Journal ArticleDOI
MCP-1 contributes to macrophage infiltration into adipose tissue, insulin resistance, and hepatic steatosis in obesity
Hajime Kanda,Sanshiro Tateya,Yoshikazu Tamori,Ko Kotani,Ko Kotani,Kenichi Hiasa,Riko Kitazawa,Sohei Kitazawa,Hitoshi Miyachi,Sakan Maeda,Kensuke Egashira,Masato Kasuga +11 more
TL;DR: It is suggested that an increase in MCP-1 expression in adipose tissue contributes to the macrophage infiltration into this tissue, insulin resistance, and hepatic steatosis associated with obesity in mice.
Journal ArticleDOI
FSP27 contributes to efficient energy storage in murine white adipocytes by promoting the formation of unilocular lipid droplets
Naonobu Nishino,Yoshikazu Tamori,Sanshiro Tateya,Takayuki Kawaguchi,Tetsuro Shibakusa,Wataru Mizunoya,Kazuo Inoue,Riko Kitazawa,Sohei Kitazawa,Yasushi Matsuki,Ryuji Hiramatsu,Satoru Masubuchi,Asako Omachi,Kazuhiro Kimura,Masayuki Saito,Taku Amo,Shigeo Ohta,Tomohiro Yamaguchi,Takashi Osumi,Jinglei Cheng,Toyoshi Fujimoto,Harumi Nakao,Kazuki Nakao,Atsu Aiba,Hitoshi Okamura,Tohru Fushiki,Masato Kasuga +26 more
TL;DR: The results suggest that FSP27 contributes to efficient energy storage in WAT by promoting the formation of unilocular lipid droplets, thereby restricting lipolysis and finding that the nature of lipid accumulation in Wat appears to be associated with maintenance of energy balance and insulin sensitivity.
Journal ArticleDOI
Interleukin-1 receptor antagonist and tumor necrosis factor binding protein decrease osteoclast formation and bone resorption in ovariectomized mice.
TL;DR: It is suggested that IL-6 is not essential for increasing bone resorption in the early postovariectomy period, and IL-1 and TNF play a direct role in mediating the effects of ovx on osteoclastogenesis and bone Resorption.
Journal ArticleDOI
Chemerin enhances insulin signaling and potentiates insulin-stimulated glucose uptake in 3T3-L1 adipocytes
Michiko Takahashi,Yutaka Takahashi,Kenichi Takahashi,Fyodor N. Zolotaryov,Kyoung Su Hong,Riko Kitazawa,Keiji Iida,Yasuhiko Okimura,Hidesuke Kaji,Sohei Kitazawa,Masato Kasuga,Kazuo Chihara +11 more
TL;DR: Chemerin potentiated insulin‐stimulated glucose uptake concomitant with enhanced insulin signaling in the 3T3‐L1 adipocytes and established that chemerin is a novel adipokine that regulates adipocyte function.
Journal ArticleDOI
Depressed expression of Klotho and FGF receptor 1 in hyperplastic parathyroid glands from uremic patients
Hirotaka Komaba,Shunsuke Goto,Hideki Fujii,Yasuhiro Hamada,Akira Kobayashi,Koji Shibuya,Yoshihiro Tominaga,Naoki Otsuki,Ken-ichi Nibu,Kimie Nakagawa,Naoko Tsugawa,Toshio Okano,Riko Kitazawa,Masafumi Fukagawa +13 more
TL;DR: The results suggest that the depressed expression of the Klotho-FGFR1 complex in hyperplastic glands underlies the pathogenesis of SHPT and its resistance to extremely high FGF23 levels in uremic patients.
