Within this context, the atypical Hippo signaling pathway emerges as a crucial regulatory network, integrating diverse components including core kinases (TAO kinases, MAP4K family, NDR1/2 kinases), cell polarity determinants (CRUMBS, SCRIBBLE), junctional adhesion molecules (AMOT family), phosphorylation mediators (14-3-3 proteins), and tumor suppressors (NF2, RASSF family). This multifaceted system governs fundamental cellular processes spanning proliferation, apoptosis, migratory capacity, and immune microenvironment modulation. Notably, post-translational modifications (ubiquitination, acetylation, SUMOylation) of pathway components dynamically regulate the stability and activity of downstream effectors YAP/TAZ, whose sustained activation through molecular aberrations drives tumor progression and treatment resistance in head and neck malignancies.The pathway's extensive crosstalk with Wnt signaling, NF-κB cascades, and estrogen receptor networks creates context-dependent regulatory plasticity that contributes to tumor heterogeneity. Current therapeutic innovation focuses on molecular diagnostics and precision targeting approaches, including direct YAP/TAZ-TEAD complex inhibitors, upstream receptor modulators, and rational combinations with immune checkpoint blockade. Future investigations should employ multi-omics profiling to delineate tumor subtype-specific regulatory architectures while advancing novel drug delivery platforms.

They preserve the genetic and phenotypic characteristics of the tissue of origin, and represent valuable <i>in vitro</i> models for drug screening, biomarker discovery, cell therapy and genetic modification. Importantly, PDOs reproduce the tumor behavior and can predict therapeutic responses, making them relevant for clinical applications for personalized therapies. PDOs may also be used for studying the interactions between cancer cells and the tumor microenvironment (TME). These interactions are driven by biochemical factors released by the cells, and biomechanical events such as the remodeling of the extracellular matrix (ECM). In recent years, it has become evident that the interactions between cancer cells and the TME have an impact on tumor development and on the efficacy of cancer therapy Therefore, targeting both tumor cells and the TME may improve patient response to treatment. Most PDO culture protocols are limited to epithelial cells. However, recent advances such as use of decellularized ECM (dECM) scaffolds have allowed for the development of <i>in vivo</i>-like environments that host diverse cell types, both normal and pathological, in a tridimensional (3D) manner that closely mimics the complexity of the TME. dECM-based models effectively replicate the interactions between tumor cells, ECM and the microenvironment, are easy to analyze and adaptable for drug testing. By incorporating TME components and therapeutic agents, these models offer an advanced platform for preclinical testing.</p>","PeriodicalId":12448,"journal":{"name":"Frontiers in Cell and Developmental Biology","volume":"13 ","pages":"1569337"},"PeriodicalIF":4.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12137298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144233625","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}
