  • 6. Most Humble Acknowledgment Warburg and co-workers showed in the 1920s that, under aerobic conditions, tumor tissues metabolize approximately tenfold more glucose to lactate in a given time than normal tissues, a phenomenon known as the Warburg effect. Otto Heinrich Warburg (1883-1970) Nat Rev Cancer. 2011 May;11(5):325-37. www.drbonci.com 6

  • 8. The key to growth is the introduction of higher dimensions of consciousness into our awareness. ~Lao Tzu~ www.drbonci.com
  • 9. Minding My Own Business www.drbonci.com 9
  • 10. And He Says ... It is well documented that tumorigenicity can be suppressed when cytoplasm from enucleated normal cells is fused with nucleated tumor cells to form cybrids. Seyfried, Thomas (2012-05-17T16:00:00+00:00). Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 5097-5099). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 11. Cybrids contain a single nucleus and mixtures of cytoplasm from two different cells. Seyfried, Thomas (2012-05-17T16:00:00+00:00). Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 5097-5099). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 12. The Secret of Cybrids www.drbonci.com
  • 13. Suppression of Malignant State Israel and Schaeffer In Vitro Cell Dev Biol. 1987;23:627–32. showed that suppression of the malignant state could reach 100% in cybrids containing normal cytoplasm and tumorigenic nuclei. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 51065107). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 14. Nuclei Ain't Nothin' Israel and Schaeffer In Vitro Cell Dev Biol. 1988;24:487–90. also showed that nuclear/cytoplasmic hybrids derived by fusion of cytoplasts from malignant cells (nucleus absent) with karyoplasts from normal cells (nucleus present) produced tumors in 97% of the animals injected. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 51085109). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 15. The Secret of Cybrids www.drbonci.com
  • 16. Whiskey Tango Foxtrot? It is also well documented that nuclei from cancer cells can be reprogrammed to form normal tissues when transplanted into normal cytoplasm despite the continued presence of the tumor-associated genomic defects in the cells of the derived tissues. Seyfried, Thomas (2012-05-17T16:00:00+00:00). Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 5176-5178). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 17. The Secret of Cybrids www.drbonci.com
  • 18. It's About the OxPhos Normal mitochondria ... suppress tumorigenesis because their OxPhos is sufficient for maintaining energy homeostasis. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 52015202). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 19. The Differentiated State Respiration is required for the emergence and maintenance of differentiation, while loss of respiration leads to glycolysis, dedifferentiation, and unbridled proliferation. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 52555258). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 20. Hello! Is anyone listening? Replacement of damaged mitochondria with normal mitochondria, which will produce sufficient energy through respiration, restores the differentiated state. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 52605261). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 21. One More Time … Hello? In rephrasing, normal mitochondrial function maintains the differentiated state thereby suppressing carcinogenesis, whereas dysfunctional mitochondria can enhance dedifferentiation thereby facilitating carcinogenesis. Seyfried, Thomas. Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 52705272). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 22. “Complexity is a strategy used by professional elites to maintain control.” Ian Roberts The Energy Glut: The Politics of Fatness in an Overheating World, 2010. p.90 www.drbonci.com
  • 23. OxPhos = Mature State Thus, establishment of the mitochondrial system and engagement of oxidative metabolism are prerequisites for the differentiation of stem cells into a functional [cardiac] phenotype. Nat Clin Pract Cardiovasc Med. 2007 February; 4(Suppl 1): S60–S67. www.drbonci.com
  • 24. Gylcolysis = Immature State Energy metabolism shifts from glycolysis to OxPhos with differentiation, or from OxPhos to glycolysis with reprogramming to pluripotency. Cell Stem Cell. 2012 Nov 2;11(5):589-95. www.drbonci.com
  • 25. The Warburg Effect The Warburg effect underlies the simultaneous increase in glycolytic rate with a reduced mitochondrial respiratory rate; a kind of mitochondrial dysfunction that is found in tumor metabolic reprogramming pathways. Antioxid Redox Signal. 2012 May 15;16(10):1150-80. www.drbonci.com
  • 26. Crabtree Effect Cancer cells have also been shown to be different from normal cells by reversibly down-regulating their oxygen consumption in response to increases in glucose: the Crabtree effect. PLoS One. 2013; 8(2): e56884. Increasing concentrations of glucose accelerates glycolysis (the breakdown of glucose) which results in the production of appreciable amounts of ATP through substrate-level phosphorylation. This reduces the need of oxidative phosphorylation done by the TCA cycle via the electron transport chain and therefore decreases oxygen consumption. http://en.wikipedia.org/wiki/Crabtree_effect www.drbonci.com
  • 27. Joshua Lederberg, PhD The impediment to real discourse in academic communities is the tendency to proclaim what we know more than what we seek. Joshua Lederberg, PhD Nobel Prize Laureate Physiology and Medicine www.drbonci.com
  • 28. The Gray Scale of Disease If it is true that a completely dysfunctional mitochondrial set results in cancer, then is it possible that a partially or incompletely dysfunctional mitochondrial set could result in any of the wide spectrum of diseases we see associated with genome instability … or “bad” genes? www.drbonci.com
  • 29. Getting Reacquainted The word mitochondrion comes from the Greek μίτος, mitos, i.e. "thread", and χονδρίον, chondrion, i.e. "granule". https://en.wikipedia.org/wiki/Mitochondrion www.drbonci.com
  • 30. Endosymbiotic Theory The mitochondria are the product of a symbiosis between two micro-organisms that occurred about two billion years ago. The nature of the original partner organisms is actively debated, but the progenitor of the mitochondrion is thought to have been an alphaproteobacterium that harboured a complete OxPhos system. Philos Trans R Soc Lond B Biol Sci. 2013 July 19; 368(1622): 20120267. www.drbonci.com
  • 31. Of Mitochondria and Chloroplasts The endosymbiotic theory of mitochondrial origin was substantiated with microbiological evidence by Lynn Margulis in 1967. J Theor Biol. 1967 Mar;14(3):255-74. Andreas Schimper (1883) that chloroplasts closely resembled free-living cyanobacteria. http://en.wikipedia.org/wiki/Endosymbiotic_theory www.drbonci.com
  • 32. Benefits of Symbiosis A single bacterial cell can generate only enough energy to sustain about 10,000 genes. When the host cell acquired multiple oxidative bacteria, the bacterial energy could be pooled to provide the required energy for adding more genes to the host cell’s DNA to create more complex anatomical structures. Philos Trans R Soc Lond B Biol Sci. 2013 July 19; 368(1622): 20120267. www.drbonci.com
  • 33. Genome Expansion By enabling oxidative phosphorylation across a wide area of internal membranes, mitochondrial genes enabled a roughly 200,000-fold rise in genome size compared with bacteria. Nature. 2010 Oct 21;467(7318):929-34. www.drbonci.com
  • 34. Costs of Gene Expression Whereas the energetic cost of possessing genes is trivial (2%), the cost of expressing them as protein (75%) is not and consumes most of the cell’s energy budget. Mitochondria increased the number of proteins that a cell can evolve, inherit and express by four to six orders of magnitude, but this requires mitochondrial DNA. Nature. 2010 Oct 21;467(7318):929-34. www.drbonci.com
  • 35. The Price of Complexity Growth and replication of the nucleus is limited by mitochondrial energy production and thus calorie availability. Mitochondrion. 10(1): 12-31. Without mitochondria, [ cells ] cannot pay the energetic price of complexity. Nature. 2010 Oct 21;467(7318):929-34. www.drbonci.com
  • 36. Mitochondria are of Female Origin The female oocyte (egg cell) will pass on more than 100,000 mitochondria to the next generation; sperm cells typically possess less than 100 mitochondria. Evans, Joseph (2013-02-28). The Secret Life of Mitochondria (Kindle Locations 136-138). Smashwords, Inc.. Kindle Edition. www.drbonci.com
  • 37. What’s the Significance for Us? “Well, it means to find what is the source of your own life, and what is the relationship of your body, your physical form, to this energy that animates it. The body without the energy isn’t alive, is it? So you distinguish in your own life that which is of the body and that which is of energy and consciousness.” Campbell, Joseph; Bill Moyers (2011-05-18). The Power of Myth (p. 211). Knopf Doubleday Publishing Group. Kindle Edition. www.drbonci.com
  • 38. The Giver of Forms “It’s the female as the giver of forms. She is the one who gave life to the forms and she knows where they came from. It is from that which is beyond male and female. It is from that which is beyond being and nonbeing. It both is and is not. It neither is nor is not. It is beyond all categories of thought and the mind.” Campbell, Joseph; Bill Moyers (2011-05-18). The Power of Myth (p. 226). Knopf Doubleday Publishing Group. Kindle Edition. www.drbonci.com
  • 39. A Cellular Yin and Yang Mitochondria is the female energy and giver of forms. Nucleus is the male energy or action and creativity. www.drbonci.com
  • 40. A Cellular Adam and Eve Eve … giver of forms … Adam … consciousness ... www.drbonci.com
  • 41. A Cellular Shiva and Shakti Shakti … mitochondrial … giver of forms Shiva … nuclear … creative consciousness www.drbonci.com
  • 42. Power and Wisdom is a Female Principle in Religion, Myth and Culture. www.drbonci.com
  • 43. "I awoke, only to see the rest of the world was still asleep." Leonardo Davinci www.drbonci.com
  • 44. 15 Pounds of Mitochondria Adults possess approximately 10 million billion mitochondria, which corresponds to approximately 10% of our body weight! Evans, Joseph (2013-02-28). The Secret Life of Mitochondria (Kindle Locations 138-139). Smashwords, Inc.. Kindle Edition. www.drbonci.com
  • 45. Mitochondrial Bioenergetics www.drbonci.com
  • 46. Mitochondrial Microanatomy There are five distinct parts to a mitochondrion. 1. outer mitochondrial membrane 2. intermembrane space (the space between the outer and inner membranes) 3. the inner mitochondrial membrane 4. the cristae space (formed by infoldings of the inner membrane) 5. the matrix (space within the inner membrane) Alberts, Bruce; Alexander Johnson, Julian Lewis, Martin Raff, Keith Roberts, Peter Walter (1994). Molecular Biology of the Cell. New York: Garland Publishing Inc. ISBN 0-8153-3218-1. www.drbonci.com
  • 47. Mitochondrial Outer Membrane The outer mitochondrial membrane contains enzyme systems for glycolysis, cardiolipin and phospholipid synthesis. Carolyn D. Berdanier. Mitochondria in Health and Disease CRC Press, 2005. www.drbonci.com
  • 48. Glycolysis www.drbonci.com
  • 49. Glycolysis Trivia Glycolysis produces its energy 100 times faster than aerobic respiration. Glycolysis is the preferred energy source of rapidly growing cell populations. The early zygote becomes increasingly dependent on glycolytic energy production as development progresses to the blastocyst stage. Int. J. Dev. Biol. 56: 799-808 (2012) www.drbonci.com
  • 50. Mitochondrial Matrix The mitochondrial matrix contains enzyme systems for the Krebs cycle and ketone metabolism. The matrix also anchors the mitochondrial DNA (mtDNA). Carolyn D. Berdanier. Mitochondria in Health and Disease CRC Press, 2005. www.drbonci.com
  • 51. Citric Acid Cycle www.drbonci.com
  • 52. Mitochondrial Inner Membrane The inner mitochondrial membrane contains enzyme systems for partial fatty acid oxidation and the electron transport chain. Carolyn D. Berdanier. Mitochondria in Health and Disease CRC Press, 2005. www.drbonci.com
  • 53. www.drbonci.com
  • 54. NAD+/NADH The mitochondrial NADH is oxidized by the electron transport chain, which pumps protons across a membrane and generates ATP through oxidative phosphorylation. Biochem Soc Trans. 2003 Dec;31(Pt 6):1095105. www.drbonci.com
  • 55. www.drbonci.com

  • 57. www.drbonci.com
  • 58. Coenzyme Q10 CoQ10 functions as an electron carrier from enzyme complex I and enzyme complex II to complex III in this process … a process which also involves menaquinones or Vitamin K2. Science 336, 1306 (2012) www.drbonci.com
  • 59. www.drbonci.com
  • 60. Cytochrome C Cytochrome c carries an electron in the ETC and is also an intermediate in apoptosis, a controlled form of cell death used to kill cells in the process of development or in response to infection or DNA damage. Cell. 1996 Jul 12;86(1):147-57. www.drbonci.com
  • 61. Cardiolipin: Mitochondrial-Specific Lipid Cardiolipin is a complex, mitochondrial-specific phospholipid that regulates numerous enzyme activities, especially those related to OxPhos and coupled respiration. Seyfried, Thomas (2012-05-17T16:00:00+00:00). Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 2125-2129). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 62. Cardiolipin: ETC Caulking Cardiolipin (CL) which represents 20% of membrane phospholipids is necessary for maintaining coupled mitochondria, and defects in CL can produce protein independent uncoupling. Hence, alterations in the content or composition of CL will alter cellular respiration. Seyfried, Thomas (2012-05-17T16:00:00+00:00). Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (Kindle Locations 2125-2129). Wiley Publishing. Kindle Edition. www.drbonci.com
  • 63. www.drbonci.com
  • 64. Mitochondrial Distribution Mitochondria are distributed throughout the cytoplasm in a nonrandom manner by cytoskeleton motors. Cells that are rapidly dividing have mitochondria close to the nucleus and to ribosomes because de novo protein synthesis is highly dependent on the energy provided by ATP. Carolyn D. Berdanier. Mitochondria in Health and Disease CRC Press, 2005. www.drbonci.com
  • 65. Mitochondrial Genome The mitochondrial genome contains 37 genes that encode 13 proteins, 22 transfer RNAs, and 2 ribosomal RNAs. The 13 mitochondrial gene-encoded proteins all instruct cells to produce protein subunits of the enzyme complexes of the oxidative phosphorylation system, which enables mitochondria to act as the powerhouses of our cells. Nature Education 1(1):217; 2008. www.drbonci.com
  • 66. mtDNA Mutations Most pathogenic mitochondrial DNA (mtDNA) mutations induce defects in mitochondrial oxidative phosphorylation (OxPhos). Epigenetics. 2012 Apr;7(4):326-34. www.drbonci.com
  • 67. ROS mtDNA Dysfunction The mitochondrial free radical theory postulates that aging is caused by the toxicity of ROS, initiating a vicious cycle whereby damage to mtDNA and other mitochondrial constituents leads to respiratory chain dysfunction, which in turn leads to increased generation of ROS further facilitating mtDNA damage and thus creating a self-amplifying deterioration. J Intern Med. 2013 June; 273(6): 529–543. www.drbonci.com
  • 68. Reactive Oxygen Species In general, harmful effects of reactive oxygen species on the cell are most often: ● ● ● ● damage of nDNA and mtDNA oxidations of polyunsaturated fatty acids in lipids (lipid peroxidation) oxidations of amino acids in proteins oxidatively inactivate specific enzymes by oxidation of co-factors http://en.wikipedia.org/wiki/Reactive_oxygen_species www.drbonci.com
  • 69. Antioxidant Defenses Antioxidant defenses are also up-regulated in conjunction with OxPhos to offset the effects of increased mitochondrial ROS production. Mitochondrion. 10(1): 12-31. Endogenous, genetically encoded antioxidant systems linked to the Antioxidant Response Elements (AREs) will be discussed in future slides. Exogenous antioxidants will be given passing attention in favor of the more powerful and evolutionary significant endogenous antioxidants. www.drbonci.com
  • 70. Drug-induced Mitochondrial Toxicity Drugs that injure mitochondria usually do so by inhibiting respiratory complexes of the electron chain; inhibiting or uncoupling oxidative phosphorylation; inducing mitochondrial oxidative stress; or inhibiting DNA replication, transcription or translation. It is important to test for mitochondrial toxicity early in drug development as impairment of mitochondrial function can induce various pathological conditions that are life threatening or can increase the progression of existing mitochondrial diseases. Expert Opin Drug Metab Toxicol. 2005 Dec;1(4):655-69. www.drbonci.com
  • 71. NSAID Induced Mitochondrial Toxicity [Mitochondrial toxicity] involves specific biochemical damage of mitochondria and uncoupling the oxidative phosphorylation reaction. Electron microscopic studies show vacuolisation and ballooning of mitochondria within an hour of indomethacin administration which is highly characteristic of uncoupling of oxidative phosphorylation. The consequence of uncoupling is diminished cellular ATP, which alters the intercellular junction, increases intestinal permeability, and releases calcium into cytosol which in turn causes secondary biochemical damage. Gut. 2001 February; 48(2): 163–167. www.drbonci.com
  • 72. Mitochondrial Dysfunction Injury to the mitochondrial electron transport chain (ETC) or mutations of mtDNA leading to mitochondrial dysfunction have recently been suggested as an important factor in the pathogenesis of mitochondrial … a range of other diseases, aging, cancer and a range of other human disorders. human disorders. Epigenetics. 2012 Apr;7(4):326-34. Biochim Biophys Acta. 2010 www.drbonci.com
  • 73. Muscles Common Symptoms: Hypotonia, weakness, cramping, muscle pain, ptosis, and ophthalmoplegia. Despite the subjective weakness, many patients have minimal objective findings, possibly because fatigability is difficult to quantify in a physician’s office. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 74. Fibromyalgia? The etiology is unknown; however, recent studies suggest that mitochondrial dysfunction is involved in the pathophysiology of fibromyalgia. Mitochondrial DNA content (mtDNA/gDNA ratio) was reduced in fibromyalgia patients versus healthy controls (p<0.001). Expression levels of peroxisome proliferator-activated receptor gamma-coactivator 1-alpha was significantly lower in fibromyalgia patients (p<0.001) compared with healthy controls. Antioxid Redox Signal. 2013 Nov 20;19(15):1855-60. www.drbonci.com
  • 75. Brain Common Symptoms: Developmental delay, mental retardation, autism, dementia, seizures, neuropsychiatric disturbances, atypical cerebral palsy, atypical migraines, stroke and stroke-like events. Migraine, dementia, seizures, and strokelike episodes can occur at any stage of the disease, but like myopathy, brain involvement is not required for the diagnosis. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 76. Nerves Common Symptoms: Neuropathic pain and weakness (which may be intermittent), acute and chronic inflammatory demyelinating polyneuropathy, absent deep tendon reflexes, neuropathic gastrointestinal problems (gastroesophageal reflux, constipation, bowel pseudoobstruction), fainting, absent or excessive sweating, and aberrant temperature regulation. Nerve cells and Schwann cells are extremely active metabolically: nerve cells require a tremendous amount of energy to maintain the electrochemical gradient necessary for nerve transmission. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 77. Kidneys Common Symptoms: Proximal renal tubular dysfunction, may result in loss of protein (amino acids), magnesium, phosphorous, calcium, and other electrolytes. The proximal renal tubular cells require an abundant and steady energy supply. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 78. Heart Common Symptoms: Cardiac conduction defects (heart blocks) and cardiomyopathy. The sinoatrial and atrioventricular nodes are the most metabolically active tissues in the body, and the muscular activity of the heart never ceases. Therefore, cardiac conduction defects and cardiomyopathy are complications of mitochondrial dysfunction. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 79. Liver Common Symptoms: Hypoglycemia, gluconeogenic defects, and nonalcoholic liver failure. Maintenance of glucose homeostasis is the most vital moment-to-moment function of the liver. Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com
  • 80. Eye and Ear Common Symptoms: Optic neuropathy and Sensoryneural hearing loss Starting with high-frequency hearing loss, it can progress to total deafness. A number of mtDNA point mutations are associated with an extreme otosensitivity to aminoglycoside antibiotics (streptomycin). Cleve Clin J Med. 2001 Jul;68(7):625-6, 629-42. www.drbonci.com

Hope Springs Eternal A wide range of seemingly unrelated disorders have underlying pathophysiological mechanisms in common, namely reactive oxygen species (ROS) production, the accumulation of mitochondrial DNA (mtDNA) damage, resulting in mitochondrial dysfunction. If in the next 50 years advances in mitochondrial treatments match the immense increase in knowledge about mitochondrial function that has occurred in the last 50 years, mitochondrial diseases and dysfunction will largely be a medical triumph.

The idea that eating little and often is a “good thing” has been driven partly by snack manufacturers and faddish diet books, but it has also had support from the medical establishment.
