SIRT1, a mammalian ortholog of yeast silent information regulator 2 (Sir2), is an NAD+-dependent protein deacetylase that plays a critical role in the regulation of vascular function. The current study aims to investigate the functional significance of deacetylase activity of SIRT1 in heart. Here we show that the early postnatal hearts expressed the highest(More)
Calcium/calmodulin-dependent protein kinase II (CaM Kinase II) is a known modulator of cardiac pathophysiology. The present review uniquely focuses on novel CaM Kinase II-mediated endothelial cell signalling which, under pathophysiological conditions, may indirectly modulate cardiac functions via alterations in endothelial or endocardial responses. CaM(More)

Safe and efficient gene transfer systems are the basis of gene therapy applications. Non-integrating lentiviral (NIL) vectors are among the most promising candidates for gene transfer tools, because they exhibit high transfer efficiency in both dividing and non-dividing cells and do not present a risk of insertional mutagenesis. However, non-integrating(More)
The rapidly increasing prevalence of diabetes mellitus worldwide is one of the most serious and challenging health problems in the 21st century. Mammalian sirtuin 1 (SIRT1) has been shown to decrease high-glucose-induced endothelial cell senescence in vitro and prevent hyperglycemia-induced vascular dysfunction. However, a role for SIRT1 in prevention of(More)
Glioma-specific transcription of tumor-killing genes has been exploited as a promising gene therapeutic modality in glioma patients. Musashi1 (Msi1) and GFAP gene promoters are both cancer-specific promoters. Optimized HIF-binding site (optHBS) sequence was newly found as efficient as EPO HREs used as enhancer in cancer gene therapy. We constructed(More)
Intercellular adhesion molecule-1 (ICAM-1) plays an important role in the recruitment of leukocytes to the endothelium, which causes inflammation and initiation of atherosclerosis. We have previously shown that endothelium-specific over-expression of class III deacetylase SIRT1 decreases atherosclerosis. We therefore addressed the hypothesis that SIRT1(More)
To investigate the feasibility of conducting a genomic-scale protein labeling and localization study in Escherichia coli, a representative subset of 23 coding DNA sequences (CDSs) was selected for chromosomal tagging with one or more fluorescent protein genes (EGFP, EYFP, mRFP1, DsRed2). We used lambda-Red recombination to precisely and efficiently position(More)
Salt sensitivity of blood pressure (BP) is influenced by genetic and environmental factors. A dietary feeding study was conducted from October 2003 to July 2005 that included a 7-day low-sodium intervention (51.3 mmol sodium/day) followed by a 7-day high-sodium intervention (307.8 mmol sodium/day) among 1,906 individuals who were 16 years of age or older(More)
