Isozyme patterns of 23 different enzymes were compared in normal, benign, and malignant breast tissues; in MCF-7 cells; and in organoids of normal human breast tissue. Benign lesions generally showed isozyme patterns similar to those of normal tissues. Lactate dehydrogenase isozyme 5 was significantly increased in malignant tumors; MCF-7 cells had only lactate dehydrogenase (L-lactate:NAD oxido...

Isozyme Profiles and Specific Organ Damage. CORNISH, HERBERT H., BARTH, MARY L., and DODSON, VERNON N. (1970). Toxicol. Appl. Pharmacol 16,41 l-423. Serum lactic dehydrogenase isozymes have been utilized as a means of detecting specific organ damage in rats. The serum LDH isozyme patterns seen in response to liver or kidney damage are markedly different, thus these patterns were utiiized to ide...

Calmodulin(CaM)-dependent cyclic nucleotide phosphodiesterase (PDE1) plays a critical role in the complex interactions between the cyclic nucleotide and Ca(2+) second messenger systems. Bovine brain contains two major PDE1 isozymes, designated according to tissue origin and subunit molecular mass as brain 60 kDa and 63 kDa PDE1 isozymes. Kinetic properties suggest that 63 kDa PDE1 isozyme is di...

A striking correlation between neural expression and high net negative charge in some teleost isozymes led to the interesting, yet untested, suggestion that negative charge represents an adaptation (via natural selection) to the neural environment. We examine the evolution of the triosephosphate isomerase (TPI) gene family in fishes for periods of positive selection. Teleost fish express two TP...

As part of a study of the regulation of aspartate aminotransferase isozymes (EC 2.6.1. l), we have investigated the characteristics of inhibition of the anionic and cationic isozymes by u-erythrose 4-phosphate and glycolaldehyde phosphate, the naturally occurring homologues of D-glyceraldehyde 3-phosphate. Erythrose-4-P has been found to be a time-dependent inhibitor of both the cationic and an...

In all eukaryotic cells that have been examined, specific membrane arrays are induced in response to increased levels of the ER membrane protein, HMG-CoA reductase. Analysis of these inducible membranes has the potential to reveal basic insights into general membrane assembly. Yeast express two HMG-CoA reductase isozymes, and each isozyme induces a morphologically distinct proliferation of the ...

Crude extracts of triple-cloned, purified cultures of 22 species of Mycoplasma and Acholeplasma were examined for expression of 21 isozyme systems routinely used to type mammalian cells. Nine previously described enzymes (purine nucleoside phosphorylase, adenylate kinase, dipeptidase, esterase, glyceraldehyde-3-phosphate dehydrogenase, glucose phosphate isomerase, glucose-6-phosphate dehydrogen...

The electrophoretic patterns of esterase (E-l), alcohol dehydrogenase (ADH), and glutamate oxaloacetate transaminase (GOT) isozymes were studied in two Spanish populations of the lily Scilla autumnalis with Bchromosome carrying individuals. The E-l isozyme activity appears only in those individuals with B-chromosomes. None of the bulbs free of B’s show it. Five bulbs, mosaic for B-content, were...
