Abstract
Hyper-branched PG6-PLA polymers based on hydrophilic hyperbranched polyglycerol (PG6) and the ester chain poly(l-lactide) (PLA) were synthesized and facilitated to develop a novel biocompatible release-controlled gene vector. The hyper-branched structure of PG6-PLA was verified by NMR, FT-IR and SEC-MALLS analysis. The co-assembly of PG6-PLA with high molecular weight polyethylenimine (PEI) of 25 kDa was discussed. The results of TEM, fluorescence tracking and size/zeta-potential analysis revealed that the PG6-PLA/PEI25k/DNA could co-assemble to generate a novel fiber core-shell conformation. In vitro cell experiment demonstrated that PG6-PLA significantly enhanced the ability of PEI25k to remain within cells and mediate luciferase and EGFP expression in the human embryonic kidney cell line 293T and human cervical carcinoma cell line HeLa, which was accompanied by improved cell biocompatibility and an extended period of transgene expression. Importantly, the binary vector PG6-PLA/PEI25k exhibited specific affinity to some tumour cell lines including HeLa and the HepG2 human hepatoma cell line. These results suggested that the novel gene delivery system based on fiber core-shell PG6-PLA/PEI25k/DNA can serve as a gene delivery system to mediate more efficient transgene expression.

Abstract
Cystic fibrosis (CF) is the most common autosomal lethal recessive disorder in the Caucasian population. The major cause of mortality is lung disease, owing to the failure of a functional protein from the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Today, even though the knowledge about the CFTR genomic is extensive, no efficient treatment has been developed yet. In this context, gene therapy represents a potential important advance on condition that it could develop efficient and safe transfection agents. Even though viral vectors have been used in most clinical trials owing to their high transfection efficiency, random integration and immunogenicity are still critical side effects. Consequently, all of these drawbacks brought forth the development of nonviral transfection systems. Although they engender few toxicity and immunogenicity problems, their low transfection efficiency is a hurdle that must be overcome. Over the past decade, we have developed an original family of monocationic lipids, cationic phosphonolipids, whose efficiency has been previously demonstrated both in vitro and in vivo. In this report, we observe that a new cationic phosphonolipid (KLN 30) can lead to the restoration of the CFTR protein following the ex vivo transfection of epithelial cells issuing from a F508 homozygous patient. The transgene expression and the cytotoxicity correlate with the charge ratio of the lipoplex. A kinetic study was performed, and a luminescent signal was detected until 35 d after transfection.

Abstract
The safe and efficient delivery of nucleic acids into haematopoietic stem cells (HSCs) has a wide range of therapeutic applications. Although viruses are being used in most clinical trials owing to their high transfection efficacy, recent results highlight many concerns about their use. Synthetic transfection reagents, in contrast, have the advantage of being safe and easy to manage while their low transfection efficiency remains a hurdle that needs to be addressed before they can be widely used. Using information on transfection mechanisms, a new family of monocationic lipids called lipophosphoramides was synthesized. Their efficiency to transfer genes into haematopoietic cell lines (K562, Jurkat and Daudi) and CD34+ cells was assessed. In this study, we report that one of these new compounds, KLN-5, leads to more efficient transfection activity than one of our previously most efficient reagents (EG-308) and the commercially available monocationic lipids (DC-CHOL and DOTAP/DOPE) (P<0.05). In addition, only a slight toxicity related to the chemical structure of the new compounds is observed. Moreover, we show that KLN-5 can successfully carry the transgene into haematopoietic progenitor cells (CD34+). These results demonstrate that synthetic transfection reagents represent a viable alternative to viruses and could have potential practical utility in a number of applications.
