26647830 IDO, through GCN2 kinase activation, downregulates the levels of TCRcomplex tchain and cMyc, resulting in the suppression of Tcell proliferation and a reduction in the levels of LDHA and GLS2

21113813 The results suggest that GCN2 pathways can mediate the limiting effects of Gln deprivation on protein synthesis according to its severity.
20551969 GCN2 and its downstream target, the transcriptional activator ATF4, is critical for proliferation and survival of tumour cells after starvation for amino acids or glucose and is essential for growth in vivo in a xenograft model.
20473272 The authors conclude that the GCN2-eIF2alpha-ATF4 pathway is critical for maintaining metabolic homeostasis in tumour cells, making it a novel and attractive target for anti-tumour approaches.
