Cancer lethality arises from the emergence of therapeutic resistance in the face of an increasing array of drugs and novel regimens targeting everything from proliferation, DNA integrity, metabolism, cell contacts, and more. Our group studies an underappreciated endocycling cancer cell state that contributes to therapeutic resistance in numerous cancer settings. Cells in this state uncouple DNA replication from cell division to obtain abnormally high genomic count and cell size (>70x volume).
We work on a human prostate cancer cell line, chosen because the cells readily become refractory to treatment. Utilizing the Evercode WT v2 assay, we profiled untreated cancer cells alongside those in the cancer cell state. Our first dataset successfully captured the dramatically increased RNA content and provided insight into multiple cell state trajectories after chemotherapy induction.
