Outline of Final Research Achievements

We examined the expression and function of G-protein coupled receptor (GPCR) for fat-soluble compounds in circulation and skeletal muscle system. We discovered the expression of some fat-soluble ligand receptors in heart and skeletal muscle. GPR30 is the GPCR for estrogen. Estrogen induced the phosphorylation of ERK signal cascade in primary-cultured cardiomyocyte and skeletal muscle cell line. Moreover, estrogen via GPR30 induced the proliferation and the highly-expression of several transcription factors of these cells. These results suggest that new function of G-protein coupled receptor (GPCR) for fat-soluble compounds improves for life style diseases and metabolic syndrome.
