Abstract:Ferroptosis is a novel regulatory cell death, which is characterized by iron dependency and mainly caused by accumulation of intracellular lipid peroxides and reactive oxygen species. Ferroptosis plays an important role in the occurrence and development of a variety of malignant tumors, especially in anti-tumor treatment. As an emerging treatment method, the immunotherapy has been widely applied in the clinical practice, and the role of ferroptosis in tumor immunotherapy has been gradually explored.

“…Ferroptosis differs from other cell death modalities in many ways and the regulatory mechanisms are complex and diverse. Studies have shown that it is mainly related to cellular metabolic regulation, gene regulation, associated autophagy, and other compounds that have both inductive and inhibitory effects on ferroptosis (Xu et al, 2022). Among them, the cellular metabolic regulatory system is mainly involved in three classical mechanisms, namely, imbalance of iron metabolism, dysregulation of the amino acid antioxidant system, and lipid peroxidation pooling (Deng et al, 2023).…”

Osteoporosis, a chronic metabolic bone disease, has a serious impact on the quality of life of postmenopausal women and elderly men. Its prevalence is on the rise as the population ages worldwide. There are many drawbacks to the current clinical approaches to treatment, and traditional chinese medicine (TCM) has long had a unique advantage in the prevention and treatment of osteoporosis. As research in the field of ferroptosis continues to intensify, the study of TCM has become a hot area in the treatment of the disease through multimethod interventions for ferroptosis. Based on this, this study searched the Cochrane Library, PubMed, Embase, CBM, CNKI, WanFang Data, and VIP databases using osteoporosis, TCM, and ferroptosis as keywords. Up to April 2023, research literature on the relationship between TCM, osteoporosis, and ferroptosis was collected. The results found a strong relationship between the main regulatory mechanisms of ferroptosis and osteoporosis. TCM methods with good therapeutic effects on osteoporosis, such as Zanthoxylum bungeanum, Curcumae longae, Salvia miltiorrhiza, Astragalus membranaceus, Bushen Huanjing Recipe, and external treatment of TCM, can all achieve interventions on ferroptosis under different pathways. It provides a new theoretical basis and research direction for the future treatment of osteoporosis through multiple methods of TCM to intervene in ferroptosis.

“…Ferroptosis is a type of Fe 2+ -dependent cell death that damages polyunsaturated fatty acid-containing phospholipids in cellular membranes mediated by lipid peroxidation (LPO) [ 90 ]. In recent years, increasing numbers of natural and synthetic drugs related to ferroptosis have been identified [ 91 ].…”

The slightest change in the extra/intracellular concentration of metal ions results in amplified effects by signaling cascades that regulate both cell fate within the tumor microenvironment and immune status, which influences the network of antitumor immunity through various pathways. Based on the fact that metal ions influence the fate of cancer cells and participate in both innate and adaptive immunity, they are widely applied in antitumor therapy as immune modulators. Moreover, nanomedicine possesses the advantage of precise delivery and responsive release, which can perfectly remedy the drawbacks of metal ions, such as low target selectivity and systematic toxicity, thus providing an ideal platform for metal ion application in cancer treatment. Emerging evidence has shown that immunotherapy applied with nanometallic materials may significantly enhance therapeutic efficacy. Here, we focus on the physiopathology of metal ions in tumorigenesis and discuss several breakthroughs regarding the use of nanometallic materials in antitumor immunotherapeutics. These findings demonstrate the prominence of metal ion-based nanomedicine in cancer therapy and prophylaxis, providing many new ideas for basic immunity research and clinical application. Consequently, we provide innovative insights into the comprehensive understanding of the application of metal ions combined with nanomedicine in cancer immunotherapy in the past few years.

“…An innovative ferroptosis mutagen is the natural substance β-elemene, which is effective against human colorectal cancer (CRC) cells with KRAS mutation and inhibits tumor growth by inducing ferroptosis. Combining β-elemene with cetuximab could potentially provide a therapeutic alternative for CRC patients with RAS mutation [ 24 ]. Fig.…”
Section: Signaling Mechanisms Linked To Cancermentioning
Iron-dependent lipid peroxidation causes ferroptosis, a form of regulated cell death. Crucial steps in the formation of ferroptosis include the accumulation of ferrous ions (Fe2+) and lipid peroxidation, of which are controlled by glutathione peroxidase 4 (GPX4). Its crucial role in stopping the spread of cancer has been shown by numerous studies undertaken in the last ten years. Epithelial–mesenchymal transition (EMT) is the process by which epithelial cells acquire mesenchymal characteristics. EMT is connected to carcinogenesis, invasiveness, metastasis, and therapeutic resistance in cancer. It is controlled by a range of internal and external signals and changes the phenotype from epithelial to mesenchymal like. Studies have shown that mesenchymal cancer cells tend to be more ferroptotic than their epithelial counterparts. Drug-resistant cancer cells are more easily killed by inducers of ferroptosis when they undergo EMT. Therefore, understanding the interaction between ferroptosis and EMT will help identify novel cancer treatment targets. In-depth discussion is given to the regulation of ferroptosis, the potential application of EMT in the treatment of cancer, and the relationships between ferroptosis, EMT, and signaling pathways associated with tumors. Invasion, metastasis, and inflammation in cancer all include ferroptosis and EMT. The goal of this review is to provide suggestions for future research and practical guidance for applying ferroptosis and EMT in clinical practice.
