  • DNA fragmentation is a hallmark of apoptosis that occurs in a variety of cell types; however, it remains unclear whether caspase-3 is required for its induction. To investigate this, we produced caspase-3 knockout Chinese hamster ovary (CHO)-K1 cells and examined the effects of gene knockout and treatment with caspase-3 inhibitors.

  • Food can be defined as the nutritive material taken into an organism for growth, work, or repair and for maintaining the vital processes. Food sustains life, and, as such, many individuals view food as an uncomplicated, pure source of nutrition. Therefore, such individuals are often bewildered to learn that food is comprised of an array of natural chemicals, and not all the chemicals are nutrients or enhance nutritive value, but in fact may decrease nutritional value or, worse still, are toxic (e.g., naturally occurring toxicants).

  • GM-CSF is one of several naturally occurring glycoproteins that regulate leukocyte production, migration and function. It has been produced in different cell types, with different properties that depend on the production process used. The purpose of this work was to characterize the recombinant human GM-CSF from an engineered Chinese hamster ovary cell line grown in suspension and as adherent culture for the identification of the glycosylation sites and the defi-nition of the glycosidic moiety, including the degree of site occupancy....

  • We examined the effect of suboptimal concentrations of cyclin-dependent kinase inhibitors, which do not interfere with cell proliferation, on retinoblastoma expression in hamster (Chinese hamster ovaryK1) and human (K562 and HeLa) cells. To achieve this, we used the chemical inhibitors roscovitine and olomoucine (which inhibit CDK2 prefer-entially),UCN-01 (which also inhibits CDK4/6) andp21 (as an intrinsic inhibitor). All chemical inhibitors and over-expression of p21 strongly induced retinoblastoma protein expression.

  • The structure of post-translational modifications of human heparin cofactor II isolated from human serum and from recombinant Chinese hamster ovary cells and their effects on heparin binding have been characterized. Oligosaccharide chains were found attached to all three potential N-glycosylation sites in both protein preparations. The carbohydrate structures of heparin cofactor II circulating in blood are complex-type diantennary and triantennary chains in a ratio of 6 : 1 with the galactose being 90% sialylated with a2 fi 6 linked N-acetylneuraminic acid....

  • Although highly conserved throughout evolution, the exact biological function of the prion protein is still unclear. In an effort to identify the potential biological functions of the prion protein we conducted a small-molecule screening assay using the Syrian hamster prion protein [shPrP(90– 232)].

  • Apurinic⁄apyrimidinic endonuclease (APE), an essential DNA repair enzyme, initiates the base excision repair pathway by creating a nick 5¢ to an abasic site in double-stranded DNA. Although the Chinese hamster ovary cells remain an important model for DNA repair studies, the Chinese hamster APE (chAPE1) has not been studied in vitro in respect to its kinetic characteristics.

  • Modern biotechnology is often associated with the use of genetically altered microorganisms such as E. coli or yeast for the production of substances like synthetic insulin or antibiotics. It can also refer to transgenic animals or transgenic plants, such as Bt corn. Genetically altered mammalian cells, such as Chinese Hamster Ovary cells (CHO), are also used to manufacture certain pharmaceuticals. Another promising new biotechnology application is the development of plant-made pharmaceuticals.

  • The cloned guinea-pig Y2 neuropeptide Y (NPY) receptors expressed in Chinese hamster ovary (CHO) cells, as well as the Y2 receptors natively expressed in rat forebrain, are distributed in two populations. A smaller population that is readily accessed by agonist peptides on the surface of intact cells constitutes less than 30% of Y2 receptors detected in particulates after cell homogenization. A much larger fraction of cell surface Y2 sites can be activated by sulfhydryl modifiers.
