Abstract
Objectives: We aimed to investigate the distribution of immunoreactivities of vascular endothelial growth factor(VEGF), endothelial nitric oxide synthase (eNOS), and inducible NOS (iNOS) on breast cancer cells in response to treatment with boron derivatives.Methods: We initially analyzed the cytotoxic effect and IC50 value of boron by MTT assay. For the evaluation of theangiogenesis, expression level of antibodies was detected to following boron derivatives such as boric acid, boronpenta (BP), and T-Boron (DPD) in the absence of boron treatment using the indirect immunohistochemical method. Theevaluation of these staining was done using the H-scoring system.Results: It was found that immunoreactivities of VEGF, eNOS, and iNOS increased on control compared to those of thecells of MDA-MB231 human breast cancer cell line. Following boron derivatives treatment, it was observed that theywere inhibited the VEGF/NOS labeling in MDA-MB-231 breast cancer cells.Conclusion: The present data suggest that BP, especially DPD, inhibits the angiogenesis of breast cancer cells throughVEGF pathway. From this point, these boron derivatives may provide a novel therapeutic approach for breast cancertreatment.
