Chafuroside B, an Oolong Tea Polyphenol, Ameliorates UVB-Induced DNA Damage and Generation of Photo-immunosuppression Related Mediators in Human Keratinocytes
Figure 3
Chafuroside B enhanced IL-12 mRNA expression and production in human keratinocytes.
A NHEK were treated with chafuroside B (0.3 and 1 µM). The cells were harvested after 3 h and IL-12 mRNA was quantitated by means of RT-PCR. B NHEK were treated with chafuroside B (0.3 and 1 µM). After 72 h, supernatants were collected and IL-12 was evaluated by means of ELISA. Cha B = Chafuroside B. All data are expressed as the mean ± sd (n = 3 or 4). *P<0.05 compared with the control.
