Fibrinogen, bFGF and VEGF levels during antibiotic therapy in gynecologic cancer: a preliminary report.
The role of angiogenesis in the development of neoplasia has been identified and characterized. However, antiangiogenic therapeutic intervention still requires more evidence to become recognized and successful. The aim of this study was to evaluate levels of selected proangiogenic factors, such as fibrinogen, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in serum of patients with the gynecologic cancer on the first, third and sixth day of antibiotic therapy, routinely administered as a perioperative treatment. In addition, serum concentrations of gamma-gamma dimers and alpha-polymers of cross-linked fibrin structure and the degree of bFGF binding with the fibrin network were investigated. Immunohistochemistry staining of the excised tumor tissue was also performed. We observed higher levels of bFGF, VEGF, as well as fibrinogen in patients with gynecologic malignancy, as compared to healthy women. In cancer patients, the concentration of alpha-polymers and gamma-gamma dimers of fibrin network increased. Further only gamma-gamma dimers fraction of fibrin was found to bind to bFGF. Immunohistochemical analysis indicated the presence of bFGF in an excised tumor tissue. In conclusion, the decrease of proangiogenic bFGF and fibrinogen levels in a clinical trial of gynecologic patients may confirm anti-angiogenic properties of selected antibiotic therapy.
期刊介绍：
Started in 1964, this journal publishes original research articles in the following areas: structure-function relationships of biomolecules; biomolecular recognition, protein-protein and protein-DNA interactions; gene-cloning, genetic engineering, genome analysis, gene targeting, gene expression, vectors, gene therapy; drug targeting, drug design; molecular basis of genetic diseases; conformational studies, computer simulation, novel DNA structures and their biological implications, protein folding; enzymes structure, catalytic mechanisms, regulation; membrane biochemistry, transport, ion channels, signal transduction, cell-cell communication, glycobiology; receptors, antigen-antibody binding, neurochemistry, ageing, apoptosis, cell cycle control; hormones, growth factors; oncogenes, host-virus interactions, viral assembly and structure; intermediary metabolism, molecular basis of disease processes, vitamins, coenzymes, carrier proteins, toxicology; plant and microbial biochemistry; surface forces, micelles and microemulsions, colloids, electrical phenomena, etc. in biological systems. Solicited peer reviewed articles on contemporary Themes and Methods in Biochemistry and Biophysics form an important feature of IJBB.
Review articles on a current topic in the above fields are also considered. They must dwell more on research work done during the last couple of years in the field and authors should integrate their own work with that of others with acumen and authenticity, mere compilation of references by a third party is discouraged. While IJBB strongly promotes innovative novel research works for publication as full length papers, it also considers research data emanating from limited objectives, and extension of ongoing experimental works as ‘Notes’. IJBB follows “Double Blind Review process” where author names, affiliations and other correspondence details are removed to ensure fare evaluation. At the same time, reviewer names are not disclosed to authors.
