CTNNB1 and non-small cell lung carcinoma: The expressions of CDH1 (Fig. 8b) and E-cadherin (Fig. 8c) were also positively correlated at bulk-cell level, while the expression pattern of CTNNB1 at single-cell level (Fig. 8a) showed more similar with that of β-catenin (Fig. 8c) compared with their expressions at bulk-cell level (Fig. 8b) in the four NSCLC epithelial cell lines.
