However, analysis of The Cancer Genome Atlas (TCGA) RNA-Seq datasets on human primary tongue SCCs showed that ZEB1 mRNA levels do not statistically correlate with EPB41L5 mRNA levels (Fig. 3a), whereas a tight correlation between ZEB1 mRNA levels and EPB41L5 mRNA levels was observed in our TCGA RNA-Seq analysis on human primary breast cancers [18]. Here, EPB41L5 is linked to breast carcinoma.
