Background: Radiotherapy is an effective and important therapeutic method for breast cancer, but at the same time it has a radiation-induced bystander effect on normal tissue around the tumor. Repair of double-strand breaks (DSBs) by normal cells can reduce the extent of damage caused by this effect. Caveolin-1 (Cav-1) is an important regulatory molecule in cell signal transduction. However, th...
The ethyl acetate partition of dried methanolic extract of aerial parts of Euphorbia microsciadia (Euphorbiaceae) afforded three pentacyclic triterpenes, betulinic acid (1) from lupane type, oleanolic acid (2) from oleane type and ursolic acid (3) from ursane type triterpenes that are reported for the first time in this plant. These three compounds were structurally compared through their mass ...
Our previous studies revealed an inhibitory effect of ICD-85 (Venom derived peptides) on breast cancer cell line MDA-MB231. ICD-85 was also confirmed by in-vivo studies to suppress the breast tumor in mice. However, the exact mechanism of ICD-85 was unknown. Hence, the present study was undertaken to assess the mechanism of ICD-85 effect as an anti-proliferative agent of cancer cells. The effec...
Background: Multiple Myeloma is a Plasma Cell Malignancy. Since the study of pathogenicity mechanisms and messenger pathways involved in the causative agent cells is important in the laboratory environment and close to the physiological environment of the body, therefore, the best environment for the study of cells in the laboratory environment, an environment most closely resembling the physio...
background: breast cancer is the most common diagnosed cancer among women in the world. snail1 plays a role in the development of the invasive phenotypes of cancer, neural cell differentiation, cell division and apoptosis in tumor cells. traces of snail1 in metastasis of breast cancer to bone are observed. the aim of this study was to investigate the effect of specific snail1 sirnas on the prol...
objective: we introduce an rgd (arg-gly-asp)-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. materials and methods: in this experimental study, the peptide was immobilized on an electrospun nanofibrous polycaprolactone/gelatin (pcl/gel) hybrid scaffold by a chemical bonding approach to improve cell adhesion properties of the scaffold. a...
objective: vascular endothelial growth factor (vegf) and vegf receptors (vegfrs) play important roles in angiogenesis of different developmental mechanisms such as wound healing, embryogenesis and diseases, including different types of cancer. vegfr2 is associated with cell proliferation, migration, and vascular permeability of endothelial cells. blocking vegf and its receptors is suggested as ...
objective: tissue engineering is an (interdisciplinary field that applies polymeric scaffolds to control tissue formation in three-dinemtion (3d). the scaffold provides the microenvironment (synthetic temporary extracellular matrix) for regenerative cells, supporting cell attachment, proliferation, differentiation, and neo tissue genesis due to their suitable chemical, physical and biological s...
