Abstract
Inadequate gonadal maturation and poor spawning performance increasingly threaten the sustainability of shrimp aquaculture. Unraveling the mechanisms regulating ovarian development and maturation hence is critical to address industry challenges. Vitellogenin (Vtg), a precursor of yolk protein found in the hepatopancreas and ovary of shrimp, plays a key role in facilitating shrimp's oocyte maturation and embryonic development after oviposition. This study found that FpVtg was specifically expressed in F. penicillatus hepatopancreas and ovary. FpVtg was localized predominantly in the oocyte cytoplasm and distributed uniformly in the hepatopancreas tissue. Silencing FpVtg led to apoptosis in both hepatopancreas and ovary tissues. Furthermore, FpVtg depletion upregulated the expression of ovarian peritrophin 1, ovarian peritrophin 2, serine proteinase inhibitor 6, and juvenile hormone esterase-like carboxylesterase 1, while downregulated that of vitellogenin, delta-9 desaturase, and insulin-like receptor. KEGG pathway analysis implicated such as PI3K-AKT signaling, RNA transport, ECM-receptor interaction, hippo signaling, oocyte meiosis, and apoptosis were enriched and involved in ovarian development. These findings have provided insights into the FpVtg's reproductive role and the associated regulatory genes and pathways in F. penicillatus. This knowledge can contribute to establishing strategies to improve the breeding and aquaculture production of F. penicillatus by elucidating its vitellogenesis regulation in redtail prawn and other penaeid species. Further characterization of the implicated pathways and genes will clarify the intricacies underlying ovarian maturation.

Abstract
Nuclear factor-kappa B (NF-κB) pathways have a close relationship with many diseases, especially in terms of the regulation of inflammation and the immune response. Non-coding RNAs (ncRNAs) are a heterogeneous subset of endogenous RNAs that directly affect cellular function in the absence of proteins or peptide products; these include microRNAs (miRNAs), long noncoding RNAs (lncRNAs), circular RNAs (circRNAs), etc. Studies on the roles of ncRNAs in targeting the NF-κB pathways in aquatic animals are scarce. A few research studies have confirmed detailed regulatory mechanisms among ncRNAs and the NF-κB pathways in aquatic animals. This comprehensive review is presented concerning ncRNAs targeting the NF-κB pathway in aquatic animals and provides new insights into NF-κB pathways regulatory mechanisms of aquatic animals. The review discusses new possibilities for developing non-coding-RNA-based antiviral applications in fisheries.

Abstract
Penaeus vannamei is the most economically important species of shrimp cultured worldwide. Enterocytozoon hepatopenaei (EHP) is an emerging pathogen that severely affects the growth and development of shrimps. In this study, the transcriptome differences between EHP-infected and uninfected shrimp were investigated through next-generation sequencing. The unigenes were assembled with the reads from all the four libraries. The differentially expressed genes (DEGs) of intestines and hepatopancreas were analyzed. There were 2,884 DEGs in the intestines and 2,096 DEGs in the hepatopancreas. The GO and KEGG enrichment analysis indicated that DEGs were significantly enriched in signaling pathways associated with nutritional energy metabolism and mobilizing autoimmunity. Moreover, the results suggested the downregulation of key genes in energy synthesis pathways contributed greatly to shrimp growth retardation; the upregulation of immune-related genes enhanced the resistance of shrimp against EHP infection. This study provided identified genes and pathways associated with EHP infection revealing the molecular mechanisms of growth retardation.

Abstract
The study was conducted to evaluate the effects of fish oil replacement by vegetable oils on growth performance, histology, and antioxidant capacity of Macrobrachium rosenbergii. Three isonitrogenous and isoenergetic diets were formulated with different lipid sources included. DFO diet contained 6% fish oil, whereas DSO and DRO diets included 6% soybean oil and rapeseed oil (RO) as alternatives for fish oil, respectively. Prawns were fed thrice daily for 8 weeks. The results showed that prawns in DFO group showed significantly lower final weight, weight gain ratio, and specific growth rate (SGR), but higher feed intake and feed coefficient ratio than those in DSO and DRO groups. In hepatocellular ultrastructure, malformed and atrophic nucleus and higher apoptosis ratio were observed in DFO group. In addition, levels of haemolymph proinflammatory cytokines, activities of anti-superoxide anion, inducible-type NO-synthase (iNOS) and content of nitric oxide, and hepatopancreas NF-κB signal pathway gene expression in DFO group increased markedly compared to those of DSO and DRO groups. The results suggested that vegetable oils, such as soybean oil and RO might be the better lipid sources in diets for Macrobrachium rosenbergii than fish oil, it may be attributed to modified oxidative status induced by NF-κB-NO signal pathway.

Abstract
Peroxinectin with cell adhesion and peroxidase activities plays an important role in innate immune responses of invertebrate. In the study, the full-length cDNA of a peroxinectin homolog (FpPX) was identified from Fenneropenaeus penicillatus. The full-length cDNA of FpPX is 2573 bp long, with an open reading frame (ORF) encoding a putative protein of 780 amino acids, including a peroxidase domain and a KGD motif. FpPX shared 65-96% similarities with other crustaceans peroxinectin proteins. Real-time quantitative RT-PCR indicated that FpPX was constitutively expressed in gill, heart, hemocytes and muscle of F. penicillatus. The temporal expression patterns of FpPX mRNA were different in the various tissues after microbial challenge. FpPX expression levels were significantly upregulated in gill, hemocytes and muscle after white spot syndrome baculovirus (WSSV) or Vibrio alginolyticus injection. Conversely, FpPX expression in the heart maintained at a low level and showed no obvious changes at any of the tested time points. The results of RNAi experiment showed that silencing FpPX could inhibit prophenoloxidase expression in vivo, and lead to a significantly higher mortality of shrimps after WSSV or V. alginolyticus challenge, suggesting FpPX is required in defense against bacterial and viral pathogens. In conclusion, these data revealed that FpPX played an important role in immune response of F. penicillatus against pathogenic infection.

Abstract
Lysozyme is an important defense molecule of the innate immune system and possess high antimicrobial activities. In this study, a full-length c-type lysozyme cDNA (Fplysc) was cloned and characterized from Fenneropenaeus penicillatus. The cDNA contains an open reading frame of 477 bp encoding 158 amino acids, with 53-94% identity with those of other crustaceans. The recombinant Fplysc had antibacterial activities against Gram-positive bacteria (Streptococcus agalactiae and Micrococcus luteus) and Gram-negative bacteria (Vibrio alginolyticus and Escherichia coli), and showed antiviral activity against WSSV and IHHNV. The qRT-PCR analysis showed that Fplysc expression levels were most abundant in hemocytes and less in eyestalk. The expression levels of Fplysc were significantly upregulated in gill, intestine and hemocytes when challenged with WSSV and V. alginolyticus. Fplysc-silencling suppressed Fplysc expression in cephalothoraxes and increased mortality caused by WSSV and V. alginolyticus, and exogenous rFplysc led to a significant decrease of shrimp mortality by injecting rFplysc into Fplysc silenced shrimp, suggesting Fplysc is the important molecule in shrimp antimicrobial and antiviral response. In conclusion, the results provide some insights into the function of Fplysc in shrimp against bacterial and viral infection.

Abstract
Interleukin-1 receptor-associated kinase (IRAK) family members play important roles in myeloid differentiation primary response 88 (MyD88)-dependent toll-like receptor (TLR) signaling, the crucial innate immune pathway in vertebrates. In the present study, the IRAK family gene IRAK-M (also called IRAK3) from grass carp (Ctenopharyngodon idella) was cloned and characterised. IRAK-M was mainly enriched in the spleen, and the significantly altered expression was observed after grass carp reovirus (GCRV) infection. Subcellular localisation showed that IRAK-M protein distributed uniformly in the entire cell and co-localised with MyD88 in the cytoplasm of transfected cells. Additionally, the interaction between IRAK-M and MyD88 was confirmed by bimolecular fluorescence complementation (BiFC) system. Moreover, deficient of IRAK-M in C. idella kidney cell line (CIK) with small interference RNA (siRNA) upregulated polyinosinic:polycytidylic acid (poly(I:C))-induced inflammatory cytokines production, including interleukin 8 (IL-8), IL-6, and tumour necrosis factor α (TNF-α), which reveals that IRAK-M functions as a negative regulator of inflammatory cytokines. Taken together, our results demonstrate that IRAK-M gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the IRAK-M in teleosts.

Abstract
In this study, the cDNA fragments of cytokines (il-8) and toll-like receptor (TLR) pathway signaling molecules (myd88, irak-1, irf5, and irf7) in the Chinese rare minnow were cloned and exhibited a high amino-acid sequence identity compared to other cyprinid fish orthologs. The mRNA expressions of these genes in the different tissues (liver, brain, spleen, kidney, and skin) were observed. The highest expression levels of myd88, irak-1, and irf5 were detected in the spleen, whereas il-8 and irf7 were detected in the kidney and liver respectively. The mRNA expression of irak-1, irf5, and irf7 in the liver from 0.1 μg/L and 0.5 μg/L CPF treatments were significantly increased on day 7 (p < 0.05), whereas the levels of only irak-1 and irf7 were markedly increased on day 28 (p < 0.05). Moreover, the mRNA expression of il-8 in the spleen following 0.5 μg/L CPF treatments was significantly decreased on day 7 (p < 0.05), whereas significantly decrease were observed in the levels of irf7 in the spleen at 2.5 μg/L CPF on days 7 and 28 (p < 0.05). The 0.1 μg/L and 0.5 μg/L of CPF significantly induced the levels of irak-1 and myd88 in the spleen after 28 d exposure (p < 0.05). Therefore, the high induction of cytokines and TLR pathway signaling molecules demonstrated that Chinese rare minnow was immune-compromised exposed to CPF. Moreover, our finding indicated that these immune-related genes could be feasible to screen for substances hazardous to the immune system of fish.

Abstract
Diseases have caused tremendous economic losses and become the major problem threatening the sustainable development of shrimp aquaculture. The knowledge of host defense mechanisms against invading pathogens is essential for the implementation of efficient strategies to prevent disease outbreaks. Like other invertebrates, shrimp rely on the innate immune system to defend themselves against a range of microbes by recognizing and destroying them through cellular and humoral immune responses. Detection of microbial pathogens triggers the signal transduction pathways including the NF-κB signaling, Toll and Imd pathways, resulting in the activation of genes involved in host defense responses. In this review, we update the discovery of components of the Toll and Imd pathways in shrimp and their participation in the regulation of shrimp antimicrobial peptide (AMP) synthesis. We also focus on a recent progress on the two most powerful and the best-studied shrimp humoral responses: AMPs and melanization. Shrimp AMPs are mainly cationic peptides with sequence diversity which endues them the broad range of activities against microorganisms. Melanization, regulated by the prophenoloxidase activating cascade, also plays a crucial role in killing and sequestration of invading pathogens. The progress and emerging research on mechanisms and functional characterization of components of these two indispensable humoral responses in shrimp immunity are summarized and discussed. Interestingly, the pattern recognition protein (PRP) crosstalk is evidenced between the proPO activating cascade and the AMP synthesis pathways in shrimp, which enables the innate immune system to build up efficient immune responses.

Abstract
Tumor necrosis factor receptor-associated factor 6 (TRAF6) is an important cytoplasm signal adaptor that mediates signals activated by tumor necrosis factor receptor (TNFR) superfamily and the Interleukin-1 receptor/Toll-like receptor (IL-1/TLR) superfamily. In the study, the full-length cDNA of a TRAF6 homolog (FpTRAF6) was identified from Fenneropenaeus penicillatus. The full-length cDNA of FpTRAF6 is 2033 bp long, with an open reading frame (ORF) encoding a putative protein of 594 amino acids, including a RING type Zinc finger, two TRAF-type Zinc fingers, and a conserved C-terminal meprin and TRAF homology (MATH) domain. The overall amino acid sequence identity between FpTRAF6 and other TRAF6s ranged from 62.7 to 94.1% for crustaceans and from 45.6 to 59.3% for mollusca. Real-time qRT-PCR indicated that FpTRAF6 was constitutively expressed in various tissues of F. penicillatus. The temporal expression patterns of FpTRAF6 mRNA were different in the different tissues after microbial challenge. FpTRAF6 was downregulated in the heart, no obvious changes in the gill, intestine and hemocytes, and upregulated in other tested tissues after WSSV challenge. After V. alginolyticus injection, FpTRAF6 was downregulated in the heart and intestine, upregulated in the gill, lymphoid organ and hematopoietic organ, and no obvious changes in other tested tissues. RNAi assay was carried out to investigate the function of FpTRAF6. The results showed that silencing FpTRAF6 gene could inhibit peroxinectin expression in vivo, and enhance the sensitivity of shrimps to WSSV and V. alginolyticus challenge, suggesting FpTRAF6 could play a positive role against bacterial and viral pathogens. In conclusion, the results of the study provide some insights into the function of FpTRAF6 in activating TLRs signaling pathway and the host defense against invading pathogens.
