At the same time, analysis of ferroptosis-related genes associated normal tissue and gastric cancer tissues screened out 19 FerDEGs: ten of them, i.e., TLR4, KRAS, HSF1, was highly expressed and nine of them, i.e., MUC1, PROM2, MT1G, were lowly expressed in tumor tissues (see Figure 2D). Here, HSF1 is linked to neoplasm.
