Effects of glucagon on adenosine 3',5'-monophosphate and guanosine 3',5'-monophosphate in human plasma and urine.
Glucagon, infused intravenously into fasting, well-hydrated, normal men in doses of 25-200 ng/kg per min, induced up to 30-fold increases in both plasma and urinary cyclic AMP. Cyclic GMP levels were unaffected by glucagon. Simultaneous cyclic AMP and inulin clearance studies demonstrated that the glucagon-induced increase in urinary cyclic AMP was entirely due to glomerular filtration of the e...
متن کاملThe presence of N-acetyllactosamine and lactose: beta (1-3)N-acetylglucosaminyltransferase activity in human urine.
Normal human urine was found to contain beta (1-3)N-acetylglucosaminyltransferase catalyzing the transfer of N-acetylglucosamine from UDP-GlcNAc to N-acetyllactosamine and lactose. Lacto-N-tetraose which carries the terminal Gal beta (1-3)GlcNAc structure was a poor acceptor. The product of the transferase reaction with N-acetyllactosamine as acceptor was identified by methylation analysis as G...
متن کاملRadioimmunoassay for adenosine 3', 5'-cyclic monophosphate and guanosine 3',5'-cyclic monophosphate in human blood, urine, and cerebrospinal fluid.
I describe a highly sensitive and very specific assay for cyclic AMP and cyclic GMP in body fluids. An adaptation of the method of Harper and Brooker [j. cyclic Nucleotide Res. 1,207 (1975)], its advantage lies in the fact that the simple acetylation of the samples--a procedure developed by these workers--greatly increases specificity and sensitivity beyond those of previous methods and permits...
متن کاملExpression of beta 1, beta 3, beta 4, and beta 5 integrins by human epidermal keratinocytes and non-differentiating keratinocytes
We have compared the adhesive properties and integrin expression profiles of cultured human epidermal keratinocytes and a strain of nondifferentiating keratinocytes (ndk). Both cell types adhered to fibronectin, laminin, and collagen types I and IV, but ndk adhered more rapidly and at lower coating concentrations of the proteins. Antibody blocking experiments showed that adhesion of both cell t...
متن کاملThe identification of the weak oestrogen equol [7-hydroxy-3-(4'-hydroxyphenyl)chroman] in human urine.
The identification (by gas chromatography-mass spectrometry and n.m.r.) for the first time of the weak oestrogen equol [7-hydroxy-3-(4'-hydroxyphenyl)chroman] in human urine is described. Preliminary results of its quantitative excretion in urine are reported and the potential significance of the occurrence of this compound is discussed.
