Specifically, in breast cancer (BRCA), esophageal cancer (ESCA), glioblastoma (GBM), head and neck cancer (HNSC), low-grade glioma (LGG), liver cancer (LIHC), lung adenocarcinoma (LUAD), cutaneous melanoma (SKCM), and uveal melanoma (UVM), elevated BAP31 levels were correlated with poor overall survival (OS). This evidence concerns the gene BCAP31 and breast cancer.
