The Forkhead Transcription Factor FoxC2 Inhibits White Adipocyte Differentiation

The Adipocyte-Expressed Forkhead Transcription Factor Foxc2 Regulates Metabolism Through Altered Mitochondrial Function

OBJECTIVE Previous findings demonstrate that enhanced expression of the forkhead transcription factor Foxc2 in adipose tissue leads to a lean and insulin-sensitive phenotype. These findings prompted us to further investigate the role of Foxc2 in the regulation of genes of fundamental importance for metabolism and mitochondrial function. RESEARCH DESIGN AND METHODS The effects of Foxc2 on expr...

Transcription factor PU.1 is expressed in white adipose and inhibits adipocyte differentiation.

PU.1 transcription factor is a critical regulator of hematopoiesis and leukemogenesis. Because PU.1 interacts with transcription factors GATA-2 and C/EBPalpha, and both are involved in the regulation of adipogenesis, we investigated whether PU.1 plays a role in the regulation of adipocyte differentiation. Our data indicate that PU.1 is expressed in white adipose tissue. PU.1 protein can also be...

Connective tissue growth factor inhibits adipocyte differentiation.

Adipocyte differentiation is a key process implicated in the pathogenesis of obesity and insulin resistance. Its regulation is triggered by a cascade of transcription factors, including the CCAAT/enhancer binding proteins (C/EBPs) and peroxisome proliferator-activated receptor-gamma (PPARgamma). Growth factors such as transforming growth factor-beta1 (TGF-beta1) are known to inhibit adipocyte d...

Genetic variation in the human winged helix/forkhead transcription factor gene FOXC2 in Pima Indians.

FOXC2 is a winged helix gene that has been shown to counteract obesity, hypertriglyceridemia, and diet-induced insulin resistance in rodents. Therefore, FOXC2 was analyzed as a candidate gene for susceptibility to type 2 diabetes in Pima Indians. Four variants were identified by sequencing the coding region, as well as 638 bp of the 5' region and 300 bp of the 3' region of the gene. Two single ...
