Figure 8. The experimental validation of CHRDL1 by IHC. (A) IHC staining of CHRDL1 and CD30 in normal sample and LUAD tissues. (B, C) Validation of association between CHRDL1 expression and TNM stage by IHC. (D) Validation of CHRDL1 expression showing discrimination power between normal samples and LUAD tissues by IHC. (E) Validation of the impact of CHRDL1 expression on overall survival in LUAD patients.
