The aim of the present study was to test the ability of the chemotherapeutic agent suramin to inhibit angiogenesis in experimental models in vitro and in vivo. In the culture of rat aortic rings on fibronectin, suramin dose-dependently inhibited vascular cell growth, achieving the maximal effect (mean − 88% versus controls, P < 0.05) at 400 μg/ml. Image analysis showed that suramin could inhibit microvessel sprouting in fibrin from rat aortic rings as evaluated by the ratio between the cellular area and the mean gray value of the sample (sprouting index); suramin at 50 μg/ml significantly reduced the sprouting index from the control value of 0.35 ± 0.04 to 0.14 ± 0.02 mm2/gray level (P < 0.05). Likewise, the area occupied by cells was 19.2 ± 1.8 mm2 as compared with 41.8 ± 4.2 mm2 in controls (P < 0.05). In the rat model of neovascularization induced in the cornea by chemical injury, suramin at 1.6 mg/eye per day reduced the length of blood vessels (0.7 ± 0.1 mm as compared with 1.5 ± 0.1 mm in controls, P < 0.05). In the same model the ratio between the area of blood vessels and the total area of the cornea (area fraction score) was decreased by suramin from 0.19 ± 0.02 in controls to 0.03 ± 0.003 (P < 0.05). Suramin given i.p. at 30 mg/kg per day markedly inhibited the neovascularization induced in the rat mesentery by compound 48/80 or conditioned medium from cells secreting the angiogenic protein fibroblast growth factor-3 (FGF-3). The area fraction score in control rats treated with compound 48/80 was 0.31 ± 0.03, and this was reduced to 0.07 ± 0.01 by suramin (P < 0.05). After i.p. administration of FGF-3 the area fraction score was reduced by suramin from 0.29 ± 0.03 to 0.05 ± 0.01 (P < 0.05). These results provide evidence that suramin exerts inhibitory effects on angiogenesis in both in vitro and in vivo models. Received: 9 January 1998 / Accepted: 29 June 1998  相似文献

Aims  We evaluated both in vitro and in vivo antitumoral properties of an isolated compound from Wilbrandia ebracteata, dihydrocucurbitacin-B (DHCB), using B16F10 cells (murine melanoma). Materials and methods  We made use of MTT and 3H-Thymidine assays to investigate the cell viability and cell proliferation, flow cytometry analysis to monitor cell cycle and apoptosis, western blot analysis to evaluate the expression of cell cycle proteins, imunofluorescence analysis and in vivo tumor growth and metastasis. Results  Dihydrocucurbitacin-B significantly reduced cell proliferation without important effects on cells viability. DHCB lead cells to accumulate in G2/M phases accompanied by the appearance of polyploid cells, confirmed by fluorescence assays that demonstrated a remarkable alteration in the cell cytoskeleton and formation of binuclear cells. Annexin-V-FITC incorporation demonstrated that DHCB did not induce apoptosis. About 10 μg/mL DHCB was found to decrease cyclin-A, and especially in cyclin-B1. The in vivo experiments showed that DHCB treatment (once a day up to 12 days; p.o.) was able to reduce the tumor growth and lung metastasis up to 83.5 and 50.3%, respectively. Conclusions  Dihydrocucurbitacin-B reduces cell proliferation due to a decrease in the expression of cyclins, mainly cyclin-B1 and disruption of the actin cytoskeleton, arresting B16F10 cells in G2/M phase. Taken together, the in vitro and in vivo experiments suggest that DHCB was effective against cancer, however, it remains to be proved if DHCB will be a good candidate for drug development.  相似文献

We studied the influence of surgical trauma to the iliac bone on the implantation of I. V. injected tumor cells, which formed tumor in the surgical wounds of 27/84 mice (32%). None of these mice or nonsurgical mice developed tumor in the opposite or uninjured pelvic bone (P < 0.0001). When different numbers (105, 5 × 105, and 10 × 105) of TA3Ha cells were injected I. V. immediately after surgery, the frequency of tumor formation showed an increase (respectively, 32%, 63%, 71%). As the interval between induction of trauma and tumor cell injection was increased from 0 to 15 days, the frequency of tumor formation declined from 32% to 0%. These results suggest that the healing wound is a privileged site for experimental metastasis, particularly in the early stages. It is likely that the proteins in the blood clotting cascade are involved in local tumor implantation. © 1994 Wiley-Liss, Inc.  相似文献

Objective The aim of this study was to investigate the changes in dietary preferences in cancer patients in China and to determine the need for encouraging the adherence to a sensible diet among such patients.Methods A total of 468 cancer patients were interviewed using a self-designed questionnaire focusing on changes in the intake of specific foods. Data were analyzed using SPSS 16.0. Results Most patients completely avoided roosters and carp(73.1%), condiments(51.9%), and meat of aquatic species(40.4%). All other types of the specific foods were completely avoided by different subpopulations of the patients.Conclusion In addition to focusing on disease treatment, medical professionals need to help cancer patients overcome barriers associated with the customs of avoiding specific foods encompassed by the term ”fawu” and provide them with dietary guidance in order to prevent negative nutritional effects.  相似文献

FDG-PET has boomed in recent years for diagnosis, staging and the search for recurrence of a large number of tumors. This is particularly true for soft tissue sarcomas and musculoskeletal sarcomas, for which the first publications on the potential role of FDG-PET dating back to the early 1990s. The majority of published studies on adult sarcomas confer, possibly a mixed population. Studies dedicated to pediatrics population are much rarer. The "Standards, Options and Recommendations" of the French Federation of Anticancer Centers published in 2003 on "The use of FDG-PET in oncology" and make recommendations and expert advices as part sarcomas of adult patients. After a first part dedicated to the particular interpretation of FDG PET in children, the purpose of this paper is to review the potential contribution of this exam in the treatment of pediatric sarcomas.  相似文献
