More specifically, this application is directed to various forms of the dilactate salt of squalamine and their utility in inhibiting neovascularization and endothelial ce...

Many therapies designed to reduce food intake and body weight act, in part, by blocking the dopamine transporter (DAT) - a protein responsible for clearing extracellular dopamine (DA) after release thereby terminating its action. Here, we found that a single injection of the drug trodusquemine (MSI-1436) decreased food intake in rats. To assess the...

Trodusquemine (MSI-1436) causes rapid and reversible weight loss in genetic models of obesity. To better predict the potential effects of trodusquemine in the clinic, we investigated the effects of trodusquemine treatment in a murine model of diet-induced obesity (DIO). Trodusquemine suppressed appetite, reduced body weight (BW) in a fat-specific m...

We have previously shown that expression of a Ca2+-activated Cl− channel (mCLCA3 in mice and hCLCA1 in humans) is up-regulated along with goblet cell metaplasia and mucus overproduction in the lungs of interleukin 9 (IL9) transgenic mice, and in human primary lung cultures by IL4, IL13 and IL9. We show here that hCLCA1 expression in NCI-H292 cells...

Twenty anesthetized male Brown-Norway rats received a series of 8 krypton red laser lesions...

Interleukin-9 (IL-9) has been strongly implicated in the pathogenesis of asthma, including the overproduction of mucus, in humans and in animal models. We evaluated the inflammatory changes associated with the upregulation of mucus production by examining the time course of inflammation after daily intratracheal IL-9 administration to naive C57Bl6...

We have previously shown that expression of a Ca2+-activated Cl- channel (mCLCA3 in mice and bCLCA1 in humans) is up-regulated along with goblet cell metaplasia and mucus overproduction in the lungs of interleukin 9 (IL9) transgenic mice, and in human primary lung cultures by IL4, IL13 and IL9. We show here that hCLCA1 expression in NCI-H292 cells...

It is now generally well accepted that atopic asthma is a complex heritable disorder of the airways in which symptoms depend on environmental exposure [1]. This lung disorder is associated with clinical signs and symptoms of airway hyperresponsiveness (AHR), an exaggerated narrowing of the airways to provocative stimuli, and eosinophilic inflammat...

Interleukin (IL)-9 is a T helper (Th) 2 cytokine recently implicated as an essential factor in determining susceptibility to asthma. Transgenic mice overexpressing IL-9 exhibit many features that are characteristic of human asthma. To better understand the mechanism by which IL-9 mediates the various biologic activities in asthma, we performed supp...

We describe the pharmacological properties of a novel spermine-cholesterol adduct, MSI 1436 (3beta-N-1(spermine)-7alpha, 24R-dihydroxy-5alpha-cholestane 24-sulfate), which causes reversible suppression of food and fluid intake in mammals resulting in profound weight loss, not associated with other signs or symptoms of illness, and which exhibits an...

Squalamine, an antiangiogenic aminosterol, is presently undergoing Phase II clinical trials in cancer patients. To broaden our understanding of the clinical potential for squalamine, this agent was evaluated in nu/nu mouse xenograft models using the chemoresistant MV-522 human non-small cell lung carcinoma and the SD human neuroblastoma lines. Squa...

Asthma is a complex heritable inflammatory disorder of the airways in which the development of clinical disease depends on environmental exposure. It has been well established that T helper type 2 (TH2) lymphocytes and their cytokines have an important role in allergic asthma. Interleukin (IL)-9, a member of the TH2 cytokine family, has recently be...

Asthma is a complex heritable inflammatory disorder of the airways associated with clinical signs of allergic inflammation and bronchial hyperresponsiveness (BHR). The incidence of asthma continues to rise in industrialized countries despite advances in the identification of cellular and molecular mediators that are associated with the disease. Bec...

Human atopic asthma is a complex heritable inflammatory disorder of the airways associated with clinical signs of allergic inflammation and airway hyperresponsiveness. Recent studies demonstrate that the degree of airway responsiveness is strongly associated with interleukin (IL)-9 expression in murine lung. To investigate the contribution of IL-9...

The novel aminosterol, squalamine, inhibits angiogenesis and tumor growth in multiple animal models. This effect is mediated, at least in part, by blocking mitogen-induced proliferation and migration of endothelial cells, thus preventing neovascularization of the tumor. Squalamine has no observable effect on unstimulated endothelial cells, is not d...

We have demonstrated that adenosine enhances insulin-stimulated myocardial glucose uptake in situ. In the present study we determined the role of adrenergic influences and myocardial work on insulin-stimulated myocardial glucose uptake while varying intracoronary adenosine concentrations. Under pentobarbital anesthesia we instrumented mongrel dogs...

The medical community has not yet identified cerebrovascular pathophysiological factors that distinguish patients at high risk for stroke or aid in selecting patients for microvascular cerebral bypass. In this study, we describe the courses of 13 patients, all of whom suffered recurrent episodes of transient cerebral ischemia after previous cerebra...

Disturbances in normal glucose metabolism and homeostasis which manifest as hyperglycemia and glucose intolerance are often observed during clinical sepsis. Skeletal and myocardial muscle as well as whole body insulin resistance have been demonstrated in this laboratory and others during experimental and clinical sepsis. The existence of hepatic in...

Diabetic patients exhibit a higher incidence of post-surgical sepsis, as well as a higher rate of mortality from sepsis, than their non-diabetic counterparts. This may be a result of cardiovascular deterioration associated with diabetes mellitus. This study was designed to characterize the cardiovascular sequelae associated with endotoxin shock in...

Better understood in other tissues, the effects of adenosine on insulin-stimulated glucose uptake in the heart are poorly understood. Under pentobarbital anesthesia, we instrumented mongrel dogs to obtain general hemodynamics (blood pressure and heart rate), and arterial and coronary sinus blood samples for measuring oxygen and glucose concentratio...

Glucose dyshomeostasis and insulin resistance are well-documented characteristics of sepsis. The insulin resistance could be manifested in a decreased peripheral glucose uptake and/or an increased hepatic glucose output. To investigate the hepatic and peripheral responses to insulin in a three-day model of sepsis, 14 mongrel dogs were studied. Anim...

In vitro investigations have indicated that adenosine can inhibit beta adrenergic stimulated increases in cardiac contractility. The present study was designed to determine the ability of adenosine to inhibit isoprenaline induced increases in contractility in vivo. Adenosine has been reported to exert its inhibitory effects on contractility by inhi...

Modulation by adenosine of hepatic responsiveness to insulin was investigated in vivo in 10 healthy mongrel dogs of both sexes by determining net hepatic glucose output (NHGO) in response to insulin during the presence or absence of exogenous adenosine infusion. In addition, two separate series of experiments were performed to study the effect of a...

Study objective – Catecholamine concentrations are raised during endotoxin shock and may be responsible for myocardial insulin resistance in such a condition. The purpose of the investigation was to examine the effect of insulin on myocardial contractility and glucose uptake in the presence of β adrenergic blockade during endotoxin shock. Design –...

We recently reported that adenosine potentiated insulin-stimulated myocardial glucose uptake (MGU) in vivo and that adenosine receptor blockade resulted in myocardial insulin resistance. Since myocardial insulin resistance has been reported to occur during endotoxin shock, we decided to investigate whether infusion of adenosine could ameliorate thi...

Myocardial insulin responsiveness was determined in open-chest pentobarbital sodium-anesthetized dogs before and after endotoxin administration. Animals were instrumented to measure mean arterial blood pressure (MABP), heart rate (HR), and coronary blood flow. Myocardial glucose uptake and myocardial oxygen uptake (MVO2) were determined during a ba...

During endotoxin shock the heart becomes less responsive to the stimulatory effect of insulin on glucose uptake. In the present study we sought to determine if the heart was also less responsive to the positive inotropic effect of insulin during non-cardiogenic endotoxin shock. Responses of the heart to insulin were assessed under conditions of hyp...

The adenosine-receptor antagonist 8-phenyltheophylline (8-PTH) was used to study the role of endogenous adenosine in modulating insulin-stimulated myocardial glucose uptake (MGU) in vivo. Dogs were surgically instrumented under pentobarbital sodium anesthesia to measure hemodynamics and obtain blood samples for determinations of oxygen and glucose...
