A ERCC1, ERCC2, ERCC3, ERCC4, ERCC5, ERCC6, and ERCC8 mRNA levels in breast cancer (TCGA data) and normal adjacent tissues (GTEx data) using GEPIA. B ERCC1, ERCC2, ERCC3, ERCC4, ERCC5, ERCC6, and ERCC8 mRNA levels in normal, breast cancer, and metastatic breast cancer tissues using TNM Plot. Statistical analyses were conducted using Kruskal–Wallis tests. C ERCC, ERCC2, ERCC3, ERCC4, ERCC5, ERCC6, and ERCC8 protein levels in normal and breast cancer tissues as determined by The Human Protein Atlas
