Over the past decade, extensive research has been dedicated to understanding oxidative cell death, specifically transition from oxytosis ferroptosis. Oxytosis was initially characterized in 1989 as a calcium-dependent form of nerve death induced by glutamate. It associated with intracellular glutathione depletion and inhibition cystine uptake through system xc-, cystine-glutamate antiporter. In 2012, term "ferroptosis" coined during compound screening that aimed selectively induce RAS-mutated cancer cells. This identified erastin RSL3 inhibitors xc- peroxidase 4 (GPX4), respectively, triggering death. Subsequently, gradually fell out frequent usage, being replaced editorial provides narrative review significant findings, experimental models, molecular players involved ferroptosis, shedding light on its intricate mechanisms. Moreover, it discusses implications these findings various pathological conditions, including neurodegenerative disorders, cancer, ischemia-reperfusion disease. By summarizing decade-long progress made this field, present Forum serves valuable resource for researchers aiming unravel complex mechanisms underlying explore potential therapeutic interventions.

Background The interaction between pyroptosis—a form of programmed cell death—and tumor immunity represents a burgeoning field interest. Pyroptosis exhibits dual role in cancer: it can both promote development and counteract by activating immune responses that inhibit evasion encourage death. Current immunotherapy strategies, notably CAR-T therapy checkpoint inhibitors (ICIs), alongside the potential certain traditional Chinese medicinal compounds, highlight intricate relationship pyroptosis cancer immunity. As research delves deeper into mechanisms within therapy, its application enhancing emerges as novel avenue. Purpose This review aims to elucidate underlying pyroptosis, impact on biology, advancements research.

Protein lactylation is a new form of post-translational modification that has recently been proposed. Lactoyl groups, derived mainly from the glycolytic product lactate, have linked to protein in brain tissue, which shown correlate with increased neuronal excitability. Ischemic stroke may promote glycolysis, leading lactate accumulation tissue. This heighten excitability by upregulating levels, potentially triggering post-stroke epilepsy. Although current clinical treatments for seizures advanced significantly, approximately 30% patients epilepsy remain unresponsive medication, and prevalence continues rise. study explores mechanisms epilepsy-associated death mediated metabolism lactylation. also examines potential histone deacetylase inhibitors alleviate modifying thereby offering fresh perspectives future research into pathogenesis treatment

In the evolving landscape of cancer treatment, strategic manipulation regulated cell death (RCD) pathways has emerged as a crucial component effective anti-tumor immunity. Evidence suggests that tumor cells undergoing RCD can modify immunogenicity microenvironment (TME), potentially enhancing its ability to suppress progression and metastasis. this review, we first explore mechanisms apoptosis, necroptosis, pyroptosis, ferroptosis, cuproptosis, along with crosstalk between these modalities. We then discuss how processes activate antigen-presenting cells, facilitate cross-priming CD8+ T trigger immune responses, highlighting complex effects novel forms on TME biology. Furthermore, summarize potential drugs nanoparticles induce or inhibit emerging their therapeutic roles in treatment. Finally, put forward existing challenges future prospects for targeting anti-cancer Overall, review enhances our understanding molecular biological impacts RCD-based therapies, providing new perspectives strategies

Abstract Copper, an essential micronutrient, plays significant roles in numerous biological functions. Recent studies have identified imbalances copper homeostasis across various cancers, along with the emergence of cuproptosis, a novel copper-dependent form cell death that is crucial for tumor suppression and therapeutic resistance. As result, manipulating levels has garnered increasing interest as innovative approach to cancer therapy. In this review, we first delineate at both cellular systemic levels, clarifying copper’s protumorigenic antitumorigenic functions cancer. We then outline key milestones molecular mechanisms including mitochondria-dependent independent pathways. Next, explore cuproptosis biology, well interactions mediated by between cells immune system. also summarize emerging opportunities targeting discuss clinical associations cuproptosis-related genes. Finally, examine potential biomarkers put forward existing challenges future prospects leveraging Overall, review enhances our understanding landscape cancer, highlighting copper- or cuproptosis-based therapies treatment.

Cell death is a complex process required to maintain homeostasis and occurs when cells are damage or reach end of life. As research progresses, it apparent that necrosis apoptosis do not fully explain the whole phenomenon cell death. Therefore, new modalities such as autophagic death, ferroptosis have been proposed. In recent years, ferroptosis, type non-apoptotic characterized by iron-dependent lipid peroxidation reactive oxygen species (ROS) accumulation, has receiving increasing attention. Ferroptosis can be involved in pathological processes many disorders, ischemia-reperfusion injury, nervous system diseases, blood diseases. However, specific mechanisms which participates occurrence development leukemia still need more deeply studied. this review, we present progress on mechanism its role leukemia, provide theoretical basis strategies for diagnosis treatment clinical hematological
