Galectin-1, a member of the family of beta-galactoside binding proteins, has growth regulatory and immunomodulatory activities. We report here that galectin-1, expressed by stromal cells in human thymus and lymph nodes, is present at sites of cell death by apoptosis during normal T-cell development and maturation. Galectin-1 induced apoptosis of activated(More)
In order to obtain an estimate of the overall level of correlation between mRNA and protein abundances for a well-characterized pharmaceutically relevant biological system, we have analyzed human liver by quantitative two-dimensional electrophoresis (for protein abundances) and by Transcript Image methodology (for mRNA abundances). Incyte's LifeSeq database(More)
Postmortem analysis of brains of patients with Alzheimer's disease (AD) has led to diverse theories about the causes of the pathology, suggesting that this complex disease involves multiple physiological changes. In an effort to better understand the variety and integration of these changes, we generated a gene expression profile for AD brain. Comparing(More)
The ABC1 transporter was identified as the defect in Tangier disease by a combined strategy of gene expression microarray analysis, genetic mapping, and biochemical studies. Patients with Tangier disease have a defect in cellular cholesterol removal, which results in near zero plasma levels of HDL and in massive tissue deposition of cholesteryl esters.(More)
We have previously shown that human bactericidal/permeability-increasing protein (BPI) is able to inhibit serum-dependent lipopolysaccharide (LPS)-mediated activation of human monocytes and neutrophils in vitro, and to counteract the lethal effects of LPS challenge in vivo. Lipopolysaccharide-binding protein (LBP) is a serum protein which participates in(More)
Synovial fluid from arthritic patients contains multiple forms of phospholipase A2 (PLA2), as resolved by high performance liquid chromatography (Seilhamer, J.J., Plant, S., Pruzanski, W., Schilling, J., Stefanski, E., Vadas, P., and Johnson, L. K. (1989) J. Biochem. (Tokyo), submitted for publication). Here we describe the cloning of a human 4.5-kilobase(More)
The pattern of expression of an endogenous lectin, galectin-1, was examined in human lymphoid tissue. Galectin-1 was detected in the endothelial cells lining specialized vessels, termed high endothelial venules, in activated lymphoid tissue, but not in a resting lymph node. Cultured endothelial cells (human aortic and umbilical vein endothelial cells (HAECs(More)
Mammals are now known to contain at least two distinct classes of phospholipases A2, the progenitors of which can be seen in the venoms of snakes. Mammalian "Type I" PLA2, synthesized primarily by the pancreas, is also present in smaller amounts in other tissues including lung, spleen, and kidney. Recently, a mammalian "Type II" PLA2 has been sequenced, and(More)
The tissue inhibitors of metalloproteinases (TIMPs) comprise a family of proteins, of which two members have so far been described in humans. We have cloned and sequenced a third human TIMP (hTIMP-3) from phorbol ester-differentiated THP-1 cells stimulated with bacterial lipopolysaccharide. The open reading frame encodes a 211-amino-acid precursor including(More)
The Group IIA phospholipase gene (PLA2G2A) protein coding regions exhibit significant homology with recently described Group IIC (PLA2G2C) and Group V (PLA2GV) genes. All three genes are present in many mammalian species and are expressed in a tissue-specific pattern. Here, we demonstrate in human that they are tightly linked and map to chromosome(More)
