Research Focus in the Fraizer Laboratory: Cancer, Mechanisms of tumorigenesis
Dr. Fraizer’s laboratory uses molecular and genetic approaches to delineate mechanisms of tumor development, including angiogenesis and metastasis. Dr. Fraizer’s research has examined proliferation, migration and gene expression in urologic and hematologic tumors. A major focus is the investigation of angiogenic and metastatic adaptation of prostate cancer cells. Our approach has been to examine regulators of androgen signaling including zinc finger transcription factors such as Sp1 and the Wilms' tumor gene (WT1). Research elucidating the mechanisms of WT1 and Sp1 mediated regulation of the vascular endothelial growth factor (VEGF) in prostate cancer cells grew out of our microarray analyses of RNA obtained from Laser Capture microscopy of prostate tissues and from cultured prostate cancer cells. One long-term goal of the lab is to understand how WT1 and Sp1 alter androgen induction of VEGF. Another is to determine whether WT1 enhances motility by contributing to epithelial-mesenchymal transition (EMT), a process required for metastatic progression. These studies will contribute to identification of pathways utilized in prostate cancer progression/metastasis and may ultimately impact diagnosis and possibly therapy of prostate cancer. A more recent focus for the lab has been motivated by the long suspected but still unknown role of WT1 in hematopoietic cell transformation. We have recently discovered a potential link between WT1 and cell cycle regulators in acute leukemia. These studies could ultimately address the balance between proliferation and differentiation of hematopoietic precursors. Overall the goal of Dr. Fraizer’s research is to delineate tumor mechanisms that provide potential targets for therapy.
