OBJECTIVE Anti-Tr is among the better described autoantibodies in paraneoplastic cerebellar degeneration (PCD) combined with Hodgkin lymphoma (HL); however, the Tr antigen remains unidentified. METHODS We used immunoprecipitation of total rat brain extract followed by mass spectrometry to identify the antigen recognized by anti-Tr-positive sera. By Western blotting and cell-based assays, we t...
BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We inclu...
Estrogen receptor (ER) and thyroid hormone receptors (TRs) are ligand-dependent nuclear transcription factors that can bind to an identical half-site, AGGTCA, of their cognate hormone response elements. By in vitro transfection analysis in CV-1 cells, we show that estrogen induction of chloramphenicol acetyltransferase (CAT) activity in a construct containing a CAT reporter gene under the contr...
Objective: Via the use of an alternative promoter, a truncated c-KIT protein (tr-KIT) 30-50 kDa is generated, lacking extracellular and transmembrane domains. Moreover, over-expression tr-KIT, stronger activator than c-KIT, appears to be specific prostate cancer (PCa). Also, Imatinib, tyrosine kinase inhibitor, blocks activity full-length but has no effect on tr-KIT in PCa. Tr-KIT its own nucle...
Infection is associated with low serum thyroid hormones and thyrotropin levels. Here we demonstrate that infection also reduces thyroid hormone receptor (TR) expression. In gel shift experiments, retinoid X receptor (RXR)/TR DNA binding was reduced in mouse liver by 60 and 77%, respectively, 4 and 16 h after lipopolysaccharide (LPS) administration. Surprisingly, LPS did not decrease either TR-a...
Objective- To compare transabdominal (TA) and transrectal (TR) ultrasonography of the prostate gland. Design- Experimental study. Animals- 10 intact male dogs that required euthanasia for reasons other than prostatic disease. Procedures- Prostatic length (L), width (W) and height (H) were measured in T A (L1, W1 and H1) and TR (L2 and H2...
