| 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. |

| (Also known as Hsp32 and HMOX1) HO-1 is the common abbreviation for the protein (heme oxygenase‑1) produced by the HMOX1 gene. HO-1 is an enzyme that plays a crucial role in various cellular processes, including the breakdown of heme, a toxic molecule. Research has shown that HO-1 is involved in the development and progression of cancer. -widely regarded as having antioxidant and cytoprotective effects -The overall activity of HO‑1 helps to reduce the pro‐oxidant load (by degrading free heme, a pro‑oxidant) and to generate molecules (like bilirubin) that can protect cells from oxidative damage Studies have found that HO-1 is overexpressed in various types of cancer, including lung, breast, colon, and prostate cancer. The overexpression of HO-1 in cancer cells can contribute to their survival and proliferation by: Reducing oxidative stress and inflammation Promoting angiogenesis (the formation of new blood vessels) Inhibiting apoptosis (programmed cell death) Enhancing cell migration and invasion When HO-1 is at a normal level, it mainly exerts an antioxidant effect, and when it is excessively elevated, it causes an accumulation of iron ions. A proper cellular level of HMOX1 plays an antioxidative function to protect cells from ROS toxicity. However, its overexpression has pro-oxidant effects to induce ferroptosis of cells, which is dependent on intracellular iron accumulation and increased ROS content upon excessive activation of HMOX1. -Curcumin Activates the Nrf2 pathway leading to HO‑1 induction; known for its anti‑inflammatory and antioxidant effects. -Resveratrol Induces HO‑1 via activation of SIRT1/Nrf2 signaling; exhibits antioxidant and cardioprotective properties. -Quercetin Activates Nrf2 and related antioxidant pathways; contributes to anti‑oxidative and anti‑inflammatory responses. -EGCG Promotes HO‑1 expression through activation of the Nrf2/ARE pathway; also exhibits anti‑inflammatory and anticancer properties. -Sulforaphane One of the most potent natural HO‑1 inducers; triggers Nrf2 nuclear translocation and upregulates a battery of phase II detoxifying enzymes. -Luteolin Induces HO‑1 via Nrf2 activation; may also exert anti‑inflammatory and neuroprotective effects in various cell models. -Apigenin Has been reported to induce HO‑1 expression partly via the MAPK and Nrf2 pathways; also known for anti‑inflammatory and anticancer activities. |
