background: breast cancer is one of the most prevalent malignancies among women in various countries. her2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. her2 gene encodes an 185kda transmembrane glycoprotein with 1255 amino acids. this active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. these...

background and objectives: the prevalence of multidrug resistant pseudomonas aeruginosa is the main reason of new drugs resurgence such as colistin. the main objectives of this study were to determine the antibiotic resistance pattern and the rate of colistin resistance along with its correlation with overexpression of mexab-oprm and mexxy-oprm efflux pumps among p. aeruginosa isolates. materia...

objective her-2/neu gene is overexpressed in diverse human cancers and studies suggest a role of its product – p185 protein – in tumor progression by specifically promoting the invasive capacity of tumor cells. our aim was to evaluate her-2/neu content in resectable gastric cancer in this geographical region and assess the relationship between p185 expression and clinicopathologic tumor paramet...

objective(s): the purpose of this study was to investigate the role of chloride channel protein 2 (clc-2) in glutamate-induced apoptosis in the retinal ganglion cell line (rgc-5). materials and methods: rgc-5 cells were treated with 1 mm glutamate for 24 hr. the expression of clc-2, bax, and bcl-2 was detected by western blot analysis. cell survival and apoptosis were measured by 3-(4,5-dimethy...

acute lymphoblastic leukemia (all) is one of the most prevalent hematologic malignancies in children. although the cure rate of all has improved over the past decades, the most important reason for all treatment failure is multidrug resistance (mdr) phenomenon. the current study aims to explain the mechanisms involved in multidrug resistance of childhood all, and introduces atp-binding cassette...

Background: Fibronectin type III domain-containing 5 proteins (Fndc5), an exercise hormone, formerly known as peroxisomal protein that was cloned in 2002. Transcript profile analysis of Fndc5 revealed high degree of expression in heart, skeletal muscle and brain. Our recent studies indicated a significant increase (approximately 10 folds) in mRNA level of Fndc5 when mouse embryonic stem cells w...


 Purpose: To investigate the effect of microRNA-612 (miR-612) on human colon cancer cells, and mechanism involved.
 Methods: Expressions miR-612 GPR132 were determined by quantitative real-time polymerase chain reaction (qRT-PCR)el , while cell viability was evaluated using counting kit-8 (CCK8) colony formation assays. Dual luciferase assay used to determine interaction between GPR1...

Functional and structural studies of membrane proteins usually require overexpression of the proteins in question. Often, however, the 'trial and error' approaches that are mainly used to produce membrane proteins are not successful. Our rapidly increasing understanding of membrane protein insertion, folding and degradation means that membrane protein overexpression can be more rationalized, bo...
