Int J Chron Obstruct Pulmon Dis 2021; 16:3347-3362. [PMID: 34934311 PMCID: PMC8684379 DOI: 10.2147/copd.s340113] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 11/22/2021] [Indexed: 12/12/2022] Open
Abstract
Background Nuclear factor E2-related factor 2 (Nrf2) is involved in oxidative stress and lung inflammation and regulates the etiology of chronic obstructive pulmonary disease (COPD). Ferroptosis is characterized by the accumulation of lipid reactive oxygen species (ROS) via ferrous ion-dependent Fenton reactions and is involved in COPD. However, the role of Nrf2 in ferroptosis and its epigenetic regulation in the pathogenesis of COPD remain unclear. Methods Ferroptosis was detected by 4-HNE, MDA, C11BODIPY, DCFH-DA, Peals’ staining and CCK-8 assays. qPCR and Western blotting were performed to examine the Nrf2 levels in peripheral lung tissues, primary epithelial cells collected from patients with COPD and subjects with normal pulmonary function (never-smoker [control-NS]; smoker [control-S]), and cigarette smoke extract (CSE)-treated human bronchial epithelial (HBE) cells. ELISA was used to quantify IL-8 and IL-1β levels. Methylation of the Nrf2 promoter was analyzed by bisulfite sequencing and pyrosequencing. Results Ferroptosis was involved in COPD and glutathione peroxidase 4 (GPX4) expression was downregulated in the COPD group. Reactive oxygen species (ROS), lipid peroxides and MDA were increased, but GPX4 and SOD were exhausted in CSE-treated HBE cells. The production of IL-1β and IL-8 was promoted in HBE cells in response to CSE but could be reversed by the ferroptosis inhibitor fer-1. The Nrf2 level was significantly decreased in the COPD group compared with the control-S and control-NS groups. Increased Nrf2 expression enhanced GPX4 and SOD levels and inhibited ferroptosis and proinflammatory cytokines in the supernatant. Inhibition of GPX4 reversed the effect of Nrf2 overexpression and promoted ferroptosis. Two specific CpG sites within the Nrf2 promoter were hypermethylated in the COPD group. Similarly, CSE-treated HBE cells exhibited hypermethylation of the Nrf2 gene. Conclusion Nrf2 expression was downregulated in the lungs of COPD patients due to hypermethylation of the Nrf2 promoter, inhibiting Nrf2/GPX4 and ferroptosis, which is related to the initiation and progression of COPD. Targeting Nrf2/GPX4 may inhibit ferroptosis, which could provide strategies to delay or treat COPD.

Abstract
Lung cancer is one of the most common cancers in the world. Although medical treatment has made impressive progress in recent years, it is still one of the leading causes of cancer-related deaths in men and women. Ferroptosis is a type of non-apoptotic cell death modality, usually characterized by iron-dependent lipid peroxidation, rather than caspase-induced protein cleavage. Excessive or lack of ferroptosis is associated with a variety of diseases, including cancer and ischaemia-reperfusion injury. Recent preclinical evidence suggests that targeting ferroptotic pathway is a potential strategy for the treatment of lung cancer. In this review, we summarize the core mechanism and regulatory network of ferroptosis in lung cancer cells, and highlight ferroptosis induction-related tumor therapies. The reviewed information may provide new insights for targeted lung cancer therapy.

Abstract
Sorafenib is a tyrosine kinase inhibitor that shows anti-tumour effects against various cancers including gastric cancer (GC). However, the clinical application of sorafenib is often hampered by drug resistance. Sirtuins 6 (SIRT6) is a member of the Sirtuin family of NAD (+)-dependent enzymes that are critically involved in various biological activities. This study presents that SIRT6 silencing overcomes sorafenib resistance by promoting ferroptosis, which is a novel form of cell death. Mechanistically, SIRT6 inhibition led to the inactivation of the Keap1/Nrf2 signalling pathway and downregulation of GPX4. The overexpression of GPX4 or activation of Keap1/Nrf2 reverses the effects of the downregulation of SIRT6 on sorafenib-induced ferroptosis. Thus, targeting the SIRT6/Keap1/Nrf2/GPX4 signalling pathway may be a potential strategy for overcoming sorafenib resistance in GC.

Abstract
Ferroptosis, a cell death modality characterized by iron-dependent lipid peroxidation, is involved in the development of multiple pathological conditions, including ischemic tissue damage, infection, neurodegeneration, and cancer. The cellular machinery responsible for the execution of ferroptosis integrates multiple pro-survival or pro-death signals from subcellular organelles and then 'decides' whether to engage the lethal process or not. Here, we outline the evidence implicating different organelles (including mitochondria, lysosomes, endoplasmic reticulum, lipid droplets, peroxisomes, Golgi apparatus, and nucleus) in the ignition or avoidance of ferroptosis, while emphasizing their potential relevance for human disease and their targetability for pharmacological interventions.

Abstract
Doxorubicin (DOX) is extensively applied in cancer therapy due to its efficacy in suppressing cancer progression and inducing apoptosis. After its discovery, this chemotherapeutic agent has been frequently used for cancer therapy, leading to chemoresistance. Due to dose-dependent toxicity, high concentrations of DOX cannot be administered to cancer patients. Therefore, experiments have been directed towards revealing underlying mechanisms responsible for DOX resistance and ameliorating its adverse effects. Nuclear factor erythroid 2-related factor 2 (Nrf2) signaling is activated to increase levels of reactive oxygen species (ROS) in cells to protect them against oxidative stress. It has been reported that Nrf2 activation is associated with drug resistance. In cells exposed to DOX, stimulation of Nrf2 signaling protects cells against cell death. Various upstream mediators regulate Nrf2 in DOX resistance. Strategies, both pharmacological and genetic interventions, have been applied for reversing DOX resistance. However, Nrf2 induction is of importance for alleviating side effects of DOX. Pharmacological agents with naturally occurring compounds as the most common have been used for inducing Nrf2 signaling in DOX amelioration. Furthermore, signaling networks in which Nrf2 is a key player for protection against DOX adverse effects have been revealed and are discussed in the current review.

Abstract
Gefitinib resistance in triple negative breast cancer (TNBC) is a growing important concern. Glutathione peroxidase 4 (GPX4) is a main regulator of ferroptosis, which is pivotal for TNBC cell growth. We investigated GPX4-mediated ferroptosis in gefitinib sensitivity in TNBC. Gefitinib resistant TNBC cells MDA-MB-231/Gef and HS578T/Gef were constructed and treated with lentivirus sh-GPX4 and ferroptosis inhibitor ferrostatin-1. GPX4 expression, cell viability and apoptosis were detected. Malondialdehyde (MDA), glutathione (GSH), reactive oxygen species (ROS) levels were evaluated. The levels of ferroptosis-related proteins were detected. Subcutaneous tumor model was established in nude mice, and gefitinib was intraperitoneally injected to evaluate tumor growth, apoptosis, and Ki-67 expression. GPX4 was increased in gefitinib-resistant cells. After silencing GPX4, the inhibition rate of cell viability was increased, the limitation of colony formation ability was reduced, apoptosis rate was increased, and the sensitivity of cells to gefitinib was improved. After silencing GPX4, MDA and ROS production were increased, while GSH was decreased. Silencing GPX4 promoted ferroptosis. Inhibition of GPX4 promoted gefitinib sensitivity by promoting cell ferroptosis. In vivo experiments also revealed that inhibition of GPX4 enhanced the anticancer effect of gefitinib through promoting ferroptosis. Overall, inhibition of GPX4 stimulated ferroptosis and enhanced TNBC cell sensitivity to gefitinib.
