Abstract excerpt
Recently, several cis-regulatory elements that play roles in LHbeta gene expression, and their cognate DNA-binding transcription factors, have been identified. These factors include Sp1, steroidogenic factor-1 (SF-1), and early growth response protein 1 (Egr-1). Using the GH3 pituitary cell line (which lacks SF-1) as a model, we demonstrate that expression of SF-1 or Egr-1 increases rat LHbeta gene promoter...
