Figure 7. Genomic alterations of differentially expressed cadherin 1 (CDH1)/2/4/7/11/12/13/15 genes in breast cancer. (A) The cBioPortal database was used to reveal levels of gene amplification, deep deletions, and associated nucleotide substitutions of the CDH1/2/4/7/11/12/13/15 genes in breast cancer progression in the METABRIC dataset. (B) Correlation plot of the CDH1/2/4/7/11/12/13/15 genes in breast cancer (cBioPortal) database. Insignificant correlation values were displayed by crosses; p<0.01 was considered statistically significant. (C) Protein-protein interactions (PPIs) of CDH1/2/4/7/11/12/13/15 (STRING database). Highly interacting proteins were represented as hub protein nodes in the PPI network.
