Caenorhabditis elegans DJR-1.2, a homolog of human DJ-1, has recently been demonstrated to be a novel glyoxalase and protects worms against glyoxals. Here, we report that expression of DJR-1.2 is substantially increased during starvation as well as in the dauer stage. The induction of DJR-1.2 led to increased glyoxalase activity in the dauer state, thereby increasing protection against glyoxals. The induction is regulated by DAF-16, a transcriptional regulator implicated in oxidative stress and normal lifespan.
秀丽隐杆线虫 DJR-1.2 是人类 DJ-1 的同源物,最近被证明是一种新型的醛糖还原酶,可保护线虫免受醛糖的侵害。在这里,我们报告说,DJR-1.2 的表达在饥饿和 dauer 阶段都会显著增加。DJR-1.2 的诱导导致 dauer 状态下醛糖还原酶活性增加,从而增加对醛糖的保护。这种诱导受 DAF-16 的调控,DAF-16 是一种参与氧化应激和正常寿命的转录调节剂。
