Cuproptosis is a newly identified form of cell death induced by excessive copper (Cu) accumulation within cells. Mechanistically, cuproptosis results from Cu-induced aggregation dihydrolipoamide S-acetyltransferase, correlated with the mitochondrial tricarboxylic acid cycle and loss iron–sulfur cluster proteins, ultimately resulting in proteotoxic stress triggering death. Recently, has garnered significant interest tumor research due to its potential as crucial therapeutic strategy against cancer. In this review, we summarized cellular molecular mechanisms relationship other types Additionally, reviewed current drugs or strategies available induce cells, including Cu ionophores, small compounds, nanomedicine.

Radiotherapy (RT) is a primary clinical approach for cancer treatment, but its efficacy often hindered by various challenges, especially radiation resistance, which greatly compromises the therapeutic effectiveness of RT. Mitochondria, central to cellular energy metabolism and regulation cell death, play critical role in mechanisms radioresistance. In this context, cuproptosis, novel copper-induced mitochondria-respiratory-dependent death pathway, offers promising avenue radiosensitization. study, an innovative theranostic nanoplatform was designed induce cuproptosis synergy with low-dose therapy (LDRT, i.e., 0.5–2 Gy) treatment situ hepatocellular carcinoma (HCC). This aims reverse hypoxic tumor microenvironment, promoting shift from glycolysis oxidative phosphorylation (OXPHOS), thereby enhancing sensitivity cuproptosis. Concurrently, Fenton-like reaction ensures sustained supply copper depletion glutathione (GSH), inducing disrupting mitochondrial function, interrupting supply. strategy effectively overcomes radioresistance enhances against tumors. conclusion, study elucidates intricate interactions among hypoxia reversal, metabolic reprogramming, radiosensitization, particularly context treating carcinoma, providing paradigm radiotherapy.

DEAD-box ATPase 10 (DDX10), a prominent RNA-binding protein in the DDX family, has critical function cancer progression. Nevertheless, its well-defined mechanisms oral squamous cell carcinoma (OSCC) are still not well understood. Here, we identify that DDX10 is substantially increased OSCC, which positively correlated with poor prognosis and malignant behavior. Mechanistically, found had physical interaction Rab27b by undergoing phase separation. Knockdown of inhibited Rab27b-mediated exosome secretion expression programmed death-ligand 1 (PD-L1) within contents. Furthermore, knocking down could restore infiltration T cells, hence inhibiting progression OSCC. These findings highlight oncogenic role promoting exosomal PD-L1 via separation been preliminarily validated exhaustion A potential strategy for improving OSCC immunotherapy may involve inhibition DDX10.

ABSTRACT An extracellular acidic environment and an intracellular mildly alkaline induced by carbonic anhydrase 9 (CA9) play a critical role in self‐renewal, invasion, migration, drug resistance of cancer stem cells (CSCs) within hypoxic solid tumors. Here, we report antitumor strategy leveraging hyperbaric oxygen therapy (HBO) to regulate tumor pH boost hydroxyethyl starch‐doxorubicin‐copper nanoparticles (HHD‐Cu NPs) against CSCs. HBO overcomes hypoxia, downregulates pH‐regulatory proteins such as CA9, leads accumulation metabolites. As result, promotes acidification both CSCs, triggering efficient doxorubicin release the potent copper‐mediated chemical dynamic effect subsequently administered dual‐acid‐responsive HHD‐Cu NPs. The combination with NPs not only eliminates but also inhibits altogether leading inhibition. This study explores new function clinical‐widely used establishes novel for treating CSCs abundant

Abstract Although self‐assembly has emerged as an effective tool for fabricating biomaterials, achieving precise control over the morphologies and functionalities of resultant assemblies remains ongoing challenge. Inspired by copper peptide naturally present in human plasma, this study, we designed a synthetic precursor, FcGH. FcGH can self‐assemble via two distinct pathways: spontaneous Cu 2+ ‐induced. These assembly pathways enabled formation with tunable adjusting amount added . We found that nanoparticles formed ‐induced exhibited significantly higher cellular uptake efficiency than wormlike fibers spontaneously. Moreover, process occurred spontaneously at 1 : molar ratio to FcGH, avoiding excessive use tedious preparation procedure. By co‐assembling 10‐hydroxycamptothecin (HCPT)‐conjugated supramolecular nanodrugs elicited multiple cell death modalities cancer cells elevated immunogenicity, enhancing therapeutic effect compared free HCPT. This study highlights efficient directing synergistic tumor therapy.
