Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression ...
Introduction: The features of a cell can be extracted from its gene expression profile. If the gene expression profiles of future descendant cells are predicted, the features of the future cells are also predicted. The objective of this study was to design an artificial neural network to predict gene expression profiles of descendant cells that will be generated by division/differentiation of h...
an agrobacterium-mediated transient gene expression assay was carried out in alfalfa (medicago sativa) leaves for expression of a chimeric gene encoding a part of capsid protein of foot and mouth disease virus called vp1. the plant leaves were transformed via agroinfiltration procedure. the presence of the foreign gene and its expression in transformed plants were evaluated by polymerase chain ...
Introduction: Prostate cancer is the second most common cancer and the leading cause of cancer-related deaths worldwide. In the present study, the expression level of glycine N-methyl transferase gene (GNMT) was investigated in prostate cancer tissue. The GNMT enzyme is encoded by the GNMT gene. Increased GNMT gene expression increases the conversion of glycine to sarcosine and results in the e...
Backgrounds: Helicobacter pylori is associated with the development of gastric cancer. The thiol peroxidase enzyme, encoded by the tagD gene in this bacterium, plays an important role in bacterial attachment and colonization in the human stomach. The aim of this study was to investigate the expression of VPR2 gene in AGS cells transfected with recombinant vector of helicobacter pylori tagD gene...

background: today, despite the many advances in early detection of diseases, cancer patients have a poor prognosis and the survival rates in them are low. recently, microarray technologies have been used for gathering thousands data about the gene expression level of cancer cells. these types of data are the main indicators in survival prediction of cancer. this study highlights the improvement...
the gene encoding the human basic fibroblast growth factor (hbfgf) has been already chemically-synthesized and cloned in pet-3a expression vector (pasteur institute of iran). in the present study, we compared the level of expression of this synthetic hbfgf and its related cdna in escherichia coli. the pbr322-cdna of hbfgf supplied by dr. seno (from molecular biology dept, okaido prefectural uni...
در این تحقیق اثر فلزات سنگین روی رشد گیاه littoralis aeluropus و الگوی بیان ژنهای رمز کننده na+/h+ آنتی پورتر غشای پلاسمایی و واکوئلی در این گیاه مورد بررسی قرار گرفت. به همین منظور گیاهچهها به صورت جداگانه تحت تنش فلزات سنگین سرب ، نقره و جیوه و شوری قرار گرفتند. صفات وزن ریشه، وزن ساقه، وزن کل، طول ریشه، طول ساقه، طول کل گیاه و میزان تجمع فلزات ذکر شده در گیاه اندازهگیری شد و تغییرات بیان ...
the green fluorescent protein (gfp) was originally isolated from the jellyfish aequorea victoria that fluoresces green when exposed to blue light. gfp protein is composed of 238 amino acids with the molecular mass of 26.9 kd. the gfp gene is frequently used in cellular and molecular biology as a reporter gene. to date, many bacterial, yeast , fungal, plants, fly and mammalian cells, including h...
