Abstract
Ganoderma capense is a precious medicinal fungus in China. In this study, a novel fungal immunomodulatory protein gene, named as FIP-gca, was cloned from G. capense by homologous cloning. Sequencing analysis indicated that FIP-gca was composed of 336 bp, which encoded a polypeptide of 110 amino acids. Protein sequence blasting and phylogenetic analysis showed that FIP-gca shared homology with other Ganoderma FIPs. FIP-gca was effectively expressed in Pichia pastoris GS115 at an expression level of 166.8 mg/L and purified using HisTrap™ fast-flow prepack columns. The immunomodulation capacity of rFIP-gca was demonstrated by that rFIP-gca could obviously stimulate cell proliferation and increase IL-2 secretion of murine spleen lymphocytes. Besides, antitumor activity of rFIP-gca towards human stomach cancer AGS cell line was evaluated in vitro. Cell wound scratch assay proved that rFIP-gca could inhibit migration of AGS cells. And flow cytometry assay revealed that rFIP-gca could significantly induce apoptosis of AGS cells. rFIP-gca was able to induce 18.12% and 22.29% cell apoptosis at 0.3 μM and 0.6 μM, respectively. Conclusively, the novel FIP-gca gene from G. capense has been functionally expressed in Pichia and rFIP-gca exhibited ideal immunomodulation and anti-tumour activities, which implies its potential application and study in future.

Abstract
Proteins from edible mushrooms have a variety of biological activities. Here, thirteen precious edible mushrooms such as Ophiocordyceps sinensis, Ganoderma lucidum, and Morchella esculenta and nine common edible mushrooms such as Flammulina velutipes, Pleurotus ostreatus, and Pleurotus eryngii, etc., from which their proteins were extracted, their composition analyzed and their immunomodulatory activity assessed. Rare mushrooms are a species of edible mushrooms with higher edible value and medicinal value than common edible mushrooms. The results showed that all the different edible mushroom crude proteins increased the proliferation and phagocytosis of mouse macrophages, and we found that these edible mushroom proteins affected the secretion of reactive oxygen species and nitric oxide by mouse macrophages. Further studies on cytokines secreted by mouse macrophages showed a significant increase in pro-inflammatory cytokines, suggesting that edible mushroom proteins promote the polarisation of macrophages into classical M1-type macrophages, further demonstrating that edible mushroom proteins enhance immunity. It was also found that the immunomodulatory activity of the precious edible mushroom proteins was significantly higher than that of the common edible mushroom proteins. These results have important implications for the processing and product development of edible mushroom proteins.

Abstract
This work investigated the preparation, characterization, antioxidant, and anti-inflammation capacities of Flammulina velutipes polyphenols (FVP) and fermented FVP (FFVP). The results revealed that the new syringic acid, accounting for 22.22%, was obtained after fermentation (FFVP). FFVP exhibits higher antioxidant and anti-inflammation activities than FVP, enhancing cell viability and phagocytosis, inhibiting the secretion of NO and ROS, and reducing the inflammatory response of RAW264.7 cells. This study revealed that FFVP provides a theoretical reference for in-depth study of its regulatory mechanisms and further development of functional antioxidants that are applicable in the food and health industry.

Abstract
The global health emergency generated by coronavirus disease-2019 has prompted the search for immunomodulatory agents. There are many potential natural products for drug discovery and development to tackle this disease. One of these candidates is the Ganoderma lucidum fungal immunomodulatory protein (FIP-glu). In the present study, we clarify the influences of N-linked glycans on the improvement of anti-inflammatory activity and the potential mechanisms of action. Four proteins, including FIP-glu (WT) and its mutants N31S, T36N and N31S/T36N, were successfully expressed in P. pastoris, of which T36N and N31S/T36N were glycoproteins. After treatment with peptide-N-glycosidase F, the results of SDS-PAGE and Western blot showed that the glycan moiety was removed completely, indicating that the glycan moiety was N-linked. This was also demonstrated by UPLC-qTOF-MS. The cytotoxicity assay showed that N-linked glycans decreased the cytotoxicity of WT; while, the RT-qPCR assay showed that N-glycosylated WT regulated the mRNA expression of IL-6 and TGF-β1. The Western blot results showed that N-glycosylated WT reduced the phosphorylation level of p38 MAPK. In conclusion, our findings revealed a novel mechanism by which N-glycosylation of FIP-glu improved its anti-inflammatory activity through the regulation of the expression of inflammatory cytokines in RAW264.7 via inhibition of p38 MAPK phosphorylation. It was proved that N-glycosylation significantly improved the functional properties of FIP-glu, providing theoretical and technical support for expanding the application of FIPs in the food and pharmaceutical industries.

Appl Microbiol Biotechnol 2021; 105:2799-2813. [PMID: 33763709 DOI: 10.1007/s00253-021-11225-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 02/24/2021] [Accepted: 03/07/2021] [Indexed: 10/21/2022]
Abstract
Fungal immunomodulatory proteins (FIPs) are bioactive proteins with immunomodulatory properties. We previously reported the heterologous production in Escherichia coli of FIP-Lrh from Tiger milk mushroom (Lignosus rhinocerus) with potent cytotoxic effect on cancer cell lines. However, protein produced in E. coli lacks post-translational modifications and may be contaminated with lipopolysaccharide (LPS) endotoxin. Therefore, in this study, yFIP-Lrh produced in Pichia pastoris was functionally compared with eFIP-Lrh produced in E. coli. Expression construct of FIP-Lrh cDNA in pPICZα was generated, transformed into P. pastoris X-33 and Mut+ transformants were verified by colony PCR. Induction with 0.5% or 1% methanol resulted in a secreted 13.6 kDa yFIP-Lrh which was subsequently purified and verified using LCMS/MS analysis. Size exclusion chromatography confirmed eFIP-Lrh as a homodimer whereas the larger size of yFIP-Lrh may indicate post-translational modification despite negative for glycoproteins staining. At lower concentration (4-8 μg/mL), yFIP-Lrh induced significantly higher Th1 (IFN-γ, TNF-α) and Th2 (IL-6, IL-4, IL-5, IL-13) cytokines production in mice splenocytes, whereas 16 μg/mL eFIP-Lrh induced significantly higher pro-inflammatory cytokines (TNF-α, IL-6, IL-10), possibly due to higher residual LPS endotoxin (0.082 EU/mL) in eFIP-Lrh compared to negligible level in yFIP-Lrh (0.001 EU/mL). Furthermore, yFIP-Lrh showed higher cytotoxic effect on MCF-7 and HeLa cancer cells. Since both recombinant proteins of FIP-Lrh have the same peptide sequence, besides glycosylation, other post-translational modifications in yFIP-Lrh may account for its enhanced immunomodulatory and anti-proliferative activities. In conclusion, P. pastoris is preferred over E. coli for production of a functionally active yFIP-Lrh devoid of endotoxin contamination. KEY POINTS: • FIP-Lrh can induced production of Th1 and Th2 cytokines by mouse splenocytes. • Higher cytotoxic effect on cancer cells observed for yeast compared to E. coli produced FIP-Lrh. • P. pastoris allows production of an endotoxin-free and functionally active recombinant FIP-Lrh.

Abstract
Fungal immunomodulatory proteins (FIPs) are a group of proteins found in fungi, which are extensively studied for their immunomodulatory activity. Currently, more than 38 types of FIPs have been described. Based on their conserved structure and protein identity, FIPs can be classified into five subgroups: Fve-type FIPs (Pfam PF09259), Cerato-type FIPs (Pfam PF07249), PCP-like FIPs, TFP-like FIPs, and unclassified FIPs. Among the five subgroups, Fve-type FIPs are the most studied for their hemagglutinating, immunomodulating, and anti-cancer properties. In general, these small proteins consist of 110–125 amino acids, with a molecular weight of ~13 kDa. The other four subgroups are relatively less studied, but also show a noticeable influence on immune cells. In this review, we summarized the protein modifications, 3-dimensional structures and bioactivities of all types of FIPs. Moreover, structure-function relationship of FIPs has been discussed, including relationship between carbohydrate binding module and hemagglutination, correlation of oligomerization and cytokine induction, relevance of glycosylation and lymphocyte activation. This summary and discussion may help gain comprehensive understanding of FIPs' working mechanisms and scope future studies.

Abstract
Fungal immunomodulatory protein (FIP) is one of the bioactive compounds of edible mushrooms, which has been shown to trigger type 1 T helper (Th1) pathway activation in research with mice. This study was designated to assess immunomodulatory effects of recombinant FIP-Flammulina velutipes (rFIP-fve) on swine and the protective efficacy against PRRSV infection. In the in vitro evaluations, rFIP-fve significantly triggered up-regulation of IL-2 and IFN-γ mRNA in porcine PBMCs and stimulated natural killer cytotoxicity. Porcine pulmonary alveolar macrophages (PAMs) treated with rFIP-fve showed prolonged life times, up-regulation of both MHC I and II molecules and enhanced abilities to present antigen. In the in vivo trial, two doses of 2 mg rFIP-fve significantly reduced drops in the CD4/CD8 ratio after PRRSV challenge, and the cytokine mRNA profile of PBMC revealed a tendency of IFN-γ up-regulation and a decrease in IL-10 in the rFIP-treated group. Moreover, administration of rFIP-fve also decreased the PRRSV viremia with 1 log10 in titer (p = 0.07) and alleviated the severity of clinical signs after PRRSV challenge. Conclusively, these results illustrate the in vitro and in vivo immunological changes of rFIP-fve administered to pigs and reveal its potential to be used as an immunomodulatory therapeutic against PRRSV infection.

Abstract
This study was conducted to evaluate the effects of dietary FVS supplementation on growth performance, nutrient digestibility, biochemical profile of serum and fecal short chain fatty acids (SCFAs) production in weaned piglets. In Exp.1, 150 weaned pigs (initial body weight: 6.89 ± 1.17 kg) were allotted to five dietary treatments. The treatment diets included a basal diet and four experimental diets supplemented with 2.5%, 5.0%, 7.5% and 10.0% FVS respectively. The animal trial lasted for 28 days. In Exp.2, 72 piglets (initial body weight: 8.20 ± 1.67 kg) were allotted to three dietary treatments. The treatment diets included a basal diet and two experimental diets supplemented with 1.5% and 3.0% FVS, respectively. The animal trial lasted for 56 days. The results showed that pigs fed dietary FVS with 3% or lower inclusion levels had no significant difference (p > 0.10) on growth performance compared with pigs fed the control diet during day 1-28 and day 1-56. Dietary FVS supplementation decreased the apparent total tract digestibility (ATTD) of nutrients on day 28, day 35 and day 56, but no significant changes (p > 0.05) of nutrient digestibility were observed on day 14. Although piglets fed diets with higher levels of FVS showed impaired growth performance and ATTD of nutrients, dietary FVS supplementation improved the fecal SCFA production, antioxidant capacity, interleukin-2 and growth hormone levels in serum, and reduced the harmful low-density lipoprotein levels in serum on day 56. In conclusion, as a promising alternative fibrous ingredient, FVS could be supplemented in diets of weaned piglets with a proportion under 3%.

Abstract
In order to obtain a better fermentation parameter for the production of recombinant Ganoderma lucidum immunomodulatory protein (rFIP-glu), an engineered Pichia pastoris GS115 was investigated on the fermentation time, temperature, methanol concentration and initial pH of media, while immunomodulatory activities of the rFIP-glu was confirmed. L9(33) orthogonal experiment were firstly employed to optimize various fermentation parameters in the shake-flask level. The optimized fermentation parameters were subsequently verified in a 5 L fermenter. Biological activities including cell viability and tumor necrosis factor-alpha (TNF-α) mRNA of the rFIP-glu were evaluated on murine macrophage RAW264.7 cells. The results showed that the yield of rFIP-glu was up to 368.71 μg/ml in the shake-flask, and 613.47 μg/ml in the 5 L fermenter, when the Pichia pastoris was incubated in basic media with the methanol concentration 1.0% and initial pH 6.5, and with constant shaking at 280 rpm for 4 days at 26 °C. In vitro assays of biological activity indicated that rFIP-glu had significant toxicity against RAW264.7 cells, and possessed the ability to induce TNF-α mRNA expression in macrophage RAW264.7 cells. In conclusion, engineered P. pastoris showed a good fermentation property under the optimum fermentation parameters. It could be a candidate industrial strain for further study.

Recombinant Expression and Bioactivity Comparison of Four Typical Fungal Immunomodulatory Proteins from Three Main Ganoderma Species. BMC Biotechnol 2018; 18:80. [PMID: 30547780 PMCID: PMC6295072 DOI: 10.1186/s12896-018-0488-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Accepted: 11/28/2018] [Indexed: 02/09/2023] Open
Abstract
Background More than a dozen of fungal immunomodulatory proteins (FIPs) have been identified to date, most of which are from Ganoderma species. However, little is known about the similarities and differences between different Ganoderma FIPs’ bioactivities. In the current study, two FIP genes termed FIP-gap1 and FIP-gap2 from G. applanatum, along with LZ-8 and FIP-gsi, another two representative Ganoderma FIP genes from G. lucidum and G. sinense were functionally expressed in Pichia. Subsequently, bioactivities of four recombinant Ganoderma FIPs were demonstrated and compared. Results All the four Ganoderma FIP genes could be effectively expressed in P. pastoris GS115 at expression levels ranging from 197.5 to 264.3 mg L− 1 and simply purified by one step chromatography using HisTrap™ FF prepack columns. Amino acid sequence analysis showed that they all possessed the FIP conserved fragments. The homologies of different Ganoderma FIPs were from 72.6 to 86.4%. In vitro haemagglutination exhibited that FIP-gap1, FIP-gsi and LZ-8 could agglutinate human, sheep and mouse red blood cells but FIP-gap2 agglutinated none. Besides, the immunomodulation activities of these Ganoderma FIPs were as: rFIP-gap2 > rFIP-gap1 > rLZ-8 and rFIP-gsi in terms of proliferation stimulation and cytokine induction on murine splenocytes. Additionally, the cytotoxic activity of different FIPs was: rFIP-gap1 > rLZ-8 > rFIP-gsi > rFIP-gap2, examined by their inhibition of three human carcinomas A549, Hela and MCF-7. Conclusions Taken together, four typical Ganoderma FIP genes could be functionally expressed in P. pastoris, which might supply as feasible efficient resources for further study and application. Both similarities and differences were indeed observed between Ganoderma FIPs in their amino acid sequences and bioactivities. Comprehensively, rFIP-gaps from G. applanatum proved to be more effective in immunomodulation and cytotoxic assays in vitro than rLZ-8 (G. lucidum) and rFIP-gsi (G. sinense).

Abstract
Chemoprevention is the use of natural and/or synthetic substances to block, reverse, or retard the process of carcinogenesis. In this field, the use of antitumor peptides is of interest as, (i) these molecules are small in size, (ii) they show good cell diffusion and permeability, (iii) they affect one or more specific molecular pathways involved in carcinogenesis, and (iv) they are not usually genotoxic. We have checked the Web of Science Database (23/11/2015) in order to collect papers reporting on bioactive peptide (1691 registers), which was further filtered searching terms such as "antiproliferative," "antitumoral," or "apoptosis" among others. Works reporting the amino acid sequence of an antiproliferative peptide were kept (60 registers), and this was complemented with the peptides included in CancerPPD, an extensive resource for antiproliferative peptides and proteins. Peptides were grouped according to one of the following mechanism of action: inhibition of cell migration, inhibition of tumor angiogenesis, antioxidative mechanisms, inhibition of gene transcription/cell proliferation, induction of apoptosis, disorganization of tubulin structure, cytotoxicity, or unknown mechanisms. The main mechanisms of action of those antiproliferative peptides with known amino acid sequences are presented and finally, their potential clinical usefulness and future challenges on their application is discussed.

Recombinant FIP-gat, a Fungal Immunomodulatory Protein from Ganoderma atrum, Induces Growth Inhibition and Cell Death in Breast Cancer Cells. JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2016; 64:2690-2698. [PMID: 26996414 DOI: 10.1021/acs.jafc.6b00539] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/05/2023]
Abstract
FIP-gat, an immunomodulatory protein isolated from Ganoderma atrum, is a new member of the FIP family. Little is known, however, about its expressional properties and antitumor activities. It was availably expressed in Escherichia coli with a total yield of 29.75 mg/L. The migration of recombinant FIP-gat (rFIP-gat) on SDS-PAGE corresponded to the predicted molecular mass, and the band was correctly detected by a specific antibody. To characterize the direct effects of rFIP-gat on MDA-MB-231 breast cancer cells, MDA-MB-231 cells were treated with different concentrations of rFIP-gat in vitro; the results showed that this protein could reduce cell viability dose-dependently with a median inhibitory concentration (IC50) of 9.96 μg/mL and agglutinate the MDA-MB-231 cells at a concentration as low as 5 μg/mL. Furthermore, FIP-gat at a concentration of 10 μg/mL can induce significant growth inhibition and cell death in MDA-MB-231 cells. Notably, FIP-gat treatment triggers significant cell cycle arrest at the G1/S transition and pronounced increase in apoptotic cell population. Molecular assays based on microarray and real-time PCR further revealed the potential mechanisms encompassing growth arrest, apoptosis, and autophagy underlying the phenotypic effects.
