title: [Effect of catecholamines and serotonin on RNA-synthesizing activity in isolated nuclei and chromatin of the rat brain and liver].
abstract: It has been shown that intraperitoneal injections of L-DOPA cause an increase in the matrix activity of chromatin and stimulate the incorporation of [3H]uridine into the nuclear fraction of rat brain cells by 35%. In vitro studies have shown that preincubation of brain chromatin with L-DOPA diminishes the inhibiting effect of actinomycin D on RNA synthesis. It has been found that the rate of RNA synthesis in vitro depends on concentrations of catecholamines (L-DOPA, dopamine, norepinephrine) and serotonin.
