This PDF file includes:

  • Fig. S1. Lower copy number of genomic ARD1 was found in ARD1 LOH group.
  • Fig. S2. Endogenous ARD1 in five cell lines with low ARD1 abundance and five cell lines with high ARD1 abundance.
  • Fig. S3. Myc-ARD1 had a stronger growth-inhibitory effect in tumor cells with lower endogenous ARD1 than in cells with abundant endogenous ARD1.
  • Fig. S4. Knockdown of ARD1 with either of two different siRNAs increased the growth of MDA-MB-435 cells.
  • Fig. S5. ARD1 reduced the degree of pS6K1(T389) whereas depletion of ARD1 increased pS6K1(T389) under conditions of both serum starvation and insulin-like growth factor (IGF) stimulation.
  • Fig. S6. ARD1 reduced p4EBP1(S65) under conditions of both serum starvation and IGF stimulation.
  • Fig. S7. Transient transfection of Myc-ARD1 increased the amount of TSC2 in HEK293T cells.
  • Fig. S8. Depletion of ARD1 decreased the stability of TSC2.
  • Fig. S9. The data of Fig. 6B on a semilog plot.
  • Fig. S10. Treatment of MG132 increased TSC2 abundance.
  • Fig. S11. Schematic shows wild-type (WT) ARD1 and three truncated forms of ARD1.
  • Fig. S12. WT ARD1, but not ARD1 ΔC, increased the stability of TSC2.
  • Fig. S13. WT ARD1, but not ARD1 AA or ARD1 ΔAT, stabilized TSC2.
  • Fig. S14. WT ARD1, but not ARD1 AA or ARD1 ΔAT, reduced ubiquitination of TSC2.
  • Fig. S15. WT ARD1, but not ARD1 AA or ARD1 ΔAT, significantly suppressed the growth of MDA-MB-435 and MCF-7 cells.
  • Fig. S16. Depletion of ARD1 decreased the acetylation of endogenous TSC2.
  • Fig. S17. We detected no ARD1-induced ε-acetylation of TSC2.
  • Fig. S18. Shown are two representative breast cancer specimens with consecutive sections.
  • Fig. S19. Representative images of ARD1 and TSC2 abundance in four different types of cancers.
  • Table S1. Relationship between ARD1 and TSC2 in surgical specimens of various tumors.
