Genistein plays an important role in the prevention of atherosclerosis. However, the underlying mechanisms have not been fully investigated. In this study, human umbilical vein endothelial cells (HUVECs) were pretreated with genistein (10, 100, and 1000 nM) for 6 h and then exposed to ox-LDL (50 mg/L) for another 24 h. Results showed that ox-LDL induced the expressions of E-selectin, P-selectin, monocyte chemotactic protein-1, interleukin-8, vascular adhesion molecule-1, and intercellular adhesion molecule-1, which were counteracted by genistein...

Kallistatin, an endogenous protein, protects against vascular injury by inhibiting oxidative stress and inflammation in hypertensive rats and enhancing the mobility and function of endothelial progenitor cells (EPCs). We aimed to determine the role and mechanism of kallistatin in vascular senescence and aging using cultured EPCs, streptozotocin (STZ)-induced diabetic mice, and Caenorhabditis elegans (C. elegans). Human kallistatin significantly decreased TNF-α-induced cellular senescence in EPCs, as indicated by reduced senescence-associated β-galactosidase activity and plasminogen activator inhibitor-1 expression, and elevated telomerase activity...

Phenolic compounds represent a class of environmental chemicals with potential endocrine disrupting capabilities. We investigated longitudinal associations of childhood exposures to phenols, from both man-made and natural sources, and subsequent measures of adiposity among girls enrolled in The Breast Cancer and Environment Research Program, 2004-2007. Baseline (ages 6-8 years) urinary concentrations were obtained for creatinine and phenol metabolites: enterolactone, genistein, daidzein, benzophenone-3, bisphenol A, sum of parabens (methyl, ethyl, and propyl parabens), 2,5-dichlorophenol, and triclosan...

Plants reputed to have cancer-inhibiting potential and putative active components derived from those plants have emerged as an exciting new field in cancer study. Some of these compounds have cancer-inhibiting potential in different clinical staging levels, especially metastasis. A few of them which stabilize cell-cell adhesions are controversial topics. This review article introduces some effective herbal compounds that target E-cadherin/β-catenin protein complex. In this article, at first, we briefly review the structure and function of E-cadherin and β-catenin proteins, Wnt signaling pathway, and its target genes...

Genistein (GEN) is one of the isoflavones that has effect on male reproduction. However, the underlying mechanism remains unknown. miRNAs are a type of small non-coding RNAs that play important roles in spermatogenesis. We measured the GEN levels and miR-17-92 cluster expression in infertile subjects and found that miR-17-92 might be involved in GEN induced abnormal spermatogenesis. To clarify, we fed adult ICR mice with different doses of GEN (0, 0.5, 5, 50 and 250 mg/kg/day) for 35 days to study the underlying mechanism...

Aspergillus oryzae cytochrome P450 monooxygenase (CYP57B3) is capable of catalyzing hydroxylation of genistein to produce 3΄-hydroxygenistein. Because hydroxylated derivatives of genistein, including 3΄-hydroxygenistein, exhibit various pharmacological activities, CYP57B3 would potentially be useful as a biocatalyst in the pharmaceutical field. We therefore performed random mutagenesis of CYP57B3 to improve its catalytic activities for genistein. Random mutations were introduced by error-prone PCR into CYP57B3, resulting in construction of a library of mutants...

Normal and keloid fibroblasts were examined using X-band (9.3 GHz) electron paramagnetic resonance spectroscopy. The effect of genistein on the concentration of free radicals in both normal dermal and keloid fibroblasts after ultraviolet irradiation was investigated. The highest concentration of free radicals was seen in keloid fibroblasts, with normal fibroblasts containing a lower concentration. The concentration of free radicals in both normal and keloid fibroblasts was altered in a concentration-dependent manner by the presence of genistein...

Genistein, a dietary polyphenol primarily found in soy products, has beneficial effects on bone. However, the effect of genistein on inflammatory periodontal destruction has not been investigated in detail. We explored whether genistein protects against lipopolysaccharide (LPS)/ligature-induced periodontitis in mice. We also examined the effect of genistein on LPS-stimulated inflammatory and oxidative stress using RAW 264.7 macrophages and human gingival fibroblasts (hGFs). The results from μCT and histological analyses revealed that intraperitoneal injection of genistein (20 mg/kg body weight) daily for three weeks inhibited LPS-mediated alveolar bone loss and periodontal tissue degradation...

Early postnatal exposures to Bisphenol A (BPA) and genistein (GEN) have been reported to predispose for and against mammary cancer, respectively, in adult rats. Since the changes in cancer susceptibility occurs in the absence of the original chemical exposure, we have investigated the potential of epigenetics to account for these changes. DNA methylation studies reveal that prepubertal BPA exposure alters signaling pathways that contribute to carcinogenesis. Prepubertal exposure to GEN and BPA + GEN revealed pathways involved in maintenance of cellular function, indicating that the presence of GEN either reduces or counters some of the alterations caused by the carcinogenic properties of BPA...

Oxidative stress and aldose reductase activity have been implicated in the development of diabetic complications. In this study, the antioxidant and aldose reductase (AR) inhibitory effects of Maackia amurensis (MA) were investigated. The ethyl acetate fraction of the MA extract showed the highest inhibitory activity in antioxidant and rat lens AR (RLAR). To identify and isolate the active components in the ethyl acetate fraction of the MA extract, high-speed countercurrent chromatography and Sephadex LH-20 column chromatography were performed and guided by an offline HPLC-ABTS assay and HPLC microfractionation AR assay...

Apigenin, a widely distributed flavone, exhibits excellent antioxidant, anti-inflammatory, and antitumor properties. In addition, the methylation of apigenin is generally considered to result in better absorption and greatly increased bioavailability. Here, four putative Class II methyltransferase genes were identified from the transcriptome sequences generated from the liverwort species Plagiochasma appendiculatum. Each was heterologously expressed as a His-fusion protein in Escherichia coli and their methylation activity against apigenin was tested...

INTRODUCTION: Flavonoids are converted to inactive metabolites like glucuronides in the gut, and circulate mainly as glucuronides in blood stream, resulting in low concentrations of active aglycones in plasma. It is therefore unclear how oral flavonoids exert their effects in tissues. We recently reported the plasma pharmacokinetics of some flavonoids and suggested the possibility that the absorbed flavonoids modified macrophage functions leading to enhance bacterial clearance. We aimed to confirm their pharmacological profiles focusing on tissue macrophages...

Following cardiovascular disease, cancer is the second leading cause of death in most affluent countries. The 13.3 million new cases of cancer in 2010 were predicted to cost US$ 290 billion, but the total costs were expected to increases to US$ 458 billion in the year 2030 on basis of World Economic Forum in 2011. More than half of all cancer cases and deaths worldwide are consider being preventable. From its inception, the disease control priorities series has focused attention on delivering efficacious health interventions that can result in dramatic reductions in mortality and disability at relatively modest cost...

The dietary derived isoflavone and oestrogen analogue, genistein, is known to perturb fundamental reproductive events such as implantation and embryo cleavage. However the question of whether genistein is able to traverse the oviduct epithelial monolayer and impact oviduct fluid secretion remains unclear. This study tests these research questions using a bioartificial oviduct to show that genistein permeates the oviduct lumen in vitro with a biphasic (burst and plateau) kinetic profile, faster than spontaneous diffusion, and alters the amino acid composition of in vitro derived oviduct fluid (ivDOF) but not as an oestrogen analogue...

Radiotherapy is a primary oncological treatment modality, which also damages normal tissue including the skin and causes radiation dermatitis (RD). Here, we explore the mechanism of acute epidermal damage in RD. Two distinctive phases in the damage response were identified: an early destructive phase where a burst of reactive oxygen species (ROS) induces loss of E-cadherin-mediated cell contact, followed by a regenerative phase where Wnt and Hippo signaling are activated. A blocking peptide, as well as a neutralizing antibody to E-cadherin, works synergistically with ionizing radiation to promote the epidermal damage...

Naturally occurring polymers are promising biocompatible materials that have many applications for emerging therapies, drug delivery systems and diagnostic agents. The handling and processing of such materials still constitutes a major challenge which can limit the full exploitation of their properties. This study explores an ambient environment processing technique: coaxial electrospray (CO-ES) to encapsulate genistein (an isoflavonoid and model drug), superparamagnetic iron oxide nanoparticles (SPIONs, 10-15 nm) and a fluorophore (BODIPY) into a layered (triglyceride tristearin shell) particulate system, with a view to constructing a theranostic agent...
