Central to this field is the dynamic, bidirectional regulatory network between the nervous system and tumor cells that orchestrates malignant progression. This review focuses on tumors arising outside the central nervous system and their bidirectional interactions with peripheral nerves, summarizing the current evidence on the molecular mechanisms underlying these reciprocal interactions. We first examine how neural components modulate tumorigenesis through the release of neuroactive molecules and proteins that activate oncogenic signaling pathways. In particular, neurons and Schwann cells can transmit protumorigenic signals via paracrine signaling, exosome-mediated communication, and the formation of functional neuroneoplastic synapses. Conversely, tumors can actively \"hijack\" and remodel their neural architecture to promote axonogenesis and neural infiltration while contributing to complications such as cancer pain and paraneoplastic neurological syndromes. We further highlight the pivotal role of neural signaling in reshaping the tumor microenvironment across three interconnected dimensions: the spatial dimension (neural niches), the signaling dimension (bidirectional communication mediated by neuroactive molecules), and the functional dimension (immunometabolic reprogramming). Together, these processes contribute to tumor progression and immune evasion. Building on these insights, therapeutic strategies targeting the neural-tumor interface have shown promising clinical potential. Further characterization of these regulatory networks may identify context-specific drivers of tumorigenesis and progression and inform the development of novel therapeutics targeting neural pathways.</p>","PeriodicalId":54225,"journal":{"name":"Biomarker Research","volume":"14 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13602479/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149031524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While targeting the canonical VHL-hypoxia-inducible factor (HIF) axis (e.g. belzutifan) has improved advanced clear cell renal cell carcinoma (ccRCC) management, intrinsic non-responsiveness and acquired resistance to HIF-2α inhibitors present major clinical limitations. Expanding beyond the HIF-centric paradigm reveals a broader network of non-canonical VHL targets, offering new opportunities for therapeutic development across ccRCC and pan-cancer contexts. This review provides an evidence-graded synthesis of novel VHL targets spanning epigenetic regulation (e.g. ZHX2, SETDB1, METTL3/METTL14), metabolic reprogramming (e.g. NDRG3, TFAM), extracellular matrix architecture (e.g. fibronectin, COL4A2), and immune modulation (e.g. TBK1). Supporting evidence across these targets ranges from direct biochemical ubiquitination to indirect downstream observations, derived predominantly from preclinical cell-line and xenograft models. Disruption of VHL and these non-HIF networks contributes to oncogenesis across diverse malignancies. Translating these mechanistic insights catalyzes two distinct therapeutic modalities. For VHL-deficient malignancies, selectively intercepting unshielded downstream effectors with small-molecule inhibitors provides rational, vulnerability-targeted salvage strategies. Conversely, in VHL-proficient malignancies, the exceptional chemical tractability of VHL has been repurposed by proteolysis targeting chimeras (PROTACs). VHL-recruiting PROTACs hijack operational ligase machinery to degrade targeted oncogenic drivers, including some previously \"undruggable\" oncogenes. These next-generation degraders offer potential biomarker-driven strategies to overcome current therapeutic bottlenecks in ccRCC and other associated malignancies. However, current evidence derives predominantly from in vitro and animal models. Realizing the clinical potential of VHL-targeted strategies requires addressing key unresolved questions regarding substrate directness, tissue tropism, and resistance trade-offs.

Although most patients initially respond to platinum-based chemotherapy, relapse is almost inevitable and treatment options at recurrence remain limited. The recent introduction of immune checkpoint inhibitors has provided only modest clinical benefit, largely due to the fact that these tumors are immunologically cold. These limitations highlight the urgent need to better understand the molecular features of small cell lung cancer in order to identify more effective therapeutic strategies. In this review, we summarize current knowledge of the molecular landscape of small cell lung cancer, with particular emphasis on transcriptome-based classifications that have identified four major molecular subtypes defined by distinct transcriptional regulators and gene expression programs. We discuss how these classifications have improved the biological understanding of the disease and stimulated efforts to develop subtype-specific therapeutic strategies. At the same time, we highlight important limitations of this framework, including the remarkable transcriptional plasticity of tumor cells, which allows dynamic transitions between subtypes and may contribute to therapeutic resistance. To address these challenges, we examine additional molecular features that may represent more stable vulnerabilities, including recurrent genomic alterations, such as the widespread loss of tumor suppressor genes or oncogene amplifications through extrachromosomal DNA. We also discuss emerging approaches aimed at identifying novel context-specific cancer dependencies, including genome-scale functional screens in vitro and in vivo and genetic restraint analyses. Finally, we consider the growing potential of liquid biopsy strategies, which exploit the high level of circulating tumor DNA in patients with this disease to detect clinically relevant genomic alterations and monitor tumor evolution. Overall, this review highlights both the opportunities and challenges associated with molecular stratification in small cell lung cancer.
