos on hypospadias. RESULTS Bioinformatics screening revealed syndecan-1 (SDC1) as a potential pivotal gene for the prevention of hypospadias. In vitro experiments demonstrated that Urine-Exos enhanced the proliferation and migration of UECs by transferring SDC1 and inhibiting cell apoptosis. Notably, Urine-Exos upregulated β-catenin expression through SDC1 transfer, further promoting UEC proliferation and migration. These findings were confirmed in a congenital hypospadias rat model induced by di(2-ethylhexyl) phthalate (DEHP). CONCLUSION This study reveals the therapeutic potential of Urine-Exos in hypospadias, mediated by the SDC1/β-catenin axis. Urine-Exos promote UEC proliferation and migration, thereby inhibiting the progression of hypospadias. These findings offer new insights and potential therapeutic targets for the management of congenital malformations.

[PMID: 38401686 DOI: 10.1016/j.yexcr.2024.113980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/18/2024] [Accepted: 02/19/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Hypospadias is a common congenital abnormality of the penile. Abnormal regulation of critical genes involved in urethral development leads to hypospadias. We used the Rab25-/- mice and foreskin fibroblasts transfected with lentivirus in vitro and in vivo to investigate the role of Rab25 in hypospadias. METHODS The expression levels of various molecules in tissue samples and foreskin fibroblasts were confirmed using molecular biology methods (western blotting, PCR, immunohistochemistry, etc.). A scanning electron microscope (SEM) was used to visualize the external morphology of genital tubercles (GTs) of gestation day (GD) 18.5 male wild-type (WT) and Rab25-/- mice. RESULTS An expanded distal cleft and V-shaped urethral opening were observed in GD 18.5 Rab25-/- mice. We demonstrated that Rab25 mediated hypospadias through the β1 integrin/EGFR pathway. In addition, silencing Rab25 inhibited cell proliferation and migration and promoted apoptosis in the foreskin fibroblasts; Ki-67- and TUNEL-positive cells were mainly concentrated near the urethral seam. CONCLUSION These findings suggest that Rab25 plays an essential role in hypospadias by activation of β1 integrin/EGFR pathway, and Rab25 is a critical mediator of urethral seam formation in GD18.5 male fetal mice.

Abstract
This study aimed to investigate the impact of mono(2-ethylhexyl) phthalate (MEHP) on the proliferation, apoptosis, and migration of human foreskin fibroblast cells (HFF-1) and the role of the JNK signaling pathway in cell migration. HFF-1 cells were randomly assigned to the control group with 0 MEHP exposure (M0) or the experimental groups with 25, 50, 100, 200, and 400 μmol/L MEHP exposure (M25, M50, M100, M200, and M400, respectively). After 24 and 48 h of MEHP exposure, the proliferation of HFF-1 cells in any group had no significant change. However, compared with the M0 group, the M200 and M400 groups presented substantially increased apoptosis of HFF-1 cells. Moreover, cell migration ability significantly decreased in all groups (p < 0.05). Additionally, the transcription and phosphorylated protein activation of JNK kinase in HFF-1 cells were substantially upregulated with the increase in MEHP exposure. Subsequently, HFF-1 cells were randomly divided into three groups: the DMSO blank control group, the 100 μM MEHP experimental group (M100), and the 100 μM MEHP plus 10 μM SP600125 (specific JNK inhibitor) experimental group (S10). The activation of JNK protein in HFF-1 cells was substantially downregulated in the S10 group. HFF-1 cells were also divided into the blank control group (M0). They were treated with 100 μM MEHP and varying concentrations of SP600125 (5, 10, and 15 μM for S5, S10, and S15, respectively). As the concentration of the antagonist increased, the migration ability of HFF-1 cells was returned to normal. Finally, the ROS in HFF-1 cells increased under MEHP exposure. This finding indicates that the regulation of cell migration by the JNK signaling pathway may be important in the occurrence of hypospadias.

[PMID: 37246119 DOI: 10.1016/j.jpurol.2023.05.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 04/30/2023] [Accepted: 05/09/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND Hypospadias, a congenital malformation of the penis, is one of the newborns' most common developmental defects. The incidence of hypospadias is increasing yearly, and its pathogenesis is closely related to genetic susceptibility and environmental exposure to endocrine disruptors. Exploring the hypospadias' key molecular regulatory mechanism is crucial to reducing its incidence. OBJECTIVE To examine the differential expression of Rab25 in hypospadias and normal penile tissue and to identify whether it is a candidate gene for exploring the mechanism of hypospadias. STUDY DESIGN This study included 18 children aged 1-6 years undergoing hypospadias repair surgery at the Children's Hospital of Chongqing Medical University, and foreskin samples were collected. Children diagnosed with cryptorchidism, intersex status, or endocrine abnormalities were excluded from this study. Another 18 children aged 3-8 years with phimosis were included in the control group. The specimens were used for immunohistochemistry, western blotting, immunofluorescence, and polymerase chain reaction to assess the expression of Rab25. RESULTS Rab25 protein expression was lower in the hypospadias group than in the control group [ (2.101 ± 0.1845), (0.7506 ± 0.1779), p = 0.0008 < 0.05). The hypospadias group showed decreased expression of Rab25 protein in the epithelial cell layer. Rab25 mRNA levels were downregulated in the foreskin of children with hypospadias compared with controls [(1.697 ± 0.2005), (0.7687 ± 0.2130), p = 0.0053 < 0.05)]. DISCUSSION Rab25 mRNA and protein expressions in the hypospadias group were significantly downregulated compared with the control group. This was consistent with the results of single-cell sequencing of fetal mice reproductive nodules at 15.5 days of gestation (Zhang Z, Liu Z, Zhang Q, et al., unpublished observations). Our study represents the first report of abnormal Rab25 expression in the foreskin tissue of patients with hypospadias. More detailed research on the relationship between Rab25 and urethral development could be conducted to reveal the molecular mechanism of hypospadias. CONCLUSION The expression of Rab25 in foreskin tissue was lower in the hypospadias group than in the control group. Rab25 is involved in the formation of the urethral seam and the occurrence of hypospadias. The potential mechanism by which Rab25 affects the canalization of the urethral plate needs to be further investigated.

Abstract
Birth defects of the external genitalia are among the most common in the world. Proper formation of the external genitalia requires a highly orchestrated process that involves special cell populations and sexually dimorphic hormone signaling. It is clear what the end result of the sexually dimorphic development is (a penis in the male versus clitoris in the female); however, the cell populations involved in the process remain poorly defined. Here, we used single-cell messenger RNA sequencing in mouse embryos to uncover the dynamic changes in cell populations in the external genitalia during the critical morphogenetic window. We found that overall, male and female external genitalia are largely composed of the same core cellular components. At the bipotential stage of development (embryonic day or E14.5), few differences in cell populational composition exist between male and female. Although similar in cell population composition, genetic differences in key sexual differentiation developmental pathways arise between males and females by the early (E16.5) and late (E18.5) differentiation stages. These differences include discrete cell populations with distinct responsiveness to androgen and estrogen. By late sexual differentiation (E18.5), unique cell populations in both male and female genitalia become apparent and are enriched with androgen- and estrogen-responsive genes, respectively. These data provide insights into the morphogenesis of the external genitalia that could be used to understand diseases associated with defects in the external genitalia.

This study aimed to investigate the expression of Fos proto-oncogene, AP-1 transcription factor subunit (c-Fos) in the genital tubercle (GT) of rats with di(2-ethylhexyl) phthalate (DEHP)-induced hypospadias and in the prepuce of patients with hypospadias compared with unaffected controls. Pregnant rats were given 750 mg/kg/day DEHP orally from gestational days 12-19. Western blotting showed that c-Fos expression was increased in DEHP-induced hypospadiac male offspring. In addition, 30 prepuce tissue specimens obtained during hypospadias repair surgery were divided into 2 groups: the mild hypospadias group (n = 15) and the severe hypospadias group (n = 15). Fifteen normal prepuce tissue specimens were harvested during elective circumcision as normal controls. Real-time quantitative polymerase chain reaction, western blotting and immunohistochemistry analyses were used to assess c-Fos expression. c-Fos protein levels were higher in the GT of DEHP-induced rats than in that of control rats. c-Fos mRNA and protein levels were also higher in the hypospadias groups than in the control group (p < 0.05, p < 0.001), and c-Fos protein levels were significantly higher in the severe hypospadias group than in the mild hypospadias group (p < 0.01). The expression of c-Fos was increased in both the GT of DEHP-induced hypospadiac rats and the prepuce of hypospadias patients. Thus, c-Fos overexpression might contribute to hypospadias.Abbreviations: DEHP: di(2-ethylhexyl) phthalate; c-Fos: Fos proto-oncogene, AP-1 transcription factor subunit; Mafb: the masculinization-regulatory gene v-maf musculoaponeurotic fibrosarcoma oncogene family, protein B; GT: genital tubercle; ED: embryonic day; AGD: anogenital distance; AGI: anogenital distance index; ED: embryonic day.

Front Pediatr 2020; 8:586287. [PMID: 33425810 PMCID: PMC7786202 DOI: 10.3389/fped.2020.586287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 11/24/2020] [Indexed: 12/02/2022] Open
Abstract
Background and Objective: Mild hypospadias is a birth congenital condition characterized by the relocation of the male urethral meatus from its typical anatomical position near the tip of the glans penis, to a lower ventral position up to the brim of the glans corona, which can also be accompanied by foreskin ventral deficiency. For the most part, a limited number of cases have known etiology. We have followed a high-throughput proteomics approach to study the proteome in mild hypospadias patients. Methods: Foreskin samples from patients with mild hypospadias were collected during urethroplasty, while control samples were collected during elective circumcision (n = 5/group). A high-throughput, quantitative proteomics approach based on multiplexed peptide stable isotope labeling (SIL) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was used to ascertain protein abundance changes in hypospadias patients when compared to control samples. Results: A total of 4,815 proteins were quantitated (2,522 with at least two unique peptides). One hundred and thirty-three proteins from patients with mild hypospadias showed significant abundance changes with respect to control samples, where 38 proteins were increased, and 95 proteins were decreased. Unbiased functional biological analysis revealed that both mitochondrial energy production and apoptotic signaling pathways were enriched in mild hypospadias. Conclusions: This first comprehensive proteomics characterization of mild hypospadias shows molecular changes associated with essential cellular processes related to energy production and apoptosis. Further evaluation of the proteome may expand the search of novel candidates in the etiology of mild hypospadias and could also lead to the identification of biomarkers for this congenital urogenital condition.

Zhu YP, Zhao W, Sun WL, Zhao S, Chen M, Pan L, Zhou Z, Xia SJ, Jiang JT. Di-n-butyl phthalate (DBP) reduces epithelial-mesenchymal transition via IP3R in hypospadias during maternal exposure. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 192:110201. [PMID: 32028152 DOI: 10.1016/j.ecoenv.2020.110201] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 01/07/2020] [Accepted: 01/10/2020] [Indexed: 05/23/2023]
Abstract
OBJECTIVE This study focused on the oxidative stress effect of di-n-butyl phthalate (DBP) on development of the urinary system. METHODS We examined the mRNA expression of genital tubercle (GT) in control and DBP induced hypospadias group by Affymetrix Rat 230 2.0 Array. Real-time PCR and Western Blot were used to detect the protein and mRNA expression levels of inositol-1,4,5-triphate-receptor (IP3R) and epithelial-mesenchymal-transition (EMT)-related molecular markers, such as E-cadherin, β-Catenin, Snail, N-cadherin, in the GT of hypospadiac male rats and controls. The results of array were further confirmed in vitro. The changes of intracellular calcium concentration in urethral epithelial cells were detected by Fluo-3-AM before and after DBP treatment. The levels of reactive oxygen species (ROS) in urethral epithelial cells were measured by DCFH-DA with different concentrations of DBP (0, 1, 10, 100 μmol/L) treatment. RESULTS The mRNA expression profiles of GT in control and DBP induced hypospadias group showed high expression of IP3R and the abnormalities of EMT. Compared to the control group, the expression levels of IP3R, E-cadherin and β-Catenin increased at both the protein and mRNA levels. However the expression levels of Snail and N-cadherin decreased. The intracellular calcium concentration increased significantly after DBP treatment. The effect of DBP on urethral epithelial cells was linked to the generation of oxidative stress. CONCLUSION DBP can influence the development of GT through its oxidative stress effect, which significantly increases the concentration of calcium and inhibits EMT in urethral epithelial cells, and block the fusion process of urethral groove, causing the occurrence of hypospadias. This study provides a new understanding of DBP's molecular mechanisms on hypospadias and may lead to new treatment strategies for the disease.

TGF-β1 relieves epithelial-mesenchymal transition reduction in hypospadias induced by DEHP in rats. Pediatr Res 2020; 87:639-646. [PMID: 31726466 DOI: 10.1038/s41390-019-0622-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 08/19/2019] [Accepted: 09/29/2019] [Indexed: 11/09/2022]
Abstract
BACKGROUNDS To investigate the potential mechanism of hypospadias induced by DEHP in rats to reveal the preventative effect of TGF-β1 in hypospadias induced by DEHP via the reduction of EMT. METHODS Time-mated Sprague-Dawley rats underwent cesarean section, and the penises of male pups were collected after exposure to corn oil or DEHP to establish a rat model of hypospadias and to further study the molecular mechanisms of hypospadias in vivo. In addition, the penises were cultured and treated with MEHP or MEHP+TGF-β1 in vitro. Subsequently, histomorphology and elements in TGF-β/Smad signaling pathway changes were evaluated using scanning electron microscopy, immunofluorescence, polymerase chain reaction, and western blot. RESULTS The development of rat penis and urethral seam fusion were delayed after the treatment with DEHP in vivo or MEHP in vitro compared with the Control group. Moreover, TGF-β1, Smad2/Smad3, and the mesenchymal biomarkers, including α-SMA, N-cadherin, and Vimentin, were decreased. However, the epithelial biomarkers, including E-cadherin, ZO-1, β-catenin, and occludin, were increased. In addition, TGF-β1 could relieve all of the above changes. CONCLUSION Gestational DEHP exposure could lead to hypospadias by reducing urethral EMT. Moreover, TGF-β1 could prevent it by regenerating EMT through activating the TGF-β/Smad signal pathway.

Abstract
As a specific inhibitor of serine/threonine protein phosphatases, okadaic acid (OA) has been found to be a tumor promoter. However, whether OA plays a role in metastasis of hepatocellular carcinoma (HCC) has not been well elucidated. In this study, Hep3B and HepG2 cells were treated with different doses of OA and the cell viability was determined by CCK8 test. As a result, Hep3B and HepG2 cells showed no obvious cytotoxicity after OA treatment below 20 or 25 nM for 12 or 24 hours. However, wound healing, invasion, and migration abilities of HCC cells were significantly enhanced in the OA-treated groups than those of the control group (P < .05), measured by cell scratching and BD transwell assays. Moreover, we found that the expression of epithelial-mesenchymal transition (EMT)-related key factors was changed upon OA treatment in a dose-dependent manner. In addition, the activity of protein phosphatase 2A (PP2A) in OA-treated cells was also decreased significantly compared with the control cells (P < .05). Interfering of PP2A subunit A or C caused a similar expression change of EMT-related key factors as the OA treatment in HCC cells. Our results suggest that OA promotes the EMT process of HCC cells by inhibiting the activity of PP2A.
