GPT and breast angiosarcoma: We also analyzed YAP expression with several serum parameters reflecting liver fitness, such as alkaline phosphatase (ALP), glutamic-pyruvic transaminase (ALT), glutamic oxaloacetic, transaminase (AST), γ-glutamyl transpeptidase (GGT), direct bilirubin (DBIL), total bilirubin (TBIL), and total bile acid (TBA); however, none of these factors showed significant correlation with YAP expression in BA patients (Supplementary Table 2).
