[PMID: 37667265 PMCID: PMC10476293 DOI: 10.1186/s12944-023-01910-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 08/28/2023] [Indexed: 09/06/2023] Open
Abstract
BACKGROUND Recent studies have shown that loss-of-function mutations in hepatic asialoglycoprotein receptor 1 (ASGR1) are associated with low levels of circulating cholesterol and a reduced risk of coronary artery disease (CAD). In contrast to ASGR1 on the hepatocyte membrane, serum soluble ASGR1 (sASGR1) is a secreted form that has been detected in circulation. However, the functions of serum sASGR1 are unclear. This study aims to investigate the relationship between human serum sASGR1 concentration and low-density lipoprotein cholesterol (LDL-C) levels. METHODS In a cohort of 134 participants who underwent coronary angiography examination, basic information was recorded, and blood samples were collected for biochemical testing. The serum sASGR1 concentration was determined by ELISA kits. The relationship between sASGR1 concentration and LDL-C levels was examined using linear regression models and interaction tests. Univariate and multivariate analyses were used to identify clinical variables that affect sASGR1 levels. RESULTS After adjusting for potential confounders such as age, sex, BMI, and statin use, the serum sASGR1 concentration was positively correlated with LDL-C levels (β = 0.093, 95% CI: 0.04 to 0.14, P < 0.001). Subgroup analysis and interaction tests showed that the effect of serum sASGR1 concentration on LDL-C levels was significantly influenced by hypertension status (P for interaction = 0.0067). The results of a multivariate linear regression analysis incorporating age, serum TG, LDL-C, nonesterified fatty acid (NEFA), white blood cell counts (WBCC), and fibrinogen revealed that LDL-C (β = 1.005, 95% CI: 0.35 to 1.66, P = 0.003) and WBCC (β = 0.787, 95% CI: 0.41 to 1.16, P < 0.0001) were independent influencing factors for serum sASGR1 levels. CONCLUSIONS The serum sASGR1 concentration was positively correlated with LDL-C levels. In addition, hypertension status significantly affected the effect of serum sASGR1 on LDL-C levels. This study provides some research ideas for clinical doctors and researchers, as well as some references for additional research on serum sASGR1.

Abstract
Ammonia (Amm), and its aqueous solved state, ammonium, which is produced from glutamine (Gln) metabolism, is a known inhibitor of stem cell proliferation in vitro. In the context of cultivated beef, primary bovine fibro-adipogenic progenitor cells (FAPs) need to be grown and differentiated for several weeks in vitro for the production of cultivated fat. In this study, the ammonium sensitivity of these cells was investigated by introducing ammonium chloride, which was found to inhibit their proliferation when above 5 mM and their adipogenic differentiation when above 2 mM. Novel serum-free proliferation and differentiation media were hence developed with the aim to suppress Amm production during expansion and adipogenesis. Glutamine substitutes, such as a-ketoglutarate (aKG), glutamate (Glt) and pyruvate (Pyr) were investigated. It was found that aKG based proliferation medium (PM) was the most effective in promoting and maintaining FAPs growth over several passages while the specific Amm production rate was reduced more than 5-fold. In terms of differentiation capacity, the substitution of glucose (Gluc) and Gln with galactose (Gal) and Pyr was shown to be the most effective in promoting FAPs differentiation into mature adipocytes, resulting in over 2-fold increase of fat volume per cell, while suppressing Amm production. Our findings suggest that FAPs do not require Gln as an essential nutrient but, on the contrary, possess all the necessary metabolic pathways to proliferate and subsequently differentiate in a Gln-free medium, resulting in decreased Amm production rates and seemingly synthesising glutamine de novo. These findings are important for prolonging the lifespan of culture medium, allowing for reduced costs and process interventions.

Hepatocyte-Conditional Knockout of Phosphatidylethanolamine Binding Protein 4 Aggravated LPS/D-GalN-Induced Acute Liver Injury via the TLR4/NF-κB Pathway. Front Immunol 2022; 13:901566. [PMID: 35874667 PMCID: PMC9304715 DOI: 10.3389/fimmu.2022.901566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Accepted: 06/13/2022] [Indexed: 12/15/2022] Open
Abstract
Acute liver injury (ALI) is a disease that seriously threatens human health and life, and a dysregulated inflammation response is one of the main mechanisms of ALI induced by various factors. Phosphatidylethanolamine binding protein 4 (PEBP4) is a secreted protein with multiple biological functions. At present, studies on PEBP4 exist mainly in the field of tumors and rarely in inflammation. This study aimed to explore the potential roles and mechanisms of PEBP4 on lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced ALI. PEBP4 was downregulated after treatment with LPS/D-GalN in wild-type mice. PEBP4 hepatocyte-conditional knockout (CKO) aggravated liver damage and repressed liver functions, including hepatocellular edema, red blood cell infiltration, and increased aspartate aminotransferase (AST)/alanine aminotrans-ferase (ALT) activities. The inflammatory response was promoted through increased neutrophil infiltration, myeloperoxidase (MPO) activities, and cytokine secretions (interleukin-1β, IL-1β; tumor necrosis factor alpha, TNF-α; and cyclooxygenase-2, COX-2) in PEBP4 CKO mice. PEBP4 CKO also induced an apoptotic effect, including increasing the degree of apoptotic hepatocytes, the expressions and activities of caspases, and pro-apoptotic factor Bax while decreasing anti-apoptotic factor Bcl-2. Furthermore, the data demonstrated the levels of Toll-like receptor 4 (TLR4), phosphorylation-inhibitor of nuclear factor kappaB Alpha (p-IκB-α), and nuclear factor kappaB (NF-κB) p65 were upregulated, while the expressions of cytoplasmic IκB-α and NF-κB p65 were downregulated after PEBP4 CKO. More importantly, both the NF-κB inhibitor (Ammonium pyrrolidinedithiocarbamate, PDTC) and a small-molecule inhibitor of TLR4 (TAK-242) could inhibit TLR4/NF-κB signaling activation and reverse the effects of PEBP4 CKO. In summary, the data suggested that hepatocyte-conditional knockout of PEBP4 aggravated LPS/D-GalN-induced ALI, and the effect is partly mediated by activation of the TLR4/NF-κB signaling pathway.

Abstract
Acute liver injury is a serious clinical syndrome with multiple causes and unclear pathological process. Here, CCl4‐ and D‐galactosamine/lipopolysaccharide (D‐gal/LPS)‐induced acute liver injury was established to explore the cell death patterns and determine whether or not liver regeneration occurred. In CCl4‐induced hepatic injury, three phases, including the early, progressive, and recovery phase, were considered based on alterations of serum transaminases and liver morphology. Moreover, in this model, cytokines exhibited double‐peak fluctuations; apoptosis and pyroptosis persisted throughout all phases; autophagy occurred in the early and the progressive phases; and sufficient and timely hepatocyte regeneration was observed only during the recovery phase. All of these phenomena contribute to mild liver injury and subsequent regeneration. Strikingly, only the early and progressive phases were observed in the D‐gal/LPS model. Slight pyroptosis occurred in the early phase but diminished in the progressive phase, while apoptosis, reduced autophagy, and slight but subsequently diminished regeneration occurred only during the progressive phase, accompanied by a strong cytokine storm, resulting in severe liver injury with high mortality. Taken together, our work reveals variable modes and dynamics of cell death and regeneration, which lead to different consequences for mild and severe acute liver injury, providing a helpful reference for clinical therapy and prognosis.

Abstract
Inflammatory cytokine storm is one of the main pathogenesis of acute liver injury, and accumulating evidence suggests that the E3 ubiquitin ligase ring finger protein 31 (RNF31) plays an important regulatory role in the activation of inflammatory pathways. We found that RNF31 expression was up-regulated in lipopolysaccharide (LPS)-treated HL-7702 cells. Western blotting results showed decreased expression of RNF31 and total ubiquitinated proteins after transfection of si-RNF31. The results of MTT assay indicated that cell viability was enhanced. Flow cytometry analysis showed that cell apoptosis and ROS content was decreased, and ELISA assay results exhibited that the inflammatory factors secretion was reduced. Interestingly, A20 protein expression was inhibited as RNF31 expression was upregulated. On this basis, we performed co-immunoprecipitation assays and found that RNF31 could interact with A20. Actinomycin tracing and proteasome inhibition experiments showed that RNF31 degrades A20 through the proteasome pathway. Furthermore, overexpression of A20 enhanced cell viability, reduced apoptosis, and inhibited ROS generation and inflammatory factor secretion. Mechanistic studies revealed that RNF31 was able to degrade A20, which affected the inflammatory response and hepatocyte apoptosis mediated by the toll like receptor 4 (TLR4)/myeloid differentiation factor88 (MyD88)/nuclear transcription factor-κB (NF-κB) signaling pathway. Moreover, knockdown of RNF31 attenuated the inflammatory response induced by d-Gal/LPS in mice with acute liver injury. In conclusion, RNF31 degrades A20 by ubiquitination and activates the TLR4/MyD88/NF-κB signaling pathway to aggravate acute liver injury.

Abstract
Acute liver injury and its terminal phase, hepatic failure, trigger a series of complications, including hepatic encephalopathy, systematic inflammatory response syndrome, and multiorgan failure, with relatively high morbidity and mortality. Liver transplantation is the ultimate intervention, but the shortage of donor organs has limited clinical success. Mangiferin (MF), a xanthone glucoside, has been reported to have excellent anti-inflammatory efficacy. Here, a lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute liver injury mouse model was established to investigate the protective role of MF and the underlying mechanisms of action. Pretreatment with MF improved survival, decreased serum aminotransferase activities, and inhibited hepatic TNF-α production in LPS/D-GalN-challenged mice. Through Kupffer cell (KC) deletion by GdCl3 and KC adoptive transfer, KCs were confirmed to be involved in these beneficial effects of MF. MF reduced LPS-mediated TNF-α production via the suppression of the TLR4/NF-κB signaling pathway in vitro. MF promoted HO-1 expression, but the knockdown of HO-1 prevented TNF-α inhibition, suggesting that the damage-resistance effects of HO-1 occurred via the suppression of TNF-α synthesis. When HO-1-silenced KCs were transferred to the liver with KC deletion, the protective effect of MF against LPS/D-GalN-induced acute liver injury was reduced, illustrating the role of KC-derived HO-1 in the anti-injury effects of MF. Collectively, MF attenuated acute liver injury induced by LPS/D-GalN via the inhibition of TNF-α production by promoting KCs to upregulate HO-1 expression.

Abstract
Urolithin A, a metabolite produced by human colon microflora from ellagic acid and related compounds, has been reported to have antioxidant, anti-inflammatory and antiapoptotic properties. The present study investigates the protective effects of urolithin A (Uro A) on d-galactose (d-gal)-induced liver and kidney injury and the possible mechanisms in mice. In this study, we first investigated the antioxidant ability of Uro A in vitro. Then mice were treated with d-gal subcutaneously (150 mg kg-1 d-1), followed by Uro A at different dosages (50, 100, 150 mg kg-1 d-1, administered orally) for 8 weeks. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine (Cr) in the serum were tested. Histopathological features were assessed by hematoxylin and eosin (HE) staining followed by an assessment of the antioxidant and anti-inflammatory activities. Furthermore, we also evaluated the expression levels of the genes Bax, Bcl-2 and cleaved caspase-3 in the liver and kidney. The results showed that Uro A treatment obviously attenuated d-gal-induced liver and kidney damage. The beneficial effects of Uro A were accompanied by a decline in malondialdehyde (MDA) levels and a rise in the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and total antioxidant capacity (T-AOC) activity in the liver and kidney and downregulation of the levels of inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6), in serum. Moreover, Uro A could modulate the expression of Bax, Bcl-2 and cleaved caspase-3 in the livers and kidneys of aging mice. These findings suggested that Uro A ameliorated d-gal-induced liver and kidney injury through attenuating oxidative stress, inflammatory responses and apoptosis.

Abstract
The liver is an important digestive gland, and acute liver failure results in high mortality. Probiotics are considered potential adjuvant therapies for liver disease. This study aimed to investigate the beneficial effects of Lactobacillus helveticus R0052 on acute liver injury and the underlying mechanisms. Sprague-Dawley rats were gavaged with L. helveticus R0052 suspensions (3 × 109 CFU) for 1 week. Subsequently, acute liver injury was induced by intraperitoneal D-galactosamine injection on the eighth day. After 24 h, samples (blood, liver, ileum, faeces) were collected and assessed for histological injury, inflammation, intestinal barrier, gut microbiome and metabolome. L. helveticus R0052 alleviated aminotransferase, bilirubin and total bile acid elevation and histological hepatic injuries. Additionally, L. helveticus R0052 exhibited anti-inflammatory properties by downregulating Toll-like receptors, tumour necrosis factor-α and nuclear factor-κb transcription in liver samples and decreasing proinflammatory cytokine plasma concentrations. Additionally, L. helveticus R0052 ameliorated intestinal abnormalities and regulated Toll-like receptors, claudin2 and mucin3 gene transcription in the intestine. These effects were associated with gut microbiome and metabolome modulation by L. helveticus R0052. Probiotic pretreatment enriched Lactobacillus and Bacteroides and depleted Flavonifractor and Acetatifactor in the gut microbiome. Meanwhile, L. helveticus R0052 improved carbohydrate and fatty acid metabolism and reduced lithocholic acid levels. These results indicate that L. helveticus R0052 is promising for alleviating acute liver injury and provide new insights regarding the correlations among the microbiome, the metabolome, the intestinal barrier and liver disease.

Abstract
Wushan Shencha (Malus doumeri leaf) is a unique tea-like drink. Herein, the effect of flavonoids from Wushan Shencha (FWSSC) on carbon tetrachloride-induced liver injury was studied. The serum and liver tissues of experimental mice were analyzed by kits, a slice technique, and qPCR assay. The liver index is a calculated liver-to-body weight ratio, and the experimental results showed that FWSSC reduced the liver index of the model group with liver injury, which was the highest. Sections stained with H&E showed that FWSSC reduced stem cell necrosis caused by liver injury. FWSSC reduced the serum levels of AST, ALT, TG, and TC, as well as the levels of IL-6, TNF-α, and IFN-γ cytokines in the serum of mice with liver injury. Liver biochemical tests also showed that FWSSC increased the SOD activity and decreased TC, TG, and MPO levels in mice with liver injury. It was found that FWSSC upregulated the expression of Cu/Zn-SOD, Mn-SOD, CAT, and IκB-α, and downregulated the expression of NF-κB, COX-2, TNF-α, and IL-1β in the liver tissue of mice with liver injury by detecting the expression of mRNA in liver tissue. It is concluded that FWSSC is an active substance with hepatoprotective effects. The activity of FWSSC increased with increasing concentration, and the hepatoprotective effect of FWSSC at 100 mg/kg concentration was stronger than that of silymarin.

J Diabetes Complications 2019; 33:539-546. [PMID: 31202960 DOI: 10.1016/j.jdiacomp.2019.05.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 04/22/2019] [Accepted: 05/11/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND The ASGR1 was recently shown to play a key role in the development of coronary artery disease (CAD), but its exact mechanism of action in the CAD pathogenesis is not yet known. This study evaluates the possible association between the expression level of ASGR1 and its downstream transcription factor FOXM1 in the inflammatory cells of peripheral blood (PBMC) and the pathogenesis of CAD in the Diabetic condition. METHODS Blood samples were taken from the candidates who had visited the Tehran Heart Center and had underwent diagnostic tests with respect to diabetes and CAD. The peripheral blood cells were harvested, RNA was extracted, and cDNA was synthesized. The qRT-PCR was performed on 79 cDNA samples taken from 49 CAD+ patients and 30 CAD- patients. RESULTS In this study, we observed a significant decrease of ASGR1 expression in the PBMC of CAD+ patients compared to the CAD- patients. We did not identify any considerable differences in the expression of FOXM1 in patients' subgroups with respect to the diabetes and CAD. CONCLUSION The results of our study determine the association of ASGR1 expression and CAD pathogenesis. However, we do not know whether this result is the cause or the effect of CAD.

Abstract
Acute-on-chronic liver failure (ACLF) carries a significant burden on critical care services and health care resources. However, the exact pathogenesis of ACLF remains to be elucidated, and novel treatments are desperately required. In our previous work, we utilized mice subjected to acute insult in the context of hepatic fibrosis to simulate the development of ACLF and documented the favorable hepatoprotection conferred by M2-like macrophages in vivo and in vitro. In the present study, we focused on the phenotypic switch of human and mouse macrophages and assessed the effects of this switch on apoptosis resistance in hepatocytes. For this purpose, human and mouse macrophages were isolated and polarized into M0, M(IFN-γ), M(IFN-γ→IL-4), M(IL-4) or M(IL-4→IFN-γ) subsets. Conditioned media (CM) from these subsets were applied to human and mouse hepatocytes followed by apoptosis induction. Cell apoptosis was evaluated by immunostaining for cleaved caspase-3. As a result, M(IFN-γ) or M(IL-4) macrophages switched their phenotype into M(IFN-γ→IL-4) or M(IL-4→IFN-γ) through reprogramming with IL-4 or IFN-γ, respectively. Importantly, hepatocytes pre-treated with M(IFN-γ→IL-4) CMs exhibited much weaker expression of cleaved caspase-3, compared to those pre-treated with M(IFN-γ) CM, and vice versa. Together, phenotypic switch of macrophages toward M(IL-4) phenotype confers hepatocytes enhanced resistance to apoptosis.

Abstract
AIM To investigate the correlation between expression of cytokines and preventive effects of Zhige oral solution against alcoholic liver injury (ALI) in rats.
METHODS Rats were divided into six groups: normal control group, model group, positive control group, high-, medium-, and low-dose Zhige oral solution groups. Except the normal control group, ALI was induced in rats of other groups by simple alcohol gavage. The high-, medium-, and low-dose Zhige oral solution groups were given high-, medium- and low-dose group Zhige oral solution, the positive control group was given Jiejiuling oral solution, and the normal control group was given distilled water. Twelve weeks later, abdominal aorta arterial blood was collected to measure serum levels of alanine transaminase (ALT) and aspartate transaminase (AST), as well as the contents of serum tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-10. The rats were sacrificed to observe the pathological changes in liver tissue.
RESULTS Compared with the normal control group, serum levels of TNF-α, IL-6, IL-10, ALT, and AST were significantly altered in all groups except the high-dose Zhige oral solution group (P < 0.01 or 0.05), and varying degrees of massive swelling of liver cells and red lipid droplets were observed in liver tissues in all groups. Compared with the model group, all the tested indicators showed varying degrees of reversal in the positive control group and three intervention groups (P < 0.01 or 0.05), and the reversal effect was best in the high-dose Zhige oral solution group (P < 0.01). The therapeutic effect in the middle dose group was similar to that in the positive control group (P > 0.05).
CONCLUSION Zhige oral solution can reduce or inhibit the occurrence of ALI by regulating the levels of cytokines in rats.

Abstract
Tumor necrosis factor-α (TNF-α), an important factor in systematic inflammation, is reportedly involved in several cancer types. The TNF-α -308 G>A (rs1800629) polymorphism in the promoter region influences TNF-α production. The association between TNF-α -308 G>A polymorphism and colorectal cancer (CRC) is not fully understood, especially the connections between TNF-α -308 G>A polymorphism and clinical features of CRC. In this study, TNF-α -308 G>A polymorphism was genotyped in 1140 individuals with or without CRC from Southwestern China. In case-control studies, we found no association between TNF-α -308 G>A polymorphism and CRC risk. Analysis of the correlations between TNF-α -308 G>A polymorphism and clinical features of CRC revealed that TNF-α -308 A allele was associated with higher body mass index (BMI) larger tumor size, and distant tumor metastasis in all CRC patients. Notably, rectal cancer (a subtype of CRC) patients with TNF-α -308 A allele had a very high risk of distant tumor metastasis [odds ratio (OR) = 4.481; 95% confidence interval (CI): 2.072–9.693; P = 0.00025]. The association between TNF-α -308 A allele and distant tumor metastasis remained even significant after adjusting all clinical characteristics (OR = 7.099; 95% CI: 2.482–20.301; P = 0.000256) in rectal cancer patients. Our results suggested that TNF-α -308 A allele was significantly associated with distant tumor metastasis in rectal cancer patients.

Abstract
AIM To determine the impact of selected well defined Helicobacter pylori (H. pylori) antigens on gastric barrier cell turnover.
METHODS In this study, using two cellular models of gastric epithelial cells and fibroblasts, we have focused on exploring the effects of well defined H. pylori soluble components such as glycine acid extract antigenic complex (GE), subunit A of urease (UreA), cytotoxin associated gene A protein (CagA) and lipopolysaccharide (LPS) on cell turnover by comparing the wound healing capacity of the cells in terms of their proliferative and metabolic activity as well as cell cycle distribution. Toxic effects of H. pylori components have been assessed in an association with damage to cell nuclei and inhibition of signal transducer and activator of transcription 3 (STAT3) phosphorylation.
RESULTS We showed that H. pylori GE, CagA and UreA promoted regeneration of epithelial cells and fibroblasts, which is necessary for effective tissue healing. However, in vivo increased proliferative activity of these cells may constitute an increased risk of gastric neoplasia. In contrast, H. pylori LPS showed a dose-dependent influence on the process of wound healing. At a low concentration (1 ng/mL) H. pylori LPS accelerated of healing epithelial cells, which was linked to significantly enhanced cell proliferation and MTT reduction as well as lack of alterations in cell cycle and downregulation of epidermal growth factor (EGF) production as well as cell nuclei destruction. By comparison, H. pylori LPS at a high concentration (25 ng/mL) inhibited the process of wound repair, which was related to diminished proliferative activity of the cells, cell cycle arrest, destruction of cell nuclei and downregulation of the EGF/STAT3 signalling pathway.
CONCLUSION In vivo H. pylori LPS driven effects might lead to the maintenance of chronic inflammatory response and pathological disorders on the level of the gastric mucosal barrier.
