TGR5 is a member of the G protein-coupled receptor family and is activated by bile acids (BAs). TGR5 is thought to be a promising drug target for metabolic diseases because the activation of TGR5 prevents obesity and hyperglycemia in mice fed a high-fat diet (HFD). In the present study, we identified a naturally occurring limonoid, nomilin, as an activator(More)
We examined to determine whether hepatic gene expression is affected in mice in which blood lipid levels remain unchanged fed soy protein isolate (SPI) for a short time. We also examined SPI-mediated effects in farnesoid X receptor (FXR)-deficient mice. Compared with casein, SPI affected the expression of various hepatic genes related to lipid metabolism in(More)
Here we show that the larger the amount of glutamine added to the medium, the more the expression of genes related to lipid homeostasis is promoted by the activation of sterol regulatory element binding proteins (SREBPs) at the transcriptional and post-translational levels in human hepatoma HepG2 cells. Glutamine increases the mRNA levels of several SREBP(More)
The differentiation of preadipocytes into adipocytes is controlled by several transcription factors, including peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα), which are known as master regulators of adipogenesis. BCL11B is a zinc finger-type transcription factor that regulates the development of the skin(More)

Hepatocyte nuclear factor 4α (HNF4α) is a nuclear receptor that regulates the expression of genes involved in the secretion of apolipoprotein B (apoB)-containing lipoproteins and in glucose metabolism. In the present study, we identified a naturally occurring flavonoid, luteolin, as a repressor of HNF4α by screening for effectors of the human microsomal(More)
BCL11B is a zinc finger-type transcription factor that regulates the development of the white adipose tissue (WAT), skin, central nervous system, and immune system. BCL11B is required for proper adipocyte differentiation, and BCL11B-/- embryos at E19.5 have very low amounts of the subcutaneous WAT. Here, we demonstrated that BCL11B+/- mice have lower body(More)
Soy protein β-conglycinin has serum lipid-lowering and anti-obesity effects. We showed that single ingestion of β-conglycinin after fasting alters gene expression in mouse liver. A sharp increase in fibroblast growth factor 21 (FGF21) gene expression, which is depressed by normal feeding, resulted in increased postprandial circulating FGF21 levels along(More)
Sterol regulatory element-binding proteins (SREBPs) are the key transcription factors that modulate lipid biosynthesis. SREBPs are synthesized as endoplasmic reticulum-bound precursors that require proteolytic activation in the Golgi apparatus. The stability and maturation of precursor SREBPs depend on their binding to SREBP cleavage-activating protein(More)
