Building on evidence from lung and other solid tumors, we summarize how aberrant SOX9 expression, shaped by epigenetic modification, post-translational regulation, and non-coding RNAs, drives proliferation, survival, invasion, and therapy resistance. In lung cancer, SOX9 appears to orchestrate a stem-like, plastic cell state, promoting epithelial-mesenchymal transition (EMT), metastatic dissemination, and remodeling of the tumor microenvironment (TME). These context-dependent functions position SOX9 both as an oncogenic driver and, in selected settings, as a modulator of treatment response. This review integrates current mechanistic and translational data to frame SOX9 as a clinically actionable node within key signaling circuits relevant to non-small cell and small cell lung cancer. We highlight emerging strategies that directly or indirectly target SOX9, including interference with upstream pathways, epigenetic reprogramming, and RNA-based approaches designed to modulate SOX9 expression or activity. Finally, we propose SOX9 as a dual biomarker and therapeutic handle to guide rational combination therapies aimed at overcoming drug resistance and improving patient stratification. By connecting molecular insight with unmet clinical needs, this article outlines a conceptual roadmap for SOX9-centered therapeutic approaches in lung cancer. A key novelty of this review is the integration of SOX9-centered molecular mechanisms with therapeutic resistance, biomarker potential, and emerging indirect targeting strategies in lung cancer, thereby providing a translational framework for future SOX9-guided interventions.</p>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":"40 5","pages":"e70862"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147838354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spindle and kinetochore-associated complex subunit 3 (SKA3), a microtubule-binding subcomplex of the outer kinetochore, participates in cancer progression. However, its role in the progression of LSCC remains unclear. This study aimed to investigate the regulatory effects of SKA3 on LSCC progression and its underlying mechanism. In this study, the expression levels of SKA3 and aldo-keto reductase family 1 member C1 (AKR1C1) mRNA were assessed by quantitative real-time PCR. Protein expression was evaluated using western blotting. Cell proliferation was analyzed using the cell counting kit-8 assay, while apoptosis was assessed by flow cytometry. Cell migration and invasion were measured via Transwell assays. The levels of Fe2+ and glutathione were analyzed with colorimetric assays, while reactive oxygen species (ROS) levels were determined by flow cytometry. Chromatin immunoprecipitation and dual-luciferase reporter assays were employed to explore the interaction between SOX9 and SKA3. The impact of SKA3 silencing and AKR1C1 overexpression on tumor formation was investigated using a xenograft mouse model. The results showed that SKA3 expression was elevated in LSCC tissues and cells when compared with corresponding normal tissues and human nasopharyngeal epithelial cells. Silencing SKA3 suppressed LSCC cell proliferation, migration, and invasion, while promoting apoptosis and ferroptosis. SKA3 upregulated AKR1C1, a key ferroptosis-related gene, in TU177 and AMC-HN-8 cells. Overexpression of AKR1C1 mitigated the effects of SKA3 silencing on the malignant phenotypes of these cells. SOX9 was identified as a transcriptional activator of SKA3 in TU177 and AMC-HN-8 cells, and AKR1C1 overexpression reversed the inhibitory effect of SKA3 silencing on tumor growth in vivo. Thus, SKA3 played a pivotal role in the progression of LSCC through the SOX9/SKA3/AKR1C1 axis, suggesting that targeting SKA3 might have significant clinical implications for the treatment of LSCC.</p>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":"40 5","pages":"e70874"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147815538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to traditional, labor-intensive diagnostic process, deep learning-based automatic detection algorithms can reduce diagnosis time, lower costs and improve accuracy. In this research, a kidney cancer detection model using deep learning is introduced to speed up the diagnosis process with high efficiency. At first, the input images are taken from benchmark sites.

The development of a tumor is identified in the early stages by this accurate segmentation procedure.

The article first dissects the interplay between TAMs and CD8⁺ T cells and their pivotal role in tumor immune escape. It then comprehensively reviews how TCM formulations and active components, through their characteristic multi-target actions, coordinately reverse TAM polarization and T cell exhaustion by modulating key signaling pathways (e.g., STAT, PI3K/Akt), reprogramming cellular metabolism (e.g., glycolysis, oxidative phosphorylation), and reshaping cytokine networks. Particular emphasis is placed on metabolic reprogramming as an upstream \"bridging\" mechanism that concurrently regulates both processes. Finally, the review explores the synergistic potential of combining TCM with immune checkpoint inhibitors and analyzes current challenges, including compositional complexity, insufficient mechanistic depth, and a paucity of high-quality clinical evidence.
