Slit is a secreted protein known to function through the Roundabout (Robo) receptor as a chemorepellent in axon guidance and neuronal migration, and as an inhibitor in leukocyte chemotaxis. Here we show Slit2 expression in a large number of solid tumors and Robo1 expression in vascular endothelial cells. Recombinant Slit2 protein attracted endothelial cells(More)
Glycogen synthase kinase-3 beta (GSK-3 beta) regulates cell metabolism, cell cycle, and cell fate through the phosphorylation of a diverse array of substrates. Herein, we provide evidence that supports a role for GSK-3 in mammalian meiosis and spermatogenesis. Immunostaining of testis sections showed that while GSK-3 alpha was ubiquitous in the seminiferous(More)
Conclusion Nasal obstruction can aggravate the psychological status of OSA patients, and nasal surgery should reduce this aggravation. Nasal surgery significantly improved sleep latency and ameliorated several polysomnographic characteristics. Background The aim of this study was to investigate the psychological status of patients with obstructive sleep(More)
The activity of the TGF-alpha-like ligand Spitz in Drosophila depends on Rhomboid, a seven-transmembrane spanning protein that resides in the Golgi and acts as a serine protease to cleave Spitz, thereby releasing the soluble ligand. Several rhomboids in Drosophila have been implicated in the processing of TGF-alpha-like ligands, and consequent EGF receptor(More)
VCP (also known as p97 or Cdc48p in yeast) is an AAA(+) ATPase regulating endoplasmic reticulum-associated degradation. After high-throughput screening, we developed compounds that inhibit VCP via different mechanisms, including covalent modification of an active site cysteine and a new allosteric mechanism. Using photoaffinity labeling, structural analysis(More)
The potential teratogenic effects and fetal toxicity of environmental estrogenic endocrine disruptors have become a great concern in recent years, and they have yet to be fully characterized. In the present study, the teratogenic effects of bisphenol A (BPA) and genistein (GEN) on rat embryos during their critical period of organogenesis were investigated(More)
Activation of Checkpoint kinase 1 (Chk1) following DNA damage mediates cell cycle arrest to prevent cells with damaged DNA from entering mitosis. Here we provide a high-resolution analysis of cells as they undergo S- and G₂-checkpoint bypass in response to Chk1 inhibition with the selective Chk1 inhibitor GNE-783. Within 4-8 h of Chk1 inhibition following(More)
A high density genetic linkage map for the complex allotetraploid crop species Brassica napus (oilseed rape) was constructed in a late-generation recombinant inbred line (RIL) population, using genome-wide single nucleotide polymorphism (SNP) markers assayed by the Brassica 60 K Infinium BeadChip Array. The linkage map contains 9164 SNP markers covering(More)
OPINION STATEMENT The heart has historically been considered to be a non-regenerative organ. Recent insights have suggested that cardiomyocytes have a small but measurable ability to regenerate. Moreover, recent work has also shown that manipulating the expression of specific genetic pathways can improve the ability of the heart to repair itself. These new(More)
The granulation of simultaneous partial nitrification and anaerobic ammonium oxidation (Anammox) was investigated in a single, oxygen-limited, sequencing batch reactor. In this research, the reactor was started anaerobically and fed using the synthetic medium described by Van de Graaf et al. to cultivate Anammox biomass after inoculation with methanogenic(More)
