Notably, UGT1A9, UGT1A1, and UGT1A6 are expressed in the liver and kidney cortex and basally expressed in the colon, while UGT1A10 and UGT1A1 are highly and specifically expressed in the transverse colon and the terminal ileum of the small intestine, indicating that these two proteins may indeed be core drivers of IBD-specific GRNs [20]. This evidence concerns the gene UGT1A10 and inflammatory bowel disease.
