background: the ectopic expression of receptor tyrosine kinase ror1 has been reported in patients with hematological malignancies such as chronic lymphocytic leukemia and acute lymphoblastic leukemia. here we report, for the first time, expression of ror1 gene in both tumor tissues and peripheral blood mononuclear cells (pbmc) from patients with renal cancer (rc). methods: in the current study,...
hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...
calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...
background: vast variety of intermediate factors including cell cycle regulators, growth factors, transcription factors, and signaling pathways are involved in hematopoietic stem cell (hsc) commitment and differentiation into distinct lineages. vhl, ecad, and runx3 are among these. epigenetics is currently introduced as a potential mechanism to control the gene regulation. the aim of this study...
serological methods are commonly used methods for detection of viruses. preparation of pure viral antigens is a crucial step in production of antibodies required for serological studies. in this research the gene encoding coat protein of a beet western yellows virus (bwyv) isolate from iran was amplified by pcr and was ligated into a bacterial expression vector (pet26b) to obtain pet-bwyv-cp cl...
background:class ii transactivator (ciita) is a dominanttranscriptional element, controlling numerous genes in theimmune system. ciita is expressed in a constitutive pattern inantigen presenting cells although its expression can occur inother cell types. since the revelation of ciita, there have beenconsiderable advances toward understanding its role as anactivator of mhc ii genes in humans and...
background: vp4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. vp4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. methods: simian rotavirus sa11 gene 4 cdna was cloned into a cloning plasmid pdonrtm by recombination reaction using clonase ii enzyme mix. the resulting clone was c...
background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). testis specific chromodomain protein y 1 (cdy1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the re...
ژن tlr4 بر روی کروموزوم 17 قرار گرفته و دارای 3 اگزون و 2 اینترون است. این ژن باعث سنتز پروتئینی با تعداد843 اسید آمینه می شود که تنظیم و شروع کننده یپاسخ های ایمنی به هنگام آلودگی با باکتری های گرم منفی است. هدف از این مطالعه تجزیه و تحلیل ساختاری ژن tlr4 و ارتباط آن با صفات ایمنی در دو سویه بومی و تجاری بود. برخی از صفات ایمنی مثل میزان عیار پادتن های تولید شده علیه srbc (عیار پادتن کل، ta؛ ع...
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...
