L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.

体外研究(In Vitro)
L-Leucine (10 mM) treatment impairs endocrine progenitor cell development.In E13.5 rat pancreatic explants, in absence of added L-Leucine, Ngn3 mRNA levels increased after 1 day of culture, peaked on day 3, and then decreased. When L-Leucine is added, a dramatic decrease is observed in Ngn3 mRNA levels. This decrease in Ngn3 mRNA levels was paralleled by a decrease in the number of Ngn3-expressing cells (4728±408 vs. 959±28; P<0.01). Finally, L-Leucine also caused a dose-dependent repressive effect on the mRNA levels of the three genes, namely Ngn3, its target Insm1, and insulin. Leucine stimulates protein synthesis in skeletal muscle of neonatal pigs by enhancing mTORC1 activation. L-Leucine increases intracellular HIF-1α levels and activates the HIF-1α signaling pathway, and these two effects are mediated by the mTOR signaling pathway
体内研究(In Vivo)
L-Leucine (24 g/kg diet) combined with Resveratrol (12.5 mg/kg diet) to diet-induced obese (DIO) mice increases adipose Sirt1 activity. Combination results in significant reductions in body weight, weight gain, visceral adipose tissue mass, fat oxidation and heat production in mice.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
