The results showed that the expression of RRP12 was significantly correlated with B lymphocytes, CD8 + T lymphocytes, CD4 + T lymphocytes, macrophages, and dendritic cells in HCC (P<0.05), among which B lymphocytes and dendritic cells were significantly correlated, and the correlation between RRP12 expression level and macrophages was not statistically significant (Figure 6). This evidence concerns the gene RRP12 and hepatocellular carcinoma.
