BACKGROUND Hypoxic tumor cells can reduce the efficacy of radiation. Antiangiogenic therapy may transiently "normalize" the tumor vasculature to make it more efficient for oxygen delivery. The aim of this study is to investigate whether the recombinant human endostatin (endostar) can create a "vascular normalization window" to alleviate hypoxia and enhance(More)
BACKGROUND Nonviral vectors are attractively used for gene therapy owing to their distinctive advantages. Our previous study has demonstrated that transfer of human IFNγ gene into nasopharyngeal carcinoma (NPC) by using a novel nonviral vector, minicircle (mc), under the control of cytomegalovirus (CMV) promoter was effective to inhibit tumor growth.(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)
RNase T is one of eight distinct 3'-->5' exoribonucleases present in Escherichia coli. The enzyme plays an important role in stable RNA metabolism, including tRNA end turnover and 3' maturation of most stable RNAs because it is the only RNase that can efficiently remove residues near a double-stranded (ds) stem. In the course of study of its specificity and(More)
Trichomonas vaginalis is a flagellated protozoan, a representative of 1 of the earliest known eukaryotic lineages. Trichomonas vaginalis lacks centrioles but possesses basal bodies. We report here the cell cycle-dependent flagellar dynamics of T. vaginalis. By immunofluorescence, we found that T. vaginalis flagella duplicated during S-phase, segregated(More)
