Except for GABARAPL1, the remaining 8 genes were positively correlated with B cell, CD8+ T cell, CD4+ T cell, macrophage, neutrophil, and dendritic cell infiltrations in HCC by using the TIMER database, which indicated that these mitophagy signature may play a vital role in immune activity. The gene discussed is GABARAPL1; the disease is hepatocellular carcinoma.
