Interruption of transmembrane signaling as a novel antisecretory strategy to treat enterotoxigenic diarrhea. (1/208)

Bacteria that produce heat-stable enterotoxins (STs), a leading cause of secretory diarrhea, are a major cause of morbidity and mortality worldwide. ST stimulates guanylyl cyclase C (GCC) and accumulation of intracellular cyclic GMP ([cGMP]i), which opens the cystic fibrosis transmembrane conductance regulator (CFTR)-related chloride channel, triggering intestinal secretion. Although the signaling cascade mediating ST-induced diarrhea is well characterized, antisecretory therapy targeting this pathway has not been developed. 2-ChloroATP (2ClATP) and its cell-permeant precursor, 2-chloroadenosine (2ClAdo), disrupt ST-dependent signaling in intestinal cells. However, whether the ability to disrupt guanylyl cyclase signaling translates into effective antisecretory therapy remains untested. In this study, the efficacy of 2ClAdo to prevent ST-induced water secretion by human intestinal cells was examined. In Caco-2 human intestinal cells, ST increased [cGMP]i, induced a chloride current, and stimulated net basolateral-to-apical water secretion. This effect on chloride current and water secretion was mimicked by the cell-permeant analog of cGMP, 8-bromo-cGMP. Treatment of Caco-2 cells with 2ClAdo prevented ST-induced increases in [cGMP]i, chloride current and water secretion. Inhibition of the downstream consequences of ST-GCC interaction reflects proximal disruption of cGMP production because 8-bromo-cGMP stimulated chloride current and water secretion in 2ClAdo-treated cells. Thus, this study demonstrates that disruption of guanylyl cyclase signaling is an effective strategy for antisecretory therapy and provides the basis for developing mechanism-based treatments for enterotoxigenic diarrhea.  (+info)

Depletion of alveolar macrophages by treatment with 2-chloroadenosine aerosol. (2/208)

Alveolar macrophages (AMs) are localized in the alveoli and alveolar ducts of the lung and are the only macrophages living in an aerobic environment. Recent studies have demonstrated that AMs play a central role in lung diseases, such as pneumonia and acute respiratory distress syndrome. It has become important to find a simple, effective way to eliminate AMs in order to investigate the function of AMs in vivo. 2-Chloroadenosine (2-CA), a purine analog, is reported to be selectively cytotoxic to cultured macrophages, and we hypothesized that it would deplete the number of AMs in the bronchoalveolar lavage fluid (BALF) of mice without any effect on neutrophil or lymphocyte counts. After mice had inhaled 1 mM aerosolized 2-CA for 2 h, AMs were found to be significantly depleted at 0 h [(4.42 +/- 0.16) x 10(4)/ml], 24 h [(4.17 +/- 0.89) x 10(4)/ml], 48 h [(3.17 +/- 0.21) x 10(4)/ml], and 72 h [(5.00 +/- 0.64) x 10(4)/ml] compared with concentrations in untreated controls [(12.1 +/- 0.21) x 10(4)/ml]. Neutrophil and lymphocyte counts in BALF did not change and histological changes in the lung were not observed after 2-CA treatment. The lung wet-to-dry weight ratio did not change at 0, 24, and 48 h after 2-CA aerosol application. The 2-CA aerosol had no effect on lung vascular permeability, as assessed by the intravenous administration of Evans blue, or on other phagocytes, as assessed by Kupffer cell counts. Our study demonstrates the efficacy of 2-CA in reducing AM numbers in vivo.  (+info)

A(2B) receptors mediate antimitogenesis in vascular smooth muscle cells. (3/208)

Adenosine inhibits growth of vascular smooth muscle cells. The goals of this study were to determine which adenosine receptor subtype mediates the antimitogenic effects of adenosine and to investigate the signal transduction mechanisms involved. In rat aortic vascular smooth muscle cells, platelet-derived growth factor-BB (PDGF-BB) (25 ng/mL) stimulated DNA synthesis ([(3)H]thymidine incorporation), cellular proliferation (cell number), collagen synthesis ([(3)H]proline incorporation), total protein synthesis ([(3)H]leucine incorporation), and mitogen-activated protein (MAP) kinase activity. The adenosine receptor agonists 2-chloroadenosine and 5'-N-methylcarboxamidoadenosine, but not N(6)-cyclopentyladenosine or CGS21680, inhibited the growth effects of PDGF-BB, an agonist profile consistent with an A(2B) receptor-mediated effect. The adenosine receptor antagonists KF17837 and 1,3-dipropyl-8-p-sulfophenylxanthine, but not 8-cyclopentyl-1, 3-dipropylxanthine, blocked the growth-inhibitory effects of 2-chloroadenosine and 5'-N-methylcarboxamidoadenosine, an antagonist profile consistent with an A(2) receptor-mediated effect. Antisense, but not sense or scrambled, oligonucleotides to the A(2B) receptor stimulated basal and PDGF-induced DNA synthesis, cell proliferation, and MAP kinase activity. Moreover, the growth-inhibitory effects of 2-chloroadenosine, 5'-N-methylcarboxamidoadenosine, and erythro-9-(2-hydroxy-3-nonyl) adenine plus iodotubericidin (inhibitors of adenosine deaminase and adenosine kinase, respectively) were abolished by antisense, but not scrambled or sense, oligonucleotides to the A(2B) receptor. Our findings strongly support the hypothesis that adenosine causes inhibition of vascular smooth muscle cell growth by activating A(2B) receptors coupled to inhibition of MAP kinase activity. Pharmacological or molecular biological activation of A(2B) receptors may prevent vascular remodeling associated with hypertension, atherosclerosis, and restenosis following balloon angioplasty.  (+info)

Altered regulation of potassium and calcium channels by GABA(B) and adenosine receptors in hippocampal neurons from mice lacking Galpha(o). (4/208)

To examine the role of G(o) in modulation of ion channels by neurotransmitter receptors, we characterized modulation of ionic currents in hippocampal CA3 neurons from mice lacking both isoforms of Galpha(o). In CA3 neurons from Galpha(o)(-/-) mice, 2-chloro-adenosine and the GABA(B)-receptor agonist baclofen activated inwardly rectifying K(+) currents and inhibited voltage-dependent Ca(2+) currents just as effectively as in Galpha(o)(+/+) littermates. However, the kinetics of transmitter action were dramatically altered in Galpha(o)(-/-) mice in that recovery on washout of agonist was much slower. For example, recovery from 2-chloro-adenosine inhibition of calcium current was more than fourfold slower in neurons from Galpha(o)(-/-) mice [time constant of 12.0 +/- 0.8 (SE) s] than in neurons from Galpha(o)(+/+) mice (time constant of 2.6 +/- 0.2 s). Recovery from baclofen effects was affected similarly. In neurons from control mice, effects of both baclofen and 2-chloro-adenosine on Ca(2+) currents and K(+) currents were abolished by brief exposure to external N-ethyl-maleimide (NEM). In neurons lacking Galpha(o), some inhibition of Ca(2+) currents by baclofen remained after NEM treatment, whereas baclofen activation of K(+) currents and both effects of 2-chloro-adenosine were abolished. These results show that modulation of Ca(2+) and K(+) currents by G protein-coupled receptors in hippocampal neurons does not have an absolute requirement for Galpha(o). However, modulation is changed in the absence of Galpha(o) in having much slower recovery kinetics. A likely possibility is that the very abundant Galpha(o) is normally used but, when absent, can readily be replaced by G proteins with different properties.  (+info)

Possible role of immune surveillance at the initial phase of metastasis produced by B16BL6 melanoma cells. (5/208)

The relationship among the real-time trafficking of lung metastatic B16BL6 cells, metastatic potential, and the injected number of the cells was examined, since the smaller the number of tumor cells injected, the more clearly the immune defense may be observed. When 1x10(6) or 1x10(5) B16BL6 cells were injected into mice via the tail vein, both numbers of cells accumulated in the lung at a similar rate: there was an approximately 10-fold difference in the number of accumulated cells between the two doses. Elimination from the lung was not dependent on the cell number but on the proportion of accumulated cells. However, the injection of 1x10(4) cells resulted in lung accumulation less than one-tenth of that obtained with 1x10(5) cell injection. Metastasis was observed when 1x10(5) or 1x10(6) B16BL6 cells were injected, but not after injection of 1x10(4) cells. To clarify the roles of the immune defense system at the initial phase of metastasis, we challenged macrophage-depleted mice with 1x10(4) tumor cells. Treatment of mice with 2-chloroadenosine prior to the tumor cell challenge cancelled the suppression of not only metastasis but also the lung accumulation. Furthermore, the administration of 2-chloroadenosine following the tumor cell challenge had little effect on the metastatic potential. These results suggest that the immune surveillance whose action was obvious at the low dose of challenged tumor cells functions strongly at the initial phase but not at the advanced stages of the metastatic process, and that macrophages play an important role in the suppression of metastasis.  (+info)

Adenosine A(2A) and A(2B) receptors in cultured human and porcine coronary artery endothelial cells. (6/208)

We investigated the role of the cAMP link to the signal transduction mechanism coupled with adenosine A(2A) and A(2B) receptors in cultured human coronary artery endothelial cells (HCAEC) and porcine coronary artery endothelial cells (PCAEC). 2-[4-[2- inverted question mark2-[(4-aminophenyl)methylcarbonylamino]ethylaminocarbon yl inverted question marketh yl]phenyl]ethylamino-5'- ethylcarboxamidoadenosine ((125)I-PAPA-APEC) (PAPA-APEC) was used to demonstrate the specific binding in PCAEC membranes. The specific binding was saturable and reversible with a maximal number of binding sites (B(max)) of 240 fmol/mg protein, and scatchard analysis revealed a single class of binding site with an equilibrium dissociation constant (K(d)) of 1. 17 +/- 0.035 nM. In competition experiments, adenosine receptor agonists showed the following order of potency (based on IC(50)): 5'-(N-ethylcarboxamido)adenosine (NECA) >/= CGS-21680 > 2-chloroadenosine. This order appears to be consistent with the A(2) adenosine receptor classification. We also studied the effects of adenosine agonists on the accumulation of cAMP as an indirect approach to show the presence of functional A(2) receptors. Similarly, the same adenosine agonists (10(-7)-10(-4) M) elicited the production of cAMP in intact endothelial cells in a dose-dependent manner, exhibiting consistently with the A(2) adenosine receptor classification. A selective A(2A) adenosine receptor antagonist (ZM-241385, 10(-8) M) significantly inhibited the effect of CGS-21680 on cAMP but only partly inhibited the effect of NECA, suggesting the presence of both A(2A) and A(2B) receptors. Western blot analysis further showed the immunoreactivity of A(2A) and A(2B) receptor at 45 and 36 kDa, respectively, in both HCAEC and PCAEC. Direct evidence for the presence of A(2A) and A(2B) receptors in cultured HCAEC and PCAEC by reverse transcription-polymerase chain reaction (RT-PCR), revealed expected PCR product sizes (205 and 173 bp) for A(2A) and A(2B) receptors in HCAEC and PCAEC, respectively. The data show that adenylate cyclase-coupled adenosine A(2A) and A(2B) receptors are present in coronary endothelial cells.  (+info)

Selective transport of adenosine into porcine coronary smooth muscle. (7/208)

Adenosine (ADO), an endogenous regulator of coronary vascular tone, enhances vasorelaxation in the presence of nucleoside transport inhibitors such as dipyridamole. We tested the hypothesis that coronary smooth muscle (CSM) contains a high-affinity transporter for ADO. ADO-mediated relaxation of isolated large and small porcine coronary artery rings was enhanced 12-fold and 3.4-fold, respectively, by the transport inhibitor, S-(4-nitrobenzyl)-6-thioinosine (NBTI). Enhanced relaxation was independent of endothelium and was selective for ADO over synthetic analogs. Uptake of [(3)H]ADO into freshly dissociated CSM cells or endothelium-denuded rings was linear and concentration dependent. Kinetic analysis yielded a maximum uptake (V(max)) of 67 +/- 7.0 pmol. mg protein(-1). min(-1) and a Michaelis constant (K(m)) of 10. 5 +/- 5.8 microM in isolated cells and a V(max) of 5.1 +/- 0.5 pmol. min(-1). mg wet wt(-1) and a K(m) of 17.6 +/- 2.6 microM in intact rings. NBTI inhibited transport into small arteries (IC(50) = 42 nM) and cells. Analyses of extracellular space and diffusion kinetics using [(3)H]sucrose indicate the V(max) and K(m) for ADO transport are sufficient to clear a significant amount of extracellular adenosine. These data indicate CSM possess a high-affinity nucleoside transporter and that the activity of this transporter is sufficient to modulate ADO sensitivity of large and small coronary arteries.  (+info)

A1 adenosine receptors inhibit multiple voltage-gated Ca2+ channel subtypes in acutely isolated rat basolateral amygdala neurons. (8/208)

1. The anticonvulsant properties of 2-chloroadenosine (CADO) in the basolateral amygdala rely on the activation of adenosine-specific heptahelical receptors. We have utilized whole-cell voltage-clamp electrophysiology to examine the modulatory effects of CADO and other adenosine receptor agonists on voltage-gated calcium channels in dissociated basolateral amygdala neurons. 2. CADO, adenosine, and the A1 subtype-selective agonists N6-(L-2-Phenylisopropyl)adenosine (R-PIA) and 2-chloro-N6-cyclopentyladenosine (CCPA) reversibly modulated whole cell Ba2+ currents in a concentration-dependent fashion. CADO inhibition of barium currents was also sensitive to the A1 antagonist 1,3-dipropyl-8-cyclopentylxanthine (DPCPX). 3. The A2A-selective agonist 4-[2-[[6-Amino-9-(N-ethyl-beta-D-ribofuranuronamidosyl)-9H-purin-2-yl]amino]ethyl ]benzenepropanoic acid (CGS21680) was without effect. 4. CADO inhibition was predominantly voltage-dependent and sensitive to the sulphydryl-modifying reagent N:-ethylmaleimide, implicating a membrane-delimited, G(i/o)-coupled signal transduction pathway in the channel regulation. 5. Using Ca2+ channel subtype-selective antagonists, CADO inhibition appeared to target multiple channel subtypes, with the inhibition of omega-conotoxin GVIA-sensitive calcium channels being more prominent. 6. Our results indicate that the anti-convulsant effects CADO in the basolateral amygdala may be mediated, in part, by the A1 receptor-dependent inhibition of voltage gated calcium channels.  (+info)

The nucleoside analogues 8-amino-adenosine and 8-chloro-adenosine have been investigated in the context of B-lineage lymphoid malignancies by our laboratories because of the selective cytotoxicity they exhibit toward multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and mantle cell lymphoma (MCL) cell lines and primary cells. personal of seven exclusive genes including which encodes the rate-determining enzyme from the pentose phosphate pathway (PPP), blood sugar-6-phosphate dehydrogenase. Bioinformatic evaluation of major cell gene manifestation data proven that G6PD is generally overexpressed in CLL and MM, highlighting the clinical implications of the finding. Using the combined resistant and delicate MM and MCL cell lines like a model program, we continue to show through loss-of-function and gain-of-function research that raised G6PD manifestation is necessary to keep up level of resistance to 8-amino- and 8-chloro-adenosine but inadequate to induce level of resistance in delicate ...

The involvement of a guanine-nucleotide-binding regulatory protein (G protein) in the relaxing responses to adenosine receptor agonists was investigated in bovine coronary vessels. Ring segments of left anterior descending artery branches were suspended in organ baths for measurement of isometric tension. The adenosine analogs, 5-N-ethylcarboxamidoadenosine (NECA) and 2-chloroadenosine (CAD) caused concentration-dependent relaxations of coronary rings contracted with KCl. The relaxing effects of NECA and CAD were antagonized by the adenosine receptor antagonist 8-phenyltheophylline indicating the involvement of an adenosine receptor. In a separate series of experiments, incubation with cholera toxin inhibited the relaxing responses to NECA, CAD and isoproterenol but not those produced by sodium nitroprusside. Treatment with forskolin did not reduce the relaxing responses to NECA or CAD. N-ethylmaleimide and NaF/AlCl3 caused significant inhibition of the relaxations produced by both NECA and ...
BACKGROUND: Epidermal keratinocytes continuously proliferate and differentiate to form the mechanical and water permeability barrier that makes terrestrial life possible. In certain skin diseases, these processes become dysregulated, resulting in abnormal barrier formation. In particular, skin diseases such as psoriasis, actinic keratosis and basal and squamous cell carcinomas are characterized by hyperproliferation and aberrant or absent differentiation of epidermal keratinocytes. We previously demonstrated that 8-Cl-adenosine (8-Cl-Ado) can induce keratinocyte growth arrest without inducing differentiation. RESULTS: To determine if this agent might be useful in treating hyperproliferative skin disorders, we investigated whether 8-Cl-Ado could enhance the ability of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], a known keratinocyte differentiating agent and a clinical treatment for psoriasis, to inhibit keratinocyte growth. We found that low concentrations of 8-Cl-Ado and 1,25(OH)2D3 appeared to act ...

Deliberate hypotension is defined as lowering the systolic blood pressure to 80-90mmHg, or the mean blood pressure to 50-65mmHg. This technique is usually employed for operations that have a high risk of intraoperative hemorrhage, such as orthognathic surgery. Several different regimens are used to lower the patients blood pressure, such as vasodilators, autonomic nervous system inhibitors, opioids and inhalation anesthetics. However, the effects that these agents have on the QTc and Tp-e intervals during deliberate hypotension is not known. Virtually every kind of anesthetic is reported to have some effect on the QTc and Tp-e intervals. Because orthognathic surgery usually takes 3-4 hours to complete, the amount of anesthetics and drugs used to maintain low blood pressure is not small. Therefore, the effect that these agents may have on the QTc and Tp-e intervals may not be negligible. The investigators of the present study found that the high dose of commonly used hypotensive agents tend to ...
Cyclic 3, 5-[14C]AMP was measured in platelets that had first been incubated with [14C]adenine. Maximum increases of 2-4-fold were observed 0.5 min after addition of 10-40 µM adenosine. Smaller increases were obtained with higher concentrations of adenosine. In 0.5-min incubations 2-chloroadenosine was less effective than adenosine at concentrations below 20 µM and more effective at concentrations above 100 µM. Incorporation of 1-10 µM adenosine into platelets was inhibited at least 96% by p-nitrobenzylthioguanosine without any effect on the increase in cyclic [14C]AMP caused by these concentrations of adenosine, suggesting that adenosine acts at an extracellular site. With higher adenosine concentrations, p-nitrobenzylthioguanosine was less effective in inhibiting incorporation of adenosine but blocked the decline in cyclic [14C]AMP levels observed on increasing the adenosine concentration above 40 µM. This inhibitory effect of high adenosine concentrations on the accumulation of cyclic ...

OBJECTIVE: Adenosine deaminase (ADA) may be multifunctional, regulating adenosine levels and adenosine receptor (AR) agonism, and potentially modifying AR functionality. Herein we assess effects of ADA (and A(1)AR) deficiency on AR-mediated responses and ischaemic tolerance. METHODS: Normoxic function and responses to 20 or 25min ischaemia and 45min reperfusion were studied in isolated hearts from wild-type mice and from mice deficient in ADA and/or A(1)ARs. RESULTS: Neither ADA or A(1)AR deficiency significantly modified basal contractility, although ADA deficiency reduced resting heart rate (an effect abrogated by A(1)AR deficiency). Bradycardia and vasodilation in response to AR agonism (2-chloroadenosine) were unaltered by ADA deficiency, while A(1)AR deficiency eliminated the heart rate response. Adenosine efflux increased 10- to 20-fold with ADA deficiency (at the expense of inosine). Deletion of ADA improved outcome from 25min ischaemia, reducing ventricular diastolic pressure (by 45%; ...
1. Noradrenaline and histamine, when added to superfused guinea-pig cerebral-cortical tissues, increased both cyclic AMP-dependent and -independent histone kinase activities of some, but not of all, subsequently isolated subcellular fractions, and decreased their cyclic [3H]AMP-binding capacity, which was concluded to be due to an increase in endogenously bound cyclic AMP. 2. Adenosine and 2-chloroadenosine also diminished the cyclic [3H]AMP-binding capacities, but did not affect the histone kinase activities. 3. DEAE-cellulose chromatography and stability to KCl additions showed that the greater part of the histone kinase of the present preparations corresponded to the type II enzyme [of Corbin, Keely & Park (1975) J. Biol. Chem. 250, 218-225], with a lesser amount of type I activity. Different sites of cyclic AMP accumulation in relation to these or other kinases are considered in interpreting the differential tissue responses to the neurohumoural agents examined.. ...
Rat islets were used to compare the mechanisms whereby adenosine and adrenaline inhibit insulin release. Adenosine (1 microM-2.5 mM) and its analogue N6(-)-phenylisopropyladenosine (L-PIA) (1 nM-10 microM) caused a concentration-dependent but incomplete (45-60%) inhibition of glucose-stimulated release. L-PIA was more potent than D-PIA [the N6(+) analogue], but much less than adrenaline, which caused nearly complete inhibition (85% at 0.1 microM). 8-Phenyltheophylline prevented the inhibitory effect of L-PIA and 50 microM-adenosine, but not that of 500 microM-adenosine or of adrenaline. In contrast, yohimbine selectively prevented the inhibition by adrenaline. Adenosine and L-PIA thus appear to exert their effects by activating membrane A1 receptors, whereas adrenaline acts on alpha 2-adrenergic receptors. Adenosine, L-PIA and adrenaline slightly inhibited 45Ca2+ efflux, 86Rb+ efflux and 45Ca2+ influx in glucose-stimulated islets. The inhibition of insulin release by adenosine or L-PIA was ...

TY - JOUR. T1 - Alterations in cyclic AMP generation and G protein subunits following transient ischemia in gerbil hippocampus. AU - Suyama, Kazuhiko. AU - Saito, Kuniaki. AU - Chen, Guang. AU - Pan, Bai Shen. AU - Manji, Husseini K.. AU - Potter, William Z.. PY - 1995. Y1 - 1995. N2 - We examined alterations in the cyclic AMP generating system and G protein subunits in gerbil hippocampus following 10 min of transient ischemia. In hippocampal slices, basal and isoproterenol- and forskolin-stimulated cyclic AMP accumulations were markedly increased at 6 and 24 h after ischemia. Interestingly, both the inhibition of forskolin-stimulated cyclic AMP and the potentiation of β-adrenoceptor-stimulated cyclic AMP by a γ-aminobutyric acid(B) receptor agonist were attenuated at these time points. Ischemia did not affect the immunolabeling of any of the G protein α subunits; only that of β subunits was significantly decreased, by 28.2%, 4 days after ischemia. In contrast, pertussis toxin-catalyzed ...

Professor Strickler really knows how to put us under stress during rapid-fire brainstorming sessions, Cado said. On top of that, shes helped us develop the empathy it takes to build a product for customers based on their needs..

We retrospectively identified 17 pediatric LCH patients treated with 2-CdA. All patients were refractory or reactivated cases who had been initially treated according to the JLSG-02 protocol of the Japan LCH study group. At initiation of 2-CdA therapy, 4 patients had primary refractory multisystem (MS) disease with risk organ (RO) involvement (MS?), 9 patients had reactivated MS disease [5 MS+ and 4 without RO involvement ...
Afferent chemoreceptor activity was recorded from the peripheral cut end of the carotid sinus nerve in pentobarbitone anaesthetized cats. The effects of purines, peptides and ouabain on chemosensory activity were studied. Purines. It was found that intracarotid injections of adenosine: AMP; ADP; ATP; CoA;Me-adenosine analogues: N6-methyladenosine, 2-chloroadenosine, 3-deoxyudenosine but not 2-deoxyadenosine; cyclic AMP; dibutyryl cyclic AMP increased spontaneous chemoreceptor discharge. The ATP analogues, a-5- methylene ATP decreased spontaneous chemoreceptor discharge, whereas the f-y-methylene ATP caused a slight increase in discharge. Adenine and the purine nucleosides inosine and guanosine had little or no effect on the discharge. The pyrimidine nucleosides cytidine and uridine were also studied and had little or no effect on spontaneous chemoreceptor discharge. Intracarotid injection of theophylline transiently depressed spontaneous chemosensory activity and potentiated the action of ...
The initial therapies of choice for hairy cell leukemia are either cladribine (2-chlorodeoxyadenosine, 2-CdA) or pentostatin. [1] [2] These drugs have comparable response rates but have not been compared in phase III trials. Cladribine is administered as a one-time continuous infusion or series of subcutaneous injections and is associated with a high rate of febrile neutropenia. [3] [4] [5] [6] Rarely, more than one course of treatment is required to induce a desirable response. Treatment should be discontinued once complete remission or stable partial remission with normalization of peripheral blood counts is reached. The presence of residual disease may be predictive of relapse but does not seem to affect survival. [5] [7] The role of consolidation or maintenance therapy in preventing relapse or progression of the disease after treatment with purine analogs has not been evaluated and remains unproven. Pentostatin is administered intermittently for a longer time but may result in a lower ...
