Figure 4. Identification and characterization of energy metabolism-active populations. (A) AUC scores for specific energy metabolism marker genes; (B) UMAP color-coded plot based on cell activity scores, where brighter colors indicate higher response scores and activity levels to the gene set; (C) Histogram showing the distribution of active and inactive energy metabolism cell populations in different cell groups; (D) Bubble plot of KEGG enrichment results for differentially expressed genes; (E) Bubble plot of GOBP enrichment results for differentially expressed genes.
