Research Interest: Polyhydroxyalkanoates (PHAs), bioprocess engineering, biopolymer fermentation, biogas, environmental biotechnology, and environmental microbiology

Research Interest: 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, diabetes and diabetic osteoporosis, cancer biology, and cancer bone metastasis. 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 was found to induce osteoporosis and hyperlipidemia. Moreover, Dr. Yamaguchi proposed the potential role of regucalcin as a key suppressor protein in carcinogenesis.  Currently, the research of regucalcin is focused as a scientific topic
