NAGLU and esophageal squamous cell carcinoma: Figure 1C,D show the volcano and heat maps of differential genes between ESCC patients with and without LNM (Supplementary Table S2). A total of six DE-LNM-CCGs were obtained after crossover of LNMGs and CCGs with the DEGs of ESCC and normal samples, including ATR, AANAT, NAGLU, PPARG, TP53, SUMO1 (Figure 1E).
