Abstract
Converting M2 macrophages into an M1 phenotype in the tumor microenvironment, provides a new direction for tumor treatment. Here, we further report CVPW-1, a new polysaccharide of 1.03 × 106 Da that was isolated from Coriolus versicolor. Its monosaccharide was composed of mannose, glucose, and galactose at a ratio of 1.00:8.73:1.68. The backbone of CVPW-1 was composed of (1 → 3)-linked α-D-Glcp residues and (1 → 3,6)-linked α-D-Glcp residues that branched at O-6. The branch consisted of (1 → 6)-linked α-D-Glcp residues and (1 → 4)-linked α-D-Glap, and some branches were terminated with (1→)-linked β-D-Manp residues according to the results of HPLC, FT-IR, GC-MS, 1D and 2D NMR. Meanwhile, CVPW-1 could polarize M2 macrophages to M1 phenotypein vitro by binding to TLR4 and inducing the activation of Akt, JNK and NF-κB. This process involved reversing the functional inhibition of CD8+ T lymphocytes by inhibiting the expression of TREM2 in M2 macrophages. The in vivo experiments showed that oral administration of CVPW-1 could inhibit the growth of tumor in mice and polarize TAMs to M1 phenotype. Thus, the novel polysaccharide CVPW-1 from Coriolus versicolor might activate a variety of immune cells and then play an anti-tumor role. These results demonstrated that CVPW-1 could be developed as a potential immuno-oncology treatment reagent.

Abstract
Human papillomavirus (HPV) is responsible for virtually all cervical cancers in women. HPV infection and persistency may lead to different-grade squamous intraepithelial lesions that can result in high-grade lesions and cancer. The objective was to prospectively evaluate the results of using a Coriolus-versicolor-based vaginal gel (Papilocare®) on HPV-dependent low-grade cervical lesion repair in a real-life scenario. HPV-positive women ≥ 25 years with ASCUS/LSIL cervical cytology results and concordant colposcopy images were included, receiving the vaginal gel one cannula/day for 21 days (first month) + one cannula/alternate days (five months). A 6-month second treatment cycle was prescribed when needed. Repair of the cervical low-grade lesions through cytology and colposcopy, HPV clearance, and level of satisfaction, and tolerability were evaluated. In total, 192 and 201 patients accounted for the total and safety analyses, respectively, and 77.1% repaired cervical lesions at 6 or 12 months (76.0% for high-risk HPV). Additionally, 71.6% achieved HPV clearance throughout the study's duration (70.6% for high-risk HPV). Satisfaction level was rated 7.9 and 7.5 out of 10 at 6 and 12 months, respectively. Only three mild-moderate product-related adverse events were reported, and all of them were resolved by the end of the study. In our study, we observed higher regression rates of low-grade cervical lesions in women treated with Papilocare® vaginal gel than spontaneous regression rates reported in the literature.

Abstract
Coriolus versicolor (CV) is a common species from the Polyporaceae family that has been used in traditional Chinese herbal medicine for over 2000 years. Among well-described and most active compounds identified in CV are polysaccharopeptides, such as polysaccharide peptide (PSP) and Polysaccharide-K (PSK, krestin), which, in some countries, are already used as an adjuvant agent in cancer therapy. In this paper, research advances in the field of anti-cancer and anti-viral action of CV are analyzed. The results of data obtained in in vitro and in vivo studies using animal models as well as in clinical research trials have been discussed. The present update provides a brief overview regarding the immunomodulatory effects of CV. A particular focus has been given to the mechanisms of direct effects of CV on cancer cells and angiogenesis. A potential use of CV compounds in anti-viral treatment, including therapy against COVID-19 disease, has also been analyzed based on the most recent literature. Additionally, the significance of fever in viral infection and cancer has been debated, providing evidence that CV affects this phenomenon.

Abstract
Melanoma is one of the most aggressive forms of skin cancer and is characterized by high metastatic potential. Despite improvements in early diagnosis and treatment, the mortality rate among metastatic melanoma patients continues to represent a significant clinical challenge. Therefore, it is imperative that we search for new forms of treatment. Trametes versicolor is a mushroom commonly used in Chinese traditional medicine due to its numerous beneficial properties. In the present work, we demonstrate T. versicolor fruiting body and mycelium ethanol extracts exhibit potent cytotoxic activity towards A375 (IC50 = 663.3 and 114.5 µg/mL respectively) and SK-MEL-5 (IC50 = 358.4 and 88.6 µg/mL respectively) human melanoma cell lines. Further studies revealed that T. versicolor mycelium extract induced apoptotic cell death and poly (ADP-ribose) polymerase cleavage, upregulated the expression of autophagy-associated marker LC3-II, increased the presentation of major histocompatibility complex II and expression of programmed death-ligand receptor, and inhibited cell migration in SK-MEL-5 cells. Therefore, our present findings highlight the therapeutic potential of T. versicolor mycelium extract for the treatment of melanoma and merit further study.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Coriolus versicolor (CV) has been used in traditional Chinese medicine for over 2000 years as a premium medicine for enhancing good health and longevity. The immunomodulatory and anti-cancer effects of polysaccharopeptides (PSP) from cultured CV have been extensively studied; however, the effect and the mechanism of action of other small molecules from CV remain unknown. AIM OF THE STUDY we aim to examine the immunomodulatory and anti-cancer effects of the small molecules from CV (SMCV) and identify the active compounds that are responsible for the biological effects against glioblastoma multiforme cells. MATERIALS AND METHODS The effects of SMCV/active compound on cytokine and MMP mRNA expressions and productions were assessed by quantitative reverse transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. An active compound from SMCV was identified with a bioassay-guided fractionation scheme. The potential mode of action of the active compound was further investigated by identifying the cell signaling pathway. The protein expressions of phospho-ERK, phospho-JNK and phospho-p38 MAPKs were measured by Western Blotting. The anti-invasive effect of SMCV/bioactive compound against T98G, lung carcinoma (A549), and breast adenocarcinoma (MDA-MB-231) cells were determined using invasion assay. RESULTS Our results showed that SMCV had strong immunomodulatory effect by suppressing LPS-induced TNF-α production, whereas increasing poly I:C-induced IFN-β level in PBMac. SMCV not only possessed indirect anti-cancer effect by suppressing TNF-α-induced MMP-3 production in glioblastoma T98G cells, but also directly reduced the invasion ability of malignant cells including T98G, A549 and MDA-MB-231. Using bioassay-guided fractionation scheme, we isolated 9-KODE methyl ester (compound AM) that was responsible for the bioactivity of SMCV. This compound suppressed TNF-α-induced MMP-3 production in T98G cells and the suppression may be correlated with the inactivation of p38 mitogen-activated protein kinase (MAPK) pathway. Moreover, compound AM also directly reduced T98G cell invasion. CONCLUSION Results of our present study provides scientific evidence that SMCV possesses immunomodulatory and anti-cancer effects. Its bioactive compound, compound AM, is a potential new drug candidate against the invasion and metastasis of glioblastoma cells.

Abstract
Purpose Extract from the fungus Coriolus versicolor (CV) is classified as an immunological response modifier. Previously, we have shown that this extract induces interleukin 6 (IL-6)-related extension of lipopolysaccharide (LPS)-induced fever. This study investigated the effect of CV extract on the production of pro-inflammatory cytokines and the expression of components of signal transduction pathways leading to the secretion of cytokines from RAW 264.7 macrophages stimulated with different doses of LPS. Methods RAW 264.7 cells were stimulated with CV extract alone or co-treated with CV extract and LPS. The level of IL-6 and tumour necrosis factor α (TNF-α) in the culture media was measured using ELISA. Protein expression of Toll-like receptor (TLR) 4, phosphorylated IκB (p-IκB), CD14 glycoprotein and phospho-phosphatidylinositol 3-kinase (p-PI3K) was evaluated using Western blot. The effects of TLR4, nuclear factor κB (NF-κB) and p-PI3K on cytokine secretion were estimated using inhibitors: TAK-242, JSH-23 and LY294002. Results CV extract itself stimulates the secretion of IL-6 and TNF-α and increases the expression of TLR4, p-IκB and p-PI3K. The presence of CV extract during the treatment of cells with lower concentrations of LPS (10 and 100 ng/mL) increases the cytokine production. Co-stimulation of cells with CV extract and LPS at a higher dose (500 ng/mL) decreases the secretion of cytokines. This effect is related to the changes in the expression of TLR4, CD14 glycoprotein, p-IκB and p-PI3K. Conclusion This is the first report showing that the CV extract-induced production of cytokines is mediated by the PI3K signalling pathway. This extract acts antagonistically or additively with LPS on the production of IL-6 and TNF-α, depending on the LPS concentration. Our results are helpful for illustrating the mechanisms for the immunostimulatory effect of CV extract in inflammatory processes.

Abstract
The immune modulating effects of selected herbs deserve careful studies to gain evidence-based support for their further development. We have been working hard on many items of medicinal herbs to gain insight into their immunomodulatory effects relevant to cancer treatment in particular, while infection control is not excluded. Nine of them have been selected to give the results of our exploration on their biological, particularly immunomodulatory activities. Since Hong Kong people especially favor one medicinal mushroom, viz. Coriolus versicolor, a number of clinical trials using Coriolus for cancer-related studies are included in this review. While immune modulation platforms are being built for relevant studies, a brief account on the research targets and related procedures are given.

Abstract
INTRODUCTION A Coriolus versicolor-based vaginal gel is available for treating women with cervical uterine high-risk human papillomavirus (HPV) infection through re-epithelizing and re-balancing microbiota actions. METHODS A longitudinal retrospective observational study was performed to evaluate efficacy and safety of the gel. Women treated with Coriolus versicolor-based vaginal gel were compared with women not treated with the gel. Both groups were monitored for HPV infection by an HPV DNA test, Pap smear (cytology) and colposcopy at baseline and after 6 months. RESULTS Overall, 183 high-risk HPV positive women were enrolled (97 treated and 86 controls). After 6 months, the HPV DNA test became negative in 67.0% versus 37.2% of treated and controls, respectively (p < 0.0001). Furthermore, 76.1% versus 40.8% registered a colposcopy improvement (p = 0.0005) and 60.4% versus 40.8% showed a remission (p = 0.05), for treated versus controls, respectively. Regarding to cytology, 78.5% of treated versus 37.7% of controls registered an improvement, while 70.8% of treated versus 34.8% of controls had a remission (p < 0.0001 for both variables). At multivariate analyses adjusted for age, smoking habit, and use of estroprogestinic pill, compared to controls, women treated with the gel showed a significantly higher likelihood to experience the clearence of HPV DNA (OR 4.81; 95% 2.43-9.53), and remission at colposcopy (OR 2.30; 95% 1.00-5.31), and cytology (OR 5.13; 95% 2.40-10.96) at 6 months. No adverse event was reported during the follow-up. CONCLUSIONS The use of a Coriolus versicolor-based vaginal gel in high-risk HPV patients is safe and effective based on all examined tests.

Abstract
Coriolus versicolor is an edible medicinal mushroom in China. Two polysaccharides, named as CVPn and CVPa were separated from the dried fruiting bodies of Coriolus versicolor by water extraction and ethanol precipitation. Their chemical structures were well elucidated with overall consideration of monosaccharide composition, methylation analysis and 1D/2D-NMR spectra data. The bioactivities on RAW 264.7 macrophages cells were evaluated, and further structure-bioactivity relationships were concluded. With molecular weight of 29.7 kDa for CVPn and 50.8 kDa for CVPa, the two isolated polysaccharides were both composed of (l → 4)-β-/(1 → 3)-β-d-glucopyranosyl group as backbone with branches attached at O-6 site. Comparing to CVPn, CVPa with relative high molecular weight and less branches showed significant induction of NO production, obvious augmentation of iNOS and TNF-α mRNA expression level, and phagocytosis on RAW 264.7 cells. These results clarified that CVP polysaccharides with less branches and high molecular weight possessed enhanced immunomodulatory ability, and this finding could be a reference for the utilization of Coriolus versicolor.

Abstract
Medicinal mushrooms, Coriolus versicolor and Lentinus edodes are extremely attractive as nutraceuticals. Here we used fruiting bodies to prepare novel kombucha beverage. Microbiological, physicochemical and chemical properties were monitored for eleven days, while the immunological properties of kombucha polysaccharide extracts were determined in peripheral blood mononuclear cell (PBMC) cultures. FTIR analysis of polysaccharide extracts showed dominant presence of polysaccharides, in addition to phenols, lipids and proteins. C. versicolor kombucha extract displayed more complex polysaccharides, and a higher content of total polysaccharides, phenols and flavonoids compared to L. edodes kombucha extract. The extracts were not cytotoxic for PBMC in vitro up to 500 µg/ml, while immunomodulatory effects depended on their chemical compositions. The most prominent effect was on the reduction of Th2 cytokines and IL-10 in PBMC cultures. Based on these results, novel kombucha products could be recommended as functional beverages or nutraceuticals with potentially beneficial immunomodulatory effects in allergies.

Abstract
Coriolus versicolor (L.) Quél. is a higher fungi or mushroom which is now known by its accepted scientific name as Trametes versicolor (L.) Lloyd (family Polyporaceae). The polysaccharides, primarily two commercial products from China and Japan as PSP and PSK, respectively, have been claimed to serve as adjuvant therapy for cancer. In this paper, research advances in this field, including direct cytotoxicity in cancer cells and immunostimulatory effects, are scrutinised at three levels: in vitro, in vivo and clinical outcomes. The level of activity in the various cancers, key targets (both in cancer and immune cells) and pharmacological efficacies are discussed.

Abstract
The ability of Coriolus versicolor medicinal mushroom to grow and accumulate selenium during submerged cultivation in a selenium-fortified medium is examined in this paper. For selenium supplementation, commercial selenium yeast was used. Control, nonenriched sample and reference cultures cultivated in the medium enriched with commercial yeast Saccharomyces cerevisiae were also prepared. The mushroom demonstrated a high ability to accumulate selenium from the added source (around 970 and 1,300 µg/g of dry mycelium weight for samples enriched with selenium in a concentration of 10 and 20 mg Se/L, respectively). The addition of selenium significantly (p ≤ .05) increased the biomass yield, whereas the addition of nonenriched yeast had no significant (p ≤ .05) impact. Furthermore, regression analysis showed statistically significant (p ≤ .05) and positive correlations between the content of Se and Fe (r = .92), Se and Cu (r = .92), Se and Mn (r = .98), and Se and Sr (r = .96), suggesting that selenium incorporation was followed by incorporation of these elements, and led to mineral enrichment of the obtained mycelium. Methanol extracts prepared from mycelium biomass demonstrated a better inhibitory effect on Gram-positive bacterial strains with minimal inhibitory concentrations between <0.3125 and 40 mg/ml. The obtained results showed that selenium yeast could be used for obtaining a potential novel food supplement: mushroom biomass with high selenium content and enhanced mineral composition.

Abstract
BACKGROUND The ability of Coriolus versicolor medicinal mushroom to accumulate and transform selenium from selenourea and sodium selenite into an organic form - l-selenomethionine - during growth in liquid medium is examined in this paper. Additionally, the impact of supplementation on biological activity of the selenated mushroom methanol extracts, as well as their chemical composition, is studied. RESULTS Selenium accumulation was more efficient with sodium selenite application, but biomass yield was significantly lower (1.89 g DW L-1 ) compared to samples enriched with selenourea (4.48 g DW L-1 ). Mushroom sample obtained after growing in liquid medium with selenourea had significantly higher l-selenomethionine content compared to the sample grown in medium with sodium selenite. Selenium-enriched methanol extracts of C. versicolor mushroom showed improved antimicrobial and antioxidant activities compared to non-enriched extract. CONCLUSION Our results suggest that C. versicolor mushroom cultivated in liquid culture enriched with selenourea can be used for the production of novel food supplements with improved selenium bioavailability. More than 30% of total accumulated selenium from selenourea is transformed into l-selenomethionine. Differences in biological activity of methanol extracts can be explained not only by different selenium content but also by the differences in chemical composition of extracts. © 2019 Society of Chemical Industry.

Abstract
A 6 year old Wheaten Terrier mix with a history of collapse and lethargy was referred for evaluation of pericardial effusion. The echocardiogram identified pericardial effusion and a right auricular mass. No sign of metastasis was noted at this time in thoracic radiographs and abdominal ultrasounds. The patient underwent the right auriculectomy via right lateral thoracotomy. Several metastatic masses were located in the visceral aspect of the pericardium at the time of surgery and were all excised. The right auricular mass and pericardial masses were diagnosed as hemangiosarcoma with a sign of metastasis. The patient recovered from surgery uneventfully and was discharged the sixth day after surgery. The patient received doxorubicin followed by cyclophosphamide, piroxicam and Coriolus versicolor extract postoperatively. Pulmonary metastases were noted 229 days and the dog was euthanized 318 days after surgery. No clinical signs were noted until 309 days postoperatively.

Abstract
Background: Cancer incidence and mortality rates keep rising globally. Coriolus versicolor and Ganoderma lucidum related natural products are commonly applied as a complementary therapeutic option for different stages and types of cancers. The aim of this study is to evaluate the efficacy and safety of the products for cancer therapy. Methods: Randomized controlled trials were identified by systematic search over seven databases from inceptions to May 10, 2019. Two independent reviewers extracted data and assessed the study quality. Meta-analyses were performed to pool hazard ratio (HR), risk ratio (RR), mean differences (MD), and 95% CI using random-effects models. The sources of heterogeneity were explored by subgroup analyses and sensitivity analyses. Publication bias was detected by Funnel plots, Begg's test, and Egger's test. Results: Twenty-three trials involving 4,246 cancer patients were included in this work. C. versicolor and G. lucidum related natural products were significantly associated with lower risks of mortality (HR: 0.82; 95% CI: 0.72, 0.94) and higher total efficacy (RR: 1.30; 95% CI: 1.09, 1.55), but not associated with control rate (RR: 1.05; 95% CI: 0.96, 1.14) compared with control treatment. There was no significant difference between C. versicolor related natural products and control treatment in the effect on relapse-free survival (HR: 1.19; 95% CI: 0.91, 1.55). Compared with control treatment, C. versicolor and G. lucidum related natural products had a favorable effect on elevated levels of CD3 (MD: 9.03%; 95% CI: 2.10, 16.50) and CD4 (MD: 9.2%; 95% CI: 1.01, 17.39), but had no effect on the levels of CD8 (MD: -5.52%; 95% CI: -23.17, 12.13), CD4/CD8 (MD: 0.73; 95% CI:-0.45, 1.91), or NK(MD: 5.87%; 95% CI: -1.06, 12.8). Conclusion: In this meta-analysis, we found that C. versicolor and G. lucidum related natural products might have potential benefits on the overall survival and quality of life in cancer patients.

Abstract
Endotoxin tolerance is defined as a reduced endotoxin-induced fever following repeated injections of lipopolysaccharide (LPS). Clinical examples of endotoxin tolerance include sepsis or cystic fibrosis. This state is characterized by inhibition of pro-inflammatory cytokines production and decrease in nuclear factor-kappa B (NF-κB) activation. Extract from Coriolus versicolor (CV) fungus is classified as a biological response modifier, which exhibits various biological activities, including immunopotentiating properties. The aim of study was to examine the effect of CV extract injection on body core temperature of Wistar rats during LPS-induced endotoxin tolerance. Body temperature was measured using biotelemetry. CV extract was injected intraperitoneally (100 mg kg-1) 2 h prior to the first LPS peritoneal administration (50 μg/kg). Endotoxin tolerance was induced by three consecutive daily injections of LPS at the same dose. We also investigated the influence of CV extract pre-injection on the properties of peripheral blood mononuclear cells (PBMCs) isolated from LPS-treated rats in response to LPS stimulation ex vivo. PBMCs were isolated 2 h after the first LPS injection. After 24 h pre-incubation, the cells were stimulated with LPS (1 μg ml-1) for 4 h. Our results revealed that CV extract partially prevents endotoxin tolerance through maintaining febrile response in rats following consecutive exposure to LPS. This state was accompanied by the ability of PBMCs isolated from rats injected with CV extract and LPS to release larger amounts of interleukin 6 and greater NF-κB activation in response to LPS stimulation ex vivo compared with the cells derived from rats injected only with LPS. Data also showed that CV extract augmented mitogenic effect of LPS on PBMCs and caused increase in reactive oxygen species generation. We concluded that CV extract, by a modifying effect on body temperature during endotoxin tolerance, can be consider as the immunostimulating agent, which prevents the non-specific refractoriness described in patients with sepsis or ischemia.

Abstract
Coriolus versicolor is an herb widely used for cancer treatment in traditional Chinese medicine. Its active ingredients, polysaccharopeptides (PSP), have been used for adjuvant therapies in cancer treatment. This study conjugates Coriolus versicolor PSP with poly(ethylenimine) (PEI) to generate a PSP-PEI copolymer for gene transfer. After PEI conjugation, both the pH buffering capacity and DNA compaction ability of PSP are significantly increased. Compared with that of PSP, the transfection efficiency of PSP-PEI is 10 to 20-fold higher in vitro. This is a proof-of-concept study reporting the direct use of bioactive phytochemicals from traditional Chinese medicine for gene vector development. The promising performance of PSP-PEI raises the possibility that bioactive herbal ingredients can be further developed as a multi-therapeutic gene carrier for tackling cancers.

Abstract
Various Chinese herbal medicines (CHMs) have shown beneficial liver protection effects. Jian-Gan-Bao (JGB), a functional herbal formula, consists of three famous CHMs, including Coriolus versicolor, Salvia miltiorrhiza and Schisandra chinensis, which has been used as a folk medicine for several chronic liver diseases. In the present study, we aim systemically to evaluate the effects of JGB on acute and chronic alcoholic liver diseases (ALD) as well as non-alcoholic fatty liver disease (NAFLD) in mouse models, and identify its potential bioactive components and mechanism of action. JGB showed preventive effects for acute and chronic ALD as well as NAFLD, while post-treatment of JGB showed no significant effect, suggesting the nature of JGB as a health supplement rather than a drug. Furthermore, a compound-target network was constructed to identify the potential bioactive compounds and pathways that regulate its hepatoprotective effects. There are 40 bioactive compounds and 15 related targets that have been identified via this network pharmacology study. Among them are miltirone, neocryptotanshinone II and deoxyshikonin, with desirable pharmaceutical properties. Pathways relating to inflammation, fatty acid oxidation, tumor necrosis factor (TNF) production and cell proliferation were predicted as bioactive compounds and potential underlying mechanisms, which should be the focus of study in this field in the future.

Abstract
Coriolus versicolor (CV) contains high levels of bioactive compounds, including the glucan (1→6)-α-D-glucopyranosyl. However, there is a lack of data regarding the potential effect of this CV glucan (CVG) on the stimulation of cytokine production. The present study evaluated the effect of CVG on the stimulation of cytokine production in sarcoma-180-bearing mice. Mice were treated with three doses of CVG (40, 100 or 200 mg/kg body weight) for nine days, after which serum levels of cytokines, namely interleukin (IL)-2, -4, -6, -10, -17A and interferon (IFN)-α and -γ, were investigated by ELISA. CVG significantly promoted the secretion of IL-2, -4, -6, -10, -17A and IFN-α and -γ at the doses of 100 (P<0.05) and 200 (P<0.01) mg/kg, but not at 40 mg/kg (P>0.05), when compared with cyclophosphamide treatment, as a positive control. Additionally, cytokine production associated with T helper (Th)2 and Th17 cells was enhanced compared with that of Th1 cytokines, and the immunomodulatory function of CVG appeared to be IL-10-dependent. These results demonstrate that CVG may stimulate the production of cytokines and serve as a Th2/IL-10-dependent immunomodulator, and thus has promise in supporting cancer therapies.

Abstract
Traditional uses of herbal medicine have depended mostly on anecdotal evidence for much of history. The increasing application of scientific rigor to the study some of these traditional therapies in recent years has revealed potent bioactivity, notably demonstrated by the 2015 Nobel Prize for the discovery of an antimalarial compound from traditional Chinese herbs. Given the recent successes of immunotherapy and checkpoint blockade, there is a renewed interest in identifying new drugs with immunomodulatory effects. As an estimated 45-60% of cancer patients worldwide are reported to use complementary alternative medicine alongside traditional therapy, this review will highlight the literature on the immunomodulatory effects of one of these compounds. We report on the induction of a largely pro-inflammatory cytokine profile by the polysaccharopeptide (PSP) isolated from the Coriolus versicolor (Yun zhi) mushroom, as well as its effects on various immune subsets, and the clinical data that have led to its widespread adoption as an adjunct cancer therapeutic in many Eastern cultures. Particular focus is given to the potential mechanisms underlying the bioactivity of PSP and reports of its ability to promote antitumor immunity by helping overcome tolerogenic tumor microenvironments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Coriolus versicolor (CV) is a mushroom traditionally used for strengthening the immune system and nowadays used as immunomodulatory adjuvant in anticancer therapy. Breast cancer usually metastasizes to the skeleton, interrupts the normal bone remodeling process and causes osteolytic bone lesions. The aims of the present study were to evaluate its herb-drug interaction with metronomic zoledronate in preventing cancer propagation, metastasis and bone destruction. MATERIALS AND METHODS Mice inoculated with human breast cancer cells tagged with a luciferase (MDA-MB-231-TXSA) in tibia were treated with CV aqueous extract, mZOL, or the combination of both for 4 weeks. Alteration of the luciferase signals in tibia, liver and lung were quantified using the IVIS imaging system. The skeletal response was evaluated using micro-computed tomography (micro-CT). In vitro experiments were carried out to confirm the in vivo findings. RESULTS Results showed that combination of CV and mZOL diminished tumor growth without increasing the incidence of lung and liver metastasis in intratibial breast tumor model. The combination therapy also reserved the integrity of bones. In vitro studies demonstrated that combined use of CV and mZOL inhibited cancer cell proliferation and osteoclastogenesis. CONCLUSIONS These findings suggested that combination treatment of CV and mZOL attenuated breast tumor propagation, protected against osteolytic bone lesion without significant metastases. This study provides scientific evidences on the beneficial outcome of using CV together with mZOL in the management of breast cancer and metastasis, which may lead to the development of CV as adjuvant health supplement for the control of breast cancer.

Abstract
BACKGROUND The majority of patients with hepatocellular carcinoma (HCC) are inoperable and results with conventional chemotherapy are dismal. Many end up with no treatment options and resort to alternative medicine. The authors report the use of Coriolus versicolor (CV) in advanced HCC patients with poor liver function or who were unfit to receive standard therapy. METHODS Fifteen eligible cases were randomized 2:1 to either CV or placebo. The primary endpoint was the median time to progression (TTP) between both arms. Secondary endpoints include evaluating response rates, toxicity, quality of life (QOL), progression-free survival (PFS), and overall survival (OS). Further correlative studies were performed looking at the effect of CV on the immune system. RESULTS The median treatment duration was 1.5 cycles and 3 cycles on the placebo and CV arm, respectively. Median TTP was 2.5 (1.4-5.3) months compared to 4.2 (0.4-4.2) months in the CV and placebo arm, respectively, hazard ratio (HR) 0.70 (0.16-3.05 p = 0.634). Median PFS was 2.5 (1.4-5.3) months in the CV and 1.1 (0.4-4.2) months in the placebo arm, HR 0.42 (0.13-1.34, p = 0.144). Median OS was 6.5 (3.3-24.1) and 2.2 (0.8-23.3) months, respectively, HR 0.35 (0.10-1.25, p = 0.105). Social and emotional functioning scores were higher in the CV group compared to placebo group on treatment. CV subjects had less appetite loss and pain symptoms compared to placebo subjects during treatment. CONCLUSIONS There was no difference in TTP with use of CV compared to placebo. CV subjects generally had better QOL on treatment compared to placebo subjects. The utility of this supplement in patients whose primary treatment goal is palliation should be further explored.

Abstract
BACKGROUND To assess the effect of a 12-day treatment using a vaginal gel based on niosomes containing hyaluronic acid, ß-glucan, alpha-glucan oligosaccharide, Coriolus versicolor, Asian centella, Azadirachta indica and Aloe vera on vaginal microbiota, cervical epithelization and vaginal health. METHODS Open-label, prospective pilot study conducted in asymptomatic women in daily practice. Cervical epithelization was evaluated by colposcopy using an ectopy epithelization score (from 5: no ectopy to 1: severe ectopy and bleeding), vaginal microbiota using the VaginaStatus-Diagnostic test (Instiüt für Mikroökologie, Herborn, Germany) and further rated by the investigator using a 5-point Liker scale (from 5: normal to 1: very severe deterioration in which all evaluated species were altered), and vaginal health using the Vaginal Health Index. RESULTS In 21 women, a positive effect to improve epithelization of the cervical mucosa, with a mean score of 4.42 at the final visit as compared to 3.09 at baseline (P < 0.0001) (43% improvement). In 10 women, there was a trend of improving of vaginal microbiota status, with a mean score of 4.0 at the final visit vs. 3.3 at baseline (P = NS) (21.2% improvement). In 11 women, the Vaginal Health Index increased from 19.0 at baseline to 22.3 at the final visit (P = 0.007). The concentration of Lactobacillus spp. increased 54.5% of women and pH decreased from 4.32 to 4.09. CONCLUSIONS These encouraging preliminary results provide the basis for designing a randomized controlled study, and for potential use in human papilloma virus infection.

Abstract
In this study, Coriolus versicolor mycelia (CVM) was evaluated the ergogenic and anti-fatigue activities. Male ICR mice were divided into four groups (n = 8/group) to receive vehicle or CVM by oral gavage for 4 weeks at 0, 615, 1230 or 3075 mg/kg/day, which were respectively designated the vehicle, CVM-1X, CVM-2X and CVM-5X groups. Forelimb grip strength, endurance swimming time, and levels of physical fatigue-associated parameters serum lactate, ammonia, glucose and creatine kinase (CK) after physical challenge were performed to evaluate exercise performance and anti-fatigue activity. Results revealed that the forelimb grip strength of mice in group CVM-1X, CVM-2X and CVM-5X were significantly increased by 1.20-, 1.18- and 1.23-fold, respectively, compared to the vehicle group. After the 15 minute swimming exercise, the levels of serum lactate of CVM-1X, CVM-2X and CVM-5X groups were significantly lower than the vehicle control group by 29%, 23% and 31%, respectively. The levels of ammonia in CVM-1X, CVM-2X and CVM-5X groups were significantly lowered by 22%, 25% and 41%, respectively, compared to the vehicle control group. In addition, the levels of serum CK in CVM-2X and CVM-5X groups were significantly lowered by 13% and 11%, respectively, compared to the vehicle control group. Accordingly, the supplementation with CVM has beneficial effects on performance improvement and anti-fatigue activity, and thus has great potential as a source for natural health products.

Abstract
The aim of the study was to explore whether fever-range hyperthermia (FRH) might enhance the anticancer and immunoregulatory activities of protein-bound polysaccharides (PBP), a class of fungus derived immunomodifiers used in the cancer adjuvant therapy. Blood lymphocytes and breast cancer cells (MCF-7) were cultured at 39.5°C in humidified atmosphere containing 5% CO2 for 2h. After rested at 37°C for 6h, the cells were treated with PBP extract at 100- and 300μg/ml concentration. After indicated time, the proliferative response was analyzed and cytokine mRNA expression assessment was performed by qRT-PCR. In animal model, the FRH was induced by placing rats in the Homeothermic Controller with heating blanket. Animals were heated until Tb reached 39.5°C (±0.2°C) and were maintained at this temperature for 30min. The protein-bound polysaccharides solution was injected i.p. at a dose of 100 mg/kg 6h post FRH. Twenty four hours after treatment, the blood was collected and cytokines expression analysis were performed. The results have shown that fever-range hyperthermia has an inhibitory effect on PBP extract-induced proliferative response of blood lymphocytes, as well as IL-1β and IL-6 mRNA expression. Moreover, the temperature of 39.5°C blocks PBP-induced cytotoxicity against MCF-7 cells, which correlates with significant reduction in TNF-α level. Combined treatment of rats (FRH+PBP) results in decrease of IL-1β, IL-6 and TNF-α mRNA expression in peripheral blood mononuclear cells compared to cells derived from rats treated with protein-bound polysaccharides extract alone. This study demonstrates that fever-range temperature inhibits immunostimulatory as well as anticancer effects mediated by protein-bound polysaccharides.

Abstract
Protein-bound polysaccharides (PBP) isolated from Coriolus versicolor (CV) are classified as biological response modifiers capable of exhibiting various biological activities, such as anti-tumour and immunopotentiating activity. Since we have found in vivo studies that the tested PBP induced prolongation of endotoxin fever in rats, the aim of the present study was to investigate the in vitro effect of the PBP on the production of pro-inflammatory cytokines by the lipolysaccharide (LPS)-stimulated rat peripheral blood mononuclear cells (PBMCs). The results showed that the PBP affect the immunomodulating properties of the LPS-treated PBMCs by the enhancement of mitogenic activity and attenuation of the LPS-induced production of interleukin (IL)-1β and IL-6. Moreover, the tested polysaccharides peptides themselves also exhibit immunomodulatory properties manifested in the increased cell proliferation and pro-inflammatory cytokine release from PBMCs. The effect of PBP on the both phenomena was time-dependent and occurred in the U-shaped dose response manner. These findings are significant when considering the use of commercially available PBP from CV extract by cancer patients suffering from immunodeficiency, who may experience microbial infections during therapy.

Abstract
The antibacterial activity of methanol extract obtained from fruiting body of industrially grown basidiomycete Coriolus versicolor was examined. The Minimum Inhibitory Concentration (MIC) values against various bacteria ranged from 0.625 to 20 mg mL(-1). C. versicolor expressed bactericidal activity against both Gram-positive and Gram-negative bacteria. The growth curves of Staphylococcus aureus and Salmonella enterica serovar Enteritidis, measured at 630 nm, and confirmed with macrodilution method showed that the obtained extract could inhibit the growth of tested bacteria. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and the loss of 260-nm-absorbing material were used to examine the ultrastructural changes in bacteria induced by the extract. When S. aureus was exposed to the MIC of C. versicolor, elongated and malformed cells were observed by SEM, while S. Enteritidis treated cells appeared shorter and aggregated with ruptured cell walls. TEM revealed the formation of non-membrane-enclosed bodies and depleted inner content of S. aureus. Larger and irregular periplasmic space and deformed and scattered components of the cell envelope were observed in treated S. Enteritidis. The loss of 260-nm-absorbing material indicated that the disruptive action of the extract on cytoplasmic membrane was more pronounced in S. aureus than in S. Enteritidis treated cells. The UV and FTIR spectrophotometric analyses revealed diverse composition of C. versicolor extract and high content of total phenolics. Altogether, mushroom extracts could be used to develop nutraceuticals or drugs effective against pathogenic microorganisms.

Abstract
The protein-bound polysaccharides (PBP), isolated from Coriolus versicolor (CV) fungus, are considered as natural compounds with potential therapeutic applications. The immunopotentiating and antitumor activity of polysaccharopeptides has been previously examined, however similar findings could not be achieved. The source of PBP, variations in extraction process as well as environmental factors seems to affect the biological properties of these active CV components. Since further analysis are needed to draw more definite conclusion, the present study aimed to investigate the immunomodulatory properties of the PBP extract, isolated from commercially available capsules of C. versicolor. Our results revealed that the effect mediated by PBP extract depends on the target cells. We reported that the polysaccharopeptides induced a significant decrease in breast cancer MCF-7 cells growth, which was TNF-α-dependent phenomenon. Interestingly, the level of two others cytokines, IL-1β and IL-6 was not affected. On the other hand, in this study we noticed that protein-bound polysaccharides extracted from CV significantly augmented the proliferative response of blood lymphocytes in a time-dependent manner, which was associated with IL-6 and IL-1β mRNA upregulation. Moreover we found that the cells response to PBP stimuli might be inversely related to its concentration.

Abstract
Background Coriolus versicolor (CV) is a common mushroom with antitumor, anti-inflammatory, antioxidant, antiviral, antibacterial, and immunomodulatory properties. The existence of these properties has been extensively proven mainly using CV extract; research on the biomass form is scarce. Objective The aim of this study was to investigate the safety of the CV biomass form, as it is commonly used as a food supplement. Design CV biomass powder was dissolved in distilled water and administered daily (2.5, 5.0, and 7.5 g/kg live weight) in single doses by gavage to both female and male Charles River albino rats. Results No adverse or lethal effects were observed as a consequence of the daily administration of CV biomass. In addition, compared with the control group, no abnormal findings were observed at necropsy and histopathological examination. Conclusions A safe profile of CV biomass for human consumption can be inferred from the absence of any remarkable adverse effects in rats.

Abstract
The effects of β-glucans from Coriolus versicolor (CVP), which are extracted from a well-known immune stimulator C. versicolor, have been demonstrated extensively in vitro and in vivo. However, until now, the phagocytic activity has not been elucidated. Hence, the objective of the present study was to identify the antibacterial activity of CVP or CVP-treated macrophages by an analysis of cell cytotoxicity, phagocytic activity, intracellular bacterial survival, macrophage activation, production of nitric oxide (NO) and expression of inducible nitric oxide synthase (iNOS) in CVP-treated macrophages using flow cytometry, RT-PCR, a gentamicin protection assay, a Nitric oxide assay and an iNOS enzymatic activity assay. The results indicate that CVP-treated macrophages can phagocytize and kill bacteria, probably due to the production of NO and iNOS. More importantly, CVP-treated macrophages are effective at protecting mice against the challenge of Salmonella typhimurium. The results of this study suggest that the antibacterial effects of CVP are probably caused by the activation of innate immune cells, especially macrophages, because the activated macrophage produces NO, which kills bacteria. These phenomena indicate the possibility of CVP as a potential alternative for antibiotics against resistant bacteria.

Abstract
BACKGROUND Polysaccharide K, also known as PSK or Krestin, is derived from the Coriolus versicolor mushroom and is widely used in Japan as an adjuvant immunotherapy for a variety of cancer including lung cancer. Despite reported benefits, there has been no English language synthesis of PSK for lung cancer. To address this knowledge gap, we conducted a systematic review of PSK for the treatment of lung cancer. METHODS We searched PubMed, EMBASE, CINAHL, the Cochrane Library, AltHealth Watch, and the Library of Science and Technology from inception to August 2014 for clinical and preclinical evidence pertaining to the safety and efficacy of PSK or other Coriolus versicolor extracts for lung cancer. RESULTS Thirty-one reports of 28 studies were included for full review and analysis. Six studies were randomized controlled trials, 5 were nonrandomized controlled trials, and 17 were preclinical studies. Nine of the reports were Japanese language publications. Fifteen of 17 preclinical studies supported anticancer effects for PSK through immunomodulation and potentiation of immune surveillance, as well as through direct tumor inhibiting actions in vivo that resulted in reduced tumor growth and antimetastatic effects. Nonrandomized controlled trials showed improvement of various survival measures including median survival and 1-, 2-, and 5-year survival. Randomized controlled trials showed benefits on a range of endpoints, including immune parameters and hematological function, performance status and body weight, tumor-related symptoms such as fatigue and anorexia, as well as survival. Although there were conflicting results for impact on some of the tumor-related symptoms and median survival, overall most randomized controlled trials supported a positive impact for PSK on these endpoints. PSK was safely administered following and in conjunction with standard radiation and chemotherapy. CONCLUSIONS PSK may improve immune function, reduce tumor-associated symptoms, and extend survival in lung cancer patients. Larger, more rigorous randomized controlled trials for PSK in lung cancer patients are warranted.

Abstract
Coriolus versicolor (CV), a medicinal mushroom widely consumed in Asian countries, has been demonstrated to be effective in stimulation of immune system and inhibition of tumor growth. The present study aimed to investigate the anti-tumor and anti-metastasis effects of CV aqueous extract in mouse mammary carcinoma 4T1 cells and in 4T1-tumor bearing mouse model. Our results showed that CV aqueous extract (0.125-2 mg/ml) did not inhibit 4T1 cell proliferation while the non-cytotoxic dose of CV extract (1-2 mg/ml) significantly inhibited cell migration and invasion (p<0.05). Besides, the enzyme activities and protein levels of MMP-9 were suppressed by CV extract significantly. Animal studies showed that CV aqueous extract (1 g/kg, orally-fed daily for 4 weeks) was effective in decreasing the tumor weight by 36%, and decreased the lung metastasis by 70.8% against untreated control. Besides, micro-CT analysis of the tumor-bearing mice tibias indicated that CV extract was effective in bone protection against breast cancer-induced bone destruction as the bone volume was significantly increased. On the other hand, CV aqueous extract treatments resulted in remarkable immunomodulatory effects, which was reflected by the augmentation of IL-2, 6, 12, TNF-α and IFN-γ productions from the spleen lymphocytes of CV-treated tumor-bearing mice. In conclusion, our results demonstrated for the first time that the CV aqueous extract exhibited anti-tumor, anti-metastasis and immunomodulation effects in metastatic breast cancer mouse model, and could protect the bone from breast cancer-induced bone destruction. These findings provided scientific evidences for the clinical application of CV aqueous extract in breast cancer patients.

Abstract
The study was conducted to evaluate effect of Coriolus versicolor mycelia on degrading starch and improving nutrition value in corn grits through solid state fermentation technique. The results showed that using soybean meal as a nitrogen source, α-amylase secreted from C. versicolor expressed 407.25U/g of activity, leading to 45.15% of starch degraded. The activity grew with fermentation time until the 15th day, after that the amylase was deactivated rapidly. An orthogonal experiment designed for the study illustrated that degradation rate of starch in corn grits attained to maximum, 50.51%, when 100g of corn grits, added 16g of soybean meal, were fermented by C. versicolor for 12 days, in an initial pH 5.5. After fermenting, compared to the nonfermented control, contents of amino acids, total sugar, crude fat and crude protein were increased by 21.00%, 38.45%, 55.56%, 69.15% respectively. The significant improvement of nutrition value in corn grits is probably attributed to the intense metabolism of C. versicolor.

Abstract
Nitric oxide (NO) is a reactive free radical and a messenger molecule in many physiological functions. However, excessive NO is believed to be a mediator of neurotoxicity. The medicinal plant Coriolus versicolor is known to possess anti-tumor and immune-potentiating activities. In this study, we investigated whether Coriolus versicolor possesses a protective effect against NO donor sodium nitroprusside (SNP)-induced apoptosis in the human neuroblastoma cell line SK-N-MC. We utilized 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry, 4,6-diamidino-2-phenylindole (DAPI) staining, terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay, DNA fragmentation assay, reverse transcription-polymerase chain reaction (RT-PCR), Western blot analysis, and caspase-3 enzyme activity assay in SK-N-MC cells. MTT assay showed that SNP treatment significantly reduces the viability of cells, and the viabilities of cells pre-treated with the aqueous extract of Coriolus versicolor cultivated in citrus extract (CVEcitrus) was increased. However, aqueous extract of Coriolus versicolor cultivated in synthetic medium (CVEsynthetic) showed no protective effect and aqueous citrus extract (CE) had a little protective effect. The cell treated with SNP exhibited several apoptotic features, while those pre-treated for 1 h with CVEcitrus prior to SNP expose showed reduced apoptotic features. The cells pre-treated for 1 h with CVEcitrus prior to SNP expose inhibited p53 and Bax expressions and caspase-3 enzyme activity up-regulated by SNP. We showed that CVEcitrus exerts a protective effect against SNP-induced apoptosis in SK-N-MC cells. Our study suggests that CVEcitrus has therapeutic value in the treatment of a variety of NO-induced brain diseases.
