Mechanism of PUFA in regulating of gene expression / 生物医学工程学杂志

ABSTRACT

Polyunstaurated fatty acids (PUFAs) not only are essential component of cells in maintaining function and composing organelle, but also control gene transcription of enzymes which are involved in differentiation, growth and metabolism in organisms. Resent studies have been shown that PUFA interact directly with nuclear receptors such as PPARs, LXR, HNF-4, other mechanism are indirect and rest with transcription factors such as SREBP. PUFA affect cell function through diverse pathways. The roles of such factors and PUFA in mediating the nuclear effects are addressed in order to elucidate the mechanism of PUFA in regulating gene expression. Further understanding of gene mechanism of regulation at the level of molecule would prompt the development of nutrition, health and medical treatment.
