Induction of the lutropin/choriogonadotropin receptor in rat ovary during luteinization.
Molecular analysis of the induction of the lutropin/choriogonadotropin receptor during the process of luteinization of the rat ovary was performed. The appearance of receptor binding activity and an immunological analysis of the receptor using Triton solubilized membrane proteins show little receptor present in luteal tissue through day 3 subsequent to hCG treatment, with some in day 4, and a marked increase by day 5. A similar pattern was found in the analysis of RNA hybridizing to several probes derived from the published cDNA sequence suggesting that receptor induction occurs primarily at the level of transcription.
