Comparison of the lncRNAs between stage IV melanoma patients and healthy subjects in CD4+, CD8+, and CD14+ PBCs, including (1) The density distribution of expressed lncRNAs in stage IV melanoma patients (A) and healthy donors (B) of CD4+, CD8+, and CD14+ PBCs; (2) The number of expressed lncRNAs and their overlaps across CD4+, CD8+, and CD14+ PBCs in stage IV melanoma patients (C) and healthy donors (D); and (3) the differentially expressed lncRNAs by pairwise comparison between CD4+, CD8+, and CD14+ PBCs in stage IV melanoma patients (E) and healthy donors (F).
