However, the biological function of most circRNAs in liver metastasis of CRC is still unknown. In this study, we identified differentially expressed circRNAs associated with liver metastasis (LM-DE-circRNAs). A total of 247 LM-DE-circRNAs were identified, and crucial signaling pathways, including the regulation of actin cytoskeleton, were significantly enriched, featuring six LM-DE-circRNAs. Notably, circDIAPH1 (hsa_circ_0074323), with the highest AUC value, emerged as a potential biomarker for CRC liver metastasis (CRLM). Functional assays following circDIAPH1 knockdown demonstrated induced apoptosis, suppressed proliferation, reduced metastasis, and invasion in CRC cell lines in vitro. The circDIAPH1 knockdown attenuated tumor growth in a cell-derived xenograft model. Furthermore, circDIAPH1 knockdown lessened the liver metastasis. Transcriptome profiling revealed that CEACAM6 was the most downregulated gene while circDIAPH1 was knocked down, and possesses high expression value in CRC. Most importantly, we found that circDIAPH1 recruited transcription factor FOXA1 to bind in the promoter region of CEACAM6 and initiated CEACAM6 expression. Additionally, the study identified the transcription factor BRD4 as a regulator of circDIAPH1 expression in CRC.

However, the effects of Sop on cancer progression have not been systemically investigated. In this study, we performed a comprehensive investigation of Sop's function in GBM using colony formation and Transwell assays in vitro, along with subcutaneous xenograft tumor analysis in vivo. We employed RNA sequencing and bioinformatics analysis in conjunction with Western blotting (WB) and reverse transcription-quantitative polymerase chain reaction (RT-PCR) to explore the underlying mechanism. Our results demonstrated that Sop suppressed U251 cell proliferation and metastasis in vitro and inhibited the tumorigenic behavior of U251 cells in vivo. Further investigations revealed a positive correlation between the levels of activated AMP-activated protein kinase (AMPK) and Sop treatment; notably the application of the AMPK inhibitor, compound C (CC), abolished inhibitory effects of Sop on the malignant phenotype of U251 cells.

It was found that the expression of HADHB in ccRCC tumor tissues was lower than that in paracancer tissues, which is associated with poor patient prognosis. Subsequently, we confirmed that highly invasive ccRCC exhibited an increased lipid accumulation due to the suppression of mitochondrial fatty acid transport and enhanced conversion of fatty acids to triglycerides within cancer cells. Specifically, the downregulation of HADHB inhibited mitochondrial fatty acid β-oxidation (FAO) in cancer cells, leading to partial impairment of mitochondrial function and decreased ATP production. However, this trade-off involving the reduction of a high-yield ATP production conferred an advantage by reducing reactive oxygen species (ROS) generation within cancer cells, thereby protecting them from oxidative stress and enhancing their invasive potential.

Current therapies often fail due to the emergence of drug resistance mechanisms, such as those involving anti-apoptotic pathways and immune evasion, highlighting an urgent need for novel approaches to overcome these limitations. Programmed cell death (PCD) is crucial for tissue homeostasis, with PANoptosis-a form of PCD integrating pyroptosis, apoptosis, and necroptosis-recently identified. This process, regulated by the PANoptosome complex, could be key to overcoming AML drug resistance. Targeting multiple PCD pathways simultaneously may prove more effective than single-target therapies. Research suggests that disrupting anti-apoptotic mechanisms, such as those involving Bcl-2, can enhance drug sensitivity in AML. This study hypothesizes that PANoptosis-associated resistance genes (PARGs) play a critical role in AML drug resistance by modulating immune responses and offers a multi-faceted approach to tackle this challenge. Using RNA sequencing data from the Cancer Genome Atlas and Gene Expression Omnibus databases, we performed differential expression analysis to identify significantly dysregulated PARGs in AML. Regression analysis identified prognostic PARGs, bridging a key gap in understanding how these genes contribute to treatment resistance. We then verified their expression in AML cell lines and cell samples treated with cytarabine using RT-qPCR. Hierarchical clustering revealed distinct PARG expression patterns, and functional enrichment analysis highlighted their involvement in immune-related pathways. The combination of bioinformatics and experimental validation underscores how these genes may mediate immune modulation in drug resistance, providing a robust framework for further study. Our findings suggest that PARGs contribute to AML resistance by modulating immune responses and provide potential targets for therapeutic intervention. This study highlights the potential of targeting PARGs to improve treatment outcomes in AML. By analyzing the expression changes of these genes in response to standard clinical treatments, we provide a framework for developing multi-target therapeutic strategies that simultaneously disrupt multiple programmed cell death pathways. Such an approach directly addresses the limitations of current treatments by offering a method to enhance drug sensitivity and mitigate resistance, potentially improving survival rates. Our findings underscore the importance of a comprehensive understanding of PCD mechanisms and pave the way for innovative treatments that could significantly impact AML management.</p>","PeriodicalId":19003,"journal":{"name":"Molecular Carcinogenesis","volume":" ","pages":"801-815"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143046938","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}

This disease includes multiple subtypes, each with unique biological features and treatment responses. Despite significant advancements in detection and therapy, challenges remain, particularly in managing aggressive forms like triple-negative breast cancer and overcoming drug resistance. Breast cancer classification and subtype determination are typically performed by immunohistochemistry (IHC) method, which assesses four key markers (ER, PR, HER2, KI67); however, due to the recognized issues with this approach-especially regarding the evaluation of Ki67-there is a risk of misclassification. Patients who may be suitable for chemotherapy could miss possible advantages and only experience needless toxicity as a result of improper treatment decisions. Molecular profiling has improved breast cancer management, enabling the creation of multigene prognostic tests (MPTs) like Oncotype Dx, MammaPrint, Prosigna, Endopredict, and Breast Cancer Index which assess gene expression profiles to more accurately predict recurrence risks. These tools help personalize treatment, identifying patients who can avoid chemotherapy and/or extended endocrine therapy. While many MPTs are available, only Oncotype Dx and MammaPrint have prospective validation, with Prosigna providing additional prognostic insights by incorporating clinical variables. Molecular tests are especially usefull in the \"gray zone,\" which includes tumors measuring between 1 and 3 cm with 0-3 positive lymph nodes and an intermediate proliferation index. However, their clinical utility has not been definitively established, and significant differences exist between them. This article provides an in-depth analysis of established genomic assays, including testing procedures, clinical validity, utility, diagnostic frameworks, and methodologies. Our comparison aims to improve early breast cancer management by guiding pathologists and oncologists in optimizing the use of genomic assays in clinical practice. By presenting this information, we aim to enhance understanding of the clinical utility and effectiveness of these assays, supporting the development of personalized treatment strategies for early breast cancer patients. Genomic assays offer important insights that can support treatment decisions in early-stage breast cancer, especially when used alongside other clinical evaluations, predictive tools, and management guidelines. While multiple gene expression profiling tests are available, they classify patients differently and are not interchangeable; therefore, their application should be at the clinician's discretion during the decision-making process. It is essential that these tests are not the sole factor in determining the best treatment plan: other clinical considerations and patient preferences should also play a significant role in guiding treatment decisions.</p>","PeriodicalId":19003,"journal":{"name":"Molecular Carcinogenesis","volume":" ","pages":"789-800"},"PeriodicalIF":3.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441532","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}
