Abstract excerpt
Targeting of alpha-subunit gene expression within the pituitary is influenced by an upstream regulatory region that directs high level expression to thyrotropes and gonadotropes of transgenic mice. The same region also enhanced the activity of the proximal promoter in transfections of pituitary-derived alpha-TSH and alpha-T3 cells. We have localized the activating sequences to a 125-bp region that contains...
