Sustaining a role of GS in Notch1‐dependent glutamine addiction, we also observed that Notch1‐negative T‐ALL cells (H33HJ‐JA1) presented a significant induction of GS at the protein level during glutamine restriction, not observed in Notch1‐positive T‐ALL cells (CUTLL1) (Fig. 6D‐F). The gene discussed is NOTCH1; the disease is acute lymphoblastic leukemia.
