Cyclopamine is an inhibitor of hedgehog (Hh) signaling, likely via direct inhibition of Smoothened, the accessory protein to the putative Hh receptor Patched. Cyclopamine is a teratogen isolated from the corn lily that causes usually fatal birth defects. It can prevent the fetal brain from dividing into two lobes (holoprosencephaly) and cause the development of a single eye. Cyclopamine can also be used to induce differentiation of human embryonic stem cells (hESCs) into hormone-expressing endocrine cells. In the very first at any time human affected person with metastatic pancreatic most cancers who was administered intravenous cyclopamine on a compassionate, experimental basis in Germany, cyclopamine had to be discontinued because of emergence of neurologic toxicities and hematologic toxicities. That may possibly severely impede or even prevent scientific trials with this promising therapeutic technique.

Curator's Comment: MCF-7 cell proliferation was inhibited by cyclopamine in a dose- and time-dependent manner, and the optimal inhibiting concentration was ten µmol/L and the optimal action time at 48 hours. With the time prolongation of cyclopamine action, the cells in G0/G1 phase were significantly increased, but the cells in S phase were significantly decreased (compared with blank control group, allp < 0.05). With the time prolongation of cyclopamine action, apoptosis rate of MCF-7 cells was also significantly increased (compared with blank control group, allp < 0.05). The level of cyclin D1 of MCF-7 cells was decreased, but cyclin p21 was increased (compared with blank control group, all p < 0.05).
