Explore advanced computational methods for identifying extrachromosomal DNA (ecDNA) in cancer genomes through this one-hour conference talk from ICBS2025. Learn about the significance of extrachromosomal DNA as circular DNA elements that exist independently of chromosomes and their critical role in cancer progression, drug resistance, and tumor evolution. Discover cutting-edge bioinformatics approaches and algorithms used to detect these elusive genetic structures from sequencing data, including the challenges posed by their circular nature and variable copy numbers. Understand how ecDNA contributes to oncogene amplification and provides cancer cells with selective advantages, making their detection crucial for understanding tumor biology and developing targeted therapies. Gain insights into the latest research findings on ecDNA prevalence across different cancer types and their implications for precision medicine approaches in oncology.
