A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata(PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride(TG), aspartate aminotransferase(AST), alanine aminotransferase(ALT), and malondialdehyde(MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.展开更多

METHODS： Forty Wistar rats were divided randomly into control group and model group. All model rats were given 200 mL/L CCI4 （2 mL/Kg, po） twice a week for 8 wk. Four weeks after CCh treatment, thirty model rats were further divided randomly into 3 subgroups： CCh and two FMAC subgroups. Rats in CCI4 and 2 FMAC subgroups were treated with FMAC 0, 0.5 and 1.0 g/kg, daily via gastrogavage beginning at the fitch week and the end of the eighth week. Spleen weight, blood synthetic markers （albumin and prothrombin time） and hepatic malondialdehyde （MDA） and hydroxyproline （HP） concentrations were determined. Expression of collagen I, tissue inhibitor of metalloproteinases （TIMP）-1 and transforming growth factor β1 （TGF-β1） mRNA were detected by RTPCR. Histochemical staining of Masson＇s trichrome was performed. RESULTS： CCI4 caused liver fibrosis, featuring increased prothrombin time, hepatic MDA and HP contents, and spleen weight and decreased plasma albumin level. Compared with CCh subgroup, FMAC subgroup （1 g/kg） significantly decreased the prothrombin time （36.7±7.2 and 25.1±10.2 in CCh and FMAC groups, respectively, P〈 0.05） and increased plasma albumin concentration （22.7± 1.0 and 30.7±2.5 in CCk and FMAC groups, respectively, P 〈 0.05）. Spleen weight was significantly lower in rats treated with CCh and FMAC （1 g/kg） compared to CCh treated rats only （2.7±0.1 and 2.4±0.2 in CCk and FMAC groups, respectively, P〈0.05）. The amounts of hepatic MDA and HP in CCI4± FAMC （1 g/kg） subgroup were also lower thanthose in CCh subgroup （MDA： 3.9±0.1 and 2.4±0.6 in CCh and CCI4 ＋ FMAC groups, respectively, P〈 0.01; HP： 1730.7±258.0 and 1311.5±238.8 in CCI4 and CCI4＋FMAC groups, respectively, P〈0.01）. Histologic examinations showed that CCI4＋FMAC subgroups had thinner or less fibrotic septa than CCh group. RT-PCR analysis indicated that FMAC （1 g/kg） reduced mRNA levels of collagen I, TIMP-1 and TGF-β1 （collagen I： 5.63±2.08 and 1.78±0.48 in CCh and CCI4＋FMAC groups, respectively, P〈0.01; TIMP-1： 1.70±0.82 and 0.34±0.02 in CCh and CCI4 ＋ FMAC groups, respectively, P〈0.01; TGF-β1：38.03±11.9 and 4.26±2.17 in CCh and CCI4＋FMAC groups, respectively, P〈0.01） in the CCI4-treated liver. CONCLUSION： It demonstrates that FMAC can retard the progression of liver fibrosis induced by CCh in rats.展开更多

This paper aims to clarify the metabolites which are present in tumor tissues after oral administration of AC in Sarcoma-180 tumor-bearing mice, as well as their contents in tumors. Methods： Tumors of Sarcoma-180 tumor-bearing mice were obtained at 1 h and 4 h after oral administration of AC extract, and the metabolites in the tumor homogenate samples were characterized using UHPLC-orbitrap/MS analysis. Then, a fully validated LC-MS/MS method was developed for quantitative analysis of the most abundant compounds in tumor tissues, namely （25R/S）-antcin H. Results： A total of 33 compounds were characterized in tumor homogenate samples including 28 prototypes of triterpenoids and 5 metabolites. Among them, （25R）-antcin H and （25S）-antcin H had the highest contents of 2.03 and 0.66 μg/g tumor tissues for the 1 h group, and 2.04 and 0.59 μg/g tumor tissues for the 4 h group, respectively. It was obvious that （25R）-antcin H had higher tumor affinity than （25S）-antcin H, since the content of （25R）-antcin H was lower than that of （25S）-antcin H in AC extract （P 〈 0.01）. Conclusion： Triterpenoids can enter tumor tissues after oral administration of AC. Particularly, （25R）-antcin H showed higher exposure to tumor than （25S）-antcin H. These compounds could contribute to the anticancer activities of AC.展开更多

文摘Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata(PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride(TG), aspartate aminotransferase(AST), alanine aminotransferase(ALT), and malondialdehyde(MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.

文摘Antrodia cinnamomea is extensively used as a traditional medicine to prevention and treatment of liver cancer.However,its comprehensive chemical fingerprint is uncertain,and the mechanisms,especially the potential therapeutic target for anti-hepatocellular carcinoma(HCC)are still unclear.Using UPLC-Q-TOF/MS,139 chemical components were identified in A.cinnamomea dropping pills(ACDPs).Based on these chemical components,network pharmacology demonstrated that the targets of active components were significantly enriched in the pathways in cancer,which were closely related with cell proliferation regulation.Next,HCC data was downloaded from Gene Expression Omnibus database(GEO).The Cancer Genome Atlas(TCGA)and Dis Ge NET were analyzed by bioinformatics,and 79 biomarkers were obtained.Furtherly,nine targets of ACDP active components were revealed,and they were significantly enriched in PI3 K/AKT and cell cycle signaling pathways.The affinity between these targets and their corresponding active ingredients was predicted by molecular docking.Finally,in vivo and in vitro experiments showed that ACDPs could reduce the activity of PI3 K/AKT signaling pathway and downregulate the expression of cell cycle-related proteins,contributing to the decreased growth of liver cancer.Altogether,PI3 K/AKT-cell cycle appears as the significant central node in anti-liver cancer of A.Cinnamomea.

文摘Antrodia cinnamomea is an important edible and medicinal mushroom,and it exhibits multiple biological activities,such as hepatoprotection,antitumor,antivirus,and immunoregulation.Polysaccharides are the main products of A.cinnamomea in submerged fermentation.In this work,exopolysaccharides from A.cinnamomea(AEPS)were extracted and purified by alcohol precipitation and Sevag method.Composition analysis revealed that AEPS were primarily composed of three distinct polysaccharides with mean molecular weights of 1,013,233,and 28,743 kDa,accounting for 78%,18%,and 4%of AEPS,respectively.The AEPS haveβ-type glycosidic bonds and relatively strong resistance to digestion.In vivo experiments showed that the intragastric administration of AEPS in mice with medium dose(0.25 g/kg body weight of mice)has the following effects:remarkably alleviate lincomycin hydrochloride(LIH)-induced injuries to immune organs;enhance the relative abundance of beneficial microorganisms such as Lactobacillus,Roseburia,Ligilactobacillus,and Lachnospiraceae_NK4A136_group in the intestinal tract;greatly reduce the levels of inflammatory cytokines IL-6 and TNF-αin serum and the relative abundances of harmful microbes such as Enterococcus and Shigella;regulate the balance of the gut microflora;and relieve LIH-induced symptoms such as diarrhea,inflammation,and weight loss.These findings might represent a new alternative to develop novel multifunctional carbohydrate prebiotics.
