As high-resolution imaging is often limited by cost, super-resolution methods provide a practical alternative with only low-resolution data. However, existing methods generally suffer from artifacts, oversmoothing, and slow inference speed. In this study, we developed a hierarchal deep learning framework based on local pathological image patterns, named Hierarchical Local Image Patterns (HLIP), to achieve accurate, high-fidelity, and real-time super resolution with flexible magnifications. HLIP integrates semantic features with both pixel- and morphology-level features and reconstructs super-resolution images by the recognized local pathological image patterns. Benchmark analysis showed HLIP achieved the best performance and robustness on both internal and external test datasets. The generated super-resolution images contain abundant pathological details and maintain high fidelity. HLIP can be used for the enhancement of other models across multiple clinical scenarios, including gland segmentation, cell segmentation, Helicobacter pylori detection, and therapy response prediction. With its superior performance in pathology image super resolution, HLIP offers a versatile tool for image preprocessing in computer-aided systems, thereby supporting accurate diagnosis in clinical practice. © 2025 The Pathological Society of Great Britain and Ireland.</p>","PeriodicalId":232,"journal":{"name":"The Journal of Pathology","volume":" ","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TP53 mutations are common in gastric tumorigenesis; however, nearly half of the gastric cancers (GCs) remain wildtype TP53 (TP53_WT). We investigated epigenetic/genetic profiles of GCs and the carcinogenic mechanisms underlying GCs with TP53_WT. Comprehensive DNA methylation analysis revealed four DNA methylation epigenotypes (MEs) in GCs, namely, high ME (HME), extremely HME (E-HME), low ME (LME), and extremely LME (E-LME). E-HME matched Epstein-Barr virus (EBV)-positive GC (E-HME/EBV). HME can be further categorised into MLH1-deficient (HME_MLH1(-)) and -proficient cases. The Cancer Genome Atlas data confirmed that HME_MLH1(-)/microsatellite instability (MSI) and E-HME/EBV cases significantly retained TP53_WT and had higher MDM2 expression levels than other MEs. We hypothesised that apoptosis pathways in TP53_WT GC may be suppressed post-transcriptionally by activated MDM2. Short hairpin RNA-mediated MDM2 knockdown and the p53-MDM2 inhibitors, nutlin-3 and RG7388, induced apoptosis in TP53_WT GC cells, indicating that activated MDM2 suppressed p53 protein levels and thereby attenuated the downstream p53 pathway activation, which was restored upon MDM2 knockdown or inhibitor treatment. Collectively, DNA-hypermethylated GC cases, HME_MLH1(-)/MSI and E-HME/EBV, follow a unique carcinogenic pathway to evade apoptosis in the absence of TP53 mutation, potentially making them responsive to therapeutic strategies that function primarily through the p53 pathway. © 2025 The Pathological Society of Great Britain and Ireland.</p>","PeriodicalId":232,"journal":{"name":"The Journal of Pathology","volume":" ","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reviewed 31 cases of TdT-positive LBCL and B-ALL/LBL, and their final diagnosis included 19 diffuse large/high-grade BCLs with MYC and BCL2 rearrangements (five DLBCL-MYC/BCL2, 14 HGBCL-MYC/BCL2), three DLBCL not otherwise specified (NOS), three HGBCL-NOS, four B-ALL/LBL, and two unclassifiable cases. TdT was variably expressed in all these cases, without any clear demarcation among different groups. Loss or partial loss of CD20 expression was seen in 13/17 DLBCL/HGBCL-MYC/BCL2, 2/3 HGBCL-NOS, and 2/2 unclassified, albeit not in DLBCL-NOS. Expression of BCL6 and/or MUM1 was seen in 3/4 B-ALL/LBLs and 2/2 unclassified. Next-generation sequencing revealed characteristic mutations associated with follicular lymphoma and its high-grade transformation in each DLBCL/HGBCL-MYC/BCL2, and also frequent variants in genes targeted by somatic hypermutation (SHM) in almost all DLBCL/HGBCL-MYC/BCL2, DLBCL-NOS, and HGBCL-NOS but one case. In contrast, such mutations were absent in B-ALL/LBL. There were no pathognomonic mutations in the two unclassifiable cases, although one showed a moderate level of somatic mutations in its rearranged IGHV. Furthermore, in three cases of TdT-positive HGBCL-MYC/BCL2, studies of previous or concurrent follicular lymphoma demonstrated their divergent evolution from an IGH::BCL2-positive cell population following acquisition of MYC translocation. In conclusion, mutation profiling analysis including the SHM target genes is highly valuable in the differential diagnosis between TdT-positive LBCL and B-ALL/LBL. © 2025 The Author(s).

The tumor suppressor gene BRCA1 has multiple functions that include secondary processes cooperating with its main function as a caretaker of genomic integrity. BRCA1 is often mutated in breast and ovarian cancer, but BRCA1 mutations are also associated with PCa, although they are less frequently observed. Most PCa patients do not, however, carry BRCA1 mutations, and interestingly, it has been shown that BRCA1 expression is enriched in castration-resistant PCa. In this study we elucidated the prostate tissue-specific role of the BRCA1 protein. Although the regulation of DNA damage response genes has been studied in PCa, comprehensive analyses of BRCA1 regulation in the context of androgen signaling are lacking. Our results indicate that BRCA1 is dynamically regulated by AR signaling and that activation of AR via its natural ligand, dihydrotestosterone, represses BRCA1 expression. Our analyses both in vitro and of patient samples and mouse xenografts showed that BRCA1 expression was induced and sustained after androgen deprivation. Moreover, we observed that oxidative stress-related pathways were regulated by BRCA1 in PCa cells and that androgen deprivation therapy-induced activation of BRCA1 supported the function of NRF2, the master regulator of antioxidant defense, and a known interactor of BRCA1. Impaired NRF2 activity, in the absence of BRCA1, decreased growth in a 3D environment. Our findings shed light on the functional role of BRCA1 protein in PCa and suggest that BRCA1 is regulated by the evolving AR signaling state during PCa progression. Thus, AR-mediated suppression of BRCA1 accumulates oncogenic alterations in the early phases of PCa tumor progression and safeguards from excessive reactive oxygen species (ROS) when upregulated during androgen deprivation therapy. © 2025 The Author(s).

As the susceptibility of acquiring a SARS-CoV-2 infection in COPD remains unclear, this study explored the airway expression of SARS-CoV-2 entry-associated proteins in the lungs of COPD patients in comparison to non-COPD controls. Immunohistochemical staining of lung tissue was performed to investigate the expression profiles of SARS-CoV-2 entry-associated proteins in the bronchial epithelium of 27 COPD patients and 40 non-COPD controls. In addition, the associations between these expression profiles with lung function in COPD patients and smoking status in non-COPD controls were examined. COPD patients demonstrated smoking-independent lower expression of HSPA5, NRP1, BSG, TMPRSS2, and ITGB6 in airway epithelium as compared to non-COPD controls. No significant differences were observed for Furin, CTSL, ADAM17, and ITGA5. BSG percentage area expression was significantly negatively associated with lung function in COPD patients. Moreover, the study revealed smoking-associated differences for Furin, HSPA5, ADAM17, BSG, ITGA5, and ITGB6 within non-COPD controls, with lower airway epithelial expression (except for Furin) in ever-smokers than in never-smokers. To conclude, this study showed a lower expression of a specific set of SARS-CoV-2 entry-associated proteins in the bronchial epithelium of COPD patients compared with non-COPD controls, while other factors showed similar expression levels. The consequences of these findings on COVID-19 susceptibility remain uncertain. Although reduced expression of entry factors may suggest less cellular availability for viral entry, it could be speculated that the similar expression levels of other factors, together with impaired airway clearance in COPD, may still facilitate infection, thereby providing potential mechanistic insight into COVID-19 susceptibility in this patient population. © 2025 The Author(s).

We developed a patient-derived urologic tumor fragment (PDUTF) platform comprising 56 tumors and constructed three major urological tumor tissue microarrays from 356 patients. Analyzed using the PDUTF platform and tissue microarrays (TMAs), we found that tumors with KMT2D deficiency were associated with enhanced T-cell activation in response to anti-PD-1 therapy and exhibited increased T-cell infiltration. Subsequently, T-cell migration and T-cell-mediated tumor cell killing assays revealed that the deletion of KMT2D in cancer cells promoted CD8<sup>+</sup> T-cell migration and cytotoxicity against tumor cells. Mechanistically, the loss of KMT2D enhanced antitumor immunity by promoting chemokine-mediated recruitment of T cells both in vitro and in vivo. Finally, the small-molecule inhibitor MI-503 combined with anti-PD-1 therapy suppressed tumor growth on the PDUTF platform.

{"title":"Tracing metastatic spread in pediatric solid tumors using copy number and targeted deep sequencing","authors":"Natalie Andersson,&nbsp;Michele Ferro,&nbsp;Caroline Jansson,&nbsp;Subhayan Chattopadhyay,&nbsp;Jenny Karlsson,&nbsp;David Gisselsson","doi":"10.1002/path.6472","DOIUrl":"10.1002/path.6472","url":null,"abstract":"<p>The most common cause of death in pediatric cancer patients is a treatment-resistant tumor, compounded by metastatic spread, making surgery, radiation therapy, and chemotherapy unfeasible as curative treatment options. However, the mechanisms behind metastatic spread in pediatric tumors remain largely unexplored. We conducted whole-genome copy number profiling on 171 primary tumor and metastases samples from 17 patients with neuroblastoma, Wilms tumor, or gonadal tumors, and performed targeted deep sequencing on a subset. Phylogenetic reconstruction enabled spatiotemporal tracking of subclones. In total, 11 of 17 patients displayed at least one metastasis arising earlier, defined as occurring before the most recent common ancestor in the primary tumor. In eight patients, metastatic spread was observed several times during tumor evolution, with different subclones from the same primary tumor having metastatic capability, even colonizing the same site. Strikingly, dissemination between metastases (intermetastatic spread) occurred in eight of nine patients with metastases in at least two different sites, indicating that this is a common phenomenon in pediatric malignancy. © 2025 The Author(s). <i>The Journal of Pathology</i> published by John Wiley &amp; Sons Ltd on behalf of The Pathological Society of Great Britain and Ireland.</p>","PeriodicalId":232,"journal":{"name":"The Journal of Pathology","volume":"267 3","pages":"347-365"},"PeriodicalIF":5.2,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pathsocjournals.onlinelibrary.wiley.com/doi/epdf/10.1002/path.6472","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145124123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
