Resumen
El objetivo del presente trabajo fue determinar la expresión de diversos biomarcadores moleculares en liquen plano oral para ayudar a comprender su conducta biológica. Materiales y métodos: Se realizó un estudio inmunohistoquímico en 40 casos de liquen plano oral contra BAX, BCL-2, CD-138, Histona 3, Ki-67, MCM3 y p53, en el Área de Patología Molecular Estomatológica de la Facultad de Odontología, UDELAR, Uruguay. Resultados: Se observó mayor expresión de BAX en contraposición con BCL-2, sugiriendo un comportamiento proapoptótico, respaldado a su vez por la ausencia de expresión de p53. La expresión de los marcadores de proliferación celular fue en todo el tejido lesional observado, sugiriendo así alteraciones de la proliferación. CD-138 se expresó de manera intensa y uniforme, determinando una baja alteración de las uniones intercelulares para estos casos. Conclusiones: La alteración en la expresión de las proteínas estudiadas sugiere un trastorno en los mecanismos proliferativos y apoptóticos, los cuales se asocian con una conducta patológica de la mucosa oral.
