Nerve growth factor affects cyclic AMP metabolism, but not by directly stimulating adenylate cyclase activity. Academic Article uri icon

Overview

abstract

  • Published experiments both support and contradict the hypothesis that nerve growth factor (NGF) can regulate adenylate cyclase activity. Using a sensitive assay that measures the conversion of [2-3H]adenine to [3H]cyclic AMP, we have shown that NGF alone cannot measurably stimulate cyclic AMP production, whereas the adenosine analog phenylisopropyladenosine (PIA) stimulates adenylate cyclase 20-fold over basal activity. NGF potentiates the capacity of both PIA and cholera toxin to stimulate cyclic AMP accumulation at all concentrations tested. This potentiation occurs at the earliest measurable times and does not require RNA synthesis. Therefore, we conclude that cyclase activation alone does not account for the effect of NGF on cyclic AMP accumulation and we discuss possible mechanisms.
