Abstract
The effects of thyroid hormone on cholesterol 7 alpha hydroxylase, LDL receptor, HMG-CoA reductase, apo A-I and farnesyl pyrophosphate synthetase hepatic mRNA levels were investigated in hypophysectomized rats. Of these mRNAs cholesterol 7 alpha hydroxylase responded the most rapidly and required the lowest dose of T3. Maximal mRNA levels were reached one hr after T3 administration and required 10 micrograms/100g of body weight. These results suggest that the hypocholesterolemic effect of thyroid hormone may be mediated by a primary effect on cholesterol 7 alpha hydroxylase gene expression.Entities:
