HEK293T cells were transfected and anti-FLAG M2 magnetic beads (Sigma, M8823, United States; 50 μl/sample) were used for immunoprecipitation including rabbit anti-MDM2, rabbit anti-p53, rabbit anti-FXR, and rabbit anti-ubiquitin (Supplementary Table 7).

In another assay, the supernatants of Lenti-FXR CaSki cells were incubated with 2 μg IgG or mouse anti-SHP (Santa Cruz, CA, United States). The mixture was incubated with protein G-Agarose beads (Roche, United States) and the samples were assessed by western blot.

Details are shown in the Supplementary Materials.
