[ 1 ] - Recombinant Expression of the Non-glycosylated Extracellular Domain of Human Transforming Growth Factorβ Type II Receptor Using the Baculovirus Expression System in Sf21 Insect Cells

Transforming growth factor beta (TGFβ1, β2, and β3) are 25 kDa disulfide-linked homodimers that regulate many aspects of cellular functions, consist of proliferation, differentiation, adhesion and extracellular matrix formation. TGFβs mediate their biological activities by binding of growth factor ligand to two related, functionally distinct, single-pass transmembrane receptor kinases, known as...

[ 2 ] - In Silico Analysis of Primary Sequence and Tertiary Structure of Lepidium Draba Peroxidase

Peroxidase enzymes are vastly applicable in industry and diagnosiss. Recently, we introduced a new kind of peroxidase gene from Lepidium draba (LDP). According to protein multiple sequence alignment results, LDP had 93% similarity and 88.96% identity with horseradish peroxidase C1A (HRP C1A). In the current study we employed in silico tools to determine, to which group of peroxidase enzymes LDP...

[ 3 ] - Molecular Docking and Rare Codons Evaluation in the Luciola Lateralis luciferase, an in Silico Study

Luciferase enzymes are involved in the bioluminescence reaction (light emission by living organisms). The bioluminescence process is a widespread phenomenon in the Nature. These enzymes are identified in some domains of life, but the luciferases from lampyrid genus are considered of for biological applications. The molecular cloning of a new type of firefly luciferase from Luciola lateralis was...

[ 4 ] - Water-based Double Layer Functionalized Iron Oxide Nanoparticles for Enhanced Gene Delivery Applications

Iron oxide nanoparticles (magnetite (Fe3O4), hematite (Fe2O3)) have been received increasing attention in drug and gene delivery. In this work, water-base double layer functionalized iron oxide nanoparticles (DL-IONPs) were designed and prepared of a biodegradable, biocompatible carrier by co-precipitation method with high DNA loading capacity due to self-assembly of a second organic layer. The...

[ 5 ] - مقایسه بیان دو ژن مرجع GAPDH و EF1α در کدو (Cucurbita pepo L.) تحت پیش تیمار اسپرمین و تنش شوری

یکی از اولین اثرات تنش‌های مختلف، تغییر در بیان ژن‌های مربوط می‌باشد. بنابراین مطالعه بیان ژن برای بررسی اثر تنش دارای اهمیت ویژه است. بررسی بیان یک ژن نیاز به اندازه‌گیری دقیق و تجدید پذیر میزان mRNA به صورت کمی یا نیمه‌کمی دارد. برای بهینه‌سازی (نرمال کردن) داده‌ها، انتخاب ژن‌های کنترل درونی (مرجع یا خانه‌دار) مناسب، که بیان آن‌ها در طول تیمار نوسان نداشته باشند، اهمیت دارد. ژن‌های GAPDH و EF...

[ 6 ] - بررسی میزان تغییر بیان و جهش های ژن های P53و MICAL2در مبتلایان به سرطان معده در شهر کرمان

Background and Aim: Stomach cancer is one of the most common cancers after lung cancer and the second cause of cancer deaths worldwide. Changes in the expression level of genes are one of the most important factors in cancers. Among them p53 and MICAL-2 were found have changes in their expression levels. P53 gene plays an important role as a tumor suppressor which is also regulates the cell cy...

[ 8 ] - بیان پروتئین نوترکیب TGF β1 در گیاه توتون و بررسی تاًثیر پروتئاز فورین در پردازش فرم نهفته‌ی این پروتئین

TGFβ1 ، یک پروتئین تنظیمی چندکاره است که در طیف وسیعی از فعالیت‌های بیولوژیکی مداخله می‌نماید. این پروتئین، ابتدا به صورت یک فرم پیش ساز غیرفعال، حاوی 390 اسید آمینه سنتز می‌شود که قبل از اتصال به گیرنده‌های TGFβ1، تحت تاًثیر برش پروتئولیتیکی، فرم بالغ TGFβ1 از پروپپتید آن جدا می‌گردد. فرم بالغ این پروتئین شامل 112 اسید آمینه از انتهای C ترمینال فرم غیرفعال آن است. در این مطالعه، در ابتدا توانای...

[ 9 ] - Changes of Genetic Loci among Gastric Cancer Patients, Southeastern Iran, 2017

Background: Characterization of genes and precise assessment of the number of copies are crucial for understanding the basis of emergence, progression, and identification of predictive markers of tumor malignancy. This study aimed to investigate the role of the changes in some central genes in gastric cancer. Materials and Methods: In this experimental study, 30 patients with gastric surgery w...
