We then combined microarray and RNA-seq experiments to classify samples from three human cell types (human Fibroblasts (Fib), human Embryonic Stem Cells (hESC) and human induced Pluripotent Stem Cells (hiPSC)) and from four classes of breast cancer (subtype Basal, HER2, Luminal A and Luminal B). This evidence concerns the gene ERBB2 and breast carcinoma.
