AbstractIron release from macrophages is closely regulated by the interaction of hepcidin, a peptide hormone produced by hepatocytes, with the macrophage iron exporter ferroportin (FPN1). However, the functions of FPN1 in hepatocyte secretion and macrophage polarization remain unknown. CD68 immunohistochemical staining and double immunofluorescence staining for F4/80 and Ki67 in transgenic mouse livers showed that the number of macrophages in FPN1−/+ and FPN1−/− mouse livers was significantly increased compared to that in WT (FPN+/+) mice. FPN1 downregulation in hepatic cells increased the levels of the M2 markers CD206, TGF- β, VEGF, MMP-9, Laminin, Collagen, IL-4 and IL-10. Furthermore, the expression of CD16/32 and iNOS, as M1 markers, exhibited the opposite trend. Meanwhile, α-SMA immunohistochemistry and Sirius red staining showed that the trend of liver fibrosis in FPN1−/− mice was more significant than that in control mice. Similarly, in vitro FPN1 knockdown in L02-Sh/L02-SCR liver cell lines yielded similar results. Taken together, we demonstrated that downregulated FPN1 expression in hepatocytes can promote the proliferation and polarization of macrophages, leading to hepatic fibrosis. Above all, the FPN1 axis might provide a potential target for hepatic fibrosis.

AbstractHepatic fibrosis is a foreshadowing of future adverse events like liver cirrhosis, liver failure, and cancer. Hepatic stellate cell activation is the main event of liver fibrosis, which results in excessive extracellular matrix deposition and hepatic parenchyma's disintegration. Several biochemical and molecular assays have been introduced for in vitro study of the hepatic fibrosis progression. However, they do not forecast real-time events happening to the in vitro models. Trans-epithelial electrical resistance (TEER) is used in cell culture science to measure cell monolayer barrier integrity. Herein, we explored TEER measurement's utility for monitoring fibrosis development in a dynamic cell culture microphysiological system. Immortal HepG2 cells and fibroblasts were co-cultured, and transforming growth factor β1 (TGF-β1) was used as a fibrosis stimulus to create a liver fibrosis-on-chip model. A glass chip-based embedded TEER and reactive oxygen species (ROS) sensors were employed to gauge the effect of TGF-β1 within the microphysiological system, which promotes a positive feedback response in fibrosis development. Furthermore, albumin, Urea, CYP450 measurements, and immunofluorescent microscopy were performed to correlate the following data with embedded sensors responses. We found that chip embedded electrochemical sensors could be used as a potential substitute for conventional end-point assays for studying fibrosis in microphysiological systems.

Background/Aims: Sestrin 2 is associated with the pathophysiology of several diseases. The aim of this study was to investigate the effects and potential mechanisms of Sestrin 2 in rat hepatic stellate cells (HSCs) during liver fibrogenesis. Methods: In this study, Sestrin 2 protein expression was detected in rat HSC-T6 cells challenged with transforming growth factor-β (TGF-β) and in mice treated with carbon tetrachloride (CCl4), a well-known model of hepatic fibrosis. Next, HSC-T6 cells and fibrotic mice were transfected with lentivirus. The mRNA expression levels of markers of liver fibrosis [alpha-smooth muscle actin (α-SMA) and collagen 1A1 (Col1A1)] were analyzed by quantitative reverse transcription–polymerase chain reaction (RT-PCR). Cell death and proliferation were evaluated by the MTT assay, and biochemical markers of liver damage in serum [alanine transaminase (ALT) and aspartate transaminase (AST)] were also measured using a biochemical analyzer. Histopathological examination was used to evaluate the degree of liver fibrosis, and protein expression [phospho-adenosine monophosphate-activated protein kinase (p-AMPK), AMPK, phospho-mammalian target of rapamycin (p-mTOR), and mTOR] was determined by western blotting. Results: We found that Sestrin 2 was elevated in both the HSC-T6 cell and hepatic fibrosis models. In vitro, overexpression of Sestrin 2 attenuated the mRNA levels of α-SMA and Col1A1, suppressed α-SMA protein expression, and modulated HSC-T6 cell proliferation. In vivo, overexpression of Sestrin 2 reduced the ALT and AST levels as well as the α-SMA and Col1A1 protein expression in the CCl4 model of liver fibrosis. Moreover, the degree of liver fibrosis was ameliorated. Interestingly, overexpression of Sestrin 2 increased p-AMPK but decreased p-mTOR protein expression. Conclusion: Our findings indicate that Sestrin 2 may attenuate the activation of HSCs and ameliorate liver fibrosis, most likely via upregulation of AMPK phosphorylation and suppression of the mTOR signaling pathway.

Abstract Hepcidin, a 25-amino acid peptide hormone which is primarily synthesized and secreted from the liver, is a key regulator of iron homeostasis. It regulates dietary iron absorption, plasma iron concentrations, and tissue iron distribution through interactions with ferroportin, the only known mammalian cellular iron exporter. Hepcidin induces the internalization and subsequent degradation of ferroportin. The reduction in iron release caused by the loss of ferroportin, combined with the continuing demand for iron by erythropoietic precursors, results in a decrease in circulating iron levels. Dysregulation of the hepcidin-ferroportin axis contributes to the pathogenesis of different anemias. Decreased synthesis of hepcidin may cause systemic iron overload in iron-loading anemias such as beta-thalassemia; whereas overproduction of hepcidin may contribute to the development of anemia in inflammatory disorders, malignancies, and chronic kidney disease. LY2928057 is a novel humanized IgG4 monoclonal antibody that binds to human ferroportin with a high affinity, blocks the binding of human hepcidin to ferroportin, and is a potent inhibitor of hepcidin activity in a recombinant ferroportin expressing HEK 293 cell-based assay. In addition, this antibody was able to significantly inhibit hepcidin-induced increase in ferritin levels using Caco-2 cells, a human enterocyte cell line that naturally expresses ferroportin. LY2928057 does not block the efflux of iron from ferroportin, nor does this antibody cause the internalization of this transporter in vitro. Administration of LY2928057 results in a dose dependent increase in serum iron and hepcidin in normal cynomolgus monkeys. LY2928057 may provide therapeutic benefit for patients with hepcidin-related anemia by stabilizing ferroportin located on the cell surface, thus restoring iron export and erythropoiesis. LY2928057 is currently in clinical evaluation. Disclosures: Witcher: Eli Lilly and Company: Employment, Equity Ownership. Leung:Eli Lilly and Company: Employment, Equity Ownership.

Background/Aims: Raf kinase inhibitory protein (RKIP) is closely associated with numerous tumors and participates in their development through regulating the growth, apoptosis, invasion and metastasis of tumor cells. However, the role of RKIP in chronic liver injury and particularly in liver fibrosis is still unclear. Methods: In the present study, hepatic fibrosis was induced by porcine serum (PS) in rats and primary hepatic stellate cells (HSCs) were isolated from rat livers. Moreover, locostatin was used to interfere with RKIP expression. Results: RKIP expression was significantly inhibited by locostatin in both liver tissues of rats and primary HSCs. Down-regulating RKIP expression resulted in serious liver injury, extensive accumulation of collagen, and significant increase in the levels of ALT, AST and TNF-α during liver fibrosis in rats. Moreover, down-regulating RKIP significantly promoted HSCs proliferation and colony formation in vitro. Reduced RKIP significantly increased the production of collagen and the level of α-SMA as well as the expression of MMP-1 and MMP-2 in both liver tissues and primary HSCs. Furthermore, down-regulating RKIP promoted the activation of the ERK and TLR4 signaling pathways. Conclusion: Our findings clearly indicate an inverse correlation between RKIP level and the degree of the liver injury and fibrosis. The decrease in RKIP expression may exacerbate chronic liver injury and liver fibrosis.

Liver fibrosis is characterized by activated hepatic stellate cells (HSC) and extracellular matrix accumulation. Blocking the activation of HSC and the inflammation response are two major effective therapeutic strategies for liver fibrosis. In addition to the long history of using andrographolide (Andro) for inflammatory disorders, we aimed at elucidating the pharmacological effects and potential mechanism of Andro on liver fibrosis. In this study, liver fibrosis was induced by carbon tetrachloride (CCl4) and the mice were intraperitoneally injected with Andro for 6 weeks. HSC cell line (LX-2) and primary HSC were also treated with Andro in vitro. Treatment of CCl4-induced mice with Andro decreased the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), Sirius red staining as well as the expression of α smooth muscle actin (α-SMA) and transforming growth factor- (TGF-) β1. Furthermore, the expression of Toll-like receptor (TLR)4 and NF-κB p50 was also inhibited by Andro. Additionally, in vitro data confirmed that Andro treatment not only attenuated the expression of profibrotic and proinflammatory factors but also blocked the TGF-β1/Smad2 and TLR4/NF-κB p50 pathways. These results demonstrate that Andro prevents liver inflammation and fibrosis, which is in correlation with the inhibition of the TGF-β1/Smad2 and TLR4/NF-κB p50 pathways, highlighting Andro as a potential therapeutic strategy for liver fibrosis.

Chronic liver injury may result in hepatic fibrosis, which can progress to cirrhosis and eventually liver failure. There are no drugs that are specifically approved for treating hepatic fibrosis. The natural product honokiol (HNK), a bioactive compound extracted from Magnolia grandiflora, represents a potential tool in the management of hepatic fibrosis. Though HNK has been reported to exhibit suppressive effects in a rat fibrosis model, the mechanisms accounting for this suppression remain unclear. In the present study, the anti-fibrotic effects of HNK on the liver were evaluated in vivo and in vitro. In vivo studies utilized a murine liver fibrosis model, in which fibrosis is induced by treatment with carbon tetrachloride (CCl4). For in vitro studies, LX-2 human hepatic stellate cells (HSCs) were treated with HNK, and expression of markers of fibrosis, cell viability, the transforming growth factor-β (TGF-β1)/SMAD signaling pathway, and autophagy were analyzed. HNK was well tolerated and significantly attenuated CCl4-induced liver fibrosis in vivo. Moreover, HNK decreased HSC activation and collagen expression by downregulating the TGF-β1/SMAD signaling pathway and autophagy. These results suggest that HNK is a new potential candidate for the treatment of hepatic fibrosis through suppressing both TGF-β1/SMAD signaling and autophagy in HSCs.

Background: Hepatic fibrosis is the result of chronic liver injury that can progress to cirrhosis and lead to liver failure. Nevertheless, there are no anti-fibrotic drugs licensed for human use. Here, we investigated the anti-fibrotic activity of GNS561, a new lysosomotropic molecule with high liver tropism. Methods: The anti-fibrotic effect of GNS561 was determined in vitro using LX-2 hepatic stellate cells (HSCs) and primary human HSCs by studying cell viability, activity of caspases 3/7, autophagic flux, cathepsin maturation and activity, HSC activation and transforming growth factor-β1 (TGF-β1) maturation and signaling. The contribution of GNS561 lysosomotropism to its anti-fibrotic activity was assessed by increasing lysosomal pH. The potency of GNS561 on fibrosis was evaluated in vivo in a rat model of diethylnitrosamine-induced liver fibrosis. Results: GNS561 significantly decreased cell viability and promoted apoptosis. Disrupting the lysosomal pH gradient impaired its pharmacological effects, suggesting that GNS561 lysosomotropism mediated cell death. GNS561 impaired cathepsin activity, leading to defective TGF-β1 maturation and autophagic processes. Moreover, GNS561 decreased HSC activation and extracellular matrix deposition by downregulating TGF-β1/Smad and mitogen-activated proteine kinase signaling and inducing fibrolysis. Finally, oral administration of GNS561 (15 mg/kg per day) was well tolerated and attenuated diethylnitrosamine-induced liver fibrosis in this rat model (decrease of collagen deposition and of pro-fibrotic markers and increase of fibrolysis). Conclusion: GNS561 is a new potent lysosomotropic compound that could represent a valid medicinal option for hepatic fibrosis treatment through both its anti-fibrotic and its pro-fibrolytic effects. In addition, this study provides a rationale for targeting lysosomes as a promising therapeutic strategy in liver fibrosis.

Inhibition or blockade of HSCs (hepatic stellate cells), the main matrix-producing cells involved in the wound-healing response, represents an attractive strategy for the treatment of liver fibrosis. In vitro studies have shown that activation of AMPK (AMP-activated protein kinase), a key player in the regulation of cellular energy homoeostasis, inhibits proliferation of myofibroblasts derived from HSCs. If AMPK is a true regulator of fibrogenesis then defective AMPK activity would enhance fibrogenesis and hepatic fibrosis. To test this, in the present work, in vitro studies were performed on mouse primary HSCs treated or not with the AMPK activator AICAR (5-amino-4-imidazolecarboxamide ribonucleotide) or isolated from mice lacking the AMPKα1 catalytic subunit (AMPKα1−/−) or their littermates (AMPKα1+/+). Liver fibrosis was induced in vivo in AMPKα1−/− and AMPKα1+/+ mice by repeated injections of CCl4 (carbon tetrachloride). During culture activation of HSCs, AMPK protein and activity significantly increased and regulatory AMPKγ3 mRNA was specifically up-regulated. Stimulation of AMPK activity by AICAR inhibited HSC proliferation, as expected, as well as collagen α1(I) expression. Importantly, AMPKα1 deletion inhibited proliferation of HSCs, but not fibrogenesis, in vivo. Moreover, AMPKα1 deletion was not associated with enhanced CCl4-induced fibrosis in vivo. In conclusion, our present findings demonstrate that HSC transdifferentiation is associated with increased AMPK activity that could relate to the stabilization of AMPK complex by the γ3 subunits. Activation of AMPK in HSCs inhibits in vitro fibrogenesis. By contrast, low AMPK activity does not prevent HSC activation in vitro nor in in vivo fibrosis.

AbstractBackground & AimsAspirin has potent anti-platelet activities and possibly helps regression of fibrosis. We investigated antifibrotic mechanisms of aspirin in the murine CCl4 model and in patients with hepatic fibrosis.MethodsMultiomics analysis identified networks and molecular targets regulated by aspirin which were validated in murine model and in patients with liver fibrosis.ResultsBiochemical/histopathological changes and hepatic fibrosis were greater in CCl4-treated mice compared to CCl4-aspirin (CCl4+ASA) or control mice (p<0.05). In CCl4+ASA mice, integrated proteome-metabolome analysis showed an increase in autophagy, drug metabolism, glutathione and energy metabolism (p<0.05) and decrease in inflammatory pathways, arachidonic acid and butanoate metabolism (p<0.05). Global cross-correlation analysis linked fibrosis markers with protein-metabolite pathways (r2>0.5, p<0.05). Liver proteome enrichment for immune clusters using blood transcription module correlated with histidine and tryptophan metabolism (r2>0.5, p<0.05). Aspirin decreased Ryanodine-receptor-2 (RYR2;oxidative-stress), Arginase-1 (ARG-1;urea cycle), Arachidonate-5-lipoxygenase (ALOX5;leukotriene metabolism), and Kynurenine-3-monooxygenase (KMO;tryptophan metabolism; p<0.05) which correlated with reduction in α-SMA, PDGFR-β and degree of hepatic fibrosis (r2>0.75; p<0.05) in animal and human studies, and, in-vitro analysis. Aspirin modulated intracellular-calcium and oxidative-stress levels by reducing RYR2 expression in activated LX-2 cells. It modulated the liver microbiome and its functions which also correlated with ARG1, ALOX5, RYR2 expression (r2>0.5, p<0.05). Metaproteome analysis showed significant microbiome similarity at phylum level in murine liver tissues and fecal samples. Aspirin increased the abundance of Firmicutes (Ruminococcaceae, Lachnospiraceae, and Clostridiaceae) and their functionality, as assessed by glycerol-3-phosphate dehydrogenase (NAD(P)(+) and dTMP-kinase activity (p<0.05).ConclusionsAspirin demonstrates broad beneficial effects following oxidative injury, inflammation, and hepatic fibrosis. Aspirin induces distinctive hepatic proteome/metabolome and intrahepatic microbiome changes which are indicative of fibrosis regression and could be further explored as therapeutic targets.
