Glycoproteins in mushrooms - the coming cancer treatment

Readers may have seen the front page news in the UKs Daily Express (November 2009). A page and a half was devoted to US research that showedmedicinal mushrooms (in this case shitake, Japanese mushrooms) not onlyboosted the immune systems of people trying to fight cancer, but actuallyhelped increase survival times for 70 per cent of cancer patients when used as a complementary therapy.

We are not surprised. This is not the first time medicinal mushrooms have appeared to help fight cancer.


Medicinal mushrooms have a number of actions and are covered more fully if you follow this link (click here).


Here in this article we focus on glycoproteins:

Glycoproteins are sugars, and based on polysaccharide chains of glucose. But glucose is the favourite food of a cancer cell, I hear you scream. Well, polysaccharides can neither be broken nor built in the human body. You have to ingest them in their unique configurations, and then off they go to do their work.


And when you look below at the list of top foods containing them, you will realise why junk food really is junk food.


Research on glycoproteins



Four Nobel Prizes for Medicine in recent years (1994, 1999, 2000 and 2001) have been won with research on how cells communicate, and its importance to our health & wellbeing.

Whilst one of them was specifically concerned with the brain and how nerve cells communicate through chemicals with each other (Arvid Carlsson et al 2000), the other three were concerned with communications to cells around the body and all had implications for cancer prevention and treatment.

In 1994 Gilman and Rodbell won for their discovery of "G - proteins and their role in signal transduction in cells". Basically they investigated how Iocalised cells handle signal substances from glands, nerves and other tissues to make changes.

In 1999 Gunter Blobel and his team looked at how proteins have specific protein signals built into them so that they reach the correct destinations.

And by 2001 Hartwell, Hunt and Nurse had won for showing an understanding of the cellular messages involved in the cell cycle -its growth and division into two identical daughter cells - and how mistakes might result in a cancer development.

These protein messages often involve carbohydrate molecules, or sugars, and so a generic term glycoproteins is the word coined for this hot topic.

A Simple Explanation


Several aspects of glycoproteins are important.

Blobel sought to understand a genetic mystery. When your DNA string is read and the code says you should have blue eyes or blond hair, how does the message get to the right place?

As a foetus in the womb, each of us started out with a fused cell from our parents that multiplied at an incredibly rapid rate. But around day 42-46 something (largely thought to be a message from the pancreas) tells these cells, called stem cells, to turn into eye cells or hair cells, and to stop dividing so rapidly and instead to adopt a normal cell cycle.

Cancer cells resemble stem cells and do not seem to have received the signal to differentiate

The interest for cancer scientists is that cancer cells resemble stem cells and do not seem to have received the signal to differentiate. Blobel found that the messages sent out contained little "postcodes" directing the message to the intended cells. Furthermore he discovered that these signals contain the ability to go through the cell membrane and so influence the mechanism of the cell inside

Cell Membranes - Barriers To Health


Cell membranes, like all tissue, are largely made up of fats or lipids, protein and carbohydrate. If you think of each molecule as a pin, with a pinhead, alternately pointing in opposite directions but in a neat line, you will have a picture of a healthy membrane. Messages can thus slip in between the pins. It is the role of glycoproteins to encourage this "neatness" and thus allow the messages through.

The problem comes when the pins are not in this neat format and are fused or at various angles, not allowing anything through. Worse sometimes modest amounts of carbohydrate are bonded to the membranes. Where tumour cells have this carbohydrate, it is used to bind to other cells and cause them to turn rogue too, hence causing metastasis. Killer cells in your immune system look out for these carbohydrate-bonded sites.

Blobels work focused on what happens when there are errors in the signals, while Hartwell et al focused on what happens when the cell cycle goes haywire.

What This Means To You And Me


The need for healthy signalling and message flow has led to a focus on glycoproteins. Professor Gilbon-Garber has shown, for example, that the invasive process of bacteria, viruses and indeed cancer cells which involves the above "bonding" process to membranes, can be inhibited by glycoproteins in mothers milk.

Because these molecules used in her experiments are all-natural, no side effects occurred

Because these molecules (from mothers milk, saliva and semen) used in her experiments are all-natural, no side effects occurred.

This has important implications. "Drugs" could be built on natural substances, with no side effects.

So Where Can I Get Them?


A number of naturally occurring substances have already been identified as having high glycoprotein content. Not surprisingly one was medicinal mushrooms.

Reishi, maitake, cordyceps, shiitake and oyster mushrooms all have beta-glucan polysaccharide. There have been a number of well documented studies on these medicinal mushrooms, which boost the immune system, aid communication between immune cells and rogue cells, and help considerably in the anti-cancer fight. One fun story Cancer Research UK reported was that Japanese mushroom pickers have half the cancer rates of the rest of the population. (They obviously scrump!).

Other natural sources of these essential sugars are:

Aloe vera, brans - slow cooked oatmeal, whole barley, brown rice, pectins - apples and citrus fruit eaten wholebreast milk, arabinogalactins - found in wheat, leeks, carrots, radishes, pears, red wine, coconut, meat, tomatoes, curcumin and echinacea, corn, psyllium, garlic.

The interesting factor is the universality of the discovery. All cells seem to positively respond to glycoproteins, whether they are human, yeast, plants or animals.

Even tiny amounts of these sugars - or lack of them - have a profound effect.

One integrated cancer expert we spoke to said that glycoproteins would be more important than all discoveries like vitamin C, B17 and genistein added together!

However, it is worth noting that you should ensure you incorporate the above foods into your diet. Despite all the Nobel Prizes, any supplements for glycoproteins are unlikely to be on the new EU approved lists, as the directive now stands!

Cat's Claw Treats Cancer and Boosting the Attack


Alkaloids are very powerful natural plant compounds and there are six oxindole alkaloids in Uno de Gato bark. This natural compound is found in the Peruvian rain forest and China. It is known to be anti-viral, anti-inflammatory, an antioxidant and an immune stimulator.


An excellent Immune System booster


A common misconception is that merely stimulating the immune system will be enough to kick out a cancer. Maybe, in a few cases it will. But, by and large, the problem with cancer is two-fold true, the immune system is weak, BUT .......the cancer evades the immune system because of the low immune system response capacity. (In English the bad guys cant be seen, no matter how many good guys you produce. The issue is to make lots of good guys AND stimulate the bad guys in such a way that they appear on the radar screens).

So, in Herbal Medicine two therapeutic requirements are essential when treating cancer Immuno-modulating herbs, and Adaptogenic herbs, and BOTH are required to work synergistically

If you are thinking of buying Cats Claw, you might like to look at the Natural Selection Product of Choice. You can do this by clicking this link.

Cats Claw is an immuno-modulating herb - it is known to increase various white cell levels stimulating the production of Natural Killer Cells. Four alkaloids in particular boost phagocytosis where the white cells attack, wrap up and carry off the rogue cells in the body be they microbes, viruses, antigens and even cancer cells.

Research studies have shown the herb to be very powerful in its use with AIDS and cancer therapies. Research shows an action in decreasing the size of some tumours.

Do we think it is a cancer ´cure´? No. At CANCERactive we think no single compound (Drug or natural) is likely to be a cure for cancer. However it may be useful as part of your overall programme.

Cat´s Claw seems to protect healthy cells during radio- and chemotherapy


Research shows that Cat´s Claw may reduce the damaging side effects from radiotherapy and chemotherapy, as it seems to offer protection to healthy cells and enhances the attacking and removal of cancer cells.

It may also be combined with wild yam and aloe vera forming a very strong anti-viral, anti-bacterial, immune boosting force.

It has also been shown to boost the bodys natural energy levels. You should take one gram a day on an empty stomach.

First Hand experience


If you are thinking of buying Cats Claw, you might like to look at the Natural Selection Product of Choice. You can do this by clicking this link.

I witnessed personally that Cats claw, astragalus, turmeric (curcumin) and echinacea can be an excellent immune system re-booting combination for cancer patients, and especially after treatment with radiotherapy or chemotherapy. We gave this combination to Catherine when the chemotherapy drugs had reduced her white cells to desperately low levels, and the standard immune-stimulating drugs and injections on offer simply would not work even though she tried them daily for weeks. On taking the four herbs her white cell levels recovered in less than two weeks! She was also taking aloe vera which most probably helped further.

Turmeric equals exercise in its ability to prevent cancer and aging

A chemical that naturally occurs in turmeric root appears to protect the heart from aging as much as moderate aerobic exercise, according to a trio of studies conducted by researchers from theUniversity of Tsukuba in Japan.

Turmeric root has been an important component of traditional Asian medicinal systems for hundreds of years. In recent decades, scientific studies have confirmed the potent anti-inflammatory and antioxidant properties of the trio of turmeric chemicals known as "curcuminoids," which give the root its distinctive yellow-orange color. Although only one of these chemicals is properly known as "curcumin," the name is commonly used to refer to all of them collectively.

The three new studies all compared the effects of exercise and curcumin on heart health and postmenopausal women over an eight-week period. All the studies were randomized, double-blind and placebo-controlled. Curcumin was delivered by means of colloidal nanoparticles.

Can turmeric prevent heart disease?

In the first study, researchers assigned 32 women to either take a curcumin supplement, engage in moderate aerobic exercise training, or undergo no intervention at all. The researchers measured participants' vascular endothelial function - the responsiveness of the layer of cells that line the blood vessels, a key indicator of overall cardiovascular health - both at the beginning and end of the study. They found that while there was no improvement in the control group, endothelial function significantly increased in both the exercise and curcumin groups. Most surprisingly, the improvement in the two experimental groups was identical.

The second study examined curcumin's effects on the responsiveness of arteries to changes in blood pressure ("arterial compliance"), another key measure of cardiovascular health. In this study, 32 women were randomly assigned to receive either a curcumin supplement or a placebo pill, or to undergo an exercise routine plus either a curcumin or placebo pill. The researchers found no significant improvement in the control group, significant (and equivalent) improvements in both the exercise-only and curcumin-only groups, and the greatest improvement among participants who exercised and also took the supplements.

In the final study, researchers examined the effects of exercise and curcumin on the rate of age-related degeneration of the heart's left ventricle. 45 participants were randomly assigned into one of the same four groups used in the second study.

The researchers once again found that both exercise and curcumin produced significant increases in heart health. In this study; however, curcumin alone did not appear to provide any benefit. Specifically, brachial systolic blood pressure (SBP) decreased among participants who exercised, whether or not they took curcumin. In addition, heart-rate-corrected aortic augmentation index (AIx) and aortic SBP both decreased significantly only among participants who both exercised and took curcumin.

"Regular ingestion of curcumin could be a preventive measure against cardiovascular disease in postmenopausal women," the authors of the first study wrote. "Furthermore, our results suggest that curcumin may be a potential alternative ... for patients who are unable to exercise."

Curcumin is best absorbed from turmeric root, rather than from supplements.




No cancer has been found that is not affected by turmeric

Curcumin has many serious fans in the fight to beat cancer - UCLA, the MD Anderson Cancer Center, the Emory School of Medicine and Tufts to name but four important American Cancer Centers. Why? It is a powerful antioxidant that is also anti-viral and anti-bacterial; plus it seems to have great potential to fight cancer, especially colorectal cancer. All people wishing to build an anti-cancer programme should think seriously about including curcumin within it.

The anti-cancer action of curcumin (turmeric):

        * Importantly, the spice can stop the action of the enzyme COX-2 known to produce negative, inflammation causing localised enzymes (eicosanoids). Such inflammation is a known precursor to cancer.
        * It has also been shown to inhibit vascular epithelial growth factors. Every tumour needs a blood supply - the growth factors build one, but curcumin seems to stop them.
        * It has been shown to ´re-awaken´ a key tumour surpressor gene. 
        * It has been shown to inhibit metastases.                
        * It has been shown to kill cancer cells (B lymphoma cells).
        * It prevents regrowth of cancer stem cells which lie at the heart of many tumours

More research is being reported every month!

For example, in the journal ´Genes and Nutrition´ (2011, 6(2) 93-108) the whole issue of ´Epigenetics´ was exposed. It used to be thought that your genes controlled all and a problem in a gene meant you were in someway ´doomed´. This theory has been disproven and replaced by one that shows genes are just your blueprint; these blueprints are controlled, activated or surpressed by the localised environment. So hormones can affect their action, as can natural compounds in food. And curcumin seems to affect gene expression significantly. Such ´signalling pathways´ have been shown to be affected by curcumin.

An example of this ´signalling pathway´ modification came in research from theLudwig-Maximilians University in Munich, Germany in 2012 which showed thatcurcumin can inhibit the formation of metastases in both prostate and breast cancer.  Both cancers spread throughout the body through the release of chemical messengers, pro-inflammatory cytokines CXCL1 and CXCL2, but curcumin alters the expression of these two damaging proteins.

Next, Cheryl Myers (head of Scientific Affairs and Education for EuroPharma Inc.) refers to curcumin as ´the anti-cancer herb´ because of its success in stopping cancer formation, replication and spread. Research also shows that curcumin increases the activity of certain anti-cancer drugs whilst protecting healthy cells and organs. It has been proven to reduce systemic inflammation and oxidative stress.

And researchers from the Dept. of Natural Science at Middlesex Universityhave shown that curcumin and chokeberry can work together to induce cancer cell death (apoptosis) and stop the spread of malignant cancer cells. Their report (in Oncology Reports) was for brain tumours.

Dr Young S. Kim leading a team at the National Cancer Institute in America showed that curcumin was one of the natural compounds that could prevent cancer stem cells from re-growing and re-forming the cancer tumour. Her conclusion even suggested patients could supplement! 

The biggest fans seem to reside at the MD Anderson Cancer Center in Texas. From Cancer Watch April 2011 comes this note:

Professor Bharat Aggarwal Ph. D. in MD Andersons Department of Therapeutics has conducted a number of studies, for example showing that in pancreatic cancer patients having no chemotherapy, it reduced tumour size. He believes it is effective against many types of cancer because it suppresses angiogenesis (the growth of blood vessels essential to a tumour).

Indeed he goes further: "No cancer has been found, to my knowledge, which is not affected by curcumin," Aggarwal says. "The reason curcumin is so effective against cancer is that it hits not just a single target or cell signalling pathway but dozens of targets implicated in cancer."

It has also been shown to have a strong synergistic effect against cancer with resveratrol, and also with EGCG in green tea.

Taking a Curcumin supplement

Curcumin supplements provide curcumin in good amounts but curcumin is difficult is difficult to absorb. Absorption can be helped by piperine the active ingredient in black pepper. This also seems to enhance some of its actions.

According to the American Cancer Society absorption can be improved by mixing the supplement with a teaspoonful of olive oil and sprinkling the black pepper on it. Don´t spill it on your skin or clothes - it stains.

So is curcumin a cure for cancer? No, of course not. What is exciting the experts in cancer centres in America is that it can play a role against several of the steps in what is a multi-step cancer process. As such it would seem stupid to ignore it as a part of an Integrative or holistic cancer treatment programme.

What are curcumin and turmeric?

Curcumin is the active ingredient of the Indian/Asian curry spice Turmeric.  To put this technically, curcumin is the principal curcuminoid in turmeric.  Curcuminoids are polyphenols.  Turmeric powder is ground from the root of a plant called Curcuma Longa, which is a member of the ginger family and is found throughout Southern Asia, even growing wild in the Himalayas.
This vivid yellow to brown spice was used, like many Asian spices and chillies, to hide the taste of stronger tasting meats and fish even those that might have gone a little off in such hot climates.  Like many such spices, it also performed a necessary and functional role it was a cleanser, a bacteria-killer in the stomach, protecting against tainted foods!

Wide activity


Curcumin first caught my attention when I read a research report on its ability to prevent the crossed wires of Alzheimers, through blocking a certain peptide forming.  Therapeutic doses seem able to prevent, and also reverse, early stages of the disease.  (My father had the disease, in case you wondered!).  As I started to do my homework, I found clinical trials for all manner of illnesses from cystic fibrosis to reduction of risk in stomach and colorectal cancers.
The research is coming thick and fast. You will find the latest in Cancer Watch

Curcumin/turmeric has been used in Ayurvedic medicine for thousands of years as a cleanser of the body.  It appears to work at a number of levels:

1. It can inhibit unwanted bacterial action in the stomach and intestine:
For example (i) , University of Chicago researchers have shown it inhibitsHeliobacter pylori, a bacterium known to be responsible for stomach ulcers and some stomach cancers.  In Ayurvedic medicine, curcumin was used in poultices for this same reason to kill unwanted bacteria.

2. It is a significant anti-inflammatory:
Arachidonic acid is a precursor/stimulator of the production of bad eicosancids (see our reviews of omega 3 and vitamin D) and thus to inflammation, which is itself a precursor to certain cancers.  Curcumin has been found to inhibit several of the pre-inflammatory enzymes (e.g. COX2 and iNOS) in vitro and in vivo with animals.  Japanese research suggests it works in much the same way as salicylin. (ii)

3. It boosts crucial cellular glutathione levels:
Glutathione is a crucial intracellular antioxidant, helping the cell maintain its correct oxygen levels and fight off the effects of stress hormones.  Research has shown that curcumin can prevent the action of an enzyme that limits glutathione production.

4. It is a powerful antioxidant:
Turmeric extract tested more potent than garlic, omega 3 and cat´s claw (devil´s claw) said German research. (iii)

5. It can help prevent liver damage
2010 research from St Louis has shown that it can turn off a protein called Leptin, which causes liver damage. It has also been shown to be capable of detoxifying the liver. Thus curcumin may be of help in keeping the liver healthy during chemotherapy cancer treatments.(vii)

6. It can prevent and even ´treat´ cancer:
As we have covered above, curcumin can suppress tumour initiation, promotion and metastasis.  Extensive research over the last 50 years has indicated it can prevent and treat cancer. The anti-cancer potential stems from its ability to control gene signalling, and affect a wide variety of tumour cells, down-regulate transcription factors, down-regulate enzymes such as COX-2 and other inflammatories, cytokines, chemokines, cell-surface adhesion molecules, down-regulate growth factors, etc., etc. (iv)

But, its not just me that are fans:

Tufts have conducted research with breast cancer patients concluding that curcumin and isoflavanoids seem to inhibit the action of environmental oestrogens. (v)

UCLA have researched its potential with colorectal cancer (San Diego, Chauhen). And there are Clinical Trials underway (according to the Mayo Clinicto investigate curcumin as a way to prevent cancer in people with precancerous conditions, as a cancer treatment, and as a remedy for signs and symptoms caused by cancer treatments.

Kentucky University researchers report on its inhibition of B lymphoma cells. (vi)

Emory School of Medicine showed that it attacked Vascular Endothelial Growth Factors cutting the ability of tumours to generate their essential blood supply lines. Many drugs are being developed specifically to stop VEGF´s, but this common spice already does the job

Memorial Sloan-Kettering (New York) even offered that ´green tea spiced with curcumin was a double anti-cancer beater´!

There are a dozen or more studies where curcumin has caused cell death in cancer cells; and even more where it prevents tumours forming a blood supply.

However as always, some things seem too good to be true; and despite the euphoria of major hospitals in the USA, a few words of realism have to be added.



Firstly, much of the work original used cell cultures.  Increasingly studies use a variety of animals, and there have been human trials, even clinical trials, primarily with cervical cancer lesions and with gastrointestinal cancers.  So, although the biochemical knowledge is vast, the use of oral curcumin to prevent and treat cancer is still in its infancy.



Next, there is a problem maintaining effectiveness inside the cells; there are several studies that show oral consumption needs to be maintained in order to maintain blood and cellular levels.  But it is not as simple as curry every day!
