Finally out! A longstanding project to explore the mechanism behind ectopic crypt formation in polyps when GREM1 is aberrantly expressed in HMPS patients. Turns out it is all to do with stromal remodelling and epithelial-mesenchymal interdependence!

Epithelial GREMLIN1 disrupts intestinal epithelial-mesenchymal crosstalk to induce a wnt-dependent ectopic stem cell niche through stromal remodelling - Nature Communications
The authors show that aberrant epithelial GREM1 expression remodels intestinal stroma to form ectopic stem cell niches in mice. Anti-GREM1 reversed these changes, highlighting a potential strategy for...

Low-coverage whole genome sequencing of low-grade dysplasia strongly predicts advanced neoplasia risk in ulcerative colitis
Background The risk of developing advanced neoplasia (AN; colorectal cancer and/or high-grade dysplasia) in ulcerative colitis (UC) patients with a low-grade dysplasia (LGD) lesion is variable and dif...
