摘要:

以秀丽隐杆线虫模式生物为研究对象, 研究大豆异黄酮染料木素微生物代谢产物左旋-5-羟基-雌马酚对线虫寿命、生殖能力以及抗热应激和抗氧化应激能力的影响。研究结果表明, 浓度为0.1 mmol/L0.2 mmol/L的左旋-5-羟基-雌马酚不仅能够显著延长线虫寿命, 同时还能显著增强线虫耐热和抗氧化应激能力, 而在相同浓度下线虫生殖能力则无明显不良影响。通过进一步对比分析转录物水平以及喂食相应线虫突变体daf-16 (mu86) daf-2 (e1370), 确定左旋-5-羟基-雌马酚延长线虫寿命与DAF-2/DAF-16 Insulin/IGF-1信号转导通路相关。有关左旋-5-羟基-雌马酚显著延长线虫寿命和增强线虫抗性为国内外首次报道。

Abstract:

Caenorhabditis elegans (C. elegans) was used as an animal model to study the effect of (–)-5-hydroxy-equol, a microbial metabolite of isoflavone genistein, on the lifespan, fecundity and resistance against thermal and oxidative stress. The results showed that (–)-5-hydroxy-equol not only significantly increased the lifespan of C. elegans but alsosignificantly enhanced the resistance against thermal and oxidative stress at the concentrations of 0.1 mmol/L and 0.2 mmol/L. However, the fecundity ofC.elegans was not obviously influenced after being exposed to the same concentrations of (–)-5-hydroxy-equol. Furtherstudieson comparative transcriptome analyses and the lifespan of daf-16 (mu86) mutant and daf-2 (e1370) mutantindicated that(–)-5-hydroxy-equol prolonged the lifespan of C.elegansthrough DAF-2/DAF-16 Insulin/IGF-1 signaling pathway.This is the first report that (–)-5-hydroxy-equol was able to increase the lifespan and improve the thermal and oxidative stress tolerance of C. elegans.
