the reversal of the thyroxine-induced increase in cerebellar dna synthesis by a prior injection of dibutyryl cyclic amp suggests that the early stimulation of cell division by thyroxine may be mediated by cyclic amp , and that the intracellular balance between cerebellar cyclic amp and cyclic gmp was distorted by in vivo elevation of intracellular cyclic amp levels .
