[PMID: 38240954 PMCID: PMC10869415 DOI: 10.1007/s10126-024-10285-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 01/04/2024] [Indexed: 02/16/2024]
Abstract
There is clear evidence that the oceans are warming due to anthropogenic climate change, and the northeastern coast of USA contains some of the fastest warming areas. This warming is projected to continue with serious biological and social ramifications for fisheries and aquaculture. One species particularly vulnerable to warming is the Atlantic surfclam (Spisula solidissima). The surfclam is a critically important species, linking marine food webs and supporting a productive, lucrative, and sustainable fishery. The surfclam is also emerging as an attractive candidate for aquaculture diversification, but the warming of shallow coastal farms threatens the expansion of surfclam aquaculture. Little is known about the adaptive potential of surfclams to cope with ocean warming. In this study, the surfclam transcriptome under heat stress was examined. Two groups of surfclams were subjected to heat stress to assess how artificial selection may alter gene expression. One group of clams had been selected for greater heat tolerance (HS) and the other was composed of random control clams (RC). After a 6-h exposure to 16 or 29 °C, gill transcriptome expression profiles of the four temperature/group combinations were determined by RNA sequencing and compared. When surfclams experienced heat stress, they exhibited upregulation of heat shock proteins (HSPs), inhibitors of apoptosis (IAPs), and other stress-response related genes. RC clams differentially expressed 1.7 times more genes than HS clams, yet HS clams had a stronger response of key stress response genes, including HSPs, IAPs, and genes involved with mitigating oxidative stress. The findings imply that the HS clams have a more effective response to heat stress after undergoing the initial selection event due to genetic differences created by the selection, epigenetic memory of the first heat shock, or both. This work provides insights into how surfclams adapt to heat stress and should inform future breeding programs that attempt to breed surfclam for greater heat tolerance, and ultimately bring greater resiliency to shellfish farms.

Abstract
The microbiome in the female reproductive tract plays an essential role in immune modulation and reproductive health. However, various microbes become established during pregnancy, the balance of which plays a crucial role in embryonic development and healthy births. The contribution of disturbances in the microbiome profile to embryo health is poorly understood. A better understanding of the relationship between reproductive outcomes and the vaginal microbiota is needed to optimize the chances of healthy births. In this regards, microbiome dysbiosis refers to conditions in which the pathways of communication and balance within the normal microbiome are imbalanced due to the intrusion of pathogenic microorganisms into the reproductive system. This review summarizes the current state of knowledge on the natural human microbiome, with a focus on the natural uterine microbiome, mother-to-child transmission, dysbiosis, and the pattern of microbial change in pregnancy and parturition, and reviews the effects of artificial uterus probiotics during pregnancy. These effects can be studied in the sterile environment of an artificial uterus, and microbes with potential probiotic activity can be studied as a possible therapeutic approach. The artificial uterus is a technological device or biobag used as an incubator, allowing extracorporeal pregnancy. Establishing beneficial microbial communities within the artificial womb using probiotic species could modulate the immune system of both the fetus and the mother. The artificial womb could be used to select the best strains of probiotic species to fight infection with specific pathogens. Questions about the interactions and stability of the most appropriate probiotics, as well as dosage and duration of treatment, need to be answered before probiotics can be a clinical treatment in human pregnancy.

Abstract
Toll-like receptors (TLRs) mediated signaling plays a vital role in activating innate and adaptive immunity. Although TLR mediated signaling has been comprehensively investigated in mammalian species, the mechanisms underlying TLR signaling in molluscs remain obscure. In the present study, a novel TLR isoform namely McTLR-like1 was identified in the thick shell mussel Mytilus coruscus. McTLR-like1 was highly expressed in molluscan immune-related tissues, and its transcriptional levels in hemocytes were significantly increased when challenged by V. alginolyticus. McTLR-like1 activated nuclear factor κB (NF-κB) and strengthened the transcription and phosphorylation of NF-κB subunit P65 in mammalian cells. Upon the silencing of McTLR-like1, the mRNA expression levels of pro-inflammatory cytokines were down-regulated, and the animals exhibited higher levels of resistance when challenged with V. alginolyticus. McMyD88a mRNA expression was also downregulated alongside McTLR-like1. Furthermore, GST-pull down assays revealed a visible affinity between McTLR-like1 and McMyD88a. Collectively, these results demonstrated that the newly identified gene affiliated to the molluscan TLR family and plays a role in the TLR-mediated activation of inflammatory response via its affinity with MyD88. The present study enhances our knowledge of TLR signaling mechanisms in molluscs and provides new insights into the evolution of TLRs.

Abstract
Background Drought has become the major abiotic stress that causes losses in rice yields and consequently is one of the main environmental factors threatening food security. Long non-coding RNA (lncRNA) is known to play an important role in plant response to drought stress, while the mechanisms of competing endogenous RNA (ceRNA) in drought resistance in upland rice have been rarely reported. Results In our study, a total of 191 lncRNAs, 2115 mRNAs and 32 miRNAs (microRNAs) were found by strand-specific sequencing and small RNA sequencing to be differentially expressed in drought-stressed rice. Functional analysis of results indicate that they play important roles in hormone signal transduction, chlorophyll synthesis, protein synthesis and other pathways. Construction of a ceRNA network revealed that MSTRG.28732.3 may interact with miR171 in the chlorophyll biosynthesis pathway and affect the ability of plants to withstand drought stress by regulating Os02g0662700, Os02g0663100 and Os06g0105350. The accuracy of the regulatory network was verified by qRT-PCR. Conclusion Our results provide a theoretical basis for future studies on the potential function of lncRNA in plant drought resistance, and they provide new genetic resources for drought-resistant rice breeding.

Abstract
Bacterial disease outbreaks in filter feeder bivalve Hyriopsis cumingii as water contamination become more frequent in the water ecosystem, especially in intensive aquaculture habitats. To characterize host-pathogen interactions between H. cumingii and bacterial infection, we investigated the effects of Stenotrophomonas maltophilia HOP3 and Aeromonas veronii GL1 on the antioxidant response, tissue invasion and transcriptome expression of H. cumingii by infectivity trials. We showed that bacterial infections resulted in tubular necrosis of the hepatopancreas and induced the acute immune response in H. cumingii. The transcriptomic study identified a total of 5957 differentially expressed genes (DEGs) after A. veronii challenge. These DEGs were implicated in 302 KEGG pathways, notably in Apoptosis, Phagosome and Lysosome. The results showed that the relative expressions of all six immune-related DEGs were effectively stimulated with A. veronii, accompanied by tissue differences. Overall, these findings will contribute to an analysis of the immune response of H. cumingii to bacterial infection at the transcriptomic level and its genomic resource for research.

Abstract
Toll-like receptor (TLR) family plays an important role in innate immunity for detection of and defense against microbial pathogens. In this study, a novel toll-like receptor (HcTLRn) was characterized from freshwater pearl mussel H. cumingii. The complete sequence of HcTLRn was 3725 bp, and the open reading frame (ORF) encoded 718 amino acid residues. Predicted HcTLRn protein possessed seven atypical leucine-rich repeat (LRR) domains, two typical LRR subfamily domains, a C-terminal domain LRR, a transmembrane domain and an intracellular Toll/interleukin-1 (IL-1) receptor domain. Transcripts of HcTLRn were constitutive expressed in the tissues of healthy mussels and were markedly induced in hepatopancreas and gills after lipopolysaccharide (LPS), peptidoglycan (PGN) and polyinosinic polycytidylic acid (ploy I: C) stimulation. Knockdown of HcTLRn in vivo significantly decreased the mRNA levels of TLR pathway transcription factors p65 and p105 as well as antimicrobial peptides (AMPs) including lysozyme (HcLys), theromacin (HcTher), whey acidic protein (HcWAP), LPS-binding protein/bactericidal permeability increasing protein (HcLBP/BPI) 1 and 2 after mussels challenged by LPS. In situ hybridization results showed that HcTLRn mRNA was significantly increased in hemocytes after LPS, PGN and poly I:C stimulation. HcTLRn protein was mainly expressed in hepatopancreas and gills and was significantly increased after LPS stimulation. Moreover, recombinant extracellular domain of HcTLRn (HcTLRn-ECD) proteins could bind to a variety of bacterial and pathogen-associated molecular patterns such as LPS, PGN, and poly I:C in vitro. Subcellular localization results showed that HcTLRn was mainly distributed near the cell membrane and in cytoplasm. Over-expression of HcTLRn activated the NF-κB luciferase reporter in HEK293T cells. Collectively, these results suggested that HcTLRn was a TLR family member that might play an important role in activation of NF-κB signal pathway in Mollusca.

Comp Biochem Physiol B Biochem Mol Biol 2020; 251:110521.

Abstract
The complement C1r/C1s, Uegf, and Bmp1 (CUB) domains, which are most exclusively found in extracellular and plasma membrane-related proteins, are involved in various biological processes. In this study, a CUB domain-containing protein (designed as HcCDCP) was cloned and characterized from freshwater pearl mussel (Hyriopsis cumingii). The 2280 bp complete cDNA of the HcCDCP contained a 1002 bp open reading frame, which encoded a protein with 333 amino acids. The predicted HcCDCP protein contained a typical CUB domain and a transmembrane region. The tissue distribution analysis indicated that the HcCDCP was detected in all tissues, and the highest expression was found in hepatopancreas followed by gills. After infection with bacteria (i.e., Staphylococcus aureus and Vibrio parahaemolyticus), virus (white spot syndrome virus) and virus analogs (poly[I:C]), the mRNA level of the HcCDCP was significantly upregulated, suggesting that the HcCDCP might be involved in host immune defense response. The RNA interference revealed that the silencing of the HcCDCP could evidently inhibit the expression levels of lysozyme and tumor necrosis factor. Moreover, the recombinant protein of the CUB domain (rCUB) possessed binding capacity to eight different kinds of bacteria. The polysaccharide binding assay showed that the rCUB specifically bound to lipopolysaccharide, peptidoglycan, and D-mannose. This study provided valuable information for exploring the biological roles of CDCPs in the host defense system of mollusks.
