URI keeps low levels of p53 in a TRIM28-MDM2 dependent manner, maintains SCD1 activity and accumulation of MUFAs, and subsequently promotes resistance to TKIs in cancer cell. URI-p53-SCD1 axis mediates resistance of TKIs and may explain why p53-wild type HCC still showed intrinsic resistance to TKIs...
After transferring the Sub1 Flag plasmid into HL-1 cells, the cells were treated with bleomycin for 24 hours, followed by immunoprecipitation using Flag magnetic beads and protein mass spectrometry.
