For Caco‐2, SW480 and SW620 CRC cell lines, glutamine depletion did not affect mTORC1 activity in a dose‐response experiment, as determined by the phosphorylation state of downstream target 4E‐BP1, and only variably reduced S6 phosphorylation (Figure S3a–d). This evidence concerns the gene EIF4EBP1 and colorectal carcinoma.
