Mitophagy Assay using mito-QC Reporter
Cited 19 times
Experiments were conducted in either SH-SY5Y or ARPE-19 cells following American Type Culture collection (ATCC) guidance. In brief, cells were cultured in 1:1 DMEM:F-12 media (Thermo Scientific; #12634010) supplemented with 10 % (v/v) FBS (Sigma; #F7524), 2 mM l-glutamine (Thermo Scientific; #25030-024), 100 U/ml penicillin and 0.1 mg/ml streptomycin (Thermo Scientific; #15140-122) and incubated at 37 °C with 5 % CO2 in a water-saturated incubator. The mito-QC reporter was retrovirally transfected as previously described (Allen et al., 2013 (link)). Mitophagy was assessed from pools of cells transfected with the reporter. Iron chelation induced mitophagy with Deferiprone (DFP) (Sigma; #379409) was achieved as previously reported, where cells were treated with 1 mM DFP, dissolved in water before use with a pulse of heat (90 °C), for 24 h. For hypoxia treatment cells were transferred to a Ruskinn INVIVO2 300 workstation (Ruskinn/Baker) at 37 °C in 1 % O2 and 5 % CO2, where were incubated for 42 h. After 36 h incubation in hypoxia, 50 nM of Bafilomycin A1 (Enzo; BML-CM110) was added to inhibit lysosome acidification during the remaining 6 h up to 42 h.
The experiments using the mito-QC reporter to assess mitophagy were processed as previously described (Allen et al., 2013 (link)). In brief, cells containing the mito-QC reporter were washed once with PBS (Thermo Scientific; #14190-094) and fixed with 3.7 % PFA (Sigma; P6148) in 200 mM HEPES (Formedium; HEPES10), pH 7.0 for 10 min at room temperature. Then, samples were washed twice with DMEM media supplemented with 10 mM HEPES pH 7.0 and 0.04 % Sodium Azide (Sigma; S8032), followed by a 10 min incubation. After two washes with PBS, coverslips were incubated with 1 μg/ml Hoechst (Thermo Scientific; #62249) for 30 min, washed three times with PBS, dipped in MilliQ water and mounted onto glass slides with ProLong Diamond Antifade Mountant (Thermo Scientific; #P36961).
The immunostaining of SH-SY5Y mito-QC reporter cells with LAMP1 was performed as follow: cells were washing once with PBS and fixing cells with 3.7 % PFA pH 7.0 for 20 min at room temperature. The cross-linking reaction was quenched as described above. Cells were the permeabilised with 1 % BSA (Roche; #10735108001)/PBS + 0.1 % NP-40 (Merck/Millipore; #492016) for 3 min at room temperature. In contrast to tissue preparations, the permeabilization of cell in vitro can affect the red-only mitolysosome stability. Therefore, the quantification of mitophagy using the mito-QC reporter should be avoided after detergent permeabilization of cells in vitro. Following permeabilization and fixation, coverslips were next washed two times with 1 % BSA/PBS and followed by a 30 min incubation at room temperature. The LAMP1 primary antibody (Santa Cruz; sc-20011) were incubated at 1/300 in 1 % BSA/PBS for 1.5 h at 37 °C. Then, coverslips were washed with 1 % BSA/PBS four times of 10 min each. The secondary anti-mouse Alexa Fluor 647 nm antibody (Thermo Scientific; #A21236) was incubated at 1/1000 in 1 % BSA/PBS for 30 min in the dark at room temperature. Coverslips were washed again four times with 1 % BSA/PBS for 10 min each. Cells were then stained with Hoechst and mounted glass slides as described above.
Images with the mito-QC reporter to quantify mitophagy were acquired using a Nikon Eclipse Ti widefield microscope (Plan Apo Lambda 60x Oil Ph3 DM) with the NIS-Elements software, while the images for the LAMP1 co-localisation experiment were acquired in a Leica SP8 laser scanning confocal microscope (HC PL APO 63x/1.40 oil CS2). All the images were processed with FIJI v1.52n software (ImageJ, NIH). Quantification of mitophagy was performed from three independent experiments counting over 50 cells for condition. Images were processed with the mito-QC Counter. For images acquired in the widefield microscope the following parameters were used: Radius for smoothing images = 1, Ratio threshold = 0.6, and Red channel threshold = mean + 0 standard deviation. For images acquired in the Leica SP8 confocal microscope the following parameters were used: Radius for smoothing images = 2, Ratio threshold = 1.5, and Red channel threshold = mean + 0.5 standard deviation.

Autophagic flux was determined by the measure of LC3 turnover by treating cells with bafilomycin A1 (11038, Cayman, MI, USA), which blocks the fusion of autophagosomes with lysosomes inhibiting the late degradation stage of autophagy. Early- and late-passage C2C12 control cells were seeded at a density of 5 × 103 cells/cm2 and treated 24 h later with 0.2 μM bafilomycin A1 during 24 h. After 4- and 7-days differentiation, early- and late-passage Dif4d and Dif7d cells were treated with 0.2 μM bafilomycin A1 during 24 h. LC3 and SQSTM1/p62 were detected by western blot analysis, as described above.
