- 4-Nonylphenol (NP) is an environmental endocrine disruptor widely used in consumer products. Previous studies have shown that NP can interfere with hormone synthesis and metabolism in humans and animals, leading to male reproductive dysfunction. This study utilized the scRNA-seq method to evaluate cell populations and their heterogeneity, aiming to elucidate the toxic mechanisms of NP exposure on testicular cells. We demonstrate, for the first time, the transcriptomic characteristics of testicular single cells in adolescent mice exposed to NP. Adolescent mice, initially exposed at 4 weeks of age, were subsequently analyzed at sexual maturity after a continuous exposure period of 3 months. The blank control and NP-exposed groups underwent scRNA-seq analysis, identifying ten cell populations. The results showed that after NP exposure, the number of germline cells was remarkably reduced compared to the control group. NP exposure significantly decreased the protein expression of the four common differentially expressed genes (DEGs) (Cmtm2b, Rpl28, Adam32, and Pgam2). The DEGs enriched in the GO functions of the four germline cell types were spermatogenesis and spermatid development. KEGG analysis showed that the DEGs were enriched in the oxidative phosphorylation, and ROS signaling pathways. Further analysis of intercellular interactions revealed that NP exposure altered intercellular communication between germ cells, with the NECTIN3-NECTIN2 receptor-ligand interactions activating between spermatogonia, Sertoli, and Leydig cells. Germ cells bind to Sertoli and Leydig cells via NECTIN3-NECTIN2 receptor ligands. Somatic cells bind to RS and ES through GRN-SORT1 receptor ligands. CADM1-CADM1 receptor-ligand interactions enhances between germ and Sertoli cells. Our study provides new insights into the potential impacts of NP on spermatogenesis and sperm function, emphasizing the importance of environmental hormones in male fertility issues. - Source: PubMed

Zhao XueTian YananZhou DanTang XiaojuanZhou XiaoyangWang XuelinHe YanYu PengxiaHuang JiaolongTan YanDuan Peng - Sperm-egg interactions involve a complex series of molecular events. Among these, the acrosome reaction (AR) is a prerequisite for sperm penetration, facilitating the exposure of multiple acrosomal proteins that enhance sperm binding or penetration of the outer layer of the egg; however, the specific molecules involved in this process vary across species. A disintegrin and metalloproteinase (ADAM) proteins are transmembrane glycoproteins that play a role in sperm-egg interactions, with notable differences among ADAM isoforms. In a previous characterization of the chicken sperm membrane proteome, ADAM32 metallopeptidase domain 32-like 2 (ADAM32L2), a protein structurally homologous to mammalian ADAMs, but absent in mammals, was identified. ADAM32L2 was located in the acrosomal region, underwent processing during the AR, similar to certain mammalian sperm ADAMs, and likely contributed to sperm binding to the inner perivitelline layer (IPVL) in chickens. Using various protease inhibitors, it was confirmed that sperm protease activity was involved in multiple stages of sperm interaction with the IPVL. Using a specific antibody, ADAM32L2 was predominantly expressed in the testis and localized to the sperm acrosomal region. Upon separation of the acrosome cap through an inherent AR process in chicken sperm, the 80 kDa acrosomal ADAM32L2 was processed into a 45 kDa C-terminal fragment during AR. Although zymography did not detect metalloproteinase activity in this fragment, a purified ADAM32L2 antibody inhibited sperm penetration of the IPVL, suggesting that the processed form was involved in IPVL binding. These findings elucidate the mechanism of sperm-IPVL interactions and offer new insights into the functional role of ADAM proteins in avian sperm. - Source: PubMed

Mohtar Mohamad Shuib Bin MohamadSetiawan RanggaKuwabara MaikoAsano Atsushi - : The membrane protein a disintegrin and metalloproteases (ADAMs) are highly expressed in various human carcinomas and play an important role in cancer characteristics. And among these, ADAM32 is highly expressed in hepatoblastoma (HBL) and plays an important role in oncogenic properties. However, the regulatory mechanism has not been determined. Recently, it has been reported that some ADAMs are regulated by HIF, which is an important transcription factor in response to hypoxia. Therefore, we decided to study the regulatory mechanisms of under hypoxic conditions by using HBL, breast, and lung cancer cell lines. : When these cells were exposed to 1% O (hypoxia), it was found that the levels of increased at 48 h in HepG2, MCF7, and MDA-MB-231 but not in HUH-6 or lung cancer lines. However, the promoter activity of the gene in HepG2 remained unchanged under hypoxic conditions, suggesting that the level of in HBL is regulated by factors other than the promoter activity. From the microarray data, we found that the level of , which is an mA-related molecule, correlated with that of , and these levels were decreased by knockdown. And knockdown decreased the expression of ADAM32 and attenuated the increased expression of ADAM32 under hypoxic conditions. : This study demonstrated that the oncogenic gene is regulated by IGF2BP2 and that IGF2BP2 could be a molecular target for HBL anticancer therapy. - Source: PubMed

Fukazawa TakahiroTanimoto KeijiKojima MasatoKanawa MasamiHirohashi NobuyukiHiyama Eiso - The characterization of sperm and seminal plasma proteins is essential for understanding bull fertility and optimizing reproductive success in buffalo bulls. Despite its importance, the reproductive proteomic of Toraya buffalo, an indigenous breed in Indonesia, remains largely unexplored. This study aimed to examine the seminal plasma and sperm proteins of Toraya buffalo to uncover those critical for reproductive functions. Semen samples were collected from eight Toraya buffalo bulls aged 4 to 10 years. Protein profiling was performed using one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (1D-SDS-PAGE), followed by in-gel digestion and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. Bioinformatics tools, including UniProt, PANTHER, DAVID, and STRING, were utilized to identify and annotate the detected proteins. This study successfully identified four key reproductive proteins: ADAM32 in seminal plasma and ZPBP, SPACA3, and CCDC136 in sperm. These proteins are essential for sperm motility, energy production, and acrosome formation, which are critical processes for fertilization. Additionally, many identified proteins were associated with metabolic pathways, particularly the tricarboxylic acid (TCA) cycle, which plays a fundamental role in energy supply for sperm function. In conclusion, this study offers the first comprehensive proteomic identification of seminal plasma and sperm proteins associated with reproductive functions in the Toraya buffalo. The findings highlight the presence of key proteins in sperm, including ZPBP, SPACA3, and CCDC136, as well as the identification of ADAM32 in seminal plasma, contributing to a deeper understanding of buffalo reproductive biology. - Source: PubMed

Maulana TulusSaid SyahruddinArifiantini Raden IisJakaria JakariaGunawan Asep - Genome-wide association studies (GWAS) are one of the best ways to look into the connection between single-nucleotide polymorphisms (SNPs) and the phenotypic performance. This study aimed to identify the genetic variants that significantly affect the important reproduction traits in Vrindavani cattle using genome-wide SNP chip array data. In this study, 96 randomly chosen Vrindavani cows were genotyped using the Illumina Bovine50K BeadChip platform. A linear regression model of the genome-wide association study was fitted in the PLINK program between genome-wide SNP markers and reproduction traits, including age at first calving (AFC), inter-calving period (ICP), dry days (DD), and service period (SP) across the first three lactations. Information on different QTLs and genes, overlapping or adjacent to genomic coordinates of significant SNPs, was also mined from relevant databases in order to identify the biological pathways associated with reproductive traits in bovine. The Bonferroni correction resulted in total 39 SNP markers present on different chromosomes being identified that significantly affected the variation in AFC (6 SNPs), ICP (7 SNPs), DD (9 SNPs), and SP (17 SNPs). Novel potential candidate genes associated with reproductive traits that were identified using the GWAS methodology included UMPS, ITGB5, ADAM2, UPK1B, TEX55, bta-mir-708, TMPO, TDRD5, MAPRE2, PTER, AP3B1, DPP8, PLAT, TXN2, NDUFAF1, TGFA, DTNA, RSU1, KCNQ1, ADAM32, and CHST8. The significant SNPs and genes associated with the reproductive traits and the enriched genes may be exploited as candidate biomarkers in animal improvement programs, especially for improved reproduction performance in bovines. - Source: PubMed
