Suzuki-Karasaki M, Ochiai Y, Innami S, Okajima H, Suzuki-Karasaki M, Nakayama H, Suzuki-Karasaki Y. Ozone mediates the anticancer effect of air plasma by triggering oxidative cell death caused by H 2O 2 and iron. Eur J Cell Biol 2023; 102:151346. [PMID: 37572557 DOI: 10.1016/j.ejcb.2023.151346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 07/01/2023] [Accepted: 08/02/2023] [Indexed: 08/14/2023] Open
Abstract
Cold atmospheric plasmas and plasma-treated solutions (PTSs) have emerged as promising approaches in cancer treatment because of their tumor-selective actions. While oxidative stress is critical for their effects, the precise mechanisms, including chemical mediators, remain obscure. Previously, we reported that air plasma-activated medium (APAM) exhibited tumor-selective anticancer activity. The fragmentation of mitochondria and their asymmetrical assembly around the peripheral regions of the damaged nucleus, namely, monopolar perinuclear mitochondrial clustering (MPMC), proceed to the effect. Subsequently, we found that APAM had a substantial amount of O3 in addition to hydrogen peroxide (H2O2), nitrile (NO2-), and nitrate (NO3-). In the present study, we investigated the possible role of O3 in the anticancer effect. For this purpose, we created a nitrogen oxide-free ozonated medium ODM. ODM exhibited potent cytotoxicity against various cancer but not nonmalignant cells. ODM also increased MPMC, hydroxyl radicals, lipid peroxides, and their shifts to perinuclear sites in cancer cells. Catalase and iron chelation prevented these events and cytotoxicity. ODM also decreases the intracellular labile irons while increasing those within mitochondria. ODM had substantial H2O2, but this oxidant failed to cause MPMC and cytotoxicity. These results show that ODM can mimic the effects of APAM, including MPMC and tumor-selective anticancer effects. The findings suggest that O3 is critical in mediating the anticancer effects of APAM by triggering oxidative cell death caused by H2O2 and iron.

Abstract
High-grade gliomas (grades III and IV) are highly malignant and aggressive brain tumors that present significant treatment challenges. Despite advances in surgery, chemotherapy, and radiation therapy, the prognosis for patients with glioma remains poor, with a median overall survival (mOS) range of 9-12 months. Therefore, exploring new and effective therapeutic strategies to improve glioma prognosis is of utmost importance and ozone therapy is a viable option. Ozone therapy has been used in various cancers, such as colon, breast, and lung, yielding significant results in preclinical studies and clinical trials. Only a few studies have been conducted on gliomas. Furthermore, since the metabolism of brain cells involves aerobic glycolysis, ozone therapy may improve the oxygen condition and enhance glioma radiation treatment. However, understanding the correct ozone dosage and optimal time of administration remains challenging. Herein, we hypothesize that ozone therapy should be more effective in gliomas compared with other tumors. This study provides an overview of the use of ozone therapy in high-grade glioma, including mechanisms of action, preclinical data, and clinical evidence.

Abstract
Cancer is the second leading cause of death worldwide, after cardiovascular diseases. Increasing patients’ awareness and providing easier access to public information result in greater interest in alternative anticancer or unproven supportive therapies. Fear of cancer and limited trust in the treating physician are also important reasons leading patients to seek these methods. Trust and good communication are essential to achieving truthful collaboration between physicians and patients. Given the popularity of CAM, better knowledge about these alternative practices may help oncologists discuss this issue with their patients. This article objectively reviews the most common unconventional therapies used by cancer patients.

Abstract
In the last sixty years, publications in reputed journals have shown the preclinical positive effect of ozone gas in cancer cells. However, the translation of these results into clinical practice is far away from success. A comprehensive approach is necessary for this, and oncologists and researchers need guidance from medical specialists with in-depth knowledge of ozone in medicine. In this article, we review the evidence around this question and suggest different potential research lines to those interested in this exciting field.

Abstract
Background Oxidative stress is an important factor in the modulation of both tumorigenesis and anticancer responses. Ozone (O3) is a strong oxidant that causes redox reactions and exerts anticancer effects in various types of cancer cells. However, the pathways involved in O3-induced cell death are not well understood. Methods In vitro human hepatocellular carcinoma (HCC) BEL7402 cells were treated with various O3 concentrations to evaluate O3 cytotoxicity by Cell Counting Kit-8 (CCK-8) assay and flow cytometry. The regulatory mechanisms were analyzed by western blot analysis. In vivo, an HCC model was established to evaluate the inhibition of HCC with O3 treatment. Results In vitro cells treated with O3 exhibited a round and small morphology with nuclear shrinkage and fragmentation. The CCK-8 assay confirmed the potent cytotoxic activity of O3 against BEL7402 cells (IC50 value of 5 µg/mL). Acridine orange/ethidium bromide (AO/EB) staining revealed apoptosis of BEL7402 cells after O3 treatment. Flow cytometry analysis showed that S phase cell cycle arrest and apoptosis increased with O3 exposure. In addition, O3 exposure reduced the mitochondrial membrane potential (ΔΨm) and induced reactive oxygen species (ROS) accumulation. Western blot analysis showed that O3 exposure reduced B-cell lymphoma 2 (BCL-2) expression and increased cleaved poly ADP-ribose polymerase (PARP), cytochrome C (Cyt-C), caspase-3, caspase-9, and p-JNK expression. In vivo, treatment with intratumor injection O3 (20 µg/mL) inhibited HCC growth. Conclusions Overall, our findings showed that O3 induces BEL7402 cell apoptosis via the intrinsic mitochondria-dependent pathway. Therefore, O3 has therapeutic potential for HCC.

Ozone Therapy as Adjuvant for Cancer Treatment: Is Further Research Warranted? EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:7931849. [PMID: 30271455 PMCID: PMC6151231 DOI: 10.1155/2018/7931849] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Accepted: 07/09/2018] [Indexed: 12/20/2022]
Abstract
Introduction This article provides an overview of the potential use of ozone as an adjuvant during cancer treatment. Methods We summarize the findings of the most relevant publications focused on this goal, and we include our related clinical experience. Results Over several decades, prestigious journals have published in vitro studies on the capacity of ozone to induce direct damage on tumor cells and, as well, to enhance the effects of radiotherapy and chemotherapy. Indirect effects have been demonstrated in animal models: immune modulation by ozone alone and sensitizing effect of radiotherapy by concurrent ozone administration. The effects of ozone in modifying hemoglobin dissociation curve, 2,3-diphosphoglycerate levels, locoregional blood flow, and tumor hypoxia provide additional support for potential beneficial effects during cancer treatment. Unfortunately, only a few clinical studies are available. Finally, we describe some works and our experience supporting the potential role of local ozone therapy in treating delayed healing after tumor resection, to avoid delays in commencing radiotherapy and chemotherapy. Conclusions In vitro and animal studies, as well as isolated clinical reports, suggest the potential role of ozone as an adjuvant during radiotherapy and/or chemotherapy. However, further research, such as randomized clinical trials, is required to demonstrate its potential usefulness as an adjuvant therapeutic tool.
