Cells were treated with increasing concentrations of LYMTAC-2 for 24 h and HiBiT levels were measured using Nano-Glo® HiBiT lytic reagent. Data are representative of two independent experiments and reported as the mean ± S.E. E) HCT116 (HF-KRAS) cells stably expressing FLAG-MTH1-LAPTM5 were pre-treated with BafA1, 2 BTZ, or TAK-243 for 30 min followed by co-treatment with DMSO or 500 nM LYMTAC-2 for 6 h and subjected to immunoblotting with KRAS and tubulin antibodies. Data are representative of two independent experiments. F) KRAS ubiquitylation assay. HA-ubiquitin was transfected into HCT116 expressing FLAG-MTH1-LAPTM5, which were pre-treated with 200 nM BafA1 for 30 min followed by co-treatment with DMSO or 1 µM LYMTAC-2 treatment for 4 h. Next, cells were lysed and subjected to immunoprecipitation with anti-HiBiT antibody. Whole cell lysate was used as INPUT. The respective blots were probed with HA, MTH1, HiBiT, and vinculin antibodies. Data are representative of two independent experiments. G) AsPC-1 cells stably expressing FLAG-MTH1-LAPTM4a were pre-treated with either pan-KRAS inhibitor or MTH1 ligand, followed by DMSO or 100 nM LYMTAC-4 treatment for 6 h. Cells were lysed and subjected to immunoblotting with KRAS, pERK, and tubulin antibodies. Data are representative of two independent experiments.
