Dr. Yamaguchi is engaged in the fields of bone and calcium endocrinology and cell calcium signaling since 1971, and these researches are developed in the aspect of biochemistry, molecular biology, endocrinology, metabolism, nutrition, pharmacology, and toxicology. Dr. Yamaguchi has an interesting for cell signaling mechanism, bone biology, nutritional factor and osteoporosis prevention, diabetic osteoporosis, and cancer bone metastasis and osteolysis. Moreover, Dr. Yamaguchi discovered two novel proteins and genes; cell signaling suppressor protein (named regucalcin; 1978) and transcriptional factor RGPR-p117 (regucalcin gene promoter region-related protein; 2001) in mammalian cells. Dr. Yamaguchi generated regucalcin transgenic rats, which were registered as international patents (USA, EU, Japan, and Korea), and this animal is found to induce osteoporosis and hyperlipidemia. The research of regucalcin is focused as a scientific topic. Dr. Yamaguchi published over 500 English articles to professional journals with peer-review.
