Additionally, it will focus on implications for new therapeutic strategies targeting Epithelial-Mesenchymal Transition (EMT). The colonic crypt is a highly structured epithelial unit that functions in maintaining homeostasis through a complex physiological function of diverse cell types: SCs, transit-amplifying (TA) progenitors, goblet cells, absorptive colonocytes, Paneth-like cells, M cells, tuft cells, and enteroendocrine cells. These cellular subpopulations are spatially organized and regulated by multiple crucial signaling pathways, including WNT, Notch, Bone Morphogenetic Protein (BMP), and Fibroblast Growth Factor (FGF). Specifically, we discuss how these regulatory networks control the precise locations and functions of crypt cell types that are necessary to achieve cellular organization and homeostasis in the normal colon crypt. In addition, we detail how the crypt's hierarchical structure is profoundly perturbed in colorectal cancer (CRC) development. Tumorigenesis appears to be driven by LGR5+ cancer stem cells (CSCs) and the hyperproliferation of TA cells as colonocytes undergo metabolic reprogramming. Goblet cells lose their secretory phenotype, while REG4+ Paneth-like cells foster SC niches. Tumor microenvironment is also disrupted by upregulation of M cells and by tumor-immune crosstalk that is promoted by tuft cell expansion. Moreover, the presence of enteroendocrine cells in CRC has been implicated in treatment resistance due to its contribution to tumor heterogeneity. These cellular changes are caused by the disruption of homeostasis signaling whereby: overactivation of WNT/β-catenin promotes stemness, dysregulation of Notch inhibits differentiation, suppression of BMP promotes hyperproliferation, and imbalance of FGF/WNT/BMP/NOTCH enhances cellular plasticity and invasion. Further discussion of emerging therapies targeting epithelial markers and regulatory factors, emphasizing current development in novel, precision-based approaches in CRC treatment is also included.</p>","PeriodicalId":9743,"journal":{"name":"Cells","volume":"14 18","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12468274/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145148228","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}

Here, we demonstrate that PA2G4 is essential for MYCN-driven tumor growth in neuroblastoma in vivo. Moreover, PA2G4 elevates c-MYC protein levels in neuroblastoma cells by inhibiting its ubiquitin-mediated degradation. In turn, c-MYC upregulates the transcription and protein expression of PA2G4, creating an oncogenic feed-forward expression loop. A small molecule PA2G4 inhibitor, WS6, directly disrupts the PA2G4-c-MYC protein-protein interaction, resulting in decreased levels of both PA2G4 and c-MYC.

A significant factor in the colonization of the upper digestive system is the helical shape of <i>H. pylori</i>. This helical form is maintained by a complex network of peptidoglycan (PG)-modifying enzymes and cytoskeletal proteins. Among these, the D,D-endopeptidase Csd2 plays a central role, working in conjunction with other cell shape-determining (Csd) proteins. Csd1 and Csd2 have been categorized as members of the M23B metallopeptidase family. These enzymes are classified as D,D-endopeptidases, and their function involves the cleavage of the D-Ala4-mDAP3 bond, which is present in the cross-linked di-mer muropeptides. Despite the fact that the structure of the Csd1:Csd2 complex has been examined via biochemical methods, information on the in vivo localization and dynamics of D,D-endopeptidases is still missing. Here, we use an approach that employs sophisticated different microscopy methods to visualize the spatial temporal localization and dynamics of Csd2, involving both structured illumination microscopy and single-molecule tracking. Our findings thus contribute to refining the existing model for this cellular complex by revealing curvature-dependent spatial organization and temporal dynamics underlying peptidoglycan remodeling processes essential for helical cell shape formation and maintenance.
