In addition, PSAP can act as a biomarker in a variety of cancers, including gliomas [19], gastric cancer (GC) [20], colorectal cancer (CRC) [21], gallbladder cancer (GBC) [22], hepatocellular carcinoma (HCC) [23], pancreatic ductal carcinoma (PDAC) [24], malignant pleural mesothelioma (MPM) [25], and fibrosarcoma [26]. This evidence concerns the gene PSAP and glioma.
