Cuproptosis Facilitates Chronic Skin Inflammation by Regulating the α-Ketoglutarate/H3K4me3/Ferritin Heavy Chain 1 Signaling Pathway-Mediated Ferroptosis.

ABSTRACT: Dysregulated copper homeostasis is implicated in inflammatory skin diseases such as psoriasis and atopic dermatitis (AD), but the role of cuproptosis remains poorly defined. This study aimed to elucidate the role and mechanism of cuproptosis in inflammatory skin diseases. Transcriptome analysis of patient lesions revealed significant alterations in cuproptosis-related genes correlating with disease-specific pathological features. These cuproptosis-related gene expression signatures demonstrated strong clinical relevance to therapeutic efficacy in both psoriasis and AD cohorts. Functional validation using disease models showed that pharmacologically inhibiting cuproptosis with the copper chelator tetrathiomolybdate (TTM), or genetically knocking down the copper importer SLC31A1, effectively
