“…As metazoans exhibit a natural propensity to proliferate 41 , the clonal cell divisions are controlled by genetic mechanisms. In the conventional, currently accepted paradigm, called Somatic Mutation Theory (SMT) 42 , development of neoplasm is related with the loss of genetically-conditioned coordination of cell proliferation and differentiation 43 . It is a consequence of evolution, development of clonal multicellularity, and increase of somatic complexity.…”

“…Os melanócitos são células dendríticas originárias de melanoblastos da neuroectoderme que durante a sua embriogênese migraram para diferentes locais como epiderme e derme (8,9). É sabido que todo tumor maligno se utiliza de três principais etapas para se diferenciarem de uma célula normal para uma maligna: iniciação, promoção e progressão (10). A diferenciação de um melanócito normal em maligno não é diferente, e da mesma forma, respeita um longo processo de carcinogênese (10) (Figura 3).…”

“…A segunda etapa do ciclo de carcinogênese requer a atuação de agentes promotores tumorais. A mutação de proto-oncogenes e genes supressores tumorais são considerados facilitadores do desenvolvimento neoplásico (10) . Os proto-oncogenes são genes que codificam proteínas que por sua vez, promovem a progressão do ciclo celular e proliferação.…”
