P

soriasis is a chronic, relapsing inflammatory skin disease,

characterized by erythematous plaques covered by silvery

scales. While the pathogenesis of psoriasis is still unclear, most

findings indicated that intensifying T helper 1(Th1) and Th17

are required for the development of psoriasis. Cucurbitacin

D is chemically classified as steroid with anticancer activity

on endometrial and ovarian cancer cells. First, we evaluated

the effects of cucurbitacin D on inflammatory mediator and

chemokine production in IL-1α, IL-17A, IL-22, oncostatin M, and

TNF-α (named M5 combination)-stimulated 3D reconstituted

human epidermis. Cucurbitacin D significantly inhibited the

production of IL-1β, IL-20 and GM-CSF. Second, we examined

whether cucurbitacin D influences the expression of proliferation

marker in IL-22 stimulated HaCaT keratinocytes. Cucurbitacin

D significantly suppressed the expression of K16, K17 and Ki67

in IL-22 stimulated HaCaT cells at a concentration of 30µM.

Cucurbitacin D also suppressed M5 induced phosphorylation of

ERK 1/2 in HaCaT cells. These results suggest that cucurbitacin

D may be useful as an anti-inflammatory agent, especially for

psoriasis.
