Considering that normal breast epithelial MCF10A cells is well-established cell model for exploring the TGFβ-induced EMT process and cancer progression, MCF10A cells were treated with or without TGFβ and then subjected to bioinformatics analysis of their transcriptome profiles to identify TGFβ-regulated circRNAs (GEO accession number: GSE165576). Here, TGFB1 is linked to cancer.
