The mTORC1/4E-BP pathway coordinates hemoglobin production with L-leucine availability.
Boston, United States. In Sci Signal, Dec 2014
Inadequate NEAA uptake by pharmacologic inhibition or RNAi-mediated knockdown of LAT3 triggered a specific reduction in hemoglobin production in zebrafish embryos and murine erythroid cells through the mTORC1 (mammalian target of rapamycin complex 1)/4E-BP (eukaryotic translation initiation factor 4E-binding protein) pathway.
Glutaminolysis activates Rag-mTORC1 signaling.
Basel, Switzerland. In Mol Cell, 2012
We demonstrate that glutamine in combination with leucine activates mammalian TORC1 (mTORC1) by enhancing glutaminolysis and alpha-ketoglutarate production.
