Immune checkpoint molecules signal regulatory protein alpha in the development of hepatocellular carcinoma

Figure 2 The expression of signal regulatory protein alpha in adjacent and tumor tissues of hepatocellular carcinoma. A: The overall survival of signal regulatory protein alpha (SIRPα) (The Cancer Genome Atlas, http://gepia.cancer-pku.cn/). High expression of SIRPα is positively correlated with poor prognosis in hepatocellular carcinoma (HCC) patients; B and C: Expression patterns of SIRPα in tumor, stromal and normal tissues of HCC. The expression of SIRPα showed an increasing trend in normal tissues, stromal tissues, and tumor tissues of HCC (http://Lifeome.net/database/hccdb/home.html). SIRPα: Signal regulatory protein alpha.
