(A and B) Cell cycle analysis of HT-29 cell cycle distribution after treatment with NC-19 (0, 2, 4, 8 µM) for 24 hours. (C and D) Western blot and bar graph analysis of CDK2 and Cyclin E protein expression in HT-29 cells after treatment with NC-19 (0, 5, 10, 20 µM) for 24 hours. (E) Cell viability of HT-29 cells pretreated with NAC (2 mM) for 8 hours, followed by incubation with or without 2 µM NC-19 for 72 hours. (F) Detection of ROS generation by DCFH-DA in HT-29 cells after treatment with NC-19 (0, 1, 2, 5, 10 µM) for 24 hours.

Figure Lengend Snippet: Figure 2. In vitro cytotoxicity of Oba01 in MSS and MSI-H CRC cell lines (A and B) DR5 expression in CRC cell lines assessed by western blotting (A) and immunofluorescence (B). Scale bars, 20 μm. (C) Cell viability after treatment with Oba01, zaptuzumab, MMAE, irinotecan, or oxaliplatin, measured by CellTiter-Glo Assay. (D–H) Cell survival upon treatment analyzed by cell confluency using the Incucyte S3 system. (I) Proliferation of Oba01-treated cells detected by EdU assay with confocal microscope. (J and K) Apoptosis of Oba01-treated cells assessed by the Annexin V-FITC and PI Apoptosis Kit. Scale bars, 20 μm. Data represent mean ± SEM of ≥3 experiments. p values from one-way ANOVA. ns, non-significant; *p < 0.05; **p < 0.01; ***p < 0.001.

Article Snippet: Cell apoptosis and cell cycle assay Cells were seeded at the density of 2 × 10 5 cells/well and exposed to Oba01 and/or Abem at the different concentrations for 48 h. Apoptosis was assessed using the Annexin V-FITC and PI Apoptosis Kit (Beyotime Biotechnology, Shanghai, China) and cell cycle status was analyzed by staining with the cell cycle assay kit (Beyotime Biotechnology, Shanghai, China).
