KANK1 and neoplasm: The KANK1-WTPyMT tumoroids grew faster compared to KANK1-KOPyMT tumoroids (Fig. 3d, e, Supplementary Movie 1, 2) and contained significantly more Ki67+ cells at the experimental end point (Fig. 3d, f), which confirms our hypothesis that KANK1 promotes tumor growth in a cell-autonomous manner.
