(-)-Epigallocatechin-3-gallate (EGCG), a constituent of green tea, has been suggested to have numerous health-promoting effects. On the other hand, high-dose EGCG is able to evoke hepatotoxicity. In the present study, we elucidated the responses of hepatic major antioxidant enzymes and nuclear factor erythroid 2-related factor 2 (Nrf2) rescue pathway to(More)
Chemoprevention that impedes one or more steps in carcinogenesis, via long-term administration of naturally occurring or synthetic compounds, is widely considered to be a crucial strategy for cancer control. Selenium (Se) has chemopreventive effects, but its application is limited due to a low therapeutic index as shown in numerous animal experiments. In(More)
Description: The Handbook of Nanotoxicology, Nanomedicine and Stem Cell Use in Toxicology provides an insight into the current trends and future directions of research in these rapidly developing scientific fields. Written by leading scientists and experts, the Handbook will be of interest to various scientific disciplines including toxicology, medicine,(More)
To gain insight into parthenogenesis in pigs, we report for the first time that using parthenogenetic somatic cells as nuclear donors (PSCNT), the porcine parthenogenetic fetus can develop to gestational day 39. Weight and morphological analysis revealed that PSCNT fetuses were smaller and developmentally retarded when compared to normally fertilized(More)
The present study aimed to observe the effect of rat bone marrow mesenchymal stem cells (MSCs) in vitro on hepatic stellate cell (HSC) RhoA signaling factors and the expression of the cell cycle regulators P27 and cyclin D1. Rat HSC-T6 and fibroblast cells were divided into control, negative control and MSC experimental groups. The cell proliferation rate(More)
Shadoo is a glycoprotein expressed in the adult brain that is an interacting protein of prion protein; however, its function remains to be determined. To elucidate its role in prion pathogenesis, we generated transgenic mice overexpressing wild-type (wt) Shadoo driven by the murine PrP promoter. Expression of the murine Sprn transgene significantly(More)
Cloned pigs generated by somatic cell nuclear transfer (SCNT) show a greater ratio of early abortion during mid-gestation than normal controls. X-linked genes have been demonstrated to be important for the development of cloned embryos. To determine the relationship between the expression of X-linked genes and abortion of cloned porcine fetuses, the(More)
Thioredoxin reductase (TrxR) is a target for cancer therapy and the anticancer mechanism of cisplatin involves TrxR inhibition. We hypothesize that the anticancer drug nedaplatin (NDP), an analogue of cisplatin and a second-generation platinum complex, also targets TrxR. Furthermore, we investigate whether the therapeutic efficacy of NDP can be enhanced by(More)
(-)-Epigallocatehin-3-gallate (EGCG), a major constituent of green tea, can ameliorate metabolic syndrome at least in part through reducing gluconeogenesis and lipogenesis. Green tea extracts, of which EGCG is a key constituent, have been used for weight loss in humans. A potential adverse effect of high-dose EGCG or green tea extracts is hepatotoxicity.(More)
Parthenogenetically activated oocytes cannot develop to term in mammals due to the lack of paternal gene expression and failed X chromosome inactivation (XCI). To further characterize porcine parthenogenesis, the expression of 18 imprinted genes was compared between parthenogenetic (PA) and normally fertilized embryos (Con) using quantitative real-time PCR(More)
