To establish the relevance of ITGB1 and the Wnt/β‐catenin signaling pathway in human GC, we stratified patients in the TCGA‐STAD/ACRG/GSE15459 cohorts by ITGB1 expression and found a significantly high correlation between ITGB1 and the Wnt/β‐catenin signaling pathway (Figure 3E–G, p < 0.001). The gene discussed is ITGB1; the disease is gastric cancer.
