The Integrative Genomics Viewer (IGV) snapshot of the MYC 3’-UTR region showed that treatment with VGN50 down-regulated active MYC transcription (i.e., nascent transcripts) in BC-1, while pre-existing MYC mRNA species (i.e., non T->C) showed little changes (Fig. 4e). This evidence concerns the gene MYC and breast cancer.
