[PMID: 38792700 PMCID: PMC11124158 DOI: 10.3390/microorganisms12050871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/19/2024] [Accepted: 04/23/2024] [Indexed: 05/26/2024] Open
Abstract
The blotched snakehead Channa maculata is an important economical freshwater species in East Asia. However, there has been relatively little research conducted on the correlation between gender and gut microbes. In this study, 36 of 1000 blotched snakeheads were randomly selected for growth performance measurement and gut microbiota high-throughput sequencing. Results showed that microbial diversity, composition, and metabolic functions were altered by gender and growth performance except the microbial network. In our study, Proteobacteria were the most abundant phylum, with Fusobacteria showing enrichment in males and Bacteroidetes in females. Notably, phylum Deinococcus-Thermus was identified as a significant biomarker. The Cetobacterium was the most abundant genus-level taxon. Furthermore, gut microbes specializing in the production of gut-healthy substances, such as coenzymes and vitamins, were identified as biomarkers in the fast-growing group. Our investigation highlighted the impact of gender on the composition and abundance of gut microbial biomarkers in both males and females, thereby influencing differential growth performance through the modulation of specific metabolic functions.

FISH & SHELLFISH IMMUNOLOGY 2023; 135:108653. [PMID: 36868540 DOI: 10.1016/j.fsi.2023.108653] [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: 09/22/2022] [Revised: 02/26/2023] [Accepted: 02/28/2023] [Indexed: 06/18/2023]
Abstract
Echinacea purpurea (Linn.) Moench (EP) is a globally popular herbal medicine, which showed effects on growth promotion, antioxidant and immunomodulatory activities in fish culture world widely. However, there are few studies about the effects on miRNAs by EP in fish. The hybrid snakehead fish (Channa maculate♀ × Channa argus ♂) was new important economic specie of freshwater aquaculture in China with high market value and demand while there were only a few reports about its miRNAs. To overview immune-related miRNAs of the hybrid snakehead fish and to further understand the immune regulating mechanism of EP, we herein constructed and analyzed three small RNA libraries of immune tissues including liver, spleen and head kidney of the fish with or without EP treatment via Illumina high-throughput sequencing technology. Results showed that EP can affect the immune activities of fish by the miRNA-regulated ways. Totally, 67 (47 up and 20 down) miRNAs in liver, 138 (55 up and 83 down) miRNAs in spleen, and 251 (15 up and 236 down) miRNAs in spleen were detected, as well as 30, 60, 139 kinds of immune-related miRNAs belonging to 22, 35 and 66 families of the three tissues respectively. The expressions of 8 immune-related miRNA family members were found in all the three tissues, including miR-10, miR-133, miR-22 and etc. Some miRNAs have been identified involved in the innate and adaptive immune responses, such as the miR-125, miR-138, and miR-181 family. Ten miRNA families with antioxidant target genes were also discovered, including miR-125, miR-1306, and miR-138, etc. Results from Gene Ontology (GO) and KEGG pathway analysis further confirmed there are a majority immune response targets of the miRNAs involved in the EP treatment process. Our study deepened understanding roles of miRNAs in fish immune system and provides new ideas for the study of immune mechanism of EP.
