UCHL1 and lung adenocarcinoma: To prove the correlation between UCHL1 expression and human disease, through TCGA bioinformatics database analysis, we found that there was a significant difference in the expression of UCHL1 between lung adenocarcinoma and normal lung tissue (*P < 0.05, Fig. 1A, Table 1), and the survival rate of patients with high expression of UCHL1 was significantly lower than that of patients with low expression of UCHL1 (Fig. 1B).
