Ploidy Leads a Molecular Motor to Walk Different Paths to Drug Resistance.

In this issue of Cell Chemical Biology, Pisa et al. (2020) find that haploid and diploid cells differentially develop resistance to the CENP-E inhibitor GSK923295. The results highlight the power of tumor cells to evade growth inhibition and potentially inform the design of next-generation CENP-E drugs to overcome resistance.
