Protein extracts were isolated from the hearts of 15-day-olds extracted with RIPA lysis buffer (50 mM Tris-HCl at pH 7.4, 150 mM NaCl, 1% Triton X-100, 1% sodium deoxycholate, 0.1% SDS, 1 mM dithiothreitol (DTT), 5 mM EDTA, and Halt Protease and Phosphatase Inhibitor Cocktail from Thermo Fisher Scientific), and the protein concentration was measured using DC Protein Assay kits (Bio-Rad).
Equal quantities of proteins were resolved by SDS-PAGE gels and blotted onto polyvinylidene difluoride membranes (Millipore). Then, the membranes were blocked with 2% bovine serum albumin (BSA) before incubation with the primary and secondary antibodies. The immunoblots were visualized by using Luminata -Immobilon Crescendo Western HRP Substrate (Millipore) on a ChemiDoc MP station (Bio-Rad). Image analysis was performed using Image Lab software version 5.2 (Bio-Rad). The antibodies used for the western blots were as follows: anti-Srsf3 (Abcam, ab198291) anti-Gapdh (Cell Signaling, 2118), anti-Tim50 (Santa-Cruz, sc-393678), anti-Tom20 (Abcam, ab186735), Total OXPHOS antibodies (Abcam, ab110413), and anti-Uqcrc1 (ThermoScientific, PA5-21394).

Western blot analysis was conducted as previously described (Timper et al., 2017 (link)). In brief, membranes were blocked with 10% WB-blocking reagent (Roche, Switzerland) in Tris-buffered saline containing 0.1% Tween-20 (TBS-T), and incubated with primary antibodies, made up in TBS-T (0.1% Tween-20) and 5% Western Blotting-Reagent, at 4°C overnight. The following primary antibodies and dilutions were used: anti-GLP-1R (1:1000, #NBP1-97308, Novus Biologicals), anti-Akt (#4686, Cell Signaling), anti-p-Akt(S473) (#4060, Cell Signaling), anti-NDUFA9 (1:1000, #459100, Invitrogen), anti-NDUFB8 (1:1000, #459210, Invitrogen), anti-Complex II 70 kDa Fp Subunit (1:1000, #459200, Invitrogen), anti-UQCRC1 (1:1000, #459140, Invitrogen), anti-Complex IV (1:1000, #459110, Invitrogen), anti-ATP synthase subunit β (1:1000, #21351, Invitrogen), anti-p-Ser-226-GLUT-1 (#ABN991, Merck Millipore), anti-GLUT-1 (#07-1401, Merck Millipore), anti-FGF21 (#AF3057, R&D Systems) and, as loading control: anti-calnexin (1:4000, #208880, Merck Milipore). Quantification of chemiluminescent signals was performed with the ImageJ (Fiji)-software package (Schneider et al., 2012 (link)).

Respiratory Complex Assembly Analysis

After electrophoresis, gels were further processed for either western blotting or In Gel Activity IGA assays.
In order to analyze the assembly status of respiratory complexes and supercomplexes, proteins separated by BN were transferred onto PVDF membranes and probed with specific antibodies that recognize the different respiratory complexes (anti-NDUFA9, anti-SDHA, anti-Uqcrc1 and anti-COI for complexes I, II, III, IV respectively, all of them from Invitrogen, and anti-β-F1-ATPase, for complex V, kindly gifted by Dr. J.M. Cuezva). Then, they were incubated with their corresponding secondary antibody, tagged with peroxidase (ThermoFisher Scientific, Waltham, MA, USA). Finally, protein levels were evaluated by immunoblot, using an AmershamTM Imager 600 to document the signal.
Complex I IGA assays were performed after BN-PAGE by incubating the gels at room temperature in the presence of 0.1 M Tris-HCl pH 7.4, 0.14 mM NADH and 1 mg/mL of nitro-blue tetrazolium (NBT) as previously described [80 (link)]. Complex V IGA staining was performed by incubating the gels in 34 mM Tris, 270 mM glycine, 14 mM MgSO4, 0.2% Pb(NO3)2 and 8 mM ATP at pH 7.8, as described before [81 (link)]. After incubation, the gels were photographed with a digital camera using as background a white translucid screen for Complex I and Complex IV and a black screen for Complex V [81 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
