Study Publishes New Insights on Goblet Cell Differentiation in Colorectal Cancer — University of Oxford, Medical Sciences Division

The research addresses the long-recognized poor prognosis of relatively undifferentiated cancers, suggesting that selection against differentiation and in favour of uncontrolled growth is a powerful driver of cancer progression. Goblet cells, which provide the mucous surface of the gut, are a crucial focus of this study. When present in colorectal cancers, these cancers are termed mucinous.

Key findings from the study include:

Nearly 80 CRC-derived cell lines are classified into five categories based on the levels of MUC2 (the main mucous product of goblet cells) and TFF3 (an associated gene product).
Identification of five distinct patterns of MUC2 and TFF3 expression, which can be easily identified in tumour specimens, allowing for a finer characterisation of CRCs concerning goblet cell differentiation.
It was discovered that approximately 30% of all CRCs express TFF3 but not MUC2, a previously unrecognised subgroup.
Highlighting the role of LGR5 in controlling differentiation rather than direct control of cell growth, challenging previous assumptions.
