Fig. 4From: Xanthine dehydrogenase as a prognostic biomarker related to tumor immunology in hepatocellular carcinomaAnalysis of the correlation between XDH expression and immune cell infiltration levels in HCC tissue using the Tumor IMmune Estimation Resource (TIMER) database. A. XDH expression had a significant positive correlation with tumor purity (rho = 0.119, p = 0.026) and CD8 + T cells (rho = 0.157, p = 0.003) and a significant negative correlation with the levels of infiltrating B cells (rho = − 0.178, p = 0.001) and DCs (rho = − 0.179, p = 0.001). B XDH was correlated with the exhausted T cell markers PDCD1 (r = 0.174, p = 1.18e−3) and CTLA4 (r = − 0.212, p = 6.96e−5)Back to article page
