Kiss1r Signaling Promotes Breast Cancer Metastasis, Cameron G-F Goertzen
Electronic Thesis and Dissertation Repository
Kisspeptins, peptide products of KISS1, are endogenous ligands for KISS1R, a G protein-coupled receptor. In numerous cancers, KISS1 acts as a metastasis suppressor. However, studies have revealed that patients with elevated KISS1 and KISS1R breast tumor expression have increased tumor grade, increased lymph node metastases and poor survival. We hypothesize that depletion of KISS1R inhibits breast cancer cell metastasis. In order to assess the role of KISS1R in breast cancer metastasis, we used a pre-clinical orthotopic xenograft mouse model using MDA-MB-231 breast cancer cells for breast tumor establishment. We discovered that depletion of KISS1R decreased primary tumor growth and …

Economic Evaluation Of Potential Applications Of Gene Expression Profiling In Clinical Oncology, Malek Hannouf
Electronic Thesis and Dissertation Repository
Histopathological analysis of tumor is currently the main tool used to guide cancer management. Gene expression profiling may provide additional valuable information for both classification and prognostication of individual tumors. A number of gene expression profiling assays have been developed recently to inform therapy decisions in women with early stage breast cancer and help identify the primary tumor site in patients with metastatic cancer of unknown primary. The impact of these assays on health and economic outcomes, if introduced into general practice, has not been determined. I aimed to conduct an economic evaluation of regulatory-approved gene expression profiling assays for …
