NAD(+)-dependent sirtuin deacetylases have emerged as potential therapeutic targets for treatment of human illnesses such as cancer, metabolic, cardiovascular, and neurodegenerative diseases. The benefits of sirtuin modulation by small molecules have been demonstrated for these diseases. In contrast to the discovery of inhibitors of SIRT1, -2, and -3, only(More)
BACKGROUND a small number of reports exist on the cognitive effects of soy isoflavones, the findings from which are mixed. Isoflavone efficacy is dependent upon conversion of glycosides contained in soy foods and supplements to the biologically active aglycons. Of particular interest is the production of the metabolite, equol, which is dependent upon(More)
The family of histone deacetylases (HDACs) has recently emerged as important drug targets for treatment of slow progressive neurodegenerative disorders, including Huntington's disease (HD). Broad pharmaceutical inhibition of HDACs has shown neuroprotective effects in various HD models. Here we examined the susceptibility of HDAC targets for drug treatment(More)
Sirtuin 2 (SIRT2) deacetylase-dependent inhibition mediates neuroprotective reduction of cholesterol biosynthesis in an in vitro Huntington's disease model. This study sought to identify the first brain-permeable SIRT2 inhibitor and to characterize its cholesterol-reducing properties in neuronal models. Using biochemical sirtuin deacetylation assays, we(More)
When pSV2-gpt or pSV2-neo plasmids are introduced into human cells by calcium phosphate coprecipitation, the yield of stable transformants (Gpt+ or Neo+) is increased by irradiating the respective plasmid DNA in vitro with UV (254 nm). To identify specific lesions that can increase the transforming activity of plasmids in human cells we examined pSV2(More)
