Effects of cyclic AMP on S-100 protein level in C-6 glioma cells
Abstract:
Dibutyryl cyclic AMP (dbcAMP) markedly elevated S-100 protein level in C-6 glioma cells in vitro. Quantitative analysis by two-dimensional polyacrylamide gel electrophoresis revealed that the elevation was caused by a combination of increased synthesis and reduced degradation of S-100 protein in C-6 cells exposed to dbcAMP. These results suggest that dbcAMP affects both the synthesis and the degradation of S-100 protein in C-6 cells.
