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...
Mammalian cells dominate the biopharmaceutical industry and maintaining cell viability is a limiting factor in most mammalian cell cultures. This project is focused on developing an online (in-situ) dielectric spectroscopy sensor that is capable of measuring cell viability in real-time to enable optimization of culture conditions for Chinese Hamster Ovary (CHO) cell lines in micro-bioreactors.
Angiotensin-(1-7) [Ang-(1-7)] causes endothelial-dependent vasodilation mediated, in part, by NO release. However, the molecular mechanisms involved in endothelial NO synthase (eNOS) activation by Ang-(1-7) remain unknown. Using Chinese hamster ovary cells stably transfected with Mas cDNA (Chinese hamster ovary-Mas), we evaluated the underlying mechanisms related to receptor Mas-mediated posttr...
For the first time, a patient with asymptomatic QT interval prolongation was found to carry missense mutation c.277G>A (p.Val93Ile) in KCNJ2 gene, described previously only as cause of familial form atrial fibrillation. The corresponding amino acid substitution introduced into plasmid encoding Kir2.1 channel and mutant gene expressed Chinese hamster ovary cells (CHO-K1) evaluate effect on IK1 c...
Alphaviruses, such as Semliki Forest virus, normally enter cells by penetration from acidic organelles of the endocytic pathway. The virions are internalised intact from the cell surface before undergoing acid-induced fusion in endosomes. To investigate the possibility that endocytosis might play a role in delivering virions to specific sites for replication, we compared SFV infection of baby h...
OBJECTIVE We aimed to assess the therapeutic efficacy of differentially modified soluble receptor for advanced glycation end products (sRAGE) in vivo using vessel ultrasound sonography and to compare the sonography data with those from postmortem histomorphologic analyses to have a practical reference for future clinical applications. METHODS Vessel ultrasound sonography was performed in a sR...
The mutational specificity of the alkylating agent 1-3-bis-(2-chloroethyl)-1-nitrosourea (BCNU) was analyzed at the endogenous hemizygous adenine phosphoribosyl transferase gene of the Chinese hamster ovary cell line D422. A 1-h treatment of the Chinese hamster ovary cells with 50 microM BCNU resulted in a toxicity level of 62% and induced mutation at this target with a frequency of 32.1 mutant...
The mutational specificity of the alkylating agent l-3-bis-(2-chloroethyl)-l-nitrosourea (BCNU) »as analyzed at the endogenous hemizygous (alenine phosphoribosyl transferase gene of the Chinese hamster ovary cell line D422. A 1-h treatment of the Chinese hamster ovary cells with 50 UM BCNU resulted in a toxicity level of 62% and induced mutation at this target with a frequency of 32.1 mutants/...
