Similarly, while we demonstrate here that PCDH7 has little impacts on the expression level of E-cadherin in MCF7 and MDA-MB-436 cells (Figures 2F,G), Chen et al. (2017) reported that E-cadherin expression was significantly downregulated upon PCDH7 depletion in gastric cancer cells. This evidence concerns the gene PCDH7 and gastric cancer.
