(A) Metabolomic profiling of PANC-1, PANC-1-Mg, PANC-1-Al-Mg, Huh7, Huh7-Mg, and Huh7-Al-Mg groups using LC-MS identified 1824 metabolites. (B) PCA illustrating clustering among different cell groups. (C) Heatmap showing differential abundances of characteristic metabolites across cell groups. (D) K-means clustering analysis highlighting metabolic differences among the cell groups. (E) Venn diagram displaying common differential metabolites among treatment groups. (F) Volcano plots of differential metabolites following Mg or Al-Mg treatment. (G) KEGG pathway enrichment analysis of differential metabolites. (H) Enrichment distribution of differential metabolites in Huh7 or PANC-1 cells treated with Mg or Al-Mg. (I) Quantitative analysis of intracellular metabolites including L-glutamine, adenine, uridine, cytidine, and guanine by ELISA with Mg or Al-Mg exposure. (J) Western blot analysis of p21, CDK4, and PCNA expression in PANC-1 cells after Mg or Al-Mg exposure. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
