To analyze the mechanism by which DHA suppresses growth, inhibits angiogenesis, and promotes apoptosis in tumor tissues, expression of the microRNAs (miR-34a-5p, miR-195-5p, miR-30c-5p, and miR-130b-3p) that were up-regulated by DHA and their target mRNAs (Cdk4, Cdk6, VEGF, IKKα, MEK1, E2F3, Rac1, E2F1, and CDC42) were analyzed using qRT-PCR. This evidence concerns the gene VEGFA and neoplasm.
