Immunomodulatory activities of Yunzhi and Danshen in post-treatment breast cancer patients.

Breast cancer is the most common cancer among women worldwide. Discomfort and fatigue are usually arisen from anticancer therapy such as surgery, radiotherapy, chemotherapy, hormonal therapy, or combination therapy, because of the suppressed immunological functions. Yunzhi (Coriolus versicolor) can modulate various immunological functions in vitro, in vivo, and in human clinical trials. Danshen (Salvia miltiorrhiza) has been shown to benefit the circulatory system by its vasodilating and anti-dementia activity. The purpose of this clinical trial was to evaluate the immunomodulatory effects of Yunzhi-Danshen capsules in post-treatment breast cancer patients. Eighty-two patients with breast cancer were recruited to take Yunzhi [50 mg/kg body weight, 100% polysaccharopeptide (PSP)] and Danshen (20 mg/kg body weight) capsules every day for a total of 6 months. EDTA blood samples were collected every 2 months for the investigation of immunological functions. Flow cytometry was used to assess the percentages and absolute counts of human lymphocyte subsets in whole blood. Plasma level of soluble interleukin-2 receptor (sIL-2R) was measured by enzyme-linked immunosorbent assay (ELISA). Results showed that the absolute counts of T-helper lymphocytes (CD4+), the ratio of T-helper (CD4+)/T suppressor and cytotoxic lymphocytes (CD8+), and the percentage and the absolute counts of B-lymphocytes were significantly elevated in patients with breast cancer after taking Yunzhi-Danshen capsules, while plasma slL-2R concentration was significantly decreased (all p < 0.05). Therefore, the regular oral consumption of Yunzhi-Danshen capsules could be beneficial for promoting immunological function in post-treatment of breast cancer patients.[…]

Induction of cell cycle changes and modulation of apoptogenic/anti-apoptotic and extracellular signaling regulatory protein expression by water extracts of I’m-Yunity (PSP).

Aqueous extracts of I’m-Yunity (PSP) induces cell cycle arrest and alterations in the expression of apoptogenic/anti-apoptotic and extracellular signaling regulatory proteins in human leukemia cells, the net result being suppression of proliferation and increase in apoptosis. These findings may contribute to the reported clinical and overall health effects of I’m-Yunity (PSP).[…]

Characterisation and bioactivity of protein-bound polysaccharides from submerged-culture fermentation of Coriolus versicolor Wr-74 and ATCC-20545 strains.

The protein-bound polysaccharides of Coriolus versicolor (CPS) have been reported to stimulate overall immune functions against cancers and various infectious diseases by activating specific cell functions. A New Zealand isolate (Wr-74) and a patented strain (ATCC-20545) of C. versicolor were compared in this study. The fruit bodies of both strains were grown for visual verification. Both strains were grown in submerged-culture using an airlift fermentor with milk permeate as the base medium supplemented with glucose, yeast extract and salt. Metabolic profiles of both strains obtained over 7-day fermentation showed very similar trends in terms of biomass production (8.9-10.6 mg/ml), amounts of extracellular polysaccharide (EPS) from the culture medium (1150-1132 microg/ml), and intracellular polysaccharide (IPS) from the mycelium (80-100 microg/ml). Glucose was the dominant sugar in both EPS and IPS, and the polymers each consisted of three molecular weight fractions ranging from 2 x 10(6) to 3 x 10(3 )Da. Both the EPS and IPS were able to significantly induce cytokine production (interleukin 12 and gamma interferon) in murine splenocytes in vitro. Highest levels of interleukin 12 (291 pg/ml) and gamma interferon (6,159 pg/ml) were obtained from samples containing Wr-74 IPS (0.06 microg/ml) and ATCC 20545 IPS (0.1 microg/ml), respectively. The results indicated that lower levels of EPS and IPS generally resulted in higher immune responses than did higher polymer concentrations.[…]

[Coriolus versicolor–innovation in prevention of oncogynecological diseases, especially HPV]

Coriolus-MRL is a nutrient adjuvant, which contains biomass of the fungus Coriolus versicolor and is studied to reverse early stages of cervical cancer and to reduce risk factors of reoccurring HPV virus.[…]

Polysaccharopeptide enhances the anticancer activity of doxorubicin and etoposide on human breast cancer cells ZR-75-30.

In search of natural bioactive microbial compounds with adjuvant properties, we have previously showed that the polysaccharopeptide (PSP), isolated from Chinese medicinal mushroom Coriolus versicolor, was able to enhance the cytotoxicity of certain S-phase targeted-drugs on human leukemic HL-60 cells via some cell-cycle and apoptotic-dependent pathways. The present study aimed to investigate whether the synergism of mechanisms of PSP with certain chemotherapeutic drugs also applies to human breast cancer. PSP treatment enhanced the cytotoxicity of doxorubicin (Doxo), etoposide (VP-16) but not cytarabine (Ara-C). Bivariate bromodeoxyuridine (BrdUrd)/DNA flow cytometry analysis estimated a longer DNA synthesis time (Ts) for the PSP treated cancerous cells suggesting that PSP enhanced the apoptotic effect of Doxo and VP-16 via creating an S-phase trap in the human breast cancer cell line ZR-75-30. The participation of PSP in the apoptotic machinery of the chemotherapeutic agents was further supported by a reduced ratio of protein expression of Bcl-xL/Bax of the cancer cells. This study provides further insight into the synergistic mechanisms of PSP and supports the hypothesis that the anticancer potentials of PSP is not limited to leukemia but may also be used as an adjuvant therapy for breast cancers.[…]

Protein-bound polysaccharide-K (PSK) directly enhanced IgM production in the human B cell line BALL-1

Protein-bound polysaccharide-K (PSK) prepared from the basidiomycete Coriolus versicolor has been used as a biological response modifier for the treatment of cancer patients. Many studies describing the immunomodulatory effects and direct anti-cancer effects of PSK have been reported. Most of studies describing the immunomodulatory effects focused on cellular immunity, although there were several studies which focused on humoral immunity where PSK was shown to be able to induce antibody production in vivo. However, even in these humoral immunity studies, it is thought that the enhancement of antibody production was due to the activation of cellular immunity. In this study, we investigated the direct effect of PSK on B cells and discovered that PSK was able to enhance IgM production in the human B cell line BALL-1. Furthermore, BALL-1 was shown to have the characteristic features of B-1a cells, which are independently involved in the primary immune response. These results show that there is a possibility that PSK directly acts on B cells and simultaneously enhances both humoral immunity and cellular immunity.[…]

Add mushrooms to list of cancer treatment tools – By: Dr. Patrick Massey, M.D., Ph.D., Daily Herald Columnist

(Daily Herald – 9/8/2008) When it comes to cancer treatment, I believe that we have finally reached a point where we need to seriously consider incorporating mushrooms into the overall medical approach.

A review article outlining the importance of one specific mushroom – Coriolus versicolor – in the treatment of several types of cancer was published in the recent issue of the Journal of the Society for Integrative Oncology. The article summarizes more than three decades of solid research that showed patients who consumed Coriolus versicolor or one of its extracts during chemotherapy had better survival rates. […]

Hartford Hospital, Conneticut & Coriolus Vericolor PSK/PSP

What Hartford Hospital in Conneticut has to say about Coriolus Versicolor “Currently, extracts of Coriolus versicolor called polysaccharide-K (PSK) and polysaccharopeptide (PSP) are under study as immune stimulants for use alongside chemotherapy in the treatment of cancer. These two related substances, made from slightly different strains of the fungus, are thought to act as “biological […]
