We therefore evaluated HBEGF and DPH2 expression in a series of gene expression datasets: (i) 151 CRC cancer cell lines21, (ii) 515 CRC PDX (manuscript in preparation), and (iii) expression data for colorectal, glioblastoma, head and neck and pancreatic cancer obtained from The Cancer Genome Atlas via the CBioPortal22. Here, DPH2 is linked to glioblastoma.
