细胞新图谱揭示关键DNA对癌症进化的作用

Core Insights - The research published by the National Medical Center of Hope City, USA, reveals the critical role of extrachromosomal DNA (ecDNA) in cancer evolution, providing a foundation for future precision medicine and personalized treatment options for cancer patients [1][2] Group 1: Research Findings - The study identifies the significant role of ecDNA, which has been previously overlooked, in driving cancer development and evolution [1] - New mechanisms of interaction between different ecDNAs have been uncovered, indicating that their presence alongside certain oncogenes can lead to a hypoxic tumor microenvironment, which is linked to cancer progression and treatment resistance [1][2] Group 2: Methodology and Applications - The research combines spatial transcriptomics and genomic data to identify distinct cell populations that have acquired additional mutations from a common ancestor, aiding in the understanding of tumor evolution [2] - The study focuses on glioma samples and establishes a comprehensive analytical framework that can be referenced by other research teams, with the potential for broader application in personalized cancer treatment [2]
