Biomed Pharmacother 2023; 168:115777. [PMID: 37913732 DOI: 10.1016/j.biopha.2023.115777] [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: 07/23/2023] [Revised: 10/12/2023] [Accepted: 10/20/2023] [Indexed: 11/03/2023] Open
Abstract
End-stage of liver fibrosis as a precancerous state could lead to cirrhosis and hepatocellular carcinoma which liver transplantation is the only effective treatment. Previous studies have indicated that farnesoid X receptor (FXR) agonists, such as obeticholic acid (OCA) protect against hepatic injuries. However, free OCA administration results in side effects in clinical trials that could be alleviated by applying bio carriers such as MSC-derived exosomes (Exo) with the potential to mimic the biological regenerative effect of their parent cells, as proposed in this study. Loading OCA into the Exo was conducted via water bath sonication. Ex vivo bio distribution studies validated the Exo-loaded OCA more permanently accumulated in the liver. Using CCL4-induced liver fibrosis, we proposed whether Exo isolated from human Warton's Jelly mesenchymal stem cells loaded with a minimal dosage of OCA can facilitate liver recovery. Notably, Exo-loaded OCA exerted additive anti-fibrotic efficacy on histopathological features in CCL4-induced fibrotic mice. Compared to baseline, Exo-mediated delivery OCA results in marked improvements in the fibrotic-related indicators as well as serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations. Accordingly, the synergistic impact of Exo-loaded OCA as a promising approach is associated with the inactivation of hepatic stellate cells (HSCs), extracellular matrix (ECM) remodeling, and Fxr-Cyp7a1 cascade on CCL4-induced liver fibrosis mice. In conclusion, our data confirmed the additive protective effects of Exo-loaded OCA in fibrotic mice, which suggests a valuable therapeutic strategy to combat liver fibrosis. Furthermore, the use of Exo for accurate drug delivery to the liver tissue can be inspiring.

Biomed Pharmacother 2023; 161:114472.

Abstract
Liver fibrosis is the common consequence of various chronic liver injuries and is mainly characterized by the imbalance between the production and degradation of extracellular matrix, which leads to the accumulation of interstitial collagen and other matrix components. Matrix metalloproteinases (MMPs) and their specific inhibitors, that is, tissue inhibitors of metalloproteinases (TIMPs), play a crucial role in collagen synthesis and lysis. Previous in vivo and in vitro studies of our laboratory found repressing extracellular matrix (ECM) accumulation by restoring the balance between MMPs and TIMPs can alleviate liver fibrosis. We conducted a review of articles published in PubMed and Science Direct in the last decade until February 1, 2023, which were searched for using these words "MMPs/TIMPs" and "Hepatic Fibrosis." Through a literature review, this article reviews the experimental studies of liver fibrosis based on MMPs/TIMPs, summarizes the components that may exert an anti-liver fibrosis effect by affecting the expression or activity of MMPs/TIMPs, and attempts to clarify the mechanism of MMPs/TIMPs in regulating collagen homeostasis, so as to provide support for the development of anti-liver fibrosis drugs. We found the MMP-TIMP-ECM interaction can result in better understanding of the pathogenesis and progression of hepatic fibrosis from a different angle, and targeting this interaction may be a promising therapeutic strategy for hepatic fibrosis. Additionally, we summarized and analyzed the drugs that have been found to reduce liver fibrosis by changing the ratio of MMPs/TIMPs, including medicine natural products.

Abstract
Fibroblasts activation is a crucial process for development of fibrosis during idiopathic pulmonary fibrosis pathogenesis, and transforming growth factor (TGF)-β1 plays a key regulatory role in fibroblast activation. It has been reported that metformin (MET) alleviated bleomycin (BLM)-induced pulmonary fibrosis (PF) by regulating TGF-β1-induced fibroblasts activation, but the underlying mechanisms still deserve further investigations. In this study, MET blocked α-smooth muscle actin (α-SMA) accumulation in vivo accompanied with S100A4 expression and STAT3 phosphorylation inhibition, resulting in attenuating the progression of lung fibrosis after BLM administration. We determined that S100A4 plays critical roles in fibroblasts activation in vitro, evidenced by siRNA knockdown of S100A4 expression downregulated TGF-β1 induced α-SMA production in Human fetal lung fibroblast (HFL1) cells. Importantly, we found for the first time that the expression of S100A4 in fibroblasts was regulated by STAT3. Stattic, an effective small molecule inhibitor of STAT3 phosphorylation, reduced S100A4 level in TGF-β1- treated HFL1 cells accompanied with less α-SMA production. We further found that MET, which inhibits STAT3 phosphorylation by AMPK activation, also inhibits fibroblasts activation by targeting S100A4 in vitro. Together all these results, we conclude that S100A4 contributes to TGF-β1- induced pro-fibrogenic function in fibroblasts activation, and MET was able to protect against TGF-β1-induced fibroblasts activation and BLM-induced PF by down-regulating S100A4 expression through AMPK-STAT3 axis. These results provide a useful clue for a clinical strategy to prevent PF.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent and slow progressing hepatic pathology characterized by different stages of increasing severity which can ultimately give rise to the development of hepatocellular carcinoma (HCC). Besides drastic lifestyle changes, few drugs are effective to some extent alleviate NAFLD and HCC remains a poorly curable cancer. Among the deregulated molecular mechanisms promoting NAFLD and HCC, several members of the S100 proteins family appear to play an important role in the development of hepatic steatosis, non-alcoholic steatohepatitis (NASH) and HCC. Specific members of this Ca2+-binding protein family are indeed significantly overexpressed in either parenchymal or non-parenchymal liver cells, where they exert pleiotropic pathological functions driving NAFLD/NASH to severe stages and/or cancer development. The aberrant activity of S100 specific isoforms has also been reported to drive malignancy in liver cancers. Herein, we discuss the implication of several key members of this family, e.g., S100A4, S100A6, S100A8, S100A9 and S100A11, in NAFLD and HCC, with a particular focus on their intracellular versus extracellular functions in different hepatic cell types. Their clinical relevance as non-invasive diagnostic/prognostic biomarkers for the different stages of NAFLD and HCC, or their pharmacological targeting for therapeutic purpose, is further debated.

Abstract
The aim of the present study was to investigate the expression and prognostic value of microRNA-135a (miR-135a) and matrix metalloproteinase-13 (MMP-13) in serum of colon cancer (CC). A total of 117 cases of patients admitted to Sheng Li Oil Field Central Hospital from May 2015 to May 2017 were enrolled in the research group (RG), and 120 cases of subjects undergoing normal health examination were included in the control group (CG). The expression of miR-135 and MMP-13 in peripheral blood of the two groups were compared, and their values were analyzed. It was found that miR-135a was decreased and MMP-13 was increased in the RG (P<0.050), both of which were closely related to the pathological features and prognosis of CC (P<0.050), and was also significantly correlated with CEA (P<0.001). ROC curve analysis showed that both of them had great predictive value for the occurrence, prognosis and death of CC. In conclusion, miR-135a was low expressed in CC, while MMP-13 was increased in CC, suggesting that the combined detection of the two had a good diagnostic effect on the occurrence of CC, and was closely related to the prognosis of CCC patients, which might be an excellent potential indicator for the diagnosis and treatment of CC in the future.

Abstract
The aim of this study was elucidate the inhibitory role of growth differentiation factor 15 (GDF15) in liver fibrosis and its possible activation mechanism in hepatic stellate cells (HSCs) of mice. We generated a GDF15-neutralizing antibody that can inhibit TGF-β1-induced activation of the TGF-β/Smad2/3 pathway in LX-2 cells. All the mice in this study were induced by carbon tetrachloride and thioacetamide. In addition, primary HSCs from mice were isolated from fresh livers using Nycodenz density gradient separation. The severity and extent of liver fibrosis were evaluated by Sirius Red and Masson staining. The effect of GDF15 on the activation of the TGF-β pathway was detected using dual-luciferase reporter and Western blotting assays. The expression of GDF15 in cirrhotic liver tissue was higher than that in normal liver tissue. Blocking GDF15 with a neutralizing antibody resulted in a delay in primary hepatic stellate cell activation and remission of liver fibrosis induced by carbon tetrachloride or thioacetamide. Meanwhile, TGF-β pathway activation was partly inhibited by a GDF15-neutralizing antibody in primary HSCs. These results indicated that GDF15 plays an important role in regulating HSC activation and liver fibrosis progression. The inhibition of GDF15 attenuates chemical-inducible liver fibrosis and delays hepatic stellate cell activation, and this effect is probably mainly attributed to its regulatory role in TGF-β signalling.

Abstract
RATIONALE Nonalcoholic fatty liver disease (NAFLD), the most common cause of chronic liver disease, has become an increasingly severe public health problem. However, the underlying mechanism for the occurrence and development of NAFLD remains largely unknown. S100 calcium-binding protein A11 (S100A11) is a multifunctional protein previously reported to be a poor prognostic indicator of hepatocellular carcinoma, while the role of S100A11 affects NAFLD is still not clear. METHODS Immunohistochemical staining was performed using human NAFLD and control biopsy specimens. Serum level of S100A11 were analyzed by Elisa assays. The S100A11 over-expressed/ knocked-down model was established in vitro or in vivo. The expression levels of genes related to lipid metabolism in liver tissue were performed by quantitative PCR and western blotting. Hepatic lipid accumulation was determined by biochemical measurements and histochemistry. RESULTS We showed that the concentration of serum S100A11 was significantly elevated in NAFLD patients, and expression of S100A11 was remarkedly increased in the livers of NAFLD patients and mouse models. Overexpression of S100A11 in vivo markedly increased liver steatosis, body weight, and serum aspartate aminotransaminase (AST) levels. Mechanistically, our results demonstrated that S100A11 acted as a positive regulator of AKT/mTOR signaling to induce lipid synthesis and aggravate lipid deposition. CONCLUSIONS These results provide evidence for a novel role of S100A11 that contributes to hepatic steatosis, suggesting that targeting S100A11 may be an alternative approach for the treatment of NAFLD.

Abstract
Adhesions are fibrotic scars that form between abdominal organs following surgery or infection, and may cause bowel obstruction, chronic pain, or infertility. Our understanding of adhesion biology is limited, which explains the paucity of anti-adhesion treatments. Here we present a systematic analysis of mouse and human adhesion tissues. First, we show that adhesions derive primarily from the visceral peritoneum, consistent with our clinical experience that adhesions form primarily following laparotomy rather than laparoscopy. Second, adhesions are formed by poly-clonal proliferating tissue-resident fibroblasts. Third, using single cell RNA-sequencing, we identify heterogeneity among adhesion fibroblasts, which is more pronounced at early timepoints. Fourth, JUN promotes adhesion formation and results in upregulation of PDGFRA expression. With JUN suppression, adhesion formation is diminished. Our findings support JUN as a therapeutic target to prevent adhesions. An anti-JUN therapy that could be applied intra-operatively to prevent adhesion formation could dramatically improve the lives of surgical patients.

Abstract
Spontaneous mutations in the SHANK-associated RH domain interacting protein (Sharpin) resulted in a severe autoinflammatory type of chronic proliferative dermatitis, inflammation in other organs, and lymphoid organ defects. To determine whether cell-type restricted loss of Sharpin causes similar lesions, a conditional null mutant was created. Ubiquitously expressing cre-recombinase recapitulated the phenotype seen in spontaneous mutant mice. Limiting expression to keratinocytes (using a Krt14-cre) induced a chronic eosinophilic dermatitis, but no inflammation in other organs or lymphoid organ defects. The dermatitis was associated with a markedly increased concentration of serum IgE and IL18. Crosses with S100a4-cre resulted in milder skin lesions and moderate to severe arthritis. This conditional null mutant will enable more detailed studies on the role of SHARPIN in regulating NFkB and inflammation, while the Krt14-Sharpin-/- provides a new model to study atopic dermatitis.

Abstract
Previous circular RNA (circRNA) microarray analyses have uncovered an abnormal expression of hsa_circ_0070963 in hepatic stellate cells (HSCs). However, the specific role of hsa_circ_0070963 in liver fibrosis remains unknown. Here, we show that hsa_circ_0070963 inhibits liver fibrosis via regulation of miR-223-3p and LEMD3. Moreover, we demonstrated that hsa_circ_0070963 levels were reduced during liver fibrosis while restoring hsa_circ_0070963 levels abolished HSC activation, with a reduction in α-SMA and type I collagen levels both in vitro and in vivo. Furthermore, hsa_circ_0070963 overexpression suppressed both cell proliferation and the cell cycle of HSCs. MiR-223-3p was confirmed as a target of hsa_circ_0070963 and was shown to be involved in the effects of hsa_circ_0070963 on HSC activation. Furthermore, LEMD3 was confirmed as a target of miR-223-3p and was shown to be responsible for the activation of HSCs. The interactions between hsa_circ_0070963, miR-223-3p, and LEMD3 were validated via bioinformatic analysis, luciferase reporter assays, and rescue experiments. Collectively, hsa_circ_0070963 appeared to function as a miR-223-3p sponge that inhibited HSC activation in liver fibrosis via regulation of miR-223-3p and LEMD3. Therefore, hsa_circ_0070963 may serve as a potential therapeutic target for liver fibrosis.

Abstract
Recent researches have indicated that S100A4 participates in tissue fibrosis, whereas calcimycin inhibits this process as a novel S100A4 transcription inhibitor. However, the relationship and mechanisms between calcimycin and S100A4 in keloid fibroblasts (KFs) remain unknown. The present research was aimed to evaluate the effect of calcimycin on S100A4 expression and pathogenesis in KFs. Keloid fibroblasts were cultured and exposed to different concentrations of calcimycin in the absence or presence of transforming growth factor β1 (TGF-β1). The results showed that the expression of S100A4 was significantly increased in keloid derived fibroblasts compared with normal skin fibroblasts. Calcimycin depressed S100A4 in a concentration- and time-dependent manner. Moreover, calcimycin suppressed TGF-β1-induced collagen type I, fibronectin, and α-smooth muscle actin expression and cell viability in cultured KFs. Furthermore, calcimycin modulated expression of TGF-β/Smad target genes Smad7 and phosphorylation of TGF-β1-induced Smad2/3. This research for the first time confirmed the presence of S100A4 in KFs. Calcimycin inhibits the expression of S100A4, as well as KF proliferation and migration and extracellular matrix (ECM) synthesis. Taken together, these results indicate that calcimycin might be a therapeutic candidate to keloid or other related fibrotic disorders.

Locostatin Alleviates Liver Fibrosis Induced by Carbon Tetrachloride in Mice. Dig Dis Sci 2019; 64:2570-2580. [PMID: 30874989 DOI: 10.1007/s10620-019-05588-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Accepted: 03/08/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND AND AIMS Liver fibrosis is featured with excessive deposition of extracellular matrix and fibrous connective tissue hyperplasia. The specific inhibitor of Raf-1 kinase inhibitor protein, locostatin, inhibits the migration of hepatic stellate cells. In this study, we investigated the effect of locostatin on liver fibrosis and its underlying mechanism. METHODS Carbon tetrachloride (CCl4) was used to induce liver fibrosis in mice, and locostatin was injected intraperitoneally. Liver fibrosis was assessed by Masson and Sirius red staining, hydroxyproline (HYP) assay, and collagen percentage area. Collagen I, collagen III, and α-SMA were detected by RT-PCR and western blot. The levels of MMP-13, MMP-2, TIMP-1, and TIMP-2 were estimated by ELISA. Liver inflammation was evaluated by HE staining and immunohistochemistry; liver myeloperoxidase (MPO), superoxide dismutase, and malondialdehyde were measured by ELISA; and cytokines were by Mouse Cytokine Array Q4000. RESULTS Compared to the CCl4 group, HYP (208.56 ± 6.12) µg/g, percentage of total collagen at overall region (1.91 ± 0.13), MMP-13/TIMP-1 (0.19 ± 0.01), MPO (1.45 ± 0.04) U/g, TGF-β (2652 ± 91.20), PDGF-AA (3897 ± 290.69), and E-selectin (1569 ± 66.48) in the liver tissues were decreased significantly in the locostatin-treated group. CONCLUSIONS Locostatin mitigated liver fibrosis and inflammation induced by CCl4. The mechanism is via inhibition inflammatory cytokines, TGF-β, PDGF-AA, and E-selectin.

Abstract
Identification of pro-regenerative approaches to improve tendon healing is critically important as the fibrotic healing response impairs physical function. In the present study we tested the hypothesis that S100a4 haploinsufficiency or inhibition of S100a4 signaling improves tendon function following acute injury and surgical repair in a murine model. We demonstrate that S100a4 drives fibrotic tendon healing primarily through a cell non-autonomous process, with S100a4 haploinsufficiency promoting regenerative tendon healing. Moreover, inhibition of S100a4 signaling via antagonism of its putative receptor, RAGE, also decreases scar formation. Mechanistically, S100a4 haploinsufficiency decreases myofibroblast and macrophage content at the site of injury, with both cell populations being key drivers of fibrotic progression. Moreover, S100a4-lineage cells become α-SMA+ myofibroblasts, via loss of S100a4 expression. Using a combination of genetic mouse models, small molecule inhibitors and in vitro studies we have defined S100a4 as a novel, promising therapeutic candidate to improve tendon function after acute injury.

Stem Cell Res Ther 2019; 10:16. [PMID: 30635047 PMCID: PMC6329168 DOI: 10.1186/s13287-018-1122-8] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 12/11/2018] [Accepted: 12/25/2018] [Indexed: 12/31/2022] Open
Abstract
Background Liver fibrosis is a key phase that will progress to further injuries such as liver cirrhosis or carcinoma. This study aimed to investigate whether transplantation of bone marrow mesenchymal stromal cells (BM-MSCs) can attenuate liver fibrosis in mice and the underlying mechanisms based on the regulation of macrophage subtypes. Methods A liver fibrosis model was induced by intraperitoneal (i.p.) injection of CCl4 twice per week for 70 days, and BM-MSCs were intravenously transplanted twice on the 60th and 70th days. Immunohistology and gene expression of liver fibrosis and macrophage subtypes were analyzed. Mouse RAW264.7 cells and JS1 cells (hepatic stellate cell strain) were also used to explore the underlying mechanisms of the effects of BM-MSCs on liver fibrosis. Results After transplantation of BM-MSCs, F4/80+CD206+-activated M2 macrophages and matrix metalloproteinase 13 (MMP 13) expression were significantly increased while F4/80+iNOS+-activated M1 macrophages were inhibited in liver tissue. Gene expression of IL-10 was elevated while IL12b, IFN-γ, TNF-α, and IL-6 gene expression were decreased. ΤGF-β1 and collagen-1 secretions were reduced while caspase-3 was increased in JS1 cells treated with BM-MSC-conditioned media. BM-MSCs effectively suppressed the expression of α-SMA, Sirius red, and collagen-1 in the liver, which are positively correlated with fibrosis and induced by CCl4 injection. Conclusions Taken together, we have provided the first demonstration that BM-MSC transplantation can promote the activation of M2 macrophages expressing MMP13 and inhibition of M1 macrophages to further inhibit hepatic stellate cells (HSCs), which play synergistic roles in attenuating liver fibrosis.

Yonsei Med J 2018; 59:1064-1071. [PMID: 30328321 PMCID: PMC6192886 DOI: 10.3349/ymj.2018.59.9.1064] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Revised: 08/06/2018] [Accepted: 08/24/2018] [Indexed: 12/17/2022] Open
Abstract
PURPOSE To explore the influence of S100 calcium binding protein A4 (S100A4) knockout (KO) on methionine-choline-deficient (MCD) diet-induced non-alcoholic fatty liver disease (NAFLD) in mice. MATERIALS AND METHODS S100A4 KO mice (n=20) and their wild-type (WT) counterparts (n=20) were randomly divided into KO/MCD, Ko/methionine-choline-sufficient (MCS), WT/MCD, and WT/MCS groups. After 8 weeks of feeding, blood lipid and liver function-related indexes were measured. HE, Oil Red O, and Masson stainings were used to observe the changes of liver histopathology. Additionally, expressions of S100A4 and proinflammatory and profibrogenic cytokines were detected by qRT-PCR and Western blot, while hepatocyte apoptosis was revealed by TUNEL staining. RESULTS Serum levels of aminotransferase, aspartate aminotransferase, triglyceride, and total cholesterol in mice were increased after 8-week MCD feeding, and hepatocytes performed varying balloon-like changes with increased inflammatory cell infiltration and collagen fibers; however, these effects were improved in mice of KO/MCD group. Meanwhile, total NAFLD activity scores and fibrosis were lower compared to WT+MCD group. Compared to WT/MCS group, S100A4 expression in liver tissue of WT/MCD group was enhanced. The expression of proinflammatory (TNF-α, IL-1β, IL-6) and profibrogenic cytokines (TGF-β1, COL1A1, α-SMA) in MCD-induced NAFLD mice were increased, as well as apoptotic index (AI). For MCD group, the expressions of proinflammatory and profibrogenic cytokines and AI in KO mice were lower than those of WT mice. CONCLUSION S100A4 was detected to be upregulated in NAFLD, while S100A4 KO alleviated liver fibrosis and inflammation, in addition to inhibiting hepatocyte apoptosis.

Front Immunol 2018; 9:1572.

Abstract
Our previous investigations indicated that in vitro polarization of mouse macrophages by Toxoplasma gondii type II strain dense granule protein 15 (GRA15 II ), one of the genotype-associated effectors of T. gondii, induced the phenotypes of classically activated macrophage (M1). Transfusion of the cells to mice may effectively alleviated hepatic fibrosis caused by schistosomiasis. The purpose of the study was to identify whether liver macrophages can be in vivo driven to M1 macrophages by lentiviral vector (LV) carrying GRA15 II gene (LV-gra15 II ) and to explore the potential mechanism by which the LV-gra15 II -activated liver macrophage (LV-gra15 II -M) ameliorates the hepatic fibrosis in schistosomiasis. The mice were treated with LV-gra15 II by hydrodynamic injection via the tail vein followed by challenge of Schistosoma japonicum (S. japonicum). Our experiments showed that LV-gra15 II was successfully delivered to liver macrophages and GRA15II was persistently expressed in the macrophages of mice for at least 2 months. Furthermore, the LV-gra15 II infected macrophages were polarized to M1 macrophages in vivo. Consequently, mice with schistosomiasis receiving LV-gra15 II injection displayed a remarkable amelioration of liver granuloma formation and collagen deposition in association with downregulated expression of transforming growth factor-beta1, arginase 1 (Arg-1), α-smooth muscle actin, and an increased expression of matrix metalloproteinase 13 (MMP13). Simultaneously, no negative effects of liver function and vitality of mice were noted. The in vitro experiments indicated that the C-C motif chemokine ligand 2 and nitric oxide level were elevated in LV-gra15 II -M cultural supernatants; hepatocyte growth factor expression was enhanced in LV-gra15 II -M. In addition, LV-gra15 II -M not only secreted MMP13, which greatly degraded type I collagen, but also induced murine hepatic stellate cell (HSC) line (JS1) apoptosis in the co-culture system. Taken together, we identified for the first time that LV-gra15 II may in vivo drive liver macrophages to M1 macrophage phenotypes, which helps for alteration of the liver fibrotic microenvironment with collagen dissolution, HSC deactivation, apoptosis and hepatocyte protection. Our study gives an insight into the use of gene delivery with parasite-derived immunomodulatory factor as a potential immune cell activating agent to re-equilibrate the other pathogen-induced immune response in some chronic diseases.

Clin Res Hepatol Gastroenterol 2018; 42:64-71.

Abstract
AIM The diagnostic performance of Fibroscan might be improved when combined with other serum fibrosis related markers. Previous study has demonstrated that S100A4 expression is associated with liver fibrosis in humans with hepatitis. This study aimed to clarify diagnostic accuracy of serum S100A4 levels for significant liver fibrosis in patients with chronic hepatitis B (CHB), and develop a combined algorithm of liver stiffness measurement (LSM) and S100A4 to predict significant liver fibrosis in CHB. METHODS One hundred and seventy-five CHB patients who had performed liver biopsy were consecutively included. We evaluated serum S100A4 levels, LSM values and other clinically-approved fibrosis scores. RESULTS Serum S100A4 level was higher in CHB patients with significant fibrosis, compared to those without [199.58 (33.31-1971.96) vs. 107.15 (2.10-1038.94), P<0.001]. Using receiver-operating characteristic (ROC) analyses, the area under the curves (AUC), sensitivity, specificity and accuracy of S100A4 were found to be 0.749, 62.7%, 75.9% and 0.70 for significant fibrosis (≥Stage 2), respectively. Although not superior to LSM, these results were better than the fibrosis index based on the 4 factor (FIB-4) and the aspartate aminotransferase-to-platelet ratio index (APRI) for significant fibrosis detection. An algorithm consisting of S100A4 and LSM was derived. The AUC, sensitivity, specificity and accuracy of model based on serum S100A4 level and LSM were 0.866, 86.6%, 77.8% and 0.79 for significant fibrosis detection, superior to those based on LSM alone (0.834, 76.1%, 80.7% and 0.76, P=0.041). CONCLUSION Serum S100A4 level was identified as a fibrosis marker of liver fibrosis in patients with CHB. Combining serum S100A4 with LSM improved the accuracy of transient elastography for hepatitis B significant fibrosis detection.

Depletion of S100A4 + stromal cells does not prevent HCC development but reduces the stem cell-like phenotype of the tumors. Exp Mol Med 2018; 50:e422.

Abstract
There is a pressing need for the development of novel approaches to treat and prevent hepatocellular carcinoma (HCC). The S100 calcium-binding protein S100A4 is associated with poor prognosis and metastasis in several human cancers. In addition, a role for S100A4 in modulating cancer-initiating cells stemness properties was recently proposed in head and neck and gastric cancers. Whether S100A4+ stromal cells contribute to tumor onset remains, however, an unanswered question. To address that question, we generated a new mouse model allowing for the depletion of S100A4+ cells in a mouse model of HCC with stemness properties, by crossing mice with hepatic deletion of phosphatase and tensin homolog (PTEN) with mice expressing viral thymidine kinase under the control of S100A4 promoter. Depletion of S100A4+ cells by ganciclovir injection did not prevent the development of HCC but reduced the stemness phenotype of the tumor as measured by the expression of progenitor cell, biliary cell and hepatocyte markers. The results were further confirmed by histology analysis showing reduction of cholangiolar tumor components and degree of oval cell hyperplasia in the adjacent liver. Depletion of S100A4+ cells had also some beneficial effect on the underlying liver disease with a reduction of NAS score, largely due to the reduction of inflammation. In conclusion, this study demonstrated that S100A4+ cells do not contribute to HCC onset but maintain the stemness phenotype of the tumor. This study also suggests for the first time a crosstalk between inflammation and stemness.

Abstract
The present study aimed to investigate the hepatoprotective role of Licochalcone E (LCE) and its mechanism of action in a mouse model of carbon tetrachloride (CCl4)-induced liver toxicity. Hepatotoxicity was induced in Kunming mice via an intraperitoneal injection (IP) of CCl4, 10 ml/kg body weight, diluted with corn oil at a 1:500 ratio. LCE was administered once a day for 7 days (IP) as pretreatment at a dose of 5 mg/kg/day. The levels of C-reactive protein (CRP) and tumor necrosis factor (TNF)-α were analyzed to determine the inflammation status. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed using ELISA assays. Liver ultrastructure was observed via optical microscopy. The mRNA and protein expression levels of peroxisome proliferator-activated receptor (PPAR)γ, and nuclear factor (NF)-κB were assayed using quantitative polymerase chain reaction and western blot analysis, respectively. Pretreatment with LCE decreased levels of ALT, AST, CRP and TNF-α, and NF-κB expression in the experimental hepatotoxicity mice model induced by CCl4. In addition, LCE increased the expression of PPARγ and normalized the hepatic histoarchitecture. However, the effects of LCE were reversed by cotreatment with the PPARγ inhibitor GW9662. The present study suggests that LCE may be used for the treatment of hepatotoxicity, and primarily exhibits its protective role through a PPARγ/NF-κB-mediated pathway.

Abstract
Tendon injuries heal via scar tissue rather than regeneration. This healing response forms adhesions between the flexor tendons in the hand and surrounding tissues, resulting in impaired range of motion and hand function. Mechanistically, inflammation has been strongly linked to adhesion formation, and Prostaglandin E2 (PGE2) is associated with both adhesion formation and tendinopathy. In the present study we tested the hypothesis that deletion of the PGE2 receptor EP4 in S100a4-lineage cells would decrease adhesion formation. S100a4-Cre; EP4 flox/flox (EP4cKOS100a4) repairs healed with improved gliding function at day 14, followed by impaired gliding at day 28, relative to wild type. Interestingly, EP4cKOS100a4 resulted in only transient deletion of EP4, suggesting up-regulation of EP4 in an alternative cell population in these mice. Loss of EP4 in Scleraxis-lineage cells did not alter gliding function, suggesting that Scx-lineage cells are not the predominant EP4 expressing population. In contrast, a dramatic increase in α-SMA+, EP4+ double-positive cells were observed in EP4cKOS100a4 suggesting that EP4cKOS100a4 repairs heal with increased infiltration of EP4 expressing α-SMA myofibroblasts, identifying a potential mechanism of late up-regulation of EP4 and impaired gliding function in EP4cKOS100a4 tendon repairs.

Microarray profiling of circular RNAs and the potential regulatory role of hsa_circ_0071410 in the activated human hepatic stellate cell induced by irradiation. Gene 2017; 629:35-42.

Abstract
Radiation-induced liver fibrosis (RILF) is considered as a major complication of radiation therapy for liver cancer. Circular RNA (circRNA) has been recently identified as a functional noncoding RNA involving in various biological processes. However, the expression pattern and regulatory capacity of circRNA in the irradiated hepatic stellate cell (HSC), the main fibrogenic cell type, still remain unclear. A circRNA microarray was used to identify circRNA expression profiles in irradiated and normal HSC. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to confirm the dysregulated circRNAs. Bioinformatic analyses including gene ontology (GO), KEGG pathway and circRNA/microRNA interaction network analysis were applied to predict the potential functions of circRNAs. Compared with the normal HSC, 179 circRNAs were found to be up-regulated and 630 circRNAs were down-regulated in irradiated HSC (fold change ≥2.0 and P<0.05). Six dysregulated circRNAs selected randomly were successfully verified by qRT-PCR. Bioinformatic analyses indicated that dysregulated circRNA might be involved in the cell response to irradiation and biological processes of hepatic fibrosis. Furthermore, inhibition of hsa_circ_0071410 increased the expression of miR-9-5p, resulting in the attenuation of irradiation induced HSC activation. In summary, this study revealed the expression profile and potential function of differentially expressed circRNAs in irradiated HSC, which provides novel clues for RILF study.

[PMID: 28143589 PMCID: PMC5286822 DOI: 10.1186/s13104-017-2409-z] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2016] [Accepted: 01/25/2017] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The Curcuma longa L. (CLL) rhizome has long been used to treat patients with hepatic dysfunction. CLL is a member of the ginger family of spices that are widely used in China, India, and Japan, and is a common spice, coloring, flavoring, and traditional medicine. This study was performed to evaluate the hepatoprotective activity of CLL extract and its active component curcumin in an acute carbon tetrachloride (CCl4)-induced liver stress model. METHODS Acute hepatic stress was induced by a single intraperitoneal injection of CCl4 (0.1 ml/kg body weight) in rats. CLL extract was administered once a day for 3 days at three dose levels (100, 200, and 300 mg/kg/day) and curcumin was administered once a day at the 200 mg/kg/day. We performed alanine transaminase (ALT) and aspartate transaminase (AST). activity analysis and also measured total lipid, triglyceride, and cholesterol levels, and lipid peroxidation. RESULTS At 100 g CLL, the curcuminoid components curcumin (901.63 ± 5.37 mg/100 g), bis-demethoxycurcumin (108.28 ± 2.89 mg/100 g), and demethoxycurcumin (234.85 ± 1.85 mg/100 g) were quantified through high liquid chromatography analysis. In CCl4-treated rats, serum AST and ALT levels increased 2.1- and 1.2-fold compared with the control. AST but not ALT elevation induced by CCl4 was significantly alleviated in CLL- and curcumin-treated rats. Peroxidation of membrane lipids in the liver was significantly prevented by CLL (100, 200, and 300 mg/kg/day) on tissue lipid peroxidation assay and immunostaining with anti-4HNE antibody. We found that CLL extract and curcumin exhibited significant protection against liver injury by improving hepatic superoxide dismutase (p < 0.05) and glutathione peroxidase activity, and glutathione content in the CCl4-treated group (p < 0.05), leading to a reduced lipid peroxidase level. CONCLUSION Our data suggested that CLL extract and curcumin protect the liver from acute CCl4-induced injury in a rodent model by suppressing hepatic oxidative stress. Therefore, CLL extract and curcumin are potential therapeutic antioxidant agents against acute hepatotoxicity.

Abstract
INTRODUCTION The aim of our study was to assess association of serum S100A4 protein with ulcerative colitis (UC) and Crohn's disease (CD). METHODS Study included 118 subjects: 93 patients with CD, 16 with UC and 9 controls. In CD group, 20/93 patients had B1 phenotype, 19/93 B2, 20/93 B3 and 34/93 B2 + B3. L1 involvement was present in 15/93, L2 in 14/93 and L3 in 64/93 patients. Serum S100A4 concentration was investigated in peripheral venous blood samples by means of ELISA. RESULTS Serum S100A4 was significantly higher in UC (158.6 ± 56.2 ng/mL), p = 0.019 and in CD (154.4 ± 52.1 ng/mL), p = 0.007 compared to controls (104.8 ± 40.5 ng/mL). No difference in S100A4 was revealed between UC and CD, p > 0.05. Serum S100A4 in each CD subgroup (according to behaviour) was significantly higher compared to controls, p < 0.05. Serum S100A4 was significantly higher in L2 (144.6 ± 44.2 ng/mL), p = 0.041 and in L3 (163.0 ± 52.8 ng/mL), p = 0.002 compared to controls and in L3 compared to L1 (126.9 ± 47.6 ng/mL), p = 0.017. CONCLUSION Association of serum S100A4 protein with UC and CD was confirmed. In CD, disease behaviour did not influence serum concentration of S100A4 protein. In CD, higher levels of serum S100A4 were observed in patients with ileo-colonic and colonic involvement compared to those with isolated small bowel involvement.
