Fig. 2. Quercitrin protects UVB-induced inflammation.

Fig. 2

A and B, JB6 cells were pretreated with quercitrin (10, 20, and 40 μM) or acetone for 1 h prior UVB exposure. After 24 h, the cells were collected. Cytoplasmic (A) and nuclear (B) proteins were fractionated and NF-κB expression was examined by immunoblotting. C, Quercitrin administration and UVB irradiation is described in Fig. 1. At 1 day and 7 days, the animals were euthanized and dorsal skin tissues were isolated and fixed in 10% formalin. The mouse skin sections were prepared for Haematoxylin & Eosin (HE) staining. (a), Control without any treatment; (b), Pretreated with 1 mg/mouse of quercitrin, but without UVB exposure; (c) and (e), 1 day and 7 days of post 6-weeks of UVB exposure, respectively, but without pretreatment with quercitrin; (d) and (f), UVB exposure is the same as c and e, but pretreatment with 1 mg/mouse of quercitrin one day before UVB exposure.
