POFUT1 and adenoma: Previously, depletion of POFUT1 was shown to play a role in differentiation of the proliferative epithelial cells into goblet cells through inactivation of Notch signaling.32 Therefore, we quantified the amount of goblet cells in the adenomas using hematoxylin and eosin‐stained sections to examine this finding in the context of risk of progression.
