To our surprise, Hmga2-deficient tumours formed in the pancreata of KP172CT;Hmga2CK/CK, KPHetCT;Hmga2CK/CK, and KPKOC;Hmga2CK/CK mice with similar rate and morphology and within a comparable time course as in control KP172CT, KPHetCT and KPKOC mice (Fig. 2). This evidence concerns the gene HMGA2 and neoplasm.
