It has recently been discovered that G protein-coupled receptors (GPCR) 41 and 43 are characterized by having the short chain fatty acids acetate and propionate as their ligands. The objective of this study was to investigate the involvement of GPCR41, GPCR43, and their ligands in the process of adipogenesis. We measured the levels of GPCR41 and GPCR43 mRNA(More)
Until now, the various proteins highly expressed in adipose tissues have been identified and characterized by traditional gene cloning techniques. However, methods of computer analysis have been developed to compare the levels of expression among various tissues, and genes whose expression levels differ significantly between tissues have been found. Among(More)
To investigate the role of claudin-6 in adipogenesis, claudin-6 mRNA was examined in adipose tissues and adipocyte differentiation. Claudin-6 mRNA was found to be differentially expressed in four different adipose tissues, and up-regulated in each fat depot of mice fed a high-fat diet as compared to a normal-fat diet. Levels of claudin-6 transcripts were(More)
The amago salmon, Oncorhynchus masou ishikawae, is an endemic subspecies of O. masou in Japan. Populations in the River Miya, located at the entry of Ise Bay, central Japan, represent indigenous wild populations. They have been isolated in small tributaries as a result of environmental degradation in recent decades, with some populations also partially(More)
The factors that control fat deposition in adipose tissues are poorly understood. It is known that visceral adipose tissues display a range of biochemical properties that distinguish them from adipose tissues of subcutaneous origin. However, we have little information on gene expression, either in relation to fat deposition or on interspecies variation in(More)
We investigated the role of thrombin in the pathogenesis in atherosclerosis and restenosis. First we examined the effect of thrombin on cultured human vascular smooth muscle cells (VSMC). We showed that thrombin acts as a mitogen on VSMC through thrombin receptor. The expression of thrombin receptor was increased in the cell lines of VSMC established from(More)
Visceral adipocytes differ in various biochemical properties from adipocytes of subcutaneous origin. However, information on differences in gene expression between visceral and subcutaneous fat depots is limited. Expression of the genes for the nonmuscle and muscle isoforms of the actin-binding protein cofilin was examined in subcutaneous and visceral fat(More)
