Studies on the functions of the mouse CEACAM1 proteins in various tissues, their association with intracytoplasmic proteins and their connection with signaling cascades using transgenic and knockout mouse models. Role of the CEACAM1 proteins in colon tumor development, progression and metastasis in genetic models. Role of the CEACAM1 proteins in angiogenesis in transgenic mice.

The focus of the Chang lab is to elucidate the molecular pathways that regulate stem cell function. We employ muscle stem cells as a model to study stem cell biology and tissue regeneration. Dysregulation of the pathways that control muscle stem cell function contribute to muscle degeneration and disease. We investigate how stem cell function is impaired in muscle degenerative disease and cancer in order to gain insight into mechanisms of disease and develop novel regenerative medicine strategies.

Our general research area is mRNA metabolism during the cell cycle and cell differentiation. We use the tools of molecular and cell biology to study problems in this field. The long-term research goals focus on understanding the cellular mechanisms involved in the regulation of mRNA half-lives and how they affect cell growth and differentiation.

Gehring, Kalle, Professor

Structural biology and biophysics of proteins and nucleic acids. The laboratory’s main research interests are poly(A) binding protein, ubiquitin-associated proteins, proteins involved in membrane trafficking, and ER protein folding. The methods used are nuclear magnetic resonance spectroscopy, X-ray crystallography and small-angle X-ray scattering in combination with the techniques of molecular biology.

Guarne, Alba, Professor
alba.guarne [at] mcgill.ca
Our goal is to understand how proteins determine the fate of DNA during chromosome replication and repair. In particular, how regulatory proteins orchestrate the stabilization of damaged replication forks with DNA repair and forks restart. Since most of the proteins that regulate these processes lack a measurable enzymatic activity, our efforts are aimed at seeing how they work using a broad range of structural biology techniques. We then combine structural information with biochemical and genetic analysis to elucidate their functions at a molecular level.

Huang, Sidong, Associate Professor
sidong.huang [at] mcgill.ca
Our laboratory uses functional genomic tools to study cancer-relevant pathways and to guide targeted cancer therapy. We aim to identify novel genes and networks that modulate response to cancer drugs, and to uncover genetic dependencies between the major signaling pathways in cancer that can be exploited therapeutically.

Kazak, Lawrence, Assistant Professor
lawrence.kazak [at] mcgill.ca
The Kazak lab combines mouse genetics, mass spectrometry, molecular and cell biology, biochemistry and bioenergetics to study the molecular control of mammalian energy metabolism. Our efforts are concentrated on the molecules and metabolic pathways that control mitochondrial energetics in adipocytes and cancer cells. We have generated novel genetically-engineered mouse models to accurately study cellular metabolism, in vivo. In the case of adipose tissue, we systematically examine mechanisms supporting adipocyte energy expenditure, which has tremendous promise for combating obesity. In the case of cancer, we are leveraging our expertise of mitochondrial biology and cellular energetics to explore novel metabolic pathways that are critical for tumorigenesis.

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.

Transcriptional regulation in normal and cancer cells (expression profiling, genome-wide location arrays (ChIP-chip)). Post-translational regulation by cyclin-dependent kinases during cell cycle progression, and by checkpoint kinases following DNA damage.

Deregulation of receptor tyrosine kinases is a common event in the development and progression of human cancers. We propose to examine the signals regulated by receptor tyrosine kinases that promote cell transformation, tumor formation and metastatic spread of tumors with a focus on breast cancer.

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.
