cyclopamine

a steroidal alkaloid in the plant Veratrum californicum responsible for the development of the cyclopian deformity caused by feeding the plant to pregnant ewes on the 14th day of pregnancy.

Cyclopamine and quercetin suppress the growth of leukemia and lymphoma cells.
However, several teratogens, including arsenic, cyclopamine, and thalidomide are currently used as anticancer drugs.
The metabolic reprogramming from mitochondrial respiration (Q-HSCs) to glycolysis (A-HSCs) is thought to require hedgehog (Hh) signaling, because cyclopamine, which blocks hedgehog signaling by binding to Smoothened (Smo), inhibited the accumulation of the PKM2-positive cells generated when liver repair is provoked by acute partial hepatectomy.
He wrote about the baby's rare defect called cyclopia which happens when the mother was exposed to cancer drug Cyclopamine during pregnancy.
Studies using HH inhibitors for therapy of BCCs have been published or are currently under way, for example, with the topical retinoid tazarotene, the plant alkaloid cyclopamine, and derivatives such as vismodegib (GDC-044), which target SMO.
2002) used cyclopamine, an inhibitor of Hedgehog (Hh) signaling, and showed the involvement of Hh signaling in fin-ray bone differentiation.
Importantly, the resistant cells that exhibited no decrease in the levels of Shh and Bcl-2, were sensitized to curcumin by the addition of the Shh antagonist, cyclopamine.
2002) investigated the effects of cyclopamine under the expression of signalling genes shh and noticed that there was a reduction followed by inhibition in fin regeneration, as well as the formation of little or no actinotrichia and a distal accumulation of pigment cells.
On the other hand, another Hedgehog pathway inhibitor called cyclopamine acts near the beginning of the signalling cascade.
Students make a hypothesis about the cause of the cyclopia based on other information provided about cyclopamine and Shh.
