Neuroprotective Sirtuin ratio reversed by ApoE4.
The canonical pathogenesis of Alzheimer's disease links the expression of apolipoprotein E ε4 allele (ApoE) to amyloid precursor protein (APP) processing and Aβ peptide accumulation by a set of mechanisms that is incompletely defined. The development of a simple system that focuses not on a single variable but on multiple factors and pathways would be valuable both for dissecting the underlying...
متن کاملD-galactosamine/lipopolysaccharide-induced hepatotoxicity downregulates sirtuin 1 in rat liver: role of sirtuin 1 modulation in hepatoprotection.
D-Galactosamine/Lipopolysaccharide (D-GalN/LPS) is a well known model of hepatotoxicity that closely resembles acute liver failure (ALF) seen clinically. The role of sirtuin 1 in this model has not yet been documented. However, there have been a number of studies about the cytoprotective effects of resveratrol, a SIRT1 activator, in the liver. This study was aimed at elucidating the roles of SI...
متن کاملSirtuin 1 and sirtuin 3: physiological modulators of metabolism.
The sirtuins are a family of highly conserved NAD(+)-dependent deacetylases that act as cellular sensors to detect energy availability and modulate metabolic processes. Two sirtuins that are central to the control of metabolic processes are mammalian sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3), which are localized to the nucleus and mitochondria, respectively. Both are activated by high NAD(+) leve...
متن کاملNeuroprotective role of estrogens: relationship with insulin/IGF-1 signaling.
Postmenopausal women have an elevated risk of developing a neurodegenerative disease. These clinical observation supported by basic research, suggest that estrogens are neuroprotective. Insulin resistance represents an independent factor in the etiology of age-associated disease and metabolic syndrome should be considered as a contributing factor to the higher post-menopausal vulnerability to n...
متن کامل[Neuroprotective role of silent information regulator 1 in Alzheimer's disease].
Silent information regulator 1 (SIRT1), an NAD(+)-dependent deacetylase, is involved in the regulation of gene transcription, energy metabolism and cell aging. Recent studies have showed that SIRT1 possesses neuroprotective effects, however, it is not very clear how SIRT1 exerts the neuroprotection in Alzheimer's disease (AD). In this review, we summarized the neuroprotective role of SIRT1 in A...
