Through the re‐analysis of single‐cell RNA‐Seq (sc‐RNA‐Seq) data derived from 31 melanoma patients,20 we found that KPNA2, DTL, BACE2 and DTYMK are not only expressed by melanoma cells (Figure 7A,B), but also by non‐malignant cells such as endothelial cells, cancer‐associated fibroblasts (CAFs), and immune cells (Figure 7C,D). Here, BACE2 is linked to cancer.
