Abstract
Cyclic ADP-ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate (NAADP), two intracellular Ca2+ mobilizing second messengers, have been recognized as a fundamental signaling mechanism regulating a variety of cell or organ functions in different biological systems. Here we reviewed the literature regarding these ADP-ribosylcyclase products in vascular cells with a major focus on their production, physiological roles, and related underlying mechanisms mediating their actions. In particular, several hot topics in this area of research are comprehensively discussed, which may help understand some of the controversial evidence provided by different studies. For example, some new models are emerging for the agonist receptor coupling of CD38 or ADP-ribosylcyclase and for the formation of an acidic microenvironment to facilitate the production of NAADP in vascular cells. We also summarized the evidence regarding the NAADP-mediated two-phase Ca2+ release with a slow Ca2+-induced Ca2+ release (CICR) and corresponding physiological relevance. The possibility of a permanent structural space between lysosomes and sarcoplasmic reticulum (SR), as well as the critical role of lysosome trafficking in phase 2 Ca2+ release in response to some agonists are also explored. With respect to the molecular targets of NAADP within cells, several possible candidates including SR ryanodine receptors (RyRs), lysosomal transient receptor potential-mucolipin 1 (TRP-ML1) and two pore channels (TPCs) are presented with supporting and opposing evidence. Finally, the possible role of NAADP-mediated regulation of lysosome function in autophagy and atherogenesis is discussed, which may indicate a new direction for further studies on the pathological roles of cADPR and NAADP in the vascular system.

Abstract
Cyclic ADP-ribose (cADPR) is a novel Ca(2+) mobilizing second messenger, which is capable of inducing Ca(2+) release from the sarcoplasmic reticulum (SR) via activation of ryanodine receptors (RyR) in vascular cells. This signaling nucleotide has also been reported to participate in generation or modulation of intracellular Ca(2+) sparks, Ca(2+) waves or oscillations, Ca(2+)- induced Ca(2+) release (CICR) and spontaneous transient outward currents (STOCs) in vascular smooth muscle cells (VSMCs). With respect to the role of cADPR-mediated signaling in mediation of vascular responses to different stimuli, there is accumulating evidence showing that cADPR is importantly involved in the Ca(2+) response of vascular endothelial cells (ECs) and VSMCs to various chemical factors such as vasoactive agonists acetylcholine, oxotremorine, endothelin, and physical stimuli such as stretch, electrical depolarization and sheer stress. This cADPR-RyR-mediated Ca(2+) signaling is now recognized as a fundamental mechanism regulating vascular function. Here we reviewed the literature regarding this cADPR signaling pathway in vascular cells with a major focus on the production of cADPR and its physiological roles in the control of vascular tone and vasomotor response. We also summarized some publish results that unveil the underlying mechanisms mediating the actions of cADPR in vascular cells. Given the importance of Ca(2+) in the regulation of vascular function, the results summarized in this brief review will provide new insights into vascular physiology and circulatory regulation.

Abstract
The present study tested the hypothesis that cyclic ADP ribose (cADPR) serves as a novel second messenger to mediate intracellular Ca2+ mobilization in coronary arterial endothelial cells (CAECs) and thereby contributes to endothelium-dependent vasodilation. In isolated and perfused small bovine coronary arteries, bradykinin (BK)-induced concentration-dependent vasodilation was significantly attenuated by 8-bromo-cADPR (a cell-permeable cADPR antagonist), ryanodine (an antagonist of ryanodine receptors), or nicotinamide (an ADP-ribosyl cyclase inhibitor). By in situ simultaneously fluorescent monitoring, Ca2+ transient and nitric oxide (NO) levels in the intact coronary arterial endothelium preparation, 8-bromo-cADPR (30 microM), ryanodine (50 microM), and nicotinamide (6 mM) substantially attenuated BK (1 microM)-induced increase in intracellular [Ca2+] by 78%, 80%, and 74%, respectively, whereas these compounds significantly blocked BK-induced NO increase by about 80%, and inositol 1,4,5-trisphosphate receptor blockade with 2-aminethoxydiphenyl borate (50 microM) only blunted BK-induced Ca2+-NO signaling by about 30%. With the use of cADPR-cycling assay, it was found that inhibition of ADP-ribosyl cyclase by nicotinamide substantially blocked BK-induced intracellular cADPR production. Furthermore, HPLC analysis showed that the conversion rate of beta-nicotinamide guanine dinucleotide into cyclic GDP ribose dramatically increased by stimulation with BK, which was blockable by nicotinamide. However, U-73122, a phospholipase C inhibitor, had no effect on this BK-induced increase in ADP-ribosyl cyclase activity for cADPR production. In conclusion, these results suggest that cADPR importantly contributes to BK- and A-23187-induced NO production and vasodilator response in coronary arteries through its Ca2+ signaling mechanism in CAECs.

Abstract
In pemphigus vulgaris, treatment with systemic glucocorticosteroids is life saving; it may, however, cause severe side effects, including death. A patient with pemphigus vulgaris and myasthenia gravis was treated for approximately five years with the cholinomimetic Mestinon (pyridostigmine bromide), Imuran (azathioprine), and a topical corticosteroid gel before the need to introduce systemic glucocorticosteroids. Because activation of keratinocyte acetylcholine receptors also has been shown to abolish pemphigus IgG-induced acantholysis in cultured keratinocyte monolayers, a clinical trial of Mestinon was initiated in patients with active pemphigus vulgaris, pemphigus foliaceus, and paraneoplastic autoimmune multiorgan syndrome (also known as paraneoplastic pemphigus). First results indicate that nonsteroidal treatment of pemphigus is possible. Mestinon may be used to slow down progression of the disease and to treat mild cases with chronic lesions on limited areas. Stimulation of the keratinocyte- acetylcholine axis may lead to a therapeutic effect through any of the following mechanisms: (1) stimulating keratinocyte cell-to-cell attachment; (2) accelerating reepithelialization; and (3) competing with the disease-causing pemphigus antibodies, preventing them from attachment to keratinocytes. Glucocorticosteroids and various types of steroid-sparing drugs used to treat pemphigus exhibit cholinergic side effects, including effects on expression and function of keratinocyte adhesion molecules, that are very similar to those produced by the cholinomimetic drugs. Further elucidation of the mechanisms underlying therapeutic efficacy of antiacantholytics may shed light on the immunopharmacological mechanisms of pemphigus antibody-induced acantholysis.

Abstract
Potassium channels constitute a superfamily of the most diversified ion channels, acting in delicate and accurate ways to control or modify many physiological and pathological functions including membrane excitability, transmitter release, cell proliferation and cell degeneration. The M-type channel is a unique ligand-regulated and voltage-gated K(+) channel showing distinct physiological and pharmacological characteristics. This review will cover some important progress in the study of M channel modulation, particularly focusing on membrane transduction mechanisms. The K(+) channel genes corresponding to the M channel have been identified and will be reviewed in detail. It has been a long journey since the discovery of M current in 1980 to our present understanding of the mysterious mechanisms for M channel modulation; a journey which exemplifies tremendous achievements in ion channel research and exciting discoveries of elaborate modulatory systems linked to these channels. While substantial evidence has accumulated, challenging questions remain to be answered.

Abstract
1. The role of cyclic ADP ribose and ryanodine receptors in the inhibition of the M-like current (IK(M,ng)) by acetylcholine was investigated in m1 muscarinic receptor-transformed mouse neuroblastoma-rat glioma hybrid (NG108-15) cells using patch-clamp techniques and calcium microfluorimetry. 2. Acetylcholine (1-100 microM) decreased IK(M,ng) by up to 55 %. Application, via the patch pipette, of the cyclic ADP ribose antagonists 8-amino-cyclic ADP ribose (10-100 microM) and 8-bromo-cyclic ADP ribose (100-1000 microM) reduced this inhibition of IK(M,ng) in a concentration-dependent manner. The half-maximal inhibition concentrations for 8-amino- cyclic ADP ribose and 8-bromo-cyclic ADP ribose were around 40 microM and 1 mM, respectively. 3. Neither of the cyclic ADP ribose antagonists altered the amplitude of IK(M,ng) per se, or the incidence of the concurrent Ca2+-activated K+ current (IIK(Ca)) activation, also mediated by acetylcholine. 4. The ryanodine receptor modulators ryanodine (1-10 microM) and Ruthenium Red (10 microM) did not alter IK(M,ng) amplitude or IK(M,ng) inhibition mediated by acetylcholine. There was a statistically significant increase in the proportion of cells showing outward currents in the presence of Ruthenium Red. 5. Intracellular calcium levels measured with fura-2 microfluorimetry were increased with low concentrations of ryanodine (1 microM), more consistently with caffeine (10 mM), and in almost every case with both bradykinin (300 nM) and acetylcholine (100 microM). Caffeine-, but not bradykinin-evoked responses were abolished by preincubation with ryanodine (10 microM). 6. The fast 'rundown rate' of the M-current recorded in rat superior cervical ganglion cells under whole-cell conditions precluded an investigation of the effects of intracellular dialysis of cyclic ADP ribose. However, when cyclic ADP ribose (5 microM) was applied directly to the cytoplasmic face of inside-out membrane patches excised from rat superior cervical ganglion cells containing M-channels, it had no effect on the main parameters of single channel activity (conductance, mean open time or frequency of opening). 7. These results indicate that cyclic ADP ribose acts on a specific intracellular site to mediate IK(M,ng) inhibition. However, unlike previously established effects of cyclic ADP ribose, the ryanodine receptor is not required, suggesting that another molecular target may be involved. Studies at the single channel level indicate that cyclic ADP ribose may not act directly on the M-channels in inside-out patches.

Abstract
U73122, a phospholipase C inhibitor, dose dependently blocks the cGMP-induced Ca2+ release in sea urchin eggs and homogenates. U73122 inhibition was prevented by cotreatment with dithiothreitol (DTT), but DTT is ineffective when eggs or homogenates were pretreated with U73122. U73122 action is different from the other sulfhydryl reagents, thimerosal and N-ethylmaleimide, which cause Ca2+ release in egg homogenates at high concentration, but at lower concentration have no significant effect on cGMP-induced Ca2+ release. Histone, a reported NAD glycohydrolase (NADase) activator, was found to induce Ca2+ release in egg homogenates via the same pathway as the cGMP response, since histone-induced Ca2+ release is blocked by Rp-8-pCPT-cGMPS, a cGMP-dependent protein kinase (PKG) inhibitor, and nicotinamide, a NADase inhibitor. Histone-induced Ca2+ release is similarly blocked by U73122. The aminosteroid U73122 does not inhibit cADPR-induced Ca2+ release, which is significantly reduced by PKG inhibitors. Furthermore, U73122 has no significant effect on phorbol 12-myristate 13-acetate induced-cytoplasmic alkalinization in intact eggs, which depends on protein kinase C activity. These results suggest that U73122 does not act as a general serine-threonine protein kinase inhibitor, and the aminosteroid inhibition of the cGMP-induced Ca2+ release may interfere with ADP ribosyl cyclase activity.

Abstract
Cyclic ADP-ribose (cADP-ribose) is an endogenous modulator of ryanodine-sensitive Ca2+ release channels. An unsolved question is whether or not cADP-ribose mediates intracellular signals from hormone or neurotransmitter receptors. The first step in this study was to develop a TLC method to measure ADP-ribosyl cyclase, by which conversion of [3H]NAD+ to [3H]cADP-ribose was confirmed in COS-7 cells overexpressing human CD38. A membrane fraction of NG108-15 neuroblastoma x glioma hybrid cells possessed ADP-ribosyl cyclase activity measured by TLC. Carbamylcholine increased this activity by 2.6-fold in NG108-15 cells overexpressing m1 or m3 muscarinic acetylcholine receptors (mAChRs), but inhibited it by 30-52% in cells expressing m2 and/or m4 mAChRs. Both of these effects were mimicked by GTP. Pretreatment of cells with cholera toxin blocked the activation, whereas pertussis toxin blocked the inhibition. Application of carbamylcholine caused significant decreases in NAD+ concentrations in untreated m1-transformed NG108-15 cells, but an increase in cholera toxin-treated cells. These results suggest that mAChRs couple to ADP-ribosyl cyclase within cell membranes via trimeric G proteins and can thereby control cellular function by regulating cADP-ribose formation.

Abstract
1. Bradykinin has multiple effects on differentiated NG108-15 neuroblastoma x glioma cells: it increases Ins(1,4,5)P3 production and intracellular Ca2+ concentration [Ca2+]i evokes a Ca2+ activated K+ current (IK(Ca)) and inhibits M current (IM). We studied the effect of the aminosteroid U73122 and the antibiotic neomycin, both putative blockers of phospholipase C (PLC), on these four bradykinin effects. 2. Preincubation with 1 or 5 microM U73122 for 15 min partly suppressed Ins(1,4,5)P3 generation and the increase in [Ca2+]i induced by 1 microM bradykinin. U73122 10 microM caused total and irreversible inhibition. The inactive analogue U73343 was without effect. 3. Resting levels of Ins(1,4,5)P3 were not affected. However, resting [Ca2+]i was increased by 10 microM U73122, but not by U73343. Individual cells responded to 10 microM U73122 with a small increase in [Ca2+]i, followed in some cells by a large further rise. 4. Pretreatment of whole-cell clamped cells with 1 microM U73122 for 30 min reduced the bradykinin-induced IK(Ca) to a fifth of its normal size. To suppress it totally, a 7-12 min pretreatment with 5 microM U73122 was required. Again, U73343 was without effect. 5. U73122 and U73343 at concentrations of 5-10 microM irreversibly decreased the holding current (Ih) which at a holding potential of -30 or -20 mV mainly flows through open M channels. The decrease was often preceded by a transient increase. 6. M current (IM) measured with 1 s pulses, was also decreased by 5-10 microM U73122 and U73343, but short applications of U73122 could cause a small increase. The bradykinin-induced inhibition of IM was not affected by U73122. 7. Preincubation with 1 or 3 mM neomycin for 15 min did not affect Ins(1,4,5)P3 generation and the increase in [Ca2+]i induced by bradykinin. Pretreatment with 3 mM neomycin for about 20 min diminished the bradykinin-induced IK(Ca) to a fifth of its normal size. 8. The four main conclusions drawn from the results are: (a) U73122 suppresses bradykinin-induced PLC activation and IK(Ca), but not IM inhibition. (b) This indicates that the transient outward current IK(Ca), but not the decrease of IM in response to bradykinin, is mediated by PLC. (c) U73122 itself inhibits IM and mobilizes Ca2+ from intracellular stores. (d) Externally applied neomycin is not an effective inhibitor of PLC-mediated signalling pathways in NG108-15 cells.

Abstract
Cyclic ADP ribose (cADPR) is a potent Ca(2+)-releasing agent, and putative second messenger, the endogenous levels of which are tightly regulated by synthetic (ADP-ribosyl cyclases) and degradative (cADPR hydrolase) enzymes. These enzymes have been characterized in a number of mammalian and invertebrate tissues and their activities are often found on a single polypeptide. beta-NAD+, cGMP and nitric oxide (NO) have been reported to mobilize Ca2+ in the sea urchin egg via the cADPR-mediated pathway. We now report that in sea urchin egg homogenates, nicotinamide inhibits the Ca(2+)-mobilizing action of beta-NAD+, cGMP and NO, but has no effect on cADPR-induced Ca2+ release. Moreover, nicotinamide inhibits cGMP-induced regenerative Ca2+ waves in the intact sea urchin egg. By successfully separating the cADPR-metabolizing machinery from that which releases Ca2+, we have shown that nicotinamide inhibits cADPR-mediated Ca2+ signalling at the level of cADPR generation. Importantly, nicotinamide had no effect upon the hydrolysis of cADPR, and its selective action on cyclase activity was supported by its inhibition of purified Aplysia ADP-ribosyl cyclase, which does not exhibit detectable hydrolytic activity. The action of nicotinamide in blocking Ca2+ release by beta-NAD+, cGMP and NO strongly suggests that these agents act as modulators of cADPR synthesis rather than to sensitize calcium release channels to cADPR.
