background and objective: inflammatory pseudotumor is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. the aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflam...
2*-Deoxycoformycin (dCF) as a single agent hasbeenreported tobe lesseffectiveagainst myeloid than against lymphoid malignancies in clinical trials. However, previous studies have shown that in the presence of 2*-deoxyadenosine (dAd), human monocytoid leukemia cell lines are much more sensitive to dCF with regard to the inhibition of cell proliferation. Thus, dCF might be useful for treating mon...
Introduction: To increase therapeutic ratio, using radio-sensitizers is recommended and nowadays some types of them are utilized clinically. In recent years, Gold nanoparticles (GNPs) were considered as radio-sensitizers in many studies due to high atomic number. Although theoretical works showed that GNPs have an insignificant effect at MV energies, some In-vitro and In-vivo s...
Primula auriculata (Tootia) is one of the most important local medicinal plants in Hamedan district, Iran. To investigate cytotoxicity and apoptosis induction of crude methanolic extract and different fraction of it we compared several methods on HT-29 human colon Adenocarcinoma cells. Cancer cell proliferation was measured by 3-(4, 5‑dimethylthiazolyl)-2, 5‑diphenyl‑tetrazolium bromide (MTT) a...
Interleukin 8 is a neutrophil chemotactic and stimulating cytokine induced by various inflammatory stimuli, including tumour necrosis factor, interleukin 1, and endotoxin. The ability of HT 29/19A enterocytes to synthesise interleukin 8 was studied. The results show that interleukin 1 is an important stimulus for interleukin 8 synthesis and secretion by HT 29/19A cells, being more potent than t...
Phosphorylation events in cellular signaling cascades triggered by a variety of cellular stimuli modulate protein function, leading to diverse cellular outcomes including cell division, growth, death, and differentiation. Abnormal regulation of protein phosphorylation due to mutation or overexpression of signaling proteins often results in various disease states. We provide here a list of prote...

Background: Electroporation has become a routine technique for rapid drug delivery for the treatment of cancer. Because of its simplicity and wide range of application, it has been applied for the transfer of gold-nanoparticles and can facilitate entry into target cancer cells. Objective: The aim of this study is finding optimal conditions in order to obtain high GNPs- uptake and cell via...
Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...
Background: Colorectal cancer (CRC) is attributed as one of the most common malignancies worldwide. CD133 molecule, as a pentaspan transmembrane glycoprotein, confers stem cell-related characteristics, including self-renewal and multi-directional differentiation capability. CD133 plays important roles in the progression of CRC by conferring apoptotic resistance and migration ab...
