The gene encoding the human basic fibroblast growth factor (hbFGF) has been already chemically-synthesized and cloned in pET-3a expression vector (Pasteur Institute of Iran). In the present study, we compared the level of expression of this synthetic hbFGF and its related cDNA in Escherichia coli. The pBR322-cDNA of hbFGF supplied by Dr. Seno (from Molecular Biology Dept, Okaido prefectural uni...
background human preimplantation embryonic cells share many similarities with cancer cells such as ability to self-renew, unlimited proliferation and maintenance of the undifferentiated state. embryo-cancer sequence a (ecsa), also known as developmental pluripotency associated-2 (dppa2), is a cancer testis antigen (cta) with unclear biological function yet. objective: ctas are expressed normall...
Objective(s) Lipocalin 2 (Lcn2) is a 25-kDa glycoprotein that has initially been extracted from neutrophil granules. Expression of Lcn2 is induced under various pathophysiological conditions. It is also known as an early marker of kidney and heart injury. High-level expression of recombinant Lcn2 neutrophil gelatinase-associated(NGAL) in insect cells was the aim of this study. Materials and M...
Background and Aim: Angiogenesis is one of important biological processes any disruption in which leads to disease. The main signaling factor in this process is VEGF which acts through its receptors. The present study was done in order to inhibit the expression of receptor type1of this factor (VEGFR-1) using specific siRNA in the culture medium to use its inhibitory effect on neovascularization...

human granulocyte-colony stimulating factor (hg-csf) cdna was expressed in the methylotrophic yeast pichia pastoris under the control of the alcohol oxidase (aox1) promoter. an expression vector for hg-csf secretion was constructed using vector ppic9. higher levels of hg-csf was obtained using a p. pastoris mut+ (methanol utilization fast) phenotype. the effects of environmental factors such as...
many researchers adopt local binary pattern for pattern analysis. however, the long histogram created by local binary pattern is not suitable for large-scale facial database. this paper presents a simple facial pattern descriptor for facial expression recognition. local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...
knowing the nucleotide sequence of the cholera toxin operon, we designed oligonucleotide primers for its-pcr amplification from local clinical isolates of v. cholerae. the resulting amplification product was cloned in a common puc18 vector. subsequently, a part of this operon encoding the cholera toxin bsubunit (ctb) was reamplified and cloned between the bamh1 and ecor1 sites of the same vecto...
background: the purpose of this study was to clone, express, and purify a novel multidomain fusion protein of micobacterium tuberculosis (mtb) in a prokaryotic system. methods: an hspx/esxs gene construct was synthesized and ligated into a pgh plasmid, e. coli top10 cells were transformed, and the vector was purified. the vector containing the construct and pet-21b (+) plasmid were digested wit...
conclusions the results of the present study will increase our knowledge about molecular cloning and expression of the l. infantum kmp-11 gene, and this may be used as an effective target for controlling visceral leishmaniasis. results the kmp-11 gene was successfully subcloned in pcdna3 as a eukaryotic expression vector. recombinant kmp-11 protein was confirmed by the reverse transcriptase pol...
