ABSTRACT
Many studies utilizing animal models have revealed the genetic and pharmacogenetic modulators of the rate of organismal aging. However, finding routes for healthy aging during extended life remains one of the largest questions. With regards to an antiaging reagent, it has been shown that natural phytochemical syringaresinol (SYR) delays cellular senescence by activating sirtuin1 (SIRT1). Here, it is found that SYR treatment results in metabolic changes similar to those observed during dietary restriction (DR). The DR mimetic effects are mediated by FoxO3a-dependent SIRT1 activation and insulin/insuline growth factor-1 signaling modulation. The direct binding of SYR-FoxO3a is identified and this could partially explain the DR-like phenotype. The report gives a clue as to how the longevity gene involves the DR pathway and suggests that natural phytochemicals applied as a geroprotector mimics DR effects.
