3.Progress on tumor angiogenesis and gene therapy for antiangiogenesis
Journal of Medical Postgraduates 2003;0(06):-
Tumor angiogenesis, resulting from the imbalance of angiogenic cytokines and angiogenesis inhibitors, is crucial for tumor growth and metastasis. As a new field of cancer therapy, tumor anti-angiogenesis therapy with regard to abrogation of tumor vasculature has become an important anti-tumor strategy. Gene therapies have the potential to provide antiangiogenic mediators specifically targeted to organs containing tumors and make a great improvement in this therapy. This article reviews the current understanding of tumor angiogenesis, with a focus on gene therapy in this field.

Objective The aim of this study was to analyze the influence of combined therapy with L-carnitine and erythropoietin on renal anemia and nutritional status in patients treated with maintenance hemodialysis.Methods The combination of computer and manual searches were used.A Meta analysis was made regarding the effect of combined therapy with L-carnitine and erythropoietin on the improvement of renal anemia and nutritional status in patients treated with maintenance hemodialysis.The quality of the 9 studies was evaluated with the Jadad score.Statistical analysis was carried out by RevMan 5.0.Results A total of 428 patients in 9 reports were analyzed.Metaanalysis showed that there were significant improvement in hemoglobin (Hb) [WMD =9.21,95% CI (7.69 ~10.73)] and hematocrit (Hct) [WMD =2.61,95% CI (2.28 ~ 2.93)],albumin (ALB) [WMD =1.64,95% CI (1.04 ~ 2.24)] and total protein (TP) [WMD =2.72,95 % CI (0.67 ~ 4.77)] in the treatment group compared with the control group.The level of erythropoietin dosage [WMD =-38.24,95% CI (-76.87 ~ 0.39)] was decreased significantly.But there were no significant differences in triglyceride and serum phosphorus.Conclusion Combined therapy with L-carnitine and erythropoietin in patients treated with maintenance hemodialysis leads to significant improvement of renal anemia and nutritional status.

Malignant transformation is closely related to gene mutations.The tumor suppressor gene p53 codes for a transcription factor,P53 protein,plays a critical regulation role in oncogene expression,DNA synthesis and repair systems,and cell apoptosis.It has been demonstrated that p53 mutation occurs in more than 50% of cancer cells,which is thought to play a crucial role in malignant transformation.p53-based gene therapeutical approaches in vitro and in vivo aiming at a direct correction of the specific molecular defect in p53-mutated malignant cells,showed notable efficacy in numerous cancer types.In this review,we discussed the current advances in this field,focusing on adenovirus-mediated wild-type p53 gene therapy.

Objective To express the recombinant human canstatin protein, and to examine its biological activity. Methods Canstatin cDNA was cut off from the plasmid pUCm-T/canstatin with restriction enzymes BamHⅠ and Hind Ⅲ. The cDNA fragment was then ligated into the correspondence sites of plasmid pET-22b(+) by T4 DNA ligation enzyme and transformed into E.coli BL21 which was induced to express proteins with isopropyl-1-thio-b-dgalactopyranoside (IPTG). The expressed proteins were analyzed by SDS-PAGE and purified through Ni-NTA column affinity chromatography. Chick chorioallantoic membrane (CAM) assay was performed to determine the activity of the recombinant protein. Results Canstatin cDNA from pUCm-T showed one clear objective DNA band with electrophoresis. Seven of positive colonies were selected and identified by restriction enzyme analysis with BamH Ⅰ and Hind Ⅲ. Electrophoresis revealed that all selected colonies had two specific bands,one near the location of primary plamid,the other near that of objective gene fragment. After IPTG induction, there was a new protein band about 24 000 on SDS-PAGE.The induced product over total bacterial proteins in 1,2, 3. and 4 hours after induction was 18. 2%, 18. 8%, 23.0% and 23.4%, respectively, by densitometry examination. CAM assay demonstrated that the recombinant canstatin protein significantly inhibited the embryonic neovascularization in a dose-dependent manner. Conclusion The prokaryotic expression vector of human canstatin gene has been successfully constructed, laying the foundation for further clinical study.
