Abstract: Version 1 (v1) 2019-10-10 doi:10.26124/mitofit:ea19.MitoEAGLE.0001


Permeabilized muscle fibers (pfi) are widely used to assess mitochondrial (mt) respiratory function in skeletal muscle of various models in different physiological and pathological conditions. Facing the numerous data available for mt-respiration from the literature, it remains challenging to determine what the right values are for a specific respiratory protocol. Moreover, mt-respiration values are highly dependent on pfi preparation, which required good technical skills.

In the frame of COST Action MITOEAGLE, one of the objectives of WG2 is the generation of reference values for mitochondrial respirometry in permeabilized skeletal muscle sample preparations. The idea is that new researchers in the field follow a reference protocol and check if their values are in an acceptable range. This approach could serve to test researchers’ technical skills and therefore determine if they are proficient enough to perform their own experiments with confidence. - Extended abstract

Figure 1. Substrate-uncoupler-inhibitor titration protocol (SUIT-008 O2 pfi D014). Sequential titrations and respiratory states. 1PM: NADH-pathway (N-pathway) :in the presence of 5 mM pyruvate and 2 mM malate in the N-LEAK state. 2D: saturating ADP (N-OXPHOS state). 2c: 10 μM cytochrome c for evaluating the integrity :of the outer mitochondrial membrane. 3G: 10 mM glutamate as an additional NADH-linked substrate (N-OXPHOS state). 4S: 10 mM succinate (NS-OXPHOS capacity). :5U: uncoupler titrations to evaluate the electron transfer- (ET-) capacity (NS-ET capacity). 6Rot: inhibition of CI by rotenone (S-ET capacity). 7Ama: :inhibition of CIII by antimycin A (residual oxygen consumption, Rox). Oxygen concentration range in the experiment was maintained between 400-250 µM O2.

Figure 2. NS-OXPHOS capacity of permeabilized soleus muscle fibers. NS-OXPHOS capacity was measured in permeabilized soleus muscle fibers from male C57BL/6J mice by :16 research groups. Median with interquartile range show results from individual group with muscle fibers obtained from at least four soleus muscles.
