In EJ28Luc bladder cancer cells, incubation with 213Bi-anti-EGFR-MAb resulted in a significant decrease of overall 13C-incorporation into alanine (3.9% vs 4.5% in controls), into serine (2.9% vs 3.4% in controls), into glutamate (2.7% vs 2.9% in controls), and into aspartate (1.9% vs 2.4% in controls) (Fig. 1, red arrows; Fig. 2A). Here, EGFR is linked to urinary bladder cancer.
