General description

A cell-permeable steroidal alkaloid and cholesterol mimic that displays both teratogenic and antitumor activities. It disrupts cholesterol bio-synthesis and specifically antagonizes shh (Sonic Hedgehog) signaling pathway through direct interaction with Smo (smoothened), a distant relative of G-protein-coupled receptors. A valuable tool for studying the involvement of shh signaling in the development of various tumors. Tomatidine (Cat. No. 614350) can be used as a negative control. Also available as a 10 mM solution in Ethanol (Cat. No. 239806).

Dopaminergic neurons develop in distinct neural domains by integrating local patterning and neurogenesis signals. While the proneural proteins Neurog1 and Olig2 have been previously linked to development of dopaminergic neurons, their dependence on local prepatterning and specific contributions to dopaminergic

Among molecules that bridge environment, cell metabolism, and cell signaling, hydrogen peroxide (H2O2) recently appeared as an emerging but central player. Its level depends on cell metabolism and environment and was recently shown to play key roles during embryogenesis, contrasting

It is well established that the formation of episodic memories requires multiple hippocampal mechanisms operating on different time scales. Early mechanisms of memory formation (synaptic consolidation) have been extensively characterized. However, delayed mechanisms, which maintain hippocampal activity as memories stabilize
