Type 1 transforming growth factor beta: amplified expression and secretion of mature and precursor polypeptides in Chinese hamster ovary cells.

Purchio, A F; Brunner, A M; Gentry, L E; Lim, G J; Webb, N R; Ranchalis, J E; Marquardt, H; Twardzik, D R; Lioubin, M N

Recombinant type 1 transforming growth factor beta (TGF-beta) was expressed to high levels in CHO cells by using dihydrofolate reductase (dhfr) gene amplification. The expression plasmid was derived from the pSV2 vectors and contained, in tandem, the simian TGF-beta and mouse dhfr cDNAs. Transcripti...

TNFalpha-Polymorphismus bei Patienten mit Sepsis und Schilddrüsenkarzinomen

Rossbach, Christiane

Das Zytokin Tumornekrosefaktor a (TNFa) hat einen entscheidenden Anteil an der Entwicklung schwerer Komplikationen, wie septischer Schock und Multiorganversagen nach Entwicklung einer Sepsis. Eine Assoziation des TNF2-Allels mit einem erhöhten TNF a Spiegel und einer höheren Mortalitätsrate wurde i...

Recombinant type 1 transforming growth factor beta precursor produced in Chinese hamster ovary cells is glycosylated and phosphorylated.

Purchio, A F; Brunner, A M; Cooper, J A; Gentry, L E

Analyses of cDNA clones coding for simian type 1 transforming growth factor beta (TGF-beta 1) suggest that there are three potential sites for N-linked glycosylation located in the amino terminus of the precursor region. Analysis of [3H]glucosamine-labeled serum-free supernatants from a line of Chin...

Next-nucleotide effects in mutations driven by DNA precursor pool imbalances at the aprt locus of Chinese hamster ovary cells.

Phear, G; Meuth, M; Nalbantoglu, J

Imbalances of the intracellular pools of the precursors of DNA synthesis, the deoxyribonucleoside triphosphates, produce marked shifts in the spectrum of mutations at the aprt locus of Chinese hamster ovary cells. Mutations induced by excess dTTP or dCTP are dominated by misincorporation of the nucl...
