Assessment of a large panel of breast cancer cell lines using data from the Neve study 48 using the GOBO platform 49 indicated similar patterns of expression to ex vivo tissues with TNBC cases showing the highest FAT1 mRNA levels, followed by HER2 positive lines while ER/PR+ lines recorded the lowest expression (Fig. S5A). The gene discussed is ERBB2; the disease is breast carcinoma.
