To confirm whether HMGA1P7 works as miRNA sponge for the regulation of H19 and IGF2 expression levels also in human cancer, we evaluated the expression of H19, IGF2 and HMGA1P7 in a panel of breast carcinoma samples by qRT-PCR, since H19 and IGF2 have been reported to be overexpressed in this type of tumor36, 37. The gene discussed is HMGA1P7; the disease is breast carcinoma.
