Abstract
"White pollution" has a significant impact on male reproduction. Di-n-butyl phthalate (DBP) is one of the most important factors in this type of pollution. Currently, research from international sources has demonstrated the significant reproductive toxicity of DBP. However, most of these studies have focused mainly on hormones expression at the protein and mRNA levels and the specific molecular targets of DBP and its mechanisms of action remain unclear. In this study, we established a Sprague Dawley pregnant mouse model exposed to DBP, and all male offspring were immediately euthanized at birth and bilateral testes were collected. We found through transcriptome sequencing that cell apoptosis and MAPK signaling pathway are the main potential pathways for DBP induced reproductive toxicity. Molecular biology analyses revealed a significant increase in the protein levels of JNK1(MAPK8) and BAX, as well as a significant increase in the BAX/BCL2 ratio after DBP exposure. Therefore, we propose that DBP induces reproductive toxicity by regulating JNK1 expression to activate the MAPK signaling pathway and induce reproductive cell apoptosis. In conclusion, our study provides the first evidence that the MAPK signaling pathway is involved in DBP-induced reproductive toxicity and highlights the importance of JNK1 as a potential target of DBP in inducing reproductive toxicity.

J Cell Physiol 2023; 238:610-630. [PMID: 36745473 DOI: 10.1002/jcp.30952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 12/12/2022] [Accepted: 01/09/2023] [Indexed: 02/07/2023]
Abstract
Currently, studies have analyzed the formation mechanism of primordial germ cell (PGC) at the transcriptional level, but few at the protein level, which made the mechanism study of PGC formation not systematic. Here, we screened differential expression proteins (DEPs) regulated PGC formation by label-free proteomics with a novel sampling strategy of embryonic stem cells and PGC. Analysis of DEPs showed that multiple key events were involved, such as the transition from glycolysis to oxidative phosphorylation, activation of autophagy, low DNA methylation ensured the normal formation of PGC, beyond that, protein ubiquitination also played an important role in PGC formation. Importantly, the progression of such events was attributed to the inconsistency between transcription and translation. Interestingly, MAPK, PPAR, Wnt, and JAK signaling pathways not only interact with each other but also interact with different events to participate in the formation of PGC, which formed the PGC regulatory network. According to the regulatory network, the efficiency of PGC formation in induction system can be significantly improved. In conclusion, our results indicate that chicken PGC formation is a complex process involving multiple events and signals, which provide technical support for the specific application in PGC research.

Retinoic acid promotes formation of chicken (Gallus gallus) spermatogonial stem cells by regulating the ECM-receptor interaction signaling pathway. Gene 2022; 820:146227. [PMID: 35124150 DOI: 10.1016/j.gene.2022.146227] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 12/09/2021] [Accepted: 01/13/2022] [Indexed: 01/18/2023]
Abstract
Spermatogonial stem cells (SSCs) are the basis of spermatogenesis. Systematically exploring the critical factors associated with the formation of SSCs will provide new insight to improve the formation efficiency, and their practical application. Here we explore the regulatory mechanism of the ECM-receptor interaction signaling pathway and related genes during differentiation of SSCs in chicken. Firstly, the positive cell rate of SSCs protein marker was detected by immunofluorescence and flow cytometry and qRT-PCR was used to identify, the expression of related marker genes after 10 days of RA-induction. Secondly, the ESCs on 0d/ 4d /10d after RA- induction/self-differentiation were collected, and the total RNA was then extracted from cells. Finally, high-throughput analysis methods (RNA-seq) were used to sequence the transcriptome of these cells. After PCA analysis of the RNA-seq data, Venny analysis, GO and KEGG enrichment were further used to find the key signaling pathways and genes in the RA-induction process. The results showed that on day 10 of RA-induction, grape cluster growth cells expressed integrinβ1, the specific marker protein of SSCs cells, and the integrinβ1 positive rate was 35.1%. Also, SSCs marker genes CVH, Integrinβ1, Integrinα6 were significantly up-regulated during RA-induction. Moreover, the significantly enriched pathway, ECM-receptor interaction signaling, in current study may play a crucial role in RA-induction. Then, JASPAR was used to predict the differential gene transcription factors in the signaling pathway, finding that RA receptor was a transcription factor of COL5A1, COL5A2 and COL3A1. The qRT-PCR results showed that the expression levels of RA receptors (RXRA, RARA and RXRG) and the predicted genes (COL5A1, COL5A2 and COL3A1) were both significantly increased during RA-induction. Also, dual-luciferase reporter assay showed that RA could affect the luciferin activities of COL5A1, COL5A2 and COL3A1. These results suggest that RA plays a crucial role in the formation of chicken spermatogonial stem cells via the transcription levels of COL5A1, COL5A2 and COL3A1 to regulate the ECM-receptor interaction signaling pathway. Additionally, knockdown of COL5A1/COL5A2/COL3A1 could effectively reduce the formation efficiency of SSCs. This indicated that the interference of RA receptor binding genes in the ECM-receptor interaction signaling pathway could decrease the efficiency of RA induced SSCs formation. Therefore, this study concludes that RA promotes formation of chicken spermatogonial stem cells by regulating the ECM-receptor interaction signaling pathway.

Abstract
Circular RNAs (circRNAs) are a special class of noncoding RNA molecules that regulate many different biological processes. Myogenesis, a complex process, is primarily regulated by myogenic regulatory factors (MRFs) and various noncoding RNAs. However, the functions and regulatory mechanisms of circRNAs in myoblast development are unclear. In this study, we analyzed circRNA sequencing data of bovine myocyte tissues and identified circACTA1. Functional assays showed that circACTA1 could inhibit bovine myocyte proliferation and promote cell apoptosis and cytodifferentiation. In addition, circACTA1 could promote muscle repair in vivo. Mechanistically, luciferase assay and RNA immunoprecipitation were used to examine the interaction between circACTA1, miR-199a-5p, miR-433, and the target genes MAP3K11 and MAPK8. Meanwhile, we found that miR-199a-5p and miR-433 could suppress the expression of MAP3K11 and MAPK8, respectively. However, circACTA1 could mitigate this effect and activate the JNK signaling pathway. In conclusion, our results suggest that circACTA1 regulates the multiplication, apoptosis, and cytodifferentiation of bovine myocytes by competitively combining with miR-199a-5p and miR-433 to activate the mitogen-activated protein kinase kinase kinase 11 (MAP3K11)/mitogen-activated protein kinase kinase 7 (MAP2K7)/JNK signaling pathway.

Abstract
MicroRNAs (miRNAs) are essential factors in the reproductive process of poultry. Here, we found miR-302d is a potential differentiation and negative factor of chicken embryonic stem cells (ESCs) into spermatogonia stem cells (SSCs). The competition mechanism was carried out for the preliminary exploration to determine the relationship among miR-302d, lncRNA-341(interacting with miR-302d), and target gene TLE4. The results showed that lncRNA-341 can competitively bind to miR-302d to decrease the targeted binding of miR-302d and TLE4 which promotes the differentiation of chicken SSCs. Moreover, it is suggested that miR-302d may participate in the Wnt signaling pathway through TLE4.

Abstract
BACKGROUND Growth performance is significant in broiler production. In the growth process of broilers, gene expression varies at different growth stages. However, limited research has been conducted on the molecular mechanisms of muscle growth and development in yellow-feathered male chickens. RESULTS In the study, we used RNA-seq to study the transcriptome of the breast muscle of male Jinghai yellow chickens at 4 (M4F), 8 (M8F) and 12 weeks (M12F) of age. The results showed that 4608 differentially expressed genes (DEGs) were obtained by comparison in pairs of the three groups with Fold Change (FC) ≥ 2 and False Discovery Rate (FDR) ≤ 0.05, and 83, 3445 and 3903 DEGs were obtained separately from M4FvsM8F, M4FvsM12F and M8FvsM12F. Six genes were found as co-differentially expressed in the three age groups, namely SNCG, MYH1A, ARHGDIB, ENSGALG00000031598, ENSGALG00000035660 and ENSGALG00000030559. The GO analysis showed that 0, 304 and 408 biological process (BP) were significantly enriched in M4FvsM8F, M4FvsM12F and M8FvsM12F groups, respectively. KEGG pathway enrichment showed that 1, 2, 4 and 4 pathways were significantly enriched in M4FvsM8F, M4FvsM12F, M8FvsM12F and all DEGs, respectively. They were steroid biosynthesis, carbon metabolism, focal adhesion, cytokine-cytokine receptor interaction, biosynthesis of amino acids and salmonella infection. We constructed short hairpin RNA (shRNA) to interfere the differentially expressed gene RAC2 in DF-1 cells and detected mRNA and protein expression of the downstream genes PAK1 and MAPK8. Results of qPCR showed that RAC2, PAK1 and MAPK8 mRNA expression significantly decreased in the shRAC2-2 group compared with the negative control (NC) group. Western Blot (WB) results showed that the proteins of RAC2, PAK1 and MAPK8 also decreased in the shRAC2-2 group. Cell Counting Kit-8 (CCK-8) and 5-Ethynyl-2'-deoxyuridine (EdU) assay both showed that the proliferation of DF-1 cells was significantly inhibited after transfection of shRAC2-2. CONCLUSIONS The results of RNA-seq revealed genes, BP terms and KEGG pathways related to growth and development of male Jinghai yellow chickens, and they would have important guiding significance to our production practice. Further research suggested that RAC2 might regulate cell proliferation by regulating PAKs/MAPK8 pathway and affect growth of chickens.

Abstract
Long noncoding RNAs (lncRNAs) participate in the formation of primordial germ cells (PGCs); however, the identity of the key lncRNAs and the molecular mechanisms responsible for the formation of PGCs remain unknown. Here, we identify a key candidate lncRNA (lncRNA PGC transcript-1, LncPGCAT-1) via RNA sequencing of embryonic stem cells, PGCs, and Spermatogonial stem cells (SSCs). Functional experiments confirmed that LncPGCAT-1 positively regulated the formation of PGCs by elevating the expression of Cvh and C-kit while downregulating the pluripotency(Nanog) in vitro and in vivo; PAS staining of genital ridges in vivo also showed that interference with LncPGCAT-1 can significantly reduce the number of PGCs in genital ridges, while overexpression of LncPGCAT-1 had the opposite result. The result of luciferase reporter assay combined with CHIP-qPCR showed that the expression of LncPGCAT-1 was promoted by the transcription factor P53 and high levels of H3K4me2. Mechanistically, the luciferase reporter assay confirmed that mitogen-activated protein kinase 1 (MAPK1) was the target gene of LncPGCAT-1 and gga-mir-1591. In the ceRNA system, high levels of N6 methylation of LncPGCAT-1 enhanced the adsorption capacity of LncPGCAT-1 for gga-mir-1591. Adsorption of gga-mir-1591 activated the MAPK1/ERK signaling cascade by relieving the gga-mir-1591-dependent inhibition of MAPK1 expression. Moreover, LncPGCAT-1 interacted with interleukin enhancer binding factor 3 (ILF3) to regulate the ubiquitination of P53 and phosphorylation of JNK. Interaction with ILF3 resulted in positive self-feedback regulation of LncPGCAT-1 and activation of JNK signaling, ultimately promoting PGC formation. Altogether, the study expands our knowledge of the function and molecular mechanisms of lncRNAs in PGC development.
