J Pediatr Urol 2024:S1477-5131(24)00286-9. [PMID: 38880668 DOI: 10.1016/j.jpurol.2024.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 05/23/2024] [Accepted: 05/27/2024] [Indexed: 06/18/2024]
Abstract
INTRODUCTION Cryptorchidism is one of the most common congenital anomalies in male children, occurring in 2-5% of full-term male infants. Both genetic and environmental factors are observed to play a role in its etiology. A study conducted in Japan identified the AXIN1 gene as being associated with cryptorchidism. OBJECTIVE We aimed to conduct a pilot study on AXIN1 gene polymorphism in Turkish children with cryptorchidism, and whether AXIN1 gene polymorphism is a risk factor for cryptorchidism. STUDY DESIGN Between January 2023 and December 2023, we have planned a prospective controlled study including 84 boys operated for cryptorchidism as study group, and 96 boys operated for circumcision as control group. The remaining blood samples of preoperative laboratory tests in ethylenediamine tetraacetic acid (EDTA) tubes were kept at -20 Co freezer for genomic studies. Patient demographics, physical examination and operative findings were recorded, study patients were grouped according to testis localization. After collecting all samples, genomic DNA isolation procedure was done, and analysis of the 3 polymorphisms (rs12921862, rs1805105 and rs370681) of AXIN1 gene was performed using conventional Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) method. Genotype and allele frequencies of each group was analyzed and compared. RESULTS The most common location of cryptorchid testis was proximal inguinal (53%), followed by distal inguinal (25.3%), bilateral (13.3%), and intra-abdominal (8.4%). Regarding the 3 polymorphisms of AXIN1 gene, there was no significant difference between study and control groups, in terms of genotype and allele frequencies (P > 0.05). Eight haplotype blocks were estimated for 3 polymorphisms of AXIN1. However, no significant difference was observed between study and control groups regarding haplotype distributions (P > 0.05). In addition, the comparison of the localization of testis with AXIN1 gene polymorphism did not show any significant difference among cryptorchid testis groups (P > 0.05). DISCUSSION The AXIN1 gene is located on chromosome 16p and its polymorphisms have been associated with various diseases. In a Chinese study, the rs370681 polymorphism was found to be associated with cryptorchidism. However, our results showed no association between the AXIN1 gene haplotypes for the studied polymorphisms and cryptorchidism. CONCLUSION In this study we have investigated the AXIN1 gene polymorphism in Turkish children with cryptorchidism as a pilot study. Although we could not identify any difference as compared to control group, further research is necessary to uncover the underlying molecular mechanisms contributing to the development of cryptorchidism.

Abstract
Undescended testis (UDT, cryptorchidism) is the most common congenital anomaly of the genital tract. Despite its high incidence, the management of UDT varies between specialties (urology, pediatric surgery, pediatric urology, pediatric endocrinology). Therefore, as the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we requested experts around the world to express their own personal approaches against various case scenarios of UDT in order to explore their individual reasoning. We intended to broaden the perspectives of our colleagues who deal with the treatment of this frequent genital malformation.

The RXFP2-PLC/PKC signaling pathway mediates INSL3-induced regulation of the proliferation, migration and apoptosis of mouse gubernacular cells. Cell Mol Biol Lett 2023; 28:16. [PMID: 36849880 PMCID: PMC9972740 DOI: 10.1186/s11658-023-00433-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 02/20/2023] [Indexed: 03/01/2023] Open
Abstract
BACKGROUND Testicular hypoplasia can affect the sexual and reproductive ability in adulthood, and even increase the risk of cancer. Abnormal development of the gubernaculum is one of the important factors of testicular hypoplasia. Therefore, a study of the structure and function of the gubernaculum is an important but neglected new breakthrough point for investigating the normal/abnormal development of the testis. Previous findings showed that Insulin like factor 3 (INSL3) is a key factor regulating the growth of gubernaculum, however, the mechanism by which INSL3 acts on the gubernaculum remains unknown. Therefore, we probed the mechanism associated with INSL3-induced the proliferation, migration, and apoptosis of gubernacular cells in mice. METHODS A culture cell model of neonatal mice gubernaculum is established by INSL3 intervention. We blocked PLC/PKC signaling pathway with U73122 pretreat to investigate the role of the PLC/PKC signaling pathway. The changes of cell proliferation, migration, and apoptosis were detected by molecular biological methods. In addition, the levels of PCNA and F-action were detected by immunofluorescence and western blotting. RESULTS We found that INSL3 can promote the proliferation and migration of gubernacular cells and inhibit their apoptosis, meanwhile, INSL3 significantly up-regulated PLC/PKC protein phosphorylation. However, treatment with the PLC/PKC signaling pathway inhibitor U73122 significantly inhibited these effects of INSL3. Besides, we found that INSL3 could up-regulate the protein expression level of PCNA and F-actin, while the PCNA and F-actin expression was significantly weakened after U73122 pretreatment. CONCLUSIONS This research revealed that INSL3 binding to RXFP2 may up-regulate the expression levels of PCNA and F-actin by activating the PLC/PKC signaling pathway to promote the proliferation and migration of gubernacular cells. It suggests that the RXFP2-PLC/PKC axis may serve as a novel molecular mechanism by which INSL3 regulates growth of the gubernaculum.

The Role of microRNAs in the Gonocyte Theory as Target of Malignancy: Looking for Potential Diagnostic Biomarkers. Int J Mol Sci 2022; 23:ijms231810526. [PMID: 36142439 PMCID: PMC9505168 DOI: 10.3390/ijms231810526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/30/2022] [Accepted: 08/06/2022] [Indexed: 11/16/2022] Open
Abstract
Some pediatric patients with cryptorchidism preserve cells with gonocyte characteristics beyond their differentiation period, which could support the theory of the gonocyte as a target for malignancy in the development of testicular neoplasia. One of the key molecules in gonocyte malignancy is represented by microRNAs (miRNAs). The goal of this review is to give an overview of miRNAs, a class of small non-coding RNAs that participate in the regulation of gene expression. We also aim to review the crucial role of several miRNAs that have been further described in the regulation of gonocyte differentiation to spermatogonia, which, when transformed, could give rise to germ cell neoplasia in situ, a precursor lesion to testicular germ cell tumors. Finally, the potential use of miRNAs as diagnostic and prognostic biomarkers in testicular neoplasia is addressed, due to their specificity and sensitivity compared to conventional markers, as well as their applications in therapeutics.

Abstract
OBJECTIVE To assess the testicular volume in children with unilateral cryptorchidism of different ages in Hainan Province, China. METHODS The study included 424 children (ranging in age from 0 month to 4 years) with unilateral cryptorchidism or normal who were treated from 2017 to 2021 at our institution. They were divided into different groups according to age. We evaluated the correlation of testicular volume between the children with cryptorchidism and the normal children among different groups. RESULTS There was a significant difference in testicular volume between the affected side and the healthy side. There was no difference in testicular volume between the left side and the right side of each control group. There were significant differences between the affected side of cryptorchid groups and the same side of the control groups. There were no significant differences between the healthy side of cryptorchid groups and the same side of the control groups. There were no significant differences between the affected side of left cryptorchid groups and right cryptorchid groups. There were no significant differences between the healthy side of left cryptorchid groups and right cryptorchid groups. There were significant differences in testicular volume among different age groups of the control group, while there were no differences in the cryptorchid groups. CONCLUSIONS The development of testicular volume in children with unilateral inguinal cryptorchidism is affected in earlier age, and there was no compensatory testicular adaptation in the healthy testis.
