Journal ArticleDOI
Stimulation of adipogenesis in fibroblasts by PPAR gamma 2, a lipid-activated transcription factor.
TL;DR: The results suggest that the physiologic role of PPAR gamma 2 is to regulate development of the adipose lineage in response to endogenous lipid activators and that this factor may serve to link the process of adipocyte differentiation to systemic lipid metabolism.
Journal ArticleDOI
A PGC1-α-dependent myokine that drives brown-fat-like development of white fat and thermogenesis
Pontus Boström,Jun Wu,Mark P. Jedrychowski,Anisha Korde,Li Ye,James C. Lo,Kyle A. Rasbach,Elisabeth A. Boström,Jang Hyun Choi,Jonathan Z. Long,Shingo Kajimura,Maria Cristina Zingaretti,Birgitte F. Vind,Hua Tu,Saverio Cinti,Kurt Højlund,Steven P. Gygi,Bruce M. Spiegelman +17 more
TL;DR: This article showed that PGC1α expression in muscle stimulates an increase in expression of FNDC5, a membrane protein that is cleaved and secreted as a newly identified hormone, irisin.
Journal ArticleDOI
Nutrient control of glucose homeostasis through a complex of PGC-1alpha and SIRT1.
Joseph T. Rodgers,Carlos Lerin,Wilhelm Haas,Steven P. Gygi,Bruce M. Spiegelman,Pere Puigserver +5 more
TL;DR: It is shown that the Sir2 homologue, SIRT1 controls the gluconeogenic/glycolytic pathways in liver in response to fasting signals through the transcriptional coactivator PGC-1α, and this findings have strong implications for the basic pathways of energy homeostasis, diabetes and lifespan.
Journal ArticleDOI
15-Deoxy-delta 12, 14-prostaglandin J2 is a ligand for the adipocyte determination factor PPAR gamma.
Barry M. Forman,Barry M. Forman,Peter Tontonoz,Jasmine Chen,Regina P. Brun,Bruce M. Spiegelman,Ronald M. Evans,Ronald M. Evans +7 more
TL;DR: A pivotal role is suggested for PPARγ and its endogenous ligand in adipocyte development and glucose homeostasis and as a target for intervention in metabolic disorders.
Journal ArticleDOI
Beige Adipocytes Are a Distinct Type of Thermogenic Fat Cell in Mouse and Human
Jun Wu,Pontus Boström,Lauren M. Sparks,Li Ye,Jang Hyun Choi,An Hoa Giang,Melin J. Khandekar,Kirsi A. Virtanen,Pirjo Nuutila,Gert Schaart,Kexin Huang,Hua Tu,Wouter D. van Marken Lichtenbelt,Joris Hoeks,Sven Enerbäck,Patrick Schrauwen,Bruce M. Spiegelman +16 more
TL;DR: Beige cells have a gene expression pattern distinct from either white or brown fat and are preferentially sensitive to the polypeptide hormone irisin, providing evidence that previously identified brown fat deposits in adult humans are composed of beige adipocytes.
