MD/PhD @ Stanford
so much fun working on this project with Venkat, King, Ivy, and team! Read on to learn about the retention elements critical for the tethering of extrachromosomal DNA to mitotic chromosomes in cancer cells.
Our paper is out in @nature.com! Oncogenes are often copy-number amplified on extrachromosomal DNA (ecDNA) in cancer, but how is ecDNA inherited by dividing cells? Here we identified elements within ecDNA that promote its retention in dividing cells. 1/11

The ambitious state lawmaker argues moves by Elon Musk and Robert F. Kennedy Jr. show the Golden State must “step up” as a global leader.

Cancer cells often harbor oncogenes outside chromosomes on extrachromosomal DNA (ecDNA), which is unevenly inherited by dividing cells. We reported in Nature last week that collectives of ecDNAs are inherited together by dividing cancer cells. 1/
