LGR5 and gastric carcinoma: In total, 76% of gastric adenomas and 43% of early gastric carcinomas were positive for LGR5. Lgr5+ cells were found more frequently in low-grade tumors with active Wnt signaling and an intestinal gland type, suggesting that LGR5 is likely involved in the very early stages of Wnt-driven tumorigenesis in the stomach.
