Comparsion of Anti-cancer Effect between two kinds of Polysaccharide Peptide of Coriolus versicolor on Human Tumor Cell Lines in Vitro

L.Z. Xu Laboratory of Pathology Cancer Institute, Shanghai Medical University

Abstract

In the present study the anti-cancer effect of polysaccharide peptide of Coriolus versicolor Cov-1 (PSP) was compared with polysaccharide peptide of Coriolus versicolor CM-101 (PSK) on four human tumor cell line targets (SGC 7901, stomach cancer cell; SPC, human lung adenocarcinoma cell; SLY, human monocytic leukemia cell and Mei, human skin histiocytic lymphoma cell) in Vitro.

PSP had similar cytotoxic effects upon human tumor cells as PSK, both inhibiting cell growth. In comparison with control specimens, the SPC cell line treated with PSP (1000ug/ml) for 72 hours at 37oC showed marked morphological changes such as cell swelling, chromatin aggregation, formation of polynuclear cells and sawtooth on the surface of cell nuclei.

PSK as a new immunomodulative drug had been widely used for clinical anticancer therapy in Japan. When combined with chemotherapy, radiotherapy and surgical operation, PSK is found to be able to improve the therapeutic effects. In 1983, a polysaccharide peptide of Coriolus versicolor Cov-1 was isolated from the mycelia by Qing-yao Yang. It is possessed of physio-chemical characteristics similar to PSK and designated as PSP. In the present study the anti-cancer effect of PSP was compared with PSK using four human tumor cell line targets in vitro.

In vitro inhibition of proliferation of HL-60 cells by tetrandrine and coriolus versicolor peptide derived from Chinese medicinal herbs.

Coriolus versicolor polysaccharide peptide (CVP) and the bis-benzylisoquinoline alkaloids, tetrandrine (TET) and berbamine (BER), the active ingredients isolated from Chinese medicinal herbs known to possess antitumor activities, concentration-dependently inhibited the proliferation of human leukemic HL-60 cells. CVP did not affect the growth of normal human peripheral blood lymphocytes (PBL), whereas TET elicited concentration-dependent cytotoxic effects. Morphological observation and DNA analysis revealed that CVP elicited no effect on the morphological features of HL-60 cells and did not cause DNA fragmentation, but TET and BER caused cell shrinkage with the formation of apoptotic bodies, and showed clear evidence of DNA fragmentation. These findings indicate that TET and BER, but not CVP, inhibited the proliferation of HL-60 cells via induction of apoptosis.

Polysaccharopeptide from the mushroom Coriolus versicolor possesses analgesic activity but does not produce adverse effects on female reproductive or embryonic development in mice.

Coriolus versicolor polysaccharopeptide has been reported to exert immunomodulatory and antitumor actions. The present study showed that it exhibits analgesic activity in the hot-plate test upon intraperitoneal administration to ICR mice. 2. It did not affect ovarian steroidogenesis, ovulation and midterm gestation in mice. It did not exert an adverse effect on mouse embryonic development either, as evidenced by the lack of an effect on somite number, axial length and the incidence of abnormalities in heartbeat, yolk sac circulation, optic vesicle, otic vesicle, shape of body axis, forelimb buds, branchial apparatus, cranial neural tube and head size. 3. Its analgesic activity would add to its attribute as an immunomodulatory and antitumor drug.

Treatment of cancer with mushroom products.

Cancer has been attributed to 3 causes: pollution, infection, and poor nutrition. Conventional treatments include surgery, chemotherapy, and radiotherapy. The author proposes that immunotherapy also be considered. Among other environmental influences, dietary deficiencies and carcinogenic viral infections must be investigated and treated wherever possible. It has been suggested that mushrooms, in particular, have a structure that is immunomodulatory because it resembles the proteoglycan structure in the human extracellular matrix, and both are metabolically active. Inasmuch as mitochondria have a bacterial origin, proteoglycans may have a mushroom origin. The author describes a study which shows that natural killer cells can double in number with 8 wk of treatment with Coriolus versicolor. Also described is an epidemiological survey of cancer deaths among Flammulina velutipes farmers in Japan, which found that the mushroom farmers had lower rates of cancer deaths than controls who were not involved in mushroom farming?

Clinical Experience in the Use of PSP

Cancer Hospital, Shanghai Medical University

Abstract

There is no really effective treatment for moderate and advanced stages of esophageal
carcinoma. Although surgery for the earlier cases has been able to give a 5 years survival
rate of 28.7%, such operable cases are relatively few. By far the greater majority are
already in stage III to IV when first seen in the clinic, and radiotherapy alone in these cases
has given a 5 years survival rate of only 8-14%. In order to improve treatment results, a
variety of chemotherapeutic agents have been used in combination surgery, but so far no
really effective drug has been found.

The drug PSP (polysaccharide-peptide of Coriolus versicolor) has been discovered and
produced by Professor Qing-yao Yang of. It is a new anti-cancer and immuno-regulatory
drug, similar to PSK (Krestin) but the effective component has been found to be larger
than PSK. Experimental data has proved these properties of PSP, and in vitro as well as
in vivo studies have all proved that PSP is superior to PSK. Of course, as is the case with
all new drugs, the ultimate proof of its value will have to be shown by clinical application.

Data on Krestin suggest that this family of drugs when used in combination with
radiotherapy, there might be an increase of the biological effects of radiation. To do a
pilot study on such a possibility, the authors have treated 41 moderate to advanced cases of
esophageal carcinoma with a combination of PSP and radiotherapy.

CRISTINA FERRARE TO HOST NEW INFOMERCIAL

Irvine, Californa (December 6, 2010) inLife LLC, distributors of science-based Health & Wellness products today announced that a new infomercial hosted by TV personality Cristina Ferrare will begin airing December 28 and will feature inLife’s new ground-breaking immune building product, inForce. “We are very excited to be working with Cristina Ferrare as our infomercial host”, stated Craig Youngblood, CEO and Founder of inLife.

About Coriolus Versicolor

The Coriolus versicolor mushroom is one of the most widely studied immune building supplements. Worldwide, there have been over 400 animal and human studies on PSK & PSP, both polysaccharide extracts of the Coriolus versicolor mushroom with over a dozen placebo-based human trials conducted in the west. Traditionally, the Coriolus versicolor mushroom (known as Yun-zhi or cloud mushroom in China) has been used in China for several thousand years because of its immune boosting capabilities. In the 1980s, Dr. Yang conducted further studies and was able to isolate a much more potent strain using a different, alcohol-based extraction process. The result was Polysaccharopeptide or PSP. In the United States, top-ranked hospital and research institutes have reported that Coriolus versicolor helps boost the body’s immune system with limited side effects and safety of daily oral doses for extended periods of time. In addition, Coriolus versicolor and its potential positive effects has been studied very closely by M.D. Anderson, University of Texas, Loma Linda University, Beth Israel Deaconess Medical Center (a teaching hospital of Harvard Medical School) , The University of San Diego, Sloan-Kettering Center (New York), and Bastyr University (Kenmore, Washington), just to name a few.

inLife Immune Builder with PSP and PSK

inLife offers Coriolus versicolor as a Daily Dietary Supplement in capsule form to help maintain and stimulate the body’s immune system. Coriolus versicolor and its high-potency extracts, PSK and PSP are among the most widely studied supplements for their immune building properties and the incredibly positive results of these studies are compelling. InForce Immune Builder is a proprietary blend of both Polysaccharide-K (PSK) and Polysaccharopeptide (PSP). Both offer valuable immune building assistance and can be taken on a daily basis. The products are bottled in the United States in an FDA registered bottling facility that is CGMP compliant (Current Good Manufacturing Practices).
