[Ab] Resumo:Lung cancer causes huge mortality to population, and pharmaceutical companies require new drugs as an alternative either synthetic or natural targeting lung cancer. The conventional therapies cause side effects, and therefore, natural products are used as a therapeutic candidate in lung cancer. Chemical diversity among natural products highlights the impact of evolution and survival of fittest. One such neglected natural product is Ganoderma lucidum used for promoting health and longevity for a longer time. The major bioconstituents of G. lucidum are mainly terpenes, polysaccharides, and proteins, which were explored for various activities ranging from apoptosis to autophagy. The bioconstituents of G. lucidum activate plasma membrane receptors and initiate various downstream signaling leading to nuclear factor-κB, phosphoinositide 3-kinase, Akt, and mammalian target of rapamycin in cancer. The bioconstituents regulate the expression of various genes involved in cell cycle, immune response, apoptosis, and autophagy in lung cancer. This review highlights the inextricable role of G. lucidum and its bioconstituents in lung cancer signaling for the first time.

[Ab] Resumo:Seven new compounds including four lanostane triterpenoids, lucidenic acids Q-S (1-3) and methyl ganoderate P (4), and three triterpene-farnesyl hydroquinone conjugates, ganolucinins A-C (5-7), one new natural product ganomycin J (8), and 73 known compounds (9-81) were isolated from fruiting bodies of Ganoderma lucidum. The structures of the compounds 1-8 were determined by spectroscopic methods. Bioactivities of compounds isolated were assayed against HMG-CoA reductase, aldose reductase, α-glucosidase, and PTP1B. Ganolucidic acid η (39), ganoderenic acid K (44), ganomycin J (8), and ganomycin B (61) showed strong inhibitory activity against HMG-CoA reductase with IC of 29.8, 16.5, 30.3 and 14.3µM, respectively. Lucidumol A (67) had relatively good effect against aldose reductase with IC of 19.1µM. Farnesyl hydroquinones ganomycin J (8), ganomycin B (61), ganomycin I (62), and triterpene-farnesyl hydroquinone conjugates ganoleuconin M (76) and ganoleuconin O (79) possessed good inhibitory activity against α-glucosidase with IC in the range of 7.8 to 21.5µM. This work provides chemical and biological evidence for the usage of extracts of G. lucidum as herbal medicine and food supplements for the control of hyperglycemic and hyperlipidemic symptoms.

[Ab] Resumo:The medical mushroom Ganoderma lucidum (Reishi), a traditional Chinese medicine, has exhibited a promising anti-cancer effect. However, the molecular mechanism of its action on cancer cells remains unclear. Aberrant activation of Wnt/ß-catenin signaling pathway is the cause of many types of cancer, including breast cancer. Here we investigated the effect of Reishi on Wnt/ß-catenin signaling pathway and elucidated the molecular mechanism of its function in inhibiting breast cancer cells. We found that Reishi blocked Wnt/ß-catenin signaling through inhibiting the phosphorylation of Wnt co-receptor LRP6. In human (MDA-MB-231) and mouse (4T1) breast cancer cell lines, Reishi significantly decreased the phosphorylation of LRP6 and suppressed Wnt3a-activated Wnt target gene Axin2 expression. Administration of Reishi inhibited Wnt-induced hyper-proliferation of breast cancer cells and MDA-MB-231 cell migration. Our results provide evidence that Reishi suppresses breast cancer cell growth and migration through inhibiting Wnt/ß-catenin signaling, indicating that Reishi may be a potential natural inhibitor for breast cancer.

[Ti] Título:Anticarcinogenic effects of water extract of sporoderm-broken spores of Ganoderma lucidum on colorectal cancer in vitro and in vivo.

[Ab] Resumo:Ganoderma lucidum (G. lucidum) polysaccharides (GLPs) have been used as traditional Chinese medicine for cancer prevention for many years. However, the mechanism by which GLP exerts its chemopreventive activities remains elusive. In addition, it is unclear whether sporoderm-broken spores of G. lucidum water extract (BSGLWE), which contains mainly GLPs, has anticancer effects on colorectal cancer. The present study investigated the anticancer effects and potential mechanisms of BSGLWE on colorectal cancer in vivo and in vitro. Our results showed that BSGLWE significantly inhibited colorectal cancer HCT116 cell viability in a time- and dose-dependent manner. Flow cytometry analysis indicated that BSGLWE disrupted cell cycle progression at G2/M phase via downregulation of cyclin B1 and cyclin A2, and upregulation of P21 at mRNA levels. Moreover, BSGLWE induced apoptosis by decreasing Bcl-2 and survivin at mRNA levels, and reduced Bcl-2, PARP, pro-caspase-3 and pro-caspase-9 at protein levels. Furthermore, BSGLWE suppressed tumor growth in vivo by regulating the expression of genes and proteins associated with cell cycle and apoptosis, which was further confirmed by a reduction of Ki67, PCNA, and Bcl-2 expression as determined by immunohistochemistry staining. NSAID activated gene-1 (NAG-1), a pro-apoptotic gene, was significantly upregulated in vivo and in vitro upon BSGLWE treatment at both mRNA and protein levels. In addition, the relative amounts of secreted NAG-1 in cell culture medium or serum of nude mice were all upregulated upon BSGLWE treatments, suggesting a role of NAG-1 in BSGLWE-induced anticolorectal cancer activity. This is the first study to show that BSGLWE inhibits colorectal cancer carcinogenesis through regulating genes responsible for cell proliferation, cell cycle and apoptosis cascades. These findings indicate that BSGLWE possesses chemopreventive potential in colorectal cancer which may serve as a promising anticancer agent for clinical applications.

[Ab] Resumo:We demonstrate herein that salicylic acid (SA) can enhance ganoderic acid (GA) accumulation in the lingzhi or reishi medicinal mushroom Ganoderma lucidum. Following treatment with different concentrations of SA, the GA content was increased 22.72% to 43.04% compared with the control group. When the fungi were treated with 200 µmol/L SA at different times, the GA content was improved 10.21% to 35.24% compared with the control group. By choosing the optimum point based on response surface methodology, the GA content could be increased up to 229.03 µg/100 mg, which was improved 66.38% compared with the control group. When the fungi were treated with 200 µmol/L SA, the transcription levels of key genes in the GA biosynthesis pathway-squalene (SQ) synthase (sqs), lanosterol (Lano; osc), and hydroxy-3-methylglutaryl-coenzyme A reductase (hmgr)-were improved 119.6-, 3.2-, and 4.2-fold, respectively. In addition, following treatment with 100 µmol/L SA, the levels of Lano and SQ, which are intermediate metabolites of GA biosynthesis, were increased 2.8- and 1.4-fold, respectively. These results indicate that SA can regulate the expression of genes related to GA biosynthesis and increases the metabolic levels of Lano and SQ, thereby resulting in the accumulation of GA.

[Ab] Resumo:Among the most important traditional medicinal fungi, has been used as a therapeutic agent for the treatment of numerous diseases, including cancer, in Oriental countries. The aim of this study is to investigate the anti-inflammatory, anticancer and anti-metastatic activities of extracts in melanoma and triple-negative breast cancer cells. extracts were prepared by using common organic solvents; MDA-MB 231 and B16-F10 cell lines were adopted as cellular models for triple-negative breast cancer and melanoma and characterized for cell viability, wound-healing assay and measurement of cytokines secreted by cancer cells under pro-inflammatory conditions (incubation with lipopolysaccharide, LPS) and pretreatment with extract at different concentrations. Our study demonstrates, for the first time, how extracts can significantly inhibit the release of IL-8, IL-6, MMP-2 and MMP-9 in cancer cells under pro-inflammatory condition. Interestingly, extracts significantly also decrease the viability of both cancer cells in a time- and concentration-dependent manner, with abilities to reduce cell migration over time, which is correlated with a lower release of matrix metalloproteases. Taken together, these results indicate the possible use of extract for the therapeutic management of melanoma and human triple-negative breast cancer.

[Ti] Título:Expression and characteristics of manganese peroxidase from Ganoderma lucidum in Pichia pastoris and its application in the degradation of four dyes and phenol.

[Ab] Resumo:BACKGROUND: Manganese peroxidase (MnP) of white rot basidiomycetes, an extracellular heme enzyme, is part of a peroxidase superfamily that is capable of degrading the different phenolic compounds. Ganoderma, a white rot basidiomycete widely distributed worldwide, could secrete lignin-modifying enzymes (LME), including laccase (Lac), lignin peroxidases (LiP) and MnP. RESULTS: After the selection of a G. lucidum strain from five Ganoderma strains, the 1092 bp full-length cDNA of the MnP gene, designated as G. lucidum MnP (GluMnP1), was cloned from the selected strain. We subsequently constructed an eukaryotic expression vector, pAO815:: GlMnP, and transferred it into Pichia pastoris SMD116. Recombinant GluMnP1 (rGluMnP1) was with a yield of 126 mg/L and a molecular weight of approximately 37.72 kDa and a specific enzyme activity of 524.61 U/L. The rGluMnP1 could be capable of the decolorization of four types of dyes and the degradation of phenol. Phenol and its principal degradation products including hydroquinone, pyrocatechol, resorcinol, benzoquinone, were detected successfully in the experiments. CONCLUSIONS: The rGluMnP1 could be effectively expressed in Pichia pastoris and with a higher oxidation activity. We infer that, in the initial stages of the reaction, the catechol-mediated cycle should be the principal route of enzymatic degradation of phenol and its oxidation products. This study highlights the potential industrial applications associated with the production of MnP by genetic engineering methods, and the application of industrial wastewater treatment.

[La] Idioma:eng
[Ab] Resumo:Solid-state fermentation was evaluated at the pilot-scale for the bioconversion and valorization of rice husks and straw (RSH), or sunflower seed hulls (SSH), into medicinal mushrooms and crude extracts, with laccase activity. The average mushroom yield was 56kg dry weight per ton of agro-residues. Laccase activity in crude aqueous extracts showed its maximum value of 10,927Ukg in RSH (day 10, Exudate phase) and 16,442Ukg in SSH (day 5, Full colonization phase), the activity at the Residual substrate phase being 511Ukg in RSH and 803Ukg in SSH, respectively. Crude extracts obtained with various protocols revealed differences in the extraction yields. Lyophilization followed by storage at 4°C allowed the preservation of laccase activity for more than one month. It is proposed that standard mushroom farms could increase their profits by obtaining laccase as a byproduct during the gaps in mycelium running.

[Ab] Resumo:Ganoderma lucidum has become a potential model system for evaluating how environmental factors regulate the secondary metabolism of basidiomycetes. Heat stress (HS) is one of the most important environmental factors. It was previously reported that HS could induce the biosynthesis of ganoderic acids (GA). In this study, we found that HS increased GA biosynthesis and also significantly increased cell membrane fluidity. Furthermore, our results showed that addition of the membrane rigidifier dimethylsulfoxide (DMSO) could revert the increased GA biosynthesis elicited by HS. These results indicate that an increase in membrane fluidity is associated with HS-induced GA biosynthesis. Further evidence showed that the GA content was decreased in D9des-silenced strains and could be reverted to WT levels by addition of the membrane fluidizer benzyl alcohol (BA). In contrast, GA content was increased in D9des-overexpression strains and could be reverted to WT levels by the addition of DMSO. Furthermore, both membrane fluidity and GA biosynthesis induced by HS could be reverted by DMSO in WT and D9des-silenced strains. To the best of our knowledge, this is the first report demonstrating that membrane fluidity is involved in the regulation of heat stress induced secondary metabolism in filamentous fungi.
