USP30 and neoplasm: Next, we studied each lncRNA in our signature and found that AC024060.1, AC105942.1, AL031775.1, USP30-AS1, and MAFG-DT-LNC were merely reported once in BC predictive signatures, like immune-related lncRNA signature [39], epithelial mesenchymal transition-related lncRNA signature [40], tumor-infiltrating B lymphocytes lncRNA signature [41].
