Exosomes, as a mediator of cell-to-cell transfer of genetic information, act an important role in intercommunication between tumor cells and their niche including fibroblasts, endothelial cells, adipocytes and monocytes. Several studies have shown that tumor cells can influence their neighboring cells by releasing exosomes. These exosomes provide signaling cues for stimulation, activation, prol...

The methanolic extracts of Indigofera aspalathoides (MEIA) and Wedelia calendulaceae (MEWC) were evaluated for their anticancer activity against Ehrlich Ascites Carcinoma (EAC) in Swiss albino mice. On day 1, the extract of Indigofera aspalathoides at a dose of 250 and 500 mg/kg body weight and the extract of Wedelia calendulaceae at a dose of 250 and 500 mg/kg body weight were administered ora...

background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...

The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...

Background: In this study, the effects of three structural analogues of adenosine upon proliferation of human tumor cells were investigated. Previous research showed a cytotoxic effect of adenosine via A3 receptor and A1 receptor and sometimes this effect was receptor independent. The researches showed a differential cytotoxic effect of adenosine and its A3 agonists on cancerous cells, while ot...

background: the current study investigated the possible role of the cell cycle regulator, cyclin-dependent kinases regulatory subunit-2; the angiogenic factor, plateletderived endothelial cell growth factor; and the cell adhesive molecule, neural cadherin, as prognostic factors in schistosomal and non-schistosomal-associated urothelial carcinomas. we also investigated the possible correlation b...

isolation of some potent anti-tumor compounds from medicinal plants has motivated researchers to screen different parts of plant for their anti-tumor effects. it has been reported that several species of conifers posses’ cytotoxic activities on some tumor cell lines. here branchlets and berries of juniperus foetidissima and j. sabina were collected, dried and ethanol extracts of them obtained u...

  Background and Objectives: Giant cell Tumor of bone (GCT) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. Histological features of the tumor often could not predict its future biologic behavior, so it is just called ''Giant cell tumor'' without indicating maligna...
