PURPOSE The present study was designed to elucidate the fluctuation of activated CECs (aCECs) during different therapies and to investigate their predictive value for efficacy of anti-angiogenesis and chemotherapy in advanced non-small cell lung cancer (NSCLC). METHODS Seventy-two patients were randomized into three arms, treated with concomitant NP(More)
OBJECTIVE To observe and analyze the antitumor effect of endostar combined with docetaxel under different administration sequences. METHODS Nude mice with xenograft tumor (A549 cell line) were randomized into 3 groups, 8 mice/group: (1) Concurrent administration group (each mouse: endostar 400 µg/d, d1-d35, docetaxel 10 mg/kg, every 3 days, d1-d19); (2)(More)
BACKGROUND Although antiangiogenesis therapy plays an important role in anti-neoplastic treatment with its recognized efficacy and slight adverse effect, there is no prospective clinical trial to define ideal markers for predicting efficacy of antiangiogenic therapy. This study was undertaken to investigate the changes of activated circulating endothelial(More)
OBJECTIVE To investigate the changes and clinical value of circulating endothelial cells (CEC) in the peripheral blood of advanced NSCLC patient. METHODS Sixty-seven advanced NSCLC patients were randomly divided into either the treatment group with NP plus endostatin or control group with NP alone. Level of CEC and cytokeratin (CK) in the peripheral blood(More)
OBJECTIVE To compare the effect of rh-endostatin on micrangium in tumor and myocardial tissue in nude mice. METHODS Nude mice were randomized into 4 groups (10 mice in each group), blank control group (without tumor burden, received NS 100 µl×d(-1) injection), drug control group (without tumor burden, received rh-endostatin 400 µg×d(-1) injection), model(More)
OBJECTIVE To assess the effect of endostatin on growth and neoplastic angiogenesis in transplanted human lung adenocarcinoma Calu-6 tumor in nude mice. METHODS To treat Calu-6 tumor-bearing mice with endostatin at different doses, and to record the changes of the tumor size. The expressions of survivin, VEGF, COX-2 and MVD in tumor tissue were examined by(More)
BACKGROUND & OBJECTIVE Beta protein 1 (BP1) gene, a novel member of DLX homeobox gene family, is located in 17q21-22 region and overexpressed in both acute myeloid leukemia and acute T cell lymphocytic leukemia. However, the reports on the function of BP1 in solid tumors are rare. The study was designed to determine the expression of BP1 gene in breast(More)
BACKGROUND & OBJECTIVE Multidrug resistance of tumor cells often leads to failure of chemotherapy. The over-expression of P-glycoprotein (P-gp), encoded by multidrug resistance 1 (mdr1) gene, plays an important role in multidrug resistance of breast cancer. This study was to explore the feasibility of silencing mdr1 gene by small interfering RNA (siRNA) in(More)
OBJECTIVE In order to explore the correlation between the centrosome aberration and oncogenesis of the breast carcinoma, the expression of alpha-tubulin and gamma-tubulin proteins in breast precancerous lesions, ductal carcinoma in situ (DCIS) and invasive ductal carcinomas (IDC) was investigated. METHODS Quantitative immunofluorescence analysis was(More)
