Publisher Summary This chapter discusses the nephrogenous cyclic AMP. The total amount of cyclic AMP (cAMP) excreted is the sum of that derived from two sources, that is, the filtered load of the nucleotide and nephrogenous cAMP. On an average, each component accounts for approximately 50% of the total quantity of cAMP excreted by normal individuals.

Microtubules, tubular structures of 240 A diameter, are widely distributed in plant and animal cells (for a review see (1)). These organelles are present in different sites of the cell; they make up the spindle fibres of the mitotic cells and they are prominent in the axons and dendrites of neurons.

On the Biological Role of Cyclic AMP
JAMA: The Journal of the American Medical Association, 1970Before discussing the role of cyclicadenylate, or adenosine 3′,5′-monophosphate (cyclic AMP) in biology, I would like to make a few brief remarks about another subject, the role of the basic scientist in medicine. I would like to hope that this and the subject that I have been asked to write about are not completely unrelated.

From Epinephrine to Cyclic AMP
Science, 1988Binding of catecholamines to the β-adrenergic receptor results in the activation of adenylate cyclase and the intracellular formation of adenosine 3′,5′-monophosphate (cAMP). In the past 20 years the events that lead from hormone binding at the cell surface receptor site to the synthesis of cAMP at the inner layer of the membrane have been

, 1976 Fibroblasts grown in monolayer on Petri dishes display various characteristics some of which help one to differentiate normal from malignant cells. For example, malignant fibroblasts, also called “transformed” cells, usually grow faster than their normal counterpart, they do not show density-dependent inhibition of growth, they move more rapidly ...

TRANSCRIPTIONAL REGULATION BY CYCLIC AMP
Annual Review of Biochemistry, 1997A number of hormones and growth factors have been shown to stimulate target cells via second messenger pathways that in turn regulate the phosphorylation of specific nuclear factors. The second messenger cyclic AMP, for example, regulates a striking number of physiologic processes, including intermediary metabolism, cellular proliferation, and ...

Adenosine 3′,5′-monophosphate (cyclic AMP) is a ubiquitous nucleotide, having a myriad of biological effects. Tissue specificity of cyclic AMP actions is provided by the hormone-sensitive adenylate cyclase, located on the inner side of the plasma membrane which converts ATP to cyclic AMP.

CYCLIC AMP AND INSULIN RELEASE
Acta Paediatrica, 1977Abstract. The role of cyclic adenosine‐3′,5′‐monophosphate (CAMP) for insulin secretion has been investigated. In isolated islets of Langerhans from the rat, glucose increases cAMP concomitant with insulin secretion. Stimulation of these two parameters is likewise reversible in parallel. The minimal and maximal concentrations of glucose eliciting CAMP

The variety of topics under consideration in this book attests to the importance of cAMP in immunology. Similarly, many of the functions ascribed to microtubules are important in a variety of immunologic situations. These functions all involve movement, either of constituents within cells or of cells themselves.
