Introduction: Cancer has become a major public health problem worldwide, with breast cancer is the most common cancer among women and one of the most important causes of death among them. Management of breast cancer have some adverse effects, with many factorx=s shiouln be considered to ordered the therapy. Use of chemotherapy will suppress cell proliferation and trigger apoptosis, but it cannot just focus on cancer cells only, but also would affected on other cells and cause. Objective: This study aim to analyze the inhibition effect of the Annonanceous sp. ethanolic extract to Vascular Endothelial Growth Factor (VEGF) on MCF-7 cells line Material and Methods: This study is an analytic experimental study used Randomized Complete Block Design (RCBD) with three repetitions. The extract was dissolved in 1 ml of DMSO with a concentration of 0.1%. Furthermore, dilution was made with a dose of 0 µg / ml (K); 25 µg / ml (P1); 50 µg / ml (P2); 100 µg / ml (P3); 200 µg / ml (P4). MCF-7 cells line were cultured used RPMI 1640 Medium with 80 – 90% confluent. The ethanolic extract of Annonaceous sp. were exposed to MCF-7 cells for 48 hours. Analyze of VEGF level use ELISA Methods with λ=405 nm. Results: The results of ELISA analyze shows that the ethanolic extract of Annonaceous sp. have potential effect to decreased of VEGF expression on sample with treatment on some concentration (p< 0,05). Conclusion: The ethanolic extract of Annonaceous sp. has shows the potential effect to decreased of VEGF level on MCF-7 cells line

e20566 Background: It is suggested that vascular endothelial growth factor (VEGF) induces neurogenesis in the brain and provides neuroprotectiveeffects. This study was designed to examine the relation between plasma VEGF level and cognitive functioning in breast cancer patients who have received chemotherapy. Methods: Early-stage breast cancer patients (stage I to III) who received anthracycline- and/or taxane-based chemotherapy were prospectively recruited at a single center. Perceived cognitive functioning (FACT-Cog) and computerized neuropsychological assessment (Headminder) were used to evaluate patients’ cognitive function at three time points: prior to chemotherapy (T1), at midpoint (T2), and end of chemotherapy (T3). Headminder evaluated four cognitive domains: Attention, Memory, Processing, and Response speed. Impairment in each domain were defined as a >2.5 reduction of the Z score from baseline, as calculated by the reliable change index for repeated cognitive measurements. Plasma VEGF levels were analyzed at each time point using the multiplex immunoassay. Spearman Correlation (rs) was utilized to correlate the change in plasma VEGF and neurocognitive functioning. Results: Thirty-six patients were recruited (median age: 51.5; Chinese: 80.6%; post-menopausal: 58.3%). Median plasma VEGF levels were T1: 19.2 pg/ml; T2: 26.5 pg/ml; T3: 21.9 pg/ml. Weak correlations were observed between the change in VEGF level and the change in FACT-Cog and Headminder scores for individual cognitive domain (Table). Conclusions: Results suggest a weak correlation between plasma VEGF level and cognitive functioning in the domains of attention, concentration, functional interferences, mental acuity and response speed. Larger sample size and longer follow up are required to further explore the findings. [Table: see text]

Environmental chemicals may affect human health by disrupting endocrine function. Their possible role in the mammary gland and breast tumors is still unknown. Previous studies have demonstrated that vascular endothelial growth factor (VEGF), a key factor in angiogenesis and tumor progression, is an estrogen-regulated gene. We analyzed whether VEGF expression is regulated by different xenoestrogens in several breast cancer cells, MELN (derived from MCF-7) and MELP (derived from MDA-MB-231) and stably expressing estrogen receptor α (ERα); these cell lines stably express estrogen response element (β-globin)-luciferase. Genistein, bisphenol A (BPA), 4-(tert-octyl)phenol (OP), dieldrin, and several phthalates, including benzyl butyl phthalate (BBP) and di-ethyl-2-hexyle phthalate (DEHP), were first shown to be estrogenic. These compounds induced a dose-dependent increase of VEGF secretion in MELN and MCF-7 cells; maximal effect was observed at 1–10 μM non-cytotoxic concentrations and was inhibited by the antiestrogen ICI 182 780. VEGF increase was not observed in ERα-negative MDA-MB-231 cells. Most substances increased VEGF transcript levels in MELN cells. In contrast, γ-hexachlorocyclohexane, vinclozolin, and the phthalates (mono-n-butyl ester phthalic acid, di-isononyle phthalate, and di-isodecyle phthalate) were ineffective on both VEGF secretion and estrogenic luciferase induction in these cell lines. Specific kinase inhibitors PD98059, SB203580, or LY294002 suppressed the xenoestrogen-induced VEGF response, suggesting activation of MEK, p38 kinase, and phosphatidylinositol-3-kinase pathways. Our in vitro results show for the first time that genistein and xenoestrogens (BPA, OP, dieldrin, BBP, and DEHP at high concentrations) up-regulate VEGF expression in MELN cells by an ER-dependent mechanism. Since VEGF increases capillary permeability and breast tumor angiogenesis in vivo, the physiological relevance of these findings is discussed.
