Recent studies have demonstrated direct reprogramming of fibroblasts into a range of somatic cell types, but to date stem or progenitor cells have only been reprogrammed for the blood and neuronal lineages. We previously reported generation of induced hepatocyte-like (iHep) cells by transduction of Gata4, Hnf1α, and Foxa3 in p19 Arf null mouse embryonic(More)
In the rapid development of nanoscience and nanotechnology, many researchers have discovered that metal oxide nanoparticles have very useful pharmacological effects. Cuprous oxide nanoparticles (CONPs) can selectively induce apoptosis and suppress the proliferation of tumor cells, showing great potential as a clinical cancer therapy. Treatment with CONPs(More)
DNA-mediated immunization has been recognized as a new approach for prevention and treatment of hepatitis B virus (HBV) infection. However, the side effects of this approach have not been well described. Here we report that DNA-mediated immunization by intramuscular injection of plasmid DNA encoding HBV surface antigen (HBsAg) induced long-term persistence(More)
Although embryonic stem (ES) cell-derived hepatocytes have the capacity for liver engraftment and repopulation, their in vivo hepatic function has not been analyzed yet. We aimed to determine the metabolic function and therapeutic action of ES cell-derived hepatocytes after serial liver repopulations in fumaryl acetoacetate hydrolase knockout (Fah(-/-))(More)
Hepatocellular carcinoma (HCC), the most common primary malignant tumor of the liver, often associated with the dysregulation of transcriptional pathways involved in cell growth and differentiation. The hematopoietically expressed homeobox protein (Hhex) is an important transcription factor throughout liver development and is essential to liver bud(More)
Identification of the cellular origin of primary liver cancer remains challenging. Some data point toward liver stem cells (LSCs) or liver progenitor cells (LPCs) not only as propagators of liver regeneration, but also as initiators of liver cancer. LSCs exhibit a long lifespan and strong duplicative potential upon activation and are inclined to accumulate(More)
AIM To make immunopathological study of hepatitis B virus transgenic mice line C57-TgN (HBV adr2.0) SMMU. METHODS Twenty transgenic C57-TgN mice of SPF grade and corresponding control mice C57BL/6 were used for the study. The expressions of CD3, CD4 and CD8 on lymphocytes in peripheral blood from transgenic and normal C57BL/6 mice were detected by flow(More)
AIM To establish a mice model harboring hepatitis B virus x gene (adr subtype) for studying the function of hepatitis B virus X protein, a transactivator of viral and cellular promoter/enhancer elements. METHODS Expression vector pcDNA3-HBx, containing CMV promoter and hepatitis B virus x gene open reading fragment, was constructed by recombination DNA(More)
To generate the transgenic mice expressing cyclization recombination enzyme, the recombinant gene, in which the coding region of cre gene is derived by the promoter of mouse Mx gene, was microinjected into pronuclei of fertilized mouse eggs. Founders of transgenic mice harbouring the recombinant gene were screened by polymerase chain reaction (PCR) at(More)
The Cre recombinase and its activity in C57-TgN(Mx-Cre) transgenic mice is studied by polymerase chain reaction (PCR), Western blot, immunohistochemistry, immunogold electron microscopy and Southern blot. C57-TgN(Mx-Cre) transgenic mice harbouring cre gene in genomic DNA is demonstrated by PCR, and these mice which are induced by INF-alpha 1b could express(More)
