background: some of metal ions as environmental pollutants show estrogenic activity. this xenostrogenic compounds can be caused carcinogenicity in organs. the mechanism of carcinogenicity of metal ions is not clarified. objectives: in this study, we investigated the transcriptional effects of variety of metal ions on the bovine oxytocin and the thymidine kinase-ere promoter by estrogen receptor...
introduction: endothelial progenitor colony forming unit-endothelial cells (cfu-ec) were first believed to be the progenitors of endothelial cells, named endothelial progenitor cells. further studies revealed that they are monocytes regulating vasculogenesis. the main hindrance of these cells for therapeutic purposes is their low frequency and limited replicative potentials. this study was unde...
soybean isoflavone genistein has multiple anticancer properties and its pro-apoptotic and anti-proliferative effects have been studied in different cancer cells. however, the mechanisms of action of genistein and its molecular targets on human colon cells have not been fully elucidated. therefore, caspase-3 and p38 mitogen-activated protein kinase (p38 mapk) as the main therapeutic targets were...
Background and purpose: Interest into targeting PI3K in cancer has increased by the recent disclosure that aberrant activity of PI3K/Akt signaling pathway is associated with disease recurrence and poor outcome in different malignancies. The aim of this study was to investigate the potentiating effect of PI3K inhibitor, GS-1101 on doxorubicin-induced cell death in acute lymphoblastic leukemia-de...

materials and methods: nrvms were adopted as the cell model to investigate the roles of pi3k/akt and foxo3a in mediating hyperglycemia-induced apoptosis in cardiomyocytes. annexin-v-fitc staining and pi staining were used to evaluate the apoptosis in nrvms under indicated conditions of serum starvation, high glucose exposure, and pharmacological or genetic manipulations on the expressions of pi...

lentinan a polysaccharide from medicinal mushroom i.e lentinus, has been known to have anticancer properties. telomerase activity is not observed in normal healthy cells, whereas in cancerous cells telomerase expression is high. telomerase represents a promising cancer therapeutic target. we investigated the inhibitory effect of lentinan on telomerase reverse transcriptase gene (htert) which is...
