In conclusion, although 50 mg kg-1 of PA treatment has some toxic effect in vivo, no major toxicity was observed in tested animals from 25 mg kg-1 of PA treatment group. 1. Xie Q, Khaoustov VI, Chung CC, Sohn J, Krishnan B, Lewis DE, et al. Liver, spleen, kidney, lung and heart were harvested, fixed in 10% neutral-buffered formalin at 4°C for 24 h followed tissue processing overnight and then embedded in paraffin. Yang Y, Li C, Xiang X, Dai Z, Chang J, Zhang M, et al. Of course, these findings do not mean that pancreatic cancer patients can be cured by eating pine tree mushrooms. Images are representative of control and PA treatment (25 mg kg-1 and 50 mg kg-1) groups. Moreover, H&E staining results showed that 25 mg kg-1 of PA treatment did not demonstrate any abnormalities in liver, kidney, spleen, lung and heart tissues but there were obvious pathological changes in liver, kidney and spleen tissues from 50 mg kg-1 of PA treated mice (Fig 7).

Data was analyzed by 2-way ANOVA using cell line and treatment as factors plus the interaction of cell line and treatment. At the end of the experiment, animals were euthanized by CO2 inhalation. The microarray studies were carried out using the facilities of the Center for Medical Genomics at Indiana University School of Medicine. For example, significant upregulation of HSR gene expression was observed including genes encoding the heat shock 70kDa protein 6 (HSP70B') (HSPA6; 19.93-fold), heat shock 70kDa protein 1A (HSPA1A; 2.45-fold), DnaJ (Hsp40) homolog, subfamily A, member 4 (DNAJA4; 2.01-fold), heat shock 70kDa protein 1B (HSPA1B; 1.90-fold), DnaJ (Hsp40) homolog, subfamily B, member 1 (DNAJB1; 1.64-fold) and heat shock 70kDa protein 8 (HSPA8; 1.62-fold). Wrote the paper: SC DS. Exciting: Within just one day, the mushroom extract inhibited several different mechanisms by which pancreatic cancer proliferates—so that the cancer cells acted less aggressively and didn’t multiply as rapidly as they usually would. Cortex Moutan / Poria Cocos is used for Cancer, Bladder cancer, Bladder tumour, Pancreatic cancer, Inflammation, Oxidative stress, Viral infections and other conditions. Expressions of (A) HSPA6 and (B) CHOP in tumor tissues were determined by qRT-PCR and normalized to ACTB expression as described in Materials and methods. Pancreatic Cancer. Tumor sizes were measured by microcalipers 3 times per week and calculated for additional 5 weeks. Anti-Hsp70 was obtained from Enzo Life Sciences (Farmingdale, NY). For instance, the mushroom extract seemed to silence one particular gene, MMP-7, that is overactive in pancreatic cancer cells. Triptolide activates unfolded protein response leading to chronic ER stress in pancreatic cancer cells. Bortezomib, a potent and selective inhibitor of proteasome, sensitizes pancreatic cancer cells to ER stress-induced apoptosis and strongly enhances the antitumor activity of cisplatin [20]. Always consult a competent professional for answers specific to your questions and circumstances. 4 For instance, the mushroom extract seemed to silence one particular gene, MMP-7, that is overactive in pancreatic cancer cells. The RNA samples were reverse transcribed into cDNA using High Capacity cDNA Reverse Transcription Kit (Applied Biosystems, Foster City, CA). Quantification results showed approximately 3 fold increases in the expression of PARP cleavage in PANC-1 cells and 4 fold increases in MIA PaCa-2 cells by PA treatment comparing with their vehicle-treated controls (Fig ​(Fig1C1C and ​and1D1D). There are 36,000 transcripts (genes plus some variants) interrogated on the array. Recent studies suggested that bioactive compounds in mushrooms might protect against breast and skin cancer…so researchers set out to discover whether they also might hold promise against pancreatic cancer, for which there is no known cure. Here, *p≤0.025 was considered significant for the individual t-tests. *P<0.050 was considered to be significant when compared to control (n = 3) by Student t-test. PANC-1 and MIA PaCa-2 cells were exposed to different concentrations of PA for 24 h and the c-PARP was detected by western blot analysis. Xanthohumol activates the proapoptotic arm of the unfolded protein response in chronic lymphocytic leukemia, Cell death and endoplasmic reticulum stress: disease relevance and therapeutic opportunities. Pachymic acid (PA) is a purified triterpene extracted from medicinal fungus Poria cocos. It is induced by ATF3 in response to prolonged ER stress and is the downstream component of ATF4 [54, 56]. Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7 Shujie Cheng, Isaac Eliaz, Junfang Lin, and Daniel Sliva Abstract Poria cocos is a medicinal mushroom that is widely used in traditional Asian medicine. Here, we show that a characterized mixture of triterpenes extracted from P. cocos (PTE) and three purified triterpenes: pachymic acid (PA), dehydropachymic acid (DPA) and polyporenic acid C (PPAC) suppress the proliferation of the human pancreatic cancer cell lines Panc-1, MiaPaca-2, AsPc-1 and BxPc-3. Eye Health: Top Doc’s Integrated Approach, Face Value: Investing in Metals and Money. There is published evidence that lanostane-type triterpenes possess antioxidant and free radical scavenging activities, which may play an important role in reducing cancer risk [61]. Tauroursodeoxycholic acid reduces endoplasmic reticulum stress, trypsin activation, and acinar cell apoptosis while increasing secretion in rat pancreatic acini, Role of Poly(ADP-ribose) Polymerase (PARP) Cleavage in Apoptosis. A q-value program from Storey and Tibshirani was used to calculate false discovery rates. The stressed state of malignant cells makes them vulnerable to therapeutic strategies, which target molecular determinants of HSR or UPR or a combination of both to exacerbate enhanced stress in cancer selective therapy [10]. injection 3 times per week of vehicle or PA (25 mg kg-1 and 50 mg kg-1) of body weight for additional 5 weeks.

Moreover, two transcription factors involved in UPR system, XBP1and ATF4, were significantly activated as well (Fig 2A–2D). ALP, alkaline phosphatase; ALT, alanine aminotransferase; AST, aspartate aminotransferase; T protein, total protein. Fu Ling(concentrated Extract Powder)(poria Cocos Fungus. The ePub format uses eBook readers, which have several "ease of reading" features Extraction and puri cation. All the statistical analysis was performed using SigmaPlot 11.2.0 (Systat Software Inc., San Jose, CA). Supplements, FBS and HS were obtained from Gibco BRL (Grand Island, NY). Total-RNA from each sample was isolated with RNeasy Mini Kit (Qiagen, Valencia, CA) according to the manufacturer’s protocol. 2011 May; 77(7):681-91. (C) Expressions of ATF4 and CHOP in tumor tissues were detected by western blot analysis. Poria cocos Wolf is a fungus that belongs to the Polyporaceae family, and is extensively distributed in East Asia, including Korea, China, and Japan, and can be commonly seen on the roots and dead ... melanoma, pancreatic cancer, prostate cancer, and ovarian cancer cells [7,11–13]. Under these conditions, protein folding is disrupted and unfolded or misfolded proteins accumulate in the ER lumen, which lead to ER stress [8, 9]. Alosi JA, McDonald DE, Schneider JS, Privette AR, McFadden DW. These seemingly contradicted results show that the activities of different triterpene acids are complicated, depending on the various structures, cell types, treatment times, concentrations and so on. Gene expression levels were normalized and analyzed using Microarray Data Portal (MDP) by 2-way ANOVA using cell line and treatment as factors plus the interaction of cell line and treatment. The expression of HSR genes, such as HSPA6, HSPA1A, DNAJA4, HSPA1B, DNAJB1 and HSPA8, were significantly upregulated to overcome the effects of ER stress [49]. Statistical comparisons between two groups of data were carried out using Student's t-test and comparisons between many groups of data were carried out using ANOVA with the significance level adjusted using the repeated t-tests with Bonferroni correction. Inhibition of proliferation by omega-3 fatty acids in chemoresistant pancreatic cancer cells, Cytotoxic therapy for advanced pancreatic adenocarcinoma. Apoptosis inducing effects of PA were further confirmed by increased expression of cleaved PARP (c-PARP). Data were compared by ANOVA with Bonferroni correction for the significant level. Effect of the basidiomycete Poria cocos on experimental dermatitis and other inflammatory conditions. The apoptosis inducting effects of PA in gemcitabine-resistant PANC-1 and MIA PaCa-2 were determined by the induction of nuclear DNA fragmentation using ELISA [38]. A research from Indiana University stated that a traditional remedy extracted from pine-bearing Poria Cocos, a type of medical mushrooms, can block the MMP gene. To assess whether non-toxic dose of PA mediated tumor growth suppression was associated with induction of ER stress, RNA of tumors from control and 25 mg kg-1 of PA treated mice were isolated and subjected to quantitative RT-PCR. Data were presented as mean ± SD. Poria cocos has been shown to be able to promote antitumor 2-5, antioxidant 6, antibacterial 7, antihyperglycemia 8,9 and anti-inflammatory 10,11 activities. The activated PERK kinase phosphorylates the alpha subunit of the eukaryotic initiation factor 2 (eIF2α), which results in the first step in the UPR: decreased translation initiation and protein synthesis [14, 15]. Data are mean ± SD (n = 6–12). The tumors were harvested and fixed in 10% neutral-buffered formalin at 4°C for 24 h or snap frozen and stored separately in liquid nitrogen. Analysis of the relative quantity gene expression (RQ) of HSPA6 and CHOP was normalized by ACTB expression and was performed using the 2-ΔΔCt method [32]. Expressions of (D) ATF4 and (E) CHOP were quantified with statistical analysis. Cancer Research Laboratory, Methodist Research Institute, Indiana University Health, Indianapolis, Indiana, United States of America. Both systems act as quality control processes to facilitate protein folding and suppress protein synthesis [10, 11]. Pancreatic cancer moves fast—many of its victims die within months of being diagnosed, and the five-year survival rate is dismal, not even reaching 5%. Quantification results showed approximately 59% increase of apoptotic bodies in 25 mg kg-1 group and 2 fold increase in 50 mg kg-1 group comparing with control (Fig 5B). Poria-cocos mushrooms capsules achieved obvious effects in the treatment of uterine fibroids, pelvic inflammatory disease, dysmenorrheal, endometriosis, ovarian cysts, breast hyperplasia and other gynecological diseases.2. Induced ER stress was confirmed by increasing expression of XBP-1s, ATF4, Hsp70, CHOP and phospho-eIF2α. 2011–07). Our content is further subject to our Terms and Conditions. Harding HP, Zhang Y, Bertolotti A, Zeng H, Ron D. Perk is essential for translational regulation and cell survival during the unfolded protein response, Dimerization and release of molecular chaperone inhibition facilitate activation of eukaryotic initiation factor-2 kinase in response to endoplasmic reticulum stress. Gemcitabine results in a tumor response rate of 12% and offers a median survival time of 5 months, which means that the best current treatment offers very modest benefits [34]. Data are mean ± SD (n = 10–15). Thank you! However, AST, albumin and total protein levels were significantly increased in 50 mg kg-1 of PA treated mice (Table 2). Animal studies suggest potential uses as an immunomodulator and anti-inflammatory agent, and in the management of cancer and diabetes; however, clinical studies are lacking. found the overexpression of GRP78 in the human pancreatic cancer cell lines and tissue samples. Among of them, PERK appears to play the major role in the face of mild ER stress. Zhu W, Li J, Wu S, Li S, Le L, Su X, et al. 25 mg kg-1 and 50 mg kg-1 of PA both obviously suppressed the growth of chemotherapy resistant pancreatic tumors (Fig ​(Fig4A4A and ​and4B).4B). However, if the stress cannot be resolved, signaling through ATF6, IRE1 and PERK trigger pro-apoptotic response through activation of downstream molecules, such as transcription factor C/EBP homologous protein (CHOP), which further induce apoptosis during prolonged ER stress [11]. Although PA inhibits growth of chemotherapy resistant pancreatic tumors in vivo, its possible toxicity must be tested comprehensively. H&E staining revealed significantly more brown apoptotic bodies in the tumor tissues from PA treated mice as compared with controls (Fig 5A), indicating that tumor growth inhibition was due to apoptosis induced by PA treatment. the display of certain parts of an article in other eReaders. Lee SM, Lee YJ, Yoon JJ, Kang DG, Lee HS. Researchers have also found that the ethanol extracts of Poria cocos possess reverse-MDR ability, so Poria cocos was chosen as a Chinese herb here which is rich in triterpenoids. Many cancer-related genes were significantly up and down-regulated upon PA treatment. (A) PANC-1 and (B) MIA PaCa-2 cells were treated with or without PA (30 μM) in presence of TUDCA (200 μM) for 24 h. Apoptosis was detected by Cell Death Detection ELISA and expressed relative to vehicle-treated cells (set equal to 1). 1 The cDNA (100 ng per sample) was subjected to qPCR analysis in triplicate. This salt may also be used for purposes not listed in this medication guide. What's in Poria Cocos fungus? We observed that apoptosis induced by PA in chemotherapy resistant pancreatic cancer cells was not cell specific, as assessed in different gemcitabine-resistant pancreatic cancer cells PANC-1 and MIA PaCa-2 by detecting the presence of nuclear DNA fragmentation and PARP cleavage activation. Lost of olive oil, garlic, and cruciferous veggies fight canter, broccoli, Brussels sprouts ect. Bortezomib sensitizes pancreatic cancer cells to endoplasmic reticulum stress-mediated apoptosis, Chemical constituents and pharmacological properties of Poria cocos. Methods . Poria cocos (Polyporaceae) is a saprophytic fungus that grows in diverse species of Pinus. According to a study conducted by Indiana University’s Cancer Research Laboratory at Methodist Research Institute, in Indianapolis, a traditional Asian remedy made from the pine-bearing Poria cocos mushroom blocked the MMP gene, which is linked to the development of pancreatic cancer. So it’s not at all far-fetched that a mushroom might eventually prove to play a pivotal role in curing deadly pancreatic cancer. We are experimenting with display styles that make it easier to read articles in PMC. Analyzed the data: SC KS JNM GES DS. Nuclear factor-kappaB p65/relA silencing induces apoptosis and increases gemcitabine effectiveness in a subset of pancreatic cancer cells, Clinical cancer research: an official journal of the American Association for Cancer Research. Because of extrinsic factors (e.g. *P<0.050 was considered to be significant when compared to control (n = 8–10) by Student t-test. They also proved that GRP78 is downregulated by triptolide, which leading to apoptotic cell death of MIA PaCa-2 cells [60]. The MicroArray data are available at NCBI accesion number GSE64111.

Untransformed RMA signals were used for fold change calculations. Those are familiar names of people who have died from pancreatic cancer. Poria is widely used in Asia, and approximately 10% of medicinal preparations in the 2000 Pharmacopoeia of the People's Republic of China contain poria (fu-ling). Despite the findings, there is no evidence that injecting P. cocos into a live tumor has any cytotoxic effect or that taking the extract by mouth can either prevent or treat cancer. These results support our hypothesis that ER stress was involved in the regulation of PA mediated apoptosis in pancreatic cancer cells. New directions in ER stress-induced cell death, Apoptosis: an international journal on programmed cell death, Protein translation and folding are coupled by an endoplasmic-reticulum-resident kinase, The SERCA pump as a therapeutic target: making a "smart bomb" for prostate cancer. Tauroursodeoxycholic acid (TUDCA) was purchased from Calbiochem (Darmstadt, Germany). The 3’IVT express kit from Affymetrix (Affymetrix, Santa Clara, CA) was used to label the samples. The Center for Medical Genomics at Indiana University School of Medicine received total RNA and carried out all the steps of processing the RNA, hybridization to the Affymetrix Human PrimeView GeneChips, washing, scanning and initial analysis. The average tumor volume of mice in control group was approximately 448 mm3 comparing with about 112 mm3 in 25 mg kg-1 or 89 mm3 in 50 mg kg-1 PA treatment group, which was nearly 75% or 80% inhibition, respectively (Fig ​(Fig4A4A and ​and4B4B). But scientists are already working on the next phase of research to determine exactly how the mushroom extract turns down the MMP-7 gene…and whether the extract has the same effects in real life as it does in the lab.

Whole protein extracts isolated from cells were prepared and western blot analysis with anti-phospho-eIF2α and anti-eIF2α antibodies were performed as described in Materials and methods. Our results show that TUDCA treatment blocked the enormous increase in the expression of c-PARP associated with PA (Fig 3C–3F). *P<0.050 was considered to be significant when compared to control (n = 3) by Student t-test. In addition, based on standard toxicology studies including body weight measurements, organ pathology and liver enzyme profile analysis, we confirmed that 25 mg kg-1 of PA treatment is not toxic in vivo. 2)Cheng S. et al., Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7. Systematic screening and characterization of the major bioactive components of Poria cocos and their metabolites in rats by LC-ESI-MS(n). Several test-tube studies have suggested that Poria mushroom may have anti-tumor properties that may help fight or prevent certain types of cancer, including pancreatic cancer and breast cancer. This study was supported by research grants from China Scholarship Council and EcoNugenics, Inc., Santa Rosa, CA, USA. Interestingly, PA only slightly affects the proliferation of normal pancreatic duct epithelial cells and effective dose of PA is not toxic in vivo, which is particularly important in tumor-selective therapy. high glucose metabolic rate) in the tumor microenvironment, cancer cells exhibit higher levels of ER stress compared to normal cells [64]. A clinicopathologic study of 28 cases, The American journal of surgical pathology. 4) Cancer Several studies on human cells indicate that poria may possess anti-tumor properties and could help fight some forms of cancer (including pancreatic cancer and breast cancer). Regulated translation initiation controls stress-induced gene expression in mammalian cells, Cellular response to endoplasmic reticulum stress: a matter of life or death. Something went wrong while submitting the form. Importantly, the mushroom extract had minimal effect on the normal pancreatic cells. β-actin was used as loading control. Researchers believe Poria cocos has potential in the treatment of pancreatic cancer. Exploration, normalization, and summaries of high density oligonucleotide array probe level data. Control, 25 mg PA kg-1 and 50 mg PA kg-1 were compared by ANOVA with Bonferroni correction for the significant level. Boelens J, Lust S, Offner F, Bracke ME, Vanhoecke BW. In addition, the induction of nuclear DNA fragmentation associated with PA was rescued by TUDCA treatment (Fig ​(Fig3A3A and ​and3B).3B). Effect of TUDCA on PA induced expressions of ATF4 and CHOP in (C) PANC-1 and (D) MIA PaCa-2 cells were shown as well. Interestingly, a significant increase in the expression of ER stress related proteins, such as ATF4 and CHOP, were shown in the tumors of PA treated mice as compared to controls (Fig 8C–8E). Departments of Medicine, School of Medicine, Indiana University, Indianapolis, Indiana, United States of America. In order to investigate the changes in the protein levels which are more convincing, tumors from control and 25 mg kg-1 of PA treated mice were lysed and analyzed by western blot. The q-value program from Storey and Tibshirani was used to calculate false discovery rates. Zhao YY, Feng YL, Du X, Xi ZH, Cheng XL, Wei F. Diuretic activity of the ethanol and aqueous extracts of the surface layer of Poria cocos in rat, Inhibition of breast cancer metastasis via PITPNM3 by pachymic acid, Asian Pacific journal of cancer prevention: APJCP, Pachymic acid impairs breast cancer cell invasion by suppressing nuclear factor-kappaB-dependent matrix metalloproteinase-9 expression. Pulverized sclerotium of P. cocos (2.0 kg) was extracted three times with 95% ethanol (10 l) under reflux for 3h at room temperature. Liver, kidney, spleen, lung and heart tissues were stained with H&E. When tumors became palpable after 1–3 weeks (40–60 mm3), animals were randomly assigned into three groups (n = 15) and received intraperitoneal (i.p.) Toxicity of PA was evaluated in the 6 weeks old female nude mice (Harlan, Indianapolis, IN). β-actin was used as loading control. As shown in Fig 3C and Fig 3D, TUDCA treatment blocked the induction of ATF4 and CHOP in both PANC-1 and MIA PaCa-2 cells. To overcome the effects of ER stress, a series of adaptive and protective strategies have evolved, including two highly conserved systems—the heat shock response (HSR) and the unfolded protein response (UPR) [10]. Animal experiments were performed as described in Fig 4. All data have been deposited in NCBI's Gene Expression Omnibus and are accessible through GEO Series accession number {"type":"entrez-geo","attrs":{"text":"GSE64111","term_id":"64111"}}GSE64111.

You probably know someone who has succumbed to it as well, given that it is the fourth-leading cause of cancer-related deaths in the US. Oops! Among these genes, a relatively large number of genes related to stress response, especially ER stress, were identified by searching literature. Fold change P < 1E-05. As a member of the ATF/CREB subfamily of the basic-region leucine zipper (bZIP) family [50], ATF3 works directly or indirectly as a transcriptional activator of genes targeted by the eIF2 kinase stress pathway in UPR, and phosphorylation of eIF2α by PERK is an early event in a coordinate gene expression response to ER stress [14, 51–53]. *P<0.050 was considered to be significant when compared to control (n = 3) by Student t-test. Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7 *P < 0.050 for 50 mg kg-1 PA vs. control by ANOVA.
