... Moreover, some prescriptions show antitumor efect in several mouse tumor models [4][5][6][7][8][9][10][11], although they remain controversial. Recently, we demonstrated the antitumor efect of Juzentaihoto (JTT) (Shi-Quan-Da-Bu-Tang in Chinese and Sipjeondaebo-Tang in Korean) in CD1d −/− mice whose immune-suppressing efects were partly palliated because of the loss of both antitumoral type I and immunosuppressive type II natural remaining ingredients other than Trapae fructus have been reported to have some antitumoral activity [18][19][20][21][22]. Te origin formula of WTMCGEP included Wisteria foribunda, Terminalia chebulae, Trapa natans, and Coicis semen (WTTC), which has been used for treating cancers in Japan since the 1960s [23]. ...
... Tese fndings emphasize the pivotal role of WTMCGEP in reinforcing antitumor immunity through CD8 + T cells in a tumorbearing host on the condition that immunosuppression is partly mitigated because of defciency of NKT cells. Although six of the seven ingredients of WTMCGEP have already been known to possess some antitumor properties [13][14][15][16][18][19][20][21][22], only anecdotal evidence on the antitumor efect of this mixture itself exists. Terefore, to our best knowledge, this is the frst time when WTMCGEP's contribution to enhancing the immunological antitumor efect in vivo is shown. ...

Among the seven ingredients of WTMCGEP, Ganoderma lucidum may be the most studied as an anticancer agent and is known to have anticancer efects in vitro and in vivo, controversies remain [13][14][15][16]. However, the fve remaining ingredients, other than Trapae fructus, have also been reported to have anticancer properties [18][19][20][21][22]. Terefore, WTMCGEP's antitumor efect may not depend on or may be more potent than Ganoderma lucidum alone. ...
Although Kampo—a traditional Japanese herbal medicine—contributes in the control of tumor growth in vivo in experimental animals, most of the antitumor effects are prophylactic and not therapeutic. In this study, we determined whether oral administration of an herbal mixture containing Ganoderma lucidum (WTMCGEP; Wisteria floribunda, Trapae fructus, Myristica fragrans, Coicis semen, Ganoderma lucidum, Elfvingia applanata, and Punica granatum), anecdotally used in Japan for the palliative care of patients with cancer, exhibits a therapeutic effect on tumor growth in vivo in a hypodermic murine CT26 colorectal tumor model. An in vitro tumor assay revealed that WTMCGEP extract has some direct influence over suppression of tumor growth. In wild-type BALB/c mice, WTMCGEP did not show any antitumor effect in vivo. However, in BALB-CD1d−/− mice with partly mitigated immunosuppression by reason of them being devoid of both antitumoral type I and immunosuppressive type II natural killer T (NKT) cells, WTMCGEP therapeutically suppressed tumor growth. CD8+ T cell depletion significantly accelerated tumor growth in WTMCGEP mice; therefore, its antitumor activity was primarily in a CD8+ T cell-dependent manner. Regarding immunosuppressive cells in tumor-bearing CD1d−/− mice, WTMCGEP did not influence the abundance of tumor-infiltrating CD4+ and Forkhead box protein 3+ regulatory T cells. However, it reduced both intratumoral and splenic Ly6G+ Ly6Clo polymorphonuclear myeloid-derived suppressor cells, which were most likely involved in tumor growth inhibition related to higher frequency of intratumoral CD107a+ CD8+ T cells in these mice. Overall, these data illustrate that the deficiency of NKT cells urges WTMCGEP to exert a therapeutic antitumor effect mainly through CD8+ T cells. Our efforts are the first to scientifically demonstrate the WTMCGEP’s contribution to tumor immunity.
... HW fractions had no significant cytotoxic effects on four cell lines at the tested concentrations. In our earlier study, hot water extract from the fruiting body of Elfvingia applanata did not inhibit proliferation of HT-29, Hep G2, TR, and sarcoma 180 cancer cells [18]. In another study, Lee et al. [19] reported that a hot-water extract of Inonotus obliquus exerted little inhibitory activity against proliferation of human colon cancer cells, showing good agreement with our results. ...
Pleurotus nebrodensis is an edible and commercially available mushroom in Korea. This study was conducted in order to evaluate the anticancer and immunopotentiating activities of crude polysaccharides, extracted in methanol, neutral saline, and hot water (hereafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of P. nebrodensis. β-Glucan and protein contents in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. nebrodensis ranged from 23.79~36.63 g/100 g and 4.45~6.12 g/100 g, respectively. Crude polysaccharides were not cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at a range of 10~2,000 µg/mL. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 11.76~27.06% in mice previously inoculated with sarcoma 180. Treatment with Fr. NaCl resulted in an increase in the numbers of spleen cells by 1.49 fold at the concentration of 50 µg/mL, compared with control. Fr. HW improved the immuno-potentiating activity of B lymphocytes through an increase in alkaline phosphatase activity by 1.65 fold, compared with control at 200 µg/mL. Maximum production of nitric oxide (14.3 µM) was recorded in the Fr. NaCl fraction at 200 µg/mL. Production of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) was significantly higher, compared to control, and IL-6 production was highest, in contrast to TNF-α, IL-1β, and positive control, concanavalin at the tested concentration of the various fractions. Results of the current study suggest that polysaccharides extracted from P. nebrodensis have a strong anticancer effect and may be useful as an ingredient of biopharmaceutical products for treatment of cancer.

This study was initiated in order to investigate the anticancer and immunomodulating activities of crude polysaccharides extracted in methanol, neutral saline, and hot water (hereinafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of Panellus serotinus. Content of β-glucan and protein in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. serotinus ranged from 22.92~28.52 g/100 g and 3.24~3.68 g/100 g, respectively. In vitro cytotoxicity tests, none of the various fractions of crude polysaccharides were cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at the tested concentration. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 23.53~44.71% in mice previously inoculated with sarcoma 180. Treatment with Fr. HW resulted in an increase in the numbers of spleen cells by 1.3 fold at the concentration of 50 µg/mL compared with control. Treatment with Fr. NaCl resulted in improvement of the immuno-potentiating activity of B lymphocytes by increasing the alkaline phosphatase activity by 1.4 fold, compared with control, at the concentration of 200 µg/mL. Among the three fractions, maximum nitric oxide (13.48 µM) was recorded at 500 µg/mL in Fr. HW. Production of tumor necrosis factor alpha, interleukin-1β, and interleukin-6 was significantly higher, compared to the positive control, concanavalin A, at the tested concentration. Therefore, treatment with crude polysaccharides extracted from the fruiting body of P. serotinus could result in improvement of antitumor activity.
Here we report 3 cases of advanced cancer using multidisciplinary treatment including reibaisan (WTMCGEP, a dry extract of Wisteria floribunda, Trapa natans, Myristica fragrans, Coix semen, Ganoderma lucidum, Elfvingia applanata, Punica granatum). Case 1 : 87-year-old man, suffering from stage IV esophageal squamous cell carcinoma (ESCC) with aortic and bronchial invasion, was referred to our clinic for palliative care. He had radiotherapy and chemotherapy. Only one course of chemotherapy was performed due to its intolerable side effects. The treatment with reibaisan started 11 months after the diagnosis. ESCC disappeared after 17 months of reibaisan treatment, and no relapse was observed for 66 months after the diagnosis. Case 2 : 79-year-old man, suffering from stage III ESCC, was initially scheduled for surgery after preoperative chemotherapy. Only one course of preoperative chemotherapy was performed because of its intolerable side effects. Therefore, radiotherapy combined with reibaisan followed. ESCC disappeared 6 months later, and no relapse was observed for 33 months after the diagnosis. Case 3 : 73-year-old woman, suffering from stage IV pancreatic cancer with systemic metastasis (brain, lung, and peritoneum). She initially showed Trousseau syndrome and was treated with low-molecular-weight heparin for multiple cerebral infarctions. One-month palliative chemotherapy and reibaisan resulted in a rapid reduction of ascites and improvement of neurological symptoms. Her progression-free survival period was 7 months. She lived 13 months thereafter. This suggests that reibaisan, which contains crude drugs that have been shown to have antitumor effects, may be another promising treatment for advanced cancers.
Mushrooms provide a reliable source of bioactive compounds and have numerous nutritional values, which is one of the reasons why they are widely used for culinary purposes. They may also be a remedy for several medical conditions, including cancer diseases. Given the constantly increasing number of cancer incidents, the great anticancer potential of mushrooms has unsurprisingly become an object of interest to researchers. Therefore, this review aimed to collect and summarize all the available scientific data on the anti-cancer activity of mushroom extracts. Our research showed that mushroom extracts from 92 species, prepared using 12 different solvents, could reduce the viability of 38 various cancers. Additionally, we evaluated different experimental models: in vitro (cell model), in vivo (mice and rat model, case studies and randomized controlled trials), and in silico. Breast cancer proved to be sensitive to the highest number of mushroom extracts. The curative mechanisms of the studied mushrooms consisted in: inhibition of cancer cell proliferation, unregulated proportion of cells in cell cycle phases, induction of autophagy and phagocytosis, improved response of the immune system, and induction of apoptotic death of cells via upregulation of pro-apoptotic factors and downregulation of anti-apoptotic genes. The processes mainly involved the expression of caspases -3, -8, -9, AKT, p27, p53, BAX, and BCL2. The quoted results could lead to the classification of mushrooms as nutraceuticals used to prevent a variety of disorders or to support treatment of cancer diseases.
In the US market, there is a variety of mushroom preparations available, even within the same species of mushroom. Nonetheless, little is known about whether species or the various extraction methods affect biological activity and potency of the immune modulatory activity of mushroom extracts. After discovering that protein-bound polysaccharide-K, a hot water extract from Trametes versicolor, was a potent Toll-like receptor (TLR)-2 agonist that stimulates both innate and adaptive immunity, this study was initiated to evaluate whether other medicinal mushroom products also have TLR2 agonist activity and immune-enhancing potential as measured by the induction of tumor necrosis factor (TNF)-α in J774.A1 murine macrophage cells. Furthermore, the products were divided by extraction method and species to determine whether these factors affect their immunomodulatory activity. The results showed that the majority (75%) of mushroom products tested had TLR2 agonist activity and that there was a significant correlation between TLR2 agonist activity and TNF-α induction potential in the mushroom products analyzed. In addition, the data demonstrated that hot water mushroom extracts are more potent than ground mushroom products in activating TLR2 and inducing TNF-α. These data provide evidence that extraction methods may affect the biological activity of mushroom products; thus, further studies are warranted to investigate the structural differences between various mushroom products.
