We carry out a protein-protein interaction (PPI) network analysis for tumor biomarkers in basal cell carcinoma to report significant connectivity among nine key proteins (GADD45B, HSPA1B, HSPB1, CD63, CST3, CD74, HLA-DRA, HLA-DPA1, and NPC2), with a total of 16 interactions identified (p-value = 9.14e-07) [40] [41]. Here, HSPB1 is linked to basal cell carcinoma.
