Prognostic significance and immune characteristics of CMTM4 in hepatocellular carcinoma

Previous study has shown that chemokine-like factor (CKLF)-like MARVEL transmembrane domaincontaining family member 4 (CMTM4) can bind and maintain programmed cell death ligand 1 (PD-L1) expression to promote tumor progression by alleviating the suppression of tumor-specific T cell activity, suggesting its potential role in tumor immunotherapy
