ABSTRACT

The fatty acid desaturase 2 (FADS2) gene encodes delta-6 desaturase (D6D) and is a member of the fatty acid desaturase gene family.D6D is the key enzyme catalyzing the transformation of linoleic acid and α-linolenic acid to long-chain polyunsaturated fatty acid (LC-PUFA).LC-PUFA play a crucial role in regulating the glycolipid metabolism of living organisms.In recent years,the activity of D6D and the single nucleotide polymorphism (SNP) of FADS2 gene have become a hot topic in the research on glycolipid metabolism.This article reviews the role of FADS2 gene in glycolipid metabolism.

ABSTRACT

The effect of the dietary intake of purple-corn extract (EMM) as a source of anthocyanins and the oral supplementation of chia oil (CH), rich in α-linolenic acid on the lipid metabolism of the mammary glands were evaluated by gene expression SREBP-1, Δ6D Δ5D in 36 nursing rats distributed in olive oil (OL), chia oil (CH), olive oil - EMM (EMM OL +) or chia oil - EMM (CH + EMM) treatments. Gene expression of SREBP-1 was similar in OL and CH, increasing in presence of EMM; suggesting that under this conditions, CH and OL oils have similar effect on SREBP-1, while anthocyanins upregulate the gene expression. ALA inhibited the expression of desaturases, and the anthocyanins imaaproved Δ5D expression at control levels similar or higher in the case of Δ6D.


Se evaluó el efecto dietario de un extracto de maíz morado (EMM) como fuente de antocianinas y la suplementación oral de aceite de chía (CH), rico en ácido α-linolénico sobre la expresión génica de SREBP-1, Δ5D y Δ6D en en glándula mamaria de 36 ratas nodrizas distribuidas en cuatro tratamientos: aceites de oliva (OL), CH, OL + EMM o CH + EMM. La expresión de SREBP-1 fue similar en OL y CH, incrementándose en presencia de EMM. La expresión de Δ5D y Δ6D fue mayor en OL que en CH, donde incrementó en presencia de EMM, sugiriendo que bajo estas condiciones los aceites CH y OL tienen efectos similares sobre la expresión de SREBP-1 mientras las antocianinas regulan al alza dicha expresión. ALA inhibió la expresión de las desaturasas y la presencia de antocianinas aumentó la de Δ5D a niveles similares al control, o superiores en el caso de Δ6D.
