Figure 1.

Figure 1. FA metabolism is altered in HPV-unrelated HNC and upregulated FA catabolism correlates with response to neoadjuvant SBRT with checkpoint blockade. A, Z-score of genetic expression of selected genes derived from RNA-seq from human samples from Darragh and colleagues (20). Significantly upregulated in responders by those shown with the red asterisk, whereas significantly downregulated shown with the blue asterisk (Mann–Whitley test, P < 0.05). B, Selected genes coded by color: PPARs (orange), peroxisomal acyl-CoA oxidases (light blue), carnitine shuttle enzymes (gray), mitochondrial acyl-CoA dehydrogenases (purple), glycolytic enzymes (green), pyruvate dehydrogenase kinases (red), and lactate dehydrogenases (dark blue). C and D, Overall survival of patients from TCGA H&N cohort split into high or low genetic expression PPARA (C; log2 normalized count cut point of 9.214) and ACOX1 (D; log2 normalized count cut point of 10.38). P values calculated with the log-rank test. E and F, GSEA of KEGG pathways showing enrichment of oxidative phosphorylation (E) and FA metabolism (F) in the MEER responder cell line in comparison with the MOC2 nonresponder cell line.
