Briefly, just after hyperoxia exposure, MLE12 cells have been fixed with four PAF for 15 min at room temperature and then permeabilized for the duration of two min on ice with 0.1 Triton-X-100 in 0.1 sodium citrate freshly prepared. Cells have been incubated with Tunel reaction buffer for 1 h at 37 The nuclei have been stained with four,6-Diamidino-2phenylindole (DAPI, 1:200; Roche Diagnostic, Basel, Switzerland). These slides have been then mounted with fluosave as described previously. Pictures have been acquired by confocal microscopy (LSM510 Meta, Zeiss) and quantified using Metamorph evaluation software program (50 cells, three independent experiments). Detection of reactive oxygen species Right after hyperoxia exposure, MLE12 had been stained with 10 of dihydroethidium (DHE, Invitrogen, Basel, Switzerland) diluted in PBS. Photos were captured just after 30 min with inverted microscope (Nipkow) and analyzed with Metafluor imaging application (Molecular Devices). Values were obtained by measuring fluorescence intensity on MLE12 cells (50 cells) from three independent experiments [7].A-966492 DNA oxidation staining After hyperoxia exposure, MLE12 cells had been fixed with 4 PAF for 1 h at room temperature and then permeabilized in the course of 2 min on ice with 0.CCCP 1 Triton-100 in 0.PMID:34337881 1 sodium citrate freshly prepared. Cells have been incubated with 8hydroxy-2′-deoxyguanosine antibody (8-OHdG, 1:30; Oxis, Beverly Hills, US) for 1 h at 37 As secondary antibody, a goat anti-rabbit Texas Red conjugated (dilution 1:250; Molecular Probe, Lucerne, Switzerland) was used. The nuclei were stained with (DAPI) (1:200; Roche Diagnostic, Basel, Switzerland). These slides have been then mounted with fluosave (VWR, Nyon, Switzerland) as described previously. Images have been acquired by confocal microscopy (LSM510 Meta, Zeiss, Feldbach, Switzerland) and quantified utilizing Metamorph analysis software program (50 cells, three independent experiments). Cell development Cells have been seeded in 96-well plates and incubated for unique instances. Cell growth was 540 stopped by addition of 50 l of trichloroacetic acid (50 v/v) and protein content of every well was determined by staining with sulforhodamine B [22]. Absorbance was determined at 490 nm. The connection amongst cell number (protein content per well) and absorbance is linear from 0 to 5.106 cells. Western blot evaluation Right after hyperoxia exposure, cell proteins were extracted as previ.
