Polyporenic acid C induces caspase-8-mediated apoptosis in human lung cancer A549 cells
Mol Carcinog 2009 Jun;48(6):498-507.PMID:18973184DOI:10.1002/mc.20487.
Lung cancer continues to be the leading cause of cancer-related mortality worldwide. This warrants the search for new and effective agents against lung cancer. We and others have recently shown that lanostane-type triterpenoids isolated from the fungal species Poria cocos (P. cocos) can inhibit cancer growth. However, the mechanisms responsible for the anticancer effects of these triterpenoids remain unclear. In this study, we investigated the effect of Polyporenic acid C (PPAC), a lanostane-type triterpenoid from P. cocos, on the growth of A549 nonsmall cell lung cancer cells (NSCLC). The results demonstrate that PPAC significantly reduced cell proliferation via induction of apoptosis as evidenced by sub-G1 analysis, annexin V-FITC staining, and increase in cleavage of procaspase-8, -3, and poly(ADP-ribose)-polymerase (PARP). However, unlike our previously reported lanostane-type triterpenoid, pachymic acid, treatment of cells with PPAC was not accompanied by disruption of mitochondrial membrane potential and increase in cleavage of procaspase-9. Further, PPC-induced apoptosis was inhibited by caspase-8 and pan caspase inhibitors but not by a caspase-9 inhibitor. Taken together, the results suggest that PPAC induces apoptosis through the death receptor-mediated apoptotic pathway where the activation of caspase-8 leads to the direct cleavage of execution caspases without the involvement of the mitochondria. Furthermore, suppressed PI3-kinase/Akt signal pathway and enhanced p53 activation after PPAC treatment suggests this to be an additional mechanism for apoptosis induction. Together, these results encourage further studies of PPAC as a promising candidate for lung cancer therapy.
[Quality evaluation of Poria based on specific chromatogram and quantitative analysis of multicomponents]
Zhongguo Zhong Yao Za Zhi 2019 Apr;44(7):1371-1380.PMID:31090294DOI:10.19540/j.cnki.cjcmm.20181220.005.
HPLC specific chromatograms of Poria were established, and the concentrations of 10 triterpenoids(16α-hydroxydehydrotrametenolic acid, poricoic acid B, dehydrotumulosic acid, poricoic acid A, Polyporenic acid C, poricoic acid AM, 3-O-acetyl-16α-hydroxydehydrotrametenolic acid, dehydropachymic acid, pachymic acid, and dehydrotrametenolic acid) were simultaneously determined. Chromatographic analysis was conducted on a Welch Ultimate XB C_(18) column(4.6 mm × 250 mm,5 μm). Acetonitrile solution(contain 3% tetrahydrofuran)(A) and 0.1% formic acid aqueous solution(B) were used as the mobile phase with gradient elution at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the injection volume was 20 μL. The experimental data were analyzed by the SPSS 22.0 and GraphPad Prism 7.0. The established triterpenoids fingerprints were specific, and the 10 components were well separated and showed good linearity(r≥0.999 6) within the concentration ranges tested. The mean recoveries were between 98.53%-103.8%(RSD 1.7%-2.7%). The method was specific and repeatable, and could be used for identification and quality evaluation of Poria. The results showed that the contents of 10 triterpenoids were positively correlated with each other. The contents of 10 triterpenoids of samples collected from producing areas were higher than that collected from markets. The total contents of 10 triterpenoids of samples collected from Hubei and Yunnan province were slightly higher than that from Anhui province, but the contents of samples from Anhui province were varied in smaller ranges.
Untargeted Metabolomics and Targeted Quantitative Analysis of Temporal and Spatial Variations in Specialized Metabolites Accumulation in Poria cocos (Schw.) Wolf (Fushen)
Front Plant Sci 2021 Sep 21;12:713490.PMID:34621284DOI:10.3389/fpls.2021.713490.
Poria cocos (Schw.) Wolf is a saprophytic fungus that grows around the roots of old, dead pine trees. Fushen, derived from the sclerotium of P. cocos but also containing a young host pine root, has been widely used as a medicine and food in China, Japan, Korea, Southeast Asian countries, and some European countries. However, the compound variations at the different growth periods and in the different parts of Fushen have not previously been investigated. In this study, an untargeted metabolomics approach based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) and targeted quantitative analysis was utilized to characterize the temporal and spatial variations in the accumulation of specialized metabolites in Fushen. There were 119 specialized metabolites tentatively identified using the UPLC-Q/TOF-MS. The nine growth periods of Fushen were divided into four groups using partial least squares discrimination analysis (PLS-DA). Four different parts of the Fushen [fulingpi (FP), the outside of baifuling (BO), the inside of baifuling (BI), and fushenmu (FM)] were clearly discriminated using a PLS-DA and orthogonal partial least squares discrimination analysis (OPLS-DA). Markers for the different growth periods and parts of Fushen were also screened. In addition, the quantitative method was successfully applied to simultaneously determine 13 major triterpenoid acids in the nine growth periods and four parts. The quantitative results indicated that the samples in January, March, and April, i.e., the late growth period, had the highest content levels for the 13 triterpenoid acids. The pachymic acid, dehydropachymic acid, and dehydrotumulosic acid contents in the FM were higher than those in other three parts in March, whereas the poricoic acid B, poricoic acid A, Polyporenic acid C, dehydrotratrametenolic acid, dehydroeburicoic acid, and eburicoic acid in FP were higher beginning in October. These findings reveal characteristics in temporal and spatial distribution of specialized metabolites in Fushen and provide guidance for the identification of harvesting times and for further quality evaluations.
Effects of Poria cocos extract on metabolic dysfunction-associated fatty liver disease via the FXR/PPARα-SREBPs pathway
Front Pharmacol 2022 Oct 5;13:1007274.PMID:36278226DOI:10.3389/fphar.2022.1007274.
Despite the increase in the global prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD), no approved drug currently exists for the disease. Poria cocos (Schw.) Wolf (P. cocos) is a medicinal mushroom belonging to a family of polyporaceae widely used in TCM clinics to protect the liver and treat obesity. However, its efficacy, practical components, and underlying mechanism against MAFLD are yet to be determined. In this study, we evaluated the effects of Poria cocos (P. cocos) ethanol extract (EPC) on hepatic dyslipidemia, steatosis, and inflammation by both bioinformatics analysis and MAFLD rats induced by HFD feeding. We found EPC treatment dramatically reduced lipid accumulation, inflammatory cell infiltration, and liver injury. EPC reduced serum TC, TG levels, and hepatic TG, TBA, and NEFA contents. UHPLC Q-Trap/MS examination of BA profiles in serum and feces showed that EPC increased fecal conjugated BAs, decreased free BAs, and improved BA metabolism in HFD-fed rats. Western blot and RT-qPCR analysis showed that EPC could activate hepatic FXR and PPARα expression and reduce CYP7A1 and SREBP-1c expression. Systemic pharmacology combined with molecular docking suggested that poricoic acid B and Polyporenic acid C, the major active compounds in EPC, could ameliorate lipid homeostasis by activating the nuclear receptor PPARα. We further confirmed their inhibition effects of lipid droplet deposition in steatized L-02 hepatocytes. In summary, EPC alleviated HFD-induced MAFLD by regulating lipid homeostasis and BA metabolism via the FXR/PPARα-SREBPs signaling pathway. P. cocos triterpenes, such as poricoic acid B and Polyporenic acid C, were the characteristic substances of P. cocos for the treatment of MAFLD.
[Simultaneous determination of six triterpenoid acids from Guizhi Fuling capsules by UPLC-MS/MS]
Zhongguo Zhong Yao Za Zhi 2017 Sep;42(17):3368-3373.PMID:29192448DOI:10.19540/j.cnki.cjcmm.20170719.006.
To establish a UPLC-MS/MS method for simultaneous determination of six triterpenoid constituents (pachymic acid, dehydropachymic acid, dehydrotumulosic acid, Polyporenic acid C, dehydroeburicoic acid and dehydrotra metenolic acid) in Guizhi Fuling capsules (GFC). Chromatographic analysis was conducted on Agilent Porosheell 120 SB-C₁₈ column (4.6 mm×150 mm, 2.7 μm), with 0.1% formic acid aqueous solution-methanol as the mobile phase for gradient elution at a flow rate of 0.4 mL•min-1. The column temperature was 30 ℃ and the sample size was 5 μL. The samples were analyzed by tandem mass spectrometer with negative electrospray ionization (ESI) source, and monitored under a multiple reaction monitoring (MRM) mode, with the quantitative ion pairs m/z 527.8→465.5 (pachymic acid), m/z 525.6→465.6 (dehydropachymic acid), m/z 483.4→337.3 (dehydrotumulosic acid), m/z 481.5→419.5 (Polyporenic acid C), m/z 467.4→337.1 (dehydroeburicoic acid), m/z 453.4→337.0 (dehydrotra metenolic acid). Six triterpenoid acids showed good linear relationships within the investigated concentration ranges (r> 0.996 8), with RSDs of precision less than 6.2%, and all RSDs of repeatability less than 5.9%. The average recovery rate was 97.90%, 100.2%, 99.60%, 101.7%, 102.6% and 103.0% respectively. The method was rapid, accurate, repeatable and could be used as a method for quantitative determination of triterpenoid acids in Chinese medicine prescriptions, providing a reference method for the quality control of Guizhi Fuling capsules and providing a reference for the content determination for Chinese medicine prescriptions containing Poria cocos.
