Pharmacological inhibition of VEGF-A has proven to be effective in inhibiting angiogenesis and vascular leak associated with cancers and various eye diseases. However, little information is currently available on the binding kinetics and relative biological activity of various VEGF inhibitors. Therefore, we have evaluated the binding kinetics of two(More)
Environmental enrichment (EE), where animals are exposed to a complex novel environment, has been shown to induce synaptic plasticity in both intact and injured animals. The purpose of this study was to investigate the effects of EE on spatial memory and structural modifications of synaptic junctions in rats following transient focal cerebral ischemia.(More)
Bisphenol-A (BPA) is one of the most common environmental endocrine disrupters with mixed estrogen agonist/antagonist properties. The toxicity of BPA has been extensively evaluated in a variety of tests in rodents, including developmental and reproductive toxicity, and carcinogenicity. The objective of the present study is to evaluate whether or not(More)
Bisphenol-A (BPA), an environmental endocrine disruptor, has been reported to possess weak estrogenic, anti-estrogenic, and anti-androgen properties. Previous evidence indicates that perinatal exposure to low levels of BPA affects anxiety-like and cognitive behaviors in adult rodents. The present study aims to investigate the effect of BPA on emotional(More)
Our previous study indicated that perinatal exposure to low-dose BPA, one of the most common environmental endocrine disrupters, alters behavioral development in offspring mice. Given that synaptic structure of the hippocampus is closely related to behaviors, in the present study, we examined the effects of perinatal exposure to BPA (0.04, 0.4, and 4.0 mg(More)
Humans are routinely exposed to low levels of bisphenol A (BPA), a synthetic xenoestrogen widely used in the production of polycarbonate plastics. The effects of long-term exposure to BPA on memory and modification of synaptic structure in hippocampus of adult mice were investigated in the present study. The adult mice were exposed to BPA (0.4, 4, and 40(More)
In the present study, the protective effects of puerarin (Pur) on learning and memory in ovariectomized mice were investigated. One week after ovariectomy (Ovx) or sham operation, female mice were given a 4-week treatment of Pur (50 or 100 mg/kg,i.p.) or estradiol benzoate (EB, I or 5 pg/day, i.p.). The results showed that, following treatment with 50 or(More)
Angiopoietin2 (Ang2) and its Tie2 receptor have extensive effects on tumor malignancy including angiogenesis and metastasis. In this study, we evaluated the protective effect of Ang2 on doxorubicin-induced apoptosis in HepG2 cells. Ang2 (400 ng/ml) attenuated doxorubicin-mediated cytotoxicity by upregulating the expression of Survivin and Ref-1, which was(More)
To explore the possible mechanism of perfluorooctane sulfonates (PFOS's) reproductive toxicity, mouse Leydig cells cultured in vitro were exposed to a serial concentration of PFOS for four more days of culture. Apoptosis during the process was checked. After 24 h, apoptosis occurred to all of the groups ≥ 50 μg/mL PFOS. After 72 h, 37.5 μg/mL dose also(More)
To study the function and potential application of nkx2.5, a critical gene for heart development, we constructed a recombinant adenovirus overexpressing nkx2.5 gene (Ad-Nkx2.5) with the AdEasy system. To evaluate the effect and mechanism of Ad-Nkx2.5 against oxidative injury, the H9c2 myocardial cells were infected with the recombinant adenoviruses(More)
