background calcium/calmodulin-dependent protein kinase iiα (camkiiα) may modulate the function of mu-opioid receptors by phosphorylation and therefore, be involved in development of morphine-induced analgesic tolerance. objectives the current study aimed to examine changes in gene expression of camkiiα in the lumbosacral cord and midbrain during induction of morphine analgesic tolerance. materi...
rna extraction is a prerequisite technique for gene expression studies, analyzing the etiology and disease progression, treatment effects, as well as designing the diagnostic methods. although many rna extraction kits have been commercialized, but these kits are expensive and are not accessible in some countries. many studies have shown that trizol is an applicable material for the rna extracti...
abstract: a pure nucleotide pool is an essential precursor of correct dna replication and prevention of mutagenesis and abnormality in a living cell. inosine triphosphatase (itpase) is a critical enzyme to remove any deaminated rough purine nucleotides such as inosine from nucleotide pool. it has been shown that the rate of substitution mutation in genomic dna increase by abnormal function and ...
conclusions the gp40/15 gene, which was cloned in the pet28a+, was successfully expressed and produced in e. coli. therefore, this protein can be used in future studies to develop recombinant vaccines and diagnostic kits. methods in this experimental study, the gp40/15 gene sequence was extracted from genbank (no. af155624) and cloned in the pet28a+ plasmid. colony polymerase chain reaction (pc...
sulfur mustard (sm) has been identified as an important chemical weapon. during the iran-iraq war of 1980-88, the extensive usage of sm against iranian civilians and military forces was proven. this agent has been shown to cause severe damage mainly in the skin, eyes, lungs, and respiratory tract in iranian veterans. the most common disease is bronchiolitis obliterans (bo)). sm incre...
background: the aim of this study was to evaluate over expression of epidermal growth factor receptor (egfr) gene in localized prostate cancers and determine its relation with clinical and pathological factors affecting the progression of the disease. methods: in the tissue samples of the patients with prostate cancer undergoing radical prostatectomy, egfr expression was evaluated by immunohist...
objective(s):previous studies demonstrate that changes in pre-mrna splicing play a significant role in human disease development. furthermore, many cancer-associated genes are regulated by alternative splicing. there are mounting evidences that splice variants which express predominantly in tumors, have clear diagnostic value and may provide potential drug targets. located on the x chromosome, ...
objective(s): we aimed to examine association of gene expression of mor1 and glun1 at mrna level in the lumbosacral cord and midbrain with morphine tolerance in male wistar rats. materials and methods: analgesic effects of morphine administrated intraperitoneally at doses of 0.1, 1, 5 and 10 mg/kg were examined using a hot plate test in rats with and without a history of 15 days morphine (10 mg...
introduction: in order to study the alterations of beta 1 and 2 integrins mrna level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. we used induction of chronic pain alone and in ...
mono-targeting by imatinib as a main antitumor agent does not always accomplish complete cancer suppression. 2,5-dimethyl-celecoxib (dmc) is a close structural analog of the selective cyclooxygenase-2 (cox-2) inhibitor, celecoxib, that lacks cox-2 inhibitory function. in this study, we aimed to show the apoptotic effects of imatinib in combination with dmc in human ht-29 colorectal cancer (crc)...
