DCAF1 and hepatocellular carcinoma: To further investigate the molecular mechanism by which DCAF1 regulates HCC progression, proteins that may bind to DCAF1 were extracted by coIP in HepG2 cells overexpressing DCAF1 and then subjected to analysis with liquid chromatography and high-throughput mass spectrometry (LC–MS/MS) (Figure S3A, Supplementary Table 8).
