CD274 and hepatocellular carcinoma: Similarly, the expression level of LIMS1 (r = 0.568, p = 4.44e-33), FLT3 (r = 0.356, p = 1.67e-12), TNFRSF4 (r = 0.191, p = 2.14e-04), IL18RAP (r = 0.365, p = 4.16e-13), PTGER4 (r = 0.561, p = 3.56e-32), CSF3R (r = 0.428, p = 6.1e-18), HSPA4 (r = 0.225, p = 1.25e-05), NFYC (r = 0.352, p = 3.12e-12) were positively correlated with PDL1 expression in HCC, except of MAPT (r = 0.064, p = 2.22e-01) (Figure 6).
