Abstract
Liver fibrosis is a pathological condition characterized by replacement of normal liver tissue with scar tissue, and also the leading cause of liver-related death worldwide. During the treatment of liver fibrosis, in addition to antiviral therapy or removal of inducers, there remains a lack of specific and effective treatment strategies. For thousands of years, Chinese herbal medicines (CHMs) have been widely used to treat liver fibrosis in clinical setting. CHMs are effective for liver fibrosis, though its mechanisms of action are unclear. In recent years, many studies have attempted to determine the possible mechanisms of action of CHMs in treating liver fibrosis. There have been substantial improvements in the experimental investigation of CHMs which have greatly promoted the understanding of anti-liver fibrosis mechanisms. In this review, the role of CHMs in the treatment of liver fibrosis is described, based on studies over the past decade, which has addressed the various mechanisms and signaling pathways that mediate therapeutic efficacy. Among them, inhibition of stellate cell activation is identified as the most common mechanism. This article provides insights into the research direction of CHMs, in order to expand its clinical application range and improve its effectiveness.

Du J, Liu L, Fan H, Yu Y, Luo Y, Gu F, Yu H, Liao X. Anthocyanins improve liver fibrosis in mice by regulating the autophagic flux level of hepatic stellate cells by mmu_circ_0000623. Food Sci Nutr 2023; 11:3002-3018. [PMID: 37324880 PMCID: PMC10261807 DOI: 10.1002/fsn3.3281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/03/2023] [Accepted: 02/14/2023] [Indexed: 06/17/2023] Open
Abstract
Liver fibrosis is a key step in the progression of various chronic liver diseases to liver cirrhosis and even liver cancer, it is also an important link affecting prognosis. Therefore, this study aimed to investigate the therapeutic effect of anthocyanins on liver fibrosis and the molecular mechanism of mmu_circ_0000623 in anthocyanin therapy. In this study, CCL4 was used to build a mouse liver fibrosis model, and the treatment groups were treated with 100 and 200 mg/kg of anthocyanins daily by gavage. Liver fibrosis indicators, macrophage polarization markers, and liver injury markers were further detected by real-time quantitative PCR (qRT-PCR), western blotting (WB), and enzyme-linked immunosorbent assay. Morphological verification of liver injury in different treatment groups was performed by histopathological method. A mouse hepatic stellate cell (HSC) model and a mouse liver fibrosis model were constructed to verify the expression of circ_0000623, miR-351-5p, and TFEB. Transfected with mRFP-GFP-LC3 to detect the autophagic flux of HSCs. We found that 100 mg/kg or 200 mg/kg of anthocyanins could significantly reduce the degree of liver fibrosis in mice. In addition, anthocyanins can inhibit the proliferation, activation, and migration ability of HSCs. circ_0000623 was lowly expressed in mice with liver fibrosis, and anthocyanin treatment could promote its increased expression. Further testing found that anthocyanins could reverse the blocked autophagic flux induced by PDGF or CCL4. This effect is achieved by regulating the expression of TFEB by competitive adsorption of miR-351-5p. Anthocyanins could treat liver fibrosis by modulating circ_0000623/miR-351-5p/TFEB-mediated changes in HSC autophagic flux.

Calotropis gigantea stem bark extracts inhibit liver cancer induced by diethylnitrosamine. Sci Rep 2022; 12:12151. [PMID: 35840761 PMCID: PMC9287404 DOI: 10.1038/s41598-022-16321-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Accepted: 07/08/2022] [Indexed: 11/09/2022] Open
Abstract
Several fractions of Calotropis gigantea extracts have been proposed to have potential anticancer activity in many cancer models. The present study evaluated the anticancer activity of C. gigantea stem bark extracts in liver cancer HepG2 cells and diethylnitrosamine (DEN)-induced primary liver cancer in rats. The carcinogenesis model induced by DEN administration has been widely used to study pathophysiological features and responses in rats that are comparable to those seen in cancer patients. The dichloromethane (CGDCM), ethyl acetate, and water fractions obtained from partitioning crude ethanolic extract were quantitatively analyzed for several groups of secondary metabolites and calactin contents. A combination of C. gigantea stem bark extracts with doxorubicin (DOX) was assessed in this study to demonstrate the enhanced cytotoxic effect to cancer compared to the single administration. The combination of DOX and CGDCM, which had the most potential cytotoxic effect in HepG2 cells when compared to the other three fractions, significantly increased cytotoxicity through the apoptotic effect with increased caspase-3 expression. This combination treatment also reduced ATP levels, implying a correlation between ATP and apoptosis induction. In a rat model of DEN-induced liver cancer, treatment with DOX, C. gigantea at low (CGDCM-L) and high (CGDCM-H) doses, and DOX + CGDCM-H for 4 weeks decreased the progression of liver cancer by lowering the liver weight/body weight ratio and the occurrence of liver hyperplastic nodules, fibrosis, and proliferative cells. The therapeutic applications lowered TNF-α, IL-6, TGF-β, and α-SMA inflammatory cytokines in a similar way, implying that CGDCM had a curative effect against the inflammation-induced liver carcinogenesis produced by DEN exposure. Furthermore, CGDCM and DOX therapy decreased ATP and fatty acid synthesis in rat liver cancer, which was correlated with apoptosis inhibition. CGDCM reduced cleaved caspase-3 expression in liver cancer rats when used alone or in combination with DOX, implying that apoptosis-inducing hepatic carcinogenesis was suppressed. Our results also verified the low toxicity of CGDCM injection on the internal organs of rats. Thus, this research clearly demonstrated a promising, novel anticancer approach that could be applied in future clinical studies of CGDCM and combination therapy.

Abstract
The importance of the "gut-liver axis" in the pathogenesis of liver diseases has been revealed recently; which promotes the process of developing preventive and therapeutic strategies. However, considering that there are still many challenges in the medical treatment of liver diseases, potential preventive dietary intervention may be a good alternative choice. Plant-based foods have received much attention due to their reported health-promoting effects in targeting multiple pathways involved in the pathogenesis of liver diseases as well as the relative safety for general use. Based on the PubMed and Web of Science databases, this review emphatically summarizes the plant-based foods and their chemical constituents with reported effects to impact the LPS/TLR4 signaling pathway of gut-liver axis of various liver diseases, reflecting their health benefits in preventing/alleviating liver diseases. Moreover, some plant-based foods with potential gut-liver effects are specifically analyzed from the reported studies and conclusions. This review intends to provide readers an overview of the current progress in the field of this research topic. We expect to see more hepatoprotective measures for alleviating the current prevalence of liver diseases.

Abstract
The knowledge of RNA editing modifications and its subsequent proteomic diversity in is still limited and represents only the tip of the iceberg. Adenosine to inosine (A-to-I) RNA editing is the most prevalent in RNA editome with a rising role for ADARgene family as a major regulator of the dynamic landscape of RNA editing. This study aimed at evaluating the potential chemopreventive effects of the epigenetic regulator "pterostilbene" in diethylnitrosamine (DEN)-exposedrat model. Consequently, the hepatic Adars expression was investigated as a possible mechanism for mediation of the putative pterostilbene-induced chemopreventive effect. The effects of administration of pterostilbene were investigated on the structural changes, immunohistochemical staining, liver function test, serum alpha feto-protein (AFP), IL-6, and hepatic Adar1 and Adar2 relative gene expression at the beginning and at the 6th week of the study. Pterostilbene attenuated DEN-induced liver injury, improves hepatocyte parrafin-1 (Hep Par-1), decreases heat shock protein 70 (HSP70), improved AFP, serum albumin, transaminases, IL-6 with alleviation of disturbed hepatic Adar1 and Adar2 expression. This study spotlights the role of pterostilbene in attenuation of DEN-induced liver injury which could be mediated, at least partially, through the alleviation of the aberrant expression of Adar enzymes. Yet, more in-depth studies are needed to further elucidate the molecular mechanisms underlying the effects of pterostilbene on RNA editing enzymes.

Abstract
ETHNOBOTANICAL RELEVANCE Tectona grandis L.f (or syn: Jatus grandis (L.f.) Kuntze Revis), from family Lamiaceae, also known as Teak, is widely recognized in ayurvedic system of medicine and confer curative potential against inflammation, liver disorders, biliousness, diabetes, bronchitis, leprosy and dysentery. Its leaves are rich source of edible food colorant and reported nontoxic for liver and various organs. AIM OF STUDY Hepatic injury progression to liver cirrhosis and cancer is a serious health issue across the world. Currently, anti-fibrotic therapeutic options are limited and expensive with no FDA approved direct anti-hepato-fibrotic drug validated in clinic. Thus, the aim of this study was to understand ameliorative effect of Tectona grandis L.f, leaves in early liver fibrosis. METHOD AND RESULTS C57BL/6 mice suffering from CCl4 induced liver injury, were orally administered at three different doses (50, 100 & 200 mg/kg) of Tectona grandis L.f, leaf extract, thrice a week, up to 4 and 8 weeks. Anti-fibrotic effect was evaluated through animal body/liver weight measurements, serological tests (AST, ALT, GSH, MDA and LDH assays), tissue hydroxyproline content, and histochemical analysis (H&E, Masson trichrome, Sirius red and αSMA localization). Moreover, transcriptional and post-transcriptional expression of fibrosis associated biomarkers and TGF-β/Smad cascade were analyzed. It was observed that 100 mg/kg dose optimally downregulated TGF-β1/Smad2 with upregulation of Smad7 and regulated αSMA, Col 1, PDGF, TIMP1 and MMP3 expression, post 8 weeks of treatment. In addition, MMP3/TIMP1 ratio was upregulated to 0.7, 2.5 and 1.7 fold at 50 mg/kg, 100 mg/kg & 200 mg/kg treatments respectively, in comparison to untreated liver fibrosis models. The extract contains gallic acid, caffeic acid, sinapinic acid and myricetin when analyzed through high performance liquid chromatography. CONCLUSION Tectona grandis L.f, leaves have potential to ameliorate liver fibrosis induced by CCl4 in mice via modulation of TGF-β1/Smad pathway and upregulated MMP3/TIMP1 ratio.

Abstract
BACKGROUND Blueberries are polyphenol-rich fruits with antioxidant and anti-inflammatory properties. Polyphenols from berries act by blocking digestive enzymes, reshaping gastrointestinal microbiota, and affecting the release of gastrointestinal hormones to regulate insulin dynamics and glucose management. However, most studies use fruit extracts instead of fresh fruit. We aimed to evaluate postprandial glucose management and antioxidant capacity of fresh blueberries consumed acutely or as a six-day supplementation in 10 sedentary subjects. METHODS To evaluate the effect of acute blueberry intake, 150 g of blueberries were consumed together with 150 g of white bread by the subject and blood samples were collected at 0, 30, 60, 90 and 120 min to measure glucose, insulin, and plasma antioxidant capacity. To evaluate supplementation, 150 g of blueberries were provided daily for six days and sample collection was performed at day 7. RESULTS Acute consumption of blueberries decreased postprandial glucose area under the curve (AUC) and increased insulin levels at 15 min timepoint. Supplementation did not affect glucose levels but decreased insulin levels at 120 min. No changes in antioxidant capacity were observed. CONCLUSIONS Consumption of fresh blueberries improves postprandial glucose management presumably due to actions on the gastrointestinal tract, while supplementation improves insulin sensitivity, probably due antioxidant and anti-inflammatory effects.

Abstract
The application of chemicals in industry and agriculture has contributed to environmental pollution and exposure of living organisms to harmful factors. The development of new pharmaceutical agents enabled successful therapy of various diseases, but their administration may be connected with side effects. Oxidative stress has been found to be involved into etiology of numerous diseases as well as harmful action of drugs and chemicals. For some time, plant origin substances have been studied as potential protective agents alleviating toxicity of various substances and symptoms of diseases. The aim of the current review was to present the diversity of the research performed during the last five years on animal models. The outcomes showed a huge protective potential inherent in plant preparations, including alleviating prooxidative processes, strengthening antioxidant defence, ameliorating immune parameters, and reversing histopathological changes. In many cases, plant origin substances were proved to be comparable or even better than standard drugs. Such findings let us suggest that in the future the plant preparations could make adjuvants or a replacement for pharmaceutical agents. However, the detailed research regarding dose and way of administration as well as the per se effects needs to be performed. In many studies, the last issue was not studied, and in some cases, the deleterious effects have been observed.

Abstract
OBJECTIVES The aim of the present study was to investigate the potential of pterostilbene, a beneficial component primarily found in blueberries, to alleviate the intrauterine growth retardation (IUGR)-induced early liver injury and oxidative stress in a porcine model. METHODS Thirty-six IUGR piglets and an equal number of normal birth weight (NBW) counterparts received a diet with or without pterostilbene (250 mg/kg diet) during the first week post-weaning. Parameters related to the hepatic injury, oxidative stress, and antioxidant defense mechanisms were analyzed. RESULTS Relative to NBW, IUGR induced liver injury, which corresponded to increments in circulating alanine transaminase activity and hepatic apoptotic cell rate, superoxide radical generation, and the accumulation of oxidative damage products (P < 0.05). Administering pterostilbene reduced plasma transaminase activities, decreased hepatocyte apoptosis rate, and prevented the augmented levels of hepatic superoxide anion, 8-hydroxy-2 deoxyguanosine, and 4-hydroxynonenal-modified protein (P < 0.05). In terms of the hepatic antioxidant function, pterostilbene was efficient in improving the superoxide dismutase activity and the metabolic cycle between reduced glutathione and its oxidized form (P < 0.05). The pterostilbene-supplemented diet facilitated the nuclear translocation of nuclear factor erythroid-2-related factor 2 (NRF2) and promoted the expression levels of superoxide dismutase 2 in the liver of IUGR piglets (P < 0.05). CONCLUSION This study indicates that pterostilbene treatment has an auxiliary therapeutic potential to ameliorate early liver injury in IUGR neonates, presumably by stimulating the NRF2 signals and the associated antioxidant function.

Abstract
OBJECTIVE Recently, blueberry has been identified as a candidate for the treatment of liver fibrosis. Given the role of gut-liver axis in liver fibrosis and the importance of the gut microbiota homeostasis to the maintenance of the intestinal epithelial barrier, this study aimed to investigate whether blueberry could attenuate liver fibrosis and protect the intestinal epithelial barrier by maintaining the homeostasis of the gut microbiota. METHOD A CCl4-induced rat liver fibrosis model was used to detect the roles of blueberry in liver fibrosis and intestinal epithelial barrier. The liver weight and body weight were measured, the liver function was monitored by ALT and AST activity, protein and mRNA were determined by western blot and RT-qPCR, and the gut microbiome was detected by Miseq. RESULTS The results showed that blueberry could reduce the rate of liver weight/body weight gain (p < 0.05), ALT (p < 0.01) and AST (p < 0.05) activity, and the expression of collagen I (p < 0.01), collagen IV (p < 0.01), and α-SMA (p < 0.01) expression in CCl4-induced rat liver. CCl4 impaired the intestinal epithelial barrier and decreased the expression of the tight junction protein. Blueberry restored the intestinal epithelial barrier and increased the expression of the tight junction protein. The gut microbiota homeostasis was impaired by CCl4, but after treatment with blueberry, the intestinal flora returned to normal. CONCLUSION Blueberry attenuated liver fibrosis, protected intestinal epithelial barrier, and maintained the homeostasis of the gut microbiota in a CCl4-induced injury rat model.

Abstract
We previously reported that extracts from plants of the Ericaceae genus Vaccinium, commonly known as the kind of blueberry, inhibited the early steps of influenza virus (IFV) infection to host cells, and that the activity was correlated with the total polyphenol content. Particularly potent inhibitory activity was observed for Vaccinium oldhamii. In this study, we identified the active components in Vaccinium oldhamii involved in the inhibition of IFV infection. We sequentially fractionated the Vaccinium oldhamii extract using a synthetic adsorbent resin column. High inhibitory activity was observed for the fractions eluted with 30%, 40%, and 50% ethanol, and three peaks (peak A, B, and C) considered to represent polyphenols were identified in the fractions by HPLC analysis. Among these peaks, high inhibitory activity was detected for peak A and B, but not for peak C. These peaks were analyzed by LC/MS, which revealed that peak A contained procyanidin B2 and ferulic acid derivatives, whereas peak B contained two ferulic acid O-hexosides, and peak C contained quercetin-3-O-rhamnoside and quercetin-O-pentoside-O-rhamnoside. It is already known that these polyphenols have anti-IFV activity, but we speculate that ferulic acid derivatives are the major contributors to the inhibition of the early steps of IFV replication, such as either adsorption or entry, observed for Vaccinium oldhamii.

Abstract
Nearly 40% of men and women will be diagnosed with cancer during their lifetime. Thus, there is a rapidly growing need for novel therapies to combat this deadly disease. One such method is the consumption of blueberries. Long coveted for their powerful antioxidant properties, more recent studies have demonstrated that blueberries also exhibit inherent abilities to prevent carcinogenesis, inhibit the proliferation of neoplastic cells, and reduce the risks of recurrence in patients in remission. This review will focus on the specific activities of blueberry derivatives in cancer cells across many different forms of cancer. Ultimately, such research could be helpful in the development of new strategies to treat cancer.

Abstract
Increasing prevalence of nonalcoholic fatty liver disease (NAFLD) in parallel with the obesity epidemic has been a major public health concern. NAFLD is the most common chronic liver disease in the United States, ranging from fatty liver to steatohepatitis, fibrosis and cirrhosis in the liver. In response to chronic liver injury, fibrogenesis in the liver occurs as a protective response; however, prolonged and dysregulated fibrogenesis can lead to liver fibrosis, which can further progress to cirrhosis and eventually hepatocellular carcinoma. Interplay of hepatocytes, macrophages and hepatic stellate cells (HSCs) in the hepatic inflammatory and oxidative milieu is critical for the development of NAFLD. In particular, HSCs play a major role in the production of extracellular matrix proteins. Studies have demonstrated that bioactive food components and natural products, including astaxanthin, curcumin, blueberry, silymarin, coffee, vitamin C, vitamin E, vitamin D, resveratrol, quercetin and epigallocatechin-3-gallate, have antifibrotic effects in the liver. This review summarizes current knowledge of the mechanistic insight into the antifibrotic actions of the aforementioned bioactive food components.

Nelumbo nucifera leaf extract treatment attenuated preneoplastic lesions and oxidative stress in the livers of diethylnitrosamine-treated rats. ENVIRONMENTAL TOXICOLOGY 2017; 32:2327-2340. [PMID: 28804948 DOI: 10.1002/tox.22434] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2016] [Revised: 04/26/2017] [Accepted: 04/26/2017] [Indexed: 06/07/2023]
Abstract
Lotus (Nelumbo nucifera Gaertn) possesses antioxidant, hepatoprotective, and anticancer potential. This study determined the protective role of aqueous extract from Nelumbo nucifera leaves (NLE) against N-diethylnitrosamine (DEN)-induced oxidative stress and hepatocellular carcinogenesis in a sample of Sprague-Dawley rats. NLE was fed orally to rats in which hepatic carcinoma was induced with DEN for 12 weeks. Five groups of 12 rats each were used for the study: Group I (control group) rats received distilled water; Group II rats were induced with DEN; Group III rats were induced with DEN and cotreated with 0.5% NLE; Group IV rats were induced with DEN and cotreated with 1.0% NLE; and Group V rats were induced with DEN and cotreated with 2.0% NLE. Clinical chemistry, organ weight, inflammatory marker, protein expression, enzyme, and antioxidant analyses were conducted. NLE administration to rats resulted in significantly decreased levels of serum alanine aminotransferase, aspartate aminotransferase, and albumin, which is indicative of hepatocellular damage, compared with the control group. DEN-induced oxidative stress was inhibited by NLE and this inhibition was paralleled by decreased lipid peroxides and increased glutathione transferase, superoxide dismutase, catalase, and glutathione peroxidase activity in liver tissues. The status of nonenzymatic antioxidants, such as reduced glutathione, was also found to be increased in NLE-administered rats. Furthermore, NLE decreased tumor size, hepatic Rac1, PKCα, and GSTπ expressions compared with the DEN-only group. Thus, supplementation of NLE reduced the adverse changes that occur because of liver cancer. These results prove that NLE protects against liver carcinogenesis induced because of treatment with DEN through blocking lipid peroxidation, hepatic cell damage, and enhancing the antioxidant defense system.
