  6. commonly overexpressed COX in cancer (~90% of colon cancer patients) can be taken advantage to suppress cell growth by knocking down delta-5-desaturase (D5D, a key enzyme that converts DGLA to arachidonic acid). In addition, D5D knockdown along with DGLA supplement may enhance the efficacy of chemotherapeutic drugs PMID: 27101738
  7. In minor allele carriers of FADS1 and FADS2, plasma arachidonic acid (ARA) content was elevated only at the highest level of ARA consumed in infant formula. ARA level in plasma is reduced by low ARA consumption and by minor alleles in FADS in infants fed ARA-containing formula. PMID: 27276431

  12. Results indicate that genetic variation in the FADS1 gene, rs174546, influences blood pressure via arachidonic acid and body mass index.
