An anti-malarial drug, Artemisinin, decreased the expression of Angiopoietin 2 and VEGFC, but not VEGFA or VEGFB, in a mouse model of rosacea induced by LL37, the proinflammatory form of cathelicidin [25], and showed a beneficial clinical effect in rosacea patients [26]. The gene discussed is VEGFC; the disease is rosacea.
