title: Catecholamines increase nerve growth factor mRNA content in both mouse astroglial cells and fibroblast cells.
abstract: Previous studies have shown that catecholamines increase the nerve growth factor (NGF) content in medium conditioned by mouse L-M fibroblast cells and mouse astroglial cells. In this study, the NGF mRNA levels in these cells were measured by Northern blot analysis. In astroglial cells treated with epinephrine (EN), the cellular NGF mRNA level increased prior to accumulation of NGF in the culture medium. 3-Hydroxytyramine (DA) and norepinephrine (NE) also increased the cellular NGF mRNA content. An increased level of NGF mRNA elicited by EN was also observed in mouse L-M cells. These results indicate that catecholamines enhance NGF synthesis of L-M fibroblast cells and astroglial cells by increasing the cellular content of NGF mRNA. The present results also indicate that the effects of catecholamines are not mediated by adrenergic receptors.
