The results showed that HCC with low MBL2 expression was mainly involved in the cell cycle, DNA replication, miRNAs in cancer, and the vascular endothelial growth factor signaling pathway of the KEGG pathway (Figure 2C) and was enriched in GO-BP terms related to DNA replication, cell cycle checkpoints, chromatin remodeling, and the cell cycle G1/S phase transition (Figure S2B). The gene discussed is MBL2; the disease is cancer.
