TGFBI and ovarian cancer: ECM-related genes (ρ = 0.56, 95%CI: 0.48–0.62, p < 0.01) and degradation of ECM (ρ = 0.61, 95%CI: 0.54–0.67, p < 0.01) were also significantly positively correlated with TGFBI expression (Figure S6 C and D), suggesting that TGFBI might regulate ECM remodeling in ovarian cancer microenvironment.
