Background and Purpose- Aortic arch atherosclerosis (AAA) is a possible source of embolism in patients with embolic stroke undetermined source. Previous studies reported high rates events AAA, especially those high-risk AAA. This exploratory analysis NAVIGATE ESUS (New Approach Rivaroxaban Inhibition Factor Xa Global Trial Versus ASA to Prevent Embolism Embolic Stroke Undetermined Source) focused on AAA assessed their characteristics, recurrence rates, response treatment. Methods- The...

Abstract Traumatic brain injury (TBI) is associated with disruption of cerebral blood flow leading to localized hypoxia. Thyroid hormone (TH) treatment, administered shortly after injury, has been shown promote neural protection in rodent TBI models. The mechanism TH protection, however, not established. We used mouse primary cortical neurons investigate the effectiveness and possible pathways T3-promoted cell survival exposure hypoxic injury. Cultured were exposed hypoxia (0.2% oxygen) for...

1α-hydroxymethyl-25-hydroxyvitamin D3 and 1β-hydroxymethyl-3α,25-hydroxyvitamin D3, two analogs with modifications restricted to the A ring, bind poorly vitamin D receptor (VDR). The effective doses required for 50% of maximal binding activity (ED50) are 7 x 10-7 M former 8 10-8 latter, ED50 their growth-inhibitory activities is greater than 10-6 M.

Twenty-epi analogs of 1α,25-dihydroxyvitamin D3 (1,25D3) are 100-1000 times more potent transcriptionally than the natural hormone. To determine whether this enhanced activity is mediated through modulation dimerization process or interaction with coactivators, we performed quantitative protein-protein assays in vitro translated vitamin D receptor (ivtVDR) and fusion proteins containing glutathione-S-transferase (GST) either ligand-binding domain retinoid X (RXRα), nuclear...

Thyroid hormone receptor β (THRB) is posttranslationally modified by small ubiquitin-like modifier (SUMO). We generated a mouse model with mutation that disrupted sumoylation at lysine 146 (K146Q) and resulted in desumoylated THRB as the predominant form tissues. The K146Q mutant mice had normal serum thyroxine (T4), markedly elevated thyrotropin-stimulating (TSH; 81-fold above control), enlargement of both pituitary thyroid gland. marked elevation TSH, despite T4, indicated blunted feedback...

Kallikrein-binding protein (KBP) is a component of the kallikrein-kinin system that mediates vasodilation and inhibits tumor growth by antagonizing vascular endothelial factor-mediated angiogenesis. We demonstrate KBP gene expression repressed T(3) modulated orphan nuclear receptor, chicken ovalbumin upstream promoter transcription factor 1 (COUP-TF1).
