breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...

EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...

Background: Chemo-immunotherapy is one of the new achievements for treatment of cancer, by which the success of anti-cancer therapy can be increased. In vitro studies have been shown that Arteether (ARE) induces apoptosis in tumor cells, but not in normal cells. Objective: To investigate the cytotoxic and immunomodulatory properties of Arteether in-vivo and in-vitro. Methods: In this study, we ...

Objective(s): Controversial results have been reported regarding the anti-tumor properties of extracellular vesicles derived from mesenchymal stem cells (MSCs). The present study was conducted to evaluate whether secretome derived from Human Wharton’s jelly mesenchymal stem cells (hWJMSCs) may stimulate or inhibit breast cancer growth in vitro and in vivo.<st...

Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...

objective: lumbar spinal canal stenosis (lscs) has prominent position in spinal disorders of the elderly. ligamentum flavum hypertrophy plays a dominant role in narrowing of the lscs. there are some clues that ligamentum flavum hypertrophy is associated with diabetes mellitus. our objective was comparison of histological properties of ligamentum flavum in lumbar spinal canal stenosis patients w...

Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...

ebv-carrying human cell lines, depending on whether the cells are derived from burkitt&apos;s lymphoma (bl) tumor biopsies or transformed by ebv in vitro, have different growth properties in vitro. in contrast, there are no clear differences between tamarin tumor lines and tamarin lcls in vitro. both types of tamarin cell lines could grow in agarose and formed colonies unlike human lcls, althou...

background colorectal cancer (crc) is the second most common malignancy in the world.  however, its mortality rate can be reduced if diagnosed early. p33 ing1b is a tumor suppressor protein, which plays a role in growth control and apoptosis. suppression of p33 ing1b is associated with the loss of cellular growth control. however, p33 ing1b expression in crc and its correlations with clinicopat...
