Abstract
Keloids, marked by abnormal cellular proliferation and excessive extracellular matrix (ECM) accumulation, pose significant therapeutic challenges. Ethyl pyruvate (EP), an inhibitor of the high-mobility group box 1 (HMGB1) and TGF-β1 pathways, has emerged as a potential anti-fibrotic agent. Our research evaluated EP's effects on keloid fibroblast (KF) proliferation and ECM production, employing both in vitro cell cultures and ex vivo patient-derived keloid spheroids. We also analyzed the expression levels of ECM components in keloid tissue spheroids treated with EP through immunohistochemistry. Findings revealed that EP treatment impedes the nuclear translocation of HMGB1 and diminishes KF proliferation. Additionally, EP significantly lowered mRNA and protein levels of collagen I and III by attenuating TGF-β1 and pSmad2/3 complex expression in both human dermal fibroblasts and KFs. Moreover, metalloproteinase I (MMP-1) and MMP-3 mRNA levels saw a notable increase following EP administration. In keloid spheroids, EP induced a dose-dependent reduction in ECM component expression. Immunohistochemical and western blot analyses confirmed significant declines in collagen I, collagen III, fibronectin, elastin, TGF-β, AKT, and ERK 1/2 expression levels. These outcomes underscore EP's antifibrotic potential, suggesting its viability as a therapeutic approach for keloids.

Int Immunopharmacol 2024; 129:111538. [PMID: 38306830 DOI: 10.1016/j.intimp.2024.111538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 01/03/2024] [Accepted: 01/10/2024] [Indexed: 02/04/2024]
Abstract
CCl4-induced acute liver injury (ALI) is characterized by heightened autophagy, inflammation, and oxidative damage. Accumulating evidence suggests that harmine exerts beneficial effects in countering CCl4-induced ALI by mitigating inflammation and oxidative stress. However, the impact of autophagy on CCl4-induced ALI and the protective role of harmine remain unclear. This study aimed to investigate the potential protective effects of harmine against CCl4-induced ALI in mice by suppressing autophagy and inflammation. Male Kunming mice were orally administered harmine or bifendate for seven days. Subsequently, one hour after the final administration, the model group and treatment groups were intraperitoneally injected with CCl4 to induce ALI. The findings revealed that harmine significantly reduced the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum, and ameliorated the liver histopathological changes induced by CCl4. Furthermore, harmine diminished the levels of TNF-α and IL-6, restored the levels of glutathione (GSH) and superoxide dismutase (SOD), and suppressed the production of nitric oxide (NO) and malondialdehyde (MDA) in the liver. Mechanistically, harmine down-regulated LC3B II/I, p38 MAPK, TLR4, and NF-κB levels, while upregulating p62, Bcl-2, Beclin1, ULK1, and p-mTOR expression. In conclusion, harmine mitigated CCl4-induced ALI by inhibiting autophagy and inflammation through the p38 MAPK/mTOR autophagy pathway, the Bcl-2/Beclin1 pathway, and the TLR4/NF-κB pathway.

A polysaccharide from Codonopsis pilosula roots attenuates carbon tetrachloride-induced liver fibrosis via modulation of TLR4/NF-κB and TGF-β1/Smad3 signaling pathway. Int Immunopharmacol 2023; 119:110180. [PMID: 37068337 DOI: 10.1016/j.intimp.2023.110180] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 03/22/2023] [Accepted: 04/10/2023] [Indexed: 04/19/2023]
Abstract
The present work reported the extraction, purification, characterization of a polysaccharide from roots of Codonopsis pilosula (CPP-A-1) and its effect on liver fibrosis. The findings exhibited that the molecular weight of CPP-A-1 was 9424 Da, and monosaccharide composition were glucose and fructose and minor contents of arabinose. Structural characterization of CPP-A-1 has a backbone consisting of→(2-β-D-Fruf-1)n→ (n ≈ 46-47). Treatment with CPP-A-1 inhibited the proliferation of transforming growth factor-beta 1 (TGF-β)-activated human hepatic stellate cell line (LX-2), and induced cell apoptosis. We used carbon tetrachloride (CCl4) to construct mice model of liver fibrosis and subsequently administered CPP-A-1 treatment. The results showed that CPP-A-1 alleviated CCl4-induced liver fibrosis as demonstrated by reversing liver histological changes, decreased serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) contents, collagen deposition, and downregulated fibrosis-related collagen I and α-smooth muscle actin (α-SMA), and inhibited the generation of excessive extracellular matrix (ECM) components by restoring the balance between matrix metalloproteinases (MMPs) and its inhibitor (TIMPs). Moreover, CPP-A-1 improved anti-oxidation effects detected by promoting liver superoxide dismutase (SOD), glutathione (GSH) and Mn-SOD levels, and inhibition of liver malondialdehyde (MDA) and iNOS levels. CPP-A-1 also ameliorated the inflammatory factor (tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6), and expression of inflammatory factor genes (TNF-α, IL-11 mRNA). In addition, our results showed that CPP-A-1 inhibited Toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NF-κB) and transforming growth factor-β1 (TGF-β1)/drosophila mothers against decapentaplegic 3 (Smad3) signaling pathways. Furthermore, In vitro tests of LX-2 cells demonstrated that CPP-A-1 not only inhibited α-SMA expression with lipopolysaccharide (LPS) or TGF-β1 stimulation, but also inhibited TLR4/NF-κB and TGF-β1/Smad3 signaling, similar to corresponding small-molecule inhibitors. Therefore, CPP-A-1 might exert suppressive effects against liver fibrosis by regulating TLR4/NF-κB and TGF-β1/Smad3 signaling, our findings support a possible application of CPP-A-1 for the treatment of liver fibrosis.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 303:115992. [PMID: 36509261 DOI: 10.1016/j.jep.2022.115992] [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: 07/02/2022] [Revised: 11/20/2022] [Accepted: 11/25/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alternanthera brasiliana L. is a flowering plant belonging to the family Amaranthaceae and is popularly known as "penicillin". It is used in folk medicine to treat infections, coughs, wound healing, and inflammatory diseases. AIM OF THE STUDY We investigated the effect of Alternanthera brasiliana L. leaves hydroalcoholic extract (AB) against oxidative stress, inflammation, and fibrotic changes in an experimental model of carbon tetrachloride (CCl4)-induced liver injury and fibrosis in mice. MATERIALS AND METHODS Thirty-six male Balb/C mice were randomized into five groups: normal control, AB control, CCl4 control, CCl4 + AB-200 mg/kg, and CCl4 + AB-400 mg/kg. In mice, liver injury was induced by intraperitoneal injection of CCl4 (20% in corn oil, 5 ml/kg body weight) thrice a week for six consecutive weeks. AB extract at two doses (200 mg/kg and 400 mg/kg body weight) was administered orally for six consecutive weeks. Liver injury-related serum markers (ALT, AST, ALP), antioxidants (GSH, GST, SOD, and vitamin C), pro-inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-18, ultrasonographic and histological alterations, proteins of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinase-1 (TIMP-1), nuclear factor-κB (p65) (NF-κB), nod-like receptor protein 3 (NLRP3), and TGF-β/Smad signaling were accessed. LC-Q-TOF-MS/MS analysis of AB was performed. RESULTS AB treatment significantly decreased the CCl4-induced rise in serum ALT, AST, and ALP activities and improved the histological alterations. Compared with the CCl4-treated group, treatment with AB significantly restored the hepatic antioxidants and reduced the pro-inflammatory cytokines in the liver. The antioxidant activity of AB may be attributed to its terpenoid constituents, which was confirmed by LC-Q-TOF-MS/MS analysis. The CCl4-induced rise in expression of MMP-2 and MMP-9 and decrease in TIMP-1 were markedly restored in the AB-treated groups. Further findings revealed a significant reduction in the protein levels of phospho-NF-κB (p65), NLRP3, TGF-β, pSmad2/3, collagen I, and α-smooth muscle actin (α-SMA) in the AB treatment groups. CONCLUSIONS The hepatoprotective effect of AB may be attributed to the high content of terpenoid compounds and alleviates liver injury and associated fibrotic changes through modulating MMPs, NF-κB (p65), and the TGF-β/Smad axis.

Abstract
Acute liver injury is a common and serious syndrome caused by multiple factors and unclear pathogenesis. If the injury persists, liver injury can lead to cirrhosis and liver failure and ultimately results in the development of liver cancer. Emerging evidence has indicated that long noncoding RNAs (lncRNAs) play an important role in the development of liver injury. However, the role of antisense Igf2r RNA (Airn) in acute liver injury and its underlying mechanism remain largely unclear. In this study, we show that Airn is upregulated in liver tissue and primary hepatocytes from an acute liver injury mouse model. Consistently, Airn is also overexpressed in serum samples of patients with acute-on-chronic liver failure and is negatively correlated with the Model for End-Stage Liver Disease (MELD) score. Moreover, gene knockout and rescue assays reveal that Airn alleviates CCl 4-induced liver injury by inhibiting hepatocyte apoptosis and oxidative stress in vivo. Further investigation reveals that Airn decreases H 2O 2-induced hepatocyte apoptosis in vitro. Mechanistically, we reveal that Airn represses CCl 4- and H 2O 2-induced enhancement of phosphorylation of p65 and IκBα, suggesting that Airn inhibits hepatocyte apoptosis by inactivating the NF-κB pathway. In conclusion, our results demonstrate that Airn can alleviate acute liver injury by inhibiting hepatocyte apoptosis via inactivating the NF-κB signaling pathway, and Airn could be a potential biomarker for acute liver injury.

Abstract
Ischemia-reperfusion injury (IRI) is a process whereby an initial ischemia injury and subsequent recovery of blood flow, which leads to the propagation of an innate immune response and the changes of structural and functional of multiple organs. Therefore, IRI is considered to be a great challenge in clinical treatment such as organ transplantation or coronary angioplasty. In recent years, ethyl pyruvate (EP), a derivative of pyruvate, has received great attention because of its stability and low toxicity. Previous studies have proved that EP has various pharmacological activities, including anti-inflammation, anti-oxidative stress, anti-apoptosis, and anti-fibrosis. Compelling evidence has indicated EP plays a beneficial role in a variety of acute injury models, such as brain IRI, myocardial IRI, renal IRI, and hepatic IRI. Moreover, EP can not only effectively inhibit multiple IRI-induced pathological processes, but also improve the structural and functional lesion of tissues and organs. In this study, we review the recent progress in the research on EP and discuss their implications for a better understanding of multiple organ IRI, and the prospects of targeting the EP for therapeutic intervention.

Abstract
Intrauterine adhesion (IUA) is a disease characterized by endometrial fibrosis caused by injury to the endometrium. In the present study, decellularized and lyophilized human amniotic membrane (DL-AM) material was transplanted in a rat model to explore the preventive effect against IUA. A total of 24 Sprague Dawley rats were randomly divided into an IUA (n=12) group and an IUA + DL-AM (n=12) group. To establish the model, the endometrium of the left uterus was scraped, while that of the right uterus was used as a control. In the IUA group, scraped uteri were sutured without any other treatment, whereas DL-AM was transplanted onto the scraped uteri in the IUA + DL-AM group. Uteri were resected for histological and immunohistochemical evaluation at 3, 7, 14 and 28 days after surgery. The results confirmed the development of IUA, which was accompanied by an increase in the rate of fibrotic area. Integral optical density (IOD) values of connective tissue growth factor (CTGF) were elevated in the IUA group, while matrix metalloproteinase-2 (MMP-2) decreased relative to the control group (P<0.05). After DL-AM transplantation, the IOD value of CTGF dropped, while MMP-2 increased compared with the IUA group (P<0.05). However, compared with that in the control group, the IOD value of CTGF was still higher, whereas MMP-2 was still lower in the IUA + DL-AM group (P<0.05). Furthermore, no evidence of endometrial regeneration was detected in both the IUA and IUA + DL-AM groups. Overall, these results indicated that in the rat model of IUA, transplantation of DL-AM had the potential to prevent the formation of fibrosis to a certain extent and may thus be an alternative strategy for managing the condition.

Abstract
Background/aim Acetaminophen (APAP), used in the composition of thousands of preparations, is the most commonly used analgesic and antipyretic drug. The present study aimed to investigate the potential protective effects of the betulinic acid (BA) treatment through an APAP-induced hepatotoxicity rat model, using inflammatory, biochemical, and histopathological parameters. Materials and methods The study consisted of four groups: control group, APAP group, BA group, and APAP+BA group. Experimental studies continued for fifteen days. Serum samples were analysed for glucose, total cholesterol (TChol), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), aspartate amino transferase (AST), malondialdehyde (MDA), toll-like receptor-9 (TLR-9), nuclear factor kappa B (NF-κB), and interleukin-18 (IL-18). Results TLR9, IL-18, NF-κB, and MDA levels increased significantly in liver injury groups. These increases considerably decreased by the BA treatment. All groups showed immunopositivity for 8-hydroxy-2’–deoxyguanosine (8-OHdG) and interleukin (IL-1β) in the hepatocytes, inflammatory cells, and epithelial cells of bile ducts. Conclusion BA can be used as an effective agent in the prevention and treatment of acute liver diseases due to its inhibitory properties in multiple pathways and its potent antioxidant effects.

Abstract
Natural polysaccharides and their derivatives have attracted academic attention due to their extensive physiological activities. However, the hepatoprotective effects against carbon tetrachloride (CCl4) toxicity have not been well elucidated. The objectives of this study were to characterize the structural properties of sulfated Ganoderma applanatum residue polysaccharides (SGRP) and to evaluate their inhibitory effects on liver fibrosis caused by oxidative stress and inflammation. Our in vivo study showed that SGRP was hepatoprotective in CCl4-induced chronic liver injury mice. It reduced the histopathological damages, down-regulated CYP2E1 (cytochrome P450 2E1) expression, reduced serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, improved the anti-oxidative and anti-inflammatory properties, inhibited TLR4/NF-κB signaling pathway, and reduced the release of inflammatory cytokines. The structural studies indicated that SGRP is a heteropolysaccharide with 7.8% sulfur content and α-linked residue. Our study projects SGRP as a potential candidate in anti-fibrosis treatment by using it as a food supplement or in medicines produced by pharmaceutical industries.

Abstract
Myocardial fibrosis (MFs) is a crucial pathological process that results in cardiac failure in the development of multiple cardiovascular diseases. Puerarin could reportedly be used to treat a variety of cardiovascular diseases. However, the exact mechanism of puerarin on MFs was not clear enough. The separated primary cardiac fibroblasts (CFs) were induced by lipopolysaccharide (LPS) and treated with puerarin. The levels of TNF-α, IL-6, HMGB1, PARP-1, α-SMA, collagen-1, collagen-3, NF-κB pathways were examined by ELISA, immunofluorescence, RT-qPCR, western blot and immunohistochemistry assays. In addition, MFs rats' model was established using transverse aortic constriction (TAC), and the degree of fibrosis was certified by masson staining. We successfully separated primary CFs, and certified that LPS induction could upregulate the levels of PARP-1, HMGB1, inflammatory cytokines and fibrosis-related proteins (α-SMA, collagen-1 and collagen-3). In addition, we proved that puerarin could weaken MFs, and PARP-1 and HMGB1 expressions, which were induced by LPS in primary CFs. In terms of mechanism, HMGB1 expression could be promoted by PARP-1, and PARP-1 could attenuate the therapeutic effect of puerarin on LPS-induced MFs. Besides, PARP-1-HMGB1-NF-κB pathway was related to the protective effect of puerarin on MFs. In vivo, we also verified the protective efficacy of puerarin on MFs induced by TAC, and puerarin also regulated HMGB1-mediated TLR4-NF-κB signaling pathway. We demonstrated that puerarin could ameliorate MFs by downregulating PARP-1 to inhibit HMGB1-mediated TLR4-NF-κB signaling pathway in LPS-induced primary CFs and TAC-induced MFs rats' model.

Abstract
Hepatic stellate cell (HSC) activation is a crucial event in the progress of liver fibrosis. In this study, the target of helenalin was firstly predicted by bioinformatics analysis, and then the prediction was verified by various experiments. HSC-T6 cells were activated by interleukin-1 beta (IL-1β) and then treated with helenalin. Moreover, HSC-T6 cells were transfected with miR-200a mimic or inhibitor, and the effect of helenalin on the miR-200a-mediated PI3K/Akt and NF-κB signaling pathways was investigated. The bioinformatics analysis indicated that miR-200a might regulate the PI3K/Akt pathway, NF-κB activation, Bcl-2 family and Caspases, ultimately affecting cell survival and apoptosis. Interestingly, the molecular docking demonstrated that the target of helenalin might be miR-200a-mediated the PI3K/Akt and NF-κB pathways. Moreover, the experiments showed that helenalin administration led to the inactivation of HSC-T6 cells, as evidenced by the inhibition of cell proliferation, α-SMA expression and collagen production. The mechanism studies showed that helenalin reduced collagen accumulation by restoring the balance of MMPs/TIMPs. Moreover, helenalin markedly suppressed HSC activation by inhibiting the PI3K/Akt pathway and alleviated inflammatory response by blocking the NF-κB signal transduction. Further study indicated that helenalin up-regulated miR-200a expression, thus leading to the inhibition of the PI3K/Akt and NF-κB signaling pathways. In conclusion, helenalin inhibits HSC activation via inhibiting the miR-200a-mediated PI3K/Akt and NF-κB pathways, and it may be developed as a potential medicine for the treatment of liver fibrosis.

Abstract
Context: Sanguisorba officinalis L. (Rosaceae), a famous traditional Chinese medicine. It was recently reported that its polysaccharide could facilitate collagen production.Objectives: We investigated the mechanism by which S. officinalis polysaccharide (SOWPa) and/or platelet-rich plasma (PRP) promote regenerative potential of anterior cruciate ligament (ACL) in vitro.Materials and methods: ACL fibroblasts were treated with SOWPa (25 and 100 mg/kg), PRP, PRP + SOWPa (25 and 100 mg/kg) or vehicle alone for 24, 48, or 72 h. Cell viability, migration ability and apoptosis were evaluated by MTT, transwell and flow cytometry, respectively. Western blot analysis was performed to assess associated protein expression.Results: PRP, SOWPa (100 mg/kg) or PRP + SOWPa (100 mg/kg) treatment for 72 h significantly improved the cell viability of ACL fibroblasts from 100 ± 7.5% (control) to 156.85 ± 12.82%, 188.08 ± 15.92%, and 223.67 ± 18.82%, respectively, which was evidenced by individual decreased apoptosis rate from 31.26 ± 2.35% (control) to 20.80 ± 1.89%, 18.01 ± 1.55% and 9.33 ± 0.78%. Furthermore, the motility of ACL fibroblasts was significantly improved with increased migrated cell number per field from 5 for control to 26 for PRP, 36 for SOWPa and 44 for PRP + SOWPa, respectively. Moreover, the protein expression of differentiation markers (RUNX2, ALP, BMP2 and Col I) and TLR-4 and phosphorylated p65 (p-p65) was inhibited by the above treatment.Discussion and conclusions: Data suggested that the addition of SOWPa to PRP increased the regenerative ability of ACL fibroblasts by blocking the TLR-4/NF-κB pathway.

Abstract
Liver fibrosis results from chronic damages together with an accumulation of extracellular matrix, and no specific medical therapy is approved for that until now. Due to liver metabolic capacity for drugs, the fragility of drugs, and the presence of insurmountable physiological obstacles in the way of targeting, the development of efficient drug delivery systems for anti-fibrotics seems vital. We have explored articles with a different perspective on liver fibrosis over the two decades, then collected and summarized the information by providing corresponding in vitro and in vivo cases. We have discussed the mechanism of hepatic fibrogenesis with different ways of fibrosis induction in animals. Furthermore, the critical chemical and herbal anti-fibrotics, biological molecules such as micro-RNAs, siRNAs, and growth factors, which can affect cell division and differentiation, are mentioned. Likewise, drug and gene delivery and therapeutic systems on in vitro and in vivo models are summarized in the data tables. This review article enlightens recent advances in emerging drugs and nanocarriers and represents perspectives on targeting strategies employed in liver fibrosis treatment.

Abstract
High mobility group box-1 (HMGB1) plays an important role in various liver injuries. In the case of acute liver injury, it leads to aseptic inflammation and other reactions, and also regulates specific cell death responses in chronic liver injury. HMGB1 has been demonstrated to be a good therapeutic target for treating liver failure. Quercetin (Que), as an antioxidant, is a potential phytochemical with hepatocyte protection and is also considered to be an inhibitor of HMGB1. However, the mechanism of its hepatoprotective effects remains to be characterized. The present study explored whether the hepatoprotective effect of Que antagonizes HMGB1, and subsequent molecular signaling events. Our results indicated that Que protects L02 cells from d-galactosamine (d-GaLN)-induced cellular damage by reducing intracellular reactive oxygen species (ROS) production and apoptotic responses in the mitochondrial pathway. Immunofluorescence and Western blot assays showed that HMGB1 was involved in d-GaLN-induced L02 cell damage. Further research showed that after transfection with HMGB1 short hairpin RNA (shRNA), cell viability was improved, and intracellular ROS production and apoptosis were suppressed. When co-treated with Que, the expression of HMGB1 was decreased significantly, the expression of proteins in the corresponding signal pathway were further reduced, and the production of ROS and apoptosis were further suppressed. Molecular docking also indicated the binding of Que and HMGB1. Taken together, these results indicate that Que significantly improves d-GaLN-induced cellular damage by inhibiting oxidative stress and mitochondrial apoptosis via inhibiting HMGB1.

Abstract
This study is aimed to investigate whether calpain 2 (CAPN2) serves as an indicator of the hepatitis B virus (HBV) to induce hepatic fibrosis. Differentially-expressed genes (DEGs) in HBV-induced hepatic fibrosis and normal liver tissues were analyzed, and signal pathway which was analyzed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis using DEGs. Next, the gene-related network map was constructed using the Search Tool for the Retrieval of Interacting Genes. Moreover, CAPN2 protein expression, level of hepatic fibrosis, CAPN2 messenger RNA level, and protein levels of CAPN2, a-SAM, COL3A1, COL1A1, and MAPK1 were determined using Immunohistochemistry (IHC), hematoxylin and eosin, RT-qPCR, and western blot (WB), respectively. There were 420 DEGs screened in HBV-induced hepatic fibrosis and normal liver tissues, among which, 373 were significantly upregulated and 47 were obviously downregulated. KEGG analysis showed that the upregulated DEGs were mainly concentrated in extracellular matrix-receptor interaction, protein digestion, and absorption signaling pathways. The network diagram analysis showed that the DEGs, such as CAPN2, ITGAV, and CCR2, play the key role in the DEG network map, and CAPN2 related to hepatic fibrosis via MAPK1. The increased CAPN2 expression and obvious hepatic fibrosis was displayed in the HBV-induced hepatic fibrosis tissues. In addition, HBV could induce CAPN2 expression, and the interference of CAPN2 could inhibit the expression of hepatic fibrosis markers, including a-SAM, COL3A1, COL1A1, and MAPK1. CAPN2 is regarded as a biomarker of hepatic fibrosis induced by HBV.

Abstract
Liver fibrosis is the common pathological basis of all chronic liver diseases, and is the necessary stage for the progression of chronic liver disease to cirrhosis. As one of pathogenic factors, inflammation plays a predominant role in liver fibrosis via communication and interaction between inflammatory cells, cytokines, and the related signaling pathways. Damaged hepatocytes induce an increase in pro-inflammatory factors, thereby inducing the development of inflammation. In addition, it has been reported that inflammatory response related signaling pathway is the main signal transduction pathway for the development of liver fibrosis. The crosstalk regulatory network leads to hepatic stellate cell activation and proinflammatory cytokine production, which in turn initiate the fibrotic response. Compared with the past, the research on the pathogenesis of liver fibrosis has been greatly developed. However, the liver fibrosis mechanism is complex and many pathways involved need to be further studied. This review mainly focuses on the crosstalk regulatory network among inflammatory cells, cytokines, and the related signaling pathways in the pathogenesis of chronic inflammatory liver diseases. Moreover, we also summarize the recent studies on the mechanisms underlying liver fibrosis and clinical efforts on the targeted therapies against the fibrotic response.

Abstract
The proliferation, migration and differentiation capacities of human periodontal ligament fibroblasts (HPDLCs) are important for the treatment of periodontal diseases. The aim of the present study was to investigate whether icariin could promote these abilities in HPDLCs, and explore the cellular mechanisms therein. The results indicated that icarrin markedly blocked apoptosis, and increased the viability and migration of HPDLCs, particularly at the concentrations of 20 and 50 µM. In addition, icariin significantly promoted HPDLCs to synthesize extracellular matrix, which was reflected by the decreased expression of matrix matalloproteinase-1 and increased expression of tissue inhibitor of metalloproteinase-1. Furthermore, the levels of bone morphogenetic protein 2, collagen I, osteoprotegerin and alkaline phosphatase were markedly elevated by icariin, indicating that icariin was able to promote the osteogenic differentiation capability of HPDLCs. Icariin also inactivated the Toll-like receptor 4 (TLR)-4/nuclear factor (NF)-κB signaling pathway by suppressing the expression levels of TLR-4 and phosphorylated p65, and by blocking p65 nuclear translocation. These results suggested that icarrin increased the survival, migration and osteoblastic differentiation of HPDLCs by inhibiting the TLR-4/NF-κB signaling pathway.

Abstract
The gold nanosensors based on the Au-S bond have been widely applied to biochemical detections. However, signal distortion caused by biothiols has been seldom mentioned and urgently needs to be solved. Herein, we designed a novel but easily assembled gold nanoprobe by coupling a selenol-modified peptide with FITC onto the gold nanoparticle's surface via an Au-Se bond for fluorescence imaging of a tumor marker matrix, metalloproteinases 2 (MMP-2). Compared to the Au-S probes, the Au-Se probes display high thermal stability and a very good anti-interference ability toward glutathione under simulated physiological conditions. More importantly, the Au-Se nanoprobe exhibits a high-fidelity fluorescent signal toward MMP-2, effectively avoiding interference caused by high levels of thiol compounds in vivo. In addition, in vivo experiments further proved that no significant signal intensity change for the tumor cells treated by the Au-Se probes was observed before and after eliminating glutathione. Hence, we believe such Au-Se probes with in vivo glutathione interfering resistance offer new routes and perspectives in biology and medicine in the future.

Abstract
Therapeutic interventions for liver fibrosis are still limited due to the complicated molecular pathogenesis. Renin-angiotensin system (RAS) seems to contribute to the development of hepatic fibrosis. Therefore, we aimed to examine the effect of RAS inhibition on CCl4-induced liver fibrosis. Mice were treated with silymarin (30 mg·kg-1), perindopril (1 mg·kg-1), fosinopril (2 mg·kg-1), or losartan (10 mg·kg-1). The administration of RAS inhibitors improved liver histology and decreased protein expression of alpha smooth muscle actin (α-SMA) and hepatic content of hydroxyproline. These effects found to be mediated via inactivation of nuclear transcription factor kappa B (NFκB) pathway by the inhibition of NFκB p65 phosphorylation at the Ser536 residue and phosphorylation-induced degradation of nuclear factor kappa-B inhibitor alpha (NFκBia) subsequently inhibited NFκB-induced TNF-α and TGF-β1, leading to lower levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) and vascular endothelial growth factor (VEGF). We concluded that the tissue affinity of the angiotensin converting enzyme inhibitors (ACEIs) has no impact on its antifibrotic activity and that interfering the RAS either through the inhibition of ACE or the blockade of AT1R has the same therapeutic benefit. These results suggest RAS inhibitors as promising candidates for further clinical trials in the management of hepatic fibrosis.

Ethyl pyruvate ameliorates hepatic injury following blunt chest trauma and hemorrhagic shock by reducing local inflammation, NF-kappaB activation and HMGB1 release. PLoS One 2018; 13:e0192171. [PMID: 29420582 PMCID: PMC5805235 DOI: 10.1371/journal.pone.0192171] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2017] [Accepted: 01/17/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The treatment of patients with multiple trauma including blunt chest/thoracic trauma (TxT) and hemorrhagic shock (H) is still challenging. Numerous studies show detrimental consequences of TxT and HS resulting in strong inflammatory changes, organ injury and mortality. Additionally, the reperfusion (R) phase plays a key role in triggering inflammation and worsening outcome. Ethyl pyruvate (EP), a stable lipophilic ester, has anti-inflammatory properties. Here, the influence of EP on the inflammatory reaction and liver injury in a double hit model of TxT and H/R in rats was explored. METHODS Female Lewis rats were subjected to TxT followed by hemorrhage/H (60 min, 35±3 mm Hg) and resuscitation/R (TxT+H/R). Reperfusion was performed by either Ringer`s lactated solution (RL) alone or RL supplemented with EP (50 mg/kg). Sham animals underwent all surgical procedures without TxT+H/R. After 2h, blood and liver tissue were collected for analyses, and survival was assessed after 24h. RESULTS Resuscitation with EP significantly improved haemoglobin levels and base excess recovery compared with controls after TxT+H/R, respectively (p<0.05). TxT+H/R-induced significant increase in alanine aminotransferase levels and liver injury were attenuated by EP compared with controls (p<0.05). Local inflammation as shown by increased gene expression of IL-6 and ICAM-1, enhanced ICAM-1 and HMGB1 protein expression and infiltration of the liver with neutrophils were also significantly attenuated by EP compared with controls after TxT+H/R (p<0.05). EP significantly reduced TxT+H/R-induced p65 activation in liver tissue. Survival rates improved by EP from 50% to 70% after TxT+H/R. CONCLUSIONS These data support the concept that the pronounced local pro-inflammatory response in the liver after blunt chest trauma and hemorrhagic shock is associated with NF-κB. In particular, the beneficial anti-inflammatory effects of ethyl pyruvate seem to be regulated by the HMGB1/NF-κB axis in the liver, thereby, restraining inflammatory responses and liver injury after double hit trauma in the rat.
