Proliferation of Human Primary Myoblasts Is Associated with Altered Energy Metabolism in Dependence on Ageing In Vivo and In Vitro

Figure 4

Influence of ageing on activity of pyruvate kinase (PK) normalized for complex I dependent respiration (PK/complex I) in myoblasts of passage 2 (P2) and passage 6 (P6) of young (a) and older (b) subjects. (c-d) Influence of ageing on ratio of activity of PK to citrate synthase (CS) of P2 and P6 of young and older subjects. Data are mean ± SEM. compared to passage 2. compared to young subjects.
