HMGA1 and cancer: The expression levels of HMGA1 in our system are in agreement with previous studies, which describe HMGA1 as highly abundant during embryogenesis, especially in embryonic stem cells; with intermediate expression levels in undifferentiated cancers and at low or at not detectable levels in adult differentiated cells and fibroblasts (Fusco and Fedele, 2007; Hillion et al., 2008, 2009; Resar, 2010; Chou et al., 2011; Schuldenfrei et al., 2011; Shah et al., 2012; Williams et al., 2015).
