Résumé

A pale skin and an intense solar exposure are risk factors for skin cancer. however, from an evolutionary point of view, it is less clear which is the factor that drives or has driven the evolution of the pigmentation of the human skin. thus, several hypotheses coexist, like photoprotection against skin cancer, photoprotection of circulating photolabile compounds, vitamin D síntesis, sexual selection, among others, none of them prooved. In this work we aim at identifying those loci of relevance in the pigmentary phenotype by means of two approaches: a) the identification of a signature of adaptive selection in the diversity and divergence profiles of a series of candidate loci and b) the analisis by microarrays of the expression profiles of melanocytic cell lines of different constitutive pigmentation, both irradiated and not irradiated with UV ligth (A*B).
