The isoflavones contained in soy have now been postulated to account for their neuroprotective actions.This investigation, therefore, suggests that while anti apoptotic factor production may not be effective as a standalone treatment, in conjunction with othermore effective neuroprotective elements anti apoptotic factorsmay give critical preservation of neuronal function in a complimentary fashion. It’d even be purchase Dalcetrapib of consid-erable interest to further investigate Bcl xL and XIAP gene distribution in amore subtle/progressive genetic model of HD to assess a possible deferral or protraction of the degenerative process and ultimate death of striatal neurons. Recent studies suggest that nutritional soy is neuroprotective in rat models of cerebral ischemia. We’ve shown that the high soy diet reduces infarct size after permanent middle cerebral artery occlusion in ovariectomized female rats. Nutritional soy isoflavones also improve stroke outcome and decrease stroke measurement in male rats following transient MCAO. Daidzein and genistein, along with their metabolites, are phytoestrogens, natural compounds Gene expression that can mimic some of estrogens results and bind to estrogen receptors. Indeed, the soy isoflavone genistein is neuroprotective in a mouse model of ischemic stroke. Nevertheless, the procedure of soy neuroprotection in mental performance remains to be determined. Estrogen is more successful as a neuroprotective agent in several types of brain damage, including stroke. Pretreatment with a dose of estradiol protects the ischemic cortex against delayed cell death caused by MCAO, lowering both caspase activity and DNA fragmentation in-the ischemic penumbra following permanent MCAO. One possible mechanism Fingolimod supplier for estradiol caused neuroprotection is the fact that it modulates expression of genes involved with control of cell death and apoptosis, including anti apoptotic bcl 2 family proteins. In a permanent MCAO model, estradiol prevents the injury induced down regulation of bcl 2 mRNA. Following tMCAO, bcl 2 mRNA and protein are induced in the ischemic penumbra of both intact females and ovariectomized females treated with estrogen. Transgenic overexpression of bcl 2 in neurons has additionally been shown to decrease infarct size in male mice. Furthermore, overexpression of bcl 2 in adult rat brain enhances neurogenesis and survival-of newborn neurons. The induction and/or preservation of bcl 2 following MCAO may symbolize a survival mechanism for neurons after stroke and may account for at least some of the effects of estrogen. Following recent clinical studies suggesting possible negative health consequences of hor-mone therapy, the usage of as an all-natural option to estrogen replacement after menopause soy has increased. Whether soy is acting like estrogen in the brain to supply neuroprotection is uncertain.
