Abstract

The effects of adrenalectomy, hydrocortisone and actinomycin D on the cytoplasmic (c-), mitochondrial (m-) and nuclear (n-) tyrosine aminotransferase (TAT) isoenzymes of the liver of immature (6-) and adult (35-week) male albino rats were studied. Adrenalectomy stimulates the activity of nTAT in adult rats. The activities of mTAT of immature, and of c- and mTAT of adult rats are inhibited by adrenalectomy. Hydrocortisone induces and actinomycin D inhibits the induction of the isoenzymes in adrenalectomized rats of both ages. However, the induction and inhibition are more pronounced in the adult than in the immature.
