To this end, we reexamined a data set in which we previously analyzed gene expression in human CRC tissues from The Cancer Genome Atlas Colon Adenocarcinoma data collection (TCGA-COAD)41 as it correlates with fusobacterial abundance.1 We first looked at FFAR2 and observed significant correlation between its expression and intratumoral fusobacterial abundance (Figure 5c). This evidence concerns the gene FFAR2 and colorectal carcinoma.
