Interaction between OXPHOS and MEK/ERK pathway. (A) Changes of MEK/ERK pathway after the addition of Rotenone (2 μM, the complex I enzyme inhibitor). (B) Changes of complex I enzyme activity after the addition of PD98059 (20 μM, MEK/ERK pathway inhibitor). (C) Changes of cellular ATP production after addition of PD98059 (20 μM, MEK/ERK pathway inhibitor). (* P < 0.05,** P < 0.01,*** P < 0.001).
