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.
