  • ABSTRACT Gene Expression Profiling to Understand the Alterations In
    ABSTRACT Gene Expression Profiling to Understand the Alterations in the Monocyte Compartment of Pediatric Systemic Lupus Erythematosus Pinakeen Shankarbhai Patel, Ph.D. Mentors: Virginia Pascual, M.D. Jacques Banchereau, Ph.D. Blood monocytes from SLE patients display DC function, as they are able to induce the proliferation of allogeneic T cells. Furthermore, sera from SLE patients induce healthy monocytes to differentiate into DCs. This DC-inducing property is in part due to the presence of type-I IFNs in SLE sera, as well as other, yet uncharacterized factors. To understand these alterations, we performed a thorough phenotypic analysis and gene expression profiling of monocytes from children with active, newly diagnosed and untreated disease. Phenotypic analysis of freshly isolated SLE blood monocytes revealed a modest expansion of CD14highCD16+ cells and an otherwise lack of expression of molecules related to DC function. Further characterization of a fraction of SLE monocytes inducing allogeneic T cell proliferation revealed that upon contact with T cells, SLE monocytes secrete proinflammatory cytokines such as IL-1 and IL-6 and do upregulate expression of innate immunity receptors involved in DC differentiation and molecules responsible for antigen presentation. To recapitulate the initial events leading to monocyte differentiation in this disease, we studied the effects of SLE serum on healthy monocyte at the trasncriptional and protein levels. These studies revealed the upregulation of expression on these cells of chemokine receptor such as CX3CR1 and CCR7, which may lead to the migration of blood monocytes to inflammed tissues and/or secondary lymphoid organs respectively in vivo. There, contact with T cells would lead to the acquisition of antigen presenting function and skewing from tolerogenic to immunogenic responses.

  • (Title of the Thesis)*
    THE IDENTIFICATION OF BRCA1 AND BRCA2 MUTATION CARRIERS USING FUNCTIONAL GENOMIC ASSAYS by Claire S. Michel A thesis submitted to the Department of Pathology & Molecular Medicine In conformity with the requirements for the degree of Master of Science Queen’s University Kingston, Ontario, Canada March, 2008 Copyright © Claire S. Michel, 2008 Abstract An estimated 5-10% of breast cancers are hereditary in nature and are due to the presence of a mutation in a breast cancer predisposition gene; approximately half of these cases possess a mutation in BRCA1 or BRCA2. Many BRCA1/BRCA2 mutations result in a truncated protein and hence are unequivocally disease-causing. However another class of mutations, the Variants of Unknown Significance (VUS), are more problematic as the effect of these mutations on protein function is unclear. The inability to classify these mutations as disease causing generates significant problems in risk evaluation, counseling and preventive care. Accordingly we sought to determine whether carriers of either a BRCA1 or BRCA2 mutation could be identified from non- carriers based on the gene expression patterns of non-cancerous cells. EBV-transformed lymphoblastoid cell lines established from BRCA1/BRCA2 mutation carriers and normal individuals were obtained through the NIH Breast Cancer Family Registries. Cell lines were mock-irradiated or treated with ionizing radiation (2 Gy). Following a recovery period of 6 hours total RNA was extracted and whole genome gene expression profiling was carried out. Molecular classifiers comparing the baseline expression profiles and the radiation- dependent expression profiles of BRCA1/BRCA2 mutation carriers to control individuals were created using a Support Vector Machine (SVM) coupled with a recursive feature removal (RFR) algorithm.
