HTRA2 and hepatocellular carcinoma: Among the 9 genes, ATG7, ATG9A, BNIP3L, HTRA2, MAP1LC3B2, TFE3, TIGAR, and TOMM70 were significantly correlated with B cell, CD8+ T cell, CD4+ T cell, macrophage, neutrophil, and dendritic cell infiltrations in HCC, while GABARAPL1 was inversely correlated with these six immune infiltration cells (Figure 8).
