Impact of SOD1 knockout on hepatic GPX1 activity (A), protein amount (B) and co-immunopreciptation of hepatic GPX1 and SOD1 (C). A. Hepatic GPX1 activity was expressed as mean ± SE (n = 5). B. Western blot analysis of hepatic GPX1 protein (10 μg protein/lane). The image is a representative of three independent experiments. C. Co-immunoprecipation of GPX1 and SOD1 in liver homogenates. After 100 μg of total liver homogenate protein was incubated with 1 μg anti-GPX1 or anti-SOD1 antibody overnight at 4°C. The precipitates were loaded to SDS-PAGE (12% gel) and transferred to membranes that were blotted against the designated antibodies. WT liver homogenate was used as the positive control for Western blot. The image is a representative of three independent experiments.
