Ricin toxin-binding subunit B (RTB) is a galactose-binding lectin protein. In the present study, we investigated the effects of RTB on inducible nitric oxide (NO) synthase (iNOS), interleukin (IL)-6 and tumor necrosis factor (TNF)-α, as well as the signal transduction mechanisms involved in recombinant RTB-induced macrophage activation. RAW264.7 macrophages were treated with RTB. The results re...
Candida antarctica lipase B (CALB) is one of the most widely used and studied enzymes in the world. In order to achieve the high-level expression of CALB in Pichia, we optimized the codons of CALB gene and α-factor by using a de novo design and synthesis strategy. Through comparative analysis of a series of recombinants with different expression components, we found that the methanol-inducible ...
BACKGROUND Understanding the bioprocess limitations is critical for the efficient design of biocatalysts to facilitate process feasibility and improve process economics. In this study, a proline hydroxylation process with recombinant Escherichia coli expressing L-proline cis-4-hydroxylase (SmP4H) was investigated. The factors that influencing the metabolism of microbial hosts and process econom...
To date there is no commercially-available serodiagnostic for women and men infected with Trichomonas vaginalis. Thirteen epitopes of the immunogenic T. vaginalis α-actinin (106.2-kDa) are detected by sera of women patients, and 5 epitopes, a subset of the 13, are detected by sera of men. A truncated recombinant protein called ACT-P2 (63.5-kDa) encoding the 5 epitopes is used for screening by E...
Post-mortem analyses of brains from patients with Parkinson disease who received fetal mesencephalic transplants show that α-synuclein-containing (α-syn-containing) Lewy bodies gradually appear in grafted neurons. Here, we explored whether intercellular transfer of α-syn from host to graft, followed by seeding of α-syn aggregation in recipient neurons, can contribute to this phenomenon. We asse...
در این تحقیق سنتز و شناسایی پیرازولو پیریدین¬ها و آرن های چند عاملی، از یک واکنش چند جزیی میان دی سیانو آلکن¬ها، هیدرازین و سیانو کیتین دی تیو استال¬ها در دمای 25 درجه سانتیگراد و حلال اتانول انجام شده است. سپس جهت گسترش دامنه تحقیقات، سنتز و شناسایی برخی هتروسیکل¬ها با استفاده از α،α- دی سیانو الفین¬ها (آریل اتیلیدن مالونونیتریل¬ها) مورد بررسی قرار گرفت. در این تحقیق، واکنش سه جزئی شا...
Generation and Functional In Vitro Analysis of Semliki Forest Virus Vectors Encoding TNF-α and IFN-γ
Cytokine gene delivery by viral vectors is a promising novel strategy for cancer immunotherapy. Semliki Forest virus (SFV) has many advantages as a delivery vector, including the ability to (i) induce p53-independent killing of tumor cells via apoptosis, (ii) elicit a type-I interferon (IFN) response, and (iii) express high levels of the transgene. SFV vectors encoding cytokines such as interle...
