COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY. PART D, GENOMICS & PROTEOMICS 2023; 47:101117. [PMID: 37591053 DOI: 10.1016/j.cbd.2023.101117] [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: 04/20/2023] [Revised: 08/05/2023] [Accepted: 08/05/2023] [Indexed: 08/19/2023]
Abstract
The sea cucumber Holothuria leucospilota, a nutritive and commercial marine species, has a high protein and low lipid content. To date, the mechanisms underlying gender determination and differentiation in sea cucumbers remain unclear. Identifying gender-specific molecular markers is an effective method of revealing the genetic basis of gender determination and differentiation. The inability to distinguish between male and female individuals causes reproductive efficiency to decline in aquaculture. In this study, we used the gonads of the sea cucumber H. leucospilota as samples to conduct the experiment. The differentially abundant metabolites (DAMs) detected by liquid chromatography-mass spectrometry were enriched in pathways associated with prolactin metabolism, insulin metabolism, hypoxia-inducible factor-1 signaling, and calcium signaling. At the transcriptome level, Illumina sequencing was performed on H. leucospilota, demonstrating that gender-specific expression genes were enriched in the retinoic acid-inducible gene I-like receptor signaling pathway, C-type lectin receptor signaling pathway, alpha-linolenic acid metabolism, and ether lipid metabolism by the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. By analyzing the common pathways between DAMs and differentially expressed genes, we found that gender-related genes of H. leucospilota were mostly enriched in the necroptosis pathway and the cysteine and methionine metabolism pathways. According to the common pathways, uch-sc1 and uch-sc2 are male-specific expression genes, and uch-sc3 and bhmt are female-specific expression genes at the mRNA level. These results provide information on gender differences in H. leucospilota.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a 17 kDa calcium-binding protein associated with numerous inflammatory diseases. The full-length cDNA of AIF-1 has been identified in grass carp, Ctenopharyngodon idellus in our previous study, and it was assumed to be a novel molecule involved in immune responses. To clarify this aspect, the level of AIF-1 expression was amplified and reduced in grass carp peripheral blood leukocytes via transfection of vector pcDNA3.1-AIF1-EGFP and pLKO.1-shRNA-EGFP-puro, respectively. Thereafter, AIF-1 stimulated cell proliferation, inhibited cell apoptosis, which might benefit from improved mitochondrial function as evidenced by increased mitochondrial membrane potential, subsequently promoted ATP production. In addition, AIF-1 induced leukocyte migration via up-regulated monocyte chemotactic protein-1(MCP-1) secretion, enhanced neutral red uptake into leukocyte, provoked pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α), interleukin 1β (IL1β), interleukin 6 (IL6), interleukin 8 (IL8) and suppressed anti-inflammatory cytokine interleukin 10 (IL10) production. These results indicated AIF-1 played a critical role in grass carp innate immune system.

Abstract
The papilla number is one of the most economically important traits of sea cucumber in the China marketing trade. However, the genetic basis for papilla number diversity in holothurians is still scarce. In the present study, we conducted genome-wide association studies (GWAS) for the trait papilla number of sea cucumbers utilizing a set of 400,186 high-quality SNPs derived from 200 sea cucumbers. Two significant trait-associated SNPs that passed Bonferroni correction (P < 1.25E-7) were located in the intergenic region near PATS1 and the genic region of EIF4G, which were reported to play a pivotal role in cell growth and proliferation. The fine-mapping regions around the top two lead SNPs provided precise causative loci/genes related to papilla formation and cellular activity, including PPP2R3C, GBP1, and BCAS3. Potential SNPs with P < 1E-4 were acquired for the following GO and KEGG enrichment analysis. Moreover, the two lead SNPs were verified in another population of sea cucumber, and the expressive detection of three potential candidate genes PATS1, PPP2R3C, and EIF4G that near or cover the two lead SNPs was conducted in papilla tissue of TG (Top papilla number group) and BG (Bottom papilla number group) by qRT-PCR. We found the significantly higher expression profile of PATS1 (3.34-fold), PPP2R3C (4.90-fold), and EIF4G (4.23-fold) in TG, implying their potential function in papilla polymorphism. The present results provide valuable information to decipher the phenotype differences of the papilla trait and will provide a scientific basis for selective breeding in sea cucumbers.

Allograft Inflammatory Factor-1 in Metazoans: Focus on Invertebrates. BIOLOGY 2020; 9:biology9110355.

Abstract
Simple Summary During their life, all living organisms defend themselves from pathogens using complex strategies. Vertebrates and invertebrates share mechanisms and molecules that guarantee their overall bodily integrity. Allograft inflammatory factor-1 (AIF-1) is a protein extensively studied in vertebrates, and especially in mammals. This factor, generally involved in inflammation events occurring upon pathogenic infection or tissue injury, is linked to several important human diseases. This review collects data on the presence and role of AIF-1 in invertebrates, which are still poorly investigated organisms. Multiple alignment and phylogenetic analysis reveal that AIF-1 is conserved in vertebrates and invertebrates, suggesting similarity of functions. In some invertebrate species, the expression of AIF-1 increases considerably after a bacterial challenge, indicating that it plays a key role during the immune responses. This review highlights the importance of studying this protein in invertebrates as a way to improve our knowledge of innate immunity mechanisms and to better understand inflammatory regulation events in mammals. Abstract Allograft inflammatory factor-1 (AIF-1) is a calcium-binding scaffold/adaptor protein often associated with inflammatory diseases. Originally cloned from active macrophages in humans and rats, this gene has also been identified in other vertebrates and in several invertebrate species. Among metazoans, AIF-1 protein sequences remain relatively highly conserved. Generally, the highest expression levels of AIF-1 are observed in immunocytes, suggesting that it plays a key role in immunity. In mammals, the expression of AIF-1 has been reported in different cell types such as activated macrophages, microglial cells, and dendritic cells. Its main immunomodulatory role during the inflammatory response has been highlighted. Among invertebrates, AIF-1 is involved in innate immunity, being in many cases upregulated in response to biotic and physical challenges. AIF-1 transcripts result ubiquitously expressed in all examined tissues from invertebrates, suggesting its participation in a variety of biological processes, but its role remains largely unknown. This review aims to present current knowledge on the role and modulation of AIF-1 and to highlight its function along the evolutionary scale.

Abstract
The South African abalone Haliotis midae is a commercially important species farmed at high densities in land-based aquaculture systems. Disease outbreaks have had a severe financial impact on the abalone industry yet the molecular mechanisms underlying the immune response of H. midae remain obscure. In this study, a comparative shotgun proteomics approach using iTRAQ coupled with LC-MS/MS was employed to investigate H. midae proteome changes in response to Vibrio anguillarum challenge. A total of 118 non-redundant, unique haemocyte proteins were identified and quantified, with 16 proteins significantly regulated. Hierarchical clustering and pathway analysis uncovered a coordinated response dominated by calcium and cAMP signalling via activation of MAPK cascades. Early up-regulated biological processes involve phagocytosis, nitric oxide production and ATP-synthesis, whilst down-regulated responses were predominantly involved in the regulation of apoptosis. The late up-regulated response involved protein kinase activity and detoxification processes. Expression of selected proteins was validated by Western blot. A putative allograft inflammatory factor-1 protein was further selected to establish its functional molecular role in haemocytes. Confocal imaging revealed that allograft inflammatory factor-1 regulates phagocytosis via a functional interaction with filamentous actin. This is the first time a high-throughput proteomics approach has been used to investigate the immune response of H. midae.

Abstract
Allograft inflammatory factor-1 (AIF-1) is an inflammation-related protein mainly produced by immune cells, such as monocyte/macrophages and activated T lymphocytes. It is essential for the survival and proinflammatory activity of immune cells. However, the function of AIF-1 in chicken still has not been defined. In the present study, AIF-1-like (AIF1L) gene was identified in Luning chicken. Bioinformatics analysis revealed that the molecular weight of the chicken AIF-1 protein was 16290.8 Da. AIF1L contained a Ca2+ binding EF hand and could interact with actin filament. Its transcript was found in all tested tissues including spleen, brain, heart, kidney, liver, thymus, bursa of Fabricius, lung, and a relative low-level expression was detected in leg muscle. Furthermore, AIF1L expression in peripheral blood lymphocyte was depressed in a dose-dependent manner with cadmium exposure and peripheral blood lymphocyte viability decrease displayed a similar pattern with AIF1L expression. The results indicated that newly identified chicken AIF1L might be associated with lymphocyte viability.

Abstract
Ionized calcium-binding adapter molecule 1 (Iba1), also known as allograft inflammatory factor 1 (AIF-1), is a highly conserved cytoplasmic scaffold protein. Studies strongly suggest that Iba1 is associated with immune-like reactions in all Metazoa. In the mammalian brain, it is abundantly expressed in microglial cells and is used as a reliable marker for this cell type. The present study used multiple-label microscopy and Western blotting to examine Iba1 expression in the telencephalon of 2 galeomorph shark species, the swellshark (Cephaloscyllium ventriosum) and the horn shark (Heterodontus francisci), a member of an ancient extant order. In the swellshark, high Iba1 expression was found in radial ependymoglial cells, many of which also expressed glial fibrillary acidic protein. Iba1 expression was absent from most cells in the horn shark (with the possible exception of perivascular cells). The difference in Iba1 expression between the species was supported by protein analysis. These results suggest that radial ependymoglia of the elasmobranchs may be functionally related to mammalian microglia and that Iba1 expression has undergone evolutionary changes in this cartilaginous group.

Abstract
Allograft inflammatory factor 1 (AIF-1) is a highly conserved gene involved in inflammation, cloned and characterized in several evolutionary distant animal species. Here, we report the molecular identification, characterization and expression of AIF-1 from the common sea urchin Paracentrotus lividus. In this species, AIF-1 encodes a predicted 151 amino acid protein with high similarity to vertebrate AIF-1 proteins. Immunocytochemical analyses on coelomocytes reveal localization of the AIF-1 protein in amoebocytes (perinuclear cytoplasmic zone) and red sphaerulocytes (inside granules), but not in vibratile cells and colorless sphaerula cells. The significant increase of AIF-1 expression (mRNA and protein) found in the coelomocytes of the sea urchin after Gram + bacterial challenge suggests the involvement of AIF-1 in the inflammatory response. Our analysis on P. lividus AIF-1 contributes to elucidate AIF-1 function along the evolutionary scale and consolidate the key evolutionary position of echinoderms throughout metazoans with respect to the common immune paths.

Abstract
Gene family encoding allograft inflammatory factor-1 (AIF-1) is well conserved among organisms; however, there is limited knowledge in lower organisms. In this study, the first AIF-1 homologue from cnidarians was identified and characterised in the sea anemone Anemonia viridis. The full-length cDNA of AvAIF-1 was of 913 bp with a 5' -untranslated region (UTR) of 148 bp, a 3'-UTR of 315 and an open reading frame (ORF) of 450 bp encoding a polypeptide with149 amino acid residues and predicted molecular weight of about 17 kDa. The predicted protein possesses evolutionary conserved EF hand Ca2+ binding motifs, post-transcriptional modification sites and a 3D structure which can be superimposed with human members of AIF-1 family. The AvAIF-1 transcript was constitutively expressed in all tested tissues of unchallenged sea anemone, suggesting that AvAIF-1 could serve as a general protective factor under normal physiological conditions. Moreover, we profiled the transcriptional activation of AvAIF-1 after challenges with different abiotic/biotic stresses showing induction by warming conditions, heavy metals exposure and immune stimulation. Thus, mechanisms associated to inflammation and immune challenges up-regulated AvAIF-1 mRNA levels. Our results suggest its involvement in the inflammatory processes and immune response of A. viridis.

Abstract
As the most important disulfide bond reducates of intracellular oxidordeuctase, thioredoxin (TRX) plays a crucial role in maintaining reducing state of intracellular proteins to normally perform their function. In this study, a cDNA of TRX-like protein gene from Apostichopus japonicus (denoted as AjTRX) was cloned and characterized. The full-length cDNA of AjTRXwas of 1870 bp, consisting of a 5'-UTR of 101 bp, a long 3'-UTR of 887 bp and a 882 bp open reading frame (ORF) encoding a 293 amino acids. The predicted molecular mass and the theoretical PI of the deduced amino acids of AjTRX were 32.3 kDa and 5.52, respectively. Phylogenetic trees showed that AjTRX had a closer evolution relationship with TRX from Strongylocentrotus purpuratus. AjTRX was found to be ubiquitously expressed in all examined tissues including longitudinal muscle, coelomocytes, tube feet, intestine, respiratory tree and body wall indicating a general role in physiological processes. Temporal expression pattern of AjTRX in coelomocytes showed that AjTRX reached two peak expression levels at 8 h and 48 h after Vibrio splendidus challenge with a 8.6 and 9.3-fold increase compared to their control groups, respectively. The recombinant AjTRX protein (rAjTRX) displayed obvious antioxidant activity in a dose-dependent manner, and the higher reducing activity was detected in 20 μM experimental group. All these results strongly suggested that AjTRX could play an important role as an antioxidant in a physiological context, and might be involved in the process of bacterial challenge.

Abstract
TNF receptor associated factors (TRAFs) are a family of proteins primarily involved in both adaptive and innate immunity. In this study, we identified a novel TRAF3 gene in Apostichopus japonicus by transcriptome sequencing and RACE approaches (designated as AjTRAF3). The full-length of AjTRAF3 was of 2796 bp including a 5' untranslated region (UTR) of 83 bp, a 3' UTR of 1066 bp and a putative open reading frame of 1647 bp encoding a polypeptide of 548 amino acid residues. The representative domains such as a RING finger domain (residues 54-96), two TRAF domains with zinc finger structure (residues 141-228), a coiled coil and a meprin and TRAF homology (MATH) domain (residues 396-522) were all detected in the deduced amino acids of AjTRAF3. AjTRAF3 was ubiquitously expressed in all examined tissues with predominant expression in the body wall and slightly weaker in intestine, respiratory tree, tube feet, coelomocytes and longitudinal muscle. Time-course expression analysis in coelomocytes revealed that AjTRAF3 was significantly depressed towards Vibrio splendidus infection with a 0.20-fold decrease at 12 h, compared to control levels. AjTRAF3 silencing could elevate intracellular ROS levels by 2.08-fold and 2.09-fold compared to each control group in vitro and in vivo, respectively. Taken together, all these results suggested that AjTRAF3 may play a crucial role in the processes of anti-bacteria response in sea cucumber through regulating ROS production.

Abstract
Allograft Inflammatory Factor-1 (AIF-1) is an inflammation responsive protein that is mainly produced by immunocytes. As a pro-inflammatory cytokine, AIF-1 is a key moderator in host immune defense reaction. However, the inflammatory properties of AIF-1 in freshwater fish still hasn't been clearly elucidated. In the present study, AIF-1 was identified from grass carp (Ctenopharynogodon idella). It's transcript was found in all examined tissues including brain, spleen, kidney, liver, heart, while a relative low level in red muscle, gill, thymus, white muscle, intestine and fin. Furthermore, AIF-1 transcription and expression level decreased in spleen and didn't change a lot in kidney with cadmium induction, respectively. The result indicated that grass carp AIF-1 might be involved in cadmium-induced stress.

Abstract
MicroRNAs (miRNAs), as a family of non-coding small RNAs, play important roles in the post-transcriptional regulation of gene expression. Sea cucumber (Apostichopus japonicus) is an important economic species which is widely cultured in East Asia. The longitudinal muscle (LTM) and respiratory tree (RPT) are two important tissues in sea cucumber, playing important roles such as respiration and movement. In this study, we identified and characterized miRNAs in the LTM and RPT of sea cucumber (Apostichopus japonicus) using Illumina HiSeq 2000 platform. A total of 314 and 221 conserved miRNAs were identified in LTM and RPT, respectively. In addition, 27 and 34 novel miRNAs were identified in the LTM and RPT, respectively. A set of 58 miRNAs were identified to be differentially expressed between LTM and RPT. Among them, 9 miRNAs (miR-31a-3p, miR-738, miR-1692, let-7a, miR-72a, miR-100b-5p, miR-31b-5p, miR-429-3p, and miR-2008) in RPT and 7 miRNAs (miR-127, miR-340, miR-381, miR-3543, miR-434-5p, miR-136-3p, and miR-300-3p) in LTM were differentially expressed with foldchange value being greater than 10. A total of 14,207 and 12,174 target genes of these miRNAs were predicted, respectively. Functional analysis of these target genes of miRNAs were performed by GO analysis and pathway analysis. This result provided in this work will be useful for understanding biological characteristics of the LTM and RPT of sea cucumber and assisting molecular breeding of sea cucumber for aquaculture.

Abstract
In order to explore the potential roles of microRNAs (miRNAs) in regulating Toll-like receptor (TLR) pathways, we identified Toll interacting protein as a putative target of miR-200 in Apostichopus japonicus coelomocytes by RNA-seq screening (denoted as AjTollip). The positive expression profiles of miR-200 and AjTollip were detected in both LPS exposure primary coelomocytes and Vibrio splendidus challenge sea cucumber. Co-infection miR-200 mimics significantly elevated the expression of AjTollip and its down-stream molecules. In contrast, miR-200 inhibitor significantly repressed the expression of these TLR-pathway members. More importantly, miR-200 displayed not only to enhance coelomocytes antibacterial activities, but to suppress LPS priming in vitro. Overall, all these results will enhance our understanding on miR-200 regulatory roles in anti-bacterial process in sea cucumber.

Abstract
The transcription factor activator protein-1 (AP-1) is an important gene expression regulator with typical Jun and region-leucine zipper (bZIP) domains and can respond to a plethora of physiological and pathological stimulus. In this study, we identified a novel AP-1 gene in Apostichopus japonicus by transcriptome sequencing and RACE approaches (designated as AjAP-1). The full-length of AjAP-1 was of 2944 bp including a 5' untranslated region (UTR) of 201 bp, a 3' UTR of 1753 bp and a putative open reading frame of 990 bp encoding a polypeptide of 329 amino acid residues. Two representative domains of Jun and bZIP as well as two nuclear localization signals (NLSs) were also detected in deduced amino acid of AjAP-1. Spatial distribution expression indicated that AjAP-1 was ubiquitously expressed in all examined tissues with predominant expression in the body wall, moderate in the tube feet, respiratory tree and colemocytes and slightly weak in the intestine and longitudinal muscle. Time-course expression analysis in intestine and coelomocytes revealed that AjAP-1 both reached its peak expression at 4 h after Vibrio splendidus challenge with a 2.6 and 8.2-fold increase compared to their control groups, respectively. Taken together, all these results suggested that AjAP-1 was a novel immune factor and might be involved in the processes of anti-bacteria response in sea cucumber.
