ATM and colonic neoplasm: Similar to ATM KD, we found that Gal-9 levels were substantially enhanced in response to ATM inhibition (ATMi) in H157 and A549 human non-small cell lung cancer (NSCLC) cells, MDA-MB-231 human triple-negative breast cancer (TNBC) cells, B16-F10 murine melanoma cells, LLC murine lung tumor cells, CT26 and MC-38 murine colon tumor cells (Fig. 2C-D, Fig. S2A).
