Parallel advances in artificial intelligence (AI), particularly in pattern recognition, feature extraction and predictive modelling, now offer unprecedented opportunities to translate these insights into clinical applications. Here, we propose single-cell -omics-based Disease Predictor through AI (scDisPreAI), a unified framework that leverages AI to integrate single-cell -omics data, enabling robust disease and disease-stage prediction, alongside biomarker discovery. The foundation of scDisPreAI lies in assembling a large, standardised database spanning diverse diseases and multiple disease stages. Rigorous data preprocessing, including normalisation and batch effect correction, ensures that biological rather than technical variation drives downstream models. Machine learning pipelines or deep learning architectures can then be trained in a multi-task fashion, classifying both disease identity and disease stage. Crucially, interpretability techniques such as SHapley Additive exPlanations (SHAP) values or attention weights pinpoint the genes most influential for these predictions, highlighting biomarkers that may be shared across diseases or disease stages. By consolidating predictive modelling with interpretable biomarker identification, scDisPreAI may be deployed as a clinical decision assistant, flagging potential therapeutic targets for drug repurposing and guiding tailored treatments. In this editorial, we propose the technical and methodological roadmap for scDisPreAI and emphasises future directions, including the incorporation of multi-omics, standardised protocols and prospective clinical validation, to fully harness the transformative potential of single-cell AI in precision medicine.</p>","PeriodicalId":10189,"journal":{"name":"Clinical and Translational Medicine","volume":"15 4","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ctm2.70290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prognostic and therapeutic relevance of the IFGRNS score was assessed across cancer types, considering tumor pathology, genomic alterations, tumor mutation burden, and microenvironment.

The prognostic significance of the score was influenced by factors such as cancer type, tumor pathology, and the tumor microenvironment. Single-cell analysis revealed that myeloid cells, particularly the M2 macrophage subtype, demonstrated high levels of IFGRNS expression, which was associated with tumor progression. A negative correlation was observed between the IFGRNS score and outcomes to anti-PD1 immunotherapy in urologic cancers, where patients with higher scores showed worse prognosis and lower response rates to therapy.

Here, we outline our recently discovered mechanism by which energy-dense diets induce hepatocyte senescence, previously presumed to prevent HCC progression. Using fructose and fat-rich diets we found diet-induced hepatocyte single-strand DNA breaks that lead to activation of the DNA damage response (DDR), which culminates in the activation of TP53 and induction of its targets p21&lt;sup&gt;CIP1&lt;/sup&gt; and p16&lt;sup&gt;INK4a&lt;/sup&gt;, two cell-cycle inhibitors that enter DNA damaged hepatocytes into senescence, a state during which they cannot proliferate. Interestingly, we found that TP53 also leads to the induction of the metabolic enzyme FBP1, which we previously identified as an AKT inhibitor due to its ability to interact with both AKT and PP2A catalytic subunit, which inactivates AKT.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; By inhibiting AKT, FBP1 which also acts as an HCC-specific tumour suppressor,&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; leads to stabilization of TP53, thereby boosting hepatocyte senescence&lt;span&gt;&lt;sup&gt;5&lt;/sup&gt;&lt;/span&gt; (Figure 1). FBP1 is upregulated during MASH, but as MASH progresses to HCC FBP1 is degraded and leads to activation of AKT, in insulin and growth factor-stimulated hepatocytes. By phosphorylating MDM2 and enhancing its ability to induce TP53 degradation,&lt;span&gt;&lt;sup&gt;6&lt;/sup&gt;&lt;/span&gt; the downregulation of FBP1 also leads to TP53 deficiency, thereby allowing senescent hepatocytes to re-enter the cell cycle. Conversely, the upregulation of FBP1 in response to energy-dense and DNA-damaging diets inhibits the phosphorylation of GSK3α/β, thereby increasing the substrate binding activity of these kinases which phosphorylate NRF2 and β-catenin and thereby triggering their degradation, resulting in low NRF2 expression in senescent hepatocytes.&lt;span&gt;&lt;sup&gt;5&lt;/sup&gt;&lt;/span&gt; However, sustained metabolic stress and autophagy disruption lead to accumulation of p62/SQSTM1 which sequesters the major negative regulator of NRF2, KEAP1. This results in NRF2 activation, which induces the expression of ERK1/2-activating EGF and PDGF family members and phosphorylation-directed and TRIM28-dependent FBP1 degradation (Figure 1). FBP1 degradation, as discussed above, also results in TP53 degradation.&lt;/p&gt;&lt;p&gt;On the one hand, after oncogene activation, senescence-induced immune surveillance by CD8&lt;sup&gt;+&lt;/sup&gt; T cells clears premalignant cells and inhibits liver tumorigenesis.&lt;span&gt;&lt;sup&gt;7&lt;/sup&gt;&lt;/span&gt; However, MASH is associated with liver fibrosis driven by transforming growth factor-β, whic","PeriodicalId":10189,"journal":{"name":"Clinical and Translational Medicine","volume":"15 4","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ctm2.70293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, our research suggests that the inhibition of BORA could offer a novel strategy for improving OC prognosis.&lt;/p&gt;&lt;p&gt;OC is the most lethal gynaecologic malignancy given that most patients are diagnosed at advanced stages, when the disease has already metastasized, and the 5-year survival rate is below 30%.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; The most common and aggressive subtype is high-grade serous carcinoma (HGSC), which is a highly heterogeneous tumour generally chemoresistant.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Polo-like kinase 1 (PLK1), a master regulator of mitosis,&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; is responsible for triggering EMT in various cancers by activating multiple signalling pathways (Figure S1).&lt;span&gt;&lt;sup&gt;4, 5&lt;/sup&gt;&lt;/span&gt; Although several PLK1 inhibitors have been developed, their antitumour activity against solid tumours is modest, primarily due to poor selectivity and toxicity arising from targeting other PLK family members.&lt;span&gt;&lt;sup&gt;6, 7&lt;/sup&gt;&lt;/span&gt; Notably, BORA, a specific cofactor of PLK1, has emerged as a potential target for selectively blocking PLK1 activity. BORA activates PLK1 by binding it, causing a conformational change that enables Aurora A to phosphorylate PLK1 at T210, initiating mitotic entry.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; We propose that BORA not only activates PLK1 to trigger mitosis but also to induce EMT.&lt;/p&gt;&lt;p&gt;Previous results from our group demonstrated that BORA expression is higher in OC metastatic samples than in paired primary tumours.&lt;span&gt;&lt;sup&gt;8&lt;/sup&gt;&lt;/span&gt; In the present study, we confirmed that BORA mRNA expression (GSE73168) was higher in ascitic fluid-derived OC cells than in the matched primary tumours (Figure S2). Transcriptomic analyses were performed to elucidate BORA mechanism of action. In vivo overexpression of BORA (BORA_OE) in SKOV3 OC xenografts led to an enrichment of genes associated with EMT and migration (Figure 1A,B). Significantly upregulated genes included the main mesenchymal marker N-cadherin (&lt;i&gt;CDH2&lt;/i&gt;) and several matrix metalloproteases (e.g., &lt;i&gt;MMP13&lt;/i&gt;) (Figure 1B). The correlation between BORA mRNA expression and the expression of several metastasis-associated genes was validated in the ovarian serous cystadenocarcinoma TCGA cohort (2022-v32) (Figure S3D–G).&lt;/p&gt;&lt;p&gt;To confirm whether the gene expression deregulation produced by BORA_OE generated a mesenchymal phenotype, we compared BORA_OE cells with control cells treated with TGFβ, a well-known EMT inducer. Our results showed that, under both conditions, the mRNA levels of the mesenchymal markers ZEB1, SNAI2, MMP13, and LAMA1 were markedly increased, whereas the expression of the epithelial marker CDH1 was reduced (Figure 1C).

This study uncovers PCIF1 as a critical driver of OSCC progression via m6Am RNA modification, leading to translational repression of the tumour suppressor MTF2. Our results demonstrate that PCIF1 selectively suppresses MTF2 translation, activating oncogenic pathways that promote OSCC growth. In vitro and in vivo models confirm that PCIF1 knockdown reduces OSCC progression, whereas MTF2 knockdown counteracts this effect, highlighting the importance of the PCIF1-MTF2 axis. Clinical analyses further reveal that high PCIF1 expression and low MTF2 expression correlate with advanced tumour stage, poor treatment response and decreased overall survival. Furthermore, in a preclinical mouse model, PCIF1 knockout enhanced the efficacy of anti-PD1 immunotherapy, reducing tumour burden and improving histological outcomes. Notably, flow cytometry analysis indicated that PCIF1 primarily exerts its effects through tumour-intrinsic mechanisms rather than direct modulation of the immune microenvironment, distinguishing its mode of action from PD1 blockade. These findings establish PCIF1 and MTF2 as promising prognostic markers and therapeutic targets for OSCC, offering new avenues for treatment strategies and patient stratification.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Key points</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>PCIF1 promotes OSCC progression via m6Am methylation at the MTF2 mRNA 5′ cap.</li>\u0000 \u0000 <li>m6Am methylation suppresses MTF2 translation, enhancing tumour cell proliferation and invasion.</li>\u0000 \u0000 <li>Targeting PCIF1 holds therapeutic potential for OSCC treatment.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":10189,"journal":{"name":"Clinical and Translational Medicine","volume":"15 4","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ctm2.70286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
