Treatment of primary cultures of adult rat hepatocytes with 5 mmbutyrate inhibited the spontaneous decrease in basal activity and mRNA levels of tyrosine aminotransferase (TAT) that occurred during culture (Staeckeret al., submitted). We report here that butyrate treatment of primary cultures of rat hepatocytes initially inhibited the induction of TAT. This inhibition was followed by a period of accelerated TAT induction. TAT induction in butyrate-treated primary cultures of adult rat hepatocytes occurred only after metabolism of butyrate by the cultured hepatocytes. The accelerated induction of TAT in hepatocyte cultures treated with sodium butyrate was reflected by increased TAT activity and mRNA levels. Cultured hepatocytes rapidly metabolized butyrate, but the addition of more butyrate into cultures after its initial metabolism resulted in a rapid reduction in TAT activity. These findings indicate that butyrate treatment can affect the expression of TAT in primary hepatocyte cultures in both a positive (increased basal TAT expression) and a negative (inhibition of the induced expression of TAT) manner.
