conclusions based on our findings, we conclude that the separation and reproduction of adipose tissue cells is an appropriate method for purification of mscs in animal studies. regarding the histomorphometric and flow cytometry analysis results, we demonstrated the differentiation ability of mscs in normal medium and hope to employ these cells for the regeneration of damaged bone tissues in the...

objective(s): breast cancer is the most common type of cancer among women worldwide. this study investigated the expression and clinical significance of activating transcription factor 3 (atf3) in human breast cancer and its relationship with the clinical outcome of breast cancer.   materials and methods : atf3 expressions were detected in 114 primary breast cancer tissues and 114 adjacent norm...

background: cancer/testis antigens (ctas) are members of a group of proteins which are normally expressed in testis germ cells and to a lesser extent in the ovaries. because of recent reports about their aberrant and specific expression in some tumoral tissues, they may play a role as new candidates for targeted therapy. therefore, the study of the expression pattern of these biomarkers and its...

introduction: her2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. the purpose of this study was to determine the salivary levels and tissue expression of her2/neu in patients with head and neck squamous cell carcinoma (hnscc) and their correlation with clinicopathologic parameters.   materials and methods: enzyme-linked immunoso...

ischemia-reperfusion injury is the tissue damage happened when blood supply returns to the tissue after a period of ischemia or shortage of oxygen. this brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. the aim of this study is investigating the effect of hydroalcoholic extract of  cyperus rotundus l. on the expression of the bcl-x1 an...

Introduction: Metalloproteinases and their tissue inhibitors play an important role in the metastases formation. A multistage process of carcinogenesis requires the involvement of numerous enzymes and compounds that facilitate the expansion of tumor cells. The formation of metastases depends on both metalloproteinases and tissue inhibitors activation leading to the acti...

Introduction: One of the most important complications of exposure to noises is changes in the gene expression patterns. Irreversible damage to the inner ear, such as noise-induced hearing loss (NIHL), is caused by tissue damage and changes in the gene expressions in the auditory system. Changes in the GJB2 gene expression pattern lead to autosomal deafness at different loci. The present study a...

background: ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. this study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (figla), growth differentiation factor-9 (gdf-9), follicle-stimulating hormone receptor (fshr), and kit ligand after v...
