Radicales libres de oxígeno y superóxido dismutasas: aspectos biológicos y médicos

Abstract

Los radicales libres de oxígeno (RLO) son metabolitos muy reactivos e inestables capaces de alterar moléculas de gran importancia biológica corno proteínas, lípidos y ácidos nucleicos. La acción de los RLO está controlada por enzimas como las superóxido dismutasas (SOD), la catalasa y la glutatión peroxidasa y moléculas como las vitaminas E, C, A, y K, el selenio, la cisteína y otros compuestos. El aumento de los niveles de RLO, causados por un aumento en su producción o por una falla en las moléculas que los controlan, provocan daños celulares y tisulares que pueden generar patologías como ateroesclerosis, artritis, distrofia muscular, fibrosis, daños pulmonares, daños al miocardio por reperfusión post isquemia, alteraciones neurológicas y cáncer. En este artículo también se considera la utilización principalmente de las SODs como agentes terapéuticos en modelos experimentales y humanos. Se trata el tema de la administración de esta enzima corno factor protector de los daños colaterales inducidos por radioterapia y la utilización de las SODs como marcadores de la evolución tumoral
