Figure 3. Expression, interactions and functional annotations of ferroptosis regulators in STS. (A) Correlation plot among 16 regulators using Pearson correlation analysis. PPI analysis of ferroptosis regulators. (B) Expression of different ferroptosis regulators between normal samples and STS samples in GSE17674. (C) Functional annotations for 16 ferroptosis regulators. *p < 0.05, **p < 0.01, ***p < 0.001, ****p = 0. Abbreviation: ns: no significance.
