Among the four bulk RNA-seq datasets, only the PRJEB23709 dataset had pre-ICT biopsies for melanoma patients treated with either anti-PD-1 (41 patients: 19 non-responders vs 22 responders) or the combination of anti-PD-1 and anti-CTLA-4 drugs (32 patients: 8 non-responders vs 24 responders). Here, CTLA4 is linked to melanoma.
