腺病毒介导的肿瘤血管靶向的体外自杀基因治疗研究

本工作在血管内皮细胞中分别建立了HSV-tk/GCV和EC-cd/5-FC自杀基因系统,用于抑制实体肿瘤中血管生成的研究.构建含自杀基因的重组腺病毒AdCMVtk和AdCMVcd,滴度均1×10~(12)pfu/ml.病毒感染小鼠血管内皮细胞lGll(MOI=100),并鉴定自杀基因的表达,测定原药对它们的杀伤.生长抑制试验表明,GCV对lGll/Ad-tk细胞杀伤的IG_(50)为0.2μmol/ L,5-FC对lGll/Ad-cd细胞杀伤的IC_(50)为20μmol/L.电镜下显示被原药杀伤的血管内皮细胞有明显的细胞凋亡现象.同时混合细胞实验证明两系统均存在明显的旁杀伤效应.从而在体外水平证明了HSV-tk/GCV和EC-cd/5-FC自杀基因系统杀伤增生血管内皮细胞的有效性.

Hybrid BiOBr/UiO-66-NH2 composite with enhanced visible-light driven photocatalytic activity toward RhB dye degradation

Metal–organic framework (MOFs) based composites have received more research interest for photocatalytic applications during recent years. In this work, a highly active, visible light photocatalyst BiOBr/UiO-66-NH₂ hybrid composite was successfully prepared by introducing various amounts of UiO-66-NH₂ with BiOBr through a co-precipitation method. The composites were applied for the photocatalytic degradation of RhB (rhodamine B) dye. The developed BiOBr/UiO-66-NH₂ composites exhibited higher photocatalytic activity than the pristine material. In RhB degradation experiments the hybrid composite with 15 wt% of UiO-66-NH₂ shows degradation efficiency conversion of 83% within two hours under visible light irradiation. The high photodegradation efficiency of BUN-15 could be ascribed to efficient interfacial charge transfer at the heterojunction and the synergistic effect between BiOBr/UiO-66-NH₂. In addition, an active species trapping experiment confirmed that photo-generated hole⁺ and O₂⁻ radicals are the major species involved in RhB degradation under visible light.

Neonatal gene transfer with a retroviral vector results in tolerance to human factor IX in mice and dogs

The effect of neonatal gene transfer on antibody formation was determined using a retroviral vector (RV) expressing human factor IX (hFIX). Normal mice from different strains injected intravenously with RV as newborns achieved therapeutic levels of hFIX without antibody production and were tolerant as adults to challenge with hFIX. Neonatal hemophilia B mice that received different amounts of RV achieved stable and dose-related expression of hFIX without anti-hFIX antibody formation. After protein challenge, antibody formation was markedly reduced for animals that expressed hFIX at levels higher than 14 ng/mL (0.3% of normal). However, antibodies developed for animals that received the lowest dose of RV and expressed hFIX at approximately 2 ng/mL before protein challenge. In dogs, neonatal injection of a high dose of RV resulted in 500 ng/mL hFIX in plasma without antibody formation. We conclude that neonatal gene transfer with RV does not induce antibody responses to hFIX in mice or dogs and that mice achieving levels greater than 3 x 10-10 M hFIX are usually tolerant to protein injection as adults. Low-dose gene therapy or frequent protein injections in the neonatal period might induce tolerance to subsequent injections of protein with a low risk for adverse effects.
