Figure 4. Cyclin B1/Cdk1-mediated p53 phosphorylation regulated mitochondrial ATP production.

Figure 4

(A) Mitochondrial ATP production was measured in exponentially growing HCT116 p53+/+, HCT116 p53−/−, or stable HCT116 p53−/− transfectants with p53 wild-type, or S315A/S315D mutants (n = 3; mean ± SEM; **P<0.01). (B) Mitochondrial ATP production was measured in the same set of cells additionally transfected with cyclin B1, Cdk1 or scrambled siRNAs for 24 h (n = 3; mean ± SEM; *P<0.05; **P<0.01). (C) Mitochondrial ATP production was measured in the same set of cells transfected with MTS-EGFP and MTS-RFP, or MTS-cyclin B1 and MTS-Cdk1, or MTS-cyclin B1 and MTS-delCdk1 (n = 3; mean ± SEM; **P<0.01).
