Using untargeted proteomic profiling, we identified SUCLG2 as a potential contributor of platinum resistance in LUAD. Further knockout of SUCLG2 significantly enhanced cellular sensitivity to platinum-based drugs. Mechanistically, using targeted metabolomics, we found that SUCLG2 conferred platinum resistance by promoting glutamine metabolism and facilitating the succinylation of glutaminase (GAC). This post‑translational modification enhanced GAC activity, thereby reducing ROS generation and suppressing apoptosis in LUAD cells. SUCLG2 was found to be highly expressed in both LUAD tissues and platinum-resistant cell lines. Consistent with cellular findings, animal experiments confirmed that elevated SUCLG2 expression critically contributes to platinum resistance in vivo.

This study aimed to identify CAF-enriched genes with translational relevance and to determine whether GLG1 mediates tumor–stromal crosstalk in bladder cancer. Single-cell RNA sequencing from bladder cancer tissues was integrated with Mendelian randomization, Bayesian colocalization, correlation analyses, immunostaining of clinical specimens, CAF-conditioned medium assays, GLG1 knockdown/overexpression, TGF-β1/Smad2/3 assessment, and xenograft modeling. Single-cell profiling of nine bladder cancer samples retained 60,561 cells and identified fibroblast-enriched transcriptional programs. Among 960 fibroblast-enriched genes, Mendelian randomization identified 22 genes whose genetically predicted expression was associated with bladder cancer risk, and colocalization prioritized GLG1, HES4, and HSP90B1. GLG1 was selected for validation because it showed fibroblast-enriched expression, genetic support for bladder cancer association, and shared cis-eQTL/GWAS signals. GLG1 expression was higher in tumor tissues than in adjacent normal tissues, consistent with a stromal localization pattern, and GLG1 positivity was associated with tumor invasiveness. Tumor-derived TGF-β1/Smad2/3 signaling contributed to GLG1 upregulation in fibroblasts. CAF-conditioned medium enhanced EJ-1 cell viability, migration, and Matrigel invasion; these effects were weakened by GLG1 silencing and strengthened by GLG1 overexpression in CAFs. In xenografts, CAFs-shGLG1 reduced tumor growth and Ki-67 positivity and increased TUNEL-positive tumor cells relative to CAFs-shNC, whereas CAFs-OE-GLG1 showed the opposite Ki-67 and TUNEL staining pattern. CAF-associated GLG1 promotes bladder cancer cell viability, migration, Matrigel invasion, and xenograft growth while limiting tumor-cell apoptosis, likely by reinforcing tumor–stromal crosstalk. These findings support GLG1 as a stromal factor involved in bladder cancer progression and provide a basis for further evaluation of its biomarker potential and therapeutic relevance.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"31 10","pages":""},"PeriodicalIF":9.0,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10495-026-02439-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protective autophagy supports resistance through metabolic adaptation, organelle quality control, immune evasion, and maintenance of cancer stemness, whereas excessive or dysregulated autophagy may trigger lethal self-digestion. Emerging studies show that small molecules can reprogram autophagy from a survival pathway into a cytotoxic process by targeting AMPK/mTOR/ULK1 signaling, stress-response pathways, lysosomal function, and selective autophagy networks such as mitophagy and ferritinophagy. Importantly, ADCD can bypass apoptosis resistance, eradicate drug-tolerant persister cells, and enhance therapeutic efficacy in refractory tumors.

The GOLPH3-CXCR4 interaction and GOLPH3-sialyltransferase associations were bioinformatically predicted (BIOGRAD) and validated experimentally via co-immunoprecipitation (Co-IP). CXCR4 sialylation was assessed by immunoprecipitation (IP) and lectin blotting (LB). Immunohistochemical (IHC) assessment of protein expression levels of Ki-67, GOLPH3, and CD206 in tissues. Functional assays, including colony formation, flow cytometry, scratch, and Transwell assays, evaluated proliferation, apoptosis, migration, and invasion in CRC. A co-culture system, flow cytometry, and Enzyme-Linked Immunosorbent Assay (ELISA) were conducted to assess macrophage M2 polarization, and a xenograft tumor model was constructed for in vivo validation. GOLPH3 promotes the interaction between CXCR4 and its ligand CXCL12 by inducing sialylation at the 180th amino acid residue of CXCR4. This regulatory mechanism plays an important role in modulating macrophage function, which manifests as facilitating cell proliferation, migration and invasion, suppressing cellular apoptosis, and promoting M2-type macrophage polarization. Furthermore, N180 mutation assays offer direct experimental evidence to validate the causal relationship within this regulatory network.

This risk is especially concerning for low- and middle-income countries (LMICs), where both PM<sub>2.5</sub> exposure and cancer burden are disproportionately high; however, mechanistic studies from these regions remain limited.

Anwulignan demonstrated potent cytotoxic activity against MM cells and exhibited strong synergy with proteasome inhibitors both in vitro and in vivo. In mouse MM models, anwulignan significantly suppressed tumor growth while maintaining favorable tolerability and safety profiles. Mechanistically, nucleophosmin 1 (NPM1) has been identified as a direct molecular target of anwulignan. Elevated NPM1 expression correlates with poor clinical outcomes in MM, and its inhibition by anwulignan induces cell cycle arrest and apoptosis. In addition to its tumor-intrinsic cytotoxic effects, anwulignan activated the caspase-1–dependent gasdermin D (GSDMD) pyroptosis pathway, thereby inducing immunogenic cell death. Genetic silencing of GSDMD markedly impaired anwulignan-mediated tumor suppression in vitro and in vivo, highlighting pyroptosis as a critical effector mechanism. In immunocompetent syngeneic MM models, anwulignan treatment increased bone marrow and splenic T-cell proportions and achieved superior tumor control compared with GSDMD-deficient tumors.

In immunocompetent mouse models, RNF166 overexpression accelerated tumor growth and suppressed CD8 + T-cell infiltration and cytotoxic function, while these effects were dependent on PD-L1 signaling and were attenuated in immunodeficient settings.

Cuproptosis is a recently identified form of regulated cell death in which copper binds to lipoylated mitochondrial proteins, promotes their aggregation, destabilises iron–sulfur cluster proteins, and induces mitochondrial proteotoxic stress. Copper therefore has context-dependent roles in cancer. Physiological copper supports tumour metabolism, angiogenesis, extracellular-matrix remodelling, and selected oncogenic signalling pathways, whereas therapeutic copper depletion can inhibit copper-dependent tumour processes. Conversely, copper ionophores and related approaches may increase intracellular copper sufficiently to induce cuproptosis in metabolically susceptible cancer cells. This review describes systemic and intracellular copper homeostasis, including intestinal absorption, intracellular trafficking, mitochondrial copper distribution, storage, and export. Particular attention is given to CTR1/SLC31A1, the functionally distinct copper-transporting ATPases ATP7A and ATP7B, metallothioneins, copper chaperones, and cytochrome c oxidase assembly factors. We also examine how cancer cells reprogramme copper handling to support proliferation, angiogenesis, metastasis, and immune evasion. Finally, we discuss the molecular basis of cuproptosis, including the roles of FDX1, FDXR, LIAS, DLAT, mitochondrial respiration, protein lipoylation, and iron–sulfur cluster destabilisation. Current evidence indicates that cuproptosis susceptibility varies among tumour types and depends on copper handling, mitochondrial metabolic state, and the integrity of the protein-lipoylation machinery. Defining these determinants will be necessary for the development of tumour-selective copper-targeted therapies.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"31 9","pages":""},"PeriodicalIF":9.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13541888/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148886313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
