We then assessed DKK3 protein expression pattern by immunostaining on a human tissue microarray from a resected PDAC cohort.[26] Whereas normal pancreatic tissue appeared mainly negative (score 0), different DKK3‐positive staining patterns (from weak to intense, score 1 to 3) were detected in PanINs and carcinomas. The gene discussed is DKK3; the disease is carcinoma.
