We employ electrophysiological and molecular techniques to examine the excitability of cortical neurons in rats and mice. Our work focuses on the interplay of inhibitory and excitatory influences, especially as they relate to the genesis of synchronicity in neuronal networks. These processes are fundamental for understanding the mechanisms underlying the generation of seizures in epileptic patients and for developing new anti-epileptic drugs. We are also stutying a mouse model of Fragile X syndrome to identify the alterations in inhibition that occur in a specific brain structure, the subiculum. This aspect might represent a fundamental mechanism in the pathophysiogenesis of this form of mental retardation.

The Bourque lab studies how the mammalian brain monitors the ratio of salt to water (fluid osmolality) via special neurons called osmoreceptors. We are interested in how mechanosensitive ion channels and neuro-glial interactions allow osmoreceptors to detect changes in extracellular fluid osmolality. We are also interested in how synaptic signals distributed in central osmoregulatory circuits mediate changes in behavior (thirst, salt appetite), hormone release and autonomic function to adjust blood pressure, blood volume and fluid osmolality. Finally, we are interested in mechanisms that modulate osmoregulatory circuits. In particular, we are investigating the basis for modulation by changes in blood volume and body temperature, as well as for the circadian modulation of osmoregulatory function. .

My research interests have always been in the Neurosciences, particularly in the physiology of somatic sensory systems in the periphery and the spinal cord. My work has focussed on the physiology of pain and nociceptive systems with a special interest in the mechanisms of hyperalgesia and on pain of visceral origin. The main objective of the research during the last few years has been the study of the neurobiological mechanisms of pain and analgesia based on investigations ranging from human psychophysics, to cellular and molecular analysis in experimental animals.

Current projects include: Development of models of visceral pain and referred hyperalgesia in mice. Studies of hyperexcitability of spinal nociceptive systems in models of Functional Abdominal Pain. Role of a central pre-synaptic interaction between low threshold afferent fibres and nociceptor afferent terminals in the generation of allodynia via a mechanism involving primary afferent depolarisation and dorsal root reflexes. Role of the NKCC1 chloride co-transporter in the generation of hyperalgesic states. Identification of molecular targets known to participate in the development of central hyperexcitability states. Mechanisms of release of ATP and other factors from urinary bladder epithelial cells that may mediate interstitial cystitis.

Cells must discriminate among a plethora of signals and in many instances must be able to integrate signals coming from several different pathways. Thus, the cell must simultaneously facilitate this crosstalk between receptor pathways and paradoxically limit it in order to preserve specificity.The mechanisms which regulate specificity of G protein-coupled signalling systems in vivo are not well characterized. In vivo, GPCRs demonstrate much less promiscuity in their coupling to G proteins and effectors than in vitro. We feel it is therefore important to use cellular systems to begin to look at mechanisms of specificity. Thus, the question of specificity may be addressed by positing that signalling complexes are stable in these cells and that receptors, G proteins and effectors remain associated even while activated. Work in my lab is based on the idea that stable receptor/G protein/effector interactions can serve to explain the specificity inherent in these signal transduction.

The goal of our research is to further understand intracellular signaling pathways at the molecular level in order to decipher alterations responsible for the development of human pathologies such as cancer and diabetes. Currently, the laboratory focuses on the role of the adaptor protein Nck in regulating the activity of various signaling pathways initiated in cells exposed to various stress conditions. We use a combination of in vitro and in vivo approaches (cellular and animal models) to investigate the impact of Nck and other adaptor proteins on various aspects of regulation of signaling events and associated biological responses. Our long term research goal is to identify novel therapeutic targets and prognostic indicators of human diseases, particularly cancer and diabetes.

Primary research interest is to investigate the role of smooth muscle in airway hyperresponsiveness and asthma. Dr. Lauzon's current research program addresses this question in the following ways:
1) By investigating the smooth muscle myosin heavy chain isoform expression in human bronchial biopsies and in genetic and allergic models of airway hyperresponsiveness using such techniques as quantitative real-time PCR and Western blotting;
2) By investigating the biophysical molecular properties of different SMMHC isoforms and actin regulatory proteins using such techniques as the laser trap (to measure the unitary displacement and force generated by single myosin molecules) and the in vitro motility assay (to measure the velocity of actin filaments as they get propelled by myosin molcules);
3) To study the biophysical properties of airway smooth muscle at the strip level to dissect out the relative contribution of the mechanics of the contractile proteins and their activation mechanisms.
4) To investigate fundamental properties of smooth muscle such as the latch-state. Specifically, the role of different smooth muscle myosin isoforms and the role of MgADP in the formation of the latch-state are addressed.

My research program is aimed at understanding the basis for asthma, a disease of epidemic proportions, through the study of cellular and animal models. The role of the T cell in airway narrowing and in inflammation is being addressed through techniques that quantify the responsiveness of the airways to bronchoconstrictive stimuli , allergen-induced bronchoconstriction and inflammation and airway remodeling. The current focus is on the role of Th2 cells, epidermal growth factor receptor and ligands and growth of airway smooth muscle. These studies are complemented by studies of isolated airway smooth muscle in culture alone and in co-culture with T cells. In vivo and in vitro indices of proliferation are used to track muscle growth, intracellular calcium signals to evaluate changes in contractile properties and flow cytometry to phenotype T cells.

Receptor Tyrosine Kinases; Insulin; Insulin-like growth factors (IGFs).
My laboratory focuses on the study of insulin and growth factor action with a particular emphasis on their relationship to the pathogenesis of Type 2 Diabetes Mellitus. Both insulin and IGF bind to their cell surface receptors, which are tyrosine kinases, leading to their activation and internalization into the endosomal system. Novel substrates of both the insulin receptor kinase (IRK) and the EGF receptor kinase (EGFRK) have been identified within endosomes. We identified a novel class of phosphotyrosine phosphatase (PTP) inhibitors - the peroxovanadium (pV) compounds - as potent insulin mimickers. pVs promote activation of the IRK, both in situ and in vivo by inhibiting an IRK-associated PTP, leading to IRK activation and a range of insulin effects, including hypoglycemia in normal and diabetic rats. A current focus is on the role of intraendosomal processes as regulators of IRK function. These include the modulation of intraendosomal pH, a specific endosomal acidic insulinase (EAI), and PTPs, all of which modulate IRK activation and insulin signaling. Defects in one or more of these processes could contribute to the pathogenesis of T2DM. In a recent collaboration we employed Genome wide scanning and proteomics to identify a number of novel genes and proteins which could contribute to the development of T2DM. We are following up these studies to further our understanding of insulin and growth factor signalling and their abnormalities. In this regard emphasis is being placed on how EGF and insulin signalling use very similar intracellular pathways and yet produce responses highly specific to each agent.

The primary research interests are in areas of artificial cell encapsulation, biomaterial and medical device engineering, tissue engineering, cell therapy and development of bioengineered controlled-release delivery system. The focus is to design artificial cell microcapsules that are capable of targeting specific sites and encapsulating genetically engineered cells and microorganisms, enzymes, small peptides, DNA and active drugs. Specifically, we are developing a system that integrates tissue engineering with gene and cell therapy methods with the aim to get therapeutic gene products to the targeted sites and maintain their functions for therapeutic applications by implanting live genetically engineered cells. Additionally, the research program is directed toward understanding the basic mechanisms that govern the use of microcapsules for oral delivery of therapeutic agents and developing support systems for artificial liver and kidney.

Investigation of the molecular mechanisms of prostate and breast cancer invasion and metastasis. Development of novel therapeutic strategies.

The focus of research in my laboratory is to investigate the progression of hormone dependent malignancies (breast and prostate cancer). Toward these objectives, I am examining the role of urokinase (uPA) in the process of tumor invasion, growth and metastasis. The change in the methylation status of uPA promoter is being evaluated as the epigenetic mechanism regulating uPA gene transcription in normal, early, and late stage breast and prostate cancer. We are developing novel diagnostic and therapeutic strategies to block uPA production and its interaction with cell surface uPAR to block tumor growth and metastasis. Using our well established models of breast and prostate cancer which closely mimics the behavior of these cancers including their propensity to develop skeletal metastasis, we are examining the efficacy of small molecules, peptides, monoclonal antibodies, oligonucleotides, and gene therapy for further evaluation in patients with these common cancers. Additionally we are developing highly sensitive and reliable molecular approaches to determine the levels of uPA expression including methylation specific PCR which can predict the methylation status of uPA, invasive potential of tumor cells and response to therapy. These results will help design an effective therapeutic strategy to block uPA/uPAR interaction.

Since both breast and prostate cancer have a high propensity to develop skeletal metastases we are continuing to examine the role of parathyroid hormone related peptide (PTHrP) in hypercalcemia of malignancy. Using our syngeneic and xenograft models of prostate and breast cancer we are examining the capacity of peptides and small molecules directed against prostate secretory proteins, integrins and intracellular signaling pathways to block the development and progression of skeletal metastases.
