Apart from neuroprotection, INPP4A has been shown to regulate cell proliferation and survival in a number of cell types including fibroblast cells (Chaudhuri et al., 2018; Ivetac et al., 2009; Khanna et al., 2019; Morioka et al., 2016; Vyas et al., 2000), and has been implicated in cancer (Chaudhuri et al., 2018; Erkeland et al., 2004; Huang et al., 2019; Jiang et al., 2015; Lin et al., 2014; Maher et al., 2009; Mäki‐Nevala et al., 2016; Thutkawkorapin et al., 2019; Wang et al., 2018). The gene discussed is INPP4A; the disease is cancer.
