Abstract
Polyethylenimine (PEI) is a polycation widely used for successful gene delivery both in vitro and in vivo experiments. However, different studies showed that PEI could be cytotoxic to transfected cells, and the mechanism of toxicity is poorly understood. Identification of PEI-interacting proteins may help in understanding the toxicity pathways. In this study, we investigated proteins that could interact with PEI in human colorectal adenocarcinoma cells (HT29). In order to identify the proteins interacting with PEI, PEI was immobilized to sepharose beads as solid matrix. The HT29 cell lysate were passed through the matrix. PEI-bound proteins were isolated, and further separation was performed by two-dimensional gel electrophoresis. After gel digestion, proteins were identified by matrix-assisted laser desorption/ionization-time-of-flight (TOF)/TOF mass spectrometry. Our data indicated that most of the identified PEI-interacting proteins such as shock proteins, glutathione-S-transferases, and protein disulfide isomerase are involved in apoptosis process in cells. Thus, although this is a preliminary experiment implicating the involvement of some proteins in PEI cytotoxicity, it could partly explain the mechanism of PEI cytotoxicity in cells.

Abstract
Therapeutic angiogenesis via gene delivery is promising for tissue survival and regeneration after injury or ischemia. A stable, safe and efficient gene vector is essential for successful angiogenesis. We have demonstrated that our newly developed lipopolysaccharide-amine nanopolymersomes (LNPs) have higher than 95% transfection efficiency when delivering pEGFP into mesenchymal stem cells (MSCs). To explore their clinical potential in therapeutic angiogenesis, in this study, we studied their toxicity, storage stability, protection ability to genes and efficacy to deliver therapeutic genes of pVEGF in MSCs and zebrafish. The results show that LNPs can condense pVEGF to form pVEGF-loaded nanopolymersomes (VNPs), and protect pVEGF against DNase digestion in 6 h. Both LNPs and VNPs have low toxicity to MSCs, erythrocytes and zebrafish embryos. LNPs are stable at 4 °C for at least two years with unchanged size and transfection efficiency. MSCs transfected by VNPs continuously synthesize VEGF for at least four days under control, with a peak (21.25 ng ml(-1)) ∼35-fold greater than that for the untreated group. VNPs induce significant and dose-dependent angiogenesis in zebrafish without causing death, deformity or delay in growth and development, and the induced maximal vessel area of subintestinal vessel plexus is 2.5-fold higher than that for the untreated group. Our study suggests that VNP has high potential in therapeutic angiogenesis.
