NUAK1 and cancer: Immunofluorescent γ‐tubulin staining showed significantly more cells exhibiting supernumerary centrosomes 24 h after activation of CreERT2 and deletion of Nuak1, compared with EtOH‐treated controls (Fig. 3D), showing that NUAK1 regulates centrosome number in untransformed fibroblasts as well as in cancer cells.
