Eicosapentaenoic Acid (EPA) is an orally active Omega-3 long-chain polyunsaturated fatty acid (ω-3 LC-PUFA). Eicosapentaenoic Acid exhibits a DNA demethylating action that promotes the re-expression of the tumor suppressor gene CCAAT/enhancer-binding protein δ (C/EBPδ). Eicosapentaenoic Acid activates RAS/ERK/C/EBPβ pathway through H-Ras intron 1 CpG island demethylation in U937 leukemia cells. Eicosapentaenoic Acid can promote relaxation of vascular smooth muscle cells and vasodilation^[1][2][3].

C/EBPβ phosphorylated form is evident in Eicosapentaenoic Acid (EPA; 100 µM; 24 h) treated cells, whereas it was barely detectable in control, and OA or LA treated U937^[1].
Eicosapentaenoic Acid (100 µM; 1, 3, 24 h) causes a significant increase of H-Ras and N-Ras mRNA levels conditioning for 1 and 3 hours. K-Ras mRNA levels were not affected by Eicosapentaenoic Acid^[1].
