Identification and validation of differentially expressed genes between Claudin15^−/− and Claudin15^+/+ type mammary glands. A, Differentially expressed genes between Claudin15^−/− and Claudin15^+/+ type mammary glands. The top enriched genes (P < .05), identified from the training set used to predict the validation set, are listed in a heat map. B, Enrichment analysis of pathways for differentially expressed genes. Pathway analysis was predominantly based on the KEGG database. P values < .05 using the chi‐square test were indicated as statistically significant. C, Verification of differentially expressed genes between Claudin15^−/− and Claudin15^+/+ type mammary glands. The error bar indicates the standard error of mean (SEM). *P < .05
