Expresión y relevancia funcional de NADPH oxidasa 5 en células estelares hepáticas humanas

Abstract

Teniendo en cuenta que la expresión de Nox5 está aumentada en sangre periférica de pacientes cirróticos [223] y en muestras de pacientes con hepatocarcinoma [224], que las NADPH oxidasas están alteradas en la fibrosis hepática y el papel clave de las HSC en esta enfermedad, la hipótesis que nos planteamos fue la siguiente: Nox5 participa en la generación de ROS y en el desarrollo de la fibrosis en células estelares hepáticas humanas activadas. A partir de la hipótesis el objetivo general fue la caracterización y el estudio funcional de la Nox5 en células estelares hepáticas. Para ello, los objetivos específicos planteados fueron: 1. Determinar qué variantes las NADPH oxidasas (Nox) se expresan en la línea humana de células estelares hepáticas (HSC), LX-2. 2. Caracterizar qué isoformas de Nox5 se expresan en LX-2 y validarlos por silenciamiento a nivel de mRNA y proteico. 3. Medir la producción de ROS y proliferación tras sobreexpresar Nox5 en HSC humanas. 4. Determinar si las citoquinas profibrogénicas afectan a la expresión de Nox5 en LX-2. 5. Estudiar la posible participación de Nox5 en la síntesis de colágeno de tipo I en HSC humanas.
