Figure Lengend Snippet: Protective efficacy of AVI against cisplatin‐induced cytotoxicity and apoptosis in LO2 cells. (A) Indicates that LO2 cell viability was not affected by AVI intervention at concentrations ranging from 0 to 400 μM over a period of 2 days. (B) Indicates a significant difference in LO2 cell viability following cisplatin treatment with vs. without AVI co‐culture. (C) Illustrates the dose‐response curves of cell viability to cisplatin following different pretreatment durations (0, 6, 12, and 24 h) with AVI. (D) Shows the apoptosis rate in LO2 cells was quantified using Annexin V‐FITC double staining, (E) shows Cis group has the highest rate of cell apoptosis, while co‐culture with AVI significantly reduced the overall cell apoptosis rate caused by Cis. (F) Shows the apoptosis of cells in each group. Apoptosis was significantly observed in the Cis group, while AVI co‐culture could significantly improve apoptosis. (G) Shows the total amount of ROS produced by cells in each group. The Cis group significantly increased ROS, while AVI co‐culture could significantly reduce the generation of ROS within cells.

Figure Lengend Snippet: Transcriptome sequencing results from four experimental groups of LO2 cells. (A) Principal component analysis (PCA) shows clear separation along PC1 among different treatment groups, indicating value for further analysis. (B) Gene expression distribution (violin plot) demonstrates consistency in expression levels across samples. (C) Heatmap of differentially expressed gene clustering, and (D) Volcano plot of differentially expressed genes, both reveal significant differential gene expression between the Cis group and the AVI+Cis group. (E) Gene Ontology (GO) enrichment analysis shows that the gene set is significantly enriched in the three categories: biological process, molecular function, and cellular component. (F) Based on KEGG pathway enrichment analysis results, the gene set primarily covers key physiological and pathological processes such as immune defense, apoptosis, and signal transduction. (G) Results of Gene Set Enrichment Analysis (GSEA) show that gene sets involved in oxidative stress, inflammatory response, and programmed cell death are significantly negatively enriched in AVI+Cis group.
