with advent and development of dna recombinant technology and advantages of p. pastoris expression system, fusion (f) protein of pprv expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against ppr disease. in this study, f gene of pprv nigeria 75/1 strain (1637 bp) was amplified using rt-pcr and purified. it was then clon...

Background: Chlamydomonas reinhardtii is a novel recombinant eukaryotic expression system with many advantages including fast growth rate, rapid scalability, absence of human pathogens and the ability to fold and assemble complex proteins accurately, however, obstacle relatively low expression level necessitates optimizing foreign gene expression in this system. The Green Fluorescent Protein (G...

background the fas receptor/ligand system including soluble forms is the most important apoptotic initiator in the liver. dysregulation of this pathway may contribute to abnormal cell proliferation and cell death and is regarded as one of the mechanisms preventing the immune system from rejecting the tumor cells. objectives to analyze the role of fas system fas/ fas ligand (fas/ fasl) in the mu...

background: the poor permeability of the plasma and nuclear membranes to dna plasmids are two major barriers for the development of these therapeutic molecules. therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. objectives: the aim of this study was to investigate the in vitro delivery of plasmid dna encoding hpv16 e7 gene ...

Background: The expression of bio-therapeutic proteins in mammalian cells, such as CHO, attains high homogeneity related to post-translational modifications. Although CHO remains the most popular cell line for bestselling biotherapeutic proteins on the market, there are still drawbacks such as expensive culture media, long time line, and high drug cost. Recently, researches on a novel Leishmani...

Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...

noncoding ribonucleic acids micro-rna is involved in the regulation of gene expression have major roles in the post-transcriptional level. a micro-rna alone several causes down regulation of mrna transcript of the target. thus, small changes in the expression of a micro rna may lead to significant changes in gene expression are different. micro- rna as key regulators of immune cell lineage diff...

Background: Ovine follicle stimulation hormone (OFSH) is a pituitary glycoprotein and belongs to the family of glycoprotein hormones. This hormone plays a key role in the function of the reproductive system: it is essential for sertoli cell function and spermatogenesis in testis and it stimulates the growth of ovulatory follicles in females. Ovine FSH hormone is a heterodimeric hormone consisti...
