Hedgehog/Smoothened

SMOΔC captured on cholesterol beads in the presence of increasing concentrations of free vismodegib or 20(S)-OHC (h). Results from one of two independent pull-down experiments are shown.

Apoptosis evaluation of UACC62R, SK-MEL-28 R and R3 cells treated with Gant61 (10 μM) for 48 h by flow cytometry detection of Annexin V staining.

(A)[3H]thymidine incorporation assay of B16F10 melanoma cells treated with DMSO or cyclopamine after incubation with SA-CM from WT and Cav1KO dermal fibroblasts. Representative phase-contrast images of B16F10 cells treated with SA-CM from WT and Cav1KO fibroblasts with cyclopamine are shown on the right. Similar experiments (B) were done with A-375 cells incubated with SA-CM from hTBJ1-shCtrl and hTBJ1-shCAV1 cells.

RU-SKI 43 blocks Shh signaling. (a) RU-SKI 43 blocks Gli activation. NIH 3T3 cells were cotransfected with vectors encoding 8× Gli-binding site (GliBS)-Firefly luciferase (unless indicated otherwise), Renilla luciferase reporter (pRL-TK) and Shh. Confluent cells were treated with DMSO, 10 μM LDE225, 10 μM RU-SKI 43 or 10 μM C-2. The firefly luciferase (FL)/Renilla luciferase (RL) ratio in cell lysates was calculated and normalized to that measured in DMSO-treated samples; error bars represent mean ± s.d. (n = 2–3). 

(D) Percentage cell death of OCI-AML3 cells was measured using the CellTiter-Glo® viability assay following 24 hours treatment with either sequential treatment of 1 μM Vorinostat with low (0.1 μM) or high dose (2.5 μM) SANT-1, or single agents. Data represents a biological replicate of 3, with data presented relative to the DMSO control (0% cell death). (E) Protein expression of SHH was measured following 24 hours treated with the four treatment strategies in OCI-AML3 cells. Equal loading was confirmed with β-Actin

Cell viability assays performed on H1650 and H1975 cells with various concentrations of BMS-833923 (B).

a-d) LoVo cells were separately or simultaneously treated with 1 μM purmorphamine and 1 μM thiostrepton for the indicated time. a The Gli1, FoxM1, and CCNB1 protein expression levels were examined by immunoblotting after drug treatment for 48 h. b Cell viability was detected after 6 days using an MTT assay. c LoVo cells treated with indicated drugs were cultured for 2 weeks, and outgrowth colonies were stained with crystal violet. d The matched colony count of (c). Error bars represent the mean and S.D. of three independent experiments. **, p < 0.01.

Activating Shh signaling by SAG injection in naïve mice significantly increased BDNF expression, and pretreatment with cyclopamine effectively prevented the upregulation of BDNF induced by SAG (E). Tissues were collected at 2 hours after SAG injection. Six mice were included in each group.
