ETS1 and cancer: Increased expression of ETS‐1 is associated with cancer metastasis (Behrens et al., 2001; Dittmer, 2003; Ghosh et al., 2012; Nakada et al., 1999; Nakayama et al., 1996; Span et al., 2002), and its forced expression leads to a transformed phenotype, as shown by tumor formation in xenograft mice (Topol et al., 1992).
