Metabolomic alterations in HUH6 cells treated with 5 μM CQ. Enrichment analysis showing the most abundantly altered metabolite sets (A). Pathway impact analysis demonstrating the importance of altered metabolites for pathway functionality (B). NAD+ concentrations (C) and NAD+/NADH (D) ratio in CQ treated HUH6 cells compared to untreated control cells. Aspartate concentrations (E) in CQ treated cells compared to untreated control cells. Impact of aspartate supplementation on CQ treated or untreated HUH6 cell viability (F). Single metabolites values are given as normalized concentration (μmol/million cells). NAD+/NADH ratio is presented as percentages of normalized total NAD concentrations. Bar plots are presented as relative values of mean ± RSD, (N = 3). ASP; 10 mM aspartate. Metabolite analyses were performed with MetaboAnalyst 4.0. *P < 0.05, **P < 0.01.
