STAT1 is commonly considered as a tumor suppressor (Meissl et al., 2015) as observed in murine sarcomas (Shankaran et al., 2001) and several mouse breast cancer models (Chan et al., 2012; Klover et al., 2010; Raven et al., 2011; Schneckenleithner et al., 2011). The gene discussed is STAT1; the disease is neoplasm.
