Strengths and limitations
- + This protocol allows to evaluate the function of the TCA cycle without the involvement of the complex II (S-pathway). Would be useful to understand the contribution and the activity of the dehydrogenases.
- + Mitochondrial external membrane integrity can be measured with the addition of cytochrome c. 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.
- + Complex IV activity can be measured.
- + GM and PM yield typically identical fluxes in human skeletal muscle fibres. However, PM is the superior alternative to GM: the fraction of the N-pathway is lower and of the S-pathway is higher with GM compared to PM (GMP is inhibited by the CII inhibitor malonic acid to a larger extent than PMP). PM, therefore, yields a more sensitive assay for the diagnosis of injuries in the N-pathway, since an impairment of N-pathway capacity can be compensated partially by activation of the S-pathway. This is an advantage compared to SUIT-011 for diagnosis of N-capacity.
- - Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
