Respiratory stimulation by simultaneous action of the F-pathway, N-pathway, and S-pathway, with convergent electron flow in the FNS-pathway for reconstitution of TCA cycle function and additive or inhibitory effect of F.
Strengths and limitations
- + The protocol provides information on FAO capacity in the absence of other, potentially interfering pathways, both in the LEAK state and in OXPHOS.
- + FNS OXPHOS capacity comprises the most important pathways in many cell types and thus provides a physiologically relevant estimate of maximum mitochondrial respiratory capacity.
- + FNS ET capacity is a good estimate of overal ET capacity in may cell types.
- + The presence of PMG and S establishes fully operative TCA cycle activity.
- + Application of the cytochrome c test early in the protocol ensures comparability of all states in case of any effect of c.
- + Reasonable duration of the experiment.
- - F OXPHOS capacity may be underestimated. In human heart muscle addition of Oct to palmitoylcarnitine (Pal) + malate increased OXPHOS by 26% (Lemuieux et al 2011).
- - SRot(E) may be underestimated if S is not saturating.
- - CIV activity is not measured, to save experimental time.
