Critical role of PBEF expression in pulmonary cell inflammation and permeability.

Previous studies in our lab have identified pre-B-cell colony enhancing factor (PBEF) as a novel biomarker in acute lung injury. This study continues to elucidate the underlying molecular mechanism of PBEF in the pathogenesis of acute lung injury in pulmonary cell culture models. Our results revealed that IL-1beta induced PBEF expression in pulmonary vascular endothelial cells at the transcriptional level and a -1535 T-variant in the human PBEF gene promoter significantly attenuated its binding to an IL-1beta-induced unknown transcription factor.

Structure-function relationship research of glycerol backbone-based cationic lipids for gene delivery.

Transfection activities of two series of synthetic glycerol backbone-based cationic lipids were studied as gene delivery carriers. The variable length of hydrocarbon chains, diverse quaternary ammonium heads, different linkage, as well as alternative anion combined with them allowed to find how these factors affect cationic lipids on their gene delivery performance. The structure-function relationship of the synthetic glycerol backbone-based cationic lipids was discussed, and the transfection efficiency of some of the cationic liposomes was superior or parallel to that of two commercial transfection agents.

Carbamate-linked cationic lipids for gene delivery.

Series of cationic lipids 1a-p, with variable length of hydrocarbon chains, alternative quaternary ammonium heads, carbamate linkages between hydrocarbon chains and quaternary ammonium heads, as well as different anion combined with them, were synthesized for liposome-mediated gene delivery. Two plasmid DNAs, pGL3-control and pGFP-N2, were transferred by cationic liposomes formed from the above cationic lipids into five mammalian cell lines, and the transfection efficiency of some of the cationic liposomes was superior or parallel to that of two commercial transfection agents, Lipofectamine2000 and Sofast.

Estrogen receptor alpha mediates acute potassium channel stimulation in human coronary artery smooth muscle cells.

The pleiotropic effects of estrogen are mediated via stimulation of two estrogen receptor (ER) subtypes, ERalpha and ERbeta. Although a number of studies have identified expression of one or both subtypes in estrogen target tissues, fewer studies have correlated ER expression with a functional role of these proteins in regulating cellular excitability. In the present study, we have combined cellular fluorescence, immunocytochemistry, and molecular expression techniques with single-channel patch-clamp studies to determine which ER mediates estrogen-stimulated potassium channel activity in human coronary artery smooth muscle cells (HCASMC).

Inhibition of B16 melanoma growth in vivo by retroviral vector-mediated human ribonuclease inhibitor.

Human ribonuclease inhibitor (hRI) can inhibit angiogenesis by reversibly binding angiogenin, a member of the RNaseA superfamily, and by suppressing the expression of basic fibroblast growth factor (bFGF). Angiogenesis is necessary for the growth and metastasis of tumors. To study the links between hRI, angiogenesis, and melanoma growth, the hRI gene was intravenously administered to mice in a recombinant retroviral vector, and expression of the hRI gene was induced to block melanoma angiogenesis.

[Transfection and expression of hRI gene on human umbilical blood stem cells and gene therapy for mouse melanoma].

In order to explore the transfection and expression of hRI gene on human umbilical blood stem cells, and observe it's effect on the tumor growth. After enriching human umbilical cord blood CD34+ cells with a high-gradient magnetic cell sorting system (MACS), transfected them with supernatant of retrovirus containing human Ribonuclease inhibitor (hRI) cDNA. Hematopoietic progenitor clonogenic assay and PCR were used to evaluate transfection efficiency, and Western-blot and immune fluorescence were used to evaluate the expression quantity of hRI gene after transfection.

[Anti-oxidative effect of ribonuclease inhibitor by site-directed mutagenesis and expression in Pichia pastoris].

Human placental ribonuclease inhibitor is an acidic protein of Mr approximately 50 kDa with unusually high contents of leucine and cysteine. It is a cytosolic protein that protects cells from the adventitious invasion of pancreatic-type ribonuclease. HRI has 32 cysteine residues, and the oxidative formation of disulfide bonds from those cysteine residues is a rapid cooperative process that inactivates HRI.
