In mesenchymal gastric cancer cells (GCs), Elongated long-chain fatty acid protein 5 (ELOVL5) and fatty acid desaturase 1 (FADS1) promote unsaturated fatty acid synthesis, but in enteric GC, these genes are suppressed by DNA methylation, rendering the cells resistant to ferroptosis [112]. This evidence concerns the gene ELOVL5 and gastric cancer.
