| Research Abstract |
We established stable transformed GT-7 cell line tranfected with reporter plasmid which consists of GnRH or clock genes (Pes2/Bmal1) promoter and luciferase gene. Using this plasmid, we examined the effect of kisspepin to the transcription activity of GnRH gene or clock genes. Kisspeptin induced the transcription activity of GnRH, although it did not change that of clock genes. We also tried to establish the perfusion system for monitoring continuous luciferase activity as well as GnRH secretion. But it has not been completed.
