Time course of changes in cellular respiration in wildtype (parent #6, C-WT #6–8) and VWA8 null cells (KO #6–10, KO #6–13) in response to palmitate fuel. After Day 0 (undifferentiated cells), the cell culture serum concentration was reduced to 0.2% and additional measurements were made at 3, 5, and 7 days of differentiation. Oligo (oligomycin); FCCP (carbonylcyanide p-trifluoromethoxyphenylhydrazine); Rot (Rotenone); AA, Antimycin A.
