能量稳态失调是衰老的一个标志性特征,它源于复杂的基因与环境相互作用。在此,我们发现,降低编码烯酰辅酶A水合酶的基因ech - 6的表达,可缓解高脂饮食对秀丽隐杆线虫寿命产生的有害影响,而在正常饮食条件下,ech - 6的基础表达对其生存至关重要。脂质组学分析显示,在ech - 6基因沉默的线虫中补充脂肪,对脂质谱的影响微乎其微,这表明存在一种替代的脂肪利用方式用于能量生成。转录组学进一步表明,溶酶体途径、能量生成以及ech - 6与高脂饮食相互作用所赋予的长寿效应之间存在因果关系。事实上,通过过表达溶酶体脂肪酶lipl - 4来增强内源性脂肪的能量生成,重现了高脂饮食对ech - 6基因沉默线虫寿命的影响。总体而言,这些结果表明,基因ech - 6是代谢灵活性的潜在调节因子,可能成为促进代谢健康和延长寿命的一个靶点。
Deregulated energy homeostasis represents a hallmark of aging and results from complex gene-by-environment interactions. Here, we discovered that reducing the expression of the gene ech-6 encoding enoyl-CoA hydratase remitted fat diet-induced deleterious effects on lifespan in Caenorhabditis elegans, while a basal expression of ech-6 was important for survival under normal dietary conditions. Lipidomics revealed that supplementation of fat in ech-6-silenced worms had marginal effects on lipid profiles, suggesting an alternative fat utilization for energy production. Transcriptomics further suggest a causal relation between the lysosomal pathway, energy production, and the longevity effect conferred by the interaction between ech-6 and fat diets. Indeed, enhancing energy production from endogenous fat by overexpressing lysosomal lipase lipl-4 recapitulated the lifespan effects of fat diets on ech-6-silenced worms. Collectively, these results suggest that the gene ech-6 is potential modulator of metabolic flexibility and may be a target for promoting metabolic health and longevity.
