[ 2 ] - Periplasmic Expression of TNF Related Apoptosis Inducing Ligand (TRAIL) in E.coli
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of TNF family, is an interesting ligand which selectively induces apoptosis in tumor cells and, therefore, it has been developed for cancer therapy. This ligand has been produced by various hosts such as E.coli. However, protein expression in E.coli cytoplasm leads to problems such as incorrect folding, reduction in biolo...
[ 3 ] - Cloning and Expression of TNF Related Apoptosis Inducing Ligand in Nicotiana tabacum
Molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. Human TNF Related Apoptosis Inducing Ligand (TRAIL) as a promising biopharmaceutical candidate has been produced in different expression hosts. However, little attention has been paid to molecular farming of the TRAIL in spite of numerous advantages of plant expression systems. Theref...
[ 4 ] - A convenient method to generate methylated and un-methylated control DNA in methylation studies
Methylated and un-methylated control DNA is an important part of DNA methylation studies. Although human and mouse DNA methylation control sets are commercially available, in case of methylation studies on other species such as animals, plants, and bacteria, control sets need to be prepared. In this paper a simple method of generating methylated and un-methylated control DNA is described. Whole...

[ 7 ] - شیوع آدنوویروس 36 انسانی و ارتباط آن با چاقی و فاکتورهای لیپیدی در جمعیت قند و لیپید تهران
مقدمه: امروزه چاقی یکی از مشکلات مهم بشری به شمار می‌رود و تداوم آن در بروز بیماری‌های قلبی ـ عروقی و دیابت موثر است، اما ایده‌ی وجود منشای ویروسی برای آن در مقایسه با دلایل ژنتیکی و سایر عوامل محیطی کمتر مورد مطالعه قرار گرفته است. بنابراین، هدف مطالعه‌ی حاضر بررسی میزان شیوع Adv36 و ارتباط آن با فاکتورهای چاقی و لیپیدهای سرمی در جمعیت قند و لیپید تهران بود. مواد و روش‌ها: در مطالعه‌ی مقطعی حا...
[ 8 ] - کاربرد باکتری ها در درمان سرطان
مقاومت به درمان های ضد سرطان در بیماران مبتلا به تومورهای جامد پیشرفته نیاز به درمان های جدید را آشکار می سازد. در درمان ایده آل، سلول های سرطانی با حداقل عوارض جانبی ریشه کن خواهند شد. باکتری ها به روش های مختلف در درمان سرطان به کار می روند که کاربرد آن به صورت اثرات مستقیم ضد تو موری و یا انتقال عواملی دارای این آثار می باشد. دو روش برای استفاده از باکتری ها به عنوان وکتور وجود دارد، شامل ه...
[ 9 ] - بیان آلبومین سرم انسانی نوترکیب در باکتری اشرشیا کلی سویه (DE3) BL21
سابقه وهدف: آلبومین سرم انسان از مهم ترین ترکیبات سیستم گردش خون می باشد . این پروتئین حامل بسیاری از هورمون ها ومتابولیت ها در بدن بوده و در تثبیت حجم خون و درمان انواع سوختگی ها مؤثر می باشد. چون تهیه آن از پلاسمای خون پرهزینه بوده و همراه با آلودگی به پاتوژن ها ی مختلف است، تولید آن توسط روش های بیوتکنولوژی ضروری به نظر می رسد مواد و روش ها: ژن آلبومین سرم انسان ( HSA ) براساس توالی موجود در...
[ 10 ] - Cloning and Expression of Influenza H1N1 NS1 Protein in Escherichia Coli BL21
Background:Influenza virus is globally pathogenic and it is usually associated with zoonotic respiratory diseases. This virus has caused a number of pandemics with a high mortality rate. The non-structural (NS1) protein of influenza A viruses is a non-essential virulence factor that has multiple accessory functions during viral infection. This protein is highly conservative. It has been shown t...
[ 11 ] - مروری بر تولید و کاربرد آنتی بادی های منوکلونال تک زنجیره ای: scFv
Abstract Background: Since the development of monoclonal antibodies by hybridoma technology the use of antibodies in targeted therapy has been considered. ScFv (single-chain variable fragment) is a small fragment of monoclonal antibody which binds to its target, especially. The goal of this study, is introducing of scFv, its production pathways as well as its diagnostic and therapeutic appl...
[ 12 ] - Immunization against Leishmania major infection in BALB/c mice using a subunit-based DNA vaccine derived from TSA, LmSTI1, KMP11, and LACK predominant antigens
Objective(s): To design a multivalent DNA vaccine encoding the most immunogenic regions of the Leishmania major antigens including TSA (Thiol-specific antioxidant protein), LmSTI1 (Leishmania major stress-inducible protein1), LACK (Leishmania homologue of receptors for activated C Kinase), and KMP11 (kinetoplastid membrane protein-11) on BALB/c mice.M...
[ 13 ] - The Effect of Human Recombinant Tumor Necrosis Factor Receptor-2 on Reducing Inflammatory of Collagen -Induced Arthritis in Balb/c Mice
Background: The tumor necrosis factor alpha (TNFα) is a cytokine that produced principally by monocyte/macrophages and T lymphocytes, respectively. TNFα is recognized as the primary mediator of immunity in inflammation reaction. One important application of Tumor Necrosis Factor Receptor 2 (TNFR2) is for the treatment of autoimmune diseases like rheumatoid arthritis (RA).<br /...
