Figure Lengend Snippet: (A) At a concentration of 5 nM, TN significantly enhanced the apoptosis induced by 1.56 µM OXA in HCT116 and LoVo cells, as demonstrated through Annexin V/PI staining. Furthermore, HCT116 and LoVo cells that were pre-incubated with or without NAC (5 mM) for 2 h prior to co-administration of OXA and TN exhibited alterations in apoptotic activity. (B)Quantitative analysis of A. (C)The impact of NAC pre-treatment on the combination of TN with OXA treatment on colony formation. (D)Western Blot was used to assess mitochondrial apoptosis-related proteins. (E)The cells were treated with 1.56 μM OXA and/or 5 nM TN, followed by immunoblotting to assess Cleaved Caspase3 and Cleaved PARP protein.This treatment effect was notably mitigated by NAC pre-treatment. (F)HCT116 and LoVo cells were pre-incubated with different concentrations (μM) of Caspase inhibitor Z-VAD-FMK for 2 h before co-administration of TN and OXA drugs. CCK8 method was used to detect cell activity, which was repeated at least 3 times. The control group was given the same amount of DMSO. The results provided originate from three separate trials and are depicted as mean ± standard deviation. Significance levels were indicated as * P < 0.05,** P < 0.01, *** P < 0.001, and **** P < 0.0001.
