Figure Lengend Snippet: a OXPHOS metabolism, reflected by oxygen consumption rate (OCR) levels were measured in MiaPaCa-2 cells after 24 h treatments. b MiaPaCa-2 cells were treated with ZZW-115 (1.5 µM) and olaparib (25 µM) for 24 h, then, loaded with MitoTracker Deep-Red FM and, after fixation, stained with DAPI. Flow cytometry analysis were carried out using MitoProbe™ TMRM ( c ), MitoSOX™ Red ( d ), CellROX™ Orange Reagent ( e ) or Fluo-4-AM ( f ) for analysis of the mitochondrial membrane potential, mitochondrial superoxide levels, intracellular ROS levels and the cytosolic calcium concentration, respectively, after 24 h of incubation with the drugs. Data represent mean ± SEM. Two-way, Sidak was used, * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.001. g PLA was performed in MiaPaCa-2 cells in the presence or in the absence of ZZW-115 together or not with 5-FU in the presence or absence of olaparib. Mouse anti-PAR and rabbit anti-Mitofusin2 antibodies were used. A representative experiment is shown ( n = 3). ImageJ was used to count the number of green dots. Mean ± SEM of foci/nucleus are included.

Article Snippet: Finally, samples were mounted using the Prolong Gold antifade reagent with DAPI (Thermon Fisher).
