IGF2 and breast cancer: To determine if we could corroborate these results in paired (Normal/Malignant) tissue samples obtained from BC patients, we evaluated the methylation status of IGF2 CpG islands (CpG1, CpG3, CpG4, CpG5), DMR1, DMR2, and the newly identified INS-IGF2 DVDMR from twelve paired Normal-Malignant breast tissues (4 AA, 4 CA and 4 VIET).
