the warburg effect: how does it benefit cancer cells?


Our study shows that in regimes of high NAD+ demand, ATP synthase activity constrains NAD+ regeneration by the ETC and fermentation, rather than pyruvate oxidation, is preferred as a supplementary NAD+ producing pathway [10]. But when he observed cancer cells, he saw that they preferred to fuel their growth through glycolysis, a process that involves consuming and breaking down … We find the Warburg effect, high glycolytic metabolism even under normoxic conditions, is represents a metabolic strategy that allow cancer cells to optimally meet energy demands posed by stochastic or fluctuating tumor environments. © 2021 Memorial Sloan Kettering Cancer Center, Gerstner Sloan Kettering Graduate School of Biomedical Sciences, In the Fight against Cancer, the Immune System Can Be a Double-Edged Sword, License to Build: New Theory of Cancer Puts Metabolism at Center. Ferreira, Leonardo M.R. “A lot of companies are developing inhibitors for LDHA, to try to starve cancer cells of nutrients and block tumor growth,” Dr. Li says. The products of this metabolic pathway turn on genes important for T cell function. In fermentation, the last product of glycolysis, pyruvate, is converted into lactate A ketogenic diet is a very high-fat diet that forces your body to burn fat, not carbs, for most of its fuel. We found that treating cells with gramicidin relieved the elevated mitochondrial proton gradient, which ultimately allowed NAD+ regeneration by ETC and proliferation with decreased dependency on fermentation. 2016 Mar;41(3):287. doi: 10.1016/j.tibs.2016.01.004. This phenotype is referred to as “aerobic glycolysis,” because unlike carbohydrate fermentation in response to oxygen limitation, aerobic glycolysis involves high levels of fermentation even when oxygen is abundant. The net effect of this elevated activity is an increase in ATP hydrolysis in the cell, which supplies ADP for ATP synthase to use as a substrate. Mol Cell, Hosios AM, Vander Heiden MG, 2018. Aerobic glycolysis a hallmark of proliferative metabolism found across many kingdoms of life, but is frequently associated with cancer cells, and is known as the Warburg effect in this context. While fermentation allows for NAD+ regeneration uncoupled from ATP synthase, glycolysis is redox neutral and does not net regenerate NAD+. We found that endowing cells with various means to regenerate NAD+ independently of LDH restored proliferation rates in cells in which aerobic glycolysis was suppressed, confirming that fermentation supports proliferation by promoting NAD+ regeneration. Immune cells use a form of metabolism called aerobic glycolysis, aka the Warburg effect. All comments must follow our comment policy. MIT biologists have found a possible explanation for the Warburg effect, first seen in cancer cells in the 1920s and named after Otto Warburg, pictured. Dr. Li says the recent results underscore the need to think about cancer treatment in the context of other cells that might be affected. This phenomenon is observed even in the presence of completely functioning mitochondria and, together, is known as the 'Warburg Effect'. Mitochondrial genome acquisition restores respiratory function and tumorigenic potential of cancer cells without mitochondrial DNA. This is the first time this link has been made. Thus, why increased glucose uptake and glycolysis are also often associated with proliferation remains an open question. That, the authors suggested, would explain the central paradox of the Warburg effect — aerobic glycolysis, or why cancer cells ferment glucose to produce lactate even when oxygen is present. Each of these functions has been hypothesized to be the function of the Warburg Effect. This observation was first published by Otto Heinrich Warburg who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". To do so, we treated cells with a sublethal dose of the ionophore gramicidin, which facilitates the flow of Na+ and K+ ions through the plasma membrane and elicits the cell to engage in elevated Na+/K+ ATPase activity to maintain the Na+/K+ gradient at the plasma membrane. Read more, By This distinction is a subtle but important one, as ETC activity has been showed to be required for tumorigenesis and cell proliferation [16, 17]. The fact that both cancer and immune cells share the same type of metabolism creates some tricky problems for those who would like to treat cancer by interrupting the way it obtains energy or nutrients. Cancer cells rewire their metabolism to promote growth, survival, proliferation, and long-term maintenance. We welcome your comments on this post. Epigenetic mechanisms are increasingly recognized as an important link between the cell’s metabolism — its use of energy and nutrients — and its genetic program. One way to increase the rate of proton flow through ATP synthase is to increase ADP levels. They found cancer cells use fermentation, an inefficient metabolic pathway, because it helps them to generate large quantities of a molecule called NAD+, which they need to synthesize DNA and other important molecules. Increased demand for NAD+ relative to ATP drives aerobic glycolysis. Usually, your body burns fatty acids via the more efficient oxidative phosphorylation pathway and switches over to glycogen at anaerobic intensities but this is not the case with malignancies. Alba Luengo is now at Toran Therapeutics of the Flagship Pioneering Group, and Zhaoqi Li is a postdoc in the Department of Microbiology, Harvard Medical School. Our finding that an elevated proton gradient can function as an inhibitor of the ETC led us to hypothesize that the endogenous mechanism of proton gradient dissipation, ATP synthase, was somehow inadequate in its capacity to relieve this thermodynamic block on the ETC. Walburg hypothesized that cancer cells produced energy through anaerobic respiration He discovered that cancer cells were more dependent on glycolysis for the generation of ATP. Please do not call your doctor about getting vaccinated. One proposed explanation for the phenotype is that increased glucose consumption provides important biosynthetic precursors for anabolic reactions branching from glycolysis, including pathways that produce lipids, nucleosides, or proteins. Cancer cells rewire their metabolism to promote growth, survival, proliferation, and long-term maintenance. The products of this metabolic pathway turn on genes important for T cell function. His lab has already filed a provisional patent on this idea. We need to talk about the Warburg effect. Dr. Otto Warburg received the Nobel prize in 1931 for the discovery that unlike all other cells in the human body, cancer cells do not breathe oxygen. Dev Cell, Pfeiffer T, Schuster S, Bonhoeffer S, 2001. Given that our experiments were performed in normoxia, we faced an unanticipated question: why is the ETC inadequate to maintain NAD+ homeostasis in some rapidly proliferating cells? The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria. New research by scientists at the Sloan Kettering Institute finds a surprising link between metabolism and gene expression in T cells, raising implications for the treatment of cancer and autoimmune diseases. However, these results were surprising since the mitochondrial electron transport chain (ETC) can regenerate NAD+ when oxygen is available. Several perplexing studies have found evidence that futile metabolic cycles can promote cell proliferation. Cancer cells largely exploit these factors to thrive and resist therapies. The ETC does not function in isolation. This research was performed at the Koch Institute for Integrative Cancer Research at MIT, where Matt Vander Heiden is Associate Director. Other models have suggested that aerobic glycolysis optimizes for ATP production [5,6], or results from molecular crowding [7]. Genetic suppression of PDKs has been shown to slow cancer cell growth in culture and in tumors [8,9],  and we used PDK inhibition to study the metabolic underpinnings of how aerobic glycolysis supports proliferation [10]. These experiments led us to conclude that because oxidative phosphorylation is coupled and generates NAD+ and ATP at a fixed stoichiometry, a failure to hydrolyze ATP limits ATP synthase activity and constrains NAD+ production by the mitochondrial ETC. Nature, McFate T, Mohyeldin A, Lu H, Thakar J, Henriques J, Halim ND, Wu H, Schell MJ, Tsang TM, Teahan O, Zhou S, Califano JA, Jeoung NH, Harris RA, Verma A, 2008. A cell with abundant nutrients, for instance, may use epigenetic changes to turn on genes for cell division or some other resource-intensive task, thus ensuring that the cell’s genetic program matches its nutrient and energy capacity. Cell, Naguib A, Mathew G, Reczek CR, Watrud K, Ambrico A, Herzka T, Salas IC, Lee MF, El-Amine N, Zheng W, Di Francesco ME, Marszalek JR, Pappin DJ, Chandel NS, Trotman LC, 2018. Liberti MV, Locasale JW, 2016. Together, this body of evidence indicates that tumor cells can communicate with cells in the immune system to support protumor immunity. Amino Acids Rather than Glucose Account for the Majority of Cell Mass in Proliferating Mammalian Cells. Otto Warburg was a German physiologist and medical doctor who won the Nobel Prize for his "discovery of the nature and mode of action of the respiratory enzyme."

The net effect of this elevated activity is an increase in ATP hydrolysis in the cell, which supplies ADP for ATP synthase to use as a substrate. The most surprising find was what effect this shift in metabolism has on gene expression — the turning on and off of genes. Mitochondrial metabolism and ROS generation are essential for Kras-mediated tumorigenicity. It is likely that the Warburg Effect provides an overall benefit that supports a tumor microenvironment conducive to cancer cell proliferation. What drives aerobic glycolysis, and why it is associated with proliferation, has been a long-standing question [2,3]. Nat Cell Biol, Birsoy K, Wang T, Chen WW, Freinkman E, Abu-Remaileh M, Sabatini DM, 2015. The ‘Warburg Effect’, as it is known, tells us that cancer cells prefer using glucose (i.e., “sugar”) to generate energy, even if there’s enough oxygen available to perform cellular respiration. A definitive explanation for why aerobic glycolysis is associated with cell growth has been lacking and is an area of active investigation. It turns out that cancer cells cannot survive in … The common feature of this altered metabolism is the increased glucose uptake and fermentation of glucose to lactate. Cancer cells and immune cells have something very important in common: They both use a form of metabolism called aerobic glycolysis — also known as the Warburg effect — to acquire nutrients and energy. 1. In the 1920s, Otto Warburg and colleagues observed that tumors were taking up enormous amounts of glucose compared to what was seen in the surrounding tissue. Researchers are trying to learn if it may also help starve cancer cells. Aspartate is an endogenous metabolic limitation for tumour growth. Histone acetylation is what’s called an epigenetic modification — a change in how DNA is packaged in a chromosome that influences whether genes are expressed. Proliferating cells require ATP to meet increased demand for biomass synthesis, and yet aerobic glycolysis is less efficient for ATP production than oxidative metabolism. Epub 2016 Feb 11. The body’s main immune fighters are called T cells. The Warburg Effect: What Turns T Cells On? The Warburg Effect is defined as an increase in the rate of glucose uptake and preferential production of lactate, even in the presence of oxygen. The Warburg Effect refers to the fact that cancer cells, somewhat counter intuitively, prefers fermentation as a source of energy rather than the more efficient mitochondrial pathway of oxidative phosphorylation (OxPhos). 2004; 41(3): 211-18. Connecting co-stimulation to this metabolic reprogramming is a fundamentally new way to think about T cell regulation. Warburg, O, 1924. Link to PubMed. In this review, we report and discuss the potential therapeutic benefit of disrupting the major Myc/Hypoxia-induced metabolic pathway, also known as fermentative glycolysis or "Warburg effect", in aggressive cancer cell lines. by Alba Luengo, Zhaoqi Li, and Matthew Vander Heiden. Pyruvate dehydrogenase complex activity controls metabolic and malignant phenotype in cancer cells. Immune cells have a vital job to perform in the body. Molecular crowding defines a common origin for the Warburg effect in proliferating cells and the lactate threshold in muscle physiology. It is likely that the Warburg Effect provides an overall benefit that supports a tumor microenvironment conducive to cancer cell proliferation. PDH is negatively regulated by the pyruvate dehydrogenase kinases [PDK], and PDK inhibition suppresses aerobic glycolysis by promoting oxidation of glucose carbons in the TCA cycle at the expense of fermentation. Where Dr. Li thinks such inhibitors might be more useful is in treating autoimmune diseases, in which the immune system attacks normal tissues. We will contact you directly. Pyruvate oxidation requires the pyruvate dehydrogenase complex (PDH), which facilitates the entry of pyruvate carbons into the TCA cycle. This is the first time this link has been made. Matthew Tontonoz These proposals together conclude that the Warburg Effect supports a metabolic environment. The Warburg Effect. Nearly a century ago, Otto Warburg discovered that tumors consume tremendous amounts of glucose relative to most non-transformed tissues, and that the majority of glucose consumed by tumors is fermented to lactate, rather than oxidized in pathways that require respiration [1]. Aerobic glycolysis is best characterized by a shift of pyruvate carbons away from the TCA cycle and towards fermentation, rather than an upregulation of glycolysis at the expense of oxidative phosphorylation.

Trends in Biochemical Science. This phenomenon is observed even in the presence of completely functioning mitochondria and, together, is known as the 'Warburg Effect'. When both these wires are tripped, the cells begin a vigorous program of growth and differentiation, sucking up buckets of glucose in the process. Trends Biochem Sci, DeBerardinis RJ, Chandel N, 2020. Naturwissenschaften doi:10.1007/bf01504608. "The Warburg Effect is misunderstood because it doesn't make sense that a cell would ferment glucose when it could get much more energy by oxidizing it. And when they blocked the enzyme that controls histone acetylation, the gene could not be turned on. Cancer cells and immune cells have something very important in common: They both use a form of metabolism called aerobic glycolysis — also known as the Warburg effect — to … We discussed this in our previous post.. “It shows us how immune cells rewire their metabolic pathways to fit their appropriate function.”. Abbreviations: ROS, reactive oxygen species; TCA, tricarboxylic acid cycle. MIT biologists have found a possible explanation for the Warburg effect, first seen in cancer cells in the 1920s. Monday, November 7, 2016, Scientists at the Sloan Kettering Institute are learning what makes T cells hum. “Connecting co-stimulation to this metabolic reprogramming is a fundamentally new way to think about T cell regulation,” Dr. Li says. The redox requirements of proliferating mammalian cells. But a new paper published in the journal Science by researchers at the Sloan Kettering Institute (SKI) adds an intriguing new twist to what advantages the Warburg effect provides to immune cells — it helps to turn them on. Trends Biochem Sci. MSK is now offering COVID-19 vaccine to patients age 65 and over who live in New York State and are in active treatment with MSK on or after 1/1/19. The common feature of this altered metabolism is the increased glucose uptake and fermentation of glucose to lactate. We found that treating cells with gramicidin relieved the elevated mitochondrial proton gradient, which ultimately allowed NAD+ regeneration by ETC and proliferation with decreased dependency on fermentation. Sci 41, 211–218. Figure 2. Proliferating cells have high requirements for NAD+, as this cofactor is needed to catabolize reduced nutrients and to synthesize oxidized biomolecules. But this is the first time that anyone has shown a link between this specific form of metabolism and this exact epigenetic mechanism. In tumors and other proliferating or developing cells, the rate of glucose uptake dramatically increases and lactate is produced, even in the presence of oxygen and fully functioning mitochondria. The Warburg Effect has been documented for over 90 years. In normal tissues, cells may either use OxPhos which generates 36 ATP or anaerobic glycolysis which gives you 2 ATP. This process breaks down glucose sugar into lactate in the cell’s watery cytoplasm without using oxygen or mitochondria, the cell’s so-called power plants. An Overview of Warburg Effect. This process, known as the Warburg Effect, has been studied extensively ( Figure 1 ). The ER UDPase ENTPD5 promotes protein N-glycosylation, the Warburg effect, and proliferation in the PTEN pathway. The Warburg effect, at its simplest, is a series of metabolic changes that are encountered in cells trying to proliferate rapidly. Increased glucose uptake permits higher production of the reducing equivalent NADPH by the oxidative branch of the pentose phosphate pathway, and fermentation involves regeneration of the oxidizing equivalent NAD+ via the action of lactate dehydrogenase (LDH). This metabolic characteristic of cancer cells is termed as the Warburg effect. Cancer cells rewire their metabolism to promote growth, survival, proliferation, and long-term maintenance. The Warburg Effect refers to how cancer cells prefer burning glucose via glycolysis even in aerobic conditions. The common feature of this altered metabolism is the increased glucose uptake and fermentation of glucose to lactate. We wondered whether PDK inhibition could cause the proton gradient to become too large, causing ETC to be thermodynamically “product inhibited.” We found that dissipating the proton gradient increased ETC activity, NAD+ regeneration and proliferation, suggesting that ETC was indeed constrained by the proton gradient when aerobic glycolysis was suppressed. It is part of a series of reactions collectively known as oxidative phosphorylation, whereby the transport of electrons through the ETC generates a proton gradient across the inner mitochondrial membrane. J Biol Chem, Sullivan LB, Luengo A, Danai LV, Bush LN, Diehl FF, Hosios AM, Lau AN, Elmiligy S, Malstrom S, Lewis CA, Vander Heiden MG, 2018. (2017). Nevertheless, our model to explain why many proliferating cells engage in aerobic glycolysis is consistent with other observations in cancer. An Essential Role of the Mitochondrial Electron Transport Chain in Cell Proliferation Is to Enable Aspartate Synthesis. Overflow metabolism in Escherichia coli results from efficient proteome allocation. The Warburg Effect: How Does it Benefit Cancer Cells? The Warburg Effect: How Does it Benefit Cancer Cells? From radiation therapy to clinical trials to check-ins with your doctor, your care is made as convenient as possible. - "The Warburg Effect: How Does it Benefit Cancer Cells?" Despite this intense interest, the function of the Warburg Effect remains unclear. Dr. Li and colleagues, including SKI postdoctoral fellows Min Peng and Na Yin, discovered that the metabolites (breakdown products) of aerobic glycolysis participate in a process called histone acetylation, in which chemical tags called acetyl groups are attached to the proteins around which DNA is spooled in a chromosome. Since the late 1980s, immunologists have known that T cells require two signals to activate them — one through the T cell receptor itself, and one through a molecule called CD28. Nature, Vazquez A, Oltvai ZN, 2011.

For example, cancer cells that do not express the tumor suppressor PTEN upregulate enzymes promoting ATP wasting [14], and elevated ATP has been shown to impair tumor growth [15]. However, our data suggests that ATP is not necessary limiting for proliferation, and that excess ATP can instead impose an upper limit on the oxidative capacity of mitochondria. Together, this body of evidence indicates that tumor cells can communicate with cells in the immune system to support pro-tumor immunity. Therefore, aerobic glycolysis reflects a metabolic state in which the demand for NAD+ for oxidation reaction supersedes the cellular demand for ATP. Furthermore, others have proposed that aerobic glycolysis is a tradeoff to support biosynthesis [34,35,62]. Mitochondrial Complex I Inhibitors Expose a Vulnerability for Selective Killing of Pten-Null Cells. Immune cells use a form of metabolism called aerobic glycolysis, aka the Warburg effect. They must recognize dangerous invaders or cancer and then proliferate rapidly to respond to and contain the threat.

Alba Luengo PhD, Zhaoqi Li PhD, and Matt Vander Heiden PhD. Trends Biochem. We determined that suppressing fermentation by PDK inhibition decreased capacity of cells to produce the cofactor NAD+, a product of the LDH reaction. The metabolic fate of pyruvate determines the extent to which cells engage in aerobic glycolysis. In eukaryotic cells, the potential energy stored in the mitochondrial proton gradient is harnessed by ATP synthase to phosphorylate ADP to make ATP. Link to article. Cell, Fang M, Shen Z, Huang S, Zhao L, Chen S, Mak TW, Wang X, 2010. Scientists think cells resort to this relatively inefficient way of doing business for two main reasons: It provides a quick burst of usable energy and — perhaps even more important — gives the cells the building blocks needed to churn out more copies of themselves. “I think people are starting to appreciate that when it comes to cancer treatment, we need to think more broadly, not just about tumor cells but about the tumor environment and the immune system as well.”. NAD+ is a critical electron acceptor required in many cellular processes and to synthesize oxidized biomass molecules, including lipids, nucleotides, and some amino acids, including aspartate [11-13]. The increased amount of this enzyme, called lactate dehydrogenase, shifts the cell’s metabolism toward the Warburg effect. Cancer Metabolism: The Warburg Effect … To this, we call ‘aerobic fermentation’ or ‘aerobic glycolysis’. Pyruvate is the end-product of glycolysis and lies at the intersection of glycolysis in the cytosol and the tricarboxylic acid (TCA) cycle in the mitochondria. “But what our results suggest is that you can’t do this without also shutting off the antitumor immune response.”. But as SKI immunologist Ming Li and his colleagues now show, they also dramatically increase their production of an enzyme that switches on aerobic glycolysis. January 13, 2021, In oncology, the Warburg effect is a form of modified cellular metabolism found in cancer cells, which tend to favor a specialised fermentation over the aerobic respiration pathway that most other cells of the body prefer. Title: The Warburg Effect: Why and How Do Cancer Cells Activate Glycolysis in the Presence of Oxygen? PLoS One, Kaplon J, Zheng L, Meissl K, Chaneton B, Selivanov VA, Mackay G, van der Burg SH, Verdegaal EM, Cascante M, Shlomi T, Gottlieb E, Peeper DS, 2013. The Warburg Effect has been documented for over 90 years and extensively studied over the past 10 years, with thousands of papers reporting to have established either its causes or its functions. The finding that insufficient ATP synthase activity can restrict NAD+ regeneration could potentially explain why pathways that promote ATP consumption could also promote proliferation. In the case of permitted digital reproduction, please credit the National Cancer Institute as the source and link to the original NCI product using the original product's title; e.g., “New Clarity on the Warburg Effect was originally published by the National Cancer Institute.”. Aerobic glycolysis is an inefficient means of generating ATP when considering yield per glucose molecule. (Source: National Institute of Allergy and Infectious Diseases, National Institutes of Health). Another explanation that has been put forth is that aerobic glycolysis facilitates production of electron carriers required as cofactors for redox reaction in cells. Indeed, the majority of the biomass of proliferating cells is derived from amino acids, rather than glucose [4]. Science, Basan M, Hui S, Okano H, Zhang Z, Shen Y, Williamson JR, Hwa T, 2015. Cancer cells are anaerobic, which means that they derive their energy without needing oxygen. The Warburg Effect: How Does It Benefit Cancer Cells? When the team knocked out the LDHA enzyme, preventing aerobic glycolysis from occurring, they found that the interferon gamma gene was turned off. EDITORIALIn the 1920s, the biochemist Otto Warburg observed that, unlike normal cells, cancer cells catabolize glucose into lactate under aerobic conditions (hence the name ‘The Warburg Effect’ or aerobic glycolysis) (Warburg et al., 1927).
