We have shown previously that GH3 cells transfected with the rat GnRH receptor cDNA ( GGH3 - 1 ' cells ) support the expression of a cotransfected fusion gene composed of 797 base pairs of rat LHbeta gene 5 ' - flanking sequence and the first 5 base pairs of the 5 ' - untranslated region fused to a luciferase reporter ( - 797 / + 5LHbetaLUC ) and respond to a GnRH agonist with a 10 - fold stimulation of activity .
 rat GnRH receptor cDNA, rat LHbeta gene 5 ' - flanking sequence, luciferase reporter ( - 797 / + 5LHbetaLUC ), GnRH
