摘要

Psoriasis is a chronic inflammatory skin disorder;its genetic background has been widely studied in recent decades.Recognition of novel factors contributing to the pathogenesis of this disorder was facilitated by potent molecular biology tools developed during the 1990s.Large-scale gene expression studies,including differential display and microarray,have been used in experimental dermatology to a great extent;moreover,skin was one of the first organs analyzed using these methods.We performed our first comprehensive gene expression analysis in 2000.With the help of differential display and microarray,we have discovered several novel factors contributing to the inherited susceptibility for psoriasis,including the EDA+fibronectin splice variant and PRINS.The long non-coding PRINS RNA is expressed at higher levels in non-involved skin compared to healthy and involved psoriatic epidermis and might be a factor contributing cellular stress responses and,specifically,to the development of psoriatic symptoms.This review summarizes the most important results of our large-scale gene expression studies.
