Environmental conditions in the Pacific white shrimp did not found to affect genetic sex determination (ZZ/ZW system). The androgenic gland (AG)-secreting insulin-like androgenic gland hormone (IAG) is a key controlling factor in crustacean male differentiation. However, functional sex reversal (neo-male) in penaeid shrimp has not yet been achieved by manipulating the IAG-sexual switch. Therefore, understanding the molecular mechanisms of gonadal differentiation may help build appropriate tools to generate neo-male (ZW) for all-female breeding. This study describes the potential role of the novel penaeid-specific testicular zinc finger protein (pTZFP) in the gonads of Pacific white shrimp. First, pTZFP transcripts show a male-bias expression pattern in undifferentiated gonads, which is then exclusively expressed in the testis and absent or slightly expressed in the ovary and other tissues. Besides, the knockdown of pTZFP in undifferentiated males results in smaller testes but no sex reversal. Immunohistochemical (IHC) staining of proliferating cell nuclear antigen (PCNA) further confirmed that the smaller testes in pTZFP-deficient males are due to the lower proliferating activity of spermatogonia. These data reveal that pTZFP may be involved in testicular development but have fewer effects on gonadal differentiation. Moreover, testicular pTZFP transcription levels were not reduced with estradiol-17β (E2) administration or AG excision. Therefore, our data suggest that pTZFP may regulate testicular development through downstream genes regulating spermatogonia proliferation. Moreover, our data provide an appropriate molecular marker for identifying the sex of undifferentiated gonads.</p>","PeriodicalId":8965,"journal":{"name":"Biology of Reproduction","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142457234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multivariate analyses (OPLS-DA) were conducted to compare the metabolomic signatures of oviductal fluids. Correlation network analysis was conducted to measure the strength and hierarchy of associations among metabolites. Of the 205 metabolites quantified, 171 were detected in at least 50% of the samples and were included in further data analysis.

Twenty metabolites had different or tended to have different concentrations in the oviductal fluid when comparing groups. Seven of these 20 analytes had greater concentrations in LF cows. Moreover, total sum of biogenic amines, phosphatidylcholines, and prostaglandins were higher in the SF group.

In this study, placental expression of both YAP1 and CCN1 was found to be impaired in pregnancies complicated by early-onset severe preeclampsia. CCN1 was expressed not only in cytotrophoblasts, trophoblast columns, and mesenchymal cells, similar to active YAP1, but also in syncytiotrophoblasts of normal first-trimester placental villi; moreover, decidual staining of active YAP1 and CCN1 was found in both interstitial and endovascular extravillous trophoblasts. In cultured immortalized human trophoblastic HTR-8/SVneo cells, knockdown of YAP1 decreased CCN1 mRNA and protein expression and led to impaired cell invasion and migration. Also, CCN1 knockdown negatively affected HTR-8/SVneo cell invasion and migration but not viability. YAP1 knockdown was further found to impair HTR-8/SVneo cell viability via G0/G1 cell cycle arrest and apoptosis, while CCN1 knockdown had minimal effect on cell cycle arrest and no effect on apoptosis. Accordingly, treatment with recombinant CCN1 partially reversed the YAP1 knockdown-induced impairment in trophoblast invasion and migration but not in viability.

Transcriptome profiling identified three types of oocytes (small, medium, and large) that underwent different developmental trajectories, with large oocytes exhibiting the largest average follicle size and characteristics resembling metaphase-II oocytes. Differential expression analysis and real-time polymerase chain reaction assay showed that most replication-dependent histone genes were highly expressed in large oocytes. The joint analysis of multi-omics data revealed that the transcription of 20 differentially expressed genes in large oocytes was associated with both DNA methylation and chromatin accessibility. In addition, oocyte-cumulus interaction analysis showed that inflammation, DNA damage, and p53 signaling pathways were active in small oocytes, which had the smallest average follicle sizes. We further confirmed that p53 pathway inhibition in the in vitro maturation experiments using oocytes obtained from small antral follicles could improve the quality of oocytes and increased the blastocyte rate after in vitro fertilization and culture.

Interleukin-32 expression was quantified via polymerase chain reaction and immunohistochemistry, and functional assays were performed after interleukin-32 modulation. Interleukin-32 was identified only in placental mammals, such as Carnivora, Cetartiodactyla, Chiroptera, Dermoptera, Lagomorpha, Perissodactyla, and Primates via bioinformatics.

The incidence of PE is steadily rising, posing a significant threat to the lives of both the pregnant woman and the fetus. Most studies on PE pathogenesis currently focus on the placenta, but maternal decidualization forms the foundation for placental growth and development. Recent studies have shown that impaired decidualization is also a cause of PE. Decidualization is a process where endometrial stromal cells gradually transform into secretory decidual cells during early pregnancy. While NSUN5 encodes a member of a conserved family of proteins, its role in pregnancy remains unknown. In this study, we conducted experiments and observed a significant downregulation of NSUN5 expression in severe PE decidual tissues compared to those of normal pregnant women. When inducing decidualization in vitro, we found an increase in NSUN5 expression. However, when we used siRNA to knockdown NSUN5 expression, the process of decidualization was prevented. Moreover, we observed a decrease in ATP content during both cell decidualization and after knockdown of NSUN5. Finally, through immunoprecipitation combined with mass spectrometry, we discovered that the protein ATP5B interacts with NSUN5. Furthermore, after knocking down ATP5B using siRNA, we observed impaired decidualization. Moreover, transfection with siRNA to suppress NSUN5 resulted in a decrease in ATP5B expression.
