Thyroid hormone receptor-associated proteins and general positive cofactors mediate thyroid hormone receptor function in the absence of the TATA box-binding protein-associated factors of TFIID

Coactivators previously implicated in ligand-dependent activation functions by thyroid hormone receptor (TR) include p300 and CREB-binding protein (CBP), the steroid receptor coactivator-1 (SRC-1)-related family of proteins, and the multicomponent TR-associated protein (TRAP) complex. Here we show that two positive cofactors (PC2 and PC4) derived from the upstream stimulatory activity (USA) cofactor fraction act synergistically to mediate thyroid hormone (T3)-dependent activation either by TR or by a TR-TRAP complex in an in vitro system reconstituted with purified factors and DNA templates. Significantly, the TRAP-mediated enhancement of activation by TR does not require the TATA box-binding protein-associated factors of TFIID. Furthermore, neither the pleiotropic coactivators CBP and p300 nor members of the SRC-1 family were detected in either the TR-TRAP complex or the other components of the in vitro assay system. These results show that activation by TR at the level of naked DNA templates is enhanced by cooperative functions of the TRAP coactivators and the general coactivators PC2 and PC4, and they further indicate a potential functional redundancy between TRAPs and TATA box-binding protein-associated factors in TFIID. In conjunction with earlier studies on other nuclear receptor-interacting cofactors, the present study also suggests a multistep pathway, involving distinct sets of cofactors, for activation of hormone responsive genes.

Improving urban park design: A comparative and analytical study addressing resources available and components necessary to improve the environmental and economic sustainability of urban parks

Urban parks have long been valued for the environmental, social, and economic benefits they provide. Increasingly, parks are also being recognized as features important for sustainable city design. This Capstone Project will identify, compare, analyze, and discuss means for designing sustainable urban parks. Recommendations for designing sustainable urban parks, based on project results, include: 1) ensure park features will support high levels of human activity; 2) use gravel to construct park trails; 3) purchase playground structures made of recycled materials; 4) plant a high number of perennials in flowerbeds and other vegetated areas; 5) plant climate-appropriate plants in vegetated areas; 6) ensure parks have high levels of plant diversity; and 7) develop future studies further exploring sustainable park design.

European Criminal Law and General Principles of Union Law. Research Papers in Law, 5/2005

From the Introduction. The European Court of Justice, partly followed in this by the European legislator, has regulated Community law and policy through a set of general principles of law. For the Community legal order in the first pillar, general legal principles have developed from functional policy areas such as the internal market, the customs union, the monetary union, the common agricultural policy, the European competition policy, etc., which are of great importance for the quality and legitimacy of Community law. The principles in question are not so much general legal principles of an institutional character, such as the priority of Community law, direct effect or Community loyalty, but rather principles of law which shape the fundamental rights and basic rights of the citizen. I refer to the principle of legality, of nulla poena, the inviolability of the home, the nemo tenetur principle, due process, the rights of the defence, etc. Many of these legal principles have been elevated to primary Community law status by the European Court of Justice, often as a result of preliminary questions. Nevertheless, a considerable number of them have also been elaborated in the context of contentious proceedings before the Court of Justice, such as in the framework of European competition law and European public servants law.

Decentralisation of EC Competition Law Enforcement and General Principles of Community Law. Research Papers in Law, 4/2004

From the Introduction. By virtue of Council Regulation No. 1/2003, as of 1st May 2004 the full application of EC competition law will be entrusted to national competition authorities (hereinafter NCAs) and national courts. The bold reform of EC competition law enforcement adheres to the system of executive federalism1 which characterises the EC legal system. The repartition of competences within the Community allocates implementation of Community law mainly at Member States level. Pursuant to Article 10 EC, they are responsible for the implementation of the measures which have been adopted at Community level for the achievement of the objectives specified in the EC Treaty. Consequently, the attainment of the Community objectives depends very much upon the cooperation of national authorities, which act in accordance with their own national procedural rules.2 The various national procedural rules present themselves as conduits through which Community law is implemented and enforced. While as a rule Community law is not designed to alter national procedural rules, the Community legal order cannot afford to leave national procedural rules untouched when they are liable to hamper the effective application of Community law....For reason of space, this contribution intends only to highlight some aspects of Regulation No. 1/2003 with regard to which general principles of Community law are able to condition national procedural rules.
