Reporter genes have proved to be an excellent tool for studying disease progression. Recently, the green fluorescent protein (GFP) ability to quantitatively monitor gene expression has been demonstrated in different organisms. This report describes the use of Leishmania tarentolae (L. tarentolae) expression system (LEXSY) for high and stable levels of GFP(More)
The extract from Artemisia annua, containing artemisinin, has been proven active against multidrug resistant Plasmodium falciparum in previous studies. The purpose of this paper was to study five Artemisia species from Iran for their in vitro and in vivo antimalarial property and detection of artemisinin in the active species by chromatographic and(More)
Methylmercury (MeHg) is the most toxic form of mercury which is bioaccumulated in the aquatic food chain. It has been shown that one of the main targets of MeHg toxicity is the brain, but there is little knowledge of the molecular mechanisms of its toxic effects. In this work we used a proteomics analysis to determine the changes in the brain proteome of(More)
Rabies is a neurotropic virus that causes a life threatening acute viral encephalitis. The complex relationship of rabies virus (RV) with the host leads to its replication and spreading toward the neural network, where viral pathogenic effects appeared as neuronal dysfunction. In order to better understand the molecular basis of this relationship, a(More)
Cell culture feeds optimization is a critical step in process development of pharmaceutical recombinant protein production. Amino acids are the basic supplements of mammalian cell culture feeds with known effect on their growth promotion and productivity. In this study, we reported the implementation of the Plackett-Burman (PB) multifactorial design to(More)
Single-chain variable fragments (scFvs) have recently emerged as attractive candidates in targeted immunotherapy of various malignancies. The anti-CD22 scFv is able to target CD22, on B cell surface and is being considered as a promising molecule in targeted immunotherapy of B cell malignancies. The recombinant anti-CD22 scFv has been successfully expressed(More)
The overexpression of cyclooxygenase-2 (COX-2) enzyme has been strongly contributed to tumorigenesis. The efficacy of celecoxib as a selective COX-2 inhibitor has been shown in many studies, but the underlying mechanism as a chemopreventative agent has not yet been well known. For better understanding the chemopreventative molecular mechanisms, we used a(More)
BACKGROUND Recombinant monoclonal antibodies have been marketed in last three decades as the major therapeutic proteins against different cancers. However choosing a proper medium and supplements to reach the high expression is a challenging step. Despite of commercial serum free and chemically defined media, there are still numerous researches seeking the(More)
Protein-protein interactions studies can greatly increase the amount of structural and functional information pertaining to biologically active molecules and processes. The information obtained from such studies can lead to design and application of new modification in order to obtain a desired bioactivity. Many application packages and servers performing(More)
Prefractionation of complex protein mixtures is an efficient method for increasing the separation power of 2-DE. RP-HPLC has been successfully utilized as a prefractionation method prior to 2-DE. Here we describe the optimization of an efficient RP-HPLC method for prefractionation of baby hamster kidney cell solubilized proteins. A step gradient elution of(More)
