For the investigation of the minimal structural requirements for cytokine induction, Staphylococcus aureus lipoteichoic acid derivatives with two, three, four, and five glycerophosphate backbone moieties, carrying each a d-alanyl residue, were needed. Based on two different glycerophosphate building blocks and 6b-O-phosphitylated gentiobiosyl diacylglycerol the desired target molecules (compoun...

A previous report from this laboratory (van Golde, L.M.G., Schulman, H., and Kennedy, E.P. (1973) Proc. Natl. Acad. Sci. U.S.A. 70, 1368-1372) described the discovery in Escherichia coli of a novel class of oligosaccharides, containing glucose as the sole sugar, substituted with glycerophosphate units derived from membrane phospholipids, and with succinic acid in O-ester linkage. These membrane...

A histochemical study was made of a-glycerophosphate dehydrogenase in human tumors of @30cases. Enzymatic activity was generally confined to the cell plasma in neoplastic cells, and stromal reaction was usually low or absent. The stainability for a-glycerophosphate dehydrogenase was constant in normal tissue, whereas that of neo plastic cells was variable. Squamous-cell carcinomas showed varyin...

In 1938-9 at the British Postgraduate Medical School, King & Aloisi isolated from dried pancreas a glycerophosphoric ester of choline which was found to be readily hydrolyzable. Evidence was also obtained for the existence of a dicholine ester. This work was published only in 1945 owing to war difficulties. In the same year Schmidt, Hershman & Thanmhauser (1945) reported the isolation of aglyce...

Jackson, Robert W. (Purdue University, Lafayette, Ind.), and Merwin Moskowitz. Nature of a red cell sensitizing substance from streptococci. J. Bacteriol. 91:2205-2209. 1966.-A method for purifying a streptococcal antigen which sensitizes red cells to agglutination by antiserum is described. The antigen, when purified by this method, is almost exclusively composed of glycerophosphate and d-alan...

BACKGROUND: this study was designed to characterize some of the biochemical and molecular genetic changes during reversion of human fat cells. METHODS: mature adipocytes were isolated from greater omental fat tissue of eight lean and 14 massively obese persons by established methodology. RESULTS: at day 7 of adherence to Leighton tubes, there was appreciable depletion of triacylglycerol, as wel...

Bone marrow cells, lymphocytes, lymph nodes, solid lymphoid tumors, spleen and ascites cells from mice implanted with leukemia have markedly decreased o-glycerophosphate and increased lactic dehydrogenase activities. A striking parallel between the ratio of these dehydrogenases and the progression of the leukemia was found. These data, in conjunction with related findings, suggest that the a-gl...

Soluble-protein and eight enzyme profiles obtained by polyacrylamide-gel electrophoresis were compared between Meloidogyne incognita and M. arenaria. Esterase, malate dehydrogenase, and alpha-glycerophosphate dehydrogenase patterns were distinctly characteristic for each species. Peroxidase and alpha-glycerophosphate dehydrogenase isoenzyme patterns varied when nematodes were propagated on diff...

1. A method is described for extraction and partial purification of mitochondrial l-3-glycerophosphate dehydrogenase from pig brain. 2. By the criteria that have so far been applied, the extraction and purification procedures do not modify the activity of the enzyme towards artificial electron acceptors. 3. The amounts of acid-liberatable flavine and iron in the preparation were measured. 4. A ...
