Background Follicle stimulating hormone (FSH)- a hetrodimeric glycoprotein- is secreted by pituitary gland. This hormone stimulates growth and maturation of the follicles in females and sperms in male. Up to now, glycoprotein hormones such as FSH have produced in different cell lines. Among of the mammalian expression systems, the Chinese hamster ovary cells (CHO) have taken into consideration ...

We have created a genome-scale network reconstruction of chinese hamster ovary (CHO) cell metabolism. Existing reconstructions were improved in terms of annotation standards, to facilitate their subsequent use in dynamic modelling. The resultant network is available from ChoNet (http://cho.sf.net/).

Chinese hamster Ovary (CHO) cell lines are the dominant industrial workhorses for therapeutic recombinant protein production. The availability of genome sequence of Chinese hamster and CHO cells will spur further genome and RNA sequencing of producing cell lines. However, the mammalian genomes assembled using shot-gun sequencing data still contain regions of uncertain quality due to assembly er...

The Welgevonden stock of Ehrlichia ruminantium, aetiological agent of heartwater, was propagated in baby hamster kidney (BHK) cells, Chinese hamster ovary (CHO-K1) cells and Madin Darby bovine kidney (MDBK) cells. The cultures required supplementation of the medium with cycloheximide for reliable growth of E. ruminantium. Growth of the Welgevonden stock in BHK and CHO-K1 cells could lead to the...

Whole-cell pertussis vaccine (wP) has been imperative and highly effective in preventing childhood deaths due to pertussis. Pertussis toxin is one of the virulence factors of Bordetella pertussis in all available pertussis vaccines. wP production in Razi Vaccine and Serum Research Institute is according to bioreactor culture of B. pertussis strains in B2 medium. The aim ...

Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a  chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...

Mammalian cell expression systems are the dominant tool today for producing complex biotherapeutic proteins. In this chapter, we discuss the basis for this dominance, and further explore why the Chinese hamster ovary (CHO) cell line has become the prevalent choice of hosts to produce most recombinant biologics. Furthermore, we explore some of the innovations that are currently in development to...

The understanding of the nutritional requirements for Chinese hamster ovary (CHO) cells and other immortalized cell lines was an early milestone in developing cell culture media. A key aspect of these early studies was defining those amino acids termed ‘essential’ for survival and growth of different cell lines. However, the amino acids essential for growth of cells in culture differ from those...

Dopamine and to a much greater extent, 6-hydroxydopamine reduced the growth of the mouse neuroblastoma cell population in vitro but did not induce morphological differentiation. The growth inhibition at a lower drug concentration was primarily due to inhibition of cell multiplication, which was reversible. L-Dopa, norepinephrine, epinephrine, 3,4-dihydroxyphenylacetic acid, or homovanillic acid...
