Lung Phosphodiesterase Isoenzymes
1993The distinct phosphodiesterase isoenzyme activities in guinea-pig lung were identified and characterised. We demonstrate that protein kinase A catalyses the activation of lung Type V cyclic GMP phosphodiesterase. This occurs via a marked change in the Vmax for cyclic GMP hydrolysis.

AbstractA polyacrylamide disc gel electrophoretic technique is described for studying isoenzymes or multiple molecular forms of lipoxidase in extracts of fresh green peas, pea seeds, wheat, fresh green beans and green bean seeds. After electrophoresis, gels containing starch were incubated with linoleic acid.

Despite decades of research effort, there is still poor understanding of the molecular mechanisms underlying carcinogenesis, that process by which normal tissue gives rise to cancer cells either spontaneously or by experimental induction. In such transformations there are changes in regulation of cell division, gross metabolism and histological ...

Klinische Wochenschrift, 1965
In Lebermetastasen von Primartumoren verschiedener Organe wurden nach chromatographischer Trennung an DEAE-Cellulose die Isoenzymverteilungsmuster der LDH, der GOT, der GPT und der Aldolase bestimmt. Es zeigte sich, das die prozentuale Verteilung der einzelnen Fraktionen zum Teil erheblich differiert.

Studies on enzyme systems in human and experimental melanomas have been the subject of numerous papers [4, 5, 7, 11, 14, 17, 18]. Most common are the communications on studies of enzyme systems related to the synthesis of melanin and its metabolism in normal melanocytes and in melanoma cells [1, 3, 6, 9, 10, 12, 13, 15, 20, 22, 23]. In contrast to this

Analytical methods for and the clinical significance of ATP:creatine-N-phosphotransferase (EC 2.7.3.2, CK) isoenzymes have been described. The main assay methods for the isoenzymes are electrophoresis, ion-exchange chromatography and immunoinhibition.

Creatine kinase (CK), a widely distributed enzyme in the body, has its highest activities in skeletal muscle and myocardium; when serum CK activities are abnormally increased, injury to these organs must be part of the differential diagnosis. The isoenzyme CK-MB is the most important biochemical test in the diagnosis of acute myocardial infarction.

Isoenzymes of tetrameric proteins
Biopolymers, 1972AbstractA theory is presented concerning the possible arrangements of protomers in tetrameric molecules. Isoenzymes may exist even in the case of homotetramers if the asymmetry of the identical protomers is detectable. The number of tetrahedral isoenzymes that can be isolated depends on the nature of the intersubunit bonds and on the level of the ...

Alkaline Phosphatase Isoenzymes
CRC Critical Reviews in Clinical Laboratory Sciences, 1979At the time of admission, 4 to 8% of all hospital admissions have a elevation of alkaline phosphatase. This high incidence of alkaline phosphatasemia has resulted in not only a need to identify the source of the elevated alkaline phosphatase; it has also led to a marked proliferation in laboratory procedures aimed at identifying the various isoenzymes ...

Isoenzymes and Myocardial Infarction
New England Journal of Medicine, 1960PLASMA and serum enzyme-activity alterations have proved useful as laboratory parameters in the diagnosis of myocardial disease.1 Among the enzymes employed to reflect myocardial necrosis are aldol...
