Dopachrome tautomeraseinduction in melanocyte co -cultures. Melanocytes were either melanocortin MC1 receptor wild type (WT–QF1106 strain), heterozygous for R151C (QF1200 strain) or heterozygous for R160W (QF1100 strain). Co-cultures of melanocytes with keratinocytes were treated with the following compounds: C = Control, N = 20nM NDP-MSH or F = 10uM forskolin, for four days, then total cell extracts were used for western immuno-blotting with dopachrome tautomerase(Santa Cruz) and GAPDH antibodies. This blot is representative of responses seen in three different wild type and variant strains.
