NCS1 and neoplasm: Indeed, studies in neuronal cells reported that NCS‐1 binds to different Ca2+ regulators, which are important for the fine‐tuning of Ca2+ signals regulating specific processes such as neurite elongation and branching (Hui et al., 2007; Hui et al., 2006; Iketani et al., 2009).There have been no studies assessing the effect of NCS‐1 silencing on Ca2+ signaling in MDA‐MB‐231 cells despite two consecutive studies demonstrating a role for NCS‐1 in promoting tumor cell migration and aggressiveness in the same cell line (Apasu et al., 2019; Moore et al., 2017).
