OGT and adenoma: The reverse phase protein analysis (RPPA) of multiple metabolic enzymes in mouse adenomas from Apc/Cre mice with hetero- and homozygous deletion of FASN, performed in our previously published study, showed that downregulation of FASN is associated with a significant decrease in the expression of GFPT1 and OGT, proteins involved in the hexosamine biosynthesis pathway [14].
