Female GFP growth varies significantly, however, the processes responsible for these growth disparities remain unknown. In this study, intestinal and hemolymph samples of large (FL), medium (FM), and small (FS) female GFPs were collected to investigate the molecular mechanism of female GFP growth. Through the utilization of 16S rRNA sequencing and liquid chromatography-mass spectrometry metabolomics, significant intestinal flora and metabolites linked to the growth performance of female GFPs were identified. The dominant phyla of the three groups were the same, namely Firmicutes and Proteobacteria. Among groups, small females exhibited the lowest abundance of Proteobacteria (27.26 %) and the highest abundance of Firmicutes (70.10 %). The most abundant genus in each group was <em>Lactococcus</em>. Liquid chromatography-mass spectrometry identified 115 annotated differential metabolites, and essential metabolites related to female GFP growth performance were screened. The concentration of serum metabolites in the larger females exhibited a statistically significant variance compared to that of the smaller females. Through association analysis, we identified key genes, metabolites, and gut microbiota that influence the growth of female GFPs. Likewise, we used multi-omics techniques to establish two relationship models (“gut microbiota-GFP phenotype-metabolite”, “gut microbiota-GFP phenotype-transcript”), and three important network association models (“DN5520_c0_g1-CW1-Bacteroides”, “DN537746_c0_g1-BW-<em>Roseburia</em>” and “Picolinic acid-phenotype-<em>Roseburia</em>”) were further developed.

The ivory shell, <em>Babylonia areolata</em>, plays a crucial role in marine aquaculture as a widely distributed mollusk in tropical and subtropical seas. However, limited research has been conducted on its molecular mechanisms in response to heat stress. This study aims to explore thermal-tolerant related genes and regulatory pathways by constructing a cDNA library under heat stress and using a yeast-based high-throughput screening method. Following exposure of three populations to acute heat stress, a heat stress cDNA library was constructed with a capacity of 1.104 × 10<sup>8</sup>, containing 2.208 × 10<sup>8</sup> clones. Subsequently, the library was transformed into yeast INVSc1 and underwent high-temperature screening at 39 °C. All positive clones were then subjected to next-generation sequencing (NGS) for rapid identification of 1148 candidate genes associated with thermal tolerance. Enrichment analysis revealed that these genes were significantly enriched in seven KEGG pathways, including Protein processing in endoplasmic reticulum, Ribosome and Ubiquitin mediated proteolysis. Additionally, through first-generation sequencing of 96 randomly selected positive clones at 39 °C, we identified 51 unique sequences associated with heat stress which included previously reported genes like <em>EEF2</em>, <em>HSPB1</em>, <em>UBC</em> and <em>HSPA4</em>. Subsequent yeast heat tolerance experiments further validated the essential role played by these 51 genes in response to thermal stress conditions. Finally, RNA-seq data provided evidence for upregulated expression levels of these genes during exposure to elevated temperatures. This study successfully constructed the first cDNA library for <em>B. areolata</em> under heat stress conditions, identified key pathways and candidate genes associated with thermal tolerance, and demonstrated the applicability of yeast high-throughput screening methods in investigating stress resistance traits in invertebrates.

In order to elucidate the protein components of the coelomic fluid and investigate its immune response mechanism, proteomic analysis and antimicrobial characterization of the coelomic fluid of <em>U. unicinctus</em> were carried out. A total of 2194 proteins were identified, with 427 showing differential expression in coelomocytes compared to those in the coelomic fluid supernatant. Of these proteins, 346 were upregulated and 81 were downregulated. Next, these identified proteins were analyzed for biological information, including GO, COG, and KEGG pathway analysis. The results from the GO analysis revealed that cytoplasm and ATP-binding were the two prominent categories of proteins found in the coelomocytes as well as the coelomic fluid supernatant of <em>U. unicinctus</em>. From the COG analysis, it was evident that the categories of proteins identified in the coelomocytes were essentially the same as those identified in the coelomic fluid supernatant, with only the number of proteins differing. The KEGG pathway analysis indicated that 45 pathways from the coelomic fluid supernatant and 42 from the coelomocytes were profiled, with carbon metabolism and ribosome being the two most prominent pathways. The Pfam database displayed that the immune-related proteins in <em>U. unicinctus</em> were neurofascin, cell adhesion molecule 4, receptor-type tyrosine-protein phosphatase F, limbic system-associated membrane protein, four and a half LIM domains protein 2, neuroglian, fasciclin-2, and neural cell adhesion molecule.

The study of liver gene expression, changes in metabolic products and the regulation of gut microbial communities in plateau animals under harsh environments can reveal the mechanisms by which Tibetan goats adapt to the plateau environment. This study employs transcriptome, metabolome and metagenomic analyses to reveal the differences in genes, metabolism, and gut microbiota between Jianzhou big-eared goats (JBG) and Xizang cashmere goats (TCG), which is of significant importance for improving survival models of high-altitude ruminants. The results showed that there were 553 DEGs in the liver of JBG and TCG. Hepatic metabolomic analysis revealed significant differences in metabolic activity between the JBG and TCG groups, with notable increases in glycerophospholipid and retinol metabolic pathways. The gut microbiota, including <em>Andreesenia</em>, <em>Dielma</em>, <em>Oscillibacter</em>, <em>Agrobacterium</em>, <em>Hyella</em> and <em>Th</em>ermosinus, interact with liver metabolites and can regulate the high-altitude adaptability of goats. This study reveals that TCG enhance immune regulation and energy utilization efficiency by regulating liver gene expression, modulating metabolic pathways, and improving gut microbiota, thereby helping TCG maintain healthy survival capabilities in hypoxic and high-radiation environments.</div></div>","PeriodicalId":55235,"journal":{"name":"Comparative Biochemistry and Physiology D-Genomics & Proteomics","volume":"54 ","pages":"Article 101422"},"PeriodicalIF":2.2,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026069","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}
