Gene Expression Suggesting Increase in Intracellular Iron in Psoriatic Lesions.
Significant changes in gene expression of transferrins (TFRC or TFR1) and TFR2, metal regulatory transcription factor 1 (MTF1), specificity protein 1 (SP-1), glutaredoxin 3(GRX3), and ceruloplasmin (CP), involved cellular iron sensing suggest increases in intracellular iron in psoriatic skin. Data from GEO data set GDS4602 comparing healthy patients (n = 64) to Psoriasis Patients with samples from nonlesional healthy skin (n = 58) and psoriatic skin (n = 58). Statistical Analysis: Normal distribution, ANOVA test with bars indicating mean raw values, ± SEM. or nonparametric Kruskall-Wallis test with bars indicating median raw values, ± interquartile range. **** and #### indicating p < 0.0001; *** or ### p < 0.001, * or # p < 0.05 and ns as p > 0.05.
