Transgenic expression of mutant superoxide dismutase-1 (SOD1) produces an animal model of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disorder. We have previously shown that the mitochondrial-dependent programmed cell death (PCD) pathway, including the redistribution of Bax, the cytosolic release of cytochrome c, and the activation of(More)
Reactive carbonyl species (RCS), such as methylglyoxal (MG) and glyoxal (GO), are synthesized as toxic metabolites in living systems. Mechanisms of RCS detoxification include the glutathione (GSH)-dependent system consisting of glyoxalase I (GLO1) and glyoxalase II (GLO2), and GSH-independent system involving glyoxalase III (GLO3). Hsp31 and DJ-1 proteins(More)
The Parkinson's disease protein DJ-1 is involved in various cellular functions including detoxification of dicarbonyl compounds, autophagy and oxidative stress response. DJ-1 homologs are widely found in both prokaryotes and eukaryotes, constituting a superfamily of proteins that appear to be involved in stress response. Schizosaccharomyces pombe contains(More)
S-adenosylhomocysteine (SAH) is an effective sedative, a good sleep modulator, and a new anticonvulsant. SAH can be synthesized from adenosine and homocysteine by using microbial S-adenosylhomocysteine hydrolase (SAHase). The extremely thermostable SAHase and lactate dehydrogenase (LDH) from Thermotoga maritima were successfully overexpressed in Escherichia(More)
The development of effective oral preparations of 2-methoxyestradiol (2-ME) has been a worldwide problem. In this study, breakthrough progress has been made in oral delivery of 2-ME by encapsulating 2-ME micelles in pH-responsive microspheres. 2-ME micelles with small particle size (58nm) and high drug loading (7.94±0.23%) were successfully prepared and(More)
Derivatives of fullerene (C60) as photosensitizers have rarely been studied as delivery carrier materials. The focus of this study was to explore the potential advantages of diadduct malonic acid-fullerene (DMA-C60) as delivery carrier materials and combination of chemo-phototherapy of some tumors. In this study, DMA-C60 and docetaxel (DTX) were coentrapped(More)
Herpesvirus-associated Ubiquitin-Specific Protease (HAUSP, also called USP7) interacts with and stabilizes Mdm2, and represents one of the first examples that deubiquitinases oncogenic proteins. USP7 has been regarded as a potential drug target for cancer therapy. Inhibitors of USP7 have been recently shown to suppress tumor cell growth in vitro and in(More)
The gene encoding thermostable lactate dehydrogenase (Tm-LDH) was cloned into the plasmid pHsh from Thermotoga maritima, and expressed in Escherichia coli JM 109. The recombinant protein was purified to homogeneity by a simple step, heat treatment. The recombinant enzyme had a molecular mass of 33 kDa. The optimal temperature and pH of Tm-LDH were observed(More)
With the rapid development of computer technologies and medical industries,the sharing and exchanging of medical information has become increasingly important.A framework for integrating heterogeneous, diverse and various medical information systems based on Health Level 7(HL7),ontology and Web services is proposed in this paper.In the paper, we describe(More)
