P4HB protein expression levels in tumors with differential expression of P4HB. a–i Box plots (left) demonstrated the RNA level of tumors differentially expressing P4HB using GEPIA2. Cutoff value is set to |Log2FC| > 1, P value < 0.05. The HPA database was used to analyze the protein expression level (right) of P4HB in a COAD; b UCEC; c PRAD; d BRCA; e LUSC; f BLCA; g LIHC; h KIRC; i LUAD. *P < 0.05
