The cytoplasmic domains of integrins are essential for cell adhesion. We report identification of a novel protein, ICAP-1 (integrin cytoplasmic domain- associated protein-1), which binds to the 1 integrin cytoplasmic domain. The interaction between ICAP-1 and beta1 integrins is highly specific, as demonstrated by the lack of interaction between ICAP-1 and(More)
Living in an enriched environment (EC) during development enhances memory function in adulthood; living in an impoverished environment (IC) impairs memory function. Compounds previously demonstrated to improve memory among IC rats include CDP-choline and uridine monophosphate (UMP). Brain phosphatidylcholine (PC) synthesis utilizes both the uridine formed(More)
PURPOSE Overexpression of the epidermal growth factor receptor (EGFR) promotes unregulated growth, inhibits apoptosis, and likely contributes to clinical radiation resistance of non-small cell lung cancer (NSCLC). Molecular blockade of EGFR signaling is an attractive therapeutic strategy for enhancing the cytotoxic effects of radiotherapy that is currently(More)
Icap1 alpha is a 200-amino acid protein that binds to the COOH-terminal 13 amino acids ((786)AVTTVVNPKYEGK(798)) of the integrin beta(1) subunit. Alanine scanning mutagenesis of this region revealed that Val(787), Val(790), and (792)NPKY(795) are critical for Icap1 alpha binding. The NPXY motif is a known binding substrate for phosphotyrosine binding (PTB)(More)
PURPOSE 5,6-Dimethylxanthenone-4-acetic acid (DMXAA) (AS1404), a small-molecule vascular disrupting agent currently in clinical trial, increases vascular permeability and decreases blood flow in both murine and human tumours. DMXAA induces tumour necrosis factor (TNF) in mice and the effects on vascular permeability are hypothesised to result from both(More)
INTRODUCTION Known prediction models for breast cancer can potentially by improved by the addition of mammographic density and common genetic variants identified in genome-wide associations studies known to be associated with risk of the disease. We evaluated the benefit of including mammographic density and the cumulative effect of genetic variants in(More)
The biosyntheses of the [NiFe]-hydrogenase and urease enzymes in Helicobacter pylori require several accessory proteins for proper construction of the nickel-containing metallocenters. The hydrogenase accessory proteins HypA and HypB, a GTPase, have been implicated in the nickel delivery steps of both enzymes. In this study, the metal-binding properties of(More)
BACKGROUND More women of fertile age are long-term survivors of cancer. However, population-based data on birth rates of female cancer survivors are rare. METHODS A total of 42,691 women ≤ 45 years with a history of cancer were identified from the Swedish Multi-Generation Register and the Swedish Cancer Register, for whom relative birth rates were(More)
One in five cancers in women is diagnosed prior to and during a woman's fertile years. Our study evaluates mortality risks in offspring of mothers with history of cancer. From the Swedish Multi-generation Register and the Cancer Register, we identified all 174,893 children whose mother had been diagnosed with cancer between 1958 and 2001. We categorized(More)
The ability to selectively target disease-related tissues with molecules is critical to the design of effective therapeutic and diagnostic reagents. Recognizing the differences between the in vivo environment and in vitro conditions, we employed an in vivo selection strategy to identify RNA aptamers (targeting motifs) that could localize to tumor in situ.(More)
