Tumor growth depends on nutrients and oxygen supplied by the vasculature through angiogenesis. Here, we show that the chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII), a member of the nuclear receptor family, is a major angiogenesis regulator within the tumor microenvironment. Conditional ablation of COUP-TFII in adults severely compromised neoangiogenesis and suppressed ...

OBJECTIVE Septal defects and coronary vessel anomalies are common congenital heart defects, yet their ontogeny and the underlying genetic mechanisms are not well understood. Here, we investigated the role of chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII, NR2F2) in cardiac organogenesis. METHODS AND RESULTS We analyzed embryos deficient in COUP-TFII and observed a spec...

Proposition 1: As I argued in the paper, there is no equilibrium in which the dictator uses a pure strategy and the ruling coalition conditions its decision to stage a coup on the observed signal. In any equilibrium in mixed strategies, (i) the ruling coalition stages a coup with probability βθ such that, given the correlation between his actions and the signal θ, the dictator is indifferent be...

The chicken ovalbumin upstream promoter transcription factor (COUP-TF) is a member of the steroid/thyroid hormone receptor superfamily about which little is known of its functional role in the cell. However, it is able to repress hormonal induction of target genes by vitamin D3 receptor (VDR), thyroid hormone receptor (TR), and retinoic acid receptor (RAR). We have shown previously that COUP-TF...

BACKGROUND The nuclear receptor chicken ovalbumin upstream promoter transcription factor II (COUP-TFII) is an important coordinator of glucose homeostasis. We report, for the first time, a unique differential regulation of its expression by the nutritional status in the mouse hypothalamus compared to peripheral tissues. METHODOLOGY/PRINCIPAL FINDINGS Using hyperinsulinemic-euglycemic clamps a...

During corticogenesis, late-born callosal projection neurons (CPNs) acquire their laminar position through glia-guided radial migration and then undergo final differentiation. However, the mechanisms controlling radial migration and final morphology of CPNs are poorly defined. Here, we show that in COUP-TFI mutant mice CPNs are correctly specified, but are delayed in reaching the cortical plate...

COUP-TF, an orphan member of the nuclear receptor superfamily, has been proposed to play a key role in regulating organogenesis, neurogenesis, and cellular differentiation during embryonic development. Since heterodimierization is a common theme within the nuclear receptor superfamily and has been demonstrated to modulate transcriptional properties of heterodimeric partners via allosteric inter...

COUP-TFII, an orphan member of the steroid receptor superfamily, has been implicated in mesenchymal-epithelial interaction during organogenesis. The generation of a lacZ knock-in allele in the COUP-TFII locus in mice allows us to use X-gal staining to follow the expression of COUP-TFII in the developing stomach. We found COUP-TFII is expressed in the mesenchyme and the epithelium of the develop...

The transcription factor COUP-TFI (NR2F1), an orphan member of the nuclear receptor superfamily, is an important regulator of neurogenesis, cellular differentiation and cell migration. In the forebrain, COUP-TFI controls the connectivity between thalamus and cortex and neuronal tangential migration in the basal telencephalon. Here, we show that COUP-TFI is required for proper axonal growth and ...
