Functional reprogramming of a differentiated cell toward pluripotency may have long-term applications in regenerative medicine. We report the induction of dedifferentiation, associated with genomewide programming of gene expression and epigenetic reprogramming of an embryonic gene, in epithelial 293T cells treated with an extract of undifferentiated human NCCIT carcinoma cells. 293T cells expos...
INTRODUCTION Nasopharyngeal carcinoma (NPC) is a common malignant tumor of the head and neck. The STGC3 gene is related to development of nasopharyngeal cancer. The aim of this study is to explore the promoter region of the STGC3 gene. MATERIAL AND METHODS The bioinformatic technique was applied to predict its promoter region and construct the gene promoter region luciferase for the gene vect...
During a comparison of the infectivity of mNDK, a CD4-independent human immunodeficiency virus type 1 (HIV-1) strain, to various cell lines, we found that HeLa cells were much less susceptible than 293T and TE671 cells. Hybridoma cells between HeLa and 293T cells were as susceptible as 293T cells, suggesting that cellular factors enhance the mNDK infection in 293T cells. By screening a cDNA exp...
Acrolein is a highly reactive alpha,beta-unsaturated aldehyde produced endogenously during lipid peroxidation and naturally distributed pervasively in living environments, posing serious threats to human health if not properly metabolized. In this study, we report aldose reductase-like-1 (ARL-1) as a novel enzyme that catalyzes the reduction of acrolein and protects cells from their toxicity. U...
The Ebola virus envelope glycoprotein (GP) derived from the pathogenic Zaire subtype mediates cell rounding and detachment from the extracellular matrix in 293T cells. In this study we provide evidence that GPs from the other pathogenic subtypes, Sudan and Côte d'Ivoire, as well as from Reston, a strain thought to be nonpathogenic in humans, also induced cell rounding, albeit at lower levels th...
lentiviral vectors are among the promising viral based-vectors in gene therapy applications, but the efficiency of their targeting needs to be improved. (strept)avidin-biotin adaptor system is a novel approach to modify the lentiviral envelope for better targeting properties. herein, we describe utilization of this adaptor system by designing a candidate envelope protein-bearing biotin acceptor...
OBJECTIVES Lentiviral vectors have been used successfully to rapidly produce decigram quantities of active recombinant proteins in mammalian cell lines. To optimize the protein production platform, the roles of Ubiquitous Chromatin Opening Element (UCOE), an insulator, and selected promoters were evaluated based on efficiency and stability of foreign gene expression mediated by lentiviral vecto...
