This text was beforehand printed December 8, 2019, and has been up to date with new data.
Thomas Seyfried, Ph.D., professor within the biology division at Boston Faculty, is a number one professional and researcher within the area of most cancers metabolism and dietary ketosis. His e-book, “Most cancers as a Metabolic Illness: On the Origin, Administration and Prevention of Most cancers” is a foundational textbook on this subject, and in August 2016, he obtained the Mercola.com Recreation Changer Award for his work.
Right here, we talk about the mechanisms of most cancers and the affect of mitochondrial operate, which performs a vital position within the improvement and remedy of this illness. His landmark cancer theory is available as a free PDF.
Lots of his views at the moment are encapsulated in his most paper,1 “Mitochondrial Substrate-Stage Phosphorylation as Vitality Supply for Glioblastoma: Overview and Speculation,” printed on-line December 27, 2018. He is additionally printed a variety of different papers2,3,4 on the metabolic underpinnings of most cancers.
“The paper … is a evaluate and speculation paper figuring out the lacking hyperlink in Otto Warburg’s central idea,” Seyfried explains. “[Warburg] outlined the origin of most cancers very precisely again within the Nineteen Twenties, ’30s, ’40s and ’50s in his work in Germany. Principally, he argued and supplied information displaying that every one most cancers cells, no matter tissue origin, had been fermenters. They fermented lactic acid from glucose as a substrate.
Even within the presence of oxygen, these cells had been fermenting. That is clearly a defect in oxidative phosphorylation. The issue is that for many years, folks mentioned Warburg was unsuitable — primarily as a result of we see a whole lot of most cancers cells take up oxygen and make adenosine triphosphate (ATP) from throughout the mitochondria … Individuals started to query, ‘If most cancers cells have regular respiration, why would they wish to use glucose as a fermentable gasoline?’
The entire idea grew to become distorted … The most cancers cells merely select to ferment quite than respire. Now, in fact, in case you look beneath the electron microscope at majority of cancers, you may see that the mitochondria are faulty in a variety of other ways. Their constructions are irregular. The numbers are irregular. There are a lot of abnormalities of mitochondria seen immediately beneath electron microscopy. Clearly, Warburg was not unsuitable.”
Why Biopsies Are Dangerous
Earlier than we delve into the meat of how most cancers really happens it will be good to evaluate a diagnostic technique that just about all of us are provided when confronted with a most cancers analysis. It’s vital to grasp that this will not be your finest technique and that for a lot of it will be sensible to keep away from the biopsy.
Seyfried warns in opposition to doing biopsies, as this process may very well trigger the most cancers to unfold. A tumor is mainly a gaggle of proliferating cells in a selected a part of your physique. For functions of analysis, a small biopsy pattern will usually be taken to establish whether or not the tumor is benign or malignant.
The issue is that whenever you stab into the most cancers microenvironment to take away part of the tissue, it creates a wound in that microenvironment that in flip elicits the invasion by macrophages and different immune cells.
If you have already got an acidic microenvironment, you run the danger of inflicting a fusion hybridization occasion in that microenvironment between your macrophages and most cancers stem cells (as mentioned under). This might flip a doubtlessly benign state of affairs right into a malignant one, and if the tumor is malignant, stabbing into it may make a foul state of affairs worse.
“The query is, what’s the worth of doing a biopsy within the first place? We take biopsies of breast tissue to get a genomic readout of the completely different sorts of mutations that may be within the cells. Now, if most cancers just isn’t a genetic illness and the mutations are largely irrelevant, then it is mindless to do this within the first place. If the tumor is benign, why would you wish to stab it? If the tumor is malignant, why would you ever wish to stab it?
I got here to this view by studying so many articles within the literature primarily based on mind most cancers, breast most cancers, colon most cancers, liver most cancers displaying how needle biopsies have led to the dissemination of those tumor cells, placing these folks in danger for metastatic most cancers and loss of life,” Seyfried says.
In metabolic remedy you wouldn’t contact the tumor; you wouldn’t disturb the microenvironment. By leaving it alone, you permit the tumor to shrink and go away.
“Whenever you begin to have a look at this as a organic drawback, lots of the issues that we do in most cancers make no sense. We have now, in mind most cancers, folks say, ‘You might have a really low-grade tumor. Let’s go in and get it out.’ What occurs is you go in and get it out, after which the next yr it turns right into a glioblastoma.
How did that occur? Properly, you disturbed the microenvironment. You allowed these cells which can be marginally aggressive to develop into extremely aggressive. Then you definately result in the demise of the affected person,” Seyfried says.
“That occurs considerably as a result of it is referred to as secondary glioblastoma arising from therapeutic try and handle a low-grade tumor. The identical factor can occur with all these completely different organs. You stab breast tumors, you stab colon tumors, you run the danger of spreading the cells …
My argument is the next: If the affected person has a lump, whether or not it is within the breast, within the colon, lung or wherever or a lesion of some type, that ought to be the cue to do metabolic remedy.
Do metabolic remedy first. In all chance, it can shrink down and develop into much less aggressive. Then the choice turns into, ‘Ought to we debulk fully quite than performing some type of a biopsy?’ We wish to scale back the danger, as a result of if we are able to catch the entire tumor fully, then we do not run the danger of spreading it …
In our process, you carry the physique again into a really excessive state of metabolic stability, and then you definately strategically go and degrade the tumors slowly with out harming the remainder of the physique.
Radiation, chemo and the methods that we’re utilizing immediately do not do that. They’re primarily based on the gene idea of most cancers that genetic mutations are inflicting the cell cycle to develop uncontrolled. Properly, this isn’t the case. Once more, a whole lot of these poisonous procedures must be rethought, reanalyzed in my thoughts.”
Fixing the Warburg Principle’s Dilemma
In biology, construction determines operate. That is an evolutionarily conserved idea. So, how can mitochondria be structurally irregular in tissue, but have regular respiration? As Seyfried notes, this does not make sense. Confusion has arisen partly as a result of many examine most cancers in tradition, and “make profound statements and feedback concerning what occurs in tradition,” Seyfried says.
“Should you take a look at most cancers cells in tradition, a lot of them do absorb oxygen and make ATP, however on the identical time, they’re fermenting. This was the conundrum. They referred to as it the Warburg Impact. They’re fermenting, however many individuals on the identical time thought their respiration was regular.
This was the primary drawback with Warburg’s idea. However Warburg clearly mentioned in his papers [that] it isn’t the truth that they absorb oxygen; it is how a lot ATP they will generate from oxidative phosphorylation, which is the conventional respiratory capability of the mitochondria.”
As defined by Seyfried, in case you measure ATP and take a look at oxygen consumption in tumor cells, it seems they’re making ATP and taking in oxygen, due to this fact, their respiration is assumed to be regular. Nevertheless, whenever you take a look at the tissues in most cancers sufferers, the mitochondria are irregular.
“What I and Dr. Christos Chinopoulos from Semmelweis College in Budapest, Hungary, who’s the world-leading professional on mitochondrial physiology and biochemistry … realized [was] that the mitochondria of tumor cells are literally fermenting amino acids, glutamine particularly. They are not breathing. They’re fermenting another gasoline, which is glutamine,” Seyfried says.
Warburg’s Most cancers Principle Proves Right
With this understanding, Warburg’s idea might be confirmed right — most cancers arises from injury to the mitochondria’s means to provide vitality via respiration of their electron transport chain.
The compensatory fermentation includes not solely lactic acid fermentation, but additionally succinic acid fermentation utilizing glutamine as a fermentable gasoline. It has been recognized for many years that glutamine is a primary gasoline for a lot of completely different sorts of cancers, however most individuals thought it was being respired, not fermented.
Seyfried and Chinopoulos’ discovery confirms that most cancers cells actually have broken respiration, and to outlive, the most cancers cells should use fermentation. The 2 most out there fermentable fuels within the most cancers microenvironment are glucose and glutamine. Therefore, focusing on glucose and glutamine is a vital element of most cancers remedy.
With out glucose and glutamine, the most cancers cells will starve, as they can not use ketones. The best strategy to most cancers then is to carry sufferers into therapeutic ketosis, after which strategically goal the provision of glucose and glutamine.
“Principally, what we’re saying [is] that mitochondrial substrate-level phosphorylation is a non-oxidative metabolism mechanism contained in the mitochondria that may generate vital quantities of vitality with out oxidative phosphorylation,” Seyfried says.
Genetic Mutations Are Not the Explanation for Most cancers
In keeping with Seyfried, mitochondrial dysfunction is on the coronary heart of almost each sort of most cancers. Sadly, few oncologists have this understanding and plenty of nonetheless imagine most cancers is the results of genetic defects. Nevertheless, nuclear switch experiments clearly present most cancers can’t be a genetic illness.
“There’s been no rational scientific argument that I’ve seen, to discredit the multitude of proof displaying that the [genetic] mutations should not the drivers however the results [of mitochondrial dysfunction],” Seyfried says.
“As a matter of truth, there’s new data now the place individuals are discovering so-called genetic drivers of most cancers expressed and current in regular cells, regular pores and skin and in addition esophagus … That is one other [issue] — the way you get these so-called driver mutations in regular tissues. We’re additionally discovering some cancers that don’t have any mutations, but, they’re fermenting and rising uncontrolled.
There are a variety of recent observations popping out that problem the idea that most cancers is a genetic illness. And when you notice that it isn’t a genetic illness, then it’s a must to significantly query the vast majority of therapies getting used to handle the illness. This [helps] clarify [why] we now have 1,600 folks a day dying from most cancers in the US.
Why do we now have such an epidemic of struggling and loss of life when we now have been finding out this illness for many years? Properly, in case you take a look at the huge quantities of scientific papers being written on most cancers, you may usually discover that they are structured round gene defects.
What I am saying is that if most cancers just isn’t a genetic illness and the mutations are downstream epiphenomena, why would the sector proceed to concentrate on issues which can be principally irrelevant to the character of the illness? What I am saying may be very devastating, as a result of I am telling the vast majority of the folks within the area that they are mainly losing their time …
I believe we are able to drop the loss of life charge of this illness by about 50% in 10 years if most cancers is handled as a mitochondrial metabolic illness, focusing on fermentable fuels quite than utilizing poisonous therapies which can be targeted on downstream results.
Radiation is designed to cease DNA replication. DNA replication requires vitality. Should you pull the plug on their fermentable fuels, they don’t seem to be going to have the ability to replicate anyway … The entire issues that we’re doing to deal with most cancers is mainly approaching the illness from a misunderstanding of the biology …
We all know viruses may cause most cancers. We all know radiation causes most cancers. We all know carcinogens trigger most cancers. We all know intermittent hypoxia causes most cancers. We all know systemic irritation causes most cancers. We all know simply getting older places you in danger for extra most cancers.
We all know there are inherited mutations within the genome that may trigger most cancers. However how are all these items linked via a typical pathophysiological mechanism? The frequent pathophysiological mechanism is broken via the construction and performance of the mitochondria.
Each one of many points … together with inherited mutations, injury the respiration of a selected inhabitants of cells in a tissue. You take a look at the breast most cancers gene (BRCA 1), for instance. Individuals will say, ‘Most cancers should be a genetic illness since you inherit a mutation that causes the illness.’
You solely get the illness if that mutation disrupts the operate of the mitochondria. Fifty p.c of girls who carry the mutation by no means get most cancers or breast most cancers as a result of the mutation, for some cause, didn’t injury the mitochondria in that particular person.”
So, to summarize, the true origin of most cancers is injury to the respiratory operate of the mitochondria, triggering compensatory fermentation, which is run by oncogenes. Oncogenes play a task by facilitating the entry of glucose and glutamine into the cell to switch oxidative phosphorylation.
Why and How Most cancers Spreads
Seyfried additionally has a really completely different view on the biology of metastasis (the unfold of most cancers). He explains:
“We have checked out most cancers stem cells in a variety of our preclinical fashions … These guys develop like loopy in place. The tumor simply retains increasing, but it surely does not unfold. It does not unfold into the bloodstream or metastasize to varied organs.
We found a really uncommon most cancers 20 years in the past. It took us 10 to fifteen years to determine what it was. You possibly can put a number of of those cells anyplace within the mouse’s physique and inside three to 4 weeks, this mouse is stuffed with metastatic most cancers. It made the duvet of the Worldwide Journal of Most cancers, once we printed this again in 2008, however we had labored on the issue for years.
We could not determine what it was that made these cells so extremely metastatic. We came upon that after we recognized the biology of the cell, it turned out [it has] many traits in frequent with the macrophage, which is likely one of the strongest immune cells in our physique.
We mentioned, ‘Wow. Is that this distinctive solely to this sort of cell or do metastatic cancers in people additionally categorical traits of macrophages?’ We regarded and we discovered that nearly each main most cancers that metastasizes has traits of macrophages. Then we mentioned, ‘Properly, how may this presumably occur? Is it coming from the macrophage?’
A lot of scientists … have all clearly proven that there’s some fusion hybridization character happening. In different phrases, macrophages, our wound-healing cells, they arrive right into a microenvironment the place you would possibly discover many proliferating neoplastic stem cells, however they do not have the capability to metastasize.
It is solely when the macrophages fuse with these stem cells that you’ve got a dysregulated vitality metabolism coming on this hybrid cell. This hybrid cell now has traits of each stem cells and macrophages.
The stem cell just isn’t genetically outfitted to enter and exit tissue. The macrophage, as a standard cell of your physique, is genetically outfitted to enter and exit tissue and reside within the bloodstream. They’re very strongly immunosuppressive. These are all traits of metastatic most cancers.”
Metastatic Most cancers Is a Hybrid Cell Mixture
In keeping with Seyfried, metastatic most cancers cells are primarily a hybrid, a mixture of an immune system cell and a dysregulated stem cell, the latter of which may originate from a disorganized epithelial cell or one thing comparable. Briefly, it is a hybrid cell with macrophage traits.
Macrophages are important for wound therapeutic and a part of our main protection system in opposition to bacterial infections. They reside each within the bloodstream and in tissues, and may go anyplace within the physique. When an damage or an infection happens, they instantly transfer in to guard the tissue.
“The metastatic most cancers cell has a lot of those self same properties,” Seyfried explains, “However the vitality and the operate of the cell is totally dysregulated, so it proliferates like loopy however has the capability to maneuver and unfold via the physique, so it is a corrupted macrophage. We name it a rogue macrophage.”
Like macrophages, metastatic most cancers cells also can survive in hypoxic environments, which is why most angiogenic therapies are ineffective in opposition to metastatic most cancers.
So, what do these metastatic hybrid cells have to survive? Each macrophages and immune cells are main glutamine customers, and in accordance with Seyfried, you may successfully kill metastatic cells by focusing on glutamine.
Typical Most cancers Remedies Are Unnecessarily Lethal
Nevertheless, it should be finished in such a manner in order to not hurt the conventional macrophages and the conventional immune cells. In different phrases, it should be strategic. For that reason, Seyfried developed a “press-pulse remedy” for most cancers, which permits the affected person to keep up regular immune system operate, whereas on the identical time focusing on the corrupted immune cells — the macrophage fusion hybrid metastatic cells — in addition to irritation.
“The therapies we’re utilizing to aim to kill these [metastatic] cells put us in danger for having the cells survive and kill us. You possibly can management these cells for a brief time period, however they will hunker down and enter into some type of a barely dormant state, however they reappear.
Individuals say, ‘Oh, these tumor cells are so nifty and good they will come again at you.’ The issue is you have by no means actually challenged them on their very existence, which is that they rely on fermentation to outlive. Should you do not goal their fermentation, they are going to proceed to outlive and are available again at you.
Most of the therapies that we use — radiation, chemo and a few of these different procedures — should not actually going after the center of the issue. That oftentimes places you in danger for the recurrence of the illness. Your physique is already significantly weakened by the poisonous therapies. And within the battle, you lose. If you’re lucky sufficient to outlive … your physique continues to be beat up.
You might have now put your [body] in danger for different kinds of maladies … Why are we utilizing such poisonous therapies to kill a cell once we know what its weaknesses are? These are the paradigm adjustments that must happen as we transfer into the brand new period of managing most cancers in a logical manner.”
A Strategic Method to Killing Most cancers Cells
To correctly handle most cancers, then, it’s worthwhile to clear up the microenvironment, as a result of the microenvironment will strategically kill cells which can be depending on fermentation whereas enhancing cells that are not. On the identical time, the microenvironment may also scale back irritation.
“You additionally need to be very cautious to not kill your regular and wholesome immune cells, as a result of they want glutamine too,” Seyfried says. “What we discover is that once we strategically assault the tumor this fashion, it seems that our immune cells are paralyzed.
The most cancers cells are killed, however the regular immune cells are paralyzed. They are not dying, they’re simply not doing their job. What we do is we again off the remedy slightly; permit the conventional immune cells to regain their organic capability, decide up useless corpses, heal the microenvironment, after which we go after the most cancers cells once more.
It is a graded response, understanding the biology of the conventional cells and the irregular biology of the tumor cells. This can be a lovely technique. As soon as folks know how one can play one group of cells off one other, and how one can strategically kill one group of cells with out harming the opposite cells, it actually turns into a precision mechanism for eliminating tumor cells with out harming the remainder of the physique.
You do not must be poisoned and irradiated. You simply need to know the best way to use these procedures to strategically kill the cells. Defending regular macrophages is a part of the strategic course of. Killing the corrupted ones is a part of the strategic course of. Once more, it’s a must to put all of those collectively in a really logical path. In any other case, you are not going to get the extent of success that we ought to be getting.”
The Press-Pulse Technique
This technique is what Seyfried calls “press-pulse remedy,” and primarily includes limiting the fermentable fuels — glucose and glutamine — in a cyclical trend to keep away from inflicting injury to regular cells and tissues. Glucose is successfully restricted via a ketogenic weight-reduction plan. Limiting glutamine is barely trickier.
The press-pulse technique was developed from the idea of press-pulse within the area of the paleobiology. A “press” was some persistent stress on populations, killing off giant numbers, however not all the pieces, as a result of some organisms can adapt to emphasize. The “pulse” refers to some catastrophic occasion.
The simultaneous incidence of those two unlikely occasions led to the mass extinction of just about all organisms that existed on the planet. This was a cyclic occasion over many a whole bunch of hundreds of thousands of years. The geological data present proof for this press-pulse extinction phenomenon.
“What we merely did was take that idea and say, ‘Let’s chronically stress the tumor cells.’ They want glucose. You possibly can most likely kill a major variety of tumor cells by simply stressing their glucose. That is the press. The press is other ways to decrease blood sugar. You place that persistent stress on prime of the inhabitants both by restricted ketogenic diets [or] therapeutic fasting. There are a whole lot of ways in which you are able to do this.
Additionally, emotional stress discount. Individuals are freaked out as a result of they’ve most cancers, due to this fact their corticoid steroids are elevated, which elevates blood sugar. Utilizing varied types of stress administration, reasonable train — all of those will decrease blood sugar and contribute to a persistent press and stress on the most cancers cells.
Nevertheless, you are not going to kill all most cancers cells in case you simply take away glucose. As a result of the opposite gasoline that is conserving the beast alive is the glutamine. We have now to pulse, as a result of we will not use a press for glutamine focusing on, as a result of then you are going to kill your regular immune cells or impair them, and they’re wanted for the eventual decision of the illness.
What we will do is we will pulse varied medicine. We do not have a weight-reduction plan system that may goal glutamine. Glutamine is in every single place. It is essentially the most considerable amino acid in your physique … However it’s a must to use [the drugs] very strategically; in any other case they will hurt our regular immune system after which be counterproductive …
I believe that after we perceive how we are able to goal successfully glutamine with out harming our regular immune cells … that is the technique that may make most of those different therapies out of date … It is cost-effective and non-toxic and it’ll work very properly.
However we’re nonetheless on the very starting of this. We have to proceed to develop the doses, timing and scheduling of these medicine which can be handiest in focusing on glutamine that may be finished with out harming the remainder of the cells in our physique.”
