To test, if that holds true, we used the cBioPortal and explored correlation of MEG3 with miRNAs using data on invasive breast cancer from the Cancer Genome Atlas (TCGA) (Cancer Genome Atlas Network, 2012) we found that of 40 miRNAs that had positive correlation over 0,3 (Person score) with MEG3, 30 were located at the DLK1-DIO3 locus (with other miRNAs from the locus not being in the dataset; Table 1). This evidence concerns the gene DLK1 and invasive breast carcinoma.
