WebJun 27, 2024 · SAC detects unattached microtubules or tension and causes metaphase arrest to ensure that all chromosomes are attached and aligned properly. Defects in the SAC result in aneuploidy and subsequently, cell death or the formation of cancerous cells (Bharadwaj and Yu 2004; Sun and Kim 2012 ). WebDec 9, 2024 · SAC proteins are not activated during neosis, leading to errors in chromosome segregation during mitosis and aneuploidy [ 55 ]. Unfortunately, it has not been established whether neosis is a mechanism that evades cell death via mitotic catastrophe and whether Raju cells could facilitate tumor self-renewal (Fig. 1) [ 56 ].
