With regard to the epithelial genes related to SCFA absorption, e.g., NHE1, NHE3, sodium-potassium adenosine triphosphatase (Na+/K+ ATPase), vacuolar-type proton adenosine triphosphatase (vH+ ATPase), putative anion transporter 1 (PAT1) anion exchanger 2 (AE2), downregulated in adenoma (DRA), monocarboxylate transporter 1 (MCT1), and monocarboxylate transporter 4 (MCT4) were significantly increased (p < 0.05), whereas NHE2 showed no significant change (p > 0.05) (Figure 7). This evidence concerns the gene SLC16A1 and adenoma.
