A new member of the CAB gene family: structure, expression and chromosomal location of Cab -8, the tomato gene encoding the Type III chlorophyll a/b-binding polypeptide of photosystem I
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-03)
We have previously reported the isolation and characterization of tomato nuclear genes encoding two types of chlorophyll a/b-binding (CAB) polypeptides localized in photosystem (PS) I and two types of CAB polypeptides ...
Regulating leukotriene synthesis: The role of nuclear 5-lipoxygenase
(Wiley Subscription Services, Inc., A Wiley Company, 2005-12-15)
Leukotrienes are lipid messengers involved in autocrine and paracrine cellular signaling. They are synthesized from arachidonic acid by the 5-lipoxygenase pathway. Current models of this enzymatic pathway recognize that a ...
CXC chemokines mechanism of action in regulating tumor angiogenesis
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-03)
The CXC chemokines have recently been identified as a family of molecules which can regulate angiogenesis. Members of this family which contain the amino acid motif Glu–Leu–Arg in their amino terminus (ELR + ) act as ...
Modeling degranulation with liposomes: Effect of lipid composition on membrane fusion
(Springer-Verlag; Springer-Verlag New York Inc., 1994-08)
Degranulation involves the regulated fusion of granule membrane with plasma membrane. To study the role of lipid composition in degranulation, large unilamellar vesicles (LUVs) of increasing complexity in lipid compositions ...
The role of calcium in growth induced by indole-3-acetic acid and gravity in the leaf-sheath pulvinus of oat ( Avena sativa )
(Springer-Verlag; Springer-Verlag New York Inc., 1992-03)
Leaf-sheath pulvini of excised segments from oat ( Avena sativa L.) were induced to grow by treatment with 10 μM indole-3-acetic acid (IAA), gravistimulation, or both, and the effects of calcium, EGTA, and calcium channel ...
Pericellular proteolysis by leukocytes and tumor cells on substrates: focal activation and the role of urokinase-type plasminogen activator
(Springer-Verlag, 2004-04)
Previous studies have shown that the urokinase-type plasminogen activator receptor (uPAR) is localized to the adherence sites of leukocytes and tumor cells suggesting that pericellular proteolysis may accompany focal ...
Human neutrophils exhibit disparate chemotactic factor gene expression
(Elsevier, 1990-12-14)
The evolution of acute inflammation from initiation through resolution is associated with the changing character of the infiltrating leukocytes. Recruitment of these leukocytes is dependent upon the generation of chemotactic ...
Disparate regulation of interleukin 8 gene expression from blood monocytes, endothelial cells, and fibroblasts by interleukin 4
(Elsevier, 1990-09-14)
The role(s) of novel chemotactic cytokines as mediators in the pathogenesis of many acute and chronic disease states is becoming increasingly apparent. One of these cytokines, interleukin 8, is a product of both immune and ...
Absence of xanthine oxidase or xanthine dehydrogenase in the rabbit myocardium
(Elsevier, 1986-12-30)
We directly measured the activity of the enzymes xanthine oxidase and xanthine dehydrogenase in rabbit and rat hearts, using a sensitive radio-chemical assay. Neither xanthine oxidase activity nor xanthine dehydrogenase ...
Structural characterization of the catalytic domain of the human 5-lipoxygenase enzyme
(Springer-Verlag, 2002-04)
Leukotrienes are inflammatory mediators involved in several diseases. The enzyme 5-lipoxygenase initiates the synthesis of leukotrienes from arachidonic acid. Little structural information is available regarding 5-lipoxygenase. ...
