Fatty acids (FAs) 1 are energy-rich molecules, which play important metabolic roles. They
are also an integral part of cells as membrane components, which can influence fluidity and
receptor or channel function. Over the past 10 years, it has become evident that FAs can
also act as signaling molecules involved in regulating gene expression. For the most part,
these target genes encode proteins with roles in FA transport or metabolism. The
corresponding change in the amount of specific proteins is an adaptative process that the …
