[PMID: 36572326 DOI: 10.1016/j.jep.2022.116069] [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: 09/24/2022] [Revised: 11/22/2022] [Accepted: 12/16/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Herpetospermum pedunculosum seeds is a traditional Tibetan medicine possessing hepatoprotective effect, but their protective effect on APAP-induced liver injury has not yet been explored. AIM OF THE STUDY This study aimed at exploring the protective effect and mechanism of the water extract from the seeds of Herpetospermum pedunculosum (HPWE) on APAP-induced liver injury in vitro and in vivo. MATERIALS AND METHODS In vitro and in vivo models of liver injury were established by APAP treatment of BRL-3A cells or mice. The effect and mechanism of action of HPWE were explored by using cell viability assay, ELISA, immunofluorescence assay, RT-qPCR, histological observation and immunohistochemistry staining, western blotting and high-content imaging system. RESULTS In vitro experiments showed that HPWE treatment significantly promoted the cell viability, decreased ALT/AST level, and inhibited the ROS accumulation induced by APAP. Furthermore, HPWE and Fer-1 alleviated erastin-induced cell ferroptosis, upregulated GPX4 and SLC7A11 expression, and reduced lipid peroxides production. Further study showed that APAP could also downregulate the expression of GPX4 and SLC7A11, causing cell ferroptosis, and HPWE and Fer-1 counteracted this process. Our in vivo experiments showed that pretreatment with HPWE in APAP-treated mice significantly alleviated the serum ALT/AST level, decreased necrotic cells and inflammatory cell infiltration, upregulated the expression of GPX4 and SLC7A11. Further, it was demonstrated that HPWE treatment downregulated Nrf2 and its downstream target genes, i.e. HO-1 and NQO1 expression at the mRNA and protein levels. HPWE treatment also inhibited the activation of NF-κB p65 and downregulated its target genes, i.e. TNF-α and IL-1β, expression. CONCLUSION The present study showed that HPWE could relieve oxidative stress and ferroptosis via activating Nrf2 signaling pathway and inhibiting NF-κB mediated pathway.

Abstract
Background: Cholestasis is described as a disease in which bile flow from the liver is reduced or stopped, and due to its oxidative effects, irreversible consequences may occur. Due to the remarkable antioxidant properties of Oliveria decumbens (OD) and the contribution of oxidants to the progression of bile duct ligation (BDL)-induced cholestasis, Objectives: This research aimed to examine how the OD ethanolic extract affected liver damage and oxidant-antioxidant balance markers in BDL-induced cholestasis. Methods: Forty male Wistar rats weighing 200 - 250 g were used. Cholestasis was induced using the BDL approach. The rats were categorized into four groups: Group 1, sham control (SC); group 2, cholestatic; group 3, SC + OD; and group 4, cholestatic + OD. A dose of OD ethanolic extract was administered orally (500 mg/kg/day) to rats for seven days. Seven days following surgery, the rats’ blood samples were collected; after sacrifice, a part of the liver tissue was isolated. A histopathological examination was performed, while the rest was stored at -70°C in liquid nitrogen. Heparin-containing tubes were used to gather blood samples. In plasma and hepatic tissue, biochemical tests, histopathological evaluations, and oxidative stress markers staining levels were performed. Results: Our findings showed that OD could effectively reduce liver injury by reducing the activity of liver function enzymes (AST and ALP). At the same time, it did not affect total bilirubin and protein. Bile duct ligation-induced hepatic markers of protein oxidation (PCO) and reactive nitrogen species (NO) were significantly decreased by OD, and it also promoted liver antioxidant capacity by enhancing superoxide dismutase (SOD) activities. Moreover, OD treatment prevented liver bile duct proliferative changes in histopathologic analysis. Conclusions: Our study confirmed that OD exerts substantial hepatoprotective activities against BDL-induced cholestasis by improving liver damage markers and regulating oxidative stress. It may be a beneficial therapeutic agent for managing cholestasis. Bioassay-guided isolation and identification of bioactive OD secondary metabolites can further direct the discovery of potential natural-based drug candidates.

Abstract
Abrus mollis Hance is a traditional Chinese medicine that is widely used to treat acute and chronic hepatitis, steatosis, and fibrosis. Its therapeutic qualities of it have long been acknowledged, although the active ingredients responsible for its efficacy and the mechanisms of its action are unknown. In this study, the chemical constituents absorbed into the blood from Abrus mollis Hance were assessed by using liquid chromatography-quadrupole-time-of-flight mass spectrometry and the data was analyzed with the UNIFI screening platform. The results obtained were compared to existing chromatographic-mass spectrometry information, including retention times and molecular weights as well as known reference compounds. 41 chemical constituents were found in Abrus mollis Hance, and these included 16 flavonoids, 13 triterpenoids, five organic acids, and two alkaloids. Experimentally it was found that Abrus mollis Hance had a therapeutic benefit when treating α-naphthalene isothiocyanate-induced acute liver injury in rats. In addition, 11 blood prototypical constituents, including six flavonoids, three triterpenoids, and two alkaloids, were found in serum samples following intragastric administration of Abrus mollis Hance extracts to rats. This novel study can be used for the quality control and pharmacodynamic assessment of Abrus mollis Hance in order to assess its efficacy in the therapeutic treatment of patients.

iTRAQ Quantitative Proteomic Analysis of Different Expressed Proteins and Signal Pathways in Bakuchiol-Induced Hepatotoxicity. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:2928240. [PMID: 36193146 PMCID: PMC9526664 DOI: 10.1155/2022/2928240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Accepted: 07/25/2022] [Indexed: 11/18/2022]
Abstract
Bakuchiol (BAK) is an abundant natural compound. BAK has been reported to have several biological activities such as anticancer, antiaging, anti-inflammatory, and prevention of bone loss. However, it causes hepatotoxicity, the mechanism of which is not known. In this study, we explored the mechanism of BAK hepatotoxicity by treating rats with 52.5 mg/kg and 262.5 mg/kg of BAK, administered continuously for 6 weeks. We examined the liver pathology and biochemical composition of bile to determine toxicity. Mechanisms of BAK hepatotoxicity were analyzed based on relative and absolute quantification (iTRAQ) protein equivalent signatures and validated in vitro using LO2 cells. iTRAQ analysis revealed 281 differentially expressed proteins (DEPs) in liver tissue of the BAK-treated group, of which 215 were upregulated, and 66 were downregulated. GO and KEGG enrichment analysis revealed that bile secretion, lipid metabolism, and cytochrome P450 signaling pathways were enriched in DEPs. Among them, peroxisome proliferator-activated receptor α (PPARα), farnesoid X receptor (FXR), and cholesterol 7α-hydroxylase (CYP7a1) were closely associated with the development and progression of BAK-induced hepatic metabolic dysfunction and abnormal bile metabolism. This study shows that BAK can induce hepatotoxicity through multiple signaling pathways.

Abstract
Cholestasis is a common liver injury without any effective therapeutic drugs so far. Resveratrol (RES) and luteolin (LUT) are natural polyphenols that exert protective effects on multiple liver injuries. Coadministration of RES and LUT could significantly improve the bioavailability of LUT and increase the systemic exposure to RES, and the combined treatment could also benefit from their multi-component and multi-target characteristics. Our current aim is to study the protective effects of coadministration of RES and LUT on α-naphthylisothiocyanate (ANIT)-induced cholestasis. Serum biochemical indices and liver histopathology in rats indicated that coadministration of RES and LUT could improve liver function by suppressing oxidative stress. Dysregulated bile acid (BA) homeostasis is a significant pathological feature of cholestasis, which was determined to explore the potential biomarkers and to clarify the protection mechanism of coadministration of RES and LUT. The levels of cholic acid, chenodeoxycholic acid, taurine conjugates and glycine conjugates, and the ratios of taurine conjugates to their free forms could be used as diagnosis indicators for cholestasis in rats. Furthermore, the coadministration of RES and LUT could restore the BA levels and exert better protective effects than administration alone. This study suggested that the coadministration of RES and LUT could protect against ANIT-induced cholestasis and the mechanism was closely related to regulating BA homeostasis and suppressing oxidative stress.

Abstract
The seeds of Herpetospermum pedunculosum (Ser.) C.B. Clarke, a well-known Tibetan medicine in China, are rich in kinds of bioactive lignans. In this phytochemical investigation on H. pedunculosum, sixteen undescribed lignans, named as herpedulins A - P together with 24 known ones were isolated from the ethyl acetate extract of its seeds. Their structures including the absolute configurations were determined by HR MS, 1D and 2D NMR experiments, and comparison of their experimental ECD spectra with calculated ones or literature data. High content screening experiments revealed that 9 compounds could promote the expression of farnesoid X receptor in guggulsterone-induced human normal liver cells L02 cells significantly. Further molecular docking results demonstrated that herpedulin E, J and K exhibited best docking scores (9.70, 9.28 and 10.31, respectively). Hydrogen bonding and hydrophobic interactions might contribute to the main interaction of active compounds with FXR.

Abstract
Liver injury is the early stage of liver disease, which is caused by multiple factors. Baicalein has shown extensive bioactivity. But whether baicalein has a protective effect on liver injury has not been reported thus far. In this study, we aim to investigate the protective effects of baicalein on liver injury induced by oxidative stress. H2O2 and CCl4 were employed to establish liver injury models in vivo and in vitro, respectively. The protective effect of baicalein on oxidative stress-induced liver injury was evaluated by detecting the mitochondrial dynamics, the level of autophagy and apoptosis, the histopathology of liver, the indicators of liver function, and the level of oxidative stress in vitro and in vivo. March5 is the key regulator during liver injury induced by oxidative stress. March5 can ubiquitinate Drp1 and promote Drp1 degradation, then maintain the homeostasis of mitochondrial dynamics, keep the balance of autophagy, and reduce apoptosis. Baicalein is able to effectively reduce liver injury; it can contribute to the expression of March5 by regulating KLF4 during liver injury. These results indicate that baicalein plays a key role in salvaging liver from injury induced by oxidative stress via regulating the KLF4-March5-Drp1 signal pathway.

Abstract
Introduction Cholestasis is caused by malfunction of the hepatobiliary system. This disorder is the result of the accumulation of bile fatty acids and other toxins in the liver. The aim of the current study was to investigate the antioxidative and hepatoprotective effects of methanolic extract of Origanum majorana L. (OM) on hepatic disorder and tissue damage induced by bile duct ligation (BDL) in rats. Materials and methods. Twenty-eight male Wistar rats were randomly divided into 4 groups including sham control group received vehicle (SC-V), bile duct ligation received vehicle (BDL-V), bile duct ligation group received OM extract (BDL + OM), and sham control group received OM extract (SC + OM). One day after surgery, the animals received vehicle or methanolic extract of OM 300 mg/kg/day for 7 consecutive days by oral gavage. Finally, the animals were anesthetized and the blood samples were collected from each animal. After sacrificing of animals, liver tissue from each rat was removed and divided into three parts: one part was used for preparing of homogenized tissue, one part was fixed in 10% neutral formalin for histopathology examination, and the third part was kept in liquid nitrogen for gene expression analysis. Biomarkers of oxidative stress in the liver tissue and serum, as well as histopathological changes of the liver, were assessed. Also, the gene expression of IL-1, TNF-α, TGF-β, and α-SMA has been measured. Results The results showed that BDL-V significantly increased the activity of ALT, AST, ALP, and total bilirubin compared to the SC-V group. The oxidative stress markers such as MDA and FRAP significantly increased due to BDL, while the CAT activity reduced in the BDL-V group compared to SC-V group. Oral treatment with OM reduced ALT and AST activity, although it was not statistically significant. OM treatment considerably increased the activity of CAT compared to BDL group. BDL-V induced a significant histological change in the liver, while treatment with OM at a dose of 300 mg/kg showed a minor effect on histopathological changes. In addition, the mRNA of IL-1, TNF-α, TGF-β, and α-SMA significantly increased in the BDL-V group, while treatment with OM only significantly reduced TGF-β in comparison with BDL-V rats. Conclusions The results of the present study showed that oral administration of OM extract had a moderate protective effect on cholestasis due to BDL. Indeed, more studies with different doses of extract are needed to confirm this finding.

Abstract
Alcoholic liver diseases (ALDs) impose a substantial health burden on many countries. Bioactive peptides isolated from people, marine organisms, animals and plants have shown hepatoprotective effects on animal and hepatocyte models. In this study, an LO2 cell model of ethanol-induced liver injury in vitro was constructed. We investigated the hepatoprotective effects of the three-spot seahorse bioactive peptide (SBP) PAGPRGPA (Pro-Ala-Gly-Pro-Arg-Gly-Pro-Ala; 721.39 Da) and characterised the underlying metabolic pathways and biomarkers through a nontargeted metabolomics approach. We found that ethanol-induced oxidative stress impaired the cellular antioxidant system, leading to an imbalance in cellular homeostasis. However, SBP with a certain antioxidant activity inhibited reactive oxygen species (ROS) production, excessive intracellular Ca2+ level and abnormal apoptosis. It also restored the superoxide dismutase (SOD) and glutathione (GSH) levels and attenuated ethanol-induced oxidative damage and inflammation. SBP suppressed the activation of mitogen-activated protein kinase (MAPK) in ethanol-stimulated LO2 cells. It also regulated the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signalling pathway to protect LO2 cells from oxidative damage by promoting the expression of antioxidant enzymes, such as heme oxygenase-1 (HO-1). Furthermore, the metabolomics approach demonstrated nine different biomarkers and six metabolic pathways. In summary, the hepatoprotective mechanisms of SBP in vitro, which can be attributed to the upregulation of antioxidant substances and amino acid metabolism, attenuate ethanol-induced oxidative stress.

Plant lignans and their microbial metabolites, e.g., enterolactone (ENL), may affect bile acid (BA) metabolism through interaction with hepatic receptors. We evaluated the effects of a flaxseed lignan extract (50 mg/day secoisolariciresinol diglucoside) compared to a placebo for 60 days each on plasma BA concentrations in 46 healthy men and women (20-45 years) using samples from a completed randomized, crossover intervention. Twenty BA species were measured in fasting plasma using LC-MS. ENL was measured in 24-h urines by GC-MS. We tested for (a) effects of the intervention on BA concentrations overall and stratified by ENL excretion; and (b) cross-sectional associations between plasma BA and ENL. We also explored the overlap in bacterial metabolism at the genus level and conducted in vitro anaerobic incubations of stool with lignan substrate to identify genes that are enriched in response to lignan metabolism. There were no intervention effects, overall or stratified by ENL at FDR < 0.05. In the cross-sectional analysis, irrespective of treatment, five secondary BAs were associated with ENL excretion (FDR < 0.05). In vitro analyses showed positive associations between ENL production and bacterial gene expression of the bile acid-inducible gene cluster and hydroxysteroid dehydrogenases. These data suggest overlap in community bacterial metabolism of secondary BA and ENL.

Abstract
Herpetotriol, a typical lignan in Herpetospermum pedunculosum Wall's seeds that has long been used to treat icterhepatitis and indigestion and other related diseases in Tibet, is of potential hepatoprotection. This study aims to study the pharmacokinetics features of herpetotriol, including the blood drug concentration - time curve and tissue distribution. The ultrahigh-performance liquid chromatography with tandem mass spectrometry method was established to detect herpetotriol concentration in plasma and tissues, and the method showed good linearity from 10 to 2000 ng/mL (r ≥ 0.9972) and sensitivity (≥10 ng/mL). Our blood drug concentration - time curve indicated that herpetotriol was distributed quickly in rats with a Tmax value at about 0.083 h and eliminated rapidly with a clearance rate at 98.13 ± 8.05 and 137.04 ± 9.48 L·h-1·kg-1 with doses of 5 and 2.5 mg/kg, respectively. Although herpetotriol was detectable in all tested tissues, it has a higher concentration in liver than in heart, lung, spleen, and kidney, which is in line with its hepatoprotection. The pharmacokinetics features uncovered by the present study could provide more information for future pharmacological and toxicological study of herpetotriol.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cholestasis, caused by hepatic accumulation of bile acids, is a serious manifestation of liver diseases resulting in liver injury, fibrosis, and liver failure with limited therapies. Da-Huang-Xiao-Shi decoction (DHXSD) is a representative formula for treating jaundice and displays bright prospects in liver protective effect. AIM OF THE STUDY This study was designed to assess the effects and possible mechanisms of DHXSD against alpha-naphthylisothiocyanate-induced liver injury based on ultra-high performance liquid chromatography-hybrid quadrupole-Orbitrap mass spectrometry (UHPLC-Q-Orbitrap MS) metabonomic approach. MATERIALS AND METHODS The effects of DHXSD on serum indices (TBIL, DBIL, AST, ALT, ALP, TBA, and γ-GT) and the histopathology of the liver were analyzed. Moreover, UHPLC-Q-Orbitrap MS was performed to identify the possible effect of DHXSD on metabolites. The pathway analysis was conducted to illustrate the pathways and network by which DHXSD treats cholestasis. RESULTS The results demonstrated that DHXSD could significantly regulate serum biochemical indices and alleviate histological damage to the liver. Twelve endogenous components, such as glycocholic acid, taurocholic acid and indoleacetaldehyde, were identified as potential biomarkers of the therapeutic effect of DHXSD. A systematic network analysis of their corresponding pathways indicates that the anti-cholestatic effect of DHXSD on alpha-naphthylisothiocyanate-induced cholestasis rats occurs mainly through regulating primary bile acid biosynthesis, arginine and proline metabolism, and arachidonic acid metabolism. CONCLUSIONS DHXSD has exhibited favorable pharmacological effect on serum biochemical indices and pathological observation on cholestatic model by partially regulating the perturbed pathways. Moreover, these findings may help better understand the mechanisms of disease and provide a potential therapy for cholestasis.

Abstract
BACKGROUND Sedum sarmentosum, which is recorded in Chinese Pharmacopoeia, has been applied clinically to treat liver and gallbladder diseases. PURPOSE This study aimed to explore the hepatoprotective effect of S. sarmentosum less polar extract (SSE) against ANIT-induced liver injury in rats, and the protective activity and mechanism of one major constituent isolated from this extract on D-GalN-induced human hepatic QSG7701 cell damage. METHODS Rats were divided into groups and then administrated intragastrically with SSE at doses of 100, 200 and 400 mg/kg for 7 days. They were modeled in the experiments with ANIT (70 mg/kg) to induce liver injury after the sixth day administration. The levels of serum biochemical markers ALT, AST, ALP, GGT/γ-GT, DBiL, TBiL, ALB, TP, and bile flow rate, as well as the histopathology of the liver tissue were used as indices of liver damage and measured. The inflammatory response and oxidative stress were thought to be key contributors to ANIT-induced liver injury in rats. Therefore, the inflammatory mediators (TNF-α, IFN-γ, IL-4) and oxidative stress (ROS, SOD, GSH-PX) were measured in the serum and liver homogenates, respectively. Next, phytochemical research was performed to produce the main component, and the isolated compound was evaluated for its hepatoprotective activity against QSG7701 cell injured by D-GalN through the measurement of cell viabilities, ALT, AST, IL-1β, TNF-α, IL-6, ROS, GSH-PX and SOD productions. Furthermore, the protein expression of the Nrf2 and NF-κB pathways were analyzed by western blotting. RESULTS SSE had an obvious effect on the decreases of ALT, AST, ALP, GGT/γ-GT, DBiL and TBiL levels, the increases of ALB and TP levels in serum, and the ANIT-induced deceleration in bile flow for liver injury. Meanwhile, SSE pretreatment alleviated ANIT-induced liver pathological injuries exhibited by HE stain of the liver. Moreover, SSE significantly suppressed levels of pro-inflammatory cytokines TNF-α and IFN-γ, and elevated level of anti-inflammatory cytokine IL-4 in serum. SSE also attenuated oxidative stress by reducing ROS level and by enhancing antioxidative enzymes (SOD and GSH-PX) activities after ANIT administration in liver tissue. Further, the major compound shown in HPLC was isolated from SSE. Its structure was identified by the spectroscopic data analysis and comparison with literature values. The principal constituent had potent protective effect on D-GalN-induced QSG7701 cells damage in a dose dependent manner with survival rates of 58.2% and 69.5% at 10 μM and 20 μM, respectively. Its cytoprotective effect was associated with the reduction of ALT, AST, IL-1β, TNF-α, IL-6 and ROS levels, and the elevation of GSH-PX and SOD productions in QSG7701 cells induced by D-GalN. Western blotting showed that this compound enhanced the expression of Nrf2, HO1, NQO1 and GCLC, and inhibited D-GalN-induced IκBα and NF-κB p65 phosphorylation. CONCLUSIONS Current study showed that SSE treatment exerted a protective effect on ANIT-induced liver injury. The main compound δ-amyrone isolated from the extract was characterized as the effective component with hepatoprotective activity by promoting Nrf2 antioxidant defense and suppressing NF-κB inflammatory response.

Abstract
Around 70-80% of drugs used in traditional Tibetan medicine (TTM) come from Qinghai Tibet Plateau, the majority of which are plants. The biological and medicinal culture diversity on Qinghai Tibet Plateau are amazing and constitute a less tapped resource for innovative drug research and development. Meanwhile, the problem of the exhausting Tibetan medicine resources is worrying. Here, the latest awareness, as well as the gaps of the traditional Tibetan medicinal plant issues in drug development and clinical usage of TTM compounds, was systematically reviewed and highlighted. The TTM resource studies should be enhanced within the context of deeper and more extensive investigations of molecular biology and genomics of TTM plants, phytometabolites and metabolomics and ethnopharmacology-based bioactivity, thus enabling the sustainable conservation and exploitation of Tibetan medicinal resource.

Yinchenhao Decoction Ameliorates Alpha-Naphthylisothiocyanate Induced Intrahepatic Cholestasis in Rats by Regulating Phase II Metabolic Enzymes and Transporters. Front Pharmacol 2018; 9:510.

Abstract
Yinchenhao Decoction (YCHD), a famous traditional Chinese formula, has been used for treating cholestasis for 1000s of years. The cholagogic effect of YCHD has been widely reported, but its pharmacodynamic material and underlying therapeutic mechanism remain unclear. By using ultra-high-performance liquid chromatography (UHPLC)-quadrupole time-of-flight mass spectrometry, 11 original active components and eight phase II metabolites were detected in rats after oral administration of YCHD, including three new phase II metabolites. And it indicated that phase II metabolism was one of the major metabolic pathway for most active components in YCHD, which was similar to the metabolism process of bilirubin. It arouses our curiosity that whether the metabolism process of YCHD has any relationship with its cholagogic effects. So, a new method for simultaneous quantitation of eight active components and four phase II metabolites of rhein, emodin, genipin, and capillarisin has been developed and applied for their pharmacokinetic study in both normal and alpha-naphthylisothiocyanate (ANIT)-induced intrahepatic cholestasis rats. The results indicated the pharmacokinetic behaviors of most components of YCHD were inhibited, which was hypothesized to be related to different levels of metabolic enzymes and transporters in rat liver. So dynamic changes of intrahepatic enzyme expression in cholestasis and YCHD treated rats have been monitored by an UHPLC-tandem mass spectrometry method. The results showed expression levels of UDP-glucuronosyltransferase 1-1 (UGT1A1), organic anion-transporting polypeptide 1A4 (OATP1A4), multidrug resistance-associated protein 2 (MRP2), multidrug resistance protein 1, sodium-dependent taurocholate cotransporter, and organic anion-transporting polypeptide 1A2 were significantly inhibited in cholestasis rats, which would account for reducing the drug absorption and the metabolic process of YCHD in cholestatic rats. A high dose (12 g/kg) of YCHD remarkably increased the expression of UGT1A1, bile salt export pump, MRP2, OATP1A4 in cholestasis rats presented it exhibited the greatest ameliorative effect on cholestasis, also particularly in histopathological examination and reducing levels of alanine transaminase, aspartate transaminase, total bilirubin, direct bilirubin, and total bile acid. Considering the metabolic process of bilirubin in vivo, the choleretic effect of YCHD is proven to be related to its regulatory action on expression of metabolic enzymes and transporters in cholestatic liver.
