Résumé :

Tese de doutoramento, Philosophy (Medicine), Institute of Medicine, Department of Molecular and Clinical Medicine, University of Gothenburg, Sahlgrenska Academy, 2012
The immunosuppressive agents (IAs) rapamycin, cyclosporin A and tacrolimus, as well as glucocorticoids are used to prevent rejection of transplanted organs and to treat autoimmune disorders. Despite their desired action on the immune system, these agents have serious longterm metabolic side-effects, including dyslipidemia and new onset diabetes mellitus after transplantation. The overall aim is to study the effects of IAs on human adipose tissue glucose and lipid metabolism, and to increase our understanding of the molecular mechanisms underlying the development of insulin resistance during immunosuppressive therapy. In Paper I and II, it was shown that rapamycin and the calcineurin inhibitors, cyclosporin A and tacrolimus, at therapeutic concentrations, had a concentration-dependent inhibitory effect on basal and insulin-stimulated glucose uptake in human subcutaneous and omental adipocytes. Rapamycin inhibited mammalian target of rapamycin complex (mTORC) 1 and 2 assembly and phosphorylation of protein kinase B (PKB) at Ser473 and of the PKB substrate AS160, and this leads to impaired insulin signalling (Paper I). On the other hand, cyclosporin A and tacrolimus had no effects on expression or phosphorylation of insulin signalling proteins (insulin receptor substrate 1 and 2, PKB, AS160), as well as the glucose transport proteins, GLUT4 and GLUT1 (Paper II). Instead, removal of GLUT4 from the cell surfasse was observed, probably mediated through increased endocytosis, as shown in L6 musclederived cells. These studies suggest a different mechanism for cyclosporin A and tacrolimus, in comparison to rapamycin, with respect to impairment of glucose uptake in adipocytes. In Paper III, all three IAs increased isoproterenol-stimulated lipolysis and enhanced phosphorylation of one of the main lipases involved in lipolysis, hormone-sensitive lipase. The agents also inhibited lipid storage, and tacrolimus and rapamycin down-regulated gene expression of lipogenic genes in adipose tissue. All three IAs increased interleukin-6 (IL-6), but not tumor necrosis factor α (TNF-α ) or adiponectin, gene expression and secretion. In Paper IV, we proposed that FKBP5 is a novel gene regulated by dexamethasone, a synthetic glucocorticoid, in both subcutaneous and omental adipose tissue. FKBP5 expression in subcutaneous adipose tissue is correlated with clinical and biochemical markers of insulin resistance and adiposity. In addition, the FKBP5 gene product was more abundant in omental than in subcutaneous adipose tissue. In conclusion, adverse effects of immunosuppressive drugs on human adipose tissue glucose and lipid metabolism can contribute to the development of insulin resistance, type 2 diabetes and dyslipidemia in patients on immunosuppressive therapy. The cellular mechanisms that are described in this thesis should be further explored in order to mitigate the metabolic perturbations caused by current immunosuppressive therapies. The findings in this thesis could potentially also provide novel pharmacological mechanisms for type 2 diabetes as well as other forms of diabetes.

Résumé :

The ability to incorporate three-dimensional (3D) hepatocyte-laden hydrogel constructs using layered fabrication approaches into devices that can be perfused with drugs enables the creation of dynamic microorgan devices (DMDs) that offer an optimal analog of the in vivo liver metabolism scenario. The dynamic nature of such in vitro metabolism models demands reliable numerical tools to determine the optimum process, material, and geometric parameters for the most effective metabolic conversion of the perfused drug into the liver microenvironment. However, there is a current lack of literature that integrates computational approaches to guide the optimum design of such devices. The groundwork of the present numerical study has been laid by our previous study [1], where the authors modeled in 2D an in vitro DMD of arbitrary dimensions and identified the modeling challenges towards meaningful results. These constructs are hosted in the chamber of the microfluidic device serving as walls of the microfluidic array of channels through which a fluorescent drug substrate is perfused into the microfluidic printed channel walls at a specified volumetric flow rate assuring Stokes flow conditions (Re<<1). Due to the porous nature of the hydrogel walls, a metabolized drug product is collected at the outlet port. A rigorous FEM based modeling approach is presented for a single channel parallel model geometry (1 free flow channel with 2 porous walls), where the hydrodynamics, mass transfer and pharmacokinetics equations are solved numerically in order to yield the drug metabolite concentration profile at the DMD outlet. The fluid induces shear stresses are assessed both in 3D, with only 27 cells modeled as single compartment voids, where all of the enzymatic reactions are assumed to take place. In this way, the mechanotransduction effect that alters the hepatocyte metabolic activity is assessed for a small scale model. This approach overcomes the numerical limitations imposed by the cell density (∼1012 cells/m3) of the large scale DMD device. In addition, a compartmentalization technique is proposed in order to assess the metabolism process at the subcellular level. The numerical results are validated with experiments to reveal the robustness of the proposed modeling approach and the necessity of scaling the numerical results by preserving dynamic and biochemical similarity between the small and large scale model.

Résumé :

Serum albumin is the major soluble protein in the circulatory system of humans. The metabolism of drugs, their distribution, free concentration, and efficacy depend on the drug-serum albumin interaction [1]. Accordingly, it is important to study the interactions of drugs with serum albumin, which determines the pharmacology and pharmacodynamics of drugs. Quercetin (QUE), a natural polyphenol widely distributed in many plant foods, such as fruits, vegetables, nuts, seeds, grains, and tea [2], bind to serum albumin [3]. Tigecycline (TGC), is a tetracycline antibiotic widely used in the treatment of bacterial infections [4]. This study aimed to investigate the binding properties of TGC to HSA in the presence of QUE, under physiological conditions, by fluorescence spectroscopy.

Résumé :

Glucagon-like peptide-1 is an isulin-like peptide hormone from the incretin family. The most popular pharmaceutical analogue of GLP-1 at the moment is liraglutide. GLP-1 receptors are localized in many areas of the brain responsible for the regulation of metabolic processes and eating behavior and in specific areas of the pancreas, heart, blood vessels, immune system, skin and adipose tissue, gastrointestinal tract and kidneys. We can definitely say that the effect of liraglutide extends to all tissues equipped with GLP-1 receptors, while the effect of the drug on the cardiovascular system, immune system, kidneys and gastrointestinal tract is still being studied. Also interesting is the possible effect of liraglutide on the liver, as an organ directly related to lipid and carbohydrate metabolism. In this article, we analyze the possibilities of using Saxenda, the main active ingredient of which is liraglutide, to potentiate the hepatoprotective effects of the Hepaton-vet drug in groups of rats with induced hepatopathy, evaluating the effect of these drugs on the parameters of a clinical blood test.

Résumé :

Intranasal drug delivery is an attractive route to noninvasively achieve a rapid therapeutic effect, avoid first pass metabolism, and bypass the blood brain barrier. However, the types of drugs that can be administered by this route has been limited, in part, by device technology. Herein, we describe a pneumatic nasal spray device that is capable of mixing liquid and solid components of a drug formulation as part of the actuation process during dose administration. The ability to store a nasal spray drug formulation as two separate components can be leveraged to solve a variety of stability issues that would otherwise preclude intranasal administration. Examples of drugs that could be delivered intranasally by utilizing this two-part formulation strategy include biomolecules that are unstable in solution and low solubility drugs that can be rendered into metastable supersaturated solutions. A proof of concept nasal spray device prototype was constructed to demonstrate that a liquid and solid can be rapidly mixed and atomized into a spray in a single action. The primary breakup distance and angle of the spray cone were measured as a function of the function of the propellant gas pressure.

Résumé :

Pharmacokinetics of drugs involves the study of the drug’s path through the body, from its introduction to its final excretion from the body (Absorption, Distribution, Metabolism, and Excretion (ADME)). The basis of pharmacokinetic tests provides insight into the behavior of the tested substance after it is introduced into the body. They include consideration of the physicochemical properties of the medicinal substance, as well as its biopharmaceutical properties. Experimental measurements are often demanding and take a long time to conclude the continuation of further research, whether it is a natural or synthesized substance that could be used as a medicine. In silico testing is resorted to because of the high cost of experimental testing. That is why today more and more research is done theoretically using different chemoinformatics tools. Using the results obtained theoretically or in silico related to key parameters such as solubility, degree of dissociation, and binding to plasma proteins, it is possible to successfully predict the fate of the drug in the body, i.e., its bioavailability. There is a large number of software that are free to obtain the desired information about solubility, metabolism, distribution, and excretion from the organism. In this work, we decided to examine the solubility and lipophilicity of coumarin with three chemoinformatics tools.

Résumé :

A cell culture microfluidic device has been developed to test the cytotoxicity of anticancer drugs while reproducing multi-organ interactions in vitro. Cells were cultured in separate chambers representing the liver and tumor. The two chambers were connected through a channel to mimick the blood flow. Glioblastoma (GBM) cancer cells (M059K) and hepatoma cells (HepG2) were cultured in the tumor and the liver chambers, respectively. The cytotoxic effect of cancer treatment drug Temolozomide (TMZ) was tested using this two chamber system. The experimental results showed that with the liver cells, the cancer cells showed much higher viability than those without the liver cells. This indicates that the liver metabolism has strong effect on the toxicity of the anticancer drug. The results demonstrated that the perfused two chamber cell culture system has the potential to be used as a platform for drug screening in a more physiologically realistic environment.

Review question / Objective: The aim of this review is to evaluate the effectiveness of Cerus and Cucumis Polypeptide injection combined with Bisphosphonates for postmenopausal osteoporosis. Condition being studied: Postmenopausal osteoporosis (PMOP) is a disorder of bone metabolism caused by estrogen deficiency in women after menopause, which manifests clinically as pain, spinal deformities and even fragility fractures, affecting the quality of life of patients and possibly shortening their life span. Bisphosphonates are commonly used to control and delay the progression of the disease, improve the patient's symptoms and reduce the incidence of fragility fractures. However, single drugs are still lacking in controlling the progression of the disease, and the combination of drugs is the clinical priority.

Résumé :

Review question / Objective: To evaluate the efficacy of different anti-diabetic drugs in the treatment of non-diabetic non-alcoholic disease by network meta-analysis, and find the best intervention. Condition being studied: Non-alcoholic fatty liver disease (NAFLD) refers to the disease in which the liver fat content exceeds 5%, and excludes the secondary causes of alcohol, infection, drugs or other specific metabolic diseases. As a spectrum of disorders, it includes hepatocyte steatosis and steatohepatitis at the initial stage, liver fibrosis at the later stage, cirrhosis at the final stage, and even liver cancer. Nowadays Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease in the world with an incidence rate as high as 25% which has been rising steadily worldwide in the past 30 years. Currently there are still no approved specific therapeutic agents and global treatment guidelines for NAFLD. For non-diabetic NAFLD, there is far from a consensus, too.

Résumé :

Review question / Objective: P (patient population) = Type 2 diabetes patients with high CV risk or established atherosclerotic cardiovascular disease; I (intervention) = Received drugs: GLP1-RA; C (control group) = Compared to a control group that received a placebo; O (outcome) = Outcomes of interest included primary CV outcomes (MACE, CV death, MI, and Stroke). Condition being studied: To explore whether the heterogeneity associated with the primary outcomes benefits can be attributed to the metabolic improvements associated with GLP1-RA. The plan is to use HBA1c, weight, and SBP reduction as moderators attempting to explain any variance between the true and observed effect size.

Résumé :

Review question / Objective: P：Liver cirrhosis patients with risk factors associated with HE attack;HE patients caused by chronic liver diseases represented by cirrhosis. I: Rifaximin treatment. C: Other drugs or placebo. O：HE incidence; HE improvement; All-cause mortality; Blood ammonia level; PSE index; mental state; NCT-A; NCT-B; Adverse events. Condition being studied: Hepatic encephalopathy(HE) is a neuropsychiatric disorder syndrome based on metabolic disorders, which is caused by severe acute and chronic liver dysfunction or various abnormalities of portosystemic shunt (hereinafter referred to as portosystemic shunt). The research data shows that the prevalence of OHE in patients with cirrhosis is 10-14%, and the prevalence of HE in patients with decompensated cirrhosis is 16-21%. HE can lead to 60-80% of patients with liver cirrhosis with mild cognitive impairment, affecting their ability of daily life and quality of life. When OHE occurs, the one-year mortality rate of patients with liver cirrhosis is 64%, which brings a heavy economic burden to patients and public health resources. Therefore, the prevention and early management of HE is very important.

Résumé :

Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds. This highly-synergistic one year project implemented an innovative pipeline aimed at detecting BCAs and associated biologically-active compounds, which included: (A) isolation of multidrug-resistant desert soil bacteria and root-associated bacteria from medicinal plants; (B) invitro screening of bacterial isolates against known plant, animal and human pathogens; (C) nextgeneration sequencing of isolates that displayed antagonistic activity against at least one of the model pathogens and (D) in-planta screening of promising BCAs in a model bean-Sclerotiumrolfsii system. The BCA genome data were examined for presence of: i) secondary metabolite encoding genes potentially linked to the anti-pathogenic activity of the isolates; and ii) rhizosphere competence-associated genes, associated with the capacity of microorganisms to successfully inhabit plant roots, and a prerequisite for the success of a soil amended BCA. Altogether, 56 phylogenetically-diverse isolates with bioactivity against bacterial, oomycete and fungal plant pathogens were identified. These strains were sent to Auburn University where bioassays against a panel of animal and human pathogens (including multi-drug resistant pathogenic strains such as A. baumannii 3806) were conducted. Nineteen isolates that showed substantial antagonistic activity against at least one of the screened pathogens were sequenced, assembled and subjected to bioinformatics analyses aimed at identifying secondary metabolite-encoding and rhizosphere competence-associated genes. The genome size of the bacteria ranged from 3.77 to 9.85 Mbp. All of the genomes were characterized by a plethora of secondary metabolite encoding genes including non-ribosomal peptide synthase, polyketidesynthases, lantipeptides, bacteriocins, terpenes and siderophores. While some of these genes were highly similar to documented genes, many were unique and therefore may encode for novel antagonistic compounds. Comparative genomic analysis of root-associated isolates with similar strains not isolated from root environments revealed genes encoding for several rhizospherecompetence- associated traits including urea utilization, chitin degradation, plant cell polymerdegradation, biofilm formation, mechanisms for iron, phosphorus and sulfur acquisition and antibiotic resistance. Our labs are currently writing a continuation of this feasibility study that proposes a unique pipeline for the detection of BCAs and biopesticides that can be used against phytopathogens. It will combine i) metabolomic screening of strains from our collection that contain unique secondary metabolite-encoding genes, in order to isolate novel antimicrobial compounds; ii) model plant-based experiments to assess the antagonistic capacities of selected BCAs toward selected phytopathogens; and iii) an innovative next-generation-sequencing based method to monitor the relative abundance and distribution of selected BCAs in field experiments in order to assess their persistence in natural agro-environments. We believe that this integrated approach will enable development of novel strains and compounds that can be used in large-scale operations.
