Serine protease inhibitors (serpins) mediate many biological processes, including immune responses to pathogenic infection. In this study, a member of the serpin superfamily was identified from the common poultry parasite Eimeria tenella by expressed sequence tag analysis and the rapid amplification of cDNA ends technique. The full-length cDNA was 1,918 bp(More)
Apical membrane antigen-1 (AMA1) is a micronemal protein of apicomplexan parasites that appears to be essential during the invasion of host cells. In this study, a full-length cDNA of AMA1 was identified from Eimeria tenella (Et) using expressed sequence tag and the rapid amplification of cDNA ends technique. EtAMA1 had an open reading frame of 1608 bp(More)
The precocious lines of Eimeria spp. have unique phenotypes. However, the genetic basis of the precocious phenotype is still poorly understood. The identification of Eimeria genes controlling the precocious phenotype is of immense importance in the fight against coccidiosis. In the present study, a novel gene of Eimeria maxima was cloned using rapid(More)
Development of an in vitro Eimeria (E.) tenella model could be valuable as a tool for vaccine, coccidiostats or molecular biology research. 1.0 × 10,000 sporozoites per 0.1 mL were inoculated into the allantoic cavity of ten-day-old chicken embryos. The complete life-cycle of E. tenella was accomplished in eight-nine days at 37 °C and 70% humidity. The(More)
Viral fusogenic membrane glycoproteins (FMGs) are new therapeutic genes for the control of tumor growth, the cellular mechanisms mediating cell death is non-apoptotic. However, the precise molecular mechanism remains to be elucidated. Here, we showed overexpression of HSP70 in HL-60 cells mediated by Gibbon Ape leukemia virus hyperfusogenic envelope protein(More)
Interferon-gamma(IFN-gamma) plays an important role in the immunomodulation and growth inhibition of many tumor cells, but its clinical application is limited by its systemic toxicity. Ad/hIFN-gamma, a nonreplicating adenoviral vector encoding human IFN-gamma, has been reported to inhibit tumor growth in vitro and in a xenograft model. In this study, the(More)
Interferon-γ (IFN-γ) is regarded as a potent antitumor agent, but its clinical application is limited by its short half-life and significant side effects. In this paper, we tried to develop IFN-γ gene therapy by a replication defective adenovirus encoding the human IFN-γ (Ad-IFNγ), and evaluate the antitumoral effects of Ad-IFNγ on nasopharyngeal carcinoma(More)
Protein disulfide isomerase (PDI) and PDI-like proteins are members of the thioredoxin superfamily. They contain thioredoxin-like domains and catalyze the physiological oxidation, reduction and isomerization of protein disulfide bonds, which are involved in cell function and development in prokaryotes and eukaryotes. In this study, EtPDIL, a novel PDI-like(More)
The pedunculopontine nucleus (PPN) is a new deep brain stimulation target for treating Parkinson's disease (PD). But the alterations of the PPN electrophysiological activities in PD are still debated. To investigate these potential alterations, extracellular single unit and local field potential (LFP) activities in the PPN were recorded in unilateral(More)
The genome sequences of Eimeria tenella have been sequenced, but >70% of these genes are currently categorized as having an unknown function or annotated as conserved hypothetical proteins, and few of them have been studied. In the present study, a conserved hypothetical protein gene of E. tenella, designated EtCHP559, was cloned using rapid amplification(More)
