Exploitation of Herpesviral Transactivation Allows Quantitative Reporter Gene-Based Assessment of Virus Entry and Neutralization

Human papillomavirus genotype 16 pseudovirus production and purification in HEK-293FT cells

Introduction: Human papillomavirus (HPV) is the main causative agent of cervical cancer worldwide leading to a big health problem, especially in the developing countries. Among 14 common high-risk genotypes, HPV16 accounts for more than 50% of all cervical cancers. The current prophylactic vaccines against HPV infection are based on L1 protein. Due to some drawbacks in the current vaccines such...

An Enterovirus-Like RNA Construct for Colon Cancer Suicide Gene Therapy

Background: In gene therapy, the use of RNA molecules as therapeutic agents has shown advantages over plasmid DNA, including higher levels of safety. However, transient nature of RNA has been a major obstacle in application of RNA in gene therapy. Methods: Here, we used the internal ribosomal entry site of encephalomyocarditis virus and the 3’ non-translated region of Poliovirus to design an en...

Quantitative Studies on the Neutralization Reaction between African Horse-sickness Virus and Antiserum

ساخت وکتور ریپورتر القایی لوسیفراز برای ردیابی فعالیت ویروس HTLV-1

 Background: HTLV-1 (Human T_cell lymphotropic virus type), with about 20 million individuals infected worldwide, is a global health problem and is endemic in certain area such as Japan and Khorasan province of Iran. HTLV-1 is the causative agent of progressive diseases, Adult T cell Leukemia (ATL), and HTLV-I Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) which have no ...

تولید هورمون رشد انسانی نوترکیب توسط سلول تخمدان هامستر چینی و بررسی فعالیت زیستی آن به روش سنجش گزارشگر ژنی

 Background: Cultivated mammalian cells, because of their capacity for proper protein folding, assembly and post–translational modification, have become the dominant system for production of recombinant proteins in clinical application. Therefore, the quality and efficacy of protein can be superior when expressed in mammalian cells compared to other hosts such as bacteria. Gene reporte...
