KIF18A and cancer: It is important to note that the HCT-116 WGD+ clones did not display higher KIF18 expression compared to diploid HCT-116 cells (Cohen-Sharir et al., 2021), whereas tetraploid MCF10A cells and many WGD+ human cancers expressed higher levels of KIF18A compared to near-diploid cells and WGD− cancers (Quinton et al., 2021).
