Current OED grading systems do not reliably predict transformation and suffer from considerable observer variability. Recent studies have highlighted that peri-epithelial lymphocytes may play an important role in OED malignant transformation, with indication that intra-epithelial lymphocytes (IELs) may also be important. We propose a novel artificial intelligence (AI) based IEL score from Haematoxylin and Eosin (H&E) stained Whole Slide Images (WSIs) of OED tissue slides. We determine the prognostic value of our IEL score on a digital dataset of 219 OED WSIs (acquired using three different scanners), compared to pathologist-led clinical grading. Our IEL scores demonstrated significant prognostic value (C-index = 0.67, p < 0.001) and were shown to improve both the binary/WHO grading systems in multivariate analyses (p < 0.001). Nuclear analyses confirmed the positive association between higher IEL scores, more severe OED and malignant transformation (p < 0.05). This underscores the potential importance of IELs, and by extension our IEL score, as prognostic indicators in OED. Further validation through prospective multi-centric studies is warranted to confirm the clinical utility of IELs.","PeriodicalId":9243,"journal":{"name":"British Journal of Cancer","volume":"132 2","pages":"168-179"},"PeriodicalIF":6.4,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41416-024-02916-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142766350","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}

PDAC spheroid models and organoids were used to assess the combination effects. Tumour growth and the immune and fibrotic microenvironment were evaluated by immunohistochemistry, single-cell analysis and spatial proteomics in patient-derived xenograft (PDX) and orthotopic immunocompetent KPC mouse models. The FOLFIRINOX and VE-822 combination had a strong synergistic effect in several PDAC cell lines, whatever their BRCA1, BRCA2 and ATM mutation status and resistance to standard chemotherapy agents. This was associated with high DNA damage and inhibition of DNA repair signalling pathways, leading to increased apoptosis. In immunocompetent and PDX mouse models of PDAC, the combination inhibited tumour growth more effectively than FOLFIRINOX alone. This was associated with tumour microenvironment remodelling, particularly decreased proportion of fibroblast activated protein-positive CAFs and increased anti-tumorigenic immune cell infiltration and interaction. The FOLFIRINOX and VE-822 combination is a promising strategy to improve FOLFIRINOX efficacy and overcome drug resistance in PDAC.","PeriodicalId":9243,"journal":{"name":"British Journal of Cancer","volume":"132 2","pages":"222-235"},"PeriodicalIF":6.4,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142754558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NWO was defined as participants with a normal BMI (18.5–24.9 kg/m2) and an excess percent body fat (PBF > 33.3%). Cox proportional hazard models were used to investigate the associations of NWO and NWO-related biomarkers with incident breast cancer. NWO was not associated with premenopausal breast cancer, whereas it was associated with a higher risk of postmenopausal breast cancer (hazard ratio = 1.19, 95% CI: 1.08–1.31). In our meta-analysis, per 5-unit increment in percent body fat level was linked to a 15% (95% CI: 10–19%) elevated risk of postmenopausal breast cancer in females with normal BMI. Stratified analyses showed a stronger positive association in females with higher genetic risk. In our NWO-biomarkers analyses, NWO was linked to 34 identified biomarkers, of which three inflammation markers (monocyte count, neutrophil count, and C-reactive protein), and one ketone body metabolite (β-Hydroxybutyrate) also indicated a positive association with postmenopausal breast cancer. NWO is associated with an increased risk of postmenopausal breast cancer, indicating that relying solely on BMI neglects the higher risk faced by non-obese postmenopausal women.","PeriodicalId":9243,"journal":{"name":"British Journal of Cancer","volume":"132 2","pages":"203-211"},"PeriodicalIF":6.4,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41416-024-02906-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142750040","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}

Mesenchymal stem cells (MSCs) modulate immunity via IDO but also suppress IFN-γ. While MSC IDO induction by IFN-γ is established, other drivers in this immunosuppressive setting remain unknown. Human bone marrow mesenchymal stem cells (MSCs) with IDO or IL-10RA knockdown were co-cultured with healthy donor T cells to assess immunosuppression. PDAC organoid anticancer activity was also tested in these co-cultures. Co-culturing MSCs with T cells in an IL-10RA-enriched environment enhances IDO expression, resulting in T cell suppression. Moreover, IL-10RA-positive MSCs collected from co-cultures with IL-10 supplementation show increased IDO expression. Conversely, MSCs with IL-10RA knockdown exhibit a significant reduction in IDO RNA and protein expression, as well as STAT3 phosphorylation status, which is a known upstream signalling pathway in IDO gene regulation, in T cell co-cultures. Down-regulation of IL-10RA also inhibits IDO activity in MSCs, resulting in reduced T cell suppression, and enabling the co-cultured T cells to kill PDAC organoids. Our research reveals IL-10RA as a pharmacological target in stromal cells for enhancing T cell-mediated PDAC eradication by downregulating IDO via blocked IL-10/IL-10RA signalling in MSCs. This advances IL-10RA interference in the tumour microenvironment (TME) to restore T cell cytotoxicity against cancers.","PeriodicalId":9243,"journal":{"name":"British Journal of Cancer","volume":"132 1","pages":"126-136"},"PeriodicalIF":6.4,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41416-024-02893-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142726113","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}

SKP2 induced protein degradation of CDC6 and CDT1 through the ubiquitin-proteasome pathway. Conversely, SKP2 inhibition elevated CDC6 and CDT1 protein levels, which caused DNA aberrant replication, DNA damage and genomic instability, thereby resulting in the accumulation of cytosolic DNA, activating cGAS/STING signaling pathway and improving antitumor immunity.
