To determine the in vivo translatability of our data, miR-26b-5p and miR-21-3p expression levels were evaluated by RT-qPCR analysis in 20 FFPE sections of human primary melanoma scored as TAP1 low (n = 10) or TAP1 high (n = 10) based on the immunohistochemical staining of the lesions with anti-TAP1 specific mAb. Here, TAP1 is linked to melanoma.
