We further explored the effect of FBLN2 on tumor immunity through TISIDB and found that the expression of FBLN2 was positively correlated with the abundance of TILs in HCC (Figure 6C), and patients with high FBLN2 expression had stronger immune infiltration than those with low FBLN2 expression based on a CIBERSORT analysis and ssGSEA (Figure 6D,E). This evidence concerns the gene FBLN2 and neoplasm.
