Diets containing genetically modified (GM) potatoes expressing the lectin Galanthus nivalis agglutinin (GNA) had variable effects on different parts of the rat gastrointestinal tract. Some effects, such as the proliferation of the gastric mucosa, were mainly due to the expression of the GNA transgene. However, other parts of the construct or the genetic transformation (or both) could also have ...

Macrosialin (mouse CD68), a macrophage-specific member of the lysosomal-associated membrane protein family, displays N-linked glycosylation and a heavily sialylated, mucin-like domain. We show that phagocytosis of zymosan by inflammatory peritoneal macrophages potently alters glycan processing of macrosialin in vitro. The phagocytic glycoform is not induced by other forms of endocytosis and dep...

Treatment of a sodium dodecyl sulfate-polyacrylamide gel with periodic acid-Schiff (PAS) stain or blotting with Galanthus nivalis agglutinin revealed the presence of several glycosylated polypeptides in a partially purified detergent extract of the membrane fraction of Sulfolobus solfataricus. One of the glycoproteins comigrated with the membrane-associated protein-serine/threonine kinase from ...

BACKGROUND AND AIMS Seeds of the moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus, dispersed during spring or early summer, germinated poorly in laboratory tests. Seed development and maturation were studied to better understand the progression from developmental to germinable mode in order to improve seed collection and germination practices in these and similar...

In the present work combined glycan-, lectin-, and immunoblotting of isolated brain and kidney membranes shows that the alpha and beta subunits of Na,K-ATPase are the most abundant glycoproteins. Further, Datura stramonium and Galanthus nivalis agglutinins recognize the Na,K-ATPase subunits in a mutually exclusive manner in membranes from human, rabbit and rat brain or human, rabbit, rat, pig a...

Spring is a time of preparation, planting, and ftrst blooms. The ftrst bloom of our spring season is the Playford Ball, although like the snowdrops coming up at the same time, we often have to push through snow to fmd it. The ball will be held on Saturday, March 7, at Monument Hall in Concord. It turns out that the Weston Town Hall is being used, close to the date of the Ball, by a drama group ...
