1 For example, during amino acid limitations, ATF4 in the amino acid response induces expression of asparagine synthetase (ASNS), which provides for asparagine biosynthesis. Asparagine asparagine synthetase (glutamine-hydrolyzing) Homo sapiens
2 Here we show that DNA hypermethylation at the ASNS promoter prevents its transcriptional expression following asparagine depletion. Asparagine asparagine synthetase (glutamine-hydrolyzing) Homo sapiens
3 We conclude that chromatin accessibility is critical for ATF4 activity at the ASNS promoter, which can switch ALL cells from an ATF4-dependent adaptive response to ATF4-independent apoptosis during asparagine depletion. Asparagine asparagine synthetase (glutamine-hydrolyzing) Homo sapiens
