Figure Lengend Snippet: Effects of inhibiting and activating AMPK signaling on lipid components in LMH cells. (A) Z score plot for Group C vs. Group H vs. Group H+MA vs. Group H+MA+A vs. Group H+MA+C. The Z score plot normalizes differential lipid molecules across different samples by calculating Z score values. The calculation formula is z=(x-μ)/σ, where x represents a specific score, μ denotes the mean, and σ indicates the standard deviation. The horizontal axis displays Z score values, the vertical axis shows differential lipids, and the differently colored points indicate samples from different groups. (B) Heatmap plot for Group C vs. Group H vs. Group H+MA vs. Group H+MA+A vs. Group H+MA+C. The horizontal axis represents different experimental groups, whereas the vertical axis denotes the differentially expressed lipid molecules within each group. The expression level of each lipid is indicated by a color gradient, with darker shades reflecting greater statistical significance. Color blocks at different positions represent the relative expression levels of corresponding lipid molecules at those positions: red indicates high expression of the substance in that group, while blue indicates low expression. (C) KEGG pathway annotation classification diagram for Group C vs. Group H vs. Group H+MA vs. Group H+MA+A vs. Group H+MA+C. The horizontal axis represents the enrichment ratio for each pathway, while the vertical axis displays the names of the metabolic pathways. Colors indicate the magnitude of p values, with redder hues corresponding to smaller p values, signifying more significant enrichment.

Article Snippet: To determine whether AdipoRon alleviates mixed fatty acid-induced lipotoxic injury in LMH cells via AMPK signaling, the cells were grouped and treated as follows: cells in the control group (Group C) were cultured in normal serum-free medium; cells in the model group (Group H) were cultured in serum-free medium supplemented with mixed fatty acids (0.30 mM OA + 0.15 mM PA); cells in the fatty acid + medium AdipoRon group (Group H+MA) were cultured in serum-free medium supplemented with mixed fatty acids (0.30 mM OA + 0.15 mM PA) and 40 μM AdipoRon; cells in the AMPK antagonist Compound C group (Group H+MA+C) were cultured in serum-free medium supplemented with mixed fatty acids (0.30 mM OA + 0.15 mM PA), 40 μM AdipoRon, and 10 μM Compound C (Cat# HY-13418A, MedChemExpress); and cells in the AMPK agonist Acadesine (AICAR) group (Group H+MA+A) were cultured in serum-free medium supplemented with mixed fatty acids (0.30 mM OA + 0.15 mM PA), 40 μM AdipoRon, and 0.5 mM AICAR (Cat# HY-13417, MedChemExpress).
