KLF4 and psoriasis: Twelve of the differentially expressed genes overlapped a psoriasis capture bait fragment (Additional file 3, Table S11) and included ERAP1, ERAP2, IFIH1, RNF114, SOCS1 and STAT2. In addition, 12 differentially expressed genes were involved in bait-promoter interactions (Additional file 7, Table S12) and included candidates such as ICAM1, KLF4 and STAT3. However, the vast majority of these differentially expressed genes interacted similarly with the psoriasis-associated baits in both unstimulated and stimulated cells (CHiCAGO score ≥ 5).
