Biochem/physiol Actions

Linoleic acid increases cell proliferation and gene expression of PPARα and its target genes such as acyl-CoA oxidase in primary duck hepatocytes .
Linoleic acid is an n-6 polyunsaturated essential fatty acid (PUFA) used as a precursor of arachidonic acid (AA) and various prostaglandins. Linoleic acid may be used to improve the delivery and efficacy of anticancer drugs and in cancer protection.
