The role of FAM72A in CC remains poorly defined. This study aimed to investigate its function in CC progression and its impact on the PI3K/AKT/mTOR pathway. FAM72A expression in CC was examined using TCGA-CESC and GEO (GSE63514) datasets, and then validated in CC tissues and cell lines. Functional assays assessed cell proliferation (CCK-8, EdU), invasion (Transwell), apoptosis (flow cytometry), and epithelial–mesenchymal transition (EMT; Western blot for E-cadherin/N-cadherin). The role of FAM72A in the PI3K/AKT/mTOR pathway was further evaluated by Western blot and pharmacological modulation with the activator 740 Y-P and the inhibitor LY294002. In vivo, a xenograft model with BALB/c nude mice was used to assess tumor growth, apoptosis (TUNEL staining), proliferation (Ki-67 IHC), and pathway activation (p-PI3K, p-AKT, and p-mTOR). FAM72A expression was upregulated in CC tissues and correlated with poor survival. Subgroup analysis showed that high FAM72A expression was associated with advanced FIGO stage, lymph node metastasis, and deep stromal invasion, indicating a link with aggressive clinical features. FAM72A silencing suppressed proliferation and invasion but promoted apoptosis, mainly through inhibition of the PI3K/AKT/mTOR pathway. Conversely, FAM72A overexpression enhanced these malignant traits. In vivo, FAM72A knockdown reduced tumor burden and altered EMT markers and PI3K/AKT/mTOR pathway activity. FAM72A promotes CC progression, at least in part, through activation of the PI3K/AKT/mTOR pathway, supporting its value as a potential therapeutic target.</p></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional mapping methods are resource-intensive, while remote sensing approaches depend on the availability of ground truth datasets. In this context, this study presents a novel framework for time series habitat classification. The approach leverages a single pre-existing habitat cartography and a limited set of ancillary data to derive a retrospective training dataset. The method was applied to analyse 39 years (1985–2023) of habitat and land cover changes in Gran Paradiso National Park (NW Italy). Annual seasonal composite images were generated for the growing and senescence seasons using an enhanced Best Available Pixel approach. Annually derived training datasets were used to classify hierarchically land cover and habitats via ensemble random forest models. Validation against high-resolution maps demonstrated the robustness of the approach. The method allows for long-term habitat monitoring even in data-sparse environments. The results reveal high stability of land cover (88% of the area) and significant trends in some vegetation types, including a decline in grasslands (− 10 ha year<sup>−1</sup>) and the expansion of shrublands (+ 10 ha year<sup>−1</sup>). The method proved to be reliable for large patches, less so for ecotones. Future research should explore its application across different landscapes.

Recent breakthroughs in three-dimensional tumor modeling have led to the development of brain tumor organoids, patient-derived organoids, and bioengineered tumor-on-chip systems that offer more physiologically relevant platforms for studying glioblastoma biology and therapeutic response. One of the key advancements in these models is the incorporation of vascular networks to mimic the neurovascular unit and the blood-brain barrier (BBB). Various strategies such as co-culturing with endothelial cells, bio-printing vascularized scaffolds, and utilizing microfluidic platforms have been explored to enhance vascularization within glioblastoma organoids. These models have demonstrated improved nutrient and oxygen exchange, reduced hypoxia, and better maintenance of tumor heterogeneity.
