CXCR1 Regulates Pulmonary Anti-Pseudomonas Host Defense.
Pseudomonas aeruginosa is a key opportunistic pathogen causing disease in cystic fibrosis (CF) and other lung diseases such as chronic obstructive pulmonary disease (COPD). However, the pulmonary host defense mechanisms regulating anti-P. aeruginosa immunity remain incompletely understood. Here we demonstrate, by studying an airway P. aeruginosa infection model, in vivo bioluminescence imaging,...
متن کاملThermophysical properties and oxygen transport in (Thx,Pu1−x)O2
Using Molecular Dynamics, this paper investigates the thermophysical properties and oxygen transport of (Thx,Pu1-x)O2 (0 ≤ x ≤ 1) between 300-3500 K. In particular, the superionic transition is investigated and viewed via the thermal dependence of lattice parameter, linear thermal expansion coefficient, enthalpy and specific heat at constant pressure. Oxygen diffusivity and activation enthalpy ...
متن کاملPTEN regulates Mdm2 expression through the P1 promoter.
MDM2 is an oncoprotein that controls tumorigenesis through both p53-dependent and -independent mechanisms. Mdm2 mRNA level is transcriptionally regulated by p53 in response to stress such as DNA damage, and its protein level and subcellular localization are post-translationally modulated by the AKT serine/threonine kinase. Previous studies showed that PTEN, a dual specificity phosphatase that a...
متن کاملThe ELR+CXCL chemokines and their receptors CXCR1/CXCR2
The long-term efficacy of anti-angiogenesis drugs targeting vascular endothelial growth factor (VEGF) and VEGF receptors in the treatment of renal cell carcinoma (RCC) has been lacking. We have shown that the ELR+CXCL cytokines and their (C-X-C) chemokine receptors, namely CXCR1 and CXCR2, stimulate cancer cell proliferation, tumor inflammation, and angiogenesis. Hence, this essential molecular...
متن کاملTFII-I regulates Vbeta promoter activity through an initiator element.
In our effort to understand the transcriptional regulation of naturally occurring TATA-less but initiator (Inr)-containing genes, we have employed the murine T-cell receptor Vbeta 5.2 promoter as a model. Here we show by transient-transfection assays that the Inr binding transcription factor TFII-I is required for efficient expression of the Vbeta promoter in vivo. Mutations in the Inr element ...
