T he absence of a biomarker to predict the aggressiveness of prostate cancer patients is the major obstacle in deciding which prostate cancer patient should be treated. In this report, we show that COUP transcription factor II (COUP-TFII), a member of the nuclear receptor superfamily, antagonizes the transforming growth factor (TGF)-b-induced growth barrier to facilitate tumor metastasis and pr...

In rodents, cortical interneurons originate from the medial ganglionic eminence (MGE) and caudal ganglionic eminence (CGE) according to precise temporal schedules. The mechanisms controlling the specification of CGE-derived interneurons and their role in cortical circuitry are still unknown. Here, we show that COUP-TFI expression becomes restricted to the dorsal MGE and CGE at embryonic day 13....

Linear scleroderma is a form of localized scleroderma that primarily affects the pediatric population. When it occurs on the scalp or forehead, it is termed "en coup de sabre". In the en coup de sabre subtype, many extracutaneous associations, mostly neurological, have been described. A patient with linear scleroderma en coup de sabre was noted to have ipsilateral brain cavernomas by magnetic r...

Embryonic nuclear proteins from the sea urchin Strongylocentrotus purpuratus bind in vitro to a cis-acting element that lies upstream of the actin gene CyIIIb and consists of two direct repeats homologous to steroid hormone response elements. This sea urchin element is specifically recognized by transcription factor COUP-TF from HeLa cell nuclear extracts as well. A sea urchin gene homologous t...

BACKGROUND Chicken ovalbumin upstream promoter transcription factor II (COUP-TFII) belongs to the steroid/thyroid hormone receptor superfamily and may contribute to the pathogenesis of obesity. It has not conclusively been established, however, whether its role is pro- or anti-adipogenic. METHODS AND RESULTS Gene silencing of Coup-tfII in 3T3-F442A preadipocytes resulted in enhanced different...

Human immunodeficiency virus type 1 (HIV-1) gene transcription is characterized by two temporally distinct phases. While the initial phase relies solely on cellular transcription factors, the subsequent phase is activated by the viral Tat transactivator. We have previously reported that the subsequent phase of viral gene transcription can be repressed by the chicken ovalbumin upstream promoter ...

Congenital diaphragmatic hernia (CDH), a life-threatening anomaly, is a major cause of pediatric mortality. Although the disease was described >350 years ago, the etiology of CDH is poorly understood. Here, we show that tissue-specific null mutants of COUP-TFII exhibit Bochdalek-type CDH, the most common form of CDH. COUP-TFII, a member of orphan nuclear receptors, is expressed in regions criti...

Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) has been implicated in the control of blood glucose by its potent effect on expression and signaling of various nuclear receptors. To understand the role of COUP-TFII in glucose homeostasis, conditional COUP-TFII-deficient mice were generated and crossed with mice expressing Cre under the control of rat insulin II gene prom...

Progesterone and estrogen are critical regulators of uterine receptivity. To facilitate uterine remodeling for embryo attachment, estrogen activity in the uterine epithelia is attenuated by progesterone; however, the molecular mechanism by which this occurs is poorly defined. COUP-TFII (chicken ovalbumin upstream promoter transcription factor II; also known as NR2F2), a member of the nuclear re...
