Transcriptomic Profiling of Peripheral Edge of Lesions to  Elucidate the Pathogenesis of Psoriasis Vulgaris
To identify the gene expression in the peripheral edge of the lesional (PE) skin of psoriasis vulgaris. Methods: Full-thickness skin biopsies of PE skin and uninvolved skin were taken from psoriasis patients. Transcriptomic profiling was constructed by high-throughput next-generation sequencing (NGS) technology. Result: A total of 1,202 DEGs were identified. Of these, 653 (54%) were upregulated and 549 (46%) were downregulated. These DEGs might play a pivotal role in psoriasis pathogenesis. This study accelerates psoriasis-associated gene discovery in the whole picture of PE skin. Overall design: PE skin and uninvolved (UN) skin biopsies were taken patients with moderate to severe psoriasis vulgaris. RNA-seq was performed using Next-Generation sequencing.  Alterations of mRNA in PE skin compared to those in UN skin were identified as differentially expressed genes (DEGs).
