					<description><![CDATA[In a groundbreaking study published in Nature, researchers have unveiled the pivotal role of specific genetic elements in preserving extrachromosomal DNA (ecDNA) within cancer cells, shedding light on a critical driver of oncogene amplification and tumor evolution. This revelation illuminates the mechanisms behind how ecDNA contributes to cancer’s aggressive growth and therapy resistance, offering fresh [&#8230;]]]></description>
