HSPG2 and neoplasm: The numbers of the significantly expressed genes (FDR [false discovery rate] <0.05) between three types of PLC (HCC: n = 70, ICC: n = 29, CHC: n = 14) and non-tumor liver (n = 7) and of the common differentially expressed genes (DEGs) in two or three subtypes were presented in Venn diagram (Fig. 2B).
