In psoriasis uninvolved skin (Table 2), positive correlations were found between the expression levels of CREB1 and LEF1 (r = 0.66, p < 0.05), USF1 and PNOC (r = 0.81, p < 0.05), MITF and ATRN (r = 0.58, p < 0.05), MITF and NURR1 (r = 0.56, p < 0.05) and MITF and MAPK14 (r = 0.75, p < 0.01). The gene discussed is MAPK14; the disease is psoriasis.
