PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 128:155505. [PMID: 38547616 DOI: 10.1016/j.phymed.2024.155505] [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: 10/30/2023] [Revised: 01/30/2024] [Accepted: 02/28/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Fatty liver disease (FLD) poses a significant global health concern worldwide, with its classification into nonalcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (AFLD) contingent upon the presence or absence of chronic and excessive alcohol consumption. The absence of specific therapeutic interventions tailored to FLD at various stages of the disease renders its treatment exceptionally arduous. Despite the fact that FLD and hyperlipidemia are intimately associated, there is still debate over how lipid-lowering medications affect FLD. Proprotein Convertase Subtilisin/ Kexin type 9 (PCSK9) is a serine protease predominantly synthesized in the liver, which has a crucial impact on cholesterol homeostasis. Research has confirmed that PCSK9 inhibitors have prominent lipid-lowering properties and substantial clinical effectiveness, thereby justifying the need for additional exploration of their potential role in FLD. PURPOSE Through a comprehensive literature search, this review is to identify the relationship and related mechanisms between PCSK9, lipid metabolism and FLD. Additionally, it will assess the pharmacological mechanism and applicability of PCSK9 inhibitors (including naturally occurring PCSK9 inhibitors, such as conventional herbal medicines) for the treatment of FLD and serve as a guide for updating the treatment protocol for such conditions. METHODS A comprehensive literature search was conducted using several electronic databases, including Pubmed, Medline, Embase, CNKI, Wanfang database and ClinicalTrials.gov, from the inception of the database to 30 Jan 2024. Key words used in the literature search were "fatty liver", "hepatic steatosis", "PCSK9", "traditional Chinese medicine", "herb medicine", "botanical medicine", "clinical trial", "vivo", "vitro", linked with AND/OR. Most of the included studies were within five years. RESULTS PCSK9 participates in the regulation of circulating lipids via both LDLR dependent and independent pathways, and there is a potential association with de novo lipogenesis. Major clinical studies have demonstrated a positive correlation between circulating PCSK9 levels and the severity of NAFLD, with elevated levels of circulating PCSK9 observed in individuals exposed to chronic alcohol. Numerous studies have demonstrated the potential of PCSK9 inhibitors to ameliorate non-alcoholic steatohepatitis (NASH), potentially completely alleviate liver steatosis, and diminish liver impairment. In animal experiments, PCSK9 inhibitors have exhibited efficacy in alleviating alcoholic induced liver lipid accumulation and hepatitis. Traditional Chinese medicine such as berberine, curcumin, resveratrol, piceatannol, sauchinone, lupin, quercetin, salidroside, ginkgolide, tanshinone, lunasin, Capsella bursa-pastoris, gypenosides, and Morus alba leaves are the main natural PCS9 inhibitors. Excitingly, by inhibiting transcription, reducing secretion, direct targeting and other pathways, traditional Chinese medicine exert inhibitory effects on PCSK9, thereby exerting potential FLD therapeutic effects. CONCLUSION PCSK9 plays an important role in the development of FLD, and PCSK9 inhibitors have demonstrated beneficial effects on lipid regulation and FLD in both preclinical and clinical studies. In addition, some traditional Chinese medicines have improved the disease progression of FLD by inhibiting PCSK9 and anti-inflammatory and antioxidant effects. Consequently, the inhibition of PCSK9 appears to be a promising therapeutic strategy for FLD.

Abstract
Phytochemical investigation of the seeds of Capsella bursa-pastoris led to the isolation of four organosulfur compounds. There were two new compounds, 10-methylsulfinyl-decanamide (1) and 11-methylsulfinyl-undecanamide (2), along with two known compounds (3 - 4), which all have a sulfoxide group and an amide or a nitrile group. Their chemical structures were elucidated by analysing UV, IR, ESI-MS and NMR spectroscopy. In addition, compounds 1 - 4 were evaluated for their anti-inflammatory activities by using LPS-induced RAW 264.7 cells. Compounds 1 - 4 exhibited potential anti-inflammatory activities on NO release characterised by decreasing the mRNA expression levels of inducible NO synthase (iNOS), cytokines cyclooxygenase-2 (COX-2) and interleukin 6 (IL-6).

Abstract
Epigenetic regulation by histone acetyltransferase (HAT) is associated with various biological processes and the progression of diseases, including nonalcoholic fatty liver disease (NAFLD). The objective of this study was to investigate whether the hypolipidemic properties of black mulberry (Morus atropurpurea Roxb.) fruit extract (BME) contribute toward protection against NAFLD by HAT inhibition. HepG2 cells were treated with oleic and palmitic acids to induce lipid accumulation, which was significantly attenuated by the treatment with BME at 50 and 100 μg/mL. BME also markedly reduced the expression of proteins associated with lipogenesis, which was attributed to the BME-mediated downregulation of lipogenic genes in HepG2 cells. BME significantly inhibited in vitro total HAT and p300 activities. In addition, BME suppressed total acetylated lysine as well as specific histone acetylation of proteins H3K14 and H3K27 in HepG2 cells. Mice were then fed with either a chow diet or western diet (WD), with or without BME (1%, w/w) supplementation, for 12 weeks to confirm hypolipidemic activity of BME. BME attenuated serum nonesterified fatty acids and low-density lipoprotein (LDL) cholesterol levels, which was likely associated with the downregulation of hepatic lipogenic gene expression in WD-fed obese mice. Taken together, the hypolipidemic activity of BME was observed in HepG2 cells treated with fatty acids as well as in livers of obese mice, and the hepatoprotection of BME is likely associated with the inhibition of acetylation. Further investigation is warranted to determine whether BME can be developed into an efficacious dietary intervention to attenuate the progression of NAFLD by epigenetic regulation in clinical settings.

The Cholesterol-Lowering Effect of Capsella Bursa-Pastoris Is Mediated via SREBP2 and HNF-1α-Regulated PCSK9 Inhibition in Obese Mice and HepG2 Cells. Foods 2021; 10:foods10020408.

Abstract
The objective of the present study was to investigate the mechanism by which capsella bursa-pastoris ethanol extract (CBE), containing 17.5 milligrams of icaritin per kilogram of the extract, and icaritin, mediate hypocholesterolemic activity via the low-density lipoprotein receptor (LDLR) and pro-protein convertase subtilisin/kexin type 9 (PCSK9) in obese mice and HepG2 cells. CBE significantly attenuated serum total and LDL cholesterol levels in obese mice, which was associated with significantly decreased PCSK9 gene expression. HepG2 cells were cultured using delipidated serum (DLPS), and CBE significantly reduced PCSK9 and maintained the LDLR level. CBE co-treatment with rosuvastatin attenuated statin-mediated PCSK9 expression, and further increased LDLR. The icaritin contained in CBE decreased intracellular PCSK9 and LDLR levels by suppressing transcription factors SREBP2 and HNF-1α. Icaritin also significantly suppressed the extracellular PCSK9 level, which likely contributed to post-translational stabilization of LDLR in the HepG2 cells. PCSK9 inhibition by CBE is actively attributed to icaritin, and the use of CBE and icaritin could be an alternative therapeutic approach in the treatment of hypercholesterolemia.

Abstract
Shepherd's purse as a wild vegetable is getting more and more attention on health benefits. Water extract of shepherd's purse (WESP) was prepared and analyzed for the chemical constituents. The mice were fed high-fructose (HF) diet and treated with WESP at 50, 100 and 200 mg/kg·bw for 8 weeks. The HF-fed mice receiving WESP exhibited the inhibitions against abnormal weight gain, hepatic fat accumulation and lipid metabolic by down-regulating FAS and ACC expressions. WESP also significantly alleviated hyperglycemia, oxidative stress, and inflammatory response by regulating of NF-κB pathway. Moreover, WESP dose-dependently increased the acetic, propionic, and butyric acids levels in HF-fed mice. Furthermore, WESP significantly alleviated the HF-induced gut dysbiosis by reducing the ratio of Firmicutes to Bacteroidetes and increasing the abundance of potential beneficial bacteria. Our findings indicate that WESP may be an effective dietary supplement for preventing the liver damage.

Abstract
Herein, an electrochemical method to detect histone acetyltransferases activity (HAT) has been developed based on the reduction of G-Quadruplex-Cu(ii) metalloenzyme activity. A G-quadruplex-Cu(ii) metalloenzyme has excellent peroxidase property, generating strong electrochemical signal. In the presence of HAT, it can catalyze substrate peptide acetylation and produce large amounts of Coenzyme A (CoA). The electrochemical signal of G-Quadruplex-Cu(ii) is weak due to the competitive combination between G-Quadruplex and CoA with Cu(ii), resulting in the direct quantitative detection of HAT. The detection limit for HAT is about 0.14 nM using this strategy and the cost is quite low since the developed assay method is label-free and antibody-free due to the use of low-cost DNA and Cu2+. Since this assay method can be employed to detect HAT in serum, it may be useful in disease diagnosis in the future.

Abstract
Standardized animal models represent one of the most valuable tools available to understand the mechanism underlying the metabolic syndrome (MetS) and to seek for new therapeutic strategies. However, there is considerable variability in the studies conducted with this essential purpose. This review presents an updated discussion of the most recent studies using diverse experimental conditions to induce MetS in rodents with unbalanced diets, discusses the key findings in metabolic outcomes, and critically evaluates what we have been learned from them and how to advance in the field. The study includes scientific reports sourced from the Web of Science and PubMed databases, published between January 2013 and June 2020, which used hypercaloric diets to induce metabolic disorders, and address the impact of the diet on metabolic parameters. The collected data are used as support to discuss variables such as sex, species, and age of the animals, the most favorable type of diet, and the ideal diet length to generate metabolic changes. The experimental characteristics propose herein improve the performance of a preclinical model that resembles the human MetS and will guide researchers to investigate new therapeutic alternatives with confidence and higher translational validity.

Abstract
Hepatic steatosis is the most common chronic liver disease in Western countries. Both genetic and environmental factors are known as causes of the disease although their underlying mechanisms have not been fully understood. This study investigated the association of DNA methylation with oleic acid-induced hepatic steatosis. It also examined effects of food components on DNA methylation in hepatic steatosis. Genome-wide DNA methylation of oleic acid (OA)-induced lipid accumulation in vitro cell model was investigated using reduced representation bisulfite sequencing. Changes of DNA methylation were also analyzed after treatment with food components decreasing OA-induced lipid accumulation in the model. We identified total 81 regions that were hypermethylated by OA but hypomethylated by food components or vice versa. We determined the expression of seven genes proximally located at the selected differentially methylated regions. Expression levels of WDR27, GNAS, DOK7, MCF2L, PRKG1, and CMYA5 were significantly different between control vs OA and OA vs treatment with food components. We demonstrated that DNA methylation was associated with expression of genes in the model of hepatic steatosis. We also found that food components reversely changed DNA methylation induced by OA and alleviated lipid accumulation. These results suggest that DNA methylation is one of the mechanisms causing the hepatic steatosis and its regulation by food components provides insights that may prevent or alleviate lipid accumulation.

Abstract
Shepherd's purse (Capsella bursa-pastoris (L.) Medik.), a wild herb as a traditional herbal medicine, has been proved with multiple healthy benefits. In this study, the chemical constituents of shepherd's purse were identified by UPLC-QTOF-MS/MS. The antioxidative and anti-inflammatory potential of shepherd's purse extract (SPE) were also investigated applying lipopolysaccharide- (LPS-) induced inflammation in RAW 264.7 macrophages and a carrageenan-induced mice paw edema model. Twenty-four chemical compounds were identified mainly including phenolic acids and flavonoids. The data also indicated SPE inhibited the productions of NO, PGE2, TNF-α, and IL-6 stimulated with LPS. In addition, SPE inhibited the increase of reactive oxygen species (ROS) and upregulated the expression of heme oxygenase-1 (HO-1). We further found that SPE inhibited the phosphorylation of P38 MAPK and activation of NF-κB. In vivo mice model also indicated that SPE showed strong antioxidative and anti-inflammatory activity.
