There are no effective medications for delaying the progress of Alzheimer's disease (AD), the most common neurodegenerative disease in the world. In this study, our results with C. elegans showed that rose essential oil (REO) significantly inhibited AD-like symptoms of worm paralysis and hypersensivity to exogenous 5-HT in a dose-dependent manner. Its main components of β-citronellol and geraniol acted less effectively than the oil itself. REO significantly suppressed Aβ deposits and reduced the Aβ oligomers to alleviate the toxicity induced by Aβ over-expression. Additionally, the inhibitory effects of REO on worm paralysis phenotype were abrogated only after skn-1 RNAi, but not daf-16 and hsf-1 RNAi. REO markedly activated the expression of gst-4 gene, which further supported SKN-1 signaling pathway was involved in the therapeutic effect of REO on AD C. elegans. Our results provided direct evidence on REO for treating AD on an organism level and relative theoretical foundation for reshaping medicinal products of REO in the future.

Organismal lifespan is highly plastic in response to environmental cues, and dietary restriction (DR) is the most robust way to extend lifespan in various species. Recent studies have shown that sex a...
Dystrophin-like dys-1 gene expression increases in the body-wall muscles of Caenorhabditis elegans (C. elegans) after spaceflight. Here, we utilized a dys-1(cx18) mutant to analyze the molecular adapt...
Oxidative stress is linked to many pathological conditions including the loss of dopaminergic neurons in Parkinson's disease. The vast majority of disease cases appear to be caused by a combination of...

Accumulation of blood in the SUBDURAL SPACE with delayed onset of neurological symptoms. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.
A class of traumatic stress disorders with symptoms that last more than one month. There are various forms of post-traumatic stress disorder, depending on the time of onset and the duration of these stress symptoms. In the acute form, the duration of the symptoms is between 1 to 3 months. In the chronic form, symptoms last more than 3 months. With delayed onset, symptoms develop more than 6 months after the traumatic event.
Proteins from the nematode species CAENORHABDITIS ELEGANS. The proteins from this species are the subject of scientific interest in the area of multicellular organism MORPHOGENESIS.
Non-optimal interval of time between onset of symptoms, identification, and initiation of treatment.
A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-IV)
