Although it is increasingly recognized as a central determinant of immune defense, therapeutic response, and disease progression, PANoptosis remains largely undetectable using current molecular imaging and detection strategies. Most existing molecular probes are designed to interrogate individual cell death pathways, typically apoptosis, thereby reducing a multidimensional execution network to a single biochemical readout. Here, we critically examine why conventional cell death probes fail to resolve PANoptosis and systematically categorize current sensing strategies according to their apoptotic, pyroptotic, and necroptotic targets. We further highlight emerging multiplexed, logic-gated, and nanoplatform-based sensing architectures that partially address these limitations but remain mechanistically incomplete. Building on current insights into PANoptosome biology, we propose a set of design principles for next-generation PANoptosis probes that emphasize multi-axis molecular integration, temporal resolution, and conditional activation logic. By reframing PANoptosis as a measurable biological state rather than a conceptual abstraction, this review provides a roadmap for developing molecular probes capable of decoding inflammatory cell death in complex diseases.

However, the functional role and molecular mechanisms of MAGED4 in hepatocellular carcinoma (HCC) remain largely unknown. In this study, we observed that MAGED4 expression levels were significantly higher in HCC tissues than in non-cancerous tissues and elevated expression was associated with poor patient outcomes. Functional assays demonstrated that MAGED4 promoted proliferation and migration of HCC. We found that MAGED4 can activate the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway. Mass spectrometry and co-immunoprecipitation assays revealed an interaction between MAGED4 and tripartite motif-containing 21 (TRIM21). Confocal microscopy experiments confirmed the colocalization of MAGED4 with TRIM21. Mechanistically, MAGED4 can regulate the stability of TRIM21 by preventing its ubiquitination and degradation. Furthermore, MAGED4 contributes to the downregulation of suppressor of cytokine signaling 3 (SOCS3) via TRIM21, and this effect can be partially reversed by si-TRIM21 in MAGED4-overexpressing cells. These findings indicate that MAGED4 promotes HCC progression through the activation of the JAK2/STAT3 pathway by stabilizing TRIM21, suggesting that targeting MAGED4 may provide new insights into HCC treatment strategies.</p>","PeriodicalId":9686,"journal":{"name":"Cell Cycle","volume":"25 1","pages":"1-15"},"PeriodicalIF":3.9,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13271336/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148216627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
