Background: As far as the role and amount of Transferrin receptor 2 (TFR2), which is the transferrin receptor gene, studies have been conducted, some of which confirming its relationship with gastric adenocarcinoma. The idea behind this study was to examine changes in the TFR2 gene expression in the tumor cells of gastric adenocarcinoma and comparing with gene expression in the normal tissue ad...
background and objectives: phospholipases are a group of enzymes that breakdown phospholipid molecules producing second products. these second products play a diverse role in the cell such as signal transduction and digestion in humans. in this study, the effect of phospholipids on the expression of pld genes of a. fumigatus was investigated. the pld genes of this fungus were also investigated ...
a new strategy for construction of synthetic gene encoding human basic fibroblast growth factor comprising dna annealing-ligation and augmentation by polymerase chain reaction was introduced. the sequence of the gene and corresponding amino acid chain were modified in order to increase stability of the protein. first, 300 bp and 160 bp fragments of the gene were assembled from 18 oligonucleotid...
introduction: the estrogen receptors are potential candidates in prognosis and particularly in predicting hormone response therapy in breast cancer. the aim of this study was to measure erα gene expression due to study of the association between erα expression, age and menopause of iranian women with breast cancer. methods: 21 adenocarcinoma cases with grade 2 and 10 normal samples were screene...
multiple sclerosis (ms) is a chronic inflammatory disease that leads to degeneration of the brain and spinal tissue. imbalances of cd4+ t cells including thelper1 (th1)/thelper2 (th2) and thelper17 (th17)/tregulatory (treg), their secreted cytokines and gene expressions, are important aspects of in immunopathogenesis of ms. vitamin a and its metabolites can regulate the immune system and appear...
given the difficulties in accessing articular cartilage as a source of chondrocytes to be used in fabricating cartilage constructs, alternative sources are required. the present study examined chondrocytes from costal cartilage for their suitability in cartilage tissue engineering. chondrocytes isolated from rat knee and rib hyaline cartilage were separately mixed with alginate and placed in a ...
cyclosporine a (csa), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. previous studies have shown that csa exposure enhances the production of reactive oxygen species (ros) and lipid peroxidation, which are directly involved in csa toxicity. to protect cells and organs against ros, the human body has evolved a...
the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...
the human granulocyte-macrophage colony stimulation factor (hgm-csf) gene was cloned in the pet 23a( +) expression vector under the control of strong bacteriophage t7 transcription and translation signals. the hgm-csf gene was transferred into e. coli strainbl21 (de3)plyss andiptg was used for induction of gm-csf gene. production of the target protein was obtained as revealed by elisa and weste...
conclusions it can be concluded that the nettle extract can reduce blood glucose levels in diabetic mice, at least partly, by influencing the glut2 gene expression in mice liver. results the results showed that the nettle extract significantly decreased high levels of blood glucose (p < 0.001). the nettle extract also had a preventive effect on decrease in body weight. in addition, the results ...
