## Abstract Theophylline, a cyclic nucleotide phosphodiesterase inhibitor, increases the rate of tyrosine aminotransferase (TAT) degradation in rat hepatoma tissue culture (HTC) cells. Theophylline (0.1β10 mM) causes a twoβ to fiveβfold increase in intracellular cAMP concentration but a 30β60% decr

## Abstract The role of the nucleus in bringing about the induction of tyrosine aminotransferase (TAT) by glucocorticosteroid hormone and its deinduction upon steroid removal has been studied in enucleated rat hepatoma tissue culture cells (FU5β5). Both processes require the presence of the nucleus
## Abstract The increase in tyrosine aminotransferase activity which occurs in rat hepatoma tissue culture (HTC) cells in response to cyclic AMP analogs has been shown to be an enzyme induction, similar to the larger response observed in certain other hepatoma cells and in liver. A specific antibod
