Rami A. Dalloul, Hyun S. Lillehoj, Masashi Okamura, Hang Xie, Wongi Min, Xicheng Ding, ...

Poultry coccidiosis is the major parasitic disease of poultry and, until now, no recombinant vaccine has been developed. Short oligodeoxynucleotides (ODNs) containing unmethylated CpG motifs (CpG...

Cooperative Interaction between Hepatocyte Nuclear Factor 4α and GATA Transcription Factors Regulates ATP-Binding Cassette Sterol Transporters ABCG5 and ABCG8▿

Sumi, Koichi, Tanaka, Toshiya, Uchida, Aoi, Magoori, Kenta, Urashima, Yasuyo, Ohashi, Riuko, ...

Cholesterol homeostasis is maintained by coordinate regulation of cholesterol synthesis and its conversion to bile acids in the liver. The excretion of cholesterol from liver and intestine is...

Hepatocyte Nuclear Factor 4α Contributes to Thyroid Hormone Homeostasis by Cooperatively Regulating the Type 1 Iodothyronine Deiodinase Gene with GATA4 and Krüppel-Like Transcription Factor 9▿ †

Ohguchi, Hiroto, Tanaka, Toshiya, Uchida, Aoi, Magoori, Kenta, Kudo, Hiromi, Kim, Insook, ...

Type 1 iodothyronine deiodinase (Dio1), a selenoenzyme catalyzing the bioactivation of thyroid hormone, is highly expressed in the liver. Dio1 mRNA and enzyme activity levels are markedly reduced in...

COUP-TFII acts downstream of Wnt/β-catenin signal to silence PPARγ gene expression and repress adipogenesis

Okamura, Masashi, Kudo, Hiromi, Wakabayashi, Ken-ichi, Tanaka, Toshiya, Nonaka, Aya, Uchida, Aoi, ...

Wnt signaling through β-catenin and TCF maintains preadipocytes in an un-differentiated proliferative state; however, the molecular pathway has not been completely defined. By integrating gene...
