Supplementary Materials (PDF File)

  • Materials and Methods
  • Fig. S1. Analysis of the Hedgehog kinome siRNA screen.
  • Fig. S2. Candidate hits are specific to Hh signaling.
  • Fig. S3. Pooled siRNAs do not affect the SV40 luciferase reporter stably transfected in CH310T1/2 cells.
  • Fig. S4. Cotransfection of siRNAs to candidate genes and Gli3 indicate that all nine candidates act upstream of Gli3 in S12 cells since none repressed luciferase activity induction by Gli3 in the absence of Hh.
  • Fig. S5. Effect of siRNA knockdown of candidates on ciliogenesis.
  • Fig. S6. Nek1 and Prkra affect ciliogenesis.
  • Fig. S7. Candidate hits are not transcriptionally regulated by the Hh pathway in S12 cells.
  • Fig. S8. qRT-PCR of Ptch1-/+-driven medulloblastoma tumors treated in vivo with a Hh antagonist indicate that, unlike Ptch1 and Gli1, none of the hits are down-regulated by treatment with the Hh antagonist.
  • Fig. S9. qRT-PCR of Smo, Plk1, and Cdc2l1 knockdown in S12 cells in cell cycle experiments in Fig. 4F.
  • Fig. S10. Failure of Flag-tagged Cdc2, another Cdk-related kinase, to associate with Myc-tagged Sufu in coimmunoprecipitation experiments.
  • Fig. S11. Cdc2l1 activates the Hh pathway in a dose-dependent manner.
  • Table S1. Summary of primary hits from the Hh siRNA screen.
  • Table S2. Summary of nine validated hits from the Hh siRNA screen.
  • Table S3. List of qRT-PCR probe sets.
  • Table S4. List of PCR primers for DNA construct design.
  • Table S5. List of PCR primers for in situ hybridization probes.
