| Research Abstract |
Estrogen plays a role for variety of physiological functions such as cell growth and cell differentiation through transcriptional regulation by nuclear estrogen receptors. However, intracellular pathways such as calcium influx and NO production in early responses occurred by estrogen stimulation have been unclear. To elucidate the early responses for the cells by estrogen, we have carried out high-throughput negative screening assay using RNAi library of GPCRs and kinases.
To determine accurately, we developed automation assay by JANUS, robot assay workstation using 96-well plates, and the cell response by estrogen stimulation was measured using mitochondria membrane potential assay in the RNAi-trasnfected cells. In several GPCR genes, mitochondria activities were significantly inhibited, suggesting the estrogen-dependent cell growth may be regulated by plasma membrane GPCRs. However, the results were further confirmed by the additional experiments.
