Effects of antisense oligonucleotides targeting VEGF on radio sensitivity of uterine cervix cancer Hela cells

引用

The Chinese-German Journal of Clinical Oncology 2009年第1期8卷 50-54页

作者： Li＇na Xing Li Qi Department of Radiotherapy The 2nd Affiliated Hospital Harbin Medical University Harbin 150086 China

Objective： To determine the impact of antisense oligonucleotides targeting vascular endothelial growth factor （VEGF） on radiosensitivity of uterine cervix cancer Hela cells. Methods： VEGF antisense oligodeoxynucleotides （ASODN） was transfected into Hela cells by liposome-mediated method. Cells transfected with the oligodeoxynuclecotide and saline were used as control groups. Cells were irradiated by 6 MV X ray at the dose of 0 Gy, 2 Gy, 4 Gy and 6 Gy respectively. The expression of VEGF mRNA was determined by RT-PCR. Apoptosis were evaluated using FCM. Cloning efficiency was determined by colony formation assay. Results： The expression of VEGF mRNAwas inhibited by ASODN （P 〈 0.01） in Hela cells. The inhibited activation which was influenced by radiation resulted in increasing apoptosis （P 〈 0.01） and inhibiting plating efficiency （P 〈 0.01）. Conclusion： The expression of VEGF induced by X irradiation in Hela cells can be blocked by VEGF ASODN. Treatment with VEGF might increase apoptosis in HeLa cells and enhance radiosensitivity.

Analysis of Prognosis and Prognostic Factors of Cervical Adenocarcinoma and Adenosqumous Carcinoma of the cervix

Chinese Journal of Clinical Oncology 2009年第2期6卷 133-137页

作者： Guangwen Yuan Lingying Wu Xiaoguang Li Manni Huang Department of Gynecologic Oncology Cancer Hospital Chinese Academy of Medical Science & Peking Union Medical College Beijing 100021. China

OBJECTIVE To analyze clinical characteristics and treatment methods of the patients with adenocarcinoma of the uterine cervix （AUC） and adenosquamous carcinoma of the cervix （ASCC）. To compare the survival time of the patients in 2 groups and analyze the prognostic factors. METHODS Clinical data of both 123 patients with AUC and 32 patients with ASCC treated at the cancer Hospital, Chinese Academy of Medical Science （CAMS）＆ Peking Union Medical College （PUMC）, were retrospectively analyzed. RESULTS The median age of the AUC patients was 50 years, and that of the ASCC patients was 44, P = 0.019. Poorly-differentiated （grade 3） cases accounted for 59.5% of the total ASCC patients, while only 32.5% of the AUC patients were in grade 3, P = 0.002. In 123 AUC patients, relapse or failure of the treatment occurred in 63 of the patients （51.2%）, and the median relapse time was 6 months （0-59 months）. In 32 ASCC patients, relapse or failure of the treatment occurred in 8 of these patients （51.2%）, with a median relapse time of 4.5 months （0-52 months）. The overall 5-year survival rate of the AUC patients was 49.8%, which was significantly lower than that of the ASCC patients （74.1%）, P = 0.015. The 5-year survival rates of the ASCC patients in Stage Ⅰ-Ⅲ were higher than that of the AUC patients with the same stages. However, statistical significant difference could only be found among the patients in Stage II, P = 0.006. The 5-year survival rates of the ASCC patients with various differential grade were higher than those of the AUC patients with the same differential grade, but statistical significant difference could only be found among the patients in the two groups with moderately differentiation, P = 0.039. It was found by Cox regression analysis that only clinical stage （P 〈 0.001） and histological type （P = 0.046） were the independent prognostic factors. CONCLUSION Clinical stage and histological type were the independent prognostic factors of the AUC and ASCC pat

Potential Anti-cancer Activity of Furanodiene

引用

Chinese Journal of cancer Research 2009年第2期21卷 154-158页

作者： Zhen-zhen Ba Yan-ping Zheng Hui Zhang Xiu-yan Sun Dong-hai Lin School of Pharmaceutical Science Yantai University Yantai 264005 China

Objective： To study the isolated from the essential oil VIVO anti-tumor activities of furanodiene of the rhizome of Curcuma wenyujin （C15H200）, a primary sesquiterpene compound YH Chen et C. Ling（Wen Ezhu）, in vitro and in Methods： In vitro MTT assay was used to further study the effects of time and dosage on anti-proliferation of furanodiene against the sensitive Hela, Hep-2, HL-60, U251 cells, based on the cytotoxic effects of furanodiene on 12 human malignant tumor cell lines with the essential oil of Wen Ezhn as control., and the half-inhibitory concentration （IC50） was observed. In vivo uterine cervix （U14） tumor cell was selected and the conventional assay method of anti-tumor activity was employed. Furanodiene liposome was administered intraperitoneally, and tumor-inhibitory rate, thymus and spleen indexes were observed. Results： The inhibitive effects on cell proliferation were shown in all of the twelve cell lines and the cytotoxic effects of furanodiene against Hela, Hep-2, HL-60, U251 cells were observed after 12 h of administration, the effect could last for at least 48 h in a dose dependent manner, and the IC50 values were 0.6, 1.7, 1.8, 7.0μg/ml, respectively. Furanodiene was also found to show inhibitive effects on the proliferation of uterine cervix （U14） tumor induced in mice. The tumor inhibition rates were 36.09% （40 mg/kg）, 41.55% （60 mg/kg）, 58.29% （80 mg/kg）, respectively. Conclusion： Furanodiene is one of primary anti-cancer active components in the essential oil of Wen Ezhu, and also a very effective agent against uterine cervix cancer, and has protection effect on the immune function.
