Analysis of genomics data from The TCGA project, freely available from web-portal UALCAN [83], revealed significantly different gene expression pattern of AQP5 in normal (median 7.366 transcripts per million (TPM) (0–44.252 TPM)) vs. different subclasses of breast cancer (luminal–0.34 TPM (0–5.848 TPM), HER2-positive-1.79 TPM (0–105.814 TPM), TNBC-8.469 TPM (0–169.313 TPM); Figure 4). Here, ERBB2 is linked to breast carcinoma.
