Li H, Jiang X, Zhang S, Li Y, Wang X, Liang J. MiR-214_L-1R+4 regulate gossypol-induced immune response through MyD88-dependent signaling pathway in Cyprinus carpio. FISH & SHELLFISH IMMUNOLOGY 2024; 151:109744. [PMID: 38960107 DOI: 10.1016/j.fsi.2024.109744] [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: 03/21/2024] [Revised: 06/30/2024] [Accepted: 07/01/2024] [Indexed: 07/05/2024]
Abstract
MicroRNAs (miRNAs) have been demonstrated to act as crucial modulators with considerable impacts on the immune system. Cottonseed meal is often used as a protein source in aqua feed, cottonseed meal contains gossypol, which is harmful to animals. However, there is a lack of research on the role of miRNAs in fish exposed to gossypol stress. To determine the regulatory effects of miRNAs on gossypol toxicity, Cyprinus carpio were given to oral administration of 20 mg/kg gossypol for 7 days, and the gossypol concentration in the tissues was tested. Then, we detected spleen index, histology, immune enzyme activities of fish induced by gossypol. The results of miRNA sequencing revealed 8 differentially expressed miRNAs in gossypol group, and miR-214_L-1R+4 was found involved in immune response induced by gossypol. The potential targets of miR-214_L-1R+4 were predicted, and found a putative miR-214_L-1R+4 binding site in the 3'UTR of MyD88a. Furthermore, dual-luciferase reporter assays displayed miR-214_L-1R+4 decreased MyD88a expression through binding to the 3'UTR of MyD88a. Moreover, miR-214_L-1R+4 antagomir were intraperitoneally administered to C. carpio, down-regulated miR-214_L-1R+4 could increase MyD88a expression, as well as inflammatory cytokines and anti-inflammatory cytokines expression. These findings revealed that miR-214_L-1R+4 via the MyD88-dependent signaling pathway modulate the immune response to gossypol in C. carpio spleen.

Niu H, Hao Y, Pang Y, Shen Y, Li J, Xu X. LncRNA-adm2 targets adm2 via cid-miR-n3 and negatively regulates the inflammatory response in grass carp (Ctenopharyngodon idella). FISH & SHELLFISH IMMUNOLOGY 2023; 138:108800. [PMID: 37187213 DOI: 10.1016/j.fsi.2023.108800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 04/23/2023] [Accepted: 05/05/2023] [Indexed: 05/17/2023]
Abstract
Long non-coding RNAs (lncRNAs), which impact gene expression following pathogen infections, have garnered significant attention in recent years. Recent discoveries have revealed that lncRNAs play a crucial role in fish immune responses to pathogen infections. We investigated the influence of lncRNA-adm2 on the antibacterial immune response generated by Aeromonas hydrophila in grass carp (Ctenopharyngodon idella) through the adsorption of cid-miR-n3. Furthermore, we found that cid-miR-n3 interacts with lncRNA-adm2 and targets the 3' UTR of adm2. The upregulation of lncRNA-adm2 expression led to the suppression of pro-inflammatory cytokines (il-1β and il-6) in CIK cells, while anti-inflammatory cytokines (il-10) increased. Our research provides evidence that lncRNAs are involved in the antibacterial immune response of fish, expanding our understanding of the function of lncRNAs in teleosts.
