Abstract
High mobility group box 1 (HMGB1) is a multifunctional regulator that plays different roles in various physiological and pathological processes including cell development, autophagy, inflammation, tumor metastasis, and cell death based on its cellular localization. Unlike mammalian HMGB1, two HMGB1 paralogues (HMGB1a and HMGB1b) have been found in fathead minnow and other fish species and its function as an inflammatory cytokine has been well investigated. However, the role of fish HMGB1 in autophagy regulation has not been well clarified. In the present study, we generated HMGB1 paralogues single (HMGB1a-/- and HMGB1b-/-) and double knockout (DKO) epithelioma papulosum cyprini (EPC) cells from fathead minnow by CRISPR/Cas9 system, and the knockout efficiency of these genes was verified at both gene and protein levels. In this context, the effects of HMGB1 gene knockout on the protein expression of microtubule-associated protein 1 light chain 3 II (LC3-II), an autophagy marker, were determined, showing that single knockout of two HMGB1 paralogues significantly decreased the expression of LC3-II, and these inhibitory effects were further amplified in HMGB1 DKO cells under both basal and rapamycin treatment conditions, indicating the role of two HMGB1 paralogues in fish autophagy. In agreement with this notion, overexpression of HMGB1a or HMGB1b with Flag-tag markedly upregulated LC3-II protein expression. Interestingly, overexpressing two paralogues distributed in both cytoplasm and nucleus. Finally, the role of HMGB1-mediated autophagy was further explored, finding that HMGB1 could interact with Beclin1, a key initiation factor of autophagy. Taken together, these findings highlighted the role of HMGB1 paralogues as the autophagy regulator and increased our understanding of autophagic machinery in teleost.

Abstract
OBJECTIVE High-mobility group box 1 (HMGB1) is a highly conserved nuclear protein and participates in the immune response to pathogens in bony fish. In this study, the structure and function of HMGB1 in the cyprinid fish Schizothorax prenanti (SpHMGB1) were investigated. METHODS The spatial structure of SpHMGB1 was predicted by CPHmodels. Quantitative reverse transcription PCR was used to detect the mRNA of SpHMGB1 in different tissues and Streptococcus agalactiae infection. The macrophage was treated with synthetic SpHMGB1-B box peptide to analyze the inflammatory activity. RESULT Structurally, SpHMGB1 had the conserved A box, B box, and acid tail compared with Zebrafish Danio rerio and mice Mus musculus. SpHMGB1 was universally expressed in various tissues, with the highest expression in the middle kidney. In vivo, SpHMGB1 was significantly induced in response to Streptococcus agalactiae infection in the blood and spleen. Synthetic SpHMGB1-B box peptide activated respiratory burst and up-regulated the messenger RNA expression of interleukin-1β, tumor necrosis factor α, interleukin-10, interferon regulatory factor 1, interferon regulatory factor 7, C-X-C motif chemokine ligand 11-1, C-X-C motif chemokine ligand 11-2, and toll-like receptor 4 in macrophages. CONCLUSION This study suggested that SpHMGB1 participated in the response to bacterial pathogens and that SpHMGB1-B box peptide played an important role in mediating the immune response of S. prenanti.

Abstract
High mobility group box 1 (HMGB1) and high mobility group box 2 (HMGB2) were highly conserved nonhistone chromosomal proteins involved in DNA damage repair, innate immune and inflammatory response. In this study, Acipenser baerii HMGB1 (AbHMGB1) and HMGB 2 (HMGB2) were identified. The open reading frame (ORF) of AbHMGB1 was 621 bp which encoded 206 amino acids, and the ORF of AbHMGB2 was 630 bp encoded 209 amino acids. AbHMGB1 and AbHMGB2 were conserved compared with bony fish by phylogenetic analyzing. qRT-PCR showed that AbHMGB1 and AbHMGB2 were expressed in all examined tissues, AbHMGB1 was expressed abundantly in muscle, followed by head kidney and brain, and AbHMGB2 was highest expressed in gill, followed by brain and muscle. After Streptococcus iniae infection and PAMPs treatment, AbHMGB1 and AbHMGB2 were induced significantly. This study indicated that AbHMGB1 and AbHMGB2 are involved in the process of pathogenic infection and provided a basis for exploring the mechanism of Acipenser baerii enteritis induced by Streptococcus iniae.

HMGB1 Promotes Lymphangiogenesis through the Activation of RAGE on M2 Macrophages in Laryngeal Squamous Cell Carcinoma. DISEASE MARKERS 2022; 2022:4487435. [PMID: 35280439 PMCID: PMC8916867 DOI: 10.1155/2022/4487435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 01/20/2022] [Accepted: 02/04/2022] [Indexed: 11/17/2022]
Abstract
Background. Receptor for advanced glycation end products (RAGE) is implicated in tumor biology. Released high mobility group box protein 1 (HMGB1) ligand binding to RAGE receptor in tumor cells promotes tumor progression. The mechanisms of HMGB1-RAGE signaling in M2 macrophages involved in lymphangiogenesis in laryngeal carcinoma remain poorly understood. Here, we assessed the effect of HMGB1-RAGE signaling on M2 macrophages in lymphangiogenesis. Methods. HMGB1, CD163, and D2-40 in laryngeal squamous cell carcinoma (LSCC,
), laryngeal precursor lesions (LPLs,
), and vocal polyp (VP,
) were analyzed by immunohistochemistry. THP-1 cell-expressed RAGE gene was knocked down and then polarized to M0 macrophages and M2 macrophages. IL-23, TNF-α, TGF-β, and IL-10 were measured by ELISA; IL-1β, IL-12, IL-10, and CCL-13 were evaluated by RT-qPCR, and CD206, CD163, and RAGE were evaluated by western blot to evaluate whether classical M2 macrophages were obtained. Conditioned media from RAGE+/- M0 macrophages and RAGE+/- M2 macrophages incubated in the presence or absence of HMGB1, anti-Toll-like receptor (TLR)2, anti-TLR4 antibodies, and anti-VEGF-C antibodies were collected separately for human dermal lymphatic endothelial cells (HDLEC) for proliferation, migration, lymphangiogenesis assay, and VEGF-C concentration analysis. Results. HMGB1 and M2 macrophage densities were increased in LSCC (
). HMGB1 and M2 macrophage densities were significantly correlated with lymphatic vessel density (LVD) in LSCC (
). The HMGB1 overexpression and higher M2 macrophage density were involved in lymph node metastasis (
) and poor prognosis (
). In vitro, conditioned medium from HMGB1-stimulated RAGE+ M2 macrophages activated lymphangiogenesis by upregulating the VEGF compared to controls (
). On the contrary, RAGE knockdown obviously decreased the corresponding effects of HMGB1-preconditioned M2 macrophages upon HDLEC (
). HMGB1-TLR pathway does not significantly increase HDLEC proliferation, migration, and lymphangiogenesis on M2 macrophages. Conclusions. HMGB1 promotes lymphangiogenesis by activation of RAGE on M2 macrophages. Targeting RAGE may provide an effective therapeutic strategy against M2 macrophages in LSCC patients with lymph node metastasis.

Int J Biochem Cell Biol 2021; 142:106131.

Abstract
The supraneural body, also known as dorsal fat body is considered from adipose progenitors, and possesses hematopoietic activity. However, in-depth knowledge of cell-type by single-cell transcriptome sequencing and physiological functions are still lacking. Here, we determined at least four types of cells, such as white adipocytes, granulocytes, lymphocytes, and red blood cells by using 10 ×Genomics single-cell RNA sequencing (scRNA-Seq), hematoxylin-eosin (HE) staining, electron microscopy, immunofluorescence, and histochemistry. Additionally, most immune cells contain scattered small fat droplets except for white adipocytes with one large lipid droplet. The content of triglyceride in supraneural body is the highest compared with other tissues. The mRNA expression of both lipolysis-related genes and brown adipocytes-specific marker genes were up-regulated in supraneural body cells in response to epinephrine. Taken together, these data indicate that the supraneural body may play an important role in immune and fat storage. Our findings not only provided detailed insights into the unique molecular make-up of the supraneural body tissue, but also shed new light on future analyses of physiological functions in immune or lipid regulating.

MicroRNA expression profile in Lampetra morii upon Vibrio anguillarum infection and miR-4561 characterization targeting lip. Commun Biol 2021; 4:995.

Abstract
As a critical evolutionary pivot between invertebrates and vertebrates, lampreys provide rich genetic information. Lamprey immune protein (LIP) is a key immune regulator. MicroRNAs, well-conserved in the response to immunological stress, remain understudied in lamprey immunity. We generated a lamprey microRNA expression atlas, using deep sequencing, upon Vibrio anguillarum infection. Using comparative methods, we found that miR-4561 potentially regulates innate immunity via interaction with lip. We found a sequence in the 3′-UTR region of LIP mRNA complementary to the miR-4561 seed region; miR-4561 expression was negatively correlated with LIP. During V. anguillarum infection, miR-4561 inhibited LIP expression and bacterial clearance. Notably, LIP expression in supraneural body cells was necessary for the Gram-negative immune response. Additionally, we observed that overexpression of miR-4561 induced apoptosis in embryonic cells, suggesting a role in embryonic development. Collectively, we show lamprey microRNAs may significantly affect gene regulation and provide new insights on LIP-mediated immune regulation. Ma et al characterise differentially expressed miRNAs in Lamprey upon bacterial infection. They identify miR-4561 as being decreased after infection and show that it targets the 3′UTR of the mRNA encoding lamprey immune protein (LIP) involved in lamprey innate immunity and regulates survival in lamprey embryos.

Genomic analysis and functional characterization of immune genes from the RIG-I- and MAVS-mediated antiviral signaling pathway in lamprey. Genomics 2021; 113:2400-2412.

Abstract
Retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are well-known viral RNA sensors in the cytoplasm. RIG-I-mediated antiviral signals are activated by interacting with the adapter protein mitochondrial antiviral signaling (MAVS), which triggers interferon (IFN) responses via a signaling cascade. Although the complete RIG-I receptor signaling pathway has been traced back to teleosts, definitive evidence of its presence in lampreys is lacking. Here, we identified 13 pivotal molecules in the RIG-I signaling pathway in lamprey, and demonstrated that the original RIG-I/MAVS signaling pathway was activated and mediated the expression of unique immunity factors such as RRP4, to inhibit viral proliferation after viral infection in vivo and in vitro. This study confirmed the conservation of the RIG-I pathway, and the uniqueness of the RRP4 effector molecule in lamprey, and further clarified the evolutionary process of the RIG-I antiviral signaling pathway, providing evidence on the origins of innate antiviral immunity in vertebrates.

Abstract
Serine protease inhibitors (serpins) are a large protein family that is involved in various physiological processes and is known to regulate innate immunity pathways. However, research for the functional study of serpins in lamprey is limited. In the present study, a serpin gene was cloned and characterized from Lampetra japonica at molecular, protein and cellular levels, named L-serpin which belongs to family F serine protease inhibitors (serpin family). The L-serpin includes a serpin domain in the N-terminus. The mRNA transcript of L-serpin was extensively expressed in kidney, supraneural body, intestine, liver, heart, gill and the highest expression in leukocytes. The mRNA expression level of L-serpin increased significantly after Vibrio anguillarum, Staphylocccus aureus and Poly I:C stimulation and dramatically peak at 8 h. It is demonstrated that the L-serpin protected cells from lethal Gram-negative endotoxemia through associating with inhibition of lipopolysaccharide (LPS)-triggered cell death and inflammatory factors expression. Surface plasmon resonance (SPR) and the microbe binding assay were used to determine that L-serpin interacts directly with LPS (KD = 6.14 × 10-7 M). Furthermore, we confirmed L-serpin is a major inhibitor of complement activation by inactivating lamprey-C1q protein (KD = 2.06 × 10-6 M). Taken together, these findings suggest that L-serpin is a endogenous anti-inflammatory factor to defend against Gram-negative bacterial challenge and involved in lamprey innate immunity.

Abstract
Adiponectin (APN) is an important cytokine secreted by fat cells that is responsible for regulating numerous biological functions. However, the APN gene in lamprey and its precise function remain unidentified. In this study, the full-length cDNA sequence of L-APN was cloned, and it encoded a protein of 267 amino acid residues with a globular domain. The results of immunohistochemistry and FACS assays showed that APN protein was distributed in multiple tissues. L-APN expression in the supraneural body (SB) and leukocytes was differentially upregulated in response to Gram-negative bacteria, Gram-positive bacteria and poly (I:C). The expression levels of inflammatory cytokines were upregulated, and a proapoptotic effect was stimulated in SB cells treated with recombinant APN. Furthermore, L-APN could inhibit cell proliferation and arrest cell growth in the G1 phase. In summary, the APN protein from the lamprey plays an important role in inhibiting cell proliferation, inducing the production of inflammatory cytokines and promoting cell apoptosis, and it is also involved in immune responses and immune defenses. Our data provide insights into the evolutionary origin of the structure and function of APN gene.

Abstract
Background Simple method to predict type 2 diabetes mellitus (T2DM) combined with chronic obstructive pulmonary disease (COPD) is in great need clinically. This study aims to assess the clinical significance of high‐mobility group box‐1 (HMGB1) in predicting T2DM combined with COPD in Chinese patients with T2DM or COPD. Methods Serum concentrations of glycated hemoglobin (HbA1C), fasting plasma glucose (FPG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low‐density lipoprotein cholesterol (LDL‐c), high‐density lipoprotein cholesterol (HDL‐c), C‐reactive protein (CRP), fibrinogen (FIB), HMGB1, white blood cell count (WBC), neutrophil% (NEU%), and lung function text such as forced expiratory volume 1/forced vital capacity (FEV1/FVC) and forced expiratory volume 1% predicted value (FEV1%pred) were measured in 126 T2DM patients, 118 COPD patients, 112 T2DM combined with COPD patients, and 120 healthy controls. Logistic regression was used to estimate the risk factors for T2DM combined with COPD. Results High‐mobility group box‐1 elevated in patients with T2DM combined with COPD, significantly higher than other subjects (P < 0.05), and differences in HMGB1 also existed between patients with T2DM or COPD and healthy individuals (P < 0.01). HMGB1 was positively correlated with HOMA‐IR, FBG, and HbA1c (P < 0.01) and negatively correlated with FEV1/FVC and FEV1%pred (P < 0.01). Logistic regression showed that HMGB1 was identified to be independent risk factor for T2DM combined with COPD. Conclusion High‐mobility group box‐1 was independent risk factor for T2DM combined with COPD and can be served to predict the occurrence of T2DM combined with COPD.
