Comparison of FSTL1 expression level in adjacent renal tissues and paired tumor tissues of the ccRCC patients.
(A) IHC scores of FSTL1 immunostaining in tumors and adjacent renal tissues of patients with rs1259293 TT genotype (n = 47) and those with rs1259293 TC/CC genotypes (n = 18). (B) The levels of FSTL1 mRNA in adjacent renal tissues of 20 newly enrolled patients from the 47 patients with rs1259293 TT genotype and all the 18 patients with rs1259293 TC/CC genotypes. IHC, immunohistochemistry.
