Repeated Suberythemal UVB Preexposure Protects against High-Dose UVB-Induced Expression of Vitamin D Receptor Protein in Human Skin

deficiency may co-exist ina small percentage of nevus cells toenhance melanocyte proliferation anddrive neoplastic transformation. Theabsence of a mutant-specific B-RAFantibody has so far precluded theexecution of such an analysis. It is wellestablished that activated B-RAF canpromote nevus formation in murine andfish melanoma models (Patton et al.,2005; Goel et al., 2009), and thearrested state of nevi does not appearto require p16
