In previous studies, several biomarkers as well as pathways have been reported to be correlated with the development of psoriasis, such as apoptosis, cell cycle, angiogenesis, inflammatory response, T cell immune response, VEGF, MAPK, WNT, JAK/STAT, NF-kappa B, and B cell response [7, 31]. This evidence concerns the gene SOAT1 and psoriasis.
