RESV may also modulate the activityof the FOXO transcription factors via AKT and through phosphorylation function via the phosphorylation and activation of I B from the cytop lasm, allow ing nuclear translocation and activation of target genes.Akt is also imp licated in the regulation of mTOR, which is involved in the Bicalutamide control of cell growth, lifespan, agerelated diseases and obesity. There is ev idence that resveratrolis capable of binding to DNA and causing DNA damage. For example, it has been demonstrated that RESV induces S phase arrest and phosphorylation of HA.ATM is a protein that is known to be a central mediator of responses to DNA double strand breaks and subsequent replication stress.Previous studies demonstrating high SIRT levels in the embryonic brain suggest that it might have a ro le in neuronal andor brain development.This idea is consistentwith some of the phenotypes associated with SIRT knockout mice, who show developmen tal defects and in which postnatal survival is infrequent. As in other mammalian cells SIRT promo tes survival and stress to lerance in cen tral nervous system neurons.In the adult rat brain, SIRT can be found in the hippocampus, cerebellum and cerebral cortex. Interesting ly, SIRT expression is regulated by oxidative stress, since the antiox idantvitamin E has been shown to reduce oxidative damage and reduction of SIRT caused by a high fat and sugar diet, with the subsequent restoration of SIRT levels. Th is study suggests that SIRT levels in the brain are affected by oxidative stress and energy homeostasis.When SIRT was inactivated by sirtinol af ter ischemic preconditioningor RESV pretreatmen t, neuroprotection was abolished.Prev ious studies have reported that the benef icial effects of RESV against th is neurotoxin might be attributed to its antioxidantactivity. However, severalfindings in par ticular suggest that the neuroprotective effects of SIRT could be extended to degenerating neurons.Fur thermore, RESV decreased cell death associatedwith neurons cultured from mutant huntingtin knockin mice in a manner that could be reversed by two SIRT inh ibitors, sirtinol and nicotinamide.RESV inhibits the degradation of the cy toplasmatic protein I B and the translocation of the subunit p to the nucleus that is induced by the amy loid. This result connects the known role of SIRT in modulating NF B signalling may resu lt in other benef icial effects such as antiinflammation,with inf lammation being another con tributory factor in the neurodegenerative process of this disease.Likew ise, it has been reported that SIRT is upregulated in mouse models of AD.In the inducible p transgenic mouse, a model of AD and tauopathies, RESV reduced neurodegeneration in the hippocampus and prevented learning impairment. Furthermore, over expression of SIRT via a len tiv irus in thehippocampusof p transgenic mice conferred significantneuroprotection.Accordingly, an increase in SIRT activation may be a potential target for the treatment of neurodegenerative disorders.Another possible link between SIRT and AD comes from the poten tial benefits of CR on AD symptoms and progression.It has been hypothesised that high caloriediets are associated with the risk of AD, and caloric Aspirin restriction.
