Primary erythermalgia is a rare autosomal dominant disease characterised by intermittent burning pain with redness and heat in the extremities. A previous study established the linkage of primary erythermalgia to a 7.94 cM interval on chromosome 2q, but the causative gene was not identified. We performed linkage analysis in a Chinese family with primary(More)
Degeneration of dopaminergicrgic neurons in the substantia nigra of the brain is a hallmark of Parkinson's disease and inflammation and oxidative stress are closely associated with the pathogenesis of degenerative neurological disorders. Treatment of rat mesencephalic mixed neuron-glia cultures with lipopolysaccharide (LPS)-activated microglia, resident(More)
Inflammation in the brain has been increasingly associated with the development of a number of neurological diseases. The hallmark of neuroinflammation is the activation of microglia, the resident brain immune cells. Injection of bacterial endotoxin lipopolysaccharide (LPS) into the hippocampus, cortex, or substantia nigra of adult rats produced(More)
To understand how the Wnt coreceptor LRP-5 is involved in transducing the canonical Wnt signals, we identified Axin as a protein that interacts with the intracellular domain of LRP-5. LRP-5, when expressed in fibroblast cells, showed no effect on the canonical Wnt signaling pathway by itself, but acted synergistically with Wnt. In contrast, LRP-5 mutants(More)
We recently reported that formation of allopolyploid wheat was accompanied by rapid nonrandom changes in low-copy noncoding DNA sequences. In this report we show that following allopolyploidization, changes also occurred in coding sequences. Genomic DNA of nine different newly synthesized amphiploids of different ploidy levels and their parental lines was(More)
We have reported previously that introgression by Zizania latifolia resulted in extensive DNA methylation changes in the recipient rice genome, as detected by a set of pre-selected DNA segments. In this study, using the methylation-sensitive amplified polymorphism (MSAP) method, we globally assessed the extent and pattern of cytosine methylation alterations(More)
BACKGROUND Turcot's syndrome is characterized clinically by the concurrence of a primary brain tumor and multiple colorectal adenomas. We attempted to define the syndrome at the molecular level. METHODS Fourteen families with Turcot's syndrome identified in two registries and the family originally described by Turcot and colleagues were studied. Germ-line(More)
A map of the barley genome consisting of 295 loci was constructed. These loci include 152 cDNA restriction fragment length polymorphism (RFLP), 114 genomic DNA RFLP, 14 random amplified polymorphic DNA (RAPD), five isozyme, two morphological, one disease resistance and seven specific amplicon polymorphism (SAP) markers. The RFLP-identified loci include 63(More)
Sphingomyelin hydrolysis and ceramide generation catalyzed by sphingomyelinases (SMase) are key components of the signaling pathways in cytokine- and stress-induced cellular responses. In this study, we report the partial purification and characterization of the membrane bound, neutral pH optimal, and magnesium-dependent SMase (N-SMase) from rat brain.(More)
Cultivated soybean ( Glycine max) is an economically important crop that is grown for its oil and protein products. A better knowledge of its genetic diversity will be valuable for the utilization, conservation, and management of germplasm collections. Using the database of the National Germplasm Evaluation Program of China (NGEPC), we studied the(More)
