YAP1 facilitates the pathogenesis of psoriasis via modulating keratinocyte proliferation and inflammation.

ABSTRACT: Psoriasis is an autoinflammatory skin disease characterized by the abnormal activation of epidermal keratinocytes. The Hippo-YAP pathway is an evolutionarily conserved pathway that plays important roles in organ size control and tumorigenesis. Recently, accumulating evidence demonstrated that YAP1, the core downstream component of Hippo-YAP pathway, was up-regulated in psoriasis patients, suggesting its possible role in psoriasis development. However, its precise function and mechanism in psoriasis pathogenesis are still not well-clarified. In the present study, we confirmed the up-regulation of YAP1 in psoriasis keratinocytes by measuring its expression in psoriatic patient skins, psoriatic-like cellular model, and IMQ-induced mouse model. Further functional studies showed that YAP1 promo
