Abstract Many types of human cells self-destruct to maintain biological homeostasis and defend the body against pathogenic substances. This process, called regulated cell death (RCD), is important for various activities, including clearance aberrant cells. Thus, RCD pathways represented by apoptosis have increased in importance as a target development cancer medications recent years. However, because tumor show avoidance apoptosis, which causes treatment resistance recurrence, numerous studies been devoted alternative mortality processes, namely necroptosis, pyroptosis, ferroptosis, cuproptosis; these modalities extensively studied shown be crucial therapy effectiveness. Furthermore, evidence suggests that undergoing may alter immunogenicity microenvironment (TME) some extent, rendering it more suitable inhibiting progression metastasis. In addition, other components TME undergo abovementioned forms induce immune attacks on cells, resulting enhanced antitumor responses.

As a newly identified type of programmed cell death, cuproptosis may have an impact on cancer development, including clear renal carcinoma (ccRCC). Herein, we first noticed that the expression levels regulators exhibited tight correlation with clinicopathological characteristics ccRCC. The cuproptosis-sensitive sub-type (CSS), classified via consensus clustering analysis, harbored higher overall survival rate compared to cuproptosis-resistant (CRS), which resulted from differential infiltration immune cells. FDX1, master regulator, was experimentally determined as tumor suppressor in ccRCC cells by suppressing growth and invasion ACHN OSRC-2 cuproptosis-dependent -independent manner. results IHC staining also demonstrated FDX1 negatively correlated initiation progression. Furthermore, miR-21-5p/FDX1 axis verified miR-21-5p directly binds 3′-UTR mediate its degradation. Consequently, inhibitor suppressed cells, could be compensated knockdown, reinforcing functional linkage between Finally, evaluated microenvironment under noted this strongly associated such CD4+ T Treg macrophages, suggesting signaling alter microenvironmental components drive Overall, study constructed analyzed potential microenvironment, providing valuable insights improve current management.

Tuberculosis (TB) caused by Mycobacterium tuberculosis (M.tb) remains a global health crisis, with over 10 million people affected annually. Despite advancements in treatment, M.tb has developed mechanisms to evade host immune responses, complicating efforts eradicate the disease. Two emerging cell death pathways, ferroptosis and cuproptosis, have been linked TB pathogenesis. Ferroptosis, an iron-dependent form of death, is driven lipid peroxidation reactive oxygen species (ROS) accumulation. This process can limit replication depleting intracellular iron inducing macrophage necrosis. However, excessive may lead tissue damage aid bacterial dissemination. Cuproptosis, triggered copper accumulation, disrupts mitochondrial metabolism, leading protein aggregation death. exploits both metabolism survive within macrophages, manipulating these processes resist oxidative stress responses. review examines roles cuproptosis TB, discussing how manipulates pathways for survival. While therapeutic strategies targeting processes, such as inducers (Erastin, RSL3) inhibitors (Ferrostatin-1) ionophores (Disulfiram, Elesclomol) chelators, show promise, limited understanding potential off-target effects significant challenge. Further exploration provide insights into development targeted therapies aimed at controlling infection while minimizing damage. By elucidating complex interactions between ferroptosis, future could better address resistance improve clinical outcomes.
