Estudio de los efectos de un microambiente hipóxico en queratinocitos humanos in vitro y su correlato con alteraciones del microambiente en la patología de liquen plano oral

Abstract

La hipoxia es un factor fundamental en el proceso de génesis tumoral, así como en patologías precursoras de cáncer, como es el Liquen Plano Oral (LPO). Objetivo: Determinar si es posible establecer una correlación entre las alteraciones que sufren queratinocitos normales en un microambiente hipóxico in vitro y alteraciones que aparecen en los queratinocitos en el epitelio de la mucosa oral en el contexto de la patología LPO. Métodos: Se estudiaron los cambios morfológicos mediante microscopía de contraste de fases, y la detección de marcadores asociados a hipoxia de queratinocitos humanos (HaCaT), como modelo celular oral, en un microambiente hipóxico generado por la variante del método “Hipoxia inducida por cubreobjetos”. Resultados: Mediante microscopía confocal se observó la presencia de los marcadores de hipoxia GLUT-1 y aductos de pimonidazol (Hipoxyprobe) en los cultivos celulares de HaCaT expuestos a un microambiente hipóxico. Además, se observó la presencia del marcador GLUT-1 mediante inmunohistoquímica en tejido epitelial humano derivado de biopsias de la patología LPO. Conclusiones: Se estableció una correlación entre las alteraciones detectadas en queratinocitos humanos inducidos a un microambiente hipóxico in vitro y las alteraciones detectadas in vivo en tejido epitelial de la mucosa oral.
