The activity of liver 6-phosphofructo-2-kinase (PFK-2), the enzyme that catalyses the synthesis of fructose 2,6-bisphosphate, was markedly decreased in hypothyroid rats and partially restored after 3 days of treatment with triiodothyronine. The changes in PFK-2 activity were accompanied by parallel changes in enzyme content measured by immunotitration and in PFK-2 mRNA determined by dot blot and Northern blot hybridization with cDNA probes. It is concluded that thyroid hormone stimulates liver PFK-2 gene expression by a pre-translational mechanism.
