Chinese hamster ovary (CHO) cells cultured in vitro were continuously exposed to increasing concentrations of diethylmaleate (DEM). Chronic exposure of these cells (designated CHO/DEM) to 80 microM diethylmaleate resulted in an increase in cystine transport, a decrease in glutathione inhibition of the enzyme gamma-glutamylcysteine synthetase, elevation of intracellular glutathione levels to 4.3...

Choline (Cho)-containing phospholipids are the most abundant phospholipids in cellular membranes and play fundamental structural as well as regulatory roles in cell metabolism and signaling. Although much is known about the biochemistry and metabolism of Cho phospholipids, their cell biology has remained obscure, due to the lack of methods for their direct microscopic visualization in cells. We...

Background Chromosomal instability, which often occurs as a random event in an uncontrollable manner, is a key characteristic of Chinese Hamster Ovary (CHO) cells. This often complicates the process of establishing stable, high antibody-producing CHO cell lines. We previously found that the abnormal increase of chromosome number is linked to increased antibody production in adherent CHO DG44 ce...

background toxoplasmosis is an opportunistic protozoan infection with a high prevalence in a broad range of hosts infecting up to one-third of the world human population. toxoplasmosis leads to serious medical problems in immunocompromised individuals and fetuses and also induces abortion and mortality in domestic animals. therefore, there is a huge demand for the development of an effective va...

The induction of cytotoxicity and DNA single-strand breaks by chromium(VI), cadmium(II), and mercury(II) were compared in H2O2-resistant Chinese hamster ovary (CHO(R)) cells and parental (CHO(P)) cells. Using a colony-forming assay, CHO(R) cells were found to be significantly more resistant than CHO(P) cells to the cytotoxicity caused by CdCl2 and HgCl2, but not to that caused by Na2CrO4. Howev...

Chinese hamster ovarian cells (CHO) cells have been extensively utilized for industrial production of biopharmaceutical products, such as monoclonal antibodies, human growth hormones, cytokines, and blood-products. Recent advances in recombinant DNA technology have resulted in the bioengineering of CHO cells that have robust gene amplification systems and can also be adapted to grow in suspensi...

IRS-1 is a major insulin receptor substrate which may play an important role in insulin signal transmission. The mRNA for IRS-1 in rat cells and tissues is about 9.5 kilobases (kb). Rat liver IRS-1 was stably expressed in Chinese hamster ovary (CHO) cells (CHO/IRS-1). Although its calculated molecular mass is 131 kDa, IRS-1 from quiescent cells migrated between 165 and 170 kDa during sodium dod...

Mitomycin c (MMC), a quinone-containing anticancer drug, is known to redox cycle and generate reactive oxygen species. A key enzyme mediating MMC redox cycling is cytochrome P450 reductase, a microsomal NADPH-dependent flavoenzyme. In the present studies, Chinese hamster ovary (CHO) cells overexpressing this enzyme (CHO-OR cells) and corresponding control cells (CHO-WT cells) were used to inves...

Chinese hamster ovary (CHO) cells, first isolated in 1957, are the preferred production host for many therapeutic proteins. Although genetic heterogeneity among CHO cell lines has been well documented, a systematic, nucleotide-resolution characterization of their genotypic differences has been stymied by the lack of a unifying genomic resource for CHO cells. Here we report a 2.4-Gb draft genome...
