(1) The data were grouped to determine differences between the experimental and the newly revised formats of the GRE-A measure, in addition to any differences among programs.
(2) However, a purified recombinant fragment of the GR which contained essentially only its DNA binding domain was unable to bind at the GME although it interacted strongly with a consensus GRE sequence.
(3) Although GRE images rapidly demonstrated flow in vascular intracranial lesions as high intensity, the vascular nature of these lesions was also clearly evident on SE images in most cases.
(4) We have used cloned rat glucocorticoid-receptor coding sequences to produce and characterize a novel class of receptor mutants that elicit GRE enhancer function in transfected cells even in the absence of hormone.
(5) The MR appearance of thrombosis of the portal vein and its branches using gradient echo (GRE) sequences is described.
(6) Assuming that function as a GRE reflects binding of glucocorticoid receptor, our activity data are consistent with the recognition of the GRE as two hexamer half-sites, each half-site recognized by a single subunit of a receptor dimer, probably in a cooperative fashion.
(7) The sequence recognition by the glucocorticoid receptor at the different defined glucocorticoid regulatory elements (GRE) is discussed and a consensus sequence formulated.
(8) We found that the promoter is extremely G + C rich (72% GC content) and contains a "TAATA" and a "CAT" box, eight "GGGCGG", three "CCGCCC" and two "CACCC" motifs and a motif similar to the glucocorticoid responsive element (GRE) which included two interchanged nucleotides "TCTTGT".
(9) Gel retardation analysis demonstrates that bacterially expressed c-Jun disrupts GR-GRE complexes.
(10) These results demonstrate the importance of GRE consensus sequences in glucocorticoid receptor interactions with DNA, and further identify a cause for high background binding observed when pBR322 DNA is used as a negative control in studies of glucocorticoid receptor-DNA interactions.
(11) Given the "time of flight" effect of GRE sequences, a scan plane perpendicular to the direction of flow was used to obtain maximal signal enhancement of flowing blood.
(12) All pRagCAT constructs in which the 5'-region contained at least one of the two GRE consensus sequences were stimulated by dexamethasone.
(13) Oversaturation (2.0 mumol Fe for SE sequences, greater than or equal to 1.0 mumol Fe for GRE sequences) led to image distortion and did not allow assessment of lymph node morphology.
(14) To accommodate the observed biphasic dose-response curve for highly specific glucocorticoids, and the shift-to-the-left for both classes of effector, we have proposed a model of a single "turn-on" nuclear acceptor site for glucocorticoid receptors (glucocorticoid regulatory element: GRE) and multiple, pre-emptive "turn-off" GREs, occupancy of any one of which will abrogate transcription; for progestins, we propose that all the GRE are alternate "turn-off" sites.
(15) A moderately repetitive DNA sequence, containing a TATA box, a GRE consensus, a Z-DNA forming sequence and two imperfect direct repeats at the extremities, is present a few nucleotides 5' of the human PAI-1 gene transcription start site, raising the possibility that this gene could have been activated by DNA insertion during evolution.
(16) In vitro transcription experiments using a Xenopus laevis cell-free extract have demonstrated that a DNA fragment containing a glucocorticoid response element (GRE) significantly enhances the expression of a methionine tRNA gene.
(17) R1881-activated transcription of a GRE-tk-CAT reporter gene construct was strongly diminished by both mutant receptors and was only partially restored using a 100-fold higher concentration of ligand compared with wild-type receptor.
(18) New cine GRE imaging techniques provide a noninvasive means for quantification of valvular as well as ventricular function.
(19) To investigate the detection of vascular extension of tumor with the GRE technique, findings in the preoperative GRE MR images of 26 patients with renal adenocarcinoma were compared with findings at surgery and pathologic examination.
(20) Our results demonstrate that in-plane GRE imaging and MR angiography can potentially be used as noninvasive methods for evaluating vascular patency in the presence of MR-compatible endovascular devices.

Example Sentences:
(1) To identify possible secretory determinants of impaired hyperadherence and stimulated migration of neonatal granulocytes (NGs), we performed correlative studies of: (a) specific granule content and exocytosis, (b) secretago-gue-mediated upregulation of f-met-leu-phe (fMLP) receptors, (c) the chemotactic induction of the adhesive glycoproteins Mac-1 alpha (complement receptor 3) and beta, and (d) morphometric assessments of specific (peroxidase negative) granule depletion following chemotactic stimulation.
(2) DMPP-elicited positive chronotropy was reduced by beta-receptor antagonists, hexamethonium, guanethidine (GuE), and tetrodotoxin.
(3) In preparations of the embryonic thorax in which the innervated heart was separated from brain and adrenal influences, DMPP elicited a GuE-sensitive cardioacceleration.
