Abstract
Sepsis is an unusual systemic reaction with high mortality and secondary septic liver injury is proposed to be the major cause of mortality. Extracorporeal membrane oxygenation (ECMO) can enhance terminal organ perfusion by elevating circulatory support which is used in severe sepsis patients. However, the interaction of blood components with the biomaterials of the extracorporeal membrane elicits a systemic inflammatory response. Besides, inflammation and apoptosis are the main mediators in the pathophysiology of septic liver injury. Therefore, we investigated the protective effect of Deoxyribonuclease I (DNase I) against septic liver injury supported by ECMO in rats. Sepsis was induced by lipopolysaccharide (LPS) and 24 hours after the administration, the rats were treated with ECMO. Then blood samples and liver tissues were collected. DNase I significantly attenuated the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and significantly decreased hepatic levels of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome, myeloperoxidase (MPO), downstream inflammatory factor interleukin-1β (IL-1β) and interleukin-18 (IL-18), and improved neutrophil infiltration. Additionally, DNase I significantly reduced the expression of apoptosis key protein and terminal-deoxynucleotidyl transferase-mediated nick end labeling (TUNEL)-labeled apoptotic hepatocytes. In summary, our findings demonstrated that DNase I alleviates liver injury in ECMO-supported septic rats by reducing the inflammatory and apoptotic responses.

Abstract
BACKGROUND & AIMS Hepatic fibrosis is characterized by enhanced deposition of extracellular matrix (ECM), which results from the wound healing response to chronic, repeated injury of any etiology. Upon injury, hepatic stellate cells (HSCs) activate and secrete ECM proteins, forming scar tissue, which leads to liver dysfunction. Monocyte-chemoattractant protein-induced protein 1 (MCPIP1) possesses anti-inflammatory activity, and its overexpression reduces liver injury in septic mice. In addition, mice with liver-specific deletion of Zc3h12a develop features of primary biliary cholangitis. In this study, we investigated the role of MCPIP1 in liver fibrosis and HSC activation. METHODS We analyzed MCPIP1 levels in patients' fibrotic livers and hepatic cells isolated from fibrotic murine livers. In vitro experiments were conducted on primary HSCs, cholangiocytes, hepatocytes, and LX-2 cells with MCPIP1 overexpression or silencing. RESULTS MCPIP1 levels are induced in patients' fibrotic livers compared with their nonfibrotic counterparts. Murine models of fibrosis revealed that its level is increased in HSCs and hepatocytes. Moreover, hepatocytes with Mcpip1 deletion trigger HSC activation via the release of connective tissue growth factor. Overexpression of MCPIP1 in LX-2 cells inhibits their activation through the regulation of TGFB1 expression, and this phenotype is reversed upon MCPIP1 silencing. CONCLUSIONS We demonstrated that MCPIP1 is induced in human fibrotic livers and regulates the activation of HSCs in both autocrine and paracrine manners. Our results indicate that MCPIP1 could have a potential role in the development of liver fibrosis.

Abstract
As alcohol consumption increases, alcoholic liver disease (ALD) has become more popular and is threating our human life. In this study, we found mulberry fruit extract (MFE) repaired alcohol-caused liver diseases by regulating hepatic lipid biosynthesis pathway and oxidative singling in alcoholically liver injured (ALI) rats. MFE administration inhibited hepatic lipid accumulation and improved liver steatosis in ALI rats. MFE also enhanced the antioxidant capacity and alleviated the inflammatory response by increasing the activities of antioxidant enzymes and decreasing the contents of interleukin (IL)-1β and tumor necrosis factor (TNF)-α. Additionally, MFE regulated the expression of miRNA-155 and lipid metabolism-related PPARα protein in rats. Both miR-155 and PPARα play important roles in liver function. The results indicate that MFE has hepatoprotective effects against ALI in rats.

Abstract
Background Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The liver has a crucial role in sepsis and is also a target for sepsis-related injury. Macrophage polarization between the M1 and M2 types is involved in the progression and resolution of both inflammation and liver injury. Iron oxide-based synthetic nanoparticles (SPIONs) can be used as antibacterial agents to regulate the inflammatory response. Mesenchymal stromal/stem cells (MSCs) have been widely used in the treatment of autoimmune diseases, sepsis, and other diseases. However, to date, both the effects of SPIONs on MSCs and the fate of SPION-labelled MSCs in sepsis and other diseases are still unclear. Methods Mice were subjected to caecal ligation and puncture (CLP) or lipopolysaccharide (LPS) induction to develop sepsis models. The CLP or LPS models were treated with MSCs or SPION-labelled/pretreated MSCs (SPION-MSCs). Bone marrow (BM)-derived macrophages and RAW 264.7 cells were cocultured with MSCs or SPION-MSCs under different conditions. Flow cytometry, transmission electron microscopy, western blotting, quantitative real-time PCR, and immunohistochemical analysis were performed. Results We found that SPIONs did not affect the basic characteristics of MSCs. SPIONs promoted the survival of MSCs by upregulating HO-1 expression under inflammatory conditions. SPION-MSCs enhanced the therapeutic efficacy of liver injury in both the CLP- and LPS-induced mouse models of sepsis. Moreover, the protective effect of SPION-MSCs against sepsis-induced liver injury was related to macrophages. Systemic depletion of macrophages reduced the efficacy of SPION-MSC therapy. Furthermore, SPION-MSCs promoted macrophages to polarize towards the M2 phenotype under sepsis-induced liver injury in mice. The enhanced polarization towards M2 macrophages was attributed to their phagocytosis of SPION-MSCs. SPION-MSC-expressed TRAF1 was critical for promotion of macrophage polarization and alleviation of sepsis in mice. Conclusion MSCs labelled/pretreated with SPIONs may be a novel therapeutic strategy to prevent or treat sepsis and sepsis-induced liver injury. Highlights SPIONs enhance the viability of MSCs by promoting HO-1 expression. SPION-labelled/pretreated MSCs effectively improve sepsis by regulating macrophage polarization to M2 macrophages. SPION-labelled/pretreated MSCs regulate macrophage polarization in a manner dependent on MSC-expressed TRAF1 protein.

Abstract
Monocyte chemoattractant protein-1 induced protein 1 (MCPIP1), one of the MCPIP family members, is characterized by the presence of both C-x8-C-x5-C-x3-H (CCCH)- type zinc finger and PilT-N-terminal domains. As a potent regulator of innate immunity, MCPIP1 exerts anti-inflammatory effects through its ribonuclease (RNase) and deubiquitinating enzyme activities to degrade cytokine mRNAs and inhibit nuclear factor- kappa B (NF-κB), respectively. MCPIP1 is expressed not only in immune cells but also in many other cell types, including cardiomyocytes, vascular endothelial cells (ECs) and smooth muscle cells (SMCs). Increasing evidence indicates that MCPIP1 plays a role in the regulation of cardiac functions and is involved in the processes of vascular diseases, such as ischemia-reperfusion (I/R) and atherosclerosis. To better understand the emerging roles of MCPIP1 in the cardiovascular system, we reviewed the current literature with respect to MCPIP1 functions and discussed its association with the pathogenesis of cardiovascular diseases and the implication as a therapeutic target.

Abstract
Monocyte chemoattractant protein-induced protein 1 (MCPIP1, alias Regnase 1) is a negative regulator of inflammation, acting through cleavage of transcripts coding for proinflammatory cytokines and by inhibition of NFκB activity. Moreover, it was demonstrated that MCPIP1 regulates lipid metabolism both in adipose tissue and in hepatocytes. In this study, we investigated the effects of tissue-specific Mcpip1 deletion on the regulation of hepatic metabolism and development of nonalcoholic fatty liver disease (NAFLD). We used control Mcpip1fl/fl mice and animals with deletion of Mcpip1 in myeloid leukocytes (Mcpip1fl/fl LysMCre ) and in hepatocytes (Mcpip1fl/fl AlbCre ), which were fed chow or a high-fat diet (HFD) for 12 weeks. Mcpip1fl/fl LysMCre mice fed a chow diet were characterized by a significantly reduced hepatic expression of genes regulating lipid and glucose metabolism, which subsequently resulted in low plasma glucose level and dyslipidemia. These animals also displayed systemic inflammation, demonstrated by increased concentrations of cytokines in the plasma and high Tnfa, Il6, IL1b mRNA levels in the liver and brown adipose tissue (BAT). Proinflammatory leukocyte infiltration into BAT, together with low expression of Ucp1 and Ppargc1a, resulted in hypothermia of 22-week-old Mcpip1fl/fl LysMCre mice. On the other hand, there were no significant changes in phenotype in Mcpip1fl/fl AlbCre mice. Although we detected a reduced hepatic expression of genes regulating glucose metabolism and β-oxidation in these mice, they remained asymptomatic. Upon feeding with a HFD, Mcpip1fl/fl LysMCre mice did not develop obesity, glucose intolerance, nor hepatic steatosis, but were characterized by low plasma glucose level and dyslipidemia, along with proinflammatory phenotype. Mcpip1fl/fl AlbCre animals, following a HFD, became hypercholesterolemic, but accumulated lipids in the liver at the same level as Mcpip1fl/fl mice, and no changes in the level of soluble factors tested in the plasma were detected. We have demonstrated that Mcpip1 protein plays an important role in the liver homeostasis. Depletion of Mcpip1 in myeloid leukocytes, followed by systemic inflammation, has a more pronounced effect on controlling liver metabolism and homeostasis than the depletion of Mcpip1 in hepatocytes.

MicroRNA-155: Regulation of Immune Cells in Sepsis. Mediators Inflamm 2021; 2021:8874854.

Abstract
MicroRNAs are small noncoding RNAs which regulate gene expression at the posttranscriptional level. miR-155 is encoded by the miR-155 host gene (miR155HG), also known as the noncoding B cell integration cluster (BIC). MicroRNAs are widely expressed in various hematopoietic cells and are involved in regulating the immune system. In this review, we summarized how miR-155 modulates specific immune cells and the regulatory role of miR-155 in sepsis. miR-155 is expressed by different populations of innate and adaptive immune cells and is involved in the regulation of development, proliferation, and function in these cells. Sepsis is associated with uncontrollable inflammatory responses, accompanied by unacceptably high mortality. Due to the inadequacy of diagnostic markers as well as treatment strategies, treating sepsis can be a huge challenge. So far, a large number of experiments have shown that the expression of miR-155 is increased at an early stage of sepsis and that this increase is positively correlated with disease progression and severity. In addition, by blocking the proinflammatory effects of miR-155, it can effectively improve sepsis-related organ injury, providing novel insights to identify potential biomarkers and therapeutic targets for sepsis. However, since most of the current research is limited to animal experiments, further clinical research is required to determine the function of miR-155 and its mechanism related to sepsis.

Abstract
The role of the inflammation-silencing ribonuclease, MCPIP1 (monocyte chemoattractant protein-induced protein 1), in neoplasia continuous to emerge. The ribonuclease can cleave not only inflammation-related transcripts but also some microRNAs (miRNAs) and viral RNAs. The suppressive effect of the protein has been hitherto suggested in breast cancer, clear cell renal cell carcinoma, osteosarcoma, and neuroblastoma. Our previous results have demonstrated a reduced levels of several oncogenes, as well as inhibited growth of neuroblastoma cells upon MCPIP1 overexpression. Here, we investigate the mechanisms underlying the suppression of MYCN proto-oncogene, bHLH transcription factor (MYCN)-amplified neuroblastoma cells overexpressing the MCPIP1 protein. We showed that the levels of several transcripts involved in cell cycle progression decreased in BE(2)-C and KELLY cells overexpressing MCPIP1 in a ribonucleolytic activity-dependent manner. However, RNA immunoprecipitation indicated that only AURKA mRNA (encoding for Aurora A kinase) interacts with the ribonuclease. Furthermore, the application of a luciferase assay suggested MCPIP1-dependent destabilization of the transcript. Further analyses demonstrated that the entire conserved region of AURKA seems to be indispensable for the interaction with the MCPIP1 protein. Additionally, we examined the effect of the ribonuclease overexpression on the miRNA expression profile in MYCN-amplified neuroblastoma cells. However, no significant alterations were observed. Our data indicate a key role of the binding and cleavage of the AURKA transcript in an MCPIP1-dependent suppressive effect on neuroblastoma cells.

BACKGROUND Mounting evidence, consistent with our previous study, showed that γ-aminobutyric acid type A receptor (GABAAR) played an indispensable role in airway inflammation and mucus hypersecretion in asthma. Monocyte chemotactic protein-inducing protein 1 (MCPIP1) was a key negative regulator of inflammation. Recent studies showed that inflammation was largely suppressed by enhanced MCPIP1 expression in many inflammatory diseases. However, the role and potential mechanism of MCPIP1 in airway inflammation and mucus hypersecretion in asthma were still not well studied. This study was to explore the role of MCPIP1 in asthmatic airway inflammation and mucus hypersecretion in both mice and BEAS-2B cells, and its potential mechanism. METHODS In vivo, mice were sensitized and challenged by ovalbumin (OVA) to induce asthma. Airway inflammation and mucus secretion were analyzed. In vitro, BEAS-2B cells were chosen. Interleukin (IL)-13 was used to stimulate inflammation and mucus hypersecretion in cells. MCPIP1 Lentiviral vector (LA-MCPIP1) and plasmid-MCPIP1 were used to up-regulate MCPIP1 in lung and cells, respectively. MCP-1, thymic stromal lymphopoietin (TSLP), mucin 5AC (MUC5AC), MCPIP1, and GABAARβ2 expressions were measured in both lung and BEAS-2B cells. Immunofluorescence staining was performed to observe the expression of GABAARβ2 in cells. RESULTS MCPIP1 was up-regulated by LA-MCPIP1 (P < 0.001) and plasmid-MCPIP1 (P < 0.001) in lung and cells, respectively. OVA-induced airway inflammation and mucus hypersecretion, OVA-enhanced MCP-1, TSLP, MUC5AC, and GABAARβ2 expressions, and OVA-reduced MCPIP1 were significantly blunted by LA-MCPIP1 in mice (all P < 0.001). IL-13-enhanced MCP-1, TSLP, MUC5AC, and GABAARβ2 expressions, and IL-13-reduced MCPIP1 were markedly abrogated by plasmid-MCPIP1 in BEAS-2B cells (all P < 0.001). CONCLUSION The results of this study suggested that OVA and IL-13-induced airway inflammation and mucus hypersecretion were negatively regulated by MCPIP1 in both lung and BEAS-2B cells, involving GABAAR signaling pathway.
