Figure 2. Differential regulation of UGT expression by acute sunburn vs chronic suberythemal UV-B exposure.

Figure 2

(A) Schematic of exposure schedule for acute vs chronic UV-exposure. (B) The indicated predesigned Taqman gene expression assay was used to visualize individual UGT expression by real-time PCR following treatment of primary human melanocytes isolated from a Caucasian individual at 4, 8 and 24 hrs post acute, sunburn, UV-B irradiation (25 mJ/cm2). (C) UGT Taqman assays of Caucasian melanocytes at 4 and 24 hrs post chronic UV-B exposure (10 mJ/cm2 × 5 treatments). All assays are normalized to GAPDH and performed in triplicate. UN=Untreated.
