Urinary glycolipids of YC8 lymphoma bearing mice: effectors of glycosylation process.

: Glycolipids from YC8 lymphoma bearing mice urines have peen obtained by the method of Folch and fractionated on silicic column and on silica gel plates. One fraction, among the five obtained, may be used by sera galactosyltransferase as an acceptor for galactose, to form a new glycolipid compound. Furthermore this fraction has shown an inhibitory effect on phosphatase activity, in agreement with hypothesis which relates relates glycosyltransferase and phosphatase activities during tumorous process.
