Our goal is to understand the role of spatial chromatin organization in the regulation of gene expression in mammalian cells.

We are characterizing the molecular mechanisms involved in regulating the three-dimensional chromatin architecture and expression of Hox genes in leukemia cell models.
Duchaine, Thomas, Associate Professor

RNAi is the process through which small non-coding RNAs direct a diverse set of gene-silencing processes. My group is interested in the underlying mechanisms, and their implications in development and cancer. Through a combination of genetics, cell biology, biochemistry and proteomics and using the nematode C. elegans, we examine the molecular machines involved in RNAi, and decipher how they orchestrate gene silencing. Currently, my group focuses on two distinct ‘branches’ of the RNAi processes: endoRNAi and microRNA-mediated silencing. First, we examine a phenomenon termed endogenous RNAi (endoRNA) which is naturally initiated on certain messenger RNAs, and results in the shutdown of the gene's expression. We are particularly interested in the functional interactions between endoRNAi and chromatin, the physiological scaffold of the genome. Second, we are interested in how microRNA-mediated gene silencing touches upon genetic programs in the developing embryo, and in cancer cells. Our findings have implications for the understanding of gene networks in all animals, including humans.

Our laboratory uses a genetic approach in mouse to discover genes, proteins and pathways that play an important role in complex human diseases. Our long-term objectives are to translate knowledge obtained in laboratory mouse models, into clinical outcomes through the creation of novel diagnostic tools or new small molecules modulators with therapeutic value in the corresponding human disease. We are currently focusing on three major human diseases known to have clear genetic component: infectious diseases, cancer, and the birth defect spina bifida.

McInnes, Roderick, Professor
roderick [dot] mcinnes [at] mcgill [dot] ca
Our lab is interested in two major questions in biology and medicine. First, in inherited neurodegenerations, we wish to understand what is happening in the mutant neurons, in the years to decades between their birth and their death years to decades later. After decades of normal function, why do the neurons suddenly die? To address this question, we are identifying molecular mechanisms that contribute to, or protect against the death of mutant photoreceptors (PRs) in inherited photoreceptor degenerations (IPDs) using mouse models of these diseases. Understanding of these mechanisms is likely to suggest therapeutic opportunities that will slow or arrest PR death. Second, we wish to understand the roles of “accessory” proteins in the regulation of ion channels in neurons, particularly at synapses. Our focus is on two such proteins that we discovered, Neto1 and Neto2. The Neto proteins are multifunctional, as indicated by their loss-of-function phenotypes, which include defects in axon guidance, seizures in some genetic backgrounds, defects in memory and learning, and abnormal regulation of neuronal excitability. To date, we have identified at least 5 ion channels or other neuronal proteins whose activity is or appears to be regulated by a Neto. Elucidation of the role of the Netos in the brain is increasing our understanding of a surprisingly broad range of fundamental neuronal processes.
Muller, William, Professor
william [dot] muller [at] mcgill [dot] ca
The progression of the primary mammary epithelial cell to malignant phenotype involves multiple genetic events including the activation of dominant activating oncogenes and inactivation of specific tumor suppressor genes. Our laboratory has focused on the role of a class of receptor tyrosine kinases known as the epidermal growth factor receptor (EGFR) family in the induction of breast cancer .Elevated expression of the various EGFR family members has been observed in a large proportion of sporadic breast cancers and their derived cell lines. For example, amplification and overexpression of erbB-2/neu proto-oncogene is observed in 20-30% human breast cancer and is inversely correlated with the survival of the patient. The major focus of our laboratory is to determine the relative contribution of the various EGFR family members and their coupled signaling pathways in ErbB-2 induced mammary tumor progression. Given the fact that germline inactivation of these signaling pathways results in either embryonic or perinatal lethality, we have used use Cre/Lox recombination system to specifically inactivate each of these signaling molecules members in the mammary epithelium of mice expressing activated erbB-2. The results of these biochemical and genetic analyses will provide important insight in molecular basis for erbB-2 induced tumorigenesis and metastasis.

St-Pierre, Julie, Assistant Professor
julie [dot] st-pierre [at] mcgill [dot] ca
Mitochondria play a central role in basic physiological functions by producing most of the cellular ATP. Furthermore, mitochondria are important for cellular functions such as heat production, generation of reactive oxygen species (ros) and execution of the apoptotic program. Given the key role of mitochondria in various cellular events, it is not surprising that mitochondrial dysfunctions are seen in many pathological conditions such as neurodegeneration, diabetes, aging and cancer. The aim of my research is to understand the regulation of mitochondrial metabolism under physiological and pathological conditions using unbiased screening approaches, notably metabolic profiling in combination with global gene expression analysis.

Teodoro, Jose, Associate Professor
jose [dot] teodoro [at] mcgill [dot] ca
Projects in the lab identify and characterize pathways that target tumour growth. The first project studies how the p53 tumour suppressor pathway is able to inhibit angiogenesis. Angiogenesis is the process of blood vessel formation that is required for tumour formation. Molecular and proteomic approaches are used to identify p53-induced angiogenesis inhibitors and define how such factors work. The second project in the lab studies cytotoxic viral proteins and how such factors destroy cancer cells. A number of such viral proteins interact with and inhibit a protein complex called the Anaphase Promoting Complex/Cyclosome (APC/C). Work in the lab seeks to determine why the APC/C is a general target of many viruses and how inhibition of this complex can lead to specific destruction of cancer cells.

jason [dot] young2 [at] mcgill [dot] ca
In cells, the folding of polypeptides into mature proteins depends on a specialized class of proteins termed ‘molecular chaperones’, which also protect against potentially toxic polypeptide aggregation. Two of the most important cytosolic chaperones, Hsp70 and Hsp90, are themselves controlled by regulatory ‘co-chaperone’ proteins. My research investigates the biochemical mechanisms of these regulated chaperone systems, how they function in protein folding and in the biogenesis of organelles such as mitochondria.

We study transcriptional mechanisms controlling cell differentiation, cell identity and hormone action. These studies use the pituitary gland as a convenient model since it is a relatively simple tissue composed of six related cell types. A particular emphasis is placed on novel transcription factors cloned in the lab, such as the homeobox transcription factors Pitx1/2/3 and Tbox factor Tpit.
The role of Pitx1, Tbx4 and Tbx5 in specification of limb identity is also investigated with a particular emphasis on the evolutionary more recent program from hindlimb development.
Classical molecular biology approaches, incl. mouse models, are combined with recent genome-wide technologies, such as microarray-based profiling and ChipSeq, for a global view of regulatory mechanisms.
Fon, Edward, Associate Member
ted [dot] fon [at] mcgill [dot] ca
Dr. Edward Fon is a neurologist and scientist who serves as the Director of the McGill Parkinson Program, a National Parkinson Foundation Centre of Excellence. His research focuses on the molecular events leading to the degeneration of dopamine neurons in Parkinson's disease. In the past decade, several genes have been identified that cause some forms of the disease. He is particularly interested in how these genes come together and interact to cause Parkinson's disease. His work focuses on one of these genes, Parkin, which functions as a key enzyme in the main protein degradation pathway in the cell. This pathway utilizes ubiquitin, a protein that can mark target proteins for degradation. Dr. Fon’s laboratory works on understanding the various functions of ubiquitin in the nervous system and on how defects in parkin could lead to Parkinson’s disease. This work could provide important clues about the mechanisms of dopamine neuron death in Parkinson’s disease and potentially lead to innovative new therapeutic strategies.

The goal of my ongoing research is to implement the recombinant congenic mouse strains (RCS) platform (originally developed by Dr. Emil Skamene at the MGHRI) to isolate single gene effects in diseases of human relevance. The AcB/BcA RCS platform, which represents a valuable and versatile genetic tool to study complex phenotypes, is used by our group to study a series of complex phenotypes including malaria susceptibility, lipid metabolism, nociception and bone formation. This project provides the unique opportunity to gain insight on complex trait architectures in terms of loci and traits interactions, which is of great interest to me.

Heart disease remains the major cause of death and disability in our society. A major cardiovascular risk factor is a low level of high-density lipoproteins (HDL) in plasma. Our laboratory has two major focus of research: 1) the study of genes associated with HDL metabolism by examining large, informative families with HDL deficiency and 2) the mechanisms of HDL biogenesis in man. The genetic project uses linkage analysis of the low HDL trait by a binary approach (affected or not) and the search for quantitative trait loci (QTL). Genome-wide scans, genome-wide exome sequencing and deep re-sequencing strategies are used to identify novel genes. For the study of HDL biogenesis, our approach uses molecular cellular physiology, detailed biochemical analysis of plasma membrane components, proteomics and tandem-MS lipidomics, confocal microscopy and genetic manipulation (using specific cell lines from various tissues and human disease states) approaches to study cholesterol and phospholipid transport onto nascent HDL particles. Most of our work focuses on ATP binding cassette transporters ABCA1 and ABCG1. We also study the pleiotropic effects of HDL on vascular endothelial cells.

Hallett, Michael, Associate Member
hallett [at] mcb [dot] mcgill [dot] ca
Dr. Hallett's lab is primarily interested in the use of bioinformatics and systems biology approaches to the study of breast cancer. In particular, his group is involved in several studies to analyze high-throughput profiles (gene expression, epigenetic, microRNA) in both mouse models of breast cancer and the human disease. For example, one of their primary goals is to identify genes or small gene sets that are predictive of patient outcome, response to therapy, or disease progression. These genes or gene sets can be developed into clinical-applicable devices that assist in the determination of patient therapy.
They are also interested in the development of new bioinformatics tools that provide global perspective of the dynamics of the disease. For example, we use bioinformatics to identify sets of genes that stratify the patient population into distinct groups. These groups reflect different types of breast cancer and each subtype may require a distinct therapeutic regime. They are particularly interested in investigating how differences in the tumor microenvironment (the area around the tumor) hinder or help the progression of a tumor. These signals may also be used by clinicians to assist in assigning patient treatment.

gergely [dot] lukacs [at] mcgill [dot] ca
The cystic fibrosis gene product, CFTR, is a multidomain, polytopic plasma membrane protein that belongs to the ATP-Binding Cassette transporter family. The chloride channel activity of CFTR is indispensable for normal transcellular salt and water transport in numerous organs (e.g. gastrointestinal tract, pancreas and sweat duct) and for the homeostasis of airway surface liquid layer. Our long-term goal is to elucidate the molecular and cellular basis of cystic fibrosis, one of the most prevalent genetic diseases in the Caucasian population, caused by mutations interfering with the folding, stability, activity and/or membrane trafficking of the channel. To achieve this goal, we utilize a combination of biochemical, biophysical, cell biological and genetic techniques. Another aspect of our inquiries is to gain insights into the recognition and elimination mechanism of non-native membrane proteins from post-ER/Golgi compartments in mammalian cells. The peripheral quality control of integral membrane proteins likely represents a fundamental protective mechanism against the accumulation of aggregation prone and toxic polypeptides that are generated by cellular stresses or mutations. Using conditionally misfolded model proteins, we aim at identifying the machinery responsible for the disposal of non-native plasma membrane proteins. The structural and biochemical basis of ubiquitin recognition as an endocytic and postendocytic sorting signal is also investigated.

Research in my laboratory focuses on understanding the cellular and molecular mechanisms responsible for the initiation and maintenance of steroid biosynthesis in the adrenal, gonads and brain, in health and disease. We also examine the regulation of steroid biosynthesis, intracellular compartmentalization and homeostasis by hormones, chemicals, drugs, natural products and environmental factors. Our goal is to understand the pathophysiology of steroidogenesis and develop new tools for the treatment of diseases related to elevated or low steroid levels or alter subcellular steroid compartmentalization as a means to block disease acquisition and/or progression. In these studies we are using biochemical, pharmacological, and molecular methods as well animal models of disease to identify the physiological role of critical components of the steroidogenic pathway and identify pathological situations created by changes in the expression of these components in animals and humans. Drug design methods and molecular modeling help us modify existing chemical entities and generate novel ones targeted at key elements of the steroidogenic machinery. Our research has direct applications in reproduction and development, cancer, stress-related disorders, aging and brain related dysfunction, such as Alzheimer’s disease pathology.

The three related species of trypanosomatids, Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, cause serious human and animal diseases, with a very high incidence and mortality rate if untreated. There are no vaccines for these pathogens, the drugs are toxic with limited effectiveness, and drug resistance is emerging. The availability of the genome sequences of these organisms since 2005 has dramatically expanded our knowledge of their biology; however, a major obstacle has since been acknowledged: the majority of trypanosomatid genes are not found in any other organism, making it almost impossible to use homology-based methods for inferring their functions from their sequences. Our lab is focused on development of novel computational and experimental methods for functional and structural characterization of trypanosomatid genomes. We are also involved in development of high-throughput methods for identification of novel chemical inhibitors of essential trypanosomatid proteins, particularly the editing complex of T. brucei. Functional characterization of some of the key trypanosomatid proteins that are involved in RNA editing is also among the major research topics of our lab.

Research in my laboratory involves elucidating the cellular and molecular Our projects focus on the design and synthesis of small molecule ligands that can bind to mammalian or microbial targets modulating their function. Our main objective is to design chemical tools that can facilitate investigations into the biological role of proteins associated with a disease state.
Currently, a number of our projects involve structure-based ligand design targeting the human enzyme farnesyl pyrophosphate synthase (hFPPS). A key objective of these projects is to synthesize novel active site or allosteric site inhibitors of hFPPS that could potentially serve as “leads” for the design of better therapeutic agents for the treatment of osteoporosis, cancer and viral infections. However, the ultimate goal of these studies is to provide greater insight into the biological significance of post-translational prenylation of proteins and elucidate the role of hFPPS in the innate immune response during viral infections.

Research in my laboratory relates to functional genomics in budding yeast and pathogenic fungi. We are focusing on the Gal4 family of transcriptional regulators that includes over fifty members in budding yeast. The function of many of these Gal4 members is unknown or poorly defined. To better understand the role of these transcriptional regulators and identify their target genes, we are using various approaches including genome-wide location analysis and expression profiling as well as genetics. We are also determining the role of related Gal4 members in conferring resistance to antifungal drugs in the human pathogens Candida albicans and C. glabrata. Another project is aimed at identifying new compounds with antifungal activity. Finally, my lab is also interested in developing compounds with antibacterial activity.

We have been interested in the question of how physiological and environmental signals get into individual cells of multicullar organisms and regulate chromatin structure and gene expression in normal and diseased states. In particular, we have been deciphering the function and regulation of histone-modifying enzymes, esp. histone acetyltransferases and deacetylases. One emerging project in the laboratory is how these enzymes and their regulators play a role in self-renewal and differentiation of various types of stem cells, including ES (embryonic stem) and iPS (induced pluripotent stem) cells.
