FDX1 and colon adenocarcinoma: Analysis using the TCGA database showed that FDX1 is positively correlated with immune cell infiltration in colon adenocarcinoma, particularly indicating a higher proportion of CD8+ T cells in tumour tissues compared to adjacent nontumour tissues, while the proportion of CD4+ T cells was opposite, suggesting that FDX1 is a potential target for colon adenocarcinoma immune therapy.148
