Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ggi12255-sec-0001" sec-type="section"> <title>Aim</title> <p>Many intracellular components have been implicated in the regulation of redox homeostasis, but homeostasis can be unbalanced by reactive species (RS), which also probably contribute to underlying inflammatory processes. Nuclear factor‐κB (NF‐κB) is a well‐known redox‐sensitive transcription factor that controls the genes responsible for regulating inflammation.</p> </sec> <sec id="ggi12255-sec-0002" sec-type="section"> <title>Methods</title> <p>In the present study, the authors investigated the effect of short‐term salicylideneamino‐2‐thiophenol (SAL‐2) administration on the modulation of pro‐inflammatory NF‐κB through redox regulation in aged rats. In addition, we compared the effects of SAL‐2 and caloric restriction (CR) on inflammation and redox balance. The subjects were 24‐month‐old (old) Fischer 344 rats administered SAL‐2 (10 mg/kg/day) by dietary supplementation or placed on a 30% restricted diet for 10 days, and 6‐month‐old (young) rats fed ad libitum for 10 days.</p> </sec> <sec id="ggi12255-sec-0003" sec-type="section"> <title>Results</title> <p>We found that NF‐κB activation and the expressions of its related genes (vascular cell adhesion molecule‐1, intercellular adhesion molecule‐1, cyclooxygenase‐2 and inducible nitric oxide synthase) were suppressed by SAL‐2 supplementation in old CR rats to the levels observed in young rats. In addition, our molecular studies showed that the inhibitory effect of SAL‐2 on the activation of NF‐κB was mediated by the ability of SAL‐2 to block the nuclear translocations of cytosolic thioredoxin and redox factor‐1.</p> </sec> <sec id="ggi12255-sec-0004" sec-type="section"> <title>Conclusion</title> <p>These findings strongly indicate that SAL‐2 stabilizes age‐related redox imbalance and modulates the signal transduction pathway involved in the age‐associated molecular inflammatory process. <bold>Geriatr Gerontol Int 2015; 15: 211–219.</bold></p> </sec> </abstract>
