Product Data:
Biological target: L-LEUCINE-13C6, also known as 13C6-D-Leucine or L-Leucine-1,2,3,4,5,5'-13C6, is a fully 13C labelled D-Leucine.
In vitro activity: On the other hand, Leu (L-leucine) treatment sharply decreased the β-cell number, as measured by insulin immunostaining (Fig. 2B and C for quantification). Such data indicate that l-Leu treatment represses β-cell development. Reference: Diabetes. 2012 Feb;61(2):409-17. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3266409/
In vivo activity: This study has explored the hypothesis that reduced ribosome function contributes to RBS in zebrafish models and human cells. To study this cohesinopathy in a whole animal model this study used ESCO2-mutant and morphant zebrafish embryos, which have developmental defects mimicking RBS. Stimulation of the TOR pathway with L-leucine rescued many developmental defects of ESCO2-mutant embryos. Reference: PLoS Genet. 2013;9(10):e1003857. https://pubmed.ncbi.nlm.nih.gov/24098154/
