doi: 10.1371/journal.pone.0334618

Figure Lengend Snippet: Transwell assay was used for assessment of anti-invasive potential of the Ph-triazole against SW1990 and PANC-1 cells in vitro after incubation with 0.5, 8, and 32 µM concentrations. Quantification of the invaded cells was performed, and pictures were taken at x100 magnification. ** p < 0.01 and * p < 0.05 relative to control cells.

Article Snippet: The pancreatic carcinoma cell lines SW1990 and PANC-1 as well as the normal pancreatic duct epithelial cell line (HPDE6-C7) were provided by the American Type Culture Collection (ATCC).

Article Title: Ciprofloxacin enhances RSL3-induced ferroptosis by promoting mitochondrial Zn 2+ accumulation via the STING1–CAV2 pathway

doi: 10.1016/j.jbc.2025.110653

Figure Lengend Snippet: Antibiotics screening identifies ciprofloxacin (CFX) synergies with RSL3 to inhibit PDAC cell viability. A, PANC1 cells were treated with 50 antibiotics (20, 30, 40, and 50 μg/ml) in combination with RSL3 (0.25, 0.5, 0.75, and 1 μM) at four concentration gradients for 24 h. Cell viability was measured by CCK-8 assay. Synergy score for drug combinations quantified by zero interaction potency (ZIP) model in SynergyFinder web application (version 3.0). Synergy score less than −10 means antagonistic, from −10 to 10 means additive, and larger than 10 means synergistic. B, heatmap representing ZIP synergy score of the 50 antibiotics in combination with RSL3 for treatment of PANC1 cells. Data were representative of independent experiments. C, cell viability curves of PANC1, SW1990, HeLa, and OVCAR-3 cells treated with different concentrations of CFX in combination with RSL3 for 24 h. D, ZIP synergy scores of CFX in combination with RSL3 in PANC1, SW1990, HeLa, and OVCAR-3 cells. E, clone formation image of PANC1, SW1990, and HeLa cells untreated (Ctrl group) or treated with RSL3 (0.5 μM) in the presence or absence of CFX (50 μg/ml) for 24 h, and cell clone formation was detected after 2 weeks. Data are presented as the mean ± SD from at least three independent experiments. p Values were calculated using two-way ANOVA ( C ) or one-way ANOVA ( E ). CCK-8, Cell Counting Kit-8; PDAC, pancreatic ductal adenocarcinoma.

Article Snippet: Human tumor cell lines SW1990 (CRL-2172), PANC1 (CRL-1469), HeLa (CCL-2), and OVCAR-3 (HTB-161) were procured from the American Type Culture Collection and examined every 3 months to ensure they remained free of mycoplasma contamination.
