In this study, we examined whether tyrosine phosphorylation of the Toll-IL-1 resistance (TIR) domain of Toll-like receptor (TLR) 4 is required for signaling and blocked in endotoxin tolerance. Introduction of the P712H mutation, responsible for lipopolysaccharide (LPS) unresponsiveness of C3H/HeJ mice, into the TIR domain of constitutively active mouse(More)
To gain a better understanding of salt stress responses in plants, we used a proteomic approach to investigate changes in rice (Oryza sativa) root plasma-membrane-associated proteins following treatment with 150 mmol/L NaCl. With or without a 48 h salt treatment, plasma membrane fractions from root tip cells of a salt-sensitive rice cultivar, Wuyunjing 8,(More)
The cotton bollworm Helicoverpa armigera is the major insect pest targeted by cotton genetically engineered to produce the Bacillus thuringiensis toxin (transgenic Bt cotton) in the Old World. The evolution of this pest's resistance to B. thuringiensis toxins is the main threat to the long-term effectiveness of transgenic Bt cotton. A deletion mutation(More)
Sspg1d, one of endopolygalacturonases, is an important fungal effector secreted by the necrotrophic fungus Sclerotinia sclerotiorum during early infection. Using sspg1d as bait, a small C2 domain protein (designated as IPG-1) was identified by yeast two-hybrid screening of a canola cDNA library. Deletion analysis confirmed that the C-terminus of IPG-1 is(More)
Giant cell tumor (GCT) of bone is an aggressive skeletal tumor characterized by localized bone resorption. Matrix metalloproteinase-13 (MMP-13) is the principal proteinase expressed by the stromal cells of GCT (GCTSCs) and also considered to play a crucial role in formation of the osteolytic lesion in GCT. However, the exact mechanism of the regulation of(More)
Endotoxin tolerance reprograms cell responses to LPS by repressing expression of proinflammatory cytokines, while not inhibiting production of anti-inflammatory cytokines and antimicrobial effectors. Molecular mechanisms of induction and maintenance of endotoxin tolerance are incompletely understood, particularly with regard to the impact of endotoxin(More)
AIMS To investigate whether alterations of myocardial strain and high-sensitive cardiac troponin T (cTnT) could predict future cardiac dysfunction in patients after epirubicin exposure. METHODS Seventy-five patients with non-Hodgkin lymphoma treated with epirubicin were studied. Blood collection and echocardiography were performed at baseline, 1 day after(More)
Toll-like receptor 4 (TLR4) recognition of lipopolysaccharide triggers signalosome assembly among TLR4, sorting (e.g. MyD88 adapter-like (Mal)) and signaling (e.g. MyD88) adapters, initiating recruitment and activation of kinases, activation of transcription factors, and production of inflammatory mediators. In this study we examined whether tyrosine(More)
An exquisite interplay of developmental cues, transcription factors, and coregulatory and signaling proteins support formation of skeletal elements of the jaw during embryogenesis and dynamic remodeling of alveolar bone in postnatal life. These molecules promote initial condensation of the mesenchyme, commitment of the mesenchymal progenitor to osteogenic(More)
