Anucleate HTC cells have been used to determine the importance of the nucleus in the regulation of the intracellular levels of tyrosine aminotransferase (TAT) in hepatoma tissue culture (HTC) cells. In the absence of the nucleus, neither the induction of the enzyme by dexamethasone nor its deinducti
## 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
We investigated the relationship between the expression of tyrosine aminotransferase (TAT) and cytoskeletal systems of cultured rat hepatocytes by using serumfree culture conditions and changing three factors: 1) the concentration of calcium, 2) the dish-coating material, and 3) the cell-plating den
## Hamburg (D P ), Federal Republic of Germany Tyrosine-aminotransferase (TAT) is encoded by a liver-specific gene known to be expressed perinatally. Fetal rat hepatocytes (gestation day 19) in primary cultures, in which TAT gene expression is normally undetectable, are induced by hydrocortisone t
