Basal gland localization and focal distribution of OLFM4-expressing cells in increasing severity of gastric intestinal metaplasia

Anuja Sathe, Rithika S. Meka, Benedikt Geier…·Robert J. Huang

The paper identifies OLFM4 as a marker of high-risk gastric intestinal metaplasia, showing its restricted localization to epithelial glands and focal expansion with disease severity.

A spatially mapped gene expression signature for intestinal stem-like cells identifies high-risk precursors of gastric cancer

Robert J. Huang, Ignacio Alberto Wichmann, Andrew Su…·Hanlee P. Ji

The paper identifies a 26-gene expression signature in high-risk gastric intestinal metaplasia (GIM) that localizes to intestinal stem-like cells and is associated with increased gastric cancer risk.
