When compared to other types of skin cancer such as basal cell carcinoma or squamous cell carcinoma, BAMBI showed selective overexpression in melanoma and strong co-expression (0.815) with the established melanoma gene EDNRB, but also with HEY1 (0.759), a gene important for vascular development (Figure 4). This evidence concerns the gene HEY1 and squamous cell carcinoma.
