IGF2 and carcinoma: As shown in Fig. 5C, HMGA1P7 was overexpressed in most of the carcinoma samples as well as H19 and IGF2. Moreover, the direct correlation between HMGA1P7 and H19 expression (Spearman r = 0,8656; p < 0,001) and between HMGA1P7 and IGF2 expression (Spearman r = 0,7958; p < 0,001) underlines that these genes are co-regulated (Fig. 5D).
