( A ) Representative images of HUVECs at 0, 12, and 24 hours after treatment with different concentrations of PF429242 (veh, 2.5, 5, 10 μM); ( B ) Healing rate of HUVECs at 0 and 12 hours after treatment with different concentrations of PF429242 (veh, 2.5, 5, 10 μM); ( C ) Healing rate of HUVECs at 0 and 24 hours after treatment with different concentrations of PF429242 (veh, 2.5, 5, 10 μM); ( D ) Representative images of HUVECs at 0, 12, and 24 hours after treatment with different concentrations of SSR 69071 (veh, 0.01, 0.1, 1 μM); ( E ) Healing rate of HUVECs at 0 and 12 hours after treatment with different concentrations of SSR 69071 (0, 0.01, 0.1, 1 μM); ( F ) Healing rate of HUVECs at 0 and 24 hours after treatment with different concentrations of SSR 69071 (0, 0.01, 0.1, 1 μM); ( G ) Representative images of HUVECs treated with 10 μM PF429242 or 1 μM SSR 69071 for 4 hours, detected by LysoTracker Red staining (nuclei counterstained with Hoechst 33,342). ( H ) Representative images of HUVECs treated with 10 μM PF429242 or 1 μM SSR 69071 for 4 hours, captured by a Multi-SIM system, with lysosomes stained by LysoTracker Red and nuclei counterstained with Hoechst 33342. ( I ) Lysosomal area per cell of HUVECs treated with 10 μM PF429242 or 1 μM SSR 69071 for 4 hours. * p < 0.05; ** p < 0.01; *** p < 0.001

Article Snippet: HUVECs seeded in confocal dishes were treated with drugs for 4 h, stained with 50 nM LysoTracker Red DND-99 (ThermoFisher Scientific, USA) at 37 °C for 45 min, then counterstained with Hoechst 33,342 (1:5000, MCE, USA) for 10 min to label nuclei.

Article Title: Screening a library of antibacterial compounds leads to discovery of novel inhibitors for Neisseria gonorrhoeae and Chlamydia trachomatis

doi: 10.1371/journal.pone.0340486

Figure Lengend Snippet: McCoy cells were infected and incubated for 2 hours before being exposed to SPR719 and gloxazone (at 1 μM), and incubated for 48 hours at 37°C with 5% CO 2 . Azithromycin at 1 μM was used as a positive control. The untreated cells (DMSO) served as a negative control. Nuclear DNA was stained with Hoechst 33342 (blue), primary antibodies bound to the MOMPs of Chlamydia were stained with donkey anti-goat IgG conjugated to Alexa 488 (green), and phalloidin conjugated to California red was used to stain F-actin (red).

Article Snippet: Hoechst 33342 (MedChemExpress, Monmouth Junction, NJ, USA), azithromycin (TCI America, Portland, OR, USA), the phalloidin conjugates California red (AAT-Bioquest, Pleasanton, CA, USA) and Eagle’s Minimum Essential Medium (EMEM) (Sigma-Aldrich, St. Louis, MO, USA).
