In addition,using the maph (multiplex amplifiable probe hybridization) technique 2 new cnvs(copy number variants) were identified in the gene slc24a5: in exon 1and in 5\u00c2\u00bfpromoter region.Furthermore, we demonstrated that natural selection is favouring alleles 374f ofslc45a2 and 60l of mc1r, associated with the depigmentation process of europeanpopulations, but at the same time, with an increased susceptibility to melanoma.Using cell cultures of melanocytes from light- and dark-skinned individuals wedemonstrated that they behave differently in response to ultraviolet irradiation, both ata proliferative and gene expression levels. In addition, we propose that ribosomalproteins, mdm2 and p53 signaling pathway are involved in the response to ultravioletirradiation in both cell types.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Identification of genes and biological pathways involved in human skin pigmentation variability in an evolutionary framework<\/strong>\u00ab<\/h3>\n<ul>\n<li><strong>T\u00edtulo de la tesis:<\/strong>\u00a0 Identification of genes and biological pathways involved in human skin pigmentation variability in an evolutionary framework <\/li>\n<li><strong>Autor:<\/strong>\u00a0 Saioa Lopez Lopez <\/li>\n<li><strong>Universidad:<\/strong>\u00a0 Pa\u00eds vasco\/euskal herriko unibertsitatea<\/li>\n<li><strong>Fecha de lectura de la tesis:<\/strong>\u00a0 10\/09\/2014<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Direcci\u00f3n y tribunal<\/h3>\n<ul>\n<li><strong>Director de la tesis<\/strong>\n<ul>\n<li>Santos Alonso Alegre<\/li>\n<\/ul>\n<\/li>\n<li><strong>Tribunal<\/strong>\n<ul>\n<li>Presidente del tribunal: rosario Calderon fernandez <\/li>\n<li>Carlos Alberto Flores infante (vocal)<\/li>\n<li>paolo Francalacci &#8212;
