basic FUNCTION	nuclear hormone receptor that regulates multiple physiological and pathophysiological processes (Niu 2009)
	inhibit erythroid maturation not only through a transcriptional mechanism, but also through a rapid membrane-associated pathway that interferes with EPO receptor signaling (Stellacci 2009)
	regulates target genes by associating with specific DNA binding sites, the sequences of which differ between genes (Meijsing 2009)
	coactivation of NR3C1 and NFKB alters signaling pathways that are regulated by each factor separately and provide insight into the networks underlying the NR3C1 and NFKB crosstalk
	endothelial NR3C1 is a critical regulator of NFKB1 activation and nitric oxide synthesis in sepsis
	in the brain, has been implicated, amongst others, in feedback regulation of the hypothalamic-pituitary-adrenal axis, with potential deficits during aging and in depression
	is required for fetal heart maturation
	ligand-dependent transcription factor of the nuclear receptor superfamily
	NR3C1 -dependent repression of elongation-controlled genes was abolished specifically in negative elongation factor-deficient macrophages
	both NR3C1 and FOXO1 are required for ANGPTL4 transcription activation, and FOXO1 negatively mediates the suppressive effect of insulin

	FOXA1 is a potent enhancer of NR3C1-induced transcription
	molecular interplay of NR3C1 and MEF2A in the control of genes important for neuronal plasticity
	GSK3B is important for NR3C1 transactivation activity and GSK3B inhibition suppresses NR3C1-stimulated gene expression
	FOXO3 is an immediate early glucocorticoid receptor (NR3C1) target, whose transcription is even further enhanced by conditions that mimic metabolic stress
	AGRP is a common orexigenic target gene of NR3C1 and BSX
	mutual antagonism between NR4A3 and NR3C1 to be a key rheostat for peripheral metabolic signals to centrally control energy balance
	NR3C1-induced expression of HNF4A may likely contribute to indirect SLC22A1 gene up-regulation by dexamethasone in primary human hepatocytes, but not in hepatocyte-derived tumor cell lines
	BUD23 is a novel regulator of chromatin structure affecting NR3C1 recruitment and function, contributing to loss of NR3C1 sensitivity in inflammation, with suppressed expression in pulmonary disease
	NR1D1 influences the stability and nuclear localization of NR3C1
	MDFIC is a binding partner for NR3C1, and NR3C1 directly represses the MDFIC gene, revealing a negative feedback loop by which glucocorticoids limit MDFIC activity
