PTPRC and melanoma: Next, RNA-Seq data from 556 normal skin samples from the GTEx database and 470 melanoma samples from the TCGA were combined, and normal as well as disease cases from the GEO database were also analyzed, we observed that PTPRC was significantly overexpressed in melanoma (Fig. 3f,g), and higher levels of PTPRC expression in melanoma patients tended to have a better prognosis (Fig. 3h,i).
