Objective: To construct a recombinant adeno-associated virus (AAV) vector harboring human hypoxia inducible factor-1α (HIF-1α) gene and to express it in primarily cultured neurons in the hippocampus. Methods: Human HIF-1α gene was inserted into AAV vector plasmid pSNAV 2.0 to generate a recombinant plasmid pSNAV-HIF-1α, then pSNAV-HIF-1α was transfected into BHK-21 cells and selected by G418. The construction of rAAV-HIF-1α was achieved by infecting G418-resistant BHK-21 cells with recombinant herpes simplex virus. The recombinant rAAV-HIF-1α was confirmed by polymerase chain reaction(PCR). The titer of rAAV-HIF-1α was detected by dot-blot with digoxin labelled cytomegalovirus probe. The purity of rAAV-HIF-1α was detected by SDS-PAGE. The expression of HIF-1α protein was determined by Western blot. Results: PCR demonstrated that human HIF-1α gene was successfully inserted into rAAV-HIF-1α. The Virus titer was 1 × 1012/ml and the virus purity exceeded 98%. Western nblot analysis demonstrated that rAAV-HIF1α infected hippocampal neurons expressed HIF-1α protein. Conclusion: rAAV-HIF-1α has been successfully constructed and it is capable of expressing HIF-1α in cultured hippocampal neurons.

BackgroundChondroitin sulfate(CS) is a highly viscous and elastic acid mucopolysaccharide extracted from animal soft tissues,with a wide range of biological activity for use in clinical ophthalmology.Interim preservation solution containing CS has a significant protective effect on corneal endothelial cells (CECs).However,the protective effect played by CS in long-term glycerol cryopreservation of CECs remains to be studied.Objective This study is mainly attempted to investigate the protective effect of CS on graft CECs after cryopreservation by glycerin,and to compare the preserving outcome with that of sodium hyaluronate (SH).MethodsOne hundred and four eyes of fifty-two female Wistar rats were divided into four groups randomly.The cornea grafts were evenly anointed on the surface of the endothelium by 3％ CS and 1％ SH,respectively,and then cryopreserved in glycerol in the 3％ CS group and 1％ SH group,and the corneas cryopreserved only in glycerin were assigned to the glycerin only group.The fresh corneas of matched rats were used as the normal control group.Ninety-six female SD rats were appointed as recipients to receive allogeneic penetrating keratoplasty (PKP) 2 months after the graft cryopreservation.The viability of CECs on the corneas cryopreserved for 20 days and grafts of 14 days following surgery was assessed using trypan blue & alizarin red stain.The ultrastructure of cryopreserved corneas was examined under a transmission electron microscope.The rejection index (RI) and graft survival time were evaluated by inflammatory scoring under the slit lamp 1 day after operation,and regular pathological examination was performed after 7,14 or 30 days.The expression of transforming growth factor-β1 ( TGF-β1 ) and intercellular adhesion molecule-1 ( ICAM-1 ) in corneas and grafts were detected by immunochemistry.ResultsCECs morphology was normal in fresh cornea in normal control group,presenting no blue stained cells after trypan blue staining.In the 3％ CS group,few blue-stained cells were seen:however,the number of blue-stained cells noticeably increased in the 1％ SH group and glycerin only group.The viability and density of CECs were significantly lower in the 1％ SH group and glycerin only group,compared with the 3％ CS group (P＜0.05).Edema of the endoplasmic reticulum,inflammatory infiltration and neovascularization were more severe in the 1％ SH group and glycerin only group than the 3％ CS group 14 days after PKP.Compared with the 1％ SH group and glycerin only group,the R1 of the 3％ CS group was significantly reduced and the CECs survival time was delayed after PKP ( P＜0.05 ).Immunochemistry revealed that the expression of TGF-β1 in grafts (A value)was up-regulated and that of ICAM-1 was down-regulated in the 3％ CS group,compared with the 1％ SH group and glycerin only group ( P＜0.05).ConclusionsThe combination of 3％ CS with glycerol to cryopreserve corneal donor can maintain the viability of CECs for a longer duration and improve the effectiveness of PKP.
