Epigenetic Factors to Reduce Breast Cancer Risk – Part 6

Epigenetic Factors to Reduce Breast Cancer Risk – Part 6

In this 11-part series of articles, my primary goal is to empower you with information about the nutrients that can alter epigenetic factors to help you heal from breast cancer and to reduce your risk of recurrence.

For more information on my personal reasons for putting this information together, see Part 1 of the series.

This article, Part 6 of the series, shares the nutrients that have the ability to modify or restore receptors on the surface of breast cancer cells. The function of receptors on cells is to create a place for a chemical messenger (for instance, a hormone) to dock, which then allows the chemical messenger to direct the function of that particular cell.

65-70% of breast cancers are hormone receptor positive, meaning that the tumor cells have receptors to which estrogen can attach (known as “ER-positive”, or “ER+” breast cancer) and/or progesterone (known as “PR-positive” or “PR+” breast cancer). For these cancers, high levels of estrogen (and this includes xenoestrogens, or environmental estrogens) can promote the growth and spread of these tumor cells. Estrogen exerts many of its effects through two different estrogen receptors, estrogen receptor alpha, thought to lead to the proliferation of breast cells, and estrogen receptor beta, thought to oppose or reverse proliferation of breast cells.

Around 20% of hormone receptor positive breast cancer tumors also overexpress a protein known as human epidermal growth factor receptor 2 (“HER2″), which can make this type of breast cancer more aggressive.

15-25% of breast cancer tumors, however, display no hormone receptors or HER2 overexpression, this type is called “triple negative breast cancer” (or “TNBC”). TNBC can be more problematic to treat because all of the therapies developed for hormone receptor positive breast cancer don’t work with this form of breast cancer.

But take heart. Hard-working researchers have been discovering epigenetic nutrients that can downregulate or restore receptors on breast tumor cells, making them more receptive to standard treatments, impairing their ability to receive growth signals, and promoting cancer cell death.

PART 6 – NUTRIENTS THAT ALTER OR RESTORE RECEPTORS ON BREAST CANCER CELLS

Alpha-linolenic acid (ALA) – a fatty acid from flaxseed. When ALA enters the cell membrane, it disrupts protein receptors such as HER2 and estrogen receptors, reducing their activity. [1], [2]

Broussoflavonol B – a phytochemical from the bark of the paper mulberry tree (Broussonetia papyrifera). It downregulates a variant of estrogen receptor (“ER”) alpha known as ERa36, highly expressed in TNBC, and inhibits the growth of ER negative (“ER-“) breast cancer cells. [3]

Caffeine and caffeic acid – from (preferably) organic coffee. Suppresses the growth of ER+ and ER- cells, reduces the risk of TNBC, and sensitizes receptors to Tamoxifen, a commonly prescribed hormonal therapy for ER+ breast cancer, and reduces breast cancer growth. [4], [5]

Curcumin – from the root of the herb turmeric, and also available in the form of supplements (choose the bio-available formulations, usually containing piperine which increases absorption). Curcumin downregulates the expression of ER alpha in ER+/PR+ breast cancer cells. [6]

Cyanadin-3-glucoside – an anthocyanin found in acai, amaranth, blackberries, blackcurrants, cherries, black rice, pistachio nuts, red beans. Downregulates a variant of estrogen receptor alpha known as ERa36, highly expressed in TNBC, and inhibits the growth of ER- breast cancer cells. [7]

DIM – di-indolyl-methane, from cruciferous vegetables, taken in supplement form. DIM activates ER beta target genes. [8]

Genistein – from soybeans. Reactivates ER alpha in ER- breast cancer, restores sensitivity to Tamoxifen in Tamoxifen-resistant cells. [9]

Green Tea Polyphenols – on its own and when combined with sulforaphane, reactivates estrogen receptor alpha in TNBC. [10], [11] In ER+/PR+ breast cancer, EGCG from green tea downregulates ER alpha and inhibits proliferation of these cells. [12]

Melatonin – a hormone produced primarily by the pineal gland, also found in bananas, barley, black rice, tart cherries, ginger, oats, walnuts, and in supplement form. Melatonin selectively neutralizes the effects of circulating estrogen on the breast and interferes with the activation of the estrogen receptor in ER+ breast cancer, thus behaving as a selective estrogen receptor modulator (SERM). It also regulates enzymes involved in the biosynthesis of estrogen in the body, thus behaving as a selective estrogen enzyme modulator (SEEM). [13], [14], [15]
Pomegranate – extracts from pomegranate bind to estrogen receptors and downregulate the estrogen response elements in breast cancer cells. [16]

Sulforaphane – from cruciferous vegetables. Reactivates estrogen receptor expression in ER- breast cancer, inhibits ER alpha in ER+/PR+ metastatic breast cancer cells. [17], [18]

THC (Tetrahydrocannabinol) – from cannabis. In ER+/PR+ breast cancer, THC upregulates ER beta and inhibits the expression ER alpha-regulated genes that promote proliferation. [19]

Please note that this is not an exhaustive list, there will be other nutrients that have this effect as well and as I come across the research, I will add it here.

IMPORTANT NOTE: Please do not attempt to heal cancer using only a few nutrients. Cancer is a complex disease and requires a multi-disciplinary approach to effectively beat it. It is best to work with an oncologist and/or integrative oncologist and/or oncology naturopath and/or functional medicine doctor for the best results.

Epigenetic Factors to Reduce Breast Cancer Risk – Part 5

Epigenetic Factors to Reduce Breast Cancer Risk – Part 5

In this 11-part series of articles, my goal is to empower you with information about the epigenetic factors and phytochemicals that can be put into place in order to help you heal from breast cancer and to reduce your risk of recurrence.

For more information on my personal reasons for putting this information together, see Part 1 of the series.

This article, Part 5 of the series, covers the nutrients that have the ability to change malignant cells back into healthy cells. And isn’t it great to know that even though cells may have become malignant, we still often have a chance to reverse that process by taking the nutrients that encourage them to differentiate back into normal cells. Here are some of the best things that promote differentiation of cells.

PART 5 – CHANGING MALIGNANT CELLS BACK INTO HEALTHY CELLS

a-Tocopheryl Succinate – a form of vitamin E, available in supplement form from health food shops [1]

Conjugated linoleic acid (CLA) – from (preferably) organic grass fed beef, organic butter, full fat (preferably raw) dairy products like cream, milk, yogurt, cheese [2], [3]

Curcumin – from turmeric, also available in supplement form from health food shops (be sure to look for the bio-available versions, usually containing piperine which increases absorption) [4], [5], [6]

Dimethyl sulfoxide (DMSO) – available from most health food shops. Discussed frequently on cancer alternative treatment websites, DMSO research for breast cancer is lacking, however studies in other tumor cells show that it does have the ability to differentiate tumor cells back into healthy cells. Work with a qualified practitioner when using DMSO. [7]

Docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (AA) fatty acids – DHA and EPA are available at most health food shops, while AA is readily available in the diet via vegetable oils, eggs, poultry and meats [8], [9]

Genistein – from chickpeas, kidney beans, quinoa, soybeans [10], [11]

Green Tea [12]

Kaempferol – from amla, Anasazi beans, barley, black beans, black rice, buckwheat bran, chickpeas, chia seeds, flaxseed, green beans, lentils, quinoa, red beans, rice bran [13], [14]

N-acetylcysteine (NAC) – available in supplement form from health food shops [15]

Panax Ginseng – available in supplements or as a tincture from health food shops [16]

Pomegranate [17]

Quercetin – available as a supplement from health food shops or found in adzuki beans, amla, Anasazi beans, apples, apricots, asparagus, barley, berries, black beans, black rice, broccoli, capers, cauliflower, celery, chickpeas, chia seeds, eggplant, gingko biloba, grapes, green beans, green pepper, honey, kale, lentils, lettuce, onions, quinoa, red onions, shallots, tea (black and green), tomatoes [18]

Resveratrol – available in supplement form from health food shops, or found in acai, blueberries, cranberries, dark chocolate, peanuts, peanut butter, pistachio nuts, grapes, black beans, lentils, red wine, white wine [19], [20]

Vitamin D3 – available in supplement form from health food shops (easier to get therapeutic doses this way), or from solar energy on your skin, or from raw milk, salmon, tuna [21], [22], [23]

You will note that the research carried out on some of these isn’t always about breast cancer, but may be for other forms of cancer. When I was able to find research about differentiation of breast cancer cells, I included that, but when it was not, I still felt it was relevant research.

Please note that this is not an exhaustive list, there will be other nutrients that have this effect as well and as I find the research, I will add it here.

IMPORTANT NOTE: Please do not attempt to heal cancer using only a few nutrients. Cancer is a complex process and requires a multi-disciplinary approach. It’s always best to work with an oncologist and/or integrative oncologist and/or oncology naturopath and/or functional medicine doctor to achieve the best results.

Epigenetic Factors to Reduce Breast Cancer Risk – Part 4

Epigenetic Factors to Reduce Breast Cancer Risk – Part 4

My goal in this series of articles is to empower you with information about epigenetic factors that can be utilized to not only reduce your risk of breast cancer, but also to help you heal from breast cancer should you be diagnosed with it.

For more information on my personal reasons for putting this information together, see Part 1 of the series, Epigenetic Factors To Reduce Breast Cancer Risk Part 1.

This article, Part 4 of the series, will cover the phytonutrients that ease or prevent cancer-promoting inflammation. Chronic inflammation in the body is a known risk factor for various cancers, including breast cancer. Eliminating inflammation is a valid strategy for both preventing cancer and for helping to treat it. Science recognizes this and, indeed, many anti-inflammatory cancer drugs are also used to treat inflammatory diseases such as rheumatoid arthritis. [1]

Once a cell becomes malignant, inflammation is a powerful promoter of cancer. Fortunately for us, nature provides us with hundreds of natural anti-inflammatory phytochemicals that work at the gene level to counter inflammation. Here are some of the best ones.

Epigenetic Factors To Reduce Breast Cancer Risk – Part 3

In this series of articles, it is my goal to empower you with information about the epigenetic factors that can be used to not only reduce breast cancer risk, but also to help heal yourself from breast cancer if you have had the misfortune of a diagnosis.

For more information on my personal reasons for putting this information together, see Part 1 of the series.

This article, Part 3 in the series, will cover the nutrients that prevent rapid cell proliferation. Proliferation means a rapid increase in the number or amount of something, and in this case it means cancer cells. Their ability to multiply and rapidly grow is one of the hallmarks of cancer. Many anti-cancer drugs such as chemotherapy target this very thing. Unfortunately, however, these drugs come at a price because they don’t just target rapidly growing cancer cells, they target every cell that is rapidly growing. The beauty of epigenetic nutrients is that they don’t target healthy cells that are rapidly growing – they leave them alone.

PART 3 – NUTRIENTS THAT CAN PREVENT RAPID CELL PROLIFERATION

The nutrients listed below are capable of blocking the continuous multiplication of the cellular replication cycle, thus stopping or slowing cancer cell growth. Few of them have been included in human trials, so we don’t have exact doses, but we can certainly include them as part of a healthy anti-cancer diet.

Please note that this is not an exhaustive list, there are likely many other substances that will prevent rapid cell proliferation. But this will definitely get you started in the right direction!

IMPORTANT NOTE: Please do not attempt to heal cancer using only a few nutrients. Cancer is a complex process and requires a multi-disciplinary approach. It’s always best to work with an oncologist and/or integrative oncologist and/or oncology naturopath and/or functional medicine doctor to achieve the best results.

Epigenetic Factors to Reduce Breast Cancer Risk – Part 2

One of the most fascinating areas of breast cancer research has to be the field of epigenetics and how genes can be expressed differently by using external factors, all without altering the DNA structure of those genes. At first ridiculed by the scientific community, epigenetics is now one of the fastest growing fields of science.

Continuing on from Part 1 in my series of epigenetic factors to reduce breast cancer risk, this article will cover the nutrients that help to prevent damage to DNA.

PART 2 – NUTRIENTS THAT CAN PREVENT DAMAGE TO DNA

As with many other types of cancer, breast cancer generally begins with something happening to alter the DNA function or structure of just one cell. This can trigger that cell to become malignant and a tumor to form, and that process can take months or years, depending upon hundreds of different factors. Other things that are happening when the tumor is forming (to put it in simplest terms) is that a tumor suppressor gene has become silenced or a tumor promoter gene has been activated and allows unchecked cell replication.

The good news is that many nutrients have the ability to prevent and protect against DNA damage. Here is the list of the best 20.

The Top 20 Nutrients that Prevent DNA Damage

1. Curcumin, derived from turmeric [1], [2], [3], [48]

2. Epigallocatechin gallate (EGCG), derived from green tea [4], [5], [6], [47], [48]

3. Coenzyme Q10 [7], [8], [9]

4. Di-indolyl-methane (DIM) [10], [11], [48]

5. Coffee [12], [13]

6. N-acetylcysteine (NAC) [14], [15], [23]

7. Melatonin, a natural hormone [16], [17]

8. Lycopene, derived from tomato, watermelon, guava, papaya [18], [19]

Mind-Body Interventions Also Play A Role in DNA Repair

A recent study [54] carried out by scientists from Coventry University In the UK and Radboud University in the Netherlands demonstrated that mind-body interventions can have an enormous impact on DNA repair. The study analyzed more than 10 years worth of research studies on how mind-body interventions impact DNA and they found that things like yoga, meditation and Tai Chi can actually reverse the deleterious effects that things like stress and other factors might otherwise have on DNA.

The researchers found that people who regularly practice mind-body interventions enjoy a reduction in the production of inflammatory markers. This in turn leads to a reduction and reversal of pro-inflammatory gene expression, thus lowering  the risk of inflammation-related conditions. And as we know, breast cancer is definitely an inflammatory condition. Have a look at the study, it’s reference #54 below.

While this is not an exhaustive list, it will certainly give you a great idea how many natural substances help to protect DNA and reduce breast cancer risk. For more information on the subject of epigenetic factors that reduce breast cancer risk, please see Part 1 of this series of articles which discussed nutrients that can control regulator genes and stay tuned for upcoming articles in this 11-part series.

IMPORTANT NOTE: Please do not attempt to heal cancer using only a few nutrients. Cancer is a complex process and requires a multi-disciplinary approach. It’s always best to work with an oncologist and/or integrative oncologist and/or oncology naturopath and/or functional medicine doctor to achieve the best results.
