Leucine 168-175 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Homo sapiens 133-138 18806097-5 2008 AICAR decreased basal in vivo muscle (gastrocnemius) protein synthesis and completely prevented the leucine-induced increase, independent of a change in muscle adenine nucleotide concentration. Leucine 100-107 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Homo sapiens 0-5 18806097-6 2008 AICAR also prevented the hyperphosphorylation of eukaryotic initiation factor (eIF) 4E binding protein (4E-BP1), ribosomal protein S6 kinase (S6K1), S6, and eIF4G in response to leucine, suggesting a decrease in mTOR activity. Leucine 178-185 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Homo sapiens 0-5 18806097-7 2008 Moreover, AICAR prevented the leucine-induced redistribution of eIF4E from the inactive eIF4E.4E-BP1 to the active eIF4E.eIF4G complex. Leucine 30-37 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Homo sapiens 10-15 18806097-9 2008 However, the inhibitory actions of AICAR were associated with reduced phosphorylation of proline-rich Akt substrate-40 and increased phosphorylation of raptor, which represent potential mechanisms by which AICAR might be expected to inhibit leucine-induced increases in mTOR activity and protein synthesis under in vivo conditions. Leucine 241-248 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Homo sapiens 35-40 18806097-9 2008 However, the inhibitory actions of AICAR were associated with reduced phosphorylation of proline-rich Akt substrate-40 and increased phosphorylation of raptor, which represent potential mechanisms by which AICAR might be expected to inhibit leucine-induced increases in mTOR activity and protein synthesis under in vivo conditions.
