Pachymic acid also influenced expression of MMP-7. Your submission has been received! 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. Klimstra DS, Heffess CS, Oertel JE, Rosai J. Acinar cell carcinoma of the pancreas. Zieger from Cryobiology Laboratory, Methodist Research Institute, Indiana University Health. Target molecules XBP-1s, ATF4, phospho-eIF2α, HSPA and CHOP are in red. Consistent with gene expression array data obtained at the mRNA level after 24 h treatment, induction of ER stress response in PANC-1 and MIA PaCa-2 cells were detected by western blot analysis of Hsp70 and CHOP. *P<0.050 was considered to be significant when compared to control (n = 3) by Student t-test. Source: Cheng S, Eliaz I, Lin J, Sliva D. Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7. To confirm our observation in vivo, we employed a xenograft model of chemotherapy resistant pancreatic cancer. Lee SM, Lee YJ, Yoon JJ, Kang DG, Lee HS. Detailed information related to Poria Cocos's uses, side-effects, reviews, … 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. (A) Representative H&E staining in pancreatic tumors, (B) quantification of apoptotic bodies was determined as described in Materials and methods. 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]. The high mortality rates of pancreatic cancer, one of the most lethal cancers worldwide, are the result of inadequate tools for early diagnosis and few therapeutic options [1]. Analyzed the data: SC KS JNM GES DS. 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. 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. Zhu W, Li J, Wu S, Li S, Le L, Su X, et al. The q-value program from Storey and Tibshirani was used to calculate false discovery rates. 3 Five-micrometer sections were stained with H&E. A medical clinician, helped in determining doses to be tested, based on possible future clinical relevance and final editing of the manuscript and did not affect data collection and analysis, or decision to publish: IE. Suzuki T, Lu J, Zahed M, Kita K, Suzuki N. Reduction of GRP78 expression with siRNA activates unfolded protein response leading to apoptosis in HeLa cells. 1869-1874, 10.3892/ijo.2013.1902 Increasing translation of ATF4 results in the transcriptional activation of CHOP [57]. MIA PaCa-2 cells were treated with PA (0 and 30 μM) for 24 h in quadruplicates. However, based on in vitro cell-based and in vivo mouse xenograft results in our study, we concluded that PA induced apoptosis of pancreatic cancer cells through activating ER stress. Cause for hope: The potent drugs morphine, penicillin and paclitaxel (Taxol, which is used to treat lung, breast and ovarian cancers) were derived from poppy plants, mold and Pacific yew tree bark, respectively. A compound symmetric covariance structure was assumed and interaction between groups and time in the model is of primary interest. PARP is a 116-kDa nuclear poly (ADP-ribose) polymerase, which is involved in DNA repair in response to environmental stress and cleavage of PARP facilitates cell disassembly [39, 40]. 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. 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]. 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. Dosage of Poria Cocos … Previous work in our laboratory has shown that PA suppresses growth and invasiveness of pancreatic cancer cells through downregulation of MMP-7 [29]. PANC-1, MIA PaCa-2 cells were treated with PA (0–30 μM) for 10 min, 30 min or 24 h, respectively. 1. Gene expression profiling by microarray has been widely used in screening drug targets [48]. The Center for Medical Genomics is supported in part by the Indiana Genomics Initiative at Indiana University (INGEN, which is supported in part by the Lilly Endowment, Inc.). Targeting the endoplasmic reticulum-stress response as an anticancer strategy. Both tests had p = 0.004, showing that at day 34, the tumor volumes in each treatment group was significantly different from control. The slides were viewed under a Leica microscope (Leica Instruments, Melville, NY) and apoptosis in the viable tumor cell area was quantified by counting apoptotic bodies in four 20 x fields of view for n = 6–12 tumors per group by 2 independent observers. 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. Anti-CHOP, anti-phospho-eIF2α and anti-eIF2α antibodies were obtained from Cell Signaling Technology (Beverly, MA). Among these genes, a relatively large number of genes related to stress response, especially ER stress, were identified by searching literature. It is induced by ATF3 in response to prolonged ER stress and is the downstream component of ATF4 [54, 56]. Total RNA was isolated from tumors with RNeasy Mini Kit (Qiagen, Valencia, CA). 3, 3'-diindolylmethane and its derivatives induce apoptosis through ER stress-dependent upregulation of death receptor in pancreatic cancer cells [19]. Those are familiar names of people who have died from pancreatic cancer. HSR involves stimulation of factors and pathways, such as inducing the synthesis of molecular chaperones (e.g., Hsp70), to attenuate the burden of misfolded proteins [10, 12]. Data was analyzed by 2-way ANOVA using cell line and treatment as factors plus the interaction of cell line and treatment. Malo A, Kruger B, Seyhun E, Schafer C, Hoffmann RT, Goke B, et al.

Eye Health: Top Doc’s Integrated Approach, Face Value: Investing in Metals and Money. 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. In this paper, we investigated the anticancer effect of PA on human chemotherapy resistant pancreatic cancer. Conventional cancer treatments, such as inhibitors of mitosis or S phase, target all the proliferating cells, therefore cause many side effects [63]. Both systems act as quality control processes to facilitate protein folding and suppress protein synthesis [10, 11]. Animal experiments were performed as described in Fig 4. Media came from ATCC. Pachymic acid (PA) is a purified triterpene extracted from medicinal fungus Poria cocos. However, the effect of PA against pancreatic cancer remains to be evaluated and the mechanism is not clear. Moreover, PA elevated the expression of ATF3. (A) PANC-1 and (B) MIA PaCa-2 cells were treated with PA (0–30 μM) for 24 h, respectively. Three independent experiments were done for the western blot studies and quantitative data composed of all the experiments in E) PANC-1 and F) MIA PaCa-2 cells with statistical analysis were shown below the representative blot image. PA triggered apoptosis in gemcitabine-resistant pancreatic cancer cells PANC-1 and MIA PaCa-2. Poria cocos is a medicinal fungus in the Polyporaceae family that grows in pine trees and its sclerotium is widely used in traditional Asian medicine for its sedative, diuretic, digestive and tonic effects [21–23]. Regulated translation initiation controls stress-induced gene expression in mammalian cells, Cellular response to endoplasmic reticulum stress: a matter of life or death.

This study was supported by research grants from China Scholarship Council and EcoNugenics, Inc., Santa Rosa, CA, USA. already built in. Supplements, FBS and HS were obtained from Gibco BRL (Grand Island, NY). Although PA inhibits growth of chemotherapy resistant pancreatic tumors in vivo, its possible toxicity must be tested comprehensively. Representative blots from three experiments were shown and quantitative data composed of all the experiments in C), G) PANC-1 and D), H) MIA PaCa-2 cells with statistical analysis were below the representative blot image. Departments of Pathology, School of Medicine, Indiana University, Indianapolis, Indiana, United States of America. Moreover, ER stress inhibitor tauroursodeoxycholic acid (TUDCA) blocked PA induced apoptosis. A 2018 study in the journal Cells reported that the P. cocos extract exhibited cytotoxicity (cell-killing abilities) to four human lung cancer cell lines. Pachymic acid (PA) is a purified triterpene extracted from medicinal fungus Poria cocos. These results strongly support that PA activates ER stress in pancreatic cancer cells. Anti-Hsp70 was obtained from Enzo Life Sciences (Farmingdale, NY). 22 June, 2017. Many cancer-related genes were significantly up and down-regulated upon PA treatment. S. Cheng, et al.Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7 Int. Apoptosis was confirmed in C) PANC-1 and D) MIA PaCa-2 cells treated with same concentrations of PA in presence of TUDCA (200 μM) for 24 h. Representative blots show expression of PARP cleavage (c-PARP) and β-actin was used as loading control. PA triggered apoptosis in gemcitabine-resistant pancreatic cancer cells PANC-1 and MIA PaCa-2.

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. *P < 0.050 for 50 mg kg-1 PA vs. control by ANOVA. 187 0. Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7 In fact, many researchers have shown that the extract from mushrooms, especially medical mushrooms, has the ability to inhibit the development of pancreatic cancer cells. Abdelrahim M, Newman K, Vanderlaag K, Samudio I, Safe S. 3,3'-diindolylmethane (DIM) and its derivatives induce apoptosis in pancreatic cancer cells through endoplasmic reticulum stress-dependent upregulation of DR5. Induced ER stress was confirmed by increasing expression of XBP-1s, ATF4, Hsp70, CHOP and phospho-eIF2α. Ling H, Jia X, Zhang Y, Gapter LA, Lim YS, Agarwal R, et al. In the present investigation, 191 genes were significantly upregulated in MIA PaCa-2 cells after 30 μM PA treatment (fold change threshold = 1.50; ANOVA, Storey-Tibshirani false discovery rate correction, P < 1E-05) (S1 Table). found the overexpression of GRP78 in the human pancreatic cancer cell lines and tissue samples. Pancreatic Cancer. The MicroArray data are available at NCBI accesion number GSE64111. Animal experiments were conducted strictly in accordance with the protocol approved by the Animal Research Committee at the Methodist Hospital (protocol no. Because of extrinsic factors (e.g. Several test-tube studies have suggested that Poria mushroom may possess anti-tumor properties that could help fight or prevent certain forms of cancer, including pancreatic cancer and breast cancer. In addition, the phosphorylated form of eIF2α (p-eIF2α), a sensitive indicator of ER stress and key regulator of UPR [7, 41], was detectable after 10 min PA treatment (30 μM) in PANC-1 and MIA PaCa-2 cells (Fig ​(Fig2E2E and ​and2F).2F). Moreover, two transcription factors involved in UPR system, XBP1and ATF4, were significantly activated as well (Fig 2A–2D). Fold change P < 1E-05. The 3’IVT express kit from Affymetrix (Affymetrix, Santa Clara, CA) was used to label the samples. Inhibition of proliferation by omega-3 fatty acids in chemoresistant pancreatic cancer cells, Cytotoxic therapy for advanced pancreatic adenocarcinoma. Poria cocos F.A.Wolf) is a fungus in the family Polyporaceae.It is a wood-decay fungus but has a subterranean growth habit. Michael Landon, Luciano Pavarotti, Sally Ride, Jack Benny, Patrick Swayze. Total-RNA from each sample was isolated with RNeasy Mini Kit (Qiagen, Valencia, CA) according to the manufacturer’s protocol. The quantitative real-time polymerase chain reaction (qRT-PCR) was performed using ABI PRISM 7900HT Fast Real-Time PCR System (Applied Biosystems, Foster City, CA) according to the manufacturer's instructions. The ePub format is best viewed in the iBooks reader. Studies have shown this mushrooms supports against: Fluid Retention (this mushroom is a diuretic and the triterpenes support urine output), Cancer (Skin Tumors, Melanoma/Skin Cancer, Pancreatic Cancer), Inflammation, and Spleen Deficiency. Sekiya N, Goto H, Shimada Y, Endo Y, Sakakibara I, Terasawa K. Inhibitory effects of triterpenes isolated from Hoelen on free radical-induced lysis of red blood cells. In order to prove our hypothesis, the amounts of apoptotic bodies in pancreatic tumor xenografts were quantified. Anti-XBP-1s from BioLegend (San Diego, CA), anti-ATF6 and anti-ATF4 from Abcam (Cambridge, MA) were kindly provided by Dr. Michael A.J. Apoptosis is characterized by marked changes in cell morphology, including nuclear breakdown, chromatin condensation, and appearance of membrane-associated apoptotic bodies [46]. Moreover, PA only slightly affects the growth of normal pancreatic duct epithelial cells HPDE-6 and also significantly suppresses invasive behavior of pancreatic cancer cells by inhibiting expression of MMP-7 [29]. To further emphasize the difference between groups, t-test was used to compare the mean tumor volumes of treatment groups to control at day 34. The graphical data represent mean +/- SD. A study published in the June issue of the International Journal of Oncology found that Poria Triterpine Extract (PTE), a mixture of triterpines from Poria cocos, a medicinal mushroom used in traditional Asian medicine, suppress the proliferation of human pancreatic cancer cell lines. (A) PANC-1 and (B) MIA PaCa-2 cells were treated with PA (0–30 μM) for 24 h. Apoptosis was detected by Cell Death Detection ELISA and expressed relative to vehicle-treated cells (set equal to 1). Researchers believe Poria cocos has potential in the treatment of pancreatic cancer. They also proved that GRP78 is downregulated by triptolide, which leading to apoptotic cell death of MIA PaCa-2 cells [60]. Pancreatic cancer has the lowest survival rate among all cancers. Yang Y, Li C, Xiang X, Dai Z, Chang J, Zhang M, et al. 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. Animal experiments were performed as described in Fig 4. The graphical data represent mean +/- SD. The studies reported here for the first time indicating that PA is a potent anticancer agent against chemotherapy resistant pancreatic cancer in vitro and in vivo, and highlight the importance of ER as a target for the treatment of pancreatic cancer. However, 50 mg kg-1 of PA treated mice showed several signs of discomfort and impaired movement comparing with control and 25 mg kg-1 of PA treated mice. PA was purchased from Shinning-biotech (Chengdu, Sichuan, China) and dissolved in DMSO at a concentration of 50 mM then stored at -20°C. However, a severe and prolonged ER stress during exposure to PA leads to the induction of pro-apoptotic transcription factor CHOP/GADD153. 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). So it’s heartening to learn that a traditional Asian remedy made from mushrooms may hold the key to winning the battle against this dreaded disease, according to a new laboratory study. also reported that increased expression of ATF3 occurs early in response to stress through a mechanism requiring the related bZIP transcriptional regulator activating transcription factor-4 (ATF4) [54], which is in accordance with our data of western blot analysis in vitro and in vivo. Usually dissolved in orane juice becaus of taste. 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. Taken together, growth inhibition and induction of apoptosis by PA in gemcitabine-resistant pancreatic cancer cells were associated with ER stress activation both in vitro and in vivo. View abstract.

Review. ac id, M M P-7. Gemcitabine, a cytotoxic nucleoside analogue, is the current clinical standard of care for advanced pancreatic cancer but has a response rate of less than 20% [2]. It was reported that pancreatic cancer cell lines PANC-1 and MIA PaCa-2 were resistant to gemcitabine treatment [35–37]. Poria cocos is a medicinal mushroom that is widely used in traditional Asian medicine. Hering J, Garrean S, Dekoj TR, Razzak A, Saied A, Trevino J, et al. 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). RNA quality was monitored and quantified using the Qubit 2.0 Fluorometer (Invitrogen, Carlsbad, CA). β-actin was used as loading control. 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. Fu Ling(concentrated Extract Powder)(poria Cocos Fungus. 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. 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. For instance, the mushroom extract seemed to silence one particular gene, MMP-7, that is overactive in pancreatic cancer cells. Here, we found both in vitro and in vivo evidence for the up-regulation of ATF4-dependent protein CHOP following PA treatment in chemotherapy resistant pancreatic cancer cells, which is closely associated with the progression of apoptosis.
