genistein/sarcoma

BACKGROUND: Ewing's sarcoma is a pediatric tumor that mainly occurs in soft tissues and bones. New therapeutic strategies are urgently needed for treatment of Ewing's sarcoma. We examined for the first time the efficacy of N-(4-hydroxyphenyl) retinamide (4-HPR) and genistein (GST) alone and also in

The aim of this work was to investigate the radiosensitization effects of genistein on mice sarcoma cells and the corresponding biological mechanisms in vitro and in vivo Using the non-toxic dosage of 10 μM genistein, the sensitizer enhancement ratios after exposure to X-rays at 50% cell survival

BACKGROUND The estrogen-like soy isoflavone genistein can suppress the growth of a number of different types of cancer cells, but its effect on uterine sarcoma is unknown. METHODS The impact of genistein on the proliferation of three uterine sarcoma cell lines, MES-SA, MES-SA-Dx5 and SK-UT-1, was

Effects of genistein on invasion and matrix metalloproteinase activities were investigated in HT1080 human sarcoma cells. Invasion of HT1080 cells through reconstituted basement membrane was inhibited when the cells were treated with 100 micromol/L and 200 micromol/L genistein. At the same

We have observed that the tyrosine kinase inhibitors genistein and tyrphostin can selectively block angiotensin II mediated and vasopressin-mediated contractions in porcine coronary arterial strips, without affecting the action of acetylcholine. Therefore, we assessed the presence of tyrosine kinase

Possible regulation of fast Na+ channels by tyrosine kinase was examined in human uterine smooth muscle cell line, using whole-cell voltage clamp (at a holding potential of - 90 mV). Bath application of genistein, an inhibitor tyrosine kinase, decreased the fast Na+ current (INa(f))

Human herpesvirus 8 (HHV-8; Kaposi's sarcoma-associated herpesvirus) envelope glycoprotein gB possesses an RGD motif, interacts with alpha 3 beta 1 integrin, and uses it as one of the entry receptors. HHV-8 induces the integrin-dependent focal adhesion kinase (FAK), a critical step in the outside-in

We have previously shown that an exogenous type I collagen matrix can regulate expression of mRNA for parathyroid hormone (PTH)-related protein (PTHrP) and its receptor, the PTH/PTHrP receptor, in the UMR106-06 osteogenic sarcoma cell line, which is considered to be representative of a relatively

Oncostatin M (OM) is a polypeptide cytokine that induces autocrine and paracrine effects on AIDS-Kaposi's sarcoma (KS) cells (Nair et al., Science, 255, 1430-1432, 1992; Miles et al., Science, 255, 1432-1434, 1992). The signalling pathways underlying this activation are largely unknown. We have

Transformation of embryonic hamster fibroblasts by the Rous sarcoma virus results in sharp increase of the turnover rate of one of cellular phospholipids-phosphatidylcholine. The decrease in the rate of virus-transformed cells (HETSR strain) during the monolayer formation is attended by additional

OBJECTIVE Nephrotic syndrome is a chronic disease especially common in the childhood and adolescence. Reactive oxygen species (ROS) and free radicals have significant role in the pathogenesis of nephrotic syndrome. The aim of this study was to evaluate the effect of soy protein and genistein (main

In the present study, we evaluated whether motility of Kaposi's sarcoma (KS) cells induced by platelet-activating factor (PAF) is dependent on the regulation of adherens junctions components. The results obtained indicate that PAF dose and time dependently reduced the endogenous expression of the

BACKGROUND Canonical Wnt signaling plays a key role in tumor cell proliferation, which correlates with the accumulation of β-catenin in cell due to inactivation of glycogen synthetase kinase-3 β. However, uncontrolled expression of β-catenin leads to fibromatosis, sarcoma and mesenchymal tumor

Human herpesvirus 8 (HHV-8) or Kaposi's sarcoma-associated herpesvirus, implicated in the pathogenesis of Kaposi's sarcoma, utilizes heparan sulfate-like molecules to bind the target cells via its envelope-associated glycoproteins gB and gpK8.1A. HHV-8-gB possesses the Arg-Gly-Asp (RGD) motif, the

Signal transduction capacity in human cancer cells is constitutively up-regulated by the markedly increased steady-state activities of the three synthetic enzymes, PI kinase, PIP kinase and PLC, which catalyze the conversion of PI to the second messengers IP3 and DAG. This evidence is supported by
