However, the breast cancer classification faced difficulties in scalability, fixed-size input images, and overfitting on limited datasets. To tackle these issues, this work proposes a Patho-Net model for breast cancer classification that overcomes the problems of scalability in color normalization, integrates the Gated Recurrent Unit (GRU) network with the U-Net architecture to process images without the need for resizing and computational efficiency, and addresses the overfitting problems. The proposed model collects and normalizes histopathology images using automated reference image selection with the Reinhard method for color standardization. Also, the Enhanced Adaptive Non-Local Means (EANLM) filtering is utilized for noise removal to preserve image features. These preprocessed images undergo semantic segmentation to isolate specific parts of an image, followed by feature extraction using an Improved Gray Level Co-occurrence Matrix (I-GLCM) to reveal fine patterns and textures in images. These features serve as input into the classification U-Net model integrated with GRU networks to improve the model performance. Finally, the classification result is expanded, and XAI is used for clear visual explanations of the model's predictions. The proposed Patho-Net model, which uses the 100X BreakHis dataset, achieves an accuracy of 98.90% in the classification of breast cancer.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"15 2","pages":"754-768"},"PeriodicalIF":3.6,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11897615/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143623224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GDF15 was overexpressed to determine its effect on the viability, migration, and response of EOC cells to gemcitabine, carboplatin, and paclitaxel. Reprogramming of glucose and cholesterol metabolism in EOC cells was evaluated based on oxygen consumption, lactic acid production, complex I activity, and free and esterified cholesterol levels. The activities of ATP-binding cassette (ABC)B1 and ABCC1 were assessed based on the expulsion efficiency of rhodamine 12. GDF15 overexpression promoted cell viability, migration, and resistance to gemcitabine. In addition, GDF15 induced glycolysis and increased cholesterol levels in EOC cells. Cholesterol metabolism regulated by GDF15 contributed to the resistance of EOC cells to gemcitabine by elevating ABCB1 and ABCC1 levels in lipid rafts. DHCR24 plays an important role in cholesterol synthesis. DHCR24 was identified as a downstream effector of GDF15, because knockdown of DHCR24, but not treatment with statins, suppressed the cancer-promoting effect of GDF15. Overall, GDF15 promoted the resistance of EOC cells to gemcitabine via DHCR24-mediated cholesterol metabolism to elevate ABCB1 and ABCC1 levels in lipid rafts.

Overall, 41 patients with stage IB-IVB cervical cancer were included.
