To the Editor: The identification of highly polymorphic markers, which are widely distributed throughout the human genome, has allowed the mapping of several disease genes. These markers have been used to analyze the origin, in time and place, of the most prevalent mutations for different diseases, such as cystic fibrosis (Morral et al. 1994), idio-pathic(More)
The true programmed mechanisms of delayed neuronal death induced by global cerebral ischemia/reperfusion injury remain incompletely characterized. Autophagic cell death and programmed necrosis are 2 kinds of programmed cell death distinct from apoptosis. Here, we studied the death mechanisms of hippocampal cornu ammonis 1 neuronal death after a 20-minute(More)
Tyrosine hydroxylase (TH) and brain-derived neurotrophic factor (BDNF), expressed in normal astrocytes, were used in combination for the treatment of Parkinson's disease (PD) symptoms in a rat model. Normal neonatal rat astrocytes were co-transfected with a vector expressing BDNF (AAVBDNF) and a retroviral vector expressing TH (termed TH-BDNF-DA(+) cells),(More)
To explore the antitumor effect of insulin-like growth factor 1 (IGF-I) antisense RNA and the interaction of IGF-I with insulin-like growth factor-binding proteins (IGFBPs) in glioma cells, a recombinant retrovirus expressing IGF-I antisense RNA was constructed and introduced into C6 glioma cells. IGF-I antisense RNA reverses the transformed phenotype in(More)
Salmonella typhi is a pathogen that causes the human disease of typhoid fever. The aim of this study was to investigate the viable but nonculturable (VBNC) state of S. typhi. Some samples were stimulated at 4°C or -20°C, while others were induced by different concentrations of CuSO4. Total cell counts remained constant throughout several days by acridine(More)
Golgi phosphoprotein 3 (GOLPH3) is recently demonstrated to function as an oncogene involved in the development and progression of cancers. However, little is known about GOLPH3 expression and its clinical significance in hepatocellular carcinoma (HCC). The levels of GOLPH3 messenger RNA (mRNA) and protein in HCC cell lines and fresh tissues were determined(More)
An adenovirus, AdCDTK, expressing both bacterial cytosine deaminase (CD) and herpes simplex virus thymidine kinase (HSVTK) was constructed and introduced into glioma cells. AdCDTK selectively rendered glioma cells sensitive to both 5-fluorocytosine (5-FCyt) and ganciclovir (GCV) (termed AdCDTK/5-FCyt-GCV). AdCDTK/5-FCyt-GCV not only potently mediated(More)
Cordycepin has important neuroprotective effects in hypoxic or ischemic insult. However, the direct electrophysiological evidence of cordycepin's neuroprotection from hypoxic or ischemic insult remains unknown. Hence, in this study, the electrophysiological mechanism by which cordycepin protects against ischemic and hypoxic damages has been studied using an(More)
The aim of this study was to investigate the effect of phenylalanine ammonia lyase (PAL) and isochorismate synthase (ICS) on free salicylic acid (FSA) or total salicylic acid (TSA) content, and the effect of endogenous SA on baicalin and baicalein accumulation in Scutellaria baicalensis Georgi, respectively. We amplified partial sequences of PAL and ICS(More)
To characterize biochemically the lipid metabolism-regulating acyl-CoA binding protein (ACBP) from the industrially-important fungus Aspergillus oryzae. A full-length cDNA encoding a candidate ACBP from A. oryzae (AoACBP) was cloned and expressed in Escherichia coli as a maltose-binding protein (MBP) fusion protein. The MBP-AoACBP protein was purified by an(More)
