Kaposi's sarcoma associated herpesvirus (KSHV) is associated with Kaposis's sarcoma (KS), primary effusion lymphoma and multicentric Castleman's disease. KSHV encodes at least 8 open reading frames (ORFs) that play important roles in its lytic DNA replication. Among which, ORF6 of KSHV encodes an ssDNA binding protein that has been proved to participate in origin-dependent DNA replication in tr...
human immunodeficiency virus (hiv) infection is the major problem in the world. nowadays, new anti-retroviral drugs are extracted from medicinal plants, make an important role to supersede synthetic drugs with different side effects. in this study, we studied the salix aegyptiaca l extract, iranian herb, as an anti-hiv drug with anti-retroviral effects. we used a single cycle replicable (scr) h...
introduction: glycoprotein b (gb) is the major antigen for induction of humoral responses against human cytomegalovirus (hcmv) making it an attractive candidate for immune prophylaxis. in the present study, the humoral immune response of balb/c mice to a truncated hcmv gb protein fused with gfp was evaluated. methods: the truncated gb coding sequence was synthesized and cloned in pegfpn1 eukary...
Cell-derived exosomes are leading candidates for in vivo drug delivery carriers. In particular, exosomes derived from 293T cells are used most frequently, although exosome dosing has varied greatly among studies. Considering their biological origin, it is crucial to characterize the molecular composition of exosomes if large doses are to be administered in clinical settings. In this study, we p...
OBJECTIVE To construct a lentiviral vector expressing HIV-1 Tat and identify its expression in 293T cells. METHODS The gene fragment of HIV-1 Tat101 was subcloned to lentiviral transfer vector pHAGE-CMV-MCS-IZsGreen, which was named pHAGE-Tat. Then the constructed pHAGE-Tat was used to co-transfect the packing 293T cells, together with the packaging plasmids pMD2.G and psPAX2. The packaged vi...
Background: Human coagulation factor IX (hFIX) is a glycoprotein with two N-glycosylation sites at the activation peptide. Since the activation peptide is removed in mature hFIX, the exact role of N-glycosylation is unclear. To investigate the role of N-glycosylation in the secretion and activity of hFIX, we inhibited N-glycosylation by tunicamycin in the stable Human Embryonic Kidney (HEK)- c...
Recombinant protein expression in bacteria, typically E. coli, has been the most successful strategy for milligram quantity expression of proteins. However, prokaryotic hosts are often not as appropriate for expression of human, viral or eukaryotic proteins due to toxicity of the foreign macromolecule, differences in the protein folding machinery, or due to the lack of particular co- or post-tr...
افزایش کارآیی فرآیند ترشح بوسیله طراحی و یا انتخاب یک پپتید نشانه مناسب، می تواند به عنوان راهکاری جدید برای افزایش بیان پروتئین های نوترکیب در سامانه های بیانی هترولوگ مورد استفاده قرار گیرد. در ارتباط با بهینه سازی بیان فاکتور 9 انعقادی انسانی در رده های سلولی پستانداران، اثر پپتید نشانه های پروتئین های لوسیفراز از جاندار دریایی به نام gaussia princeps در مقایسه با عملکرد پپتید نشانه بومی فاک...
امروزه سرطان دهانه ی رحم به عنوان دومین عامل مرگ و میر بر اثر سرطان در میان زنان، به عنوان یکی از معضلات بهداشتی به ویژه، در کشورهای در حال توسعه به حساب می آید. مشخص شده است که سرطان دهانه ی رحم ارتباط زیادی با عفونت های ویروس پاپیلومای انسانی دارد. انکوژن های ویروسی e7 و e6، دائماً به وسیله ی سلول های توموری بیان می شوند، به همین دلیل، اهداف ایمنی زایی مناسبی جهت استفاده در واکسن های درمانی ژن...
