The hormone fi broblast growth factor 21 (FGF21), which is critical to the adaptive metabolic response to starvation, is also induced under amino acid deprivation. Upon leucine deprivation, we found that FGF21 is needed to repress expression of lipogenic genes in liver and white adipose tissue, and stimulate phosphorylation of hormone-sensitive lipase in white adipose tissue. The increased expression of Ucp1 in brown adipose tissue under these circumstances is also impaired in FGF21- defi cient mice. Our results demonstrate the important role of FGF21 in the regulation of lipid metabolism during amino acid starvation. ¿De Sousa-Coelho, A. L., J. Relat, E. Hondares, A. Pérez-Martí, F. Ribas, F.
