Figure 2. E2F1 suppresses BM PC oxidative metabolism via PDK4/2 expression.
(A–B) qRT-PCR analyses for mRNA expression of representative glycolysis and mitochondrial genes (A) and PDK genes (B) in WT and E2F1−/− BM PCs. The expression levels of individual genes were normalized to the β-actin mRNA and expressed relative to their levels in WT cells. n = 5 per group. (C–D) Western-blotting analyses (C) and quantification (D) of PDK2, PDK4 and phospho-PDH protein levels in BM PCs. n = 4 per group. (E–F) OCR measurements (E) and quantification (F, left panel, at basal condition; right panel, after FCCP injection) in WT and E2F1−/− PCs transduced with control-mCherry lentivirus and in E2F1−/− PCs transduced with PDK4-mCherry lentivirus. n = 5 per group. (G–H) ECAR measurements (G) and quantification (H, left panel, at basal condition; right panel, after Oligomycin treatment) in WT and E2F1−/− PCs transduced with control-mCherry lentivirus and in E2F1−/− PCs transduced with PDK4-mCherry lentivirus. n = 5 per group.
