| Chemotherapy is a treatment approach that uses drugs to target and kill rapidly dividing cells, primarily cancer cells. However, because many normal cells also divide quickly (such as those in the bone marrow, digestive tract, and hair follicles), chemotherapy can also affect these cells, leading to a range of side effects. Main Classes of Chemotherapy Agents and Examples Alkylating Agents: -work by adding alkyl groups to DNA, which interferes with the DNA’s structure and prevents replication. Examples: Cyclophosphamide, Ifosfamide, Melphalan, Chlorambucil, Busulfan. Anti-metabolites: -interfere with DNA and RNA synthesis by substituting for the normal building blocks of nucleic acids. Examples: Methotrexate, 5-Fluorouracil (5-FU), Cytarabine, Gemcitabine, 6-Mercaptopurine. Anti-microtubule Agents: -interfere with the structures that separate chromosomes during cell division (mitosis). Examples: Paclitaxel, Docetaxel, Vincristine, Vinblastine. Topoisomerase Inhibitors: -target the enzymes topoisomerase I and II, which control the changes in DNA structure required for replication. Examples: Etoposide (topoisomerase II inhibitor), Irinotecan (topoisomerase I inhibitor), Topotecan. Cytotoxic Antibiotics: -intercalate into DNA, inhibiting the replication of cancer cells. Examples: Doxorubicin, Daunorubicin, Bleomycin, Mitoxantrone. Platinum-Based Agents: -contain platinum and cause cross-linking of DNA, which interferes with DNA repair and replication. Examples: Cisplatin, Carboplatin, Oxaliplatin. Many chemotherapy agents exert their effects, at least in part, by inducing oxidative stress in cancer cells. They can increase ROS levels through several mechanisms: -Direct generation of free radicals. -Disruption of mitochondrial function, leading to increased production of ROS. -Interference with the cell’s antioxidant systems. -May want to avoid antioxidants 7 days bef ore and 7 days after chemo. Examples: NAC, Glutathione, Alpha Lipoic Acid, Vitamin E -anti-oxidants known to have pro-oxidant effects (like Quercetin, Curcumin, etc.) should not be taken 2-3 days before and after chemo -pro-oxidants known to bring good benefit to chemo can be continued during chemo. Examples are: Omega 3, Aremisia Annua, Silver NanoParticles. |

| Mitochondrial respiration plays a crucial role in the development and progression of cancer. Cancer cells often exhibit altered metabolic profiles, including changes in mitochondrial respiration, to support their rapid growth and proliferation. In cancer cells, mitochondrial respiration is often downregulated, and instead, they rely on glycolysis for energy production, even in the presence of oxygen. This phenomenon is known as the "Warburg effect." There are several key players involved in the regulation of mitochondrial respiration in cancer cells, including: Pyruvate dehydrogenase (PDH): a critical enzyme that converts pyruvate into acetyl-CoA, which is then fed into the citric acid cycle. Citrate synthase: an enzyme that catalyzes the first step of the citric acid cycle. Succinate dehydrogenase (SDH): an enzyme that participates in both the citric acid cycle and the electron transport chain. Cytochrome c oxidase (COX): the final enzyme in the electron transport chain, responsible for generating ATP. Alterations in the expression and activity of these enzymes can impact mitochondrial respiration in cancer cells. For example, increased expression of PDH and citrate synthase can enhance mitochondrial respiration, while decreased expression of SDH and COX can impair it. Additionally, various transcription factors and signaling pathways regulate mitochondrial respiration in cancer cells, including: HIF-1α (hypoxia-inducible factor 1 alpha): a transcription factor that promotes glycolysis and suppresses mitochondrial respiration in response to hypoxia. c-Myc: a transcription factor that regulates the expression of genes involved in mitochondrial respiration and biogenesis. PI3K/Akt/mTOR: a signaling pathway that promotes cell growth and proliferation, in part by regulating mitochondrial respiration. |
