Figure 1. Bioinformatic analyses suggest that PDIA3 exhibits notably elevated expression in colorectal cancer (CRC) and demonstrates significant associative upregulation with STAT3, CD274, and monocyte/macrophage levels. (A) Widespread expression of PDIA3 across multiple cancer types. Statistical comparison via T-test, P<0.001. (B) Differential expression of PDIA3 within colorectal adenocarcinoma (COAD). Statistical comparison via T-test, P<0.05. (C) Evaluative correlation between PDIA3 and STAT3 expressions in COAD. Correlation coefficient (R) = 0.78, P=0.85E-98. (D) Evaluative correlation between PDIA3 and CD274 expressions in COAD. Correlation coefficient (R) = 0.43, P=2.71E-22. (E) Analysis of the correlation between PDIA3 and macrophages in pan cancer. Statistical comparison via T-test, P<0.05. (F) Survival analysis depicting Overall Survival (OS) (Log-rank P=0.97) and Disease-Free Survival (DFS) (Log-rank P=0.35) as influenced by PDIA3 expression in COAD.
