Summary: In this study, we identified 27 ChemR genes in miiuy croaker and analyzed their characteristics, including gene structure, evolutionary mechanism, and expression levels upon bacterial infection. The results showed that these genes underwent tandem and segmental duplication events during evolution, and teleost fishes' ChemRs may have a higher evolutionary dynamic compared to vertebrates. Additionally, 21 positively selected codons were detected in vertebrate ChemRs under Model 8, and certain genes were significantly up-regulated upon Vibrio harveyi infection, providing valuable information for further functional analysis.

Summary: In recent years, there has been an increasing focus on the study of circular RNAs (circRNAs) in noncoding RNAs. While circRNAs are abundant in mammalian studies, research in lower vertebrates has been lacking. In this study, a circRNA called circPlce1 was found to be related to the innate immune response in Miichthys miiuy (miiuy croaker). Experimental results showed that circPlce1 could promote the production of antiviral genes and inflammatory response. It was also observed that circPlce1 can promote cell proliferation and improve cell viability. The study provides a foundation for understanding the biological function of circRNAs in the innate immune response in teleost fish.

Summary: With the in-depth study of circRNA, its important role in mammals, such as cell proliferation, apoptosis, invasion, development, and disease state, has been demonstrated. However, the regulatory mechanism of circRNA in lower vertebrates remains unclear. In this study, a new circRNA named circRara was identified and its positive regulatory effect on the antiviral and antibacterial response, cell proliferation, and activity in miiuy croaker was confirmed.

Summary: In this study, a novel NLRC3-NLRP12 fusion gene was identified in the miiuy croaker. The fusion gene was significantly upregulated after infection with V. anguillarum or stimulation with LPS, and its overexpression inhibited NF-kappa B activation. These findings suggest that the newly discovered NLRC3-NLRP12 fusion gene may play an important role in innate immunity in miiuy croaker.

Summary: In this study, Vclb was found to inhibit the NF-KB signaling pathway, and its inhibitory effect was enhanced by LPS induction. Furthermore, Vclb inhibits NF-KB activation by targeting MyD88, thereby suppressing the production of inflammatory cytokines. Mechanistically, Vclb inhibits the NF-KB signaling pathway by targeting MyD88 ubiquitin-proteasome pathway.

Summary: This study identified a novel long noncoding RNA (lncRNA) called LTCONS6801 in Miichthys miiuy, which contributes to the TANK-binding kinase 1 (TBK1) pathway and promotes the host immune function. The overexpression of lncRNA LTCONS6801 was found to enhance cell activity and increase the expression of antiviral genes and TBK1. Furthermore, lncRNA LTCONS6801 was found to regulate the NF-kappa B and IRF3 signaling pathways by modulating TBK1 expression. In conclusion, lncRNA LTCONS6801 positively regulates the host innate immune response by controlling TBK1 expression, highlighting its important role in antiviral immunity of teleost fish.

Summary: Alternative splicing is an important mechanism for controlling gene expression in eukaryotes. This study identified three different splicing isoforms in the ferritin gene fthl27 of Miichthys miiuy and found that they showed an upregulation trend after stimulation. These isoforms may have different regulatory effects on inflammatory factors and antiviral immune factors, playing a significant role in the innate immune response of fish.

Summary: This study identified METTL16 in miiuy croaker and found that its expression was increased after poly(I:C) stimulation, suggesting its involvement in antiviral immunity. Functional experiments showed that mmiMETTL16 could inhibit immune response caused by viral stimulation. Overall, the study on mmiMETTL16 will contribute to understanding the role of METTL16 in the teleost immune system and the potential mechanisms of the m6A regulation network.
