Abstract
In this study, a previously unknown fungal immunomodulatory protein (FIP), here called FIP-ppl, was identified from the basidiomycete fungus Postia placenta by searching its genome sequence database using known FIPs as baits, which was the first basidiomycete FIP to be identified outside the order of edible macro fungi. The gene FIP-ppl was synthesized and expressed in Escherichia coli to produce a glutathione S-transferase (GST) fusion protein. The fusion protein was purified on a GST affinity column and the protein tag was removed using in situ thrombin cleavage. The purified recombinant protein (rFIP-ppl) displayed hemagglutination activity toward rabbit red blood cells but not against human red blood cells. RFIP-ppl stimulated mouse splenocyte cell proliferation and enhanced interleukin-2 (IL-2) release. Antitumor assays indicated that rFIP-ppl had significant cell proliferation inhibitory activity and apoptotic effects in human tumor cells with more pronounced inhibiting proliferation and inducing apoptotic effects on gastric tumor cells (MGC823) than against hepatoma (HepG2) cells. This study confirms an alternative means of identifying, producing, and isolating new FIPs. It may provide convenient access to FIP-ppl with potential human therapeutic applications.

Abstract
The aim of this study was to conduct a molecular and biochemical characterization and to compare the antioxidant and antiproliferative activities of four Ganoderma isolates belonging to Ganoderma lucidum (Gl-4, Gl-5) and Ganoderma resinaceum (F-1, F-2) species. The molecular identification was performed by ITS and IGS sequence analyses and the biochemical characterization by enzymatic and proteomic approaches. The antioxidant activity of the ethanolic extracts was compared by three different methods and their flavonoid contents were also analyzed by high-performance liquid chromatography. The antiproliferative effect on U937 cells was determined by MTT assay. The studied mycelia differ both in the enzymatic activities and protein content. The highest content in total phenol and the highest antioxidant activity for DPPH free radical scavenging and chelating activity on Fe(2+) were observed with the Gl-4 isolate of G. lucidum. The presence of quercetin, rutin, myricetin, and morin as major flavonoids with effective antioxidant activity was detected. The ethanolic extracts from mycelia of G. lucidum isolates possess a substantial antiproliferative activity against U937 cells in contrast to G. resinaceum in which the antiproliferative effects were insignificant. This study provides a comparison between G. lucidum and G. resinaceum mycelial strains, and shows that G. resinaceum could be utilized to obtain several bioactive compounds.

Abstract
Mushrooms have been consumed since earliest history; ancient Greeks believed that mushrooms provided strength for warriors in battle, and the Romans perceived them as the “Food of the Gods.” For centuries, the Chinese culture has treasured mushrooms as a health food, an “elixir of life.” They have been part of the human culture for thousands of years and have considerable interest in the most important civilizations in history because of their sensory characteristics; they have been recognized for their attractive culinary attributes. Nowadays, mushrooms are popular valuable foods because they are low in calories, carbohydrates, fat, and sodium: also, they are cholesterol-free. Besides, mushrooms provide important nutrients, including selenium, potassium, riboflavin, niacin, vitamin D, proteins, and fiber. All together with a long history as food source, mushrooms are important for their healing capacities and properties in traditional medicine. It has reported beneficial effects for health and treatment of some diseases. Many nutraceutical properties are described in mushrooms, such as prevention or treatment of Parkinson, Alzheimer, hypertension, and high risk of stroke. They are also utilized to reduce the likelihood of cancer invasion and metastasis due to antitumoral attributes. Mushrooms act as antibacterial, immune system enhancer and cholesterol lowering agents; additionally, they are important sources of bioactive compounds. As a result of these properties, some mushroom extracts are used to promote human health and are found as dietary supplements.

Abstract
To our best knowledge, all of the fungal immunomodulatory proteins (FIPs) have been successfully extracted and identified in Basidomycetes, with only the exception of FIP from ascomycete Nectria haematococca (FIP-nha) discovered through homology alignment most recently. In this work, a gene encoding FIP-nha was synthesized and recombinantly expressed in an Escherichia coli expression system. SDS-PAGE and MALDI-MS analyses of recombinant FIP-nha (rFIP-nha) indicated that the gene was successfully expressed. The yield of the bioactive FIP-nha protein was 42.7 mg/L. In vitro assays of biological activity indicated that the rFIP-nha caused hemagglutination of human and rabbit red blood cells, significantly stimulated mouse spleen lymphocyte proliferation, and enhanced expression of interleukin-2 (IL-2) released from mouse splenocytes, revealing a strong antitumor effect against HL60, HepG2 and MGC823. Through this work, we constructed a rapid and efficient method of FIP production, and suggested that FIP-nha is a valuable candidate for use in future medical care and pharmaceutical products.

Abstract
Two Ganoderma species, G. lucidum and G. sinense, are listed as Lingzhi in Chinese Pharmacopoeia and they are considered to have the same therapeutic effects. Polysaccharides were the main immunomodulatory and anticancer components in Ganoderma. In this study, the chemical characters and the effects of polysaccharides from G. lucidum (GLPS) and G. sinense (GSPS) on macrophage functions were investigated and compared. Chemical studies showed that GLPS and GSPS were different, displaying various molecular weight distribution and ratio of monosaccharide components. In vitro pharmacological studies showed that both GLPS and GSPS had potent effects on macrophage functions, such as promoting macrophage phagocytosis, increasing their release of nitric oxide and cytokines interleukin (IL)-1α, IL-6, IL-10, and tumor necrosis factor-α. Generally, GLPS was more powerful than GSPS. This study is helpful to elucidate the active components and pharmacological variation between the 2 Ganoderma species. The structure-activity relationship of polysaccharides from Ganoderma needs further study.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ganoderma lucidum (W. Curt.:Fr.) P. Karst. has been used for several thousand years in traditional medicine of the Far East for the treatment of a various diseases including: cancer, immunological disorders, hepatitis, arthritis, nephritis, bronchitis, asthma etc. Ganoderma species are natural sources of various antimicrobial, antioxidant and antitumor active compounds which can be alternative to commercial antibiotics, antimycotics, antioxidants and cytostatics. As the amount of wild Ganoderma lucidum basidiocarps is not sufficient, the aim of this study was to compare the bioactivity of basidiaocarps obtained on alternative substrate (wheat straw) with commercially cultivated ones. MATERIALS AND METHODS Antimicrobial potential of the tested Ganoderma lucidum extracts was studied by disc-diffusion and microdilution method. Cytotoxic effect of tested extracts on two cancer cell lines was determined by microculture tetrazolium test. DPPH scavenging ability, total phenols and flavonoids content were measured in order to determine the antioxidative potential of Ganoderma lucidum extracts. RESULTS Ganoderma lucidum BEOFB 434 extract was the most effective antibacterial agent, while commercial strain was the weakest. DPPH· scavenging activity of extracts of basidiocarps from alternative substrate was also significantly higher than that of commercially obtained basidiocarps. The extracts of Ganoderma lucidum BEOFB 431 exhibited the strongest cytotoxic activity significantly higher than those in commercial strain. CONCLUSION The study showed that fruiting bodies produced on one of the most accessible and cheapest crop residue, wheat straw, are better antimicrobial, antioxidant and cytotoxic agents than those obtained on conventional substrate, oak sawdust.

Abstract
FIP-fve is an immunomodulatory protein isolated from Flammulina velutipes that possesses anti-inflammatory and immunomodulatory activities. However, little is known about its anticancer effects. It is suppressed cell proliferation of A549 lung cancer cells on MTT assay following 48 h treatment of FIP-fve. FIP-fve treatment also resulted in cell cycle arrest but not apoptosis on flow cytometry. This immunomodulatory protein was observed to increase p53 expression, as well as the expression of its downstream gene p21, on Western blot. FIP-fve inhibited migration of A549 cells on wound healing assay and decreased filopodia fiber formation on labeling with Texas Red-X phalloidin. To confirm the effect of FIP-fve on the role of Rac1 in filopodia formation, we investigated the activity of Rac1 in A549 cells following FIP-fve treatment. FIP-fve inhibited EGF-induced activation of Rac1. We demonstrated that FIP-fve decreases RACGAP1 mRNA and protein levels on RT-PCR and Western blot. In addition, the reporter activity of RACGAP1 was reduced by FIP-fve on RacGAP1 promoter assay. Silencing of RacGAP1 decreased cell migration, and overexpression of RacGAP1 increased cell migration in A549 cells. In conclusion, FIP-fve inhibits lung cancer cell migration via RacGAP1 and suppresses the proliferation of A549 via p53 activation pathway.

Abstract
BACKGROUND AND PURPOSE Autophagic cell death is considered a self-destructive process that results from large amounts of autophagic flux. In our previous study, GMI, a recombinant fungal immunomodulatory protein cloned from Ganoderma microsporum, induced autophagic cell death in lung cancer cells. The aim of this study was to examine the role of autophagosome accumulation in GMI-mediated cell death. EXPERIMENTAL APPROACH Western blot analysis, flow cytometry and confocal microscopy were used to evaluate the effects of different treatments, including silencing of ATP6V0A1 by use of short hairpin RNAi, on GMI-mediated cell death, lung cancer cell viability and autophagosome accumulation in vitro. KEY RESULTS Lysosome inhibitors bafilomycin-A1 and chloroquine increased GMI-mediated autophagic cell death. GMI and bafilomycin-A1 co-treatment induced the accumulation of large amounts of autophagosomes, but did not significantly induce apoptosis. GMI elicited autophagy through the PKB (Akt)/mammalian target of rapamycin signalling pathway. Silencing of ATP6V0A1, one subunit of vesicular H(+)-ATPases (V-ATPases) that mediates lysosome acidification, spontaneously induced autophagosome accumulation, but did not affect lysosome acidity. GMI-mediated autophagosome accumulation and cytotoxicity was increased in shATP6V0A1 lung cancer cells. Furthermore, ATP6V0A1 silencing decreased autophagosome and lysosome fusion in GMI-treated CaLu-1/GFP-LC3 lung cancer cells. CONCLUSION AND IMPLICATIONS We demonstrated that autophagosome accumulation induces autophagic cell death in a GMI treatment model, and ATP6V0A1 plays an important role in mediating autophagosome-lysosome fusion. Our findings provide new insights into the mechanisms involved in the induction of autophagic cell death.

Abstract
A fungal immunomodulatory protein isolated from Flammulina velutipes (FIP-fve) has structural similarity to the variable region of the immunoglobulin heavy chain. In the present study, the recombinant bioactive FIP-fve protein with a His-tag in N-terminal of recombinant protein was expressed in transetta (DE3) at a high level under the optimized culturing conditions of 0.2 mM IPTG and 28 °C. The efficiency of the purification was improved with additional ultrasonication to the process of lysozyme lysis. The yield of the bioactive FIP-fve protein with 97.1% purity reached 29.1 mg/L with a large quantity for industrial applications. Enzyme-linked immunosorbent assay showed a maximum increase in interleukin-2 (IL-2) and gamma interferon (IFN-γ) for the mice serum group of 5 mg/kg body mass (p < 0.01) with three doses of His-FIP-fve. However, the production of IL-4 had no apparent difference compared to the control.

Abstract
With the exception of polysaccharides and triterpenes/triterpenoids compounds, fungal immunomodulatory protein (FIP), a small molecule protein, is also an important bioactive component with immune regulating activity. It plays a significant role in immunomodulating. The objective of this paper was to review the latest advances in various aspects of research on FIPs, including their basic components and structural character, characters of diversity, gene cloning and expression, and their biological function, etc. In addition, prospects of utilization value and the exploitation foreground of FIPs were also discussed. The review will provide a useful reference for further research, development, and utilizations of FIPs.

Abstract
Matrix metalloproteinase 9 (MMP-9) has been implicated in airway injury in chronic obstructive pulmonary disease (COPD), lung inflammation, and lung cancer and plays a major role in tumor necrosis factor-α (TNF-α)-stimulated tumor invasion and lung inflammation. MMP-9 activity is promoted by the pro-inflammatory cytokine TNF-α. GMI, cloned from Ganoderma microsporum and purified, is one of the recombinant fungal immunomodulatory proteins. To understand the molecular mechanisms involved in the suppression of TNF-α-mediated tumor invasion and inflammation, GMI modulation of this pathway was investigated in human alveolar epithelial A549 cells in this study. GMI exhibited an inhibitory effect on TNF-α-induced invasion, with GMI treatment and TNF-α exposure presenting the most anti-invasive properties on Boyden chamber assay. GMI reduced TNF-α-induced MMP-9 activities on gelatin zymography assay through inhibition of MMP-9 transcriptional activity. RT-PCR and MMP-9 promoter luciferase analysis revealed that GMI inhibits the transcription of MMP-9 mRNA. Moreover, in vitro and in vivo binding experiments, an electrophoretic mobility shift assay (EMSA), and chromatin immunoprecipitation assay (ChIP) demonstrated that GMI suppresses DNA binding of nuclear factor (NF)-κB transcription factors to MMP-9 promoter. Western blot analysis indicated that GMI blocks the phosphorylation and degradation of IκBα, which in turn leads to suppression of the phosphorylation and nuclear translocation of p65. Thus, overall, our results indicated that GMI mediates antitumor invasion and anti-inflammatory effects through modulation of NF-κB/MMP-9 pathways.
