Recently we identified a novel human (h) multiprotein complex, called TATA-binding protein (TBP)-free TAFII-containing complex (TFTC), which is able to nucleate RNA polymerase II transcription and can mediate transcriptional activation. Here we demonstrate that TFTC, similar to other TBP-free TAFII complexes (yeast SAGA, hSTAGA, and hPCAF) contains the(More)
C-proteins have been isolated from rabbit red skeletal muscle (soleus and semitendinosus) and cardiac muscle and their structure and properties compared with those of white muscle C-protein. The Mr of white, red, and cardiac C-proteins are 135,000, 145,000, and 150,000, respectively, and their s20,w values are 4.3, 3.8, and 4.8 S, indicating that red(More)
Treatment of refractory Takayasu arteritis (TA) remains an unresolved clinical issue. Patients usually respond to glucocorticoid (GC) therapy, but often relapse on tapering of the GC dose. The aim of the present study was to assess the safety and efficacy of the interleukin-6 (IL-6) receptor antibody tocilizumab (TCZ) in patients with TA refractory to(More)
The origin and developmental mechanisms underlying coronary vessels are not fully elucidated. Here we show that myocardium-derived angiopoietin-1 (Ang1) is essential for coronary vein formation in the developing heart. Cardiomyocyte-specific Ang1 deletion results in defective formation of the subepicardial coronary veins, but had no significant effect on(More)
A DNA fragment of about 3.4 kilobase pairs that expressed the HgaI modification activity was cloned from the chromosomal DNA of Haemophilus gallinarum, and its nucleotide sequence was determined. Two open reading frames (ORF) which could code for structurally similar proteins were identified in the upstream and middle regions and a truncated ORF in the(More)
Bisphosphonates have been used for the treatment of hypercalcemia associated with malignancies and osteoporosis. It was previously reported that the mevalonate pathway is involved in nitrogen-containing bisphosphonate-induced apoptosis in osteoclasts and myeloma cells. The aim of this study was to determine the effects of two bisphosphonates, incadronate,(More)
Dialysis-related amyloidosis frequently develops in patients undergoing long-term hemodialysis, in which the major component of fibrils is beta(2)-microglobulin (beta2-m). To prevent the disease, it is important to stop the formation of fibrils. beta2-m has one disulfide bond, which stabilizes the native structure, and amyloid fibrils. Here, the effects of(More)
Amyloid fibril deposition is associated with over 20 degenerative diseases, including Alzheimer's, Parkinson's, and prion diseases. Although research over the last few years has revealed the morphology and structural features of the amyloid form, knowledge about the thermodynamics of amyloid formation is limited. Here, we report for the first time a direct(More)
Beta2-microglobulin (beta2-m), a protein responsible for dialysis-related amyloidosis, adopts an immunoglobulin domain fold in its native state. Although beta2-m has Trp residues at positions 60 and 95, both are located near the surface of the domain. Hence, beta2-m does not have a conserved Trp common to other immunoglobulin domains, which is buried in(More)
Morphological and biochemical phenotypes of cardiomyocyte hypertrophy are determined by neurohumoral factors. Stimulation of G protein-coupled receptor (GPCR) results in uniform cell enlargement in all directions with an increase in skeletal alpha-actin (alpha-SKA) gene expression, while stimulation of gp130 receptor by interleukin-6 (IL-6)-related(More)
