AADAC is upregulated in CRC liver metastases and associated with poor prognosis. A GO analysis of the 13 most enriched lipid metabolism-related genes upregulated in LMs. B Fold change, p value and FDR of the 5 most enriched genes involved in lipid metabolic processes. C Bioinformatic analysis comparing AADAC expression levels between paired PTs and LMs from CRLM patients in 3 GEO datasets: GSE81582 (n = 19), GSE14297 (n = 18), and GSE49355 (n = 20). D Relative AADAC mRNA levels in paired PTs and LMs from CRLM patients (n = 19). E Protein expression of AADAC in paired PTs and LMs from CRLM patients (n = 10). F IHC staining of AADAC expression in paired PTs and LMs from CRLM patients (n = 157). The upper scale bar represents 500 μm. The lower scale bar represents 100 μm. G-H Relative mRNA (G) and protein (H) levels of AADAC in paired PTs and LMs from an orthotopic CRLM mouse model (n = 4). I Kaplan–Meier plots of OS and RFS after hepatectomy in CRLM patients stratified by AADAC expression in LMs and PTs. Significance was calculated by a two-tailed ratio t test (C-D, right of F, G). p value < 0.001 (***), p value < 0.01 (**), p value < 0,05 (*), ns (not significant)
