Thyroid hormone (T₃) stimulates hepatic lipogenesis by increasing expression of genes, including acetyl-CoA carboxylase and fatty acid synthase. S14 protein, which is thought to be involved in lipid metabolism, appears to respond in parallel. Effects of T₃ on lipogenesis in white and brown adipose tissue are less clear, and may be complicated by indirect effects of the hormone. We developed an adipocytes system where the indirect effects of thyroid hormone are abolished and direct effects of T₃ on lipogenesis could be tested. Fat accumulation was measured by Oil-Red O staining. Insulin clearly enhanced fat accumulation by 2-fold. Isobutylmethylxanthine (IBMX) appeared to inhibit insulin-stimulated fat accumulation. Dexamethasone increased insulin-stimulated fat accumulation about 1.3-fold. Confluent adipocytes were cultured in serum-free medium or medium containing 10% fetal calf serum or 10% fetal calf serum stripped of thyroid hormone and lipogenesis, assessed by the incorporation of ³H₂O, was measured. Medium without serum or supplemented with T₃-depleted serum did not amplify the stimulatory effect or T₃ on lipogenesis compared to medium containing 10% fetal calf serum. Dexamethasone alone led to a decrease in lipogenesis of about 50% in white adipocytes and 25% in brown adipocytes. However, dexamethasone amplified the lipogenic response to T₃ by about 30% in white adipocytes and 60% in brown adipocytes. T₃ (1 μM) stimulated lipogenesis and acetyl-CoA carboxylase and fatty acid synthase mRNA levels up to 2-fold in both types of adipocytes. It seems that these adipocyte systems are a useful model to study the effects of hormones on lipogenic gene expression as well as lipogenesis.
