title: [Possible approaches to an analysis of the heterogeneous response of the transcription complex to cholinergic actions].
abstract: The accumulation of tyrosine-aminotransferase (TAT) as a marker of the individual gene activation was studied in the rat tissue after the administration of cholinomimetics and cholinolytics in order to elucidate the relations between cholinoreceptor functional state and the genetic apparatus. The regulation of TAT synthesis was found to be controlled by both cholinomimetic concentration and the density of cholinoreceptors in hepatocytes. Transsynaptic regulation of TAT activity was shown to be different in the brain and liver. It is suggested that the approaches discussed might be useful for the analysis of the relationship between cholinoreceptor state and the regulation of biochemical functions of target cells.
