Exportin 1 (XPO1), also referred to as chromosomal maintenance region 1 (CRM1), is a key nuclear transport receptor involved in the export of more than 200 known cargo proteins, including tumor suppressors, anti-inflammatory factors, and growth-regulating proteins (Hutten and Kehlenbach, 2007; Xu et al., 2010; Xu et al., 2012). Here, XPO1 is linked to neoplasm.
