[PMID: 35723319 PMCID: PMC8929108 DOI: 10.3390/cimb44020033] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/15/2022] [Accepted: 01/16/2022] [Indexed: 12/12/2022] Open
Abstract
Sheep testes undergo a dramatic rate of development with structural changes during pre-sexual maturity, including the proliferation and maturation of somatic niche cells and the initiation of spermatogenesis. To explore this complex process, 12,843 testicular cells from three males at pre-sexual maturity (three-month-old) were sequenced using the 10× Genomics ChromiumTM single-cell RNA-seq (scRNA-seq) technology. Nine testicular somatic cell types (Sertoli cells, myoid cells, monocytes, macrophages, Leydig cells, dendritic cells, endothelial cells, smooth muscle cells, and leukocytes) and an unknown cell cluster were observed. In particular, five male germ cell types (including two types of undifferentiated spermatogonia (Apale and Adark), primary spermatocytes, secondary spermatocytes, and sperm cells) were identified. Interestingly, Apale and Adark were found to be two distinct states of undifferentiated spermatogonia. Further analysis identified specific marker genes, including UCHL1, DDX4, SOHLH1, KITLG, and PCNA, in the germ cells at different states of differentiation. The study revealed significant changes in germline stem cells at pre-sexual maturation, paving the way to explore the candidate factors and pathways for the regulation of germ and somatic cells, and to provide us with opportunities for the establishment of livestock stem cell breeding programs.

Abstract
UCHL1 is expressed specifically in the brain and gonads of almost all studied model organisms including Drosophila, zebrafish, amphibians, and mammals, suggesting a high degree of evolutionary conservation in its structure and function. Although UCHL1 has been involved in spermatogenesis in mice, its specific expression in mammal placenta remains elusive. Our previous work has revealed that UCHL1 is highly expressed in oocytes, and has been involved in mouse ovarian follicular development. Here, we further examined UCHL1 expression change in endometria during early natural pregnancy, with different stages of the estrous cycle and pseudopregnancy as control. The UCHL1 gene deletion model showed that UCHL1 protein is associated with endometrial development, and its deletion leads to infertility. Notably, we demonstrate evidence showing the distinct expression pattern of UCHL1: weak expression over the uterine endometria, strong expression in decidualized stromal cells at the implantation site with a peak at pregnancy D6, and a shift with primary decidualization to secondary decidualized zones. Using the delayed implantation, the delayed implantation activation, and the artificial decidualization models, we have demonstrated that strong expression of UCHL1 occurred in response to decidualization and estrogen stimulation. These observations suggest that during the early proliferation and differentiation of mouse uterine decidua, UCHL1 expression is up-regulated, and formed an unique intracellular distribution mode. Therefore, we proposed that UCHL1 is involved in decidualization, and possibly in response to estrogen regulation.

Analysis of the autophagy gene expression profile of pancreatic cancer based on autophagy-related protein microtubule-associated protein 1A/1B-light chain 3. World J Gastroenterol 2019; 25:2086-2098. [PMID: 31114135 PMCID: PMC6506580 DOI: 10.3748/wjg.v25.i17.2086] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 03/20/2019] [Accepted: 04/10/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Pancreatic cancer is a highly invasive malignant tumor. Expression levels of the autophagy-related protein microtubule-associated protein 1A/1B-light chain 3 (LC3) and perineural invasion (PNI) are closely related to its occurrence and development. Our previous results showed that the high expression of LC3 was positively correlated with PNI in the patients with pancreatic cancer. In this study, we further searched for differential genes involved in autophagy of pancreatic cancer by gene expression profiling and analyzed their biological functions in pancreatic cancer, which provides a theoretical basis for elucidating the pathophysiological mechanism of autophagy in pancreatic cancer and PNI.
AIM To identify differentially expressed genes involved in pancreatic cancer autophagy and explore the pathogenesis at the molecular level.
METHODS Two sets of gene expression profiles of pancreatic cancer/normal tissue (GSE16515 and GSE15471) were collected from the Gene Expression Omnibus. Significance analysis of microarrays algorithm was used to screen differentially expressed genes related to pancreatic cancer. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were used to analyze the functional enrichment of the differentially expressed genes. Protein interaction data containing only differentially expressed genes was downloaded from String database and screened. Module mining was carried out by Cytoscape software and ClusterOne plug-in. The interaction relationship between the modules was analyzed and the pivot nodes between the functional modules were determined according to the information of the functional modules and the data of reliable protein interaction network.
RESULTS Based on the above two data sets of pancreatic tissue total gene expression, 6098 and 12928 differentially expressed genes were obtained by analysis of genes with higher phenotypic correlation. After extracting the intersection of the two differential gene sets, 4870 genes were determined. GO analysis showed that 14 significant functional items including negative regulation of protein ubiquitination were closely related to autophagy. A total of 986 differentially expressed genes were enriched in these functional items. After eliminating the autophagy related genes of human cancer cells which had been defined, 347 differentially expressed genes were obtained. KEGG pathway analysis showed that the pathways hsa04144 and hsa04020 were related to autophagy. In addition, 65 clustering modules were screened after the protein interaction network was constructed based on String database, and module 32 contains the LC3 gene, which interacts with multiple autophagy-related genes. Moreover, ubiquitin C acts as a pivot node in functional modules to connect multiple modules related to pancreatic cancer and autophagy.
CONCLUSION Three hundred and forty-seven genes associated with autophagy in human pancreatic cancer were concentrated, and a key gene ubiquitin C which is closely related to the occurrence of PNI was determined, suggesting that LC3 may influence the PNI and prognosis of pancreatic cancer through ubiquitin C.

Iridoviral infection can be reduced by UCHL1-loaded exosomes from the testis of Chinese giant salamanders (Andrias davidianus). Vet Microbiol 2018; 224:50-57.

Abstract
Chinese giant salamander iridovirus (CGSIV) is a large double-stranded DNA virus that infects Chinese giant salamanders (CGSs) and is responsible for a high mortality rate of CGSs under certain conditions. It is generally believed that CGSIV is a horizontally transmitting virus that affects lower vertebrates. Exosomes from tissues and cells affect the mechanism of viral infections. UCHL1, a deubiquitinating enzyme, is indirectly involved in virus propagation via cytokine and chemokine suppression. In our study, a few CGSIVs were detected in the testis of the special symptom CGSs using PCR and immunofluorescence analysis. The exosomes originating in the testicular fluid was isolated and identified using the Nanosight NS300 system and scanning electron microscopy. The UCHL1-loaded exosomes may resist CGSIV entry by fusing with and remodeling CGSIV. UCHL1 in the primary testicular fibroblasts was maintained at a stable level to inhibit the infection and replication of CGSIV by secreting and sorting exosomes. These data provided a new insight into CGSIV being a type of horizontally transmitting virus.

Abstract
We characterized the Andrias davidianus T-box 1 (Tbx1) gene. Tbx1 expression was high in testis and low in other examined tissues. Immunohistochemistry detected tbx1 expression in somatic and germ cells 62 days post-hatching (dph), prior to gonad differentiation. At 210 dph, after gonad differentiation, tbx1 was expressed in spermatogonia and testis somatic cells and in granulosa cells in ovary. Tbx1 expression was up-regulated in ovary after high temperature treatment. In the neomale, tbx1 expression showed a similar profile to normal males, and vice-versa for genetic male. Over-expression of tbx1 in females after injection of TBX1 protein down-regulated the female-biased genes cyp19a and foxl2 and up-regulated the male-biased amh gene. When tbx1 was knocked down by tbx1/siRNA, cyp19a and foxl2 expression was up-regulated, and expression of amh, cyp26a, dmrt1, and wt1 was down-regulated. Results suggest that tbx1 influenced sex-related gene expression and participates in regulation of A. davidianus testis development.

Abstract
The aim of this study was to characterise the molecular structure of the oestrogen receptor ERα and to evaluate the effect of bisphenol A (BPA) on ERα expression during sexual development of the Chinese giant salamander (Andrias davidianus). The ERα cDNA of A. davidianus includes an open reading frame of 1755bp (encoding 584 amino acids), a 219-bp 5' untranslated region (UTR) and a 611-bp 3'UTR. A polyadenylation signal was not found in the 3'UTR. Amino acid sequence analysis showed high homology between ERα of A. davidianus and that of other amphibians, such as Andrias japonicas (99.66% identity) and Rana rugose (81.06% identity). In 3-year-old A. davidianus, highest ERα expression was observed in the liver and gonads. During different developmental stages in A. davidianus (from 1 to 3 years of age), ERα expression in the testes increased gradually. ERα was localised in the epithelial cells of seminiferous lobules and in interstitial cells. ERα-positive cells were more abundant in the interstitial tissue during testicular development. ERα was located in the nucleus of oocytes during ovary development. We found that the sex of 6-month-old A. davidianus larvae could not be distinguished anatomically. The sex ratio did not change after larvae were treated with 10μM BPA for 1 month. However, BPA treatment reduced bodyweight and ERα expression in the gonads in male larvae.
