objective(s): although tumor necrosis factor-related apoptosis-inducing ligand (trail) can selectively induce apoptosis in tumor cells, more than half of tumors including non-small cell lung cancer (nsclc) exhibit trail-resistance. the purpose of this study was to determine whether subtoxic-dose cisplatin and trail could synergistically enhance apoptosis on nsclc cells and investigate its under...
Background: Over the past 15 years, significant insights have been gained into the roles of miRNAs in cancer. In various cancers, miRNAs can act as oncogenes, tumor suppressors, or control the metastasis process by modulating the expression of numerous target genes. This study is aimed at determining molecular network of miRNA-mRNA regulating lung cancer invasion, by bioinformatics approaches. ...
introduction radon is a colorless and tasteless gas which exists in most soils. it is a substance that poses a potential risk for lung cancer in case a person is exposed to high levels over long periods of time. the environmental protection agency (epa) estimates that 90% of lung cancers per year are caused by radon. the aim of this paper is to estimate the absorbed doses of 222rn by mcnpx simu...
mobasheri mr * (phd), hejazi a (msc) department of remote sensing, kntoosi university of technology, tehran, iran original article received: 16 jan 2014, accepted: 21 apr 2014 abstract introduction: air pollution may affect health through increasing respiratory and cardiovascular morbidities and mortalities. in this study, we investigated the correlation between the concentr...
Introdution: Recent studies identified the 15q14/15q25 chromosomal region as a susceptibility locus to lung cancer. This region includes CHRNA3, CHRNA5 and CHRNB4, genes, which coding for nicotinic acetylcholine receptor subunits in lungs and brain. The relationship between several polymorphisms in this locus and lung cancer risk has been widely investigated. The aim of this study was to survey...
Introduction: Lung cancer is one of the leading causes of cancer related deaths in the world. The incidence of lung cancer is increasing in India and there is a need to understand the natural history of this disease. Aim of the study: To study the clinico- pathological- radiological profile of patients diagnosed with lung cancer from January 2013 to May 2015 at a tertiary care teaching hospital...
Background and Aim: Lung cancer is the most common cancer among men around the world. The aim of this study was to determine the expression levels of CK19 mRNA marker in the affected patients’ peripheral blood. Materials and Methods: Thirty patients with lung cancer (NSCLC type) were compared with 30 healthy controls. After taking peripheral blood samples and extracting total RNA, cDNA was s...
objective(s): foxp3 gene is an x-linked gene that encodes foxp3 protein, an essential transcription factor in cd4+cd25+foxp3+ regulatory t (treg) cells. we aimed, in the present study, to investigate the association of two foxp3 polymorphisms, -2383 c/t (rs3761549) and ivs9+459 t/c (rs2280883), with lung cancer. materials and methods: in a case-control study we analyzed genotypes and alleles ...
background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...
abstractobjective: to investigate the impact of respiratory motion on localization, and quantification lung lesions for the gross tumour volume utilizing an in-house developed auto3dreg programme and dynamic nurbs-based cardiac-torso digitised phantom (ncat). methods: respiratory motion may result in more than 30% underestimation of the suv values of lung, liver and kidney tumour lesions. the m...
