Resumo

O objetivo deste trabalho foi determinar a expressão de vários biomarcadores moleculares no líquen plano oral para ajudar a compreender seu comportamento biológico. Materiais e métodos: Foi realizado um estudo imunohistoquímico em 40 casos de líquen plano oral contra BAX, BCL-2, CD-138, Histona 3, Ki-67, MCM3 e p53, na área de Patologia Molecular Estomatológica da Faculdade de Odontologia , UDELAR, Uruguai. Resultados: Observou-se aumento da expressão de BAX em contraste com BCL-2, sugerindo um comportamento proapoptótico, apoiado por sua vez pela ausência da expressão de p53. A expressão de marcadores de proliferação celular foi observada em todo o tecido da lesão, sugerindo alterações na proliferação. CD-138 foi expressado de maneira intensa e uniforme, determinando uma baixa alteração das junções intercelulares para esses casos. Conclusões: A alteração na expressão das proteínas estudadas sugere um distúrbio nos mecanismos proliferativos e apoptóticos, os quais estão associados a um comportamento patológico da mucosa oral.
