However, research on midkine\u2010psoriasis relationship remains limited. The objective of this study was to detect midkine expression in psoriasis and investigate its potential role in the disease. Midkine expression was measured using immunohistochemistry and ELISA. Effects of midkine on HaCaT cell proliferation, VEGF\u2010A production and signalling pathways were assessed using CCK8, RT\u2010PCR and WB. Scratch and in vitro tube formation tests were used to evaluate the effects of HaCaT\u2010cell\u2010activated midkine on the migration and tube formation of human dermal microvascular endothelial cells. Murine psoriasiform models were injected with midkine recombinant protein and midkine monoclonal antibody to investigate skin lesions, tissue sections and dermal microvessel density. Levels of midkine significantly increased in both lesions and serum of patients with psoriasis. Serum expression of midkine decreased after treatment and a positive correlation was found between midkine and disease severity. Midkine promoted HaCaT cell proliferation and VEGF\u2010A production. The Notch2\/HES1\/JAK2\u2010STAT5A pathway expression increased after midkine treatment of HaCaT cells. The supernatant of HaCaT cells treated with midkine promoted HMEC\u20101 migration and angiogenesis in vitro. Recombinant midkine protein exacerbated psoriasiform lesions with increased expressions of VEGF\u2010A and microvessel density, while midkine monoclonal antibody alleviated psoriasis lesions. Midkine may have a significant impact on psoriasis angiogenesis by regulating VEGF\u2010A expression through the Notch2\/HES1\/JAK2\u2010STAT5A pathway, highlighting a potential therapeutic target for psoriasis treatment.<\/jats:p>","DOI":"10.1111\/exd.14836","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T07:59:49Z","timestamp":1684828789000},"page":"1383-1393","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Overexpression
