Treatment with small molecule Hh inhibitors such as HhAntag and the natural product Cyclopamine, both binding to Smo, induces tumor remission in a genetic mouse model of medulloblastoma[1]. Cyclopamine is a Hedgehog (Hh) pathway antagonist. Cyclopamine suppresses cell growth. Cyclopamine (3 μM) suppression of Hh pathway activity and growth in digestive tract tumour cell lines correlates with expression of PTCHmRNA[2]. Cyclopamine is a steroidal alkaloid that inhibits Hh signalling through direct interaction with Smo[3].

Solvent & Solubility
DMSO : 5 mg/mL (12.15 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : 5 mg/mL (12.15 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.5 mg/mL (1.21 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.5 mg/mL (1.21 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL. * In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light)
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Cells are cultured in triplicate in 96-well plates in assay media to which 5E1 monoclonal antibody, ShhNp and/or Cyclopamine (3 μM) are added at 0 h at concentrations indicated in the main text. Viable cell mass is determined by optical density measurements at 490 nm (OD490) at 2 and 4 days using the CellTiter96 colorimetric assay. Relative growth is calculated as OD (day 4)-OD (day 2)/OD (day 2)[2].

Mice[3]
A total of 0.1 mL Hanks’ balanced salt solution and matrigel (1:1) containing 2×106 cells is injected subcutaneously into CD-1 nude mice. Tumors are grown for 4 days to a minimum volume of 125 mm3; treatment is initiated simultaneously for all subjects. Mice are injected subcutaneously with vector alone (triolein:ethanol 4:1 v/v) or a Cyclopamine suspension (1.2 mg per mouse in triolein:ethanol 4:1 v/v) daily for 7 days. At the end of the treatment period, tumours are excised from mice, weighed and then fixed for 3 h at 4°C with 4% paraformaldehyde, embedded in paraffin wax and sectioned (6 µm). Apoptotic cells are identified by TUNEL using recombinant Tdt. Sections are then counterstained with eosin. Eight ×20-magnified fields from regions corresponding to the exterior, middle and interior of two control and two cyclopamine-treated tumours are chosen at random. We counted the number of TUNEL-positive nuclei manually. Haematoxylin/eosin staining is done.
