Expression of the biologically active beta-subunit of mouse nerve growth factor (beta-NGF) was conferred onto cultured AtT-20 mouse pituitary cells via a replication-defective retroviral vector. The retroviral LTR promoter was used for expression of a cDNA for beta-NGF corresponding to the shorter mRNA species produced by most tissues that receive(More)
The effects of nitric oxide (NO) synthase inhibitors on the electrically evoked release of [3H]acetylcho-line were studied in guinea-pig myenteric plexus preparations preincubated with [3H]choline. NG-monomethyl-l-arginine (EC50 5.3 μmol l−1) and NG-nitro-l-arginine (EC50 1.3 μmol l−1) concentration-dependently increased the evoked release of(More)
Oligosaccharide processing is controlled by host- and protein-dependent factors. To increase our understanding of the relative contribution of those factors we studied the glycosylation of yeast invertase expressed in a heterologous system. Invertase synthesized in psi-2 cells (an NIH 3T3-derived packaging line) is secreted efficiently, enzymatically(More)
Starting point for the present work was the assumption that the cell line MuMac-E8 represents a murine cell population with stem cell properties. Preliminary studies already pointed to the expression of stem-cell associated markers and a self-regenerative potential of the cells. The cell line MuMac-E8 should be examined for their differential stage within(More)
