[PMID: 38801841 DOI: 10.1016/j.fsi.2024.109658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 05/09/2024] [Accepted: 05/24/2024] [Indexed: 05/29/2024]
Abstract
microRNAs are a class of non-coding RNAs with post-transcriptional regulatory functions in eukaryotes. In our previous study, miR-184-3p was identified in the hemocyte transcriptome of Pinctada fucata martensii (Pm-miR-184-3p), and its expression was shown to be up-regulated following transplantation surgery; however, its role in regulating transplantation immunity has not yet been clarified. Here, the role of Pm-miR-184-3p in regulating the immune response of P. f. martensii was studied. The expression of Pm-miR-184-3p increased following the stimulation of pathogen-associated molecular patterns, and Pm-miR-184-3p overexpression increased the activity of antioxidant-related enzymes, such as superoxide dismutase and catalase. Transcriptome analysis obtained 1096 differentially expressed genes (DEGs) after overexpression of Pm-miR-184-3p, and these DEGs were significantly enriched in conserved pathways such as the Cell cycle pathway and NF-kappa B signaling pathway, as well as GO terms including base excision repair, cell cycle, and DNA replication, suggesting that Pm-miR-184-3p could enhance the inflammation process. Target prediction and dual luciferase analysis revealed that pro-inflammatory related genes Pm-TLR3 and Pm-FN were the potential target of Pm-miR-184-3p. We speculate that Pm-miR-184-3p may utilize negative regulation of target genes to delay the activation of corresponding immune pathways, potentially preventing excessive inflammatory responses and achieving a delicate balance within the organism. Overall, Pm-miR-184-3p play a key role in regulating cellular responses to transplantation. Our findings provide new insights into the immune response of P. f. martensii to transplantation.

Hou Y, Liao T, Zhang F, Zhang T, Wang L, Lv W, Li Z. MicroRNA transcriptome analysis reveals the immune regulatory mechanism of Crassostrea hongkongesis against Vibrio harveyi infection. FISH & SHELLFISH IMMUNOLOGY 2024; 145:109354. [PMID: 38171431 DOI: 10.1016/j.fsi.2023.109354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 12/21/2023] [Accepted: 12/29/2023] [Indexed: 01/05/2024]
Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that modulate target-genes expression and play crucial roles in post-transcriptional regulation and immune system regulation. The Hong Kong oyster (Crassostrea hongkongesis), as the main marine aquaculture shellfish in the South China Sea, not only has high economic and ecological value, but also is an ideal model for conducting research on pathogen host interaction. Vibrio harveyi, a Gram negative luminescent marine bacterium, is widely distributed in coastal water environments and can cause large-scale death of C. hongkongesis. However, little in formation is available on the immune regulatory mechanisms of C. hongkongesis infected with V. harveyi. Therefore, we performed microRNA transcriptome analysis for elucidating the immunoregulation mechanism of C. hongkongesis infected with V. harveyi. The results show that a total of 308468208 clean reads and 288371159 clean tags were obtained. 222 differentially expressed miRNAs were identified. A total of 388 target genes that were differentially expressed and negatively correlated with miRNA expression were predicted by 222 DEmiRs. GO enrichment analysis of 388 DETGs showed that they were mainly enriched in the immune-related term of membrane-bounded vesicle, endocytic vesicle lumen, antigen processing and presentation of exogenous peptide antigen via MHC class I, antigen processing and presentation of peptide antigen via MHC class I, and other immune-related term. KEGG enrichment analysis showed that DETGs were mainly enriched in the Complement and coagulation cascades, Herpes simplex virus 1 infection, Bacterial invasion of epithelial cells, Antigen processing and presentation and NOD-like receptor signaling pathway. The 16 key DEmiRs and their target genes form a regulatory network for seven immune-related pathways. These results suggest that V. harveyi infection induces a complex miRNA response with wide-ranging effects on immune gene expression in the C. hongkongesis. This study explored the immune response of C. hongkongesis to V. harveyi infection at the level of miRNAs, which provides new ideas for the healthy culture and selective breeding of C. hongkongesis.

Molecular mechanisms that regulate the heat stress response in sea urchins (Strongylocentrotus intermedius) by comparative heat tolerance performance and whole-transcriptome RNA sequencing. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 901:165846. [PMID: 37541492 DOI: 10.1016/j.scitotenv.2023.165846] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 06/07/2023] [Accepted: 07/26/2023] [Indexed: 08/06/2023]
Abstract
In the context of climate change and extreme high temperature, the commercially important sea urchin Strongylocentrotus intermedius suffers high mortality during summer in Northern China. How sea urchins respond to high temperatures is of great concern to academia and industry. How to understand the heat tolerance of sea urchin from the whole transcriptome level. In this study, the heat-resistant S. intermedius bred by our team and its control group were used as the research objects, then we applied whole-transcriptome RNA sequencing to detect differentially expressed mRNAs, microRNAs, long noncoding RNAs that respond to heat stress in the heat-resistant and control S. intermedius. A competitive endogenous RNA (ceRNA) regulatory network was constructed with predicted pairs of differentially expressed mRNAs and noncoding RNAs and revealed the molecular regulatory mechanisms in S. intermedius responding to heat stress. A functional analysis suggested that the ceRNAs were involved in basal metabolism, calcium ion transport, endoplasmic reticulum stress, and apoptosis. This is the whole-transcriptomic analysis of S. intermedius under heat stress to propose ceRNA networks that will provide a basis for studying the potential functions of long noncoding RNAs and miRNAs in the heat stress response in S. intermedius and provide a theoretical basis for the study of the molecular mechanism of sea urchins in response to environmental changes.

FISH & SHELLFISH IMMUNOLOGY 2023; 142:109120. [PMID: 37813153 DOI: 10.1016/j.fsi.2023.109120] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 09/15/2023] [Accepted: 09/27/2023] [Indexed: 10/11/2023]
Abstract
The Hong Kong oyster (Crassostrea hongkongesis), as the main marine aquaculture shellfish in the South China Sea, not only has high economic and ecological value, but also is an ideal model for conducting research on pathogen host interaction. However, diseases caused by Vibrio pose a serious impediment to the culture of C. hongkongesis. In this study, we performed transcriptome analysis of digestive diverticula of C. hongkongesis infected with V. harveyi. A total of 977, 689, 912 high quality reads and 955, 208, 562 valid reads were obtained. At 12, 24, 48 and 72 h post-infection, 1402, 2168, 2727 and 1398 differentially expressed genes (DEGs) were captured, respectively. GO enrichment analysis showed that DEGs were significantly enriched in cellular processes, catalytic activity, cell part and other terms. KEGG enrichment analysis revealed that these DEGs were mainly closely related to Necroptosis, RIG-I-like receptor signaling pathway, NF-kappa B signaling pathway, Toll-like receptor signaling pathway and other pathways are related. The results of WGCNA analysis indicated that THBS1, CA10, Trpm2, THAP12, PTPRT, HSPA12A, and ADAM10 were the hub genes in the gene co-expression network. This study will provide new ideas at the transcriptome level for the immune regulatory mechanisms and adaptability of the C. hongkongesis to V. infection, as well as for achieving selective breeding for Vibrio resistance in the C. hongkongesis.
