Penn researchers find key to Sonic hedgehog control of brain development

The study identified a brain-specific enhancer that drives expression of the Shh gene in the hypothalamus, which regulates cell division of adult stem cells. A mutation in this enhancer sequence was found to cause a significant reduction in Shh activity, leading to holoprosencephaly.
