CRC progression was assessed by measuring tumor burden, mucosal plaque lesions, aberrant crypt foci (ACF), cecal short-chain fatty acids (SCFAs), oxidative stress markers, liver enzymes, inflammatory cytokine (IL-6), matrix metalloproteinase-9 (MMP-9), DNA fragmentation, histological changes, and PCNA expression. Here, IL6 is linked to colorectal carcinoma.
