REDD1 is required for AMPK dependent PGC1α expression. A) Western blot analysis of AMPK phosphorylation in cultured chondrocytes isolated from Redd1+/+ and Redd1−/− mice. Right panel shows quantification. Values are mean ± SD from three different experiments. B) Western blot analysis of AMPK phosphorylation in cultured chondrocytes isolated from Redd1+/+ and Redd1−/− mice treated with AICAR or vehicle for 24 hours. Right panel shows quantification. Values are mean ± SD from three different experiments. C) qPCR analysis of Pgc1α and Tfam expression in cultured chondrocytes isolated from Redd1+/+ and Redd1−/− mice and treated with AICAR or vehicle for 24 hours. Values are mean ± SD from three different experiments. Right panel shows quantification. Values are mean ± SD from three different experiments. D) Western blot analysis of PGC1α expression in cultured chondrocytes isolated from Redd1+/+ and Redd1−/− mice and treated with AICAR or vehicle for 24 hours. Right panel shows quantification. Values are mean ± SD from three different experiments.
