CEP55 and neoplasm: Engrafting a partial CEP55‐knockdown MDA‐MB‐231 derivative (sh#2) showed a significant reduction in tumor growth while a near‐complete CEP55 reduction (sh#8) abrogates tumor formation in NOD/SCID mice (Fig 1G and Appendix Fig S3C; 3 mice/group are shown as an example), suggesting that CEP55 is essential for tumor formation.
