Wei LI PhD , Siming GUAN MM , Zifang SONG PhD , Qichang ZHENG PhD , Jun XIONG PhD , Dan SHANG PhD , Xiaogang SHU PhD ,

Frontiers of Medicine 2009, Volume 3, Issue 3,   Pages 297-302 doi: 10.1007/s11684-009-0058-x

Abstract: The eukaryotic expression vector of human arresten gene was constructed and its secretive expression human embryonic kidney (HEK 293) cells was detected. Human arresten gene was amplified from recombinant plasmid pGEM-Arr by polymerase chain reaction (PCR), and then digested with restriction endonucleases I and I. The target fragment was inserted into the I and I restriction sites of eukaryotic expression vector pSecTag2 to construct pST-AT. Restriction analysis and DNA sequencing indicated that the arresten gene was successfully inserted into pSecTag2. The recombinant plasmid was subsequently transfected into HEK 293 cells with LipofectAMINETM2000 Reagent, and the expression of the target gene was detected. RT-PCR revealed that the mRNA of the target gene was transcribed in the transfected HEK 293 cells. Western Blot analysis verified that the recombinant protein in supernatants was correct. The supernatants of transfected cells were prepared, and 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay was carried out to assess their effect on the proliferation of human umbilical vein endothelial cells, which showed that the recombinant protein could significantly suppress the proliferation of human umbilical vein endothelial cells . These results provided a solid foundation to explore the usage of arresten in tumor anti-angiogenic gene therapy.

The relationship between platelet-derived growth factor expression and angiogenesis/lymphangiogenesis

Guocheng LIU MD, Shouhua YANG MD, Zehua WANG MD,

Frontiers of Medicine 2009, Volume 3, Issue 4,   Pages 447-451 doi: 10.1007/s11684-009-0082-x

Abstract: This paper is aimed to examine if changes in platelet-derived growth factor (PDGF) expression at different stages of cervical cancer are related to the variation in blood vessel density (BVD) and lymphatic vessel density (LVD) to evaluate the relationship between PDGF expression and stages and metastasis of cervical cancer. Polymerase chain reaction (PCR) and RT-PCR were used to detect the expression levels of PDGF in 45 cervical cancer tissue samples (the experimental group). The samples were immunohistochemically stained with monoclonal antibodies D2-40 and CD34, and BVD and LVD were measured. The expressions of PDGF-A, -B, and- D were all higher in the experimental group than in the control group (<0.05); no significant difference was found in the expression of PDGF-C between the experimental group and the control group (>0.05). PDGF-A and -B expression was positively related with BVD and LVD (<0.01, R= 0.49, 0.527, 0.327, 0.68). The expression levels of PDGF-C and -D were not significantly related with BVD and LVD. At the early stage of cervical cancer, BVD and LVD were significantly higher than in the controls (<0.01). The BVD and LVD in tissues in the surrounding areas of cervical cancer were significantly higher than in tissues at cancer center, and LVD was related to lymph node metastasis (<0.001). BVD and LVD were not associated with the differentiation and pathological stages of cervical cancer. The expressions of PDGF-A, -B, and -D in cervical cancer were closely related with the clinical stages of cervical cancer. PDGF-A and -B were intimately associated with the lymph node metastasis and prognosis of cervical cancer.

Hypoxia-induced activity loss of a photo-responsive microtubule inhibitor azobenzene combretastatin A4

Yang An, Chao Chen, Jundong Zhu, Pankaj Dwivedi, Yanjun Zhao, Zheng Wang

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 5,   Pages 880-888 doi: 10.1007/s11705-019-1864-6

Abstract: The conformation-dependent activity of azobenzene combretastatin A4 (Azo-CA4) provides a unique approach to reduce the side-effects of chemotherapy, due to the light-triggered conformation transition of its azobenzene moiety. Under hypoxic tumor microenvironment, however, the high expression of azoreductase can reduce azobenzene to aniline. It was postulated that the Azo-CA4 might be degraded under hypoxia, resulting in the decrease of its anti-tumor activity. The aim of this study was to verify such hypothesis in HeLa cells . The quantitative drug concentration analysis shows the ratiometric formation of degradation end-products, confirming the bioreduction of Azo-CA4. The tubulin staining study indicates that Azo-CA4 loses the potency of switching off microtubule dynamics under hypoxia. Furthermore, the cell cycle analysis shows that the ability of Azo-CA4 to induce mitotic arrest is lost at low oxygen content. Therefore, the cytotoxicity of Azo-CA4 is compromised under hypoxia. In contrast, combretastatin A4 as a positive control maintains the potency to inhibit tubulin polymerization and break down the nuclei irrespective of light irradiation and oxygen level. This work highlights the influence of hypoxic tumor microenvironment on the anti-tumor potency of Azo-CA4, which should be considered during the early stage of designing translational Azo-CA4 delivery systems.
